Description

Technical Field

[0001] This utility model relates to the field of straw returning machine technology, specifically a debris blocking device for a straw crushing and returning machine. Background Technology

[0002] A straw crushing and returning machine is an agricultural machine used to crush crop straw and evenly spread it on the surface of farmland. It mainly uses high-speed rotating blades to cut, tear, and crush the straw. During operation, power is transmitted to the cutter shaft through a transmission device, which drives the blades mounted on it to rotate at high speed. When the straw enters the machine's working area, it is chopped into small pieces by the blades, and then the crushed straw is evenly spread on the field by a spreading device.

[0003] Returning crushed straw to the field can increase the organic matter content of the soil. After decomposition, these organic substances loosen the soil, enhancing its aeration and water retention. For example, land where straw is returned to the field regularly shows improved soil aggregate structure, which is beneficial for crop root growth and development. However, when the machine crushes the straw, the internal blades rotate at high speeds, causing straw fragments to fly directly out of the discharge port, making it inconvenient for workers. Utility Model Content

[0004] The purpose of this invention is to provide a debris blocking device for a straw crushing and returning machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a debris blocking device for a straw crushing and returning machine, comprising a crushing device, a feed inlet fixedly connected to the top of the crushing device, a discharge outlet fixedly connected to the bottom of the crushing device, a blocking mechanism provided on the outside of the crushing device, a positioning mechanism provided on the outside of the blocking mechanism, and support legs fixedly connected to the front and rear sides of the crushing device above the blocking mechanism.

[0006] The blocking mechanism includes an interception component and a limiting component. The interception component is disposed on the outside of the crushing equipment, and the limiting component is disposed on the inside of the outside of the interception component.

[0007] The positioning mechanism includes a positioning component and an outer pull component. The positioning component is located outside the interception component, and the outer pull component is located inside the outside of the positioning component.

[0008] Preferably, the interception component includes a frame, which is slidably connected to the bottom of the outer ring of the crushing equipment, an interception mesh plate is fixedly connected to the inner side of the outer side of the frame, and handles are fixedly connected to the top of the left and right sides of the frame.

[0009] Preferably, the limiting component includes a movable slider, which is fixedly connected to the bottom of the four corners of the outer side of the crushing equipment. The movable slider is slidably connected to the inner side of the outer side of the frame. A limiting slider is fixedly connected to the outer side of the movable slider. A sleeve is sleeved around the outer ring of the limiting slider. The sleeve is fixedly connected to the outer side of the frame.

[0010] Preferably, the positioning component includes a fixed box, which is fixedly connected to the bottom of the outer side of the housing. A sliding plate is slidably connected inside the fixed box. A compression spring is fixedly connected to the outer side of the sliding plate. A locking block is fixedly connected to the inner side of the sliding plate. The locking block is engaged with the inner side of the limiting slider.

[0011] Preferably, the external pull assembly includes a telescopic slide rod, which is fixedly connected to the outside of the slide plate, sleeved on the inner ring of the compression spring, slidably connected to the inside of the fixed box, and a pull rod is fixedly connected to the outside of the telescopic slide rod.

[0012] Compared with the prior art, this utility model provides a debris blocking device for a straw crushing and returning machine, which has the following beneficial effects:

[0013] 1. The straw crushing and returning machine uses a debris blocking device. Through the setting of the blocking mechanism, when the device is in use, the sleeve frame and the intercepting net plate slide down to block the discharge port. When the discharge port discharges the crushed straw material, it comes into contact with the intercepting net plate and is blocked and controlled inside the intercepting net plate, so that the crushed straw will not scatter. At the same time, the operator only needs to pull the handles on the left and right sides to move the intercepting net plate up and down. The operation is simple and convenient for the operator to use.

[0014] 2. The straw crushing and returning machine uses a debris blocking device. Through a positioning mechanism, after the frame moves upward to its limit, the sliding plates at the four corners, under the action of compression springs, drive the locking blocks to move inward on their own. This locks the blocks onto the outside of the limiting slider, thus positioning the frame. When not in use, the frame can be fixed to the outside of the crushing equipment and will not slide downward on its own, thus not affecting the overall handling or maintenance of the device. At the same time, the operator only needs to pull the lever outward to release the positioning of the frame, allowing it to slide downward to protect the discharge port. The operation is simple and convenient for operators. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figures 1 to 6A debris blocking device for a straw crushing and returning machine includes a crushing device 3, a feed inlet 31 fixedly connected to the top of the crushing device 3, a discharge outlet 32 ​​fixedly connected to the bottom of the crushing device 3, a blocking mechanism 1 set on the outside of the crushing device 3, a positioning mechanism 2 set on the outside of the blocking mechanism 1, and support legs 4 fixedly connected to the front and rear sides of the crushing device 3 above the blocking mechanism 1.

[0028] The blocking mechanism 1 includes an interception component 11 and a limiting component 12. The interception component 11 is located outside the crushing equipment 3, and the limiting component 12 is located inside the outside of the interception component 11.

[0029] The interception component 11 includes a frame 1101, which is slidably connected to the bottom of the outer ring of the crushing device 3. An interception mesh plate 1102 is fixedly connected to the inner side of the outer side of the frame 1101. Handles 1103 are fixedly connected to the top of the left and right sides of the frame 1101. The limiting component 12 includes a movable slider 1201, which is fixedly connected to the bottom of the four corners of the outer side of the crushing device 3. The movable slider 1201 is slidably connected to the inner side of the outer side of the frame 1101. A limiting slider 1202 is fixedly connected to the outer side of the movable slider 1201. A shell 1203 is sleeved on the outer ring of the limiting slider 1202. The shell 1203 is fixedly connected to the outer side of the frame 1101.

[0030] Furthermore, when the device is in use, the sleeve frame 1101 and the intercepting net plate 1102 slide downwards to block the discharge port 32, so that when the discharge port 32 discharges the crushed straw material, it comes into contact with the intercepting net plate 1102 and is intercepted and controlled inside the intercepting net plate 1102, so that the crushed straw will not scatter. At the same time, the operator only needs to pull the handles 1103 on the left and right sides to move the intercepting net plate 1102 up and down, which is simple to operate and easy for the operator to use.

[0031] Example 2

[0032] See Figure 1 , Figure 3 , Figure 5 and Figure 6 Furthermore, based on Embodiment 1, the positioning mechanism 2 includes a positioning component 21 and an outer pull component 22. The positioning component 21 is disposed outside the interception component 11, and the outer pull component 22 is disposed inside the outer side of the positioning component 21.

[0033] The positioning component 21 includes a fixed box 2101, which is fixedly connected to the bottom outer side of the housing 1203. A sliding piece 2102 is slidably connected inside the fixed box 2101. A compression spring 2103 is fixedly connected to the outer side of the sliding piece 2102. A locking block 2104 is fixedly connected to the inner side of the sliding piece 2102. The locking block 2104 is engaged with the inner outer side of the limiting slider 1202. The external pulling component 22 includes a telescopic slide rod 2201, which is fixedly connected to the outer side of the sliding piece 2102. The telescopic slide rod 2201 is sleeved on the inner ring of the compression spring 2103. The telescopic slide rod 2201 is slidably connected to the inner outer side of the fixed box 2101. A pull rod 2202 is fixedly connected to the outer side of the telescopic slide rod 2201.

[0034] Furthermore: After the frame 1101 moves upward to its limit, the sliding plates 2102 at the four corners, under the action of the compression springs 2103, drive the locking blocks 2104 to move inward on their own, so that the locking blocks 2104 engage with the outer side of the limiting slider 1202 to complete the positioning of the frame 1101. This allows the frame 1101 to be fixed to the outside of the crushing equipment 3 when the device is not in use, preventing it from sliding downward on its own and thus not affecting the overall handling or maintenance of the device. At the same time, the operator only needs to pull the lever 2202 outward to release the positioning of the frame 1101, allowing the frame 1101 to slide downward to protect the discharge port 32. The operation is simple and convenient for operators to use.

[0035] In actual operation, when this device is used and needs to intercept the straw fragments splashing from the discharge port 32, the operator first pulls the four corner levers 2202 outward. The outward movement of the levers 2202 drives the locking block 2104 outward through the telescopic sliding rod 2201 and the sliding plate 2102. The locking block 2104 moves outward and retracts into the fixed box 2101, disengaging from the limiting slider 1202. Then, the frame 1101 and the intercepting net plate 1102 can slide downward under the action of gravity. At this time, the frame 1101 and the intercepting net plate 1102 are fitted onto the outside of the discharge port 32, thus completing the protection and interception of the discharge port 32.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
