A track-type vehicle undercarriage comprising a track frame, a recoil device mounted on the track frame, a mount member fixedly connected to the recoil device and biased forwardly thereby, an idler rotatably mounted on the mount member, a sprocket, and an endless track of linked together track shoes mounted around the idler and the sprocket. A support member is adjustably mounted on the mount member and a support rail is pivotally mounted at one end thereof on the support member. A separate support device is mounted on the track frame for supporting the other end of the support rail.
摘要:
A method of forming a plurality of horizontal barriers in situ at a preselected depth beneath the soil surface and in a plane substantially parallel to the soil surface so as to be coextensive with a desired area, the barriers being made of a thermoplastic material such as asphalt for example, and forming further barriers joined to the horizontal barriers and extending vertically or obliquely toward the soil surface in order to surround the above-mentioned area, thereby improving soil having a poor water retention property. The method further comprises the steps of filling up chambers in a plow moving in the soil with the barrier forming material in the liquid form, leaking the material out of the chambers through passages of a given gap, and spreading the formed film laterally uniform by an ironing portion connected with the plow near the passages so as to render the formed water barrier uniform in thickness and free from apertures.

A process and apparatus for effecting injection molding of plastic resin products on an injection molding apparatus including a metal mold composed of a slidable mold element and a fixed mold element defining together the mold cavity, an actuator for sliding the slidable mold element and an injection nozzle for adjusting the nozzle flow path section, which comprises a first molding step of injecting a molten resin into the mold cavity which has been preset by the slidable mold element so as to include a post-compression margin to be compressed afterwards in a second molding step, to effect the injection under a reduced molding pressure, while causing a temperature elevation and, thus, a viscosity reduction of the molten resin, until the mold cavity has been filled up, and a second molding step of compressing the resin so charged in the mold cavity by operating the slidable mold element to compress the charged resin to compensate the post-compression margin, so as to allow an effective pressing force to be imposed onto the charged resin within the mold cavity also after the gate has been sealed.

A plurality of article-storing columns, each of which stores therein various kinds of articles piled up and being different from others, are arranged within a machine in row and column directions. At the lower part of each of these article-storing columns, an article-push-out means for pushing out an article at the lowest layer, respectively. A movable article-picking-up means which operates for the article-push-out means of each of the article-storing columns at position opposite to it is provided. The article pushed out by the movement of the article-push-out means actuated by the article-picking-up means is taken into the article-picking-up means and carried to a article-take-out unit of the machine. Further, a plurality of article-storing columns, each of which stores therein various kinds of articles piled up and being different from others, are arranged within a machine in row and column directions. An article-picking-up means, which takes in an article in each of the article-storing columns at the position opposite to it, is provided in a state being able to move in a perpendicular direction Y and in a horizontal direction X by a first and a second transfer means. The article taken into the article-picking-up means is carried to a article-take-out unit of the machine.
摘要:
A control circuit of a transportable crusher supplies, by the same pump, a required flow rate to hydraulic motors and actuators for a plurality of operating devices having different loads and improves simultaneous operability, fine adjustment, and reproducibility. The control circuit includes at least one variable displacement hydraulic pump (1) for supplying a hydraulic fluid; switch valves (12, 13, 14, 15, 16, 17, 18, 19, 20, 21), for conducting and interrupting the hydraulic fluid from the hydraulic pump (1) to the hydraulic motors and actuators (25a, 26a, 27a, 28a, 29a, 30a, 31a, 32a, 33a, 34a); pressure compensation control valves (11), for inputting front and back pressures of the switch valves, for controlling a discharge flow rate of the hydraulic pump (1) so that the difference of the front and back pressures can become constant and for distributing the discharge flow rate in accordance with a required power of the respective hydraulic motors and actuators or in accordance with a predetermined priority when the switch valves are simultaneously operated; and a controller (41), for controlling the switch valves to a predetermined value set in accordance with the load of the hydraulic motors and actuators.
摘要:
A self-propelling crushing machine is constructed by mounting a hopper (11) and a crusher (8) connected to said hopper on a vehicle body (1) having a traveling device (19), wherein a bottom plate (51) of said hopper (11) is designed for reciprocal motion in a horizontal direction relative to a charge inlet (8b) of said crusher. The bottom plate (51) receives an object of crush and then feeds into the charge inlet (8b) of the crusher (8) by reciprocal motion of the bottom plate to drop into the latter. Therefore, even when the weight of the object of crush or the charge amount of the object of crush into the hopper fluctuates, a substantially constant amount of object of crush can be fed into the crusher.
摘要:
A simple and efficient tool exchanger device is presented. The device has a pair of swing arms (8, 9), and each swing arm is provided with a set of grippers (11, 12) for holding a tool bit. The positions of the swing arms (8, 9) are separated by 90 degree so that they will not interfere with each other during the swinging motion. One driving device (2) is provided to operate both swing arms (8, 9) and operate the gripper devices (11, 12). The swing arm (8) rotates upwards to remove a used tool bit (10) from the machining shaft (21) of a machining center and the other swing arm (9) is rotated downwards to install a new tool bit (10') in the vacated machining shaft in a single simultaneous step.
