Description

Technical Field

[0001] This invention relates to the field of grain grinding equipment, specifically to a processing device for returning agricultural waste to the field. Background Technology

[0002] After being crushed and ground, the waste from crops can be used as fertilizer back to the fields, thereby significantly improving the efficiency of subsequent processing of crop waste and avoiding the pollution to the atmosphere caused by the traditional burning of crop waste. After being crushed and ground into granules, crop waste can be efficiently integrated into the soil, thus playing a role in soil insulation and other functions. Therefore, in order to facilitate the processing of crop waste, we propose a crop waste return-to-field processing equipment.

[0003] The existing technology still has the following drawbacks in its use: 1. The grinding effect of existing agricultural waste return processing equipment is not ideal. When grinding agricultural waste, the traditional grinding method is not ideal because agricultural waste contains branches, leaves, stalks and stems, and different parts have different hardness and moisture content, which makes grinding difficult. During the grinding process, a large number of branches, leaves, stalks and stem fragments are mixed, which can easily lead to poor local grinding effect. This results in inconsistent particle size in the processed particles, and a secondary screening of the processed particles is required later. This increases the processing steps of agricultural waste return to the field and reduces the efficiency and practicality of agricultural waste return processing equipment. 2. Existing agricultural waste return processing equipment has relatively limited functionality. When crushing and grinding agricultural waste, it is necessary to add appropriate additives to the returned agricultural waste according to the type of waste and the fertility of the farmland. However, traditional agricultural waste return processing equipment does not have this function, which means that agricultural waste can only be crushed and ground, thus narrowing the scope of application of agricultural waste return processing equipment.

[0004] In view of this, we propose a crop waste return-to-field processing equipment to solve the existing problems. Summary of the Invention

A transmission belt is mounted around the outer side of one end of the front of the crushing roller, and the other side of the transmission belt is mounted around the outer side of the drive roller. The diameter of the crushing roller is smaller than the diameter of the drive roller. The grinding assembly is installed inside the housing below the crushing roller; The inner side of the housing is located between the drive roller and the crushing roller, and a partition plate is fixedly installed near the bottom of the housing. A separation plate is fixedly installed on the left side of the partition plate.

[0007] Preferably, the grinding assembly includes a filter cylinder with several filter holes at the bottom and an open top. A rotating roller is rotatably mounted inside the filter cylinder, and several central shafts are fixedly mounted on the outer side of the rotating roller. A grinding roller is fixedly mounted on the outer side of the central shafts. The grinding roller is an elliptical cross-section rod-shaped object, and one side of the grinding roller contacts the inner wall of the filter cylinder. Several guide grooves are provided on the outer surface of the grinding roller, and several guide frames are fixedly mounted on both sides of the grinding roller.

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-8 As shown, the present invention proposes a crop waste return-to-field processing device, comprising a housing 1, an inner shell 2, a crushing roller 3, and a grinding assembly 5. A first motor 101 is fixedly installed on the left side of the front of the housing 1, and a second motor 110 is fixedly installed on the right side of the front of the housing 1. A drive roller 102 is mounted on the upper left side of the interior of the housing 1 via a bearing, and the drive roller 102 is fixedly connected to the output shaft of the first motor 101. A driven roller 103 is mounted on the bottom of the drive roller 102 inside the housing 1 via a bearing. A foam pad 104 is fixedly installed on the lower left side of the interior of the housing 1. The housing 1 provides mounting positions for surrounding components. The first motor 101 is a YE3-100KW type. When the motor 101 is powered on, it can rotate, which in turn drives the drive roller 102 to rotate. The second motor 110 is a YE3-100KW type. When the second motor 110 is powered on, it can drive the rotating roller 502 to rotate, which causes the central shaft 505 and its outer components to move in a circular motion around the rotating roller 502. The drive roller 102 can rotate, which then cooperates with the driven roller 103 to convey the agricultural waste to be processed into the inside of the device. Then, it cooperates with the crushing roller 3 to crush the agricultural waste during the conveying process. The foam pad 104 can provide elastic protection for the bottom of the driven roller 103, thereby preventing hard objects from colliding with the shell 1 during high-speed conveying, and thus preventing damage to the shell 1. An inner shell 2 is fixedly installed inside the outer shell 1. A mounting box 204 is located on the right side of the inner shell 2. A temperature sensor 201 is fixedly installed on the top side of the inner shell 2, and a humidity sensor 202 is fixedly installed on one side of the temperature sensor 201. Two sets of comb teeth 203 are fixedly installed on the inner wall of the inner shell 2. A liquid storage tank 205 is fixedly installed at the bottom of the inner shell 2. A feed pump is fixedly installed on the top side of the liquid storage tank 205, and a water guide pipe 206 extending to the inner side of the inner shell 2 is installed at the output end of the feed pump. The inner shell 2 provides mounting positions for surrounding components, and the mounting box 204 provides mounting positions for internal components. The temperature sensor 201 is a COS-03 type and can detect the ambient temperature inside the device, thus facilitating the device's control over the internal ambient temperature. The humidity is controlled by a humidity sensor 202, which is an OHR-WS10G type. The humidity sensor 202 can detect the ambient humidity inside the device, so that the humidity inside the device can be adjusted during operation. The comb teeth 203 can remove impurities attached to the surface of the crushing roller 3, so as to prevent impurities from getting tangled on the surface of the crushing roller 3 and causing the crushing roller 3 to be obstructed from rotating. The liquid storage tank 205 can store a certain amount of fluid according to the usage requirements, and then add the additives that need to be added into the filter cartridge 501. During the crushing and grinding process, the agricultural waste and the additives are fully mixed, thereby improving the processing effect of the device on agricultural waste. The feed pump is a CSP-XW type. The feed pump can draw the fluid inside the liquid storage tank 205 and then pump the drawn fluid into the filter cartridge 501. Inside the housing 1, near the center, a crushing roller 3 is rotatably mounted. Several cutting teeth 301 are welded at equal intervals on the outer side of the crushing roller 3. A transmission belt 302 is mounted around the outer side of one end of the front of the crushing roller 3, and the other side of the transmission belt 302 is mounted around the outer side of the drive roller 102. The diameter of the crushing roller 3 is smaller than the diameter of the drive roller 102. The crushing roller 3 can rotate at high speed, thereby crushing agricultural waste into smaller fragments, which is convenient for subsequent grinding of agricultural waste. The cutting teeth 301 can improve the crushing effect of the crushing roller 3 on agricultural waste. The transmission belt 302 can connect the crushing roller 3 and the drive roller 102, so that when the drive roller 102 rotates, it can drive the crushing roller 3 to rotate synchronously. Inside the housing 1, below the crushing roller 3, there is a grinding component 5. The grinding component 5 can grind the crushed agricultural waste, so that the agricultural waste is ground into fine particles, which makes it convenient to return the agricultural waste to the field for sowing later. The inner side of the housing 1 is located between the drive roller 102 and the crushing roller 3, and a partition plate 4 is fixedly installed near the bottom of the housing 1. A separation plate 402 is fixedly installed on the left side of the partition plate 4. The partition plate 4 can separate the materials on both sides, so that different materials are guided to fall into the recycling box 108 and the waste collection trough 106 respectively. The separation plate 402 can screen the solid waste mixed in the agricultural waste, thereby removing impurities such as stones mixed in the agricultural waste and avoiding damage to other components.

[0018] Furthermore, the grinding assembly 5 includes a filter cylinder 501. The bottom of the filter cylinder 501 has several filter holes, and the top of the filter cylinder 501 is an open structure. A rotating roller 502 is rotatably mounted inside the filter cylinder 501. Several central shafts 505 are fixedly mounted on the outer side of the rotating roller 502. A grinding roller 506 is fixedly mounted on the outer side of the central shafts 505. The grinding roller 506 is an elliptical cross-section rod-shaped object, and one side of the grinding roller 506 contacts the inner wall of the filter cylinder 501. Several guide grooves are provided on the outer surface of the grinding roller 506, and several guide frames 507 are fixedly mounted on both sides of the grinding roller 506. The guide frames 507 have a triangular hollow structure, and the end points of the guide frames 507 are spherical structures. A fixing plate 503 is fixedly mounted on the right side of the filter cylinder 501. Several guide grooves are opened inside the fixing plate 503. An exhaust hole 504 is opened at the connection point between the filter cylinder 501 and the guide grooves, and the exhaust hole 504 opens vertically downwards. The filter cylinder 501 can temporarily store the crushed agricultural waste, so that it can be ground by the grinding roller 506. The rotating roller 502 is driven by the second motor 110 to rotate, thereby driving the grinding roller 506 to move in a circle. After the central shaft 505 and the grinding roller 506 move in a circle around the rotating roller 502, they can cooperate with the filter cylinder 501 to grind the crushed agricultural waste, so that the agricultural waste is ground into relatively fine particles inside the filter cylinder 501, which is convenient for the agricultural waste to be returned to the field for sowing later. The guide frame 507 can move synchronously with the movement of the grinding roller 506, thereby separating the mixed waste inside the filter cylinder 501. The smaller agricultural waste particles fall first, while the unground or larger waste particles are pushed to both sides, which makes it easier to grind the larger waste particles multiple times, ensuring the grinding effect of the device on agricultural waste.

[0019] Furthermore, a support frame 105 is fixedly installed at the bottom of the shell 1. A waste collection trough 106 is slidably installed on the top left side of the support frame 105, and a recycling box 108 is slidably installed on the top right side of the support frame 105. A first guide trough 107 is fixedly installed on the bottom left side of the shell 1, and a second guide trough 109 is fixedly installed on the bottom right side of the shell 1. The support frame 105 can support the shell 1 to ensure the installation stability of the device. The waste collection trough 106 can collect the impurities screened out by the separation plate 402 for centralized processing in the later stage. The recycling box 108 can collect the processed crops so that the processed crops can be stored in the recycling box 108 for centralized processing. The first guide trough 107 can guide the impurities to the waste collection trough 106, and the second guide trough 109 can guide the processed crop particles to the recycling box 108 for storage.

[0020] Furthermore, a blower and a current controller are fixedly installed inside the mounting box 204. Several air guide pipes are fixedly installed on one side of the blower, and the air guide pipes extend to the inside of the inner shell 2. An arc-shaped heater is fixedly installed on one side of the current controller, and one end of the arc-shaped heater extends to the inside of the inner shell 2. The blower is an RB9733 type. The blower can spray airflow onto the crushing roller 3 through the air guide pipes, thereby assisting the comb 203 in removing impurities and dust from the surface of the crushing roller 3. It can also regulate the temperature and humidity inside the device by driving the airflow inside the device. The current controller can be connected to an external power source to power the arc-shaped heater, so that it generates heat after being powered on, so as to heat the air around the crushing roller 3. This can heat the crushing roller 3 when the humidity of the crop is high, thereby improving the crushing effect of the crushing roller 3 on crop waste.

[0021] Furthermore, the front side of the roller 502 extends to the front side of the housing 1, and the roller 502 is fixedly connected to the output shaft of the second motor 110.

[0022] Furthermore, the separation plate 402 has several sieve holes inside, and several guide plates 401 are fixedly installed on the top right side of the separation plate 402. The separation plate 402 is installed horizontally, and the rightmost edge of the separation plate 402 is provided with an upwardly sloping arc surface.

[0023] Working principle: After the device is assembled and inspected to ensure it is correct, the first motor 101 is energized and rotates, driving the drive roller 102 to rotate. The drive roller 102 drives the crushing roller 3 to rotate synchronously via the transmission belt 302. The second motor 110 is energized and rotates, driving the rotating roller 502 to rotate. This causes the central shaft 505, grinding roller 506, and guide frame 507 to move in a circular motion around the rotating roller 502. The agricultural waste to be processed is sequentially placed between the drive roller 102 and the driven roller 103 through the opening on the left side of the housing 1. The agricultural waste is then processed by the drive roller 102 and the driven roller 103. The device grips and conveys the agricultural waste at a uniform speed into the device. The agricultural waste is guided by the separation plate 402 and the guide plate 401 and moves towards the crushing roller 3. After the agricultural waste comes into contact with the crushing roller 3, it is cut into several fragments by the cutting teeth 301 and falls into the filter cylinder 501. The fragments of agricultural waste are ground by the filter cylinder 501, the grinding roller 506 and the guide frame 507, so that the processed agricultural waste falls into the recycling box 108. The solid impurities separated from the separation plate 402 fall into the waste collection box for collection.
