A multifunctional agricultural waste treatment device

Abstract

The present invention discloses a multifunctional agricultural waste treatment device, which includes a box body, a cutting mechanism, a compression mechanism, a stirring mechanism, a material distribution mechanism, and a transmission mechanism. The structure of the present invention is simple and reasonably designed. The agricultural waste entering the box body through the feed inlet can be processed in different types by manually selecting different modes. When selecting the fuel and feed mode, the agricultural waste entering from the crop straw feed inlet is first shredded by the cutter of the cutting mechanism, and the shredded waste will fall onto the weight detection plate in the compression mechanism. After the pressure sensor detects a certain weight, the compression partition plate will move horizontally to close, and at this time, the compression block will compress the agricultural waste in the compression mechanism. After the compression treatment is completed, the discharge gate is opened, and the compressed waste will be pushed out to the conveyor belt and transported away; when selecting the fertilizer treatment mode, the agricultural waste entering together from the crop straw feed inlet and the livestock and poultry manure feed inlet will be mixed and enter the stirring mechanism. After being evenly stirred by the spiral blades on the stirring and pulverizing wheel, the gate of the fertilizer discharge port will be opened, and the evenly mixed waste will be transported away through the conveyor belt. Therefore, the entire device can achieve the purpose of reusing agricultural waste and enhance the circular development of agriculture.

Detailed implementation manners

[0026] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be construed as a limitation on the protection scope of the present invention. Embodiment 1

[0027] Please refer to Figures 1-4, the present invention provides a technical solution: a multifunctional agricultural waste treatment device, including a cutting mechanism 3, the cutting mechanism 3 includes a first driving motor 3-1, a first rotating rod 3-2, and a cutting knife 3-3; two first rotating rods 3-2 are arranged in parallel, one side of each first rotating rod 3-2 is connected to a first driving motor 3-1, and a cutting knife 3-3 is arranged on each first rotating rod 3-2, and the two cutting knives 3-3 are meshed. When in actual use, the two first driving motors 3-1 provide the power required for the rotation of the first rotating rod 3-2, and at the same time control the rotation direction of the first rotating rod 3-2, respectively driving the two first rotating rods 3-2 to rotate in opposite directions. The cutting knives 3-3 meshed on the two first rotating rods 3-2 also rotate in opposite directions accordingly. The cutting knives 3-3 rotate to cut the straw, and at the same time the two cutting knives 3-3 rotate in opposite directions, and the straw can also be torn by the frictional force, which can further improve the degree of crushing of the crop straw.

[0028] On the right side of the outer shell box body 1-1, there is a stirring mechanism 5. The stirring mechanism 5 includes a second driving motor 5-1, a second rotating rod 5-2, a discharge rotating shaft 5-3, a spiral cutting knife 5-4, and a discharge plate 5-5. Two second rotating rods 5-2 are vertically arranged above the discharge plate 5-5. One end of each of the two second rotating rods 5-2 is connected to a second driving motor 5-1. The surface of the second rotating rod 5-2 is provided with a spiral cutting knife 5-4. The discharge rotating shaft 5-3 is arranged at one end inside the discharge plate 5-5. The second driving motor 5-1 provides the power required for the rotation of the second rotating rod 5-2. The second rotating rod 5-2 drives the spiral cutting knife 5-4 on its surface to fully stir the single-type or mixed agricultural waste, so as to facilitate the subsequent production of fertilizer, and at the same time avoid that the agricultural waste entering the box body is not fully crushed and stirred. Among them, the spiral cutting knife 5-4 can make the large-volume agricultural waste receive more sufficient force during stirring, so as to achieve the purpose of fully crushing relatively hard substances such as straw and livestock manure. Among them, the output gear of the second driving motor 5-1 is selectable, so that the rotation speed of the second rotating rod 5-2 driven by it can also be divided into gears, thus avoiding the situation that the speed is constant and the agricultural waste corresponding to the speed cannot be fully stirred. When the set time is reached, the second driving motor 5-1 drives the discharge rotating shaft 5-3 to rotate, opens the discharge plate 5-5, and releases the stirred product. Subsequently, the second driving motor 5-1 drives the discharge rotating shaft 5-3 to rotate, closes the discharge plate 5-5, and is convenient for the next stirring operation of the device.

[0029] Further, in actual use, the material distribution mechanism 6, the discharge port 1-5, and the conveyor belt 1-9 cooperate with each other to classify agricultural waste according to the added raw materials and the set working mode; the material distribution mechanism 6 includes a material distribution partition 6-1, a rotating shaft 6-2, and a third driving motor 6-3. The material distribution mechanism 6 is located between the cutting mechanism 3 and the stirring mechanism 5. The rotating shaft 6-2 is located at one end of the material distribution partition 6-1 to control the rotation of the material distribution partition 6-1; the third driving motor 6-3 provides power for the rotation of the rotating shaft 6-2. If the fuel feed mode is selected for discharging, the third driving motor 6-3 will drive the rotating shaft 6-2, and the rotating shaft 6-2 will drive the material distribution partition 6-1 to move to the vertical direction. At this time, the waste crops to be processed can be placed through the crop straw feed inlet 1-2. If the fertilizer mode is selected for discharging, the third driving motor 6-3 will drive the rotating shaft 6-2, and the rotating shaft 6-2 will drive the material distribution partition 6-1 to lean against the inner surface of the left box body. A certain inclination angle is set at the contact between the material distribution partition 6-1 and the box body, so that the material distribution partition 6-1 can fit with the box body to prevent the straw from leaking into the compression mechanism 4 in the fertilizer mode. At this time, agricultural waste can be placed at both outer feed inlets. A discharge port 1-5 is provided at the bottom of one side of the outer shell box body 1-1. The discharge port 1-5 includes a fuel feed discharge port 1-6 and a fertilizer discharge port 1-7. When the fuel feed mode is selected, the processed material is transported by the conveyor belt 1-9 and discharged from the fuel feed discharge port 1-6. When the fertilizer mode is selected, the processed material is transported by the conveyor belt 1-9 and discharged from the fertilizer discharge port 1-7. Thus, two different modes of the agricultural waste treatment device are realized, and the situation that the raw materials will be polluted when processing feed fuel and fertilizer is also avoided, which is convenient for the comprehensive treatment of some subsequent raw materials. Embodiment 2

[0030] On the basis of Embodiment 1, please refer to Figures 5-7, on one side of the lower part of the outer shell box body 1-1, a compression device 4 is provided. The compression device includes a compression rod 4-1, a compression block 4-2, a compression partition plate 4-3, a weight detection plate 4-4, a compression motor 4-5 and a star wheel 4-6; the compression rod 4-1 is horizontally arranged, and the right end is connected to one side of the compression block 4-2. The surface of the compression rod 4-1 is provided with threads. Star wheels 4-6 are arranged on the upper and lower sides of the compression rod 4-1. The star wheels 4-6 are arranged meshed with the threads on the surface of the compression rod 4-1. The two star wheels 4-6 are connected to the compression motor 4-5. A compression partition plate 4-3 is arranged above the compression block 4-2, and a weight detection plate 4-4 is arranged below the compression block 4-2. When in actual use, the compression partition plate 4-3 and the weight detection plate 4-4 are first controlled by the transmission mechanism 7 to extend to the right to provide a sealed space for compression. The two compression motors 4-5 provide the power required for the rotation of the star wheels 4-6. When the star wheels 4-6 are driven by the compression motors 4-5 to rotate, they can drive the compression rod 4-1 to move horizontally to the right by relying on the threads on the surface of the compression rod 4-1 with which they are meshed. The compression rod 4-1 pushes the compression block 4-2 to move to the right; when the compression is completed, the compression motor 4-5 drives the star wheels 4-6 to rotate in the reverse direction, driving the compression rod 4-1 to move to the left. The compression block 4-2 connected to the compression rod 4-1 is also driven to move to the left. Then the transmission mechanism 7 controls the weight detection plate 4-4 to retract to the left, thus realizing the automatic operation of the compression process and improving the working efficiency of the device.

[0031] On the front side of the outer shell box body 1-1, at the fuel and feed outlet 1-6, a discharge gate 1-10 is provided. A fixed groove 1-8 that is basically as wide as the discharge gate 1-10 is arranged directly below the discharge gate 1-10. When the compression mechanism 4 performs compression operations, the discharge gate 1-10 is controlled by the transmission mechanism 7 to be vertically lowered and snapped into the fixed groove 1-8. The discharge gate 1-10 can provide a sealed space for the compression operations of the compression mechanism 4, and at the same time can prevent the discharge gate 1-10 from being damaged or unable to discharge normally due to excessive pressure during compression.

[0032] The transmission mechanism 7 is provided inside the discharge gate 1-10, the compression partition plate 4-3, and the weight detection plate 4-4. The transmission mechanism 7 includes a gear 7-1, a rack 7-2 and a transmission motor 7-3. The gear 7-1 and the rack 7-2 are meshed and distributed. The transmission motor 7-3 provides the power for the rotation of the gear 7-1. The total control mechanism 2 controls the operation of the transmission motor 7-3. By controlling the working state of the transmission motor 7-3 in different modes, the rotation direction of the gear 7-1 is further controlled, so that the rack 7-2 translates, thereby controlling the expansion and contraction of the discharge gate 1-10, the compression partition plate 4-3 and the weight detection plate 4-4.

[0033] Working principle: During actual use, first press the button 2-1 on the master control mechanism 2 to select the working mode. If the fuel and feed mode is selected, the master control mechanism 2 first controls the distribution partition 6-1 to rotate to the vertical position, then controls the transmission mechanism 7 inside the discharge gate 1-10 to extend and engage with the fixed slot 1-8, and then controls the transmission mechanism 7 inside the weight detection plate 4-4 to extend. The worker can open the rotating plate 1-4 and add agricultural waste from the crop straw feed inlet 1-2. When the raw material weight on the weight detection plate 4-4 reaches the set threshold, the master control module 2 controls the compression mechanism 4 to perform compression work. After the compression work is completed, the master control mechanism 2 controls the weight detection plate 4-4 and the discharge gate 1-10 to retract, and starts the conveyor belt 1-9. At this time, the compressed raw material falls on the conveyor belt 1-9 and is transported out from the fuel and feed discharge outlet 1-6 by the conveyor belt 1-9. The master control mechanism 2 controls the compression partition 4-3 to retract, and the weight detection plate 4-4 and the discharge gate 1-10 to extend to start the next working cycle. If the fertilizer mode is selected, the master control mechanism 2 first controls the distribution partition 6-1 to rotate to the inclined position. The worker can add agricultural waste from the crop straw feed inlet 1-2 and the livestock manure feed inlet 1-3 at the same time. Then the master control mechanism 2 controls the cutting mechanism 3 to work. When the set time is reached, the second rotating rod 5-2 stops rotating. The master control mechanism 2 first starts the conveyor belt 1-9, and then controls the discharge rotating shaft 5-3 to open the discharge plate 5-5, places the agitated and cut agricultural waste on the already started conveyor belt 1-9 and transports it out of the device. After all the work is completed, the master control mechanism 2 controls the discharge rotating shaft 5-3 to close the discharge plate 5-5 to start the next working cycle. This set of processes realizes the fully automated cutting, compression, and transportation of agricultural waste raw materials, improves the functionality of the device, and further enhances its versatility.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
