[0002] Straw crushing is a process in which the remaining straw after crop harvesting is cut and crushed by special equipment. In order to improve the crushing efficiency and prevent equipment failure due to material blockage, the application of anti-blocking feeding device in straw crushing is to ensure the stable operation of the equipment.

[0003] After searching, the announcement number is CN221228297U, and the name is a kind of anti-blocking feeding device for straw crusher, including a main body. Through research and analysis, it is found that although the utility model installs the device at the feeding inlet of the crusher and feeds the straw from the feeding inlet, the straw will enter the connecting barrel along the feeding inlet and then enter the inside of the main body. At this time, you can check whether the straw fed in can operate normally. If it can, there is no need to adjust the telescopic plate. If not, you can pull the handle to move the slide plate inside the slide. At this time, the telescopic plate will move to make the feeding space change a little, so that the straw can enter smoothly. However, to a certain extent, there are still the following disadvantages.

[0004] For example, the device does not have the function of segmented processing, and blockage and uneven crushing increase the power consumption of the crusher. At the same time, the wear of mechanical parts will also be accelerated, which will greatly increase the maintenance cost and the cost of replacing parts, and reduce the overall practicality of the device. In order to solve the above technical problems, we have designed an anti-blocking feeding device for straw crusher. Utility Model Content

The surface of the displacement rod 303 is fixedly connected to the inner cavity of the rectangular frame 1 with a mounting plate 305. The crushing teeth 306 are fixedly installed on the surface of the mounting plate 305. An empty groove 307 is provided on the surface of the crushing teeth 306. By providing the empty groove 307, the installation material of the crushing teeth 306 can be reduced, and the pre-separation effect can be achieved synchronously. The bottom of the rectangular frame 1 is connected to the collecting bucket 4. The inner cavity of the collecting bucket 4 is installed with a conveying and separating component 5. The conveying and separating component 5 includes a motor 501. The output end of the motor 501 is fixedly installed with a rotating rod 502. The surface of the rotating rod 502 is fixedly connected with a spiral steel sheet 503.

[0021] See also Figure 1 and Figure 3 The surface of the hydraulic cylinder 301 is bolted to the back surface of the rectangular frame 1, and the end of the rotating plate 302 away from the output end of the hydraulic cylinder 301 is rotatably connected to the surface of the fixed plate 304 through a rotating shaft;

[0022] See also Figure 1 and Figure 3 , the number of displacement rods 303 is several, and the right end of the displacement rod 303 passes through the rectangular frame 1;

[0023] See also Figure 1 and Figure 3 , displacement holes 308 are opened on both the left and right sides of the rectangular frame 1, and the surface of the displacement rod 303 is used in conjunction with the displacement hole 308;

[0024] See also Figure 1 、 Figure 2 and Figure 4 The motor 501 is located in the inner cavity of the collecting bucket 4, and a partition 2 is fixedly installed at the center of the inner cavity of the rectangular frame 1. By setting the partition 2, it can be used in conjunction with the crushing teeth 306 to pre-separate the straw, which is convenient for subsequent straw crushing processing and meets the fixed installation requirements of the motor 501. The top of the motor 501 is bolted to the bottom of the partition 2;

[0025] See also Figure 1 、 Figure 2 and Figure 4 The outer surface of the motor 501 is covered with a protective sleeve 504, which is used in conjunction with the motor 501. The top of the protective sleeve 504 is fixedly connected to the bottom of the partition 2. By providing the protective sleeve 504, the motor 501 can be protected from being exposed to the outside world for a long time, thereby increasing the service life of the motor 501.

[0026] See also Figure 4 The inner wall of the collecting bucket 4 is fixedly connected to the fixing rod 505, and the bottom end of the rotating rod 502 passes through the fixing rod 505 and is movably connected to the fixing rod 505. By providing the fixing rod 505, the connection between the collecting bucket 4 and the rotating rod 502 can be stably connected, thereby increasing the rotation stability of the rotating rod 502;

[0027] In practical application, the spiral steel blade 503 with a suitable pitch can be flexibly selected according to the average height of the straw to be processed;

[0028] In actual application, the two-stage design of the pressure pre-division component 3 and the conveying and separating component 5 can not only cope with thicker and larger straws well, but also reduce the damage rate of the contact between the components and the straw, ensuring the overall service life. At the same time, when a single component is damaged, it can be replaced separately. It has the characteristics of assembly and is more in line with actual use needs.

[0029] When in use, all components are in the initial state. When the straw needs to be crushed, the straw to be processed is placed vertically into the inner cavity of the rectangular frame 1, and the hydraulic cylinder 301 is controlled to work. The output end of the hydraulic cylinder 301 drives the rotating plate 302 to move backward, so that the end of the rotating plate 302 away from the output end of the hydraulic cylinder 301 pushes the displacement rod 303 and the fixed plate 304 to move relative to each other, and the crushing teeth 306 pre-divide the longer straws. Then the motor 501 is controlled to work, and the output end of the motor 501 drives the rotating rod 502 and the spiral steel sheet 503 to rotate synchronously. Since the straw is a straight material, as the straw gradually moves downward, it will contact the arc surface of the spiral steel sheet 503, and the upper end of the straw is pressed against the crushing teeth 306 to prevent it from falling off. As the spiral steel sheet 503 rotates, it will generate torque on the bottom end of the straw, breaking the pre-divided long straw into multiple short straws, effectively avoiding straw transmission blockage and facilitating the subsequent crushing process in the straw crusher.

[0030] To sum up: the straw crusher uses an anti-blocking feeding device, which solves the problem that the device does not have the function of segmented processing by setting a pressure pre-division component 3 and a conveying separation component 5. Blockage and uneven crushing increase the power consumption of the crusher, and at the same time, the wear of mechanical parts will also be accelerated, greatly increasing the maintenance cost and the cost of replacing parts, and reducing the overall practicality of the device.
