Technical Field

[0001] The present invention relates to the field of straw crushing devices, and more particularly to an automatic identification straw crushing device and method with a drying and forming structure. Background Art

[0002] Straw is the general term for the stems and leaves of mature crops. It typically refers to the remaining portion after the seeds are harvested from wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane, and other crops. More than half of the products of photosynthesis are found in straw. Rich in nitrogen, phosphorus, potassium, calcium, magnesium, and organic matter, straw is a versatile, renewable bioresource. It is also a form of roughage, characterized by its high crude fiber content and the presence of lignin. It can be crushed by a pulverizer to produce fertilizer, feed, and other materials.

[0003] Patent application number 202320718511.1 discloses an agricultural straw crushing device, including a straw crushing box, wherein a first crushing chamber and a second crushing chamber are sequentially provided in the straw crushing box, a feed pipe is fixedly installed through the upper end of the first crushing chamber, a circulation port is provided between the first crushing chamber and the second crushing chamber, a discharge port is provided at the lower end of the second crushing chamber, and a discharge pipe is fixedly installed at the lower end of the discharge port. This application is provided with a conical feed hopper, which can be used to conveniently feed materials. A sealing cover can prevent external impurities from directly entering the straw crushing box through the feed pipe when not in use. An external control device can drive the crushing roller to crush the internal straw. After the crushed straw enters the second crushing chamber through the circulation port, the crushing knife crushes the straw for a second time. It has the characteristics of strong practicality and good crushing effect.

[0004] Regarding the above-mentioned related technologies, the cooperation of the crushing roller and the crushing knife can achieve the effect of multiple crushing of straw, which is beneficial to improving the crushing effect of the equipment. However, when the crushed material is discharged through the discharge pipe, a large amount of dust may be generated, and the crushed material is inconvenient to store. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a straw crushing device and method with an automatic identification and drying forming structure, which adopts the following technical solutions:

[0010] By adopting the above technical solution, when the equipment is used, the staff places the straw on the first conveyor belt, and transports the straw to the crushing frame through the first conveyor belt. When the straw is transported, the straw is moved by the toggling component, and then the straw is automatically identified by the scanning detector, which plays the role of selecting whether there is moldy part in the straw. When the equipment detects moldy straw, the straw is transported to the bottom of the support plate through the first conveyor belt, and the moldy straw is clamped by the selecting component and transported to the outside of the first conveyor belt, which can play the role of selection, thereby helping to maintain the processing quality of the material.

[0011] The selected straw is transported to the crushing frame, and the crushing component is operated to crush the straw. The crushed straw enters the conveying barrel through the inlet and outlet opened on the top of the conveying barrel, and then the heat generated by the heating layer is introduced into the conveying barrel, which can heat and dry the material. The material is then transported through the conveying component to allow the material to enter the extrusion frame through the discharge pipe. The conveying component not only transports the material, but also stirs the material, which is beneficial to improve the uniformity of heating the material, and thus helps to improve the drying efficiency of the material. When the material enters the extrusion frame, the extrusion component can be operated to extrude the material, so that the crushed material is squeezed into blocks, which is convenient for the subsequent operation and storage of the staff, and helps to reduce the amount of dust generated during material unloading and transportation.

[0012] After the material is squeezed into blocks, it is transported away through the second conveyor belt, which helps to reduce the workload of the staff.

[0066] A straw crushing method with an automatic identification and drying forming structure comprises the following steps:

[0067] S1. Feeding and screening step: The straw is conveyed to the crushing frame 8 through the first conveyor belt 14. When the straw is conveyed by the first conveyor belt 14, the second electric clamp 26 can be driven to descend by the second telescopic rod 27, and the straw is clamped by the second electric clamp 26. Then, the screw 49 is driven to rotate by the third reduction motor 48, so that the second support block 28 is located in the support box 29 and slides. The second support block 28 moves synchronously with the second telescopic rod 27 and the second electric clamp 26, and the second electric clamp 26 is continuously loosened when it moves, so that the straw falls. , then the falling straw is automatically identified by the scanning detector 25 to detect whether there is moldy straw. When moldy straw is found, the straw is conveyed to the bottom of the support plate 12 through the first conveyor belt 14, and the first electric clamp 24 is driven downward by the first telescopic rod 23 to clamp the moldy straw by the first electric clamp 24. Then, the first support block 22 is driven by the third cylinder 31 to drive the first electric clamp 24 to move the moldy straw out of the first conveyor belt 14, thereby playing the role of selecting straw, which is conducive to maintaining the processing quality of subsequent materials;

[0068] S2, crushing step: the selected straw enters the crushing frame 8, and the first reduction motor 34 drives the connected second rotating rod 45 to rotate. The two second rotating rods 45 are engaged and rotated synchronously through the second driving gear 39, so that the second rotating rods 45 drive the same group of crushing rollers 44 to rotate, which can play the role of crushing the straw, and one of the second driving gears 39 drives the transmission gear 38 to rotate, and the transmission gear 38 drives the adjacent first driving gear 36 to rotate. Through the cooperation of the two first driving gears 36, the two first rotating rods 35 drive the same group of crushing rollers 44 to rotate synchronously, thereby achieving the effect of further crushing the straw, which is beneficial to improving the crushing quality of the equipment;

[0069] S3, drying and extrusion molding step: the crushed material enters the conveying cylinder 6 through the inlet and outlet opened at the top of the conveying cylinder 6, and then the heat generated by the heating layer is conducted into the conveying cylinder 6, which can play the role of drying the material, and at the same time, the second reduction motor 42 drives the support rod 46 to rotate, and the support rod 46 drives the spiral blade 43 to rotate, thereby playing the role of conveying and stirring the material, which is beneficial to improving the uniformity of heating the material, and thus is beneficial to improving the drying efficiency of the material. The dried material enters the extrusion frame 2 through the discharge pipe 16 under the drive of the spiral blade 43, and then drives the first extrusion molding 40 to enter the extrusion frame 2 through the second cylinder 18, and then drives the second extrusion molding 41 to move toward the first extrusion molding 40 through the first cylinder 3. Through the cooperation of the first extrusion molding 40 and the second extrusion molding 41, the material can be extruded into blocks, which is convenient for subsequent transportation and storage of the material.

[0070] S4, unloading step: After the material is extruded into blocks, the second extrusion forming part 41 is driven by the first cylinder 3 to move toward the end of the extrusion frame 2, and the first extrusion forming part 40 is driven by the second cylinder 18 to separate from the extrusion frame 2. The cooperation between the first extrusion forming part 40 and the second extrusion forming part 41 can play the role of clamping the shaped material. After the block material moves out of the extrusion frame 2, the first extrusion forming part 40 and the second extrusion forming part 41 are separated from each other, so that the block material falls onto the second conveyor belt 19. The block material is transported away from the block by the second conveyor belt 19, which is convenient for the staff to carry and place it later, thereby reducing the generation of dust during material unloading and transportation;

[0071] S5, dust collection step. When the straw enters the crushing frame 8, dust may be generated. The exhaust fan 21 generates suction to make the dust enter the dust collection frame 10, and then the dust enters the collection frame 4 through the multi-way connector 11 and the conduit 7. The collection frame 4 is provided with a dust filter cloth 33 and filter cotton 32, which play the role of filtering dust in the gas, so that the dust remains in the collection frame 4, which can collect the dust and help prevent the dust from entering the collection frame 4, which is convenient for the subsequent continuous use of the exhaust fan 21. The side wall of the collection frame 4 is hinged by the sealing plate, which is convenient for the staff to open the sealing plate to collect dust, and the dust filter cloth 33 and filter cotton 32 are fixed by the limiting block to the limiting groove opened on the inner wall of the collection frame 4, which is convenient for the staff to clean and replace the dust filter cloth 33 and filter cotton 32 later, which is beneficial to maintain the filtering effect of the equipment.

[0072] The implementation principle of the embodiment of the present invention is: when the equipment is used, the staff places the straw on the first conveyor belt 14, and conveys the straw to the crushing frame 8 through the first conveyor belt 14. When the straw is conveyed, the straw is moved by the toggling component, and then the straw is automatically identified by the scanning detector 25, which plays the role of selecting whether there is moldy part in the straw. When the equipment detects moldy straw, the straw is conveyed to the bottom of the support plate 12 through the first conveyor belt 14, and the moldy straw is clamped by the selecting component and conveyed to the outside of the first conveyor belt 14, which can play the role of selection, thereby facilitating the maintenance of the processing quality of the material.

[0073] The selected straw is transported to the crushing frame 8, and the crushing component is operated to crush the straw. The crushed straw enters the conveying cylinder 6 through the inlet and outlet opened at the top of the conveying cylinder 6, and then the heat generated by the heating layer is introduced into the conveying cylinder 6, which can heat and dry the material. The material is then transported by the conveying component to allow the material to enter the extrusion frame 2 through the discharge pipe 16. The conveying component not only transports the material, but also stirs the material, which is beneficial to improve the uniformity of heating the material, and thus is beneficial to improving the drying efficiency of the material. When the material enters the extrusion frame 2, the extrusion component can be operated to extrude the material, so that the crushed material is squeezed into blocks, which is convenient for the subsequent operation and storage of the staff, and is beneficial to reduce the amount of dust generated during material unloading and transportation.

[0074] After the material is squeezed into blocks, it is transported away through the second conveyor belt 19, which helps to reduce the workload of the staff. When the straw enters the crushing frame 8, dust may be generated. The exhaust fan 21 can generate wind to make the dust enter the collection frame 4, which can collect the dust, which helps to reduce the generation of dust and thus improve the environmental friendliness of the equipment.

[0075] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
