Description

Technical Field

[0001] This utility model relates to the technical field of straw processing devices, and in particular to a corn straw processing device. Background Technology

[0002] With the development of agricultural modernization, corn, as one of the main food crops, has seen its planting area continuously expand. At the same time, the yield of corn stalks has also increased. How to efficiently and environmentally dispose of corn stalks has become an important issue that urgently needs to be addressed in the agricultural sector.

[0003] Currently, existing straw processing equipment has shortcomings in crushing, compressing, and molding, resulting in low-quality straw that fails to meet actual needs.

[0004] Firstly, in terms of straw crushing, some traditional crushing equipment has poor crushing effect and cannot crush the straw into smaller pieces, which affects subsequent processing steps. Some equipment is prone to straw blockage during the crushing process, which reduces production efficiency and increases equipment maintenance costs.

[0005] Secondly, the process of crushing, compressing and cutting straw into blocks is generally divided into multiple steps, which cannot be completed in one go, thus reducing work efficiency. Utility Model Content

[0006] This utility model relates to a corn stalk processing device, which solves the problems of poor crushing effect of crushing equipment, which cannot fully crush the stalks into smaller pieces, thus affecting subsequent processing steps. Some equipment is prone to stalk blockage during the crushing process, which reduces production efficiency and increases equipment maintenance costs. In addition, the process of crushing, compressing and cutting stalks is generally divided into multiple process steps, which cannot be formed in one step, thus reducing work efficiency.

[0007] This utility model provides a corn stalk processing device, specifically including: a crushing box;

[0008] A feed pipe is fixedly installed on the upper end face of the crushing box. The feed pipe has a funnel-shaped structure. Two inclined support legs are installed on the left and right ends of the lower end face of the crushing box. A connecting pipe is fixedly installed in the middle of the lower end face of the crushing box.

[0009] Two first motors are symmetrically installed on the front surface of the crushing box. The front end of the first motor is connected to a first drive shaft. The end of the first drive shaft is rotatably connected to the rear surface of the crushing box. Crushing teeth are evenly installed on the surface of the first drive shaft.

[0010] The push cylinder is located below the crushing box and is fixedly connected to the connecting pipe. The push cylinder is connected to the crushing box through the connecting pipe.

[0011] An extruder is fixedly installed at the end of a feed cylinder, and a placement plate is fixedly installed on the upper surface of the extruder. A third motor is installed on the surface of the placement plate.

[0012] The second motor is fixedly installed on the rear end face of the propulsion cylinder, and the front end of the second motor is connected to the second drive shaft.

[0013] Furthermore, the inner end faces of the left and right side walls of the crushing box are evenly equipped with baffles, the outer end faces of the baffles are inclined, and the crushing teeth are located between two adjacent baffles.

[0014] Furthermore, a propulsion blade is mounted on the outer end face of the second drive shaft. The propulsion blade has a spiral structure, and the outer end face of the propulsion blade is in contact with the inner wall of the propulsion cylinder.

[0015] Furthermore, the outlet end of the propulsion cylinder has a funnel-shaped structure, and four discharge pipes are installed inside the extruder.

[0016] Furthermore, the front end of the third motor is connected to a third drive shaft, and a cutter is fixedly installed at the end of the third drive shaft. There are three cutters, and the three cutters are arranged in a ring structure.

[0017] This utility model provides a corn stalk processing device, which has the following beneficial effects:

[0018] In this utility model:

[0019] 1. The crushing teeth evenly installed on the surface of the first drive shaft and the baffles reasonably distributed on the inner end face of the side wall of the crushing box work together to ensure that the corn stalks entering the crushing box are crushed relatively evenly, avoiding the situation that some stalks are not crushed completely or that the size difference is too large, which is conducive to the consistency of subsequent processing and the stability of product quality.

[0020] 2. Inside the feed cylinder, a second drive shaft equipped with spiral propulsion blades is rotated by a second motor, and the outer end face of the propulsion blades is in contact with the inner wall of the feed cylinder. This structural design allows the crushed straw fragments to be steadily and orderly pushed toward the extruder, just like in a screw conveyor, effectively preventing material from getting stuck or piling up during the pushing process and ensuring the continuity of the entire processing flow.

[0021] 3. The outlet end of the feed cylinder adopts a funnel-shaped structure. This design helps to concentrate and gather the material, further facilitating the smooth entry of the material into the extruder, reducing material loss and residue during the transmission process, improving material utilization and the reliability of the equipment operation.

[0022] 4. The third motor installed on the upper end of the extruder drives the cutter to rotate. The three cutters arranged in a ring structure can accurately cut the material extruded from the discharge pipe, ensuring that the final corn stalk processing product meets the requirements. The size of the cut pieces is relatively uniform, which meets the specifications and standards of subsequent processing or use, and improves the overall quality of the product.

The front end of the first motor 2 is connected to the first drive shaft 201. The end of the first drive shaft 201 is rotatably connected to the rear end surface of the crushing box 1. Crushing teeth 2011 are evenly installed on the surface of the first drive shaft 201.

[0039] The push cylinder 3 is located below the crushing box 1. The push cylinder 3 is fixedly connected to the connecting pipe 104 and is connected to the crushing box 1 through the connecting pipe 104.

[0040] Extruder 4 is fixedly installed at the end of the feed cylinder 3. A placement plate 402 is fixedly installed on the upper end face of the extruder 4. A third motor 6 is installed on the surface of the placement plate 402.

[0041] The second motor 5 is fixedly installed on the rear end face of the propulsion cylinder 3, and the front end of the second motor 5 is connected to the second drive shaft 501.

[0042] Among them, the inner end faces of the left and right side walls of the crushing box 1 are evenly installed with baffles 103. The outer end face of the baffles 103 is inclined. The crushing teeth 2011 are located between two adjacent baffles 103. The baffles 103 evenly installed on the inner end faces of the left and right side walls of the crushing box 1 are inclined, which can ensure that the straw can be concentrated between the two crushing teeth 2011, so that the straw is crushed into smaller fragments.

[0043] Among them, the outer end face of the second drive shaft 501 is equipped with a propulsion blade 5011. The propulsion blade 5011 has a spiral structure. The outer end face of the propulsion blade 5011 is in contact with the inner wall of the propulsion cylinder 3. The outlet end of the propulsion cylinder 3 has a funnel-shaped structure. The extruder 4 has four discharge pipes 401 installed inside. The crushed corn stalks can be compressed in the propulsion cylinder 3 and then discharged in strips from the discharge pipes 401.

[0044] The third motor 6 is connected to the front end of the third drive shaft 601. The end of the third drive shaft 601 is fixedly installed with a cutter 6011. There are three cutters 6011, which are arranged in a ring structure. In use, the third motor 6 drives the third drive shaft 601 to rotate, and the three cutters 6011 fixedly installed at the end of the third drive shaft 601 rotate accordingly. The cutters 6011 cut the corn stalks and finally obtain the corn stalks processed product that meets the requirements.

[0045] Example 2, based on Example 1, such as Figures 1-6 As shown, a storage bucket can be placed below the discharge pipe 401. The cut particles are temporarily stored in the storage bucket for easy transfer by workers later.

[0046] The working principle of this embodiment:

[0047] In this invention, corn stalks enter the crushing chamber 1 through a funnel-shaped feed pipe 101. The funnel-shaped design of the feed pipe 101 facilitates the smooth entry of the stalks into the device and serves as a guide for feeding. Support legs 102 are installed at the left and right ends of the lower end face of the crushing chamber 1 at an angle, providing stable support for the device and ensuring the smooth operation of the entire process. After the corn stalks enter the crushing chamber 1, two first motors 2 symmetrically installed on the front surface of the crushing chamber 1 begin to operate. The first motors 2 drive the first drive shaft 201 to rotate. Since the end of the first drive shaft 201 is rotatably connected to the rear end surface of the crushing chamber 1, it can rotate stably. The crushing teeth 2011 evenly installed on the surface of the first drive shaft 201 rotate with the shaft, crushing the corn stalks. Simultaneously, the baffles 103 evenly installed on the inner end faces of the left and right side walls of the crushing chamber 1 have an inclined structure, ensuring that the stalks can be concentrated between the two crushing teeth 2011, causing the stalks to be crushed into smaller fragments. The crushed corn stalk fragments are then processed through… The straw fragments fall into the feed cylinder 3 through the connecting pipe 104 in the middle of the lower end face of the crushing box 1. At this time, the second motor 5 installed on the rear end face of the feed cylinder 3 starts, driving the second drive shaft 501 to rotate. The feed blades 5011 installed on the outer end face of the second drive shaft 501 have a spiral structure, and the outer end face of the feed blades 5011 is in contact with the inner wall of the feed cylinder 3. The feed blades 5011 are like a screw conveyor, pushing the crushed straw fragments along the feed cylinder 3 towards the extruder 4. The outlet end of the feed cylinder 3 has a funnel-shaped structure. This structure helps to concentrate the material and smoothly transport it to the extruder 4. The straw fragments pushed to the extruder 4 are extruded through the four discharge pipes 401 installed inside the extruder 4. At the same time, the third motor 6 installed on the placement plate 402 on the upper end face of the extruder 4 starts to work. The third motor 6 drives the third drive shaft 601 to rotate. The three cutters 6011 fixedly installed at the end of the third drive shaft 601 rotate accordingly and cut the straw fragments, finally obtaining the corn straw processing product that meets the requirements.
