[0025] The following further describes the present utility model in detail with reference to the accompanying drawings of the specification and specific embodiments.

[0026] Figures 1 to 3 An embodiment of the crawler type grain counting machine of the present utility model is shown. The crawler type grain counting machine of this embodiment includes a frame 1, a circulating conveyor belt 2 provided on the frame 1, and a blanking port 3 provided below the corner of the circulating conveyor belt 2. A plurality of bins 21 are provided on the circulating conveyor belt 2. A floating guard plate 4 is provided above the corner of the circulating conveyor belt 2. The floating guard plate 4 is hinged to the frame 1. A flexible pressing member 5 is provided on the frame 1. One end of the flexible pressing member 5 abuts against the floating guard plate 4 to make the floating guard plate 4 approach the circulating conveyor belt 2. In this embodiment, the circulating conveyor belt 2 generally presents a triangular structure and operates in a clockwise direction. The blanking port 3 is located at the lower right of the circulating conveyor belt 2, and the floating guard plate 4 is located at the upper right of the circulating conveyor belt 2. The flexible pressing member 5 includes a pipe whose flexibility is adjusted by the air pressure.

[0027] In the crawler - type granule - counting machine of this embodiment, a floating guard plate 4 is provided above the corner of the circulating conveyor belt 2. The floating guard plate 4 is hinged to the frame 1, and at the same time, a flexible pressing member 5 applies pressure to the floating guard plate 4, making the floating guard plate 4 close to the circulating conveyor belt 2 (of course, the gravity of the floating guard plate 4 itself also plays a role in making it close to the circulating conveyor belt 2), which is beneficial to preventing the medicine granules in the bin 21 from being thrown out at the corner and improving the granule - counting accuracy. Compared with the guard plate fixedly installed on the frame 1, the floating guard plate 4 is beneficial to preventing rigid collision with the medicine granules, resulting in damage to the medicine granules, and has a simple and reliable structure. And by adjusting the air pressure inside the pipe, the flexibility of the pipe can be adjusted, and then the pressure applied to the floating guard plate 4 can be adjusted, with good adaptability, convenient adjustment, and avoiding frequent replacement.

[0028] Further, in this embodiment, the flexible pressing member 5 includes a hose 52, and the inside of the hose 52 is filled with air and the inflation pressure is adjustable. By adjusting the inflation pressure inside the hose 52, the pressure applied by the hose 52 to the floating guard plate 4 can be adjusted, with good adaptability, convenient adjustment, and avoiding frequent replacement.

[0029] Further, in this embodiment, an air - source component 51 is provided on the frame 1, and the other end of the hose 52 is communicated with the air - source component 51. Specifically, referring to Figure 1 and 3 , since the width of the circulating conveyor belt 2 is relatively large, a plurality of bins 21 are provided along the width direction. Correspondingly, a plurality of floating guard plates 4 and hoses 52 are also provided. Setting the air - source component 51 on the frame 1 facilitates simultaneously adjusting the inflation pressure inside each hose 52.

[0030] Further, in this embodiment, a plurality of connecting parts 41 are provided on the floating guard plate 4, and one end of the hose 52 is detachably connected to the connecting part 41. The distances from different connecting parts 41 to the rotation center of the floating guard plate 4 are different. By adjusting the connection of the hose 52 to different connecting parts 41, the magnitude of the rotational torque applied to the floating guard plate 4 can be adjusted, making it more convenient to use.

[0031] Specifically, referring to Figure 3 , in this embodiment, the connecting part 41 is a threaded hole, and one end of the hose 52 is provided with a threaded joint 521 that mates with the threaded hole. The hose 52 and the floating guard plate 4 are connected by threads, with good connection reliability and convenient disassembly, installation, and maintenance.

[0032] Further, in this embodiment, a support rod 11 is provided on the frame 1, and an installation hole 42 is provided on the floating guard plate 4. The support rod 11 passes through the installation hole 42, that is, realizing the hinged connection between each floating guard plate 4 and the frame 1, with a simple and reliable structure.

[0033] Furthermore, in this embodiment, there is a gap between the support rod 11 and the installation hole 42, which is beneficial to realizing the relative rotation of the floating guard plate 4 with respect to the frame 1.

[0034] As a preferred embodiment, a sprocket mechanism 6 is provided on the frame 1, and the circulating conveyor belt 2 is connected to the sprocket mechanism 6. The circulating conveyor belt 2 can be driven by the sprocket mechanism 6 to circulate. By adopting the sprocket mechanism 6, the transmission reliability is good. Of course, in other embodiments, the circulating conveyor belt 2 can also be circulated by other means such as a synchronous belt.

[0035] As a preferred embodiment, the pipe is of a bent structure. See specifically Figure 3 , compared with a straight pipe, the pipe with a bent structure can apply a better force to the floating guard plate 4.

[0036] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the technical content disclosed above, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
