DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The straw to be crushed can be directly put into the feeding hopper 105, and the straw will enter the crushing box 104 along the feeding hopper 105. The output wheel 107 can be driven to rotate by the driving motor 106. The output wheel 107 causes the driven wheel 111 to rotate through the transmission belt 108, thereby rotating the second rotating shaft 110. Since the gears 112 on the outer sides of the first rotating shaft 109 and the second rotating shaft 110 are meshed with each other, the first rotating shaft 109 and the second rotating shaft 110 can rotate together. With the help of the crushing blocks 113 on the outer sides of the first rotating shaft 109 and the second rotating shaft 110, the straw can be crushed. During the crushing process, the straw can also be driven downward by the unloading unit to make The lighter straw is easier to enter between the crushing blocks 113 to realize the crushing operation. The crushed straw will fall into the extrusion box 103. With the help of the extrusion unit, the straw at the bottom of the extrusion box 103 can be squeezed to make the straw fragments squeezed into blocks, which can effectively reduce the space occupied by the straw fragments. After the straw fragments are extruded and formed, the straw fragments can be pushed out of the extrusion box 103 through the discharge unit. It is very convenient to use. The crushing machine can quickly deliver the straw to the crushing blocks 113 for crushing operation, effectively improving the crushing efficiency. At the same time, it can effectively reduce the space occupied by the crushed straw fragments, making it more convenient for subsequent transportation and processing, and having a better use effect.

[0032] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5The unloading unit includes a telescopic cylinder 201 fixedly arranged on the outer wall of the feeding hopper 105, a circular plate 202 is fixedly installed on the telescopic end of the telescopic cylinder 201, a vertical rod 203 is fixedly installed on the top of the circular plate 202, a movable plate 206 is sleeved on the outer side of the vertical rod 203, and a lower pressure plate 208 is fixedly installed on the lower surface of the movable plate 206, the lower pressure plate 208 penetrates the feeding hopper 105, and the lower pressure plate 208 is located in the middle position of the crushing box 104, a first spring 205 is sleeved on the outer side of the vertical rod 203, and one end of the first spring 205 is connected to the lower surface of the movable plate 206, The other end of the first spring 205 is connected to the upper surface of the circular plate 202, the top of the vertical rod 203 is fixedly connected with the top plate 204, the upper surface of the movable plate 206 is also fixedly installed with a touch switch 207, the inner wall of the crushing box 104 is also fixedly installed with a guide plate 209, the adjacent guide plates 209 are V-shaped, and the lower pressure plate 208 is located between the guide plates 209. Under the action of the guide plates 209, the straw can be more easily entered between the crushing blocks 113. The outer side of the lower pressure plate 208 is also provided with a side pressure component for laterally pressing the straw downward. The outer side of the feeding hopper 105 is also A warning component is provided to remind the staff to perform the feeding operation in time. When the straw is put into the feeding hopper 105, the circular plate 202 can be driven to move up and down by the telescopic cylinder 201. When the circular plate 202 moves downward, the first spring 205 above the circular plate 202 will pull the moving plate 206 to move downward, thereby driving the lower pressing plate 208 to move downward together. The bottom end of the lower pressing plate 208 can press the straw down to between the crushing blocks 113, so that the crushing blocks 113 can quickly crush the straw. The feeding unit can crush the quality by realizing the cyclic reciprocating motion of the lower pressing plate 208. Lighter straw is quickly fed into the crushing blocks 113 for crushing operation, which effectively improves the crushing efficiency. Furthermore, when the lower pressure plate 208 presses down the straw, it will also cause the first spring 205 to be stretched until the touch switch 207 above the movable plate 206 contacts the lower surface of the top plate 204, which can prompt the telescopic cylinder 201 to drive the circular plate 202 to move upward to ensure that the downward pressure applied by the lower pressure plate 208 on the straw is moderate, so that only an appropriate amount of straw enters between the crushing blocks 113, effectively avoiding the occurrence of jams caused by excessive pressure, and achieving better use effect.

When the lower pressure plate 208 moves downward, the side pressure plate 303 in the inclined groove 301 will contact the straw and cause the side pressure plate 303 to expand to both sides, which can more effectively press down the straw. When the lower pressure plate 208 moves upward, the side pressure plate 303 will automatically retract into the inclined groove 301, and will not affect the upward movement of the lower pressure plate 208.

[0034] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The warning component includes a support plate 401 fixedly arranged on the side wall of the feeding hopper 105, and a touch switch 402 is fixedly installed on the upper surface of the support plate 401, and the touch switch 402 is located below the movable plate 206. An alarm 403 is fixedly installed on the outer wall of the crushing box 104, and the touch switch 402 is electrically connected to the controller, and the controller and the alarm 403 are electrically connected. When the movable plate 206 moves downward and contacts the touch switch 402 above the support plate 401, it indicates that there is not much straw to be crushed in the feeding hopper 105 at this time. At this time, the triggered touch switch 402 can control the alarm 403 to sound an alarm through the controller, reminding the staff to perform the feeding operation in time. Furthermore, the support plate 401 can also play a role in blocking the movable plate 206 from continuing to move downward, so as to avoid the end of the lower pressure plate 208 from entering between the crushing blocks 113 and causing damage, and the use effect is better.

[0035] As an embodiment of the present invention, please refer to Figure 2 and Fig. 9 The extrusion unit includes a support rod 501 fixedly arranged in the extrusion box 103, a hydraulic cylinder 502 is fixedly installed at the end of the support rod 501, and an extrusion block 503 is fixedly installed at the telescopic end of the hydraulic cylinder 502, and the extrusion block 503 cooperates with the inner wall of the extrusion box 103. When the hydraulic cylinder 502 drives the extrusion block 503 to move upward, the straw fragments in the extrusion box 103 will fall to the bottom of the extrusion box 103 through the gap between the extrusion box 103 and the extrusion block 503. When the hydraulic cylinder 502 drives the extrusion block 503 to move downward, the straw fragments at the bottom of the extrusion box 103 can be squeezed, which is very convenient to use.

[0036] As an embodiment of the present invention, please refer to Figure 2 , Figure 7 , Figure 8 and Fig. 9The pushing unit includes a pushing port 601 and a discharging port 602 symmetrically opened on both sides of the extrusion box 103, a pushing plate 603 is movably installed in the pushing port 601, a blocking frame 604 is fixedly installed on the outer wall of the extrusion box 103 for blocking the pushing plate 603, a side rod 605 is fixedly installed on the outer wall of the pushing plate 603 away from the extrusion box 103, and a blocking piece 606 is fixedly installed on the end of the side rod 605, an electric telescopic rod 608 is fixedly installed below the bracket 102, and a push-pull plate 609 is fixedly installed on the telescopic end of the electric telescopic rod 608, the push-pull plate 609 is sleeved on the outer side of the side rod 605, and a second spring 607 is also sleeved on the outer side of the side rod 605, one end of the second spring 607 is connected to the blocking piece 606, and the other end of the second spring 607 is connected to the push-pull plate 609, and the outer wall of the extrusion box 103 is also provided with a blocking component for sealing the discharging port 603. 02. When the straw fragments at the bottom of the extrusion box 103 are squeezed, the blocking assembly for the discharge port 602 can be released first, and then the push-pull plate 609 can be driven to move by the electric telescopic rod 608 until the push-pull plate 609 contacts the push plate 603, and the push-pull plate 609 can push the push plate 603 to move, so that the push plate 603 pushes the straw fragments out of the discharge port 602. After the straw fragments are pushed out, the push-pull plate 609 can be moved back by the contraction of the electric telescopic rod 608 until the push plate 603 re-enters the push port 601. As the push-pull plate 609 moves further, the second spring 607 can be compressed, and the push plate 603 will be in a state of being in contact with the baffle frame 604, ensuring that the push plate 603 completely enters the push port 601, and will not hinder the subsequent downward movement of the extrusion block 503, thereby achieving a better use effect.

[0037] As an embodiment of the present invention, please refer to Figure 2 , Figure 7 , Figure 8 and Fig. 9 The sealing assembly includes a rotating plate 701 rotatably arranged on the outside of the extrusion box 103, and a sealing plate 702 is fixedly installed on the outer wall of the rotating plate 701 close to the extrusion box 103, and the sealing plate 702 is located in the discharge port 602.

When discharging is required, the sealing strip 704 is directly driven to move up by the electric telescopic rod 703, so as to release the limit on the rotating plate 701. When the straw crushed blocks move toward the discharge port 602, the rotating plate 701 can be automatically lifted up to realize the discharge of the straw crushed blocks, which is very convenient to use.

[0038] When in use, the straw to be crushed can be directly put into the feeding hopper 105, and the straw will enter the crushing box 104 along the feeding hopper 105. The output wheel 107 can be driven to rotate by the driving motor 106.

Since the gears 112 on the outside of the first rotating shaft 109 and the second rotating shaft 110 are meshed with each other, the first rotating shaft 109 and the second rotating shaft 110 can be rotated together. With the help of the crushing blocks 113 on the outside of the first rotating shaft 109 and the second rotating shaft 110, the straw crushing operation can be realized.
