DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: Reference Figure 1-6 The one shown comprises a material receiving trolley 1 with a push rod 2, a housing 18 with a hollow interior is fixed on the rear end of the material receiving trolley 1, and the two lower ends of the push rod 2 are slidably arranged with the housing 18;

[0029] Two U-shaped blocks 3 are installed at the front end of the material receiving trolley 1, and L-shaped plates 7 are fixed on the side walls of the two U-shaped blocks 3, and a locking spring 8 is fixed on the L-shaped plate 7, and the other end of the locking spring 8 is fixedly connected to a locking block 5 that penetrates the U-shaped block 3 and extends into the U-shaped cavity, and an extrusion slope 6 is provided at the front end of the locking block 5, and a pull rope 9 is fixed to the left end of the locking block 5, and the pull rope 9 passes through the axis of the locking spring 8 and sequentially passes through the L-shaped plate 7 and the housing 18 and is fixedly connected to the stopper 19 at the lower end of the hand push rod 2;

[0030] The first guide wheel 10 adapted to the pull rope 9 is fixed on the outer wall of the material receiving trolley 1 and the L-shaped plate 7;

[0031] It also includes a longitudinal adjustment unit for adjusting the distance between the two U-shaped blocks 3 and the material receiving trolley 1.

[0032] When in use, the material receiving trolley 1 can be directly pushed by the push rod 2 to move close to the crushing roller (at this time, the lower end of the push rod 2 and the rear end of the material receiving trolley form a conflict). When reaching the bottom of the crushing roller, as the material receiving trolley 1 moves, the conveyor support foot of the tablet pressing and crushing integrated machine and the extrusion inclined surface of the locking block 5 are squeezed, so that the tunnel block 5 moves close to the L-shaped plate 7, and finally the support foot moves into the limiting cavity surrounded by the U-shaped cavity and the locking block 5 (such as Figure 7 As shown in the figure), the material receiving trolley and the conveyor are fixed, and the material receiving trolley is fixed. When releasing the fixation of the material receiving trolley 1, the hand push rod 2 can be held and pulled outward, and the stopper 19 will drive the pull rope 9 to move, and the lock block 5 will compress the lock spring 8 through the pull rope 9. When the stopper 19 contacts the inner wall of the shell 18 to form a resistance, the lock block 5 releases the obstruction of the supporting foot, and the material receiving trolley 1 can be pulled to move. The fixation and release of the material receiving trolley 1 can be completed in the process of pushing and pulling the material receiving trolley 1, making the operation more convenient and quick.

[0033] A longitudinal adjustment unit is provided for adjusting the distance between the two U-shaped blocks 3 and the material receiving trolley 1 to meet the installation requirements and also to prevent the material blocks from falling and accumulating toward one side of the inner cavity of the material receiving trolley and causing the material receiving trolley 1 to overflow in advance.

[0034] As a preferred implementation in this embodiment, Figure 3 , Figure 4 and Figure 6 As shown, the longitudinal adjustment unit includes a slider 21 mounted on the rear end of the U-shaped block 3, a round block 20 adapted to the slider 21 and fixedly mounted on the front end of the material receiving trolley 1, and three second guide wheels 11 arranged in a V shape;

[0035] The slider 21 is slidably arranged in the rectangular cavity of the circular block 20, and the upper end of the circular block 20 is rotatably arranged with the first worm 12 and the screw 13, and the screw 13 is fixedly sleeved with the first worm wheel 14, and the first worm wheel 14 is meshed and connected with the first worm 12, and the screw 13 is threadedly sleeved with a threaded tube 16, and the side wall of the threaded tube 16 is fixed with a limit block 17, and the limit block 17 is slidably penetrated by the limit rod 15 fixed to the upper end of the circular block 20, and a second guide wheel 11 located at the tip is installed on the threaded tube 16, and the other second guide wheels 11 are installed on the front end of the material receiving trolley 1;

[0036] The inner cavity of the circular block 20 is coaxially rotatably provided with a second worm gear 25 and a driving gear 24. The second worm gear 25 is located above the driving gear 24. An opening 22 is provided on the slider 21, and a plurality of driving teeth 23 are provided in a straight line on the inner wall of the opening 22. The driving gear 24 is gear-engaged with the driving teeth 23. The second worm gear 25 is rotatably provided with a second worm 26 in meshing connection with the inner cavity of the circular block 20. The lower end of the first worm 12 extends to the inner cavity of the circular block 20 and is meshedly connected with the second worm 26 through a bevel gear.

[0037] During adjustment, the first worm 12 can be rotated to rotate the screw 13 and the second worm 26, and the threaded tube 16 drives a second guide wheel 11 to move outward. At the same time, the second worm 26 drives the second worm wheel 25 to rotate, thereby rotating the driving gear 24 and driving the slider 21 to move away from the material receiving trolley 1 through cooperation with the driving tooth 23, and finally adjusts the distance between the U-shaped block 3 and the front end of the material receiving trolley 1. During the entire adjustment process, the pull rope 9 is always kept taut, the first worm 12 is rotated in the opposite direction, the second guide wheel 11 moves inward, and the slider 21 moves closer to the material receiving trolley 1.

[0038] It should be noted that, first, the second worm 26 and the second worm wheel 25 can produce self-locking, that is, when the U-shaped block 3 is squeezed, its slider 21 cannot drive the second worm 26 to rotate through the second worm wheel 25; second, the lower end of the first worm 12 and the end near the lower end of the first worm 12 are provided with bevel gears, and the two bevel gears are meshingly connected.

[0039] As a preferred implementation in this embodiment, Figure 3 As shown, the front ends of the two U-shaped blocks 3 are connected to two guide plates 4 that are opened outwards, and the two guide plates 4 are arranged in an eight-shaped shape.

[0040] The guide plate 4 can adjust the positions of the material receiving trolley 1 and the support frame 1, thereby facilitating the docking installation of the material receiving trolley 1 and the support foot.

[0041] It should be noted that the surface of the guide plate 4 is set to be a smooth surface, which can reduce the friction between the guide plate 4 and the support feet and reduce the installation resistance of personnel.

[0042] As a preferred implementation in this embodiment, the angle between the two guide plates 4 and the horizontal line is 30° to 45°.

[0043] The angle between the two guide plates 4 and the horizontal line is set to 30° to 45°. If the angle is too large, it will easily lead to a smaller guiding range, that is, a smaller correction range. If the angle is too small, the operator needs to apply a larger thrust to complete the plug-in during installation, that is, it is laborious.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
