[0023] Technical effects and advantages of the present invention:

[0024] 1. The present invention adopts a protective crushing component, which drives the first electric cylinder through the controller to make the sleeve block drive the main distance sensor to move right, accurately detect the distance behind the mushroom stick, and the reduction motor drives the sleeve strip to carry the side distance sensor to rotate along the guide groove and the arc groove. The side distance sensor performs arc path detection on the left end face of the mushroom stick, and the other side distance sensor performs arc path detection on the right end face of the mushroom stick. When the detection values ​​of the main distance sensor and the two side distance sensors are within the preset range of the controller, it is confirmed that the target is a qualified mushroom stick, and the mushroom stick will be allowed to enter the crushing box for crushing. Through multi-point dynamic detection in three-dimensional space, accurate identification of the mushroom stick is achieved, and other foreign objects input are effectively intercepted to ensure that the input materials are mushroom sticks before entering to achieve crushing, greatly improving the safety and protection during crushing.

[0025] 2. When the present invention determines that the feed is a mushroom stick, the controller starts the second electric cylinder, so that the connecting block synchronously drives the proximity sensor and the concave plate to move downward. The concave plate causes the positioning plate and the two end blocks to move downward along the inside of the feed hopper and completely disengage, thereby removing the obstruction to the mushroom sticks and allowing the mushroom sticks to fall smoothly into the crushing box. When the proximity sensor detects the inclined surface of the inclined plate, the second electric cylinder reversely drives the connecting block to reset, and the positioning plate and the end blocks return to the feed hopper to form a protective barrier, realizing automatic switching from discharge to protection, which not only ensures the accurate feeding of mushroom sticks, but also avoids foreign objects or hands from accidentally entering, greatly improving the safety and continuity of the crushing operation.

[0026] In summary, through the interaction of the above multiple effects, first, the sleeve block drives the main distance sensor to move right, accurately detecting the distance to the rear of the mushroom stick. The side distance sensor performs arc path detection on the left end face of the mushroom stick. Another side distance sensor performs arc path detection on the right end face of the mushroom stick. When the detection values ​​of the main distance sensor and the two side distance sensors are within the preset range of the controller, the target is confirmed to be a qualified mushroom stick. Secondly, the concave plate causes the positioning plate and the two end blocks to move down along the inside of the feed hopper and completely disengage, allowing the mushroom stick to fall smoothly into the crushing box. In summary, the multi-point dynamic detection in three-dimensional space realizes the accurate identification of mushroom sticks, which not only ensures the accurate feeding of mushroom sticks, but also prevents foreign objects or hands from accidentally entering, greatly improving the safety protection during crushing.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figure 1 - Figure 8A screening-type edible mushroom stick crushing device is shown, and a protective crushing component is provided on the screening-type edible mushroom stick crushing device. The setting of the protective crushing component can realize multi-point dynamic detection in three-dimensional space, thereby realizing accurate identification of the mushroom sticks 21, ensuring accurate feeding of the mushroom sticks 21, and avoiding foreign objects or hands from accidentally entering, thereby greatly improving the safety protection during crushing. The specific structural setting of the protective crushing component is as follows.

[0038] In this embodiment, if Figure 1 - Figure 7 As shown, a crushing tooth roller 2 for crushing is rotatably installed on the inner wall of the crushing box 1, and a feed hopper 3 is fixedly connected to one end of the crushing box 1. The inner wall of the feed hopper 3 is provided with a protective crushing assembly, which includes: a positioning plate 4, which is installed inside the feed hopper 3, and a first electric cylinder 5 is installed on one side of the inner wall of the positioning plate 4; a sleeve block 6, which is fixedly connected to the pushing end of the first electric cylinder 5, and the sleeve block 6 is slidably connected to the positioning plate 4, and a main distance sensor 7 is fixedly connected to the inner wall of the sleeve block 6, and the main distance sensor 7 and the first electric cylinder 5 are both electrically connected to the controller 20, and both ends of the positioning plate 4 are fixedly connected to the end block 8; an arc groove 9, which is opened on the inner wall of the end block 8, and a side distance sensor 10 is installed on the inner wall of the arc groove 9, and a sleeve strip 11 is fixedly connected to the outer wall of the side distance sensor 10; a reduction motor 12, which is fixedly installed on one side of the inner wall of the end block 8, and the reduction motor 12 is used to drive the sleeve strip 11 to rotate inside the arc groove 9. The sleeve bar 11 is slidably connected to the end block 8. The output end of the reduction motor 12 is fixedly connected to the sleeve bar 11, and the reduction motor 12 is electrically connected to the controller 20. To facilitate the output end of the first electric cylinder 5 pushing the sleeve block 6 to the right, the main distance sensor 7 senses the distance to the rear of the mushroom stick 21. When the distance values ​​sensed by the main distance sensor 7 to the rear of the mushroom stick 21 are all within the distance value range set by the controller 20, the two reduction motors 12 respectively drive the two sleeve bars 11 to rotate clockwise. The sleeve bars 11 drive the side distance sensor 10 to rotate clockwise, and the side distance sensor 10 senses the distance of the left end surface of the mushroom stick 21 along an arc path. At the same time, another side distance sensor 10 performs arc path distance sensing on the right end face of the mushroom stick 21. When the distance values ​​sensed by the main distance sensor 7 and the two side distance sensors 10 are all within the distance value range set by the controller 20, the second electric cylinder 18 can be immediately started by the controller 20 to form a three-dimensional dimension verification. Only when the distance data of all points are in line with the preset range of the controller 20, the target is confirmed to be the mushroom stick 21.

[0039] In this embodiment, if Figure 5 - Figure 6As shown, a groove body 13 is provided on the outer wall of the sleeve block 6, and the sleeve block 6 is slidably connected to the positioning plate 4 to which the groove body 13 belongs. A guide groove 14 is provided on one side of the arc groove 9, and the sleeve strip 11 is slidably connected to the guide groove 14, so that the sleeve block 6 is guided to move right along the inner wall of the groove body 13 to realize the guiding operation of the sleeve block 6, and the sleeve strip 11 rotates clockwise along the guide groove 14 and the arc groove 9 to ensure that the sleeve strip 11 can stably move.

[0040] In this embodiment, if Figure 8 As shown, the bottom end of the positioning plate 4 is fixedly connected to a concave plate 15, which is slidably connected to the feed hopper 3. A connecting block 16 is fixedly mounted on the outer wall of the concave plate 15. A proximity sensor 17 is fixedly mounted on the lower surface of the connecting block 16 and is electrically connected to a controller 20. A second electric cylinder 18 is mounted on the upper inclined surface of the connecting block 16 and is used to push the connecting block 16. The outer wall of the second electric cylinder 18 is fixedly connected to the feed hopper 3. A sloping plate 19 is located below the proximity sensor 17 and is fixedly connected to the crushing chamber 1. The controller 20 is fixedly connected to the outer wall of the crushing chamber 1 and is electrically connected to the second electric cylinder 18. The outer wall of the concave plate 15 and the inner wall of the feed hopper 3 are both smooth surfaces. The pushing end of the second electric cylinder 18 is fixedly connected to the connecting block 16, and the sensing end surface of the proximity sensor 17 is arranged parallel to the upper inclined surface of the sloping plate 19. So that the output end of the second electric cylinder 18 drives the connecting block 16 to move downward, the connecting block 16 drives the proximity sensor 17 and the concave plate 15 to move downward synchronously, the concave plate 15 drives the positioning plate 4 to move downward through the feed hopper 3, and the positioning plate 4 drives the two end blocks 8 to move downward along the inside of the feed hopper 3. When the proximity sensor 17 senses the inclined surface on the inclined plate 19, the second electric cylinder 18 drives the connecting block 16 to move upward, so that the concave plate 15 drives the positioning plate 4 to move upward into the inside of the feed hopper 3, and at the same time, the two end blocks 8 enter the inside of the feed hopper 3.

[0041] In this embodiment, if Figure 3 As shown, a mushroom stick 21 is placed between the two end blocks 8. One end of each end block 8 is slidably connected to a guide plate 22, which is used to guide the movement of the mushroom stick 21. The lower surfaces of the two guide plates 22 are fixedly connected to the feed hopper 3. This allows the mushroom stick 21 to be guided along the two guide plates 22 to enter the position between the two end blocks 8, thereby achieving the guiding operation.

[0042] In this embodiment, if Figure 3 As shown, a spacer plate 23 is provided above the positioning plate 4, and a housing 24 is fixedly connected to the upper surface of the spacer plate 23. The housing 24 is fixedly connected to the feed hopper 3. The housing 24 supports the spacer plate 23, and a gap is provided between the spacer plate 23 and the positioning plate 4 to prevent the operator's hands from entering the crushing box 1 when feeding materials.

[0043] In this embodiment, if Figure 1 As shown, the crushing roller 2 is provided with multiple screening columns 25 on the outside. The multiple screening columns 25 are arranged equidistantly around the circumference, with gaps between adjacent screening columns 25. This allows the crushed particles to be screened through the gaps between the adjacent screening columns 25, preventing larger lumps from being discharged and ensuring a fully effective crushing operation.

[0044] In this embodiment, if Figure 1 As shown, a motor 26 is installed at one end of the crushing tooth roller 2, and the motor 26 is used to drive the crushing tooth roller 2 to rotate inside the crushing box 1. A support block 27 is fixedly connected to the lower surface of the motor 26, and the support block 27 is fixedly connected to the crushing box 1. The support block 27 is used to support the motor 26 so that the motor 26 starts the crushing tooth roller 2 to rotate inside the crushing box 1, and the support block 27 stably supports the motor 26, increases the stability of the motor 26, and ensures that the crushing tooth roller 2 drives the mushroom stick 21 to achieve the crushing operation.

[0045] The working principle of the screening type edible mushroom stick crushing device of the present invention is as follows:

[0046] First, when the present invention performs guided loading, the mushroom stick 21 is guided and placed between the two guide plates 22, and guided along the two guide plates 22 to the position between the two end blocks 8. At the same time, the rear of the mushroom stick 21 is located in the front position of the positioning plate 4. In this way, the mushroom stick 21 is positioned and guided to be placed, completing the loading operation of the mushroom stick 21.

[0047] Secondly, when the present invention performs protective crushing detection, the first electric cylinder 5 is started by the controller 20, and the output end of the first electric cylinder 5 pushes the sleeve block 6 to move right. The sleeve block 6 moves right along the inner wall of the trough body 13, and the sleeve block 6 drives the main distance sensor 7 to move right. The main distance sensor 7 senses the moving distance behind the mushroom stick 21. When the distance value sensed by the main distance sensor 7 to the rear of the mushroom stick 21 is within the distance value range set by the controller 20.

[0048] At the same time, the positioning plate 4 supports the end block 8, which in turn supports the reduction motor 12. The controller 20 activates the two reduction motors 12, which in turn drive the two sleeve bars 11 to rotate clockwise. The sleeve bars 11 rotate clockwise along the guide slots 14 and the arcuate slots 9. Furthermore, the sleeve bars 11 drive the side distance sensor 10 to rotate clockwise, which senses the distance of the left end face of the mushroom stick 21 along an arcuate path. Simultaneously, another side distance sensor 10 senses the distance of the right end face of the mushroom stick 21 along an arcuate path. When the distance values ​​sensed by both side distance sensors 10 are within the distance range set by the controller 20, and thus the distance values ​​sensed by the main distance sensor 7 and the two side distance sensors 10 are all within the distance range set by the controller 20, the controller 20 immediately activates the second electric cylinder 18, thereby determining that the mushroom stick 21 is located in front of the positioning plate 4 and between the two end blocks 8.

[0049] Then, when the present invention performs protective crushing linkage, it is determined that it is a mushroom stick 21, and the second electric cylinder 18 is started through the controller 20, and the feed hopper 3 supports the second electric cylinder 18 at the same time. In this way, the output end of the second electric cylinder 18 drives the connecting block 16 to move downward, and the connecting block 16 drives the proximity sensor 17 to move downward, and the connecting block 16 drives the concave plate 15 to move downward at the same time, and the concave plate 15 drives the positioning plate 4 to pass through the feed hopper 3 and move downward, and the positioning plate 4 drives the two end blocks 8 to move downward along the inside of the feed hopper 3, so that the positioning plate 4 and the two end blocks 8 all move downward and are no longer located inside the feed hopper 3. At the same time, the connecting block 16 drives the proximity sensor 17 to move downward. At this time, the positioning plate 4 and the two end blocks 8 all move downward out of the inside of the feed hopper 3, and at the same time, the positioning plate 4 no longer blocks the mushroom stick 21. The mushroom stick 21 enters the crushing box 1 along the inside of the feed hopper 3 under the action of gravity. When the proximity sensor 17 senses the inclined surface on the inclined plate 19, the second electric cylinder 18 drives the connecting block 16 to move upward, the connecting block 16 drives the concave plate 15 to move upward, the concave plate 15 drives the positioning plate 4 to move upward into the feed hopper 3, and at the same time the positioning plate 4 drives the two end blocks 8 to enter the feed hopper 3, continuing to perform safety protection and continue to judge the next mushroom stick 21.

[0050] Finally, when the present invention performs a crushing operation, the mushroom sticks 21 inside the crushing box 1 start the motor 26 through the controller 20, and the motor 26 starts the crushing tooth roller 2 to rotate inside the crushing box 1. At the same time, the crushing box 1 supports the support block 27, and the support block 27 supports the motor 26 to increase the stability of the motor 26. The crushing tooth roller 2 drives the mushroom sticks 21 to perform a crushing operation. After crushing, the mushroom sticks 21 are screened through multiple gaps adjacent to multiple screening columns 25. The fine particles screened by the mushroom sticks 21 are discharged through the gaps, and the larger blocks will continue to be crushed on the crushing tooth roller 2, thus completing the screening and crushing operation.

In this technical solution, the electrical control components not mentioned are not shown in the figure because they belong to the existing technology and are not described here.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
