Description

Technical Field

[0001] The present invention relates to a straw treatment and utilization device, specifically to an agricultural straw treatment and reuse device, belonging to the technical field of straw treatment. Background Art

[0002] Straw is the general term for the stems, leaves (ears) of mature crops. It usually refers to the remaining parts after harvesting the seeds of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains). More than half of the products of crop photosynthesis are present in the straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc., and is a renewable biological resource with multiple uses. During the process of recycling straw, it is necessary to first crush the straw, and then further process the crushed straw according to the usage requirements, so as to achieve the effect of straw treatment and reuse.

[0003] In the prior art, a crusher is usually used to crush straw. Since the recycled straw is usually placed outdoors in the external environment, dust and other sundries adhere to the surface of the straw. If it is directly put into the crusher for crushing, the sundries inside the straw will damage the internal parts of the crusher, and the dust inside the straw will cause the crushed straw blocks to contain more dust, affecting the quality of subsequent deep processing of straw. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose an agricultural straw treatment and reuse device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] Optionally, a first motor is installed on one of the moving blocks. The output end of the first motor is installed with a rolling roller. One end of the rolling roller away from the first motor is rotatably connected to the other moving block through a second rotating shaft. A groove is formed inside the rolling roller, and two fourth electric telescopic rods are installed inside the groove. The telescopic ends of the two fourth electric telescopic rods are commonly connected to a rectangular plate, and a cutting knife is slidably installed inside the rectangular plate.

[0011] Optionally, the second processing mechanism includes a second motor installed on the top of the feeding box. The output end of the second motor extends into the feeding box and is connected to a driving shaft. A plurality of crushing knives are installed on the outer wall of one end of the driving shaft located inside the crushing box.

[0012] Optionally, the drying mechanism includes a drying box slidably installed inside the processing box. An entrance and exit for the drying box to enter and exit are formed on the outer wall of one side of the processing box close to the fixing frame. A first sliding groove is formed on the top of the fixing frame, and a first sliding block capable of moving back and forth in the first sliding groove is installed at the bottom of the drying box.

[0013] Optionally, a fifth electric telescopic rod is rotatably installed inside the driving shaft through a bearing. Two slots are formed on the outer wall of the fifth electric telescopic rod, and two telescopic insertion rods with telescopic ends adapted to the slots are installed inside the driving shaft.

[0014] Optionally, the telescopic end of the fifth electric telescopic rod is connected to a heating plate. Telescopic limiting rods are installed inside both ends of the heating plate.

[0016] The beneficial effects of the present invention are:

[0017] 1. In this invention, through the first processing mechanism provided, the straw to be processed can be placed inside the moving box. By controlling the two rotating plates to swing up and down within the opening, the stacked straw inside the moving box can be swung and flattened, and at the same time, the dust on the surface of the straw can be shaken off. And after the cutting knife finishes cutting the straw, control the rectangular plate to extend downward and abut against the bottom of the moving box. The screw rod rotates to drive the rolling roller and the rectangular plate to move back and forth inside the moving box, so as to be able to push the straw segments to move back and forth inside the moving box, and discharge the dust on the surface of the straw segments and the sundries mixed inside through the multiple filter slots opened at the bottom of the moving box, further improving the quality of removing dust and sundries inside the straw.

[0018] 2. In this invention, through the drying box provided, the crushed straw blocks can be centrally collected. And by the heating plate rotating inside the drying box, the straw blocks inside the drying box are rotated, dried and sterilized to remove the pest eggs existing inside the straw. The two horizontal pressing plates located at the top of the drying box can prevent some straw blocks from overflowing from the top of the drying box during the rotation of the heating plate inside the drying box.

[0019] 3. In this invention, after the drying and sterilization work of the straw blocks is completed, the second linear motor can be controlled to start, driving the two horizontal pressing plates to move downward slowly together to press the straw blocks inside the drying box. Then control the first linear motor to start, driving the drying box to move out from the entrance and exit inside the first chute, facilitating the taking out of the processed straw blocks. And the straw blocks pressed by the two pressing plates can prevent some straw blocks from overflowing from the top opening during the movement of the drying box, improving the cleanliness near the entrance and exit of the processing box.

[0020] 4. In this invention, when processing straw with more moisture inside, after the cutting knife cuts the straw with more moisture into straw segments of the same length, control the first motor to drive the rolling roller to rotate slowly. Then, through the rotation of the screw rod, drive the rotating rolling roller to roll the straw segments with more moisture, so that the moisture contained inside the straw segments can be discharged downward through the multiple filter slots after being rolled by the rolling roller, reducing the moisture inside the straw.

The telescopic ends of the two first electric telescopic rods 9 are in contact with the top end of the fixed frame 8. By arranging the two first electric telescopic rods 9 at the bottom of the rotating frame 5, support can be provided for the rotating frame 5 to be in a horizontal state.

[0036] As a technical optimization scheme of the present invention, a moving box 6 is slidably installed inside the rotating frame 5. Second electric telescopic rods 14 are installed on the outer walls of both sides of the rotating frame 5. The telescopic ends of the two second electric telescopic rods 14 are both connected to the moving box 6. Two openings are opened at the bottom of the moving box 6.

A plurality of filter slots are opened inside the two rotating plates 21 and at the bottom of the moving box 6. The second electric telescopic rods 14 arranged on both sides of the rotating frame 5 can drive the moving box 6 to move back and forth inside the rotating frame 5 during the telescopic movement of the telescopic ends; a first driving device for driving the two first rotating shafts 22 to rotate is pre-installed inside the bottom end of the moving box 6, so as to drive the two rotating plates 21 to rotate inside the openings.

[0037] As a technical optimization scheme of the present invention, two third electric telescopic rods 10 are installed on the outer walls of both sides of the rotating frame 5 near the two second electric telescopic rods 14. The telescopic ends of the two third electric telescopic rods 10 are jointly connected to a moving rod 11. A sliding rod 13 and a lead screw 12 are respectively installed inside the two moving rods 11. Moving blocks 16 are installed on the outer walls of the sliding rod 13 and the lead screw 12. One end of the lead screw 12 can be connected to the output end of an external driving device. After the external driving device is started, it can drive the lead screw 12 to rotate forward and backward.

[0038] As a technical optimization solution of the present invention, a first motor 15 is installed on one of the moving blocks 16. The output end of the first motor 15 is equipped with a rolling roller 7. One end of the rolling roller 7 away from the first motor 15 is rotationally connected to the other moving block 16 through a second rotating shaft. A groove 18 is formed inside the rolling roller 7, and two fourth electric telescopic rods 17 are installed in the groove 18. The telescopic ends of the two fourth electric telescopic rods 17 are jointly connected to a rectangular plate 19, and a cutting knife 20 is slidably installed inside the rectangular plate 19. When the lead screw 12 rotates forward and backward, it can drive the two moving blocks 16 and the rolling roller 7 to move back and forth above the moving box 6. The rolling roller 7 itself can be driven to rotate by starting the first motor 15.

[0039] As a technical optimization solution of the present invention, the second processing mechanism includes a second motor 4. The second motor 4 is installed on the top of the feeding box 3. The output end of the second motor 4 extends into the interior of the feeding box 3 and is connected to a driving shaft 23. A plurality of crushing knives 24 are installed on the outer wall of one end of the driving shaft 23 located inside the crushing box 2. After the second motor 4 is started, it can drive the driving shaft 23 and the plurality of crushing knives 24 on its outer wall to rotate at high speed inside the crushing box 2, facilitating the crushing treatment of straw.

[0040] As a technical optimization solution of the present invention, the drying mechanism includes a drying box 27. The drying box 27 is slidably installed inside the processing box 1. An entrance and exit for the drying box 27 to enter and exit is provided on the outer wall of one side of the processing box 1 close to the fixed frame 8. A first sliding groove 28 is formed on the top of the fixed frame 8, and a first sliding block 31 that can move back and forth in the first sliding groove 28 is installed at the bottom of the drying box 27. A first linear motor is pre-installed inside the first sliding groove 28. After the first linear motor is started, it can drive the first sliding block 31 and the drying box 27 to move back and forth in the first sliding groove 28, enabling the drying box 27 to enter and exit the processing box 1 through the entrance and exit.

[0041] As a technical optimization solution of the present invention, a fifth electric telescopic rod 25 is rotationally installed inside the driving shaft 23 through a bearing 38. Two slots 36 are formed on the outer wall of the fifth electric telescopic rod 25, and two telescopic insertion rods 37 with telescopic ends adapted to the slots 36 are installed inside the driving shaft 23. The two telescopic insertion rods 37 installed inside the driving shaft 23 can drive the fifth electric telescopic rod 25 to rotate synchronously during the rotation of the driving shaft 23 after the telescopic ends of the telescopic insertion rods 37 extend and are inserted into the slots 36 on the outer wall of the fifth electric telescopic rod 25.

[0042] As a technical optimization solution of the present invention, a heating plate 32 is connected to the telescopic end of the fifth electric telescopic rod 25. Telescopic limit rods 34 are installed inside both ends of the heating plate 32. A first jack 29 and a second jack 30 adapted to the telescopic ends of the telescopic limit rods 34 are respectively formed in one end of the processing box 1 close to the crushing box 2 and the inner walls on both sides of the drying box 27. The heating plate 32 has an electric heating alloy wire inside in the prior art. After the electric heating alloy wire is electrified, it generates heat and transfers the heat to the external housing, thereby achieving the heating effect. The telescopic end of the fifth electric telescopic rod 25 is connected to the top of the heating plate 32. The position of the heating plate 32 can be adjusted up and down inside the processing box 1 by driving the heating plate 32 with the telescopic end of the fifth electric telescopic rod 25. After the heating plate 32 moves downward into the drying box 27 and upward to the top of the processing box 1, the telescopic ends of the telescopic limit rods 34 inside both ends of the heating plate 32 can be controlled to extend and be inserted into the first jack 29 and the second jack 30 formed in the inner wall of the processing box 1 and the inner wall of the drying box 27, so as to limit and fix the heating plate 32 at different positions.

[0043] As a technical optimization solution of the present invention, two second sliding grooves 33 are formed in the outer walls on both sides of the heating plate 32. Second sliders 35 are slidably installed inside the two second sliding grooves 33. A pressing plate 26 is rotatably installed between the two second sliders 35. Second linear motors are pre-installed inside the two second sliding grooves 33. After starting, the second linear motors can drive the two second sliders 35 to move up and down inside the second sliding grooves 33 and drive the pressing plate 26 arranged between the two second sliders 35 to move up and down to adjust the position.

[0044] In the present invention, when the user uses the device, please refer to Figure 2 and Figure 3 As shown, the telescopic ends of the two first electric telescopic rods 9 extend downward to support the rotating frame 5. Then, after controlling the telescopic ends of the two second electric telescopic rods 14 to extend, the moving box 6 is pushed to slide out from inside the rotating frame 5. At this time, the staff can place the straw to be processed inside the moving box 6, and drive the two rotating plates 21 to swing up and down in the opening through the first driving device preset inside the moving box 6, so that the straw stacked inside the moving box 6 can be swung and flattened, and the dust on the surface of the straw can be shaken off synchronously, so that the straw can be neatly stacked inside the moving box 6.

[0045] Next, control the telescopic ends of the two second electric telescopic rods 14 to retract, driving the moving box 6 to move into the inside of the rotating frame 5. Control the cutting knife 20 located inside the rectangular plate 19 to extend downward, and the telescopic ends of the two fourth electric telescopic rods 17 inside the groove 18 extend downward to push the cutting knife 20 downward to cut the straw inside the moving box 6. Then, drive the lead screw 12 to rotate through an external driving device to adjust the positions of the rolling roller 7 and the cutting knife 20, so that the straw inside the moving box 6 can be cut into multiple straw segments of the same length. Then, control the cutting knife 20 to retract inside the rectangular plate 19, so that the rectangular plate 19 is located at the bottom of the rolling roller 7. The telescopic ends of the two fourth electric telescopic rods 17 continue to extend downward to push the rectangular plate 19 to abut against the bottom of the moving box 6. Place a baffle at the feeding port to block the feeding port. At this time, the lead screw 12 rotates to drive the rolling roller 7 and the rectangular plate 19 to move back and forth inside the moving box 6, so as to push the straw segments to move back and forth inside the moving box 6, and discharge the dust on the surface of the straw segments and the sundries mixed inside through the multiple filter grooves opened at the bottom of the moving box 6, achieving the effect of removing the dust and sundries inside the straw.

[0046] After removing the sundries inside the straw, the rolling roller 7 can be controlled to move away from the feeding box 3 through the rotation of the lead screw 12. At this time, the telescopic end of the fifth electric telescopic rod 25 is in the retracted state, so that the heating plate 32 is located on the top of the drying box 27, and the telescopic ends of the telescopic limit rods 34 at both ends of the heating plate 32 are inserted into the inside of the first jack 29 opened at the top of the processing box 1 to limit and fix the position of the heating plate 32, so that the driving shaft 23 cannot drive the fifth electric telescopic rod 25 and the heating plate 32 to rotate synchronously during the rotation process; remove the baffle at the feeding port and control the second motor 4 to start, driving the driving shaft 23 and the multiple crushing knives 24 to rotate synchronously inside the crushing box 2. The lead screw 12 controls the rolling roller 7 and the rectangular plate 19 to move again, and the straw segments inside the moving box 6 can be pushed down into the inside of the feeding box 3 and slide down into the inside of the crushing box 2 along the way. The multiple crushing knives 24 can crush the straw segments into smaller-diameter straw blocks.

[0047] Then the straw blocks can fall downward into the interior of the drying box 27. After enough straw blocks are collected inside the drying box 27, the telescopic ends of the telescopic limit rods 34 at both ends of the heating plate 32 can be controlled to retract. The drive shaft 23 is rotated by the second motor 4, so that the telescopic ends of the two telescopic insertion rods 37 arranged inside the drive shaft 23 can be inserted into the slots 36 opened on the outer wall of the fifth electric telescopic rod 25. Then, after the pressing plate 26 between the two second sliders 35 is rotated upward to a horizontal state, the fifth electric telescopic rod 25 extends downward at the telescopic end, driving the heating plate 32 and the two pressing plates 26 in a horizontal state at the top of the heating plate 32 to move downward together, so that the heating plate 32 is inserted into the drying box 27 filled with straw blocks. The two pressing plates 26 in a horizontal state are located at the top of the drying box 27. At this time, the drive shaft 23 can drive the fifth electric telescopic rod 25 and the heating plate 32 installed at its bottom to rotate inside the drying box 27, which is convenient for uniformly drying and sterilizing the straw blocks inside the drying box 27, removing the pest eggs existing inside the straw. The two pressing plates 26 in a horizontal state at the top of the drying box 27 can prevent some straw blocks from overflowing from the top of the drying box 27 during the rotation of the heating plate 32 inside the drying box 27.

[0048] After the drying and sterilization work of the straw blocks is completed, the second linear motor can be controlled to start, driving the two second sliders 35 and the two pressing plates 26 in a horizontal state to move downward slowly together. At this time, the two pressing plates 26 in a horizontal state can press the straw blocks inside the drying box 27 during the downward movement. Then, the first linear motor is controlled to start, driving the drying box 27 to move out of the first chute 28 from the entrance and exit, which is convenient for taking out the processed straw blocks; and the straw blocks pressed by the two pressing plates 26 can prevent some straw blocks from overflowing from the top opening during the movement of the drying box 27, improving the cleanliness near the entrance and exit of the processing box 1.

[0049] When processing straw with a relatively high water content inside, for example, directly pushing the straw with a relatively high water content inside into the pulverizing box 2 for pulverizing after cutting, the situation of the pulverizing knives 24 getting entangled and the pulverizing efficiency decreasing will occur. After the cutting knife 20 cuts the straw with a relatively high water content inside the moving box 6 into straw segments of the same length, the rectangular plate 19 and the cutting knife 20 can be controlled to reset upward and be stored inside the rolling roller 7. Then, the first motor 15 is controlled to start to drive the rolling roller 7 to rotate slowly. Then, the telescopic ends of multiple third electric telescopic rods 10 are controlled to contract downward, driving the two moving rods 11 and the rolling roller 7 to move downward together until the rolling roller 7 is in close contact with the straw inside the moving box 6. Then, by rotating the lead screw 12 to drive the rotating rolling roller 7 to roll the straw segments with a relatively high water content, the water contained inside the straw segments can be discharged downward through multiple filter grooves after being rolled by the rolling roller 7, reducing the water content inside the straw.

[0050] There is still a certain amount of water inside the rolled straw segments. At this time, the drying box 27 can be controlled to move below the rotating frame 5, and the rectangular plate 19 can be controlled to extend downward from inside the rolling roller 7. By the elongation of the telescopic ends of the two second electric telescopic rods 14, the moving box 6 is driven to slowly extend from inside the rotating frame 5. Due to the obstruction of the rectangular plate 19 in the extended state inside the moving box 6, the rolled straw segments on its top can be automatically pushed into the drying box 27 for collection during the movement of the moving box 6. Then, the drying box 27 is controlled to move to the processing box 1 to first dry the straw segments, and then take them out and place them inside the moving box 6 and put them into the pulverizing box 2 for pulverizing, thus facilitating the processing of straw with a relatively high water content inside.

[0051] If more refined pulverizing treatment of the straw is required, after the cutting knife 20 cuts the straw into segments, the heating plate 32 can be driven to move upward to the top of the drying box 27 by the retraction of the telescopic end of the fifth electric telescopic rod 25. And through the elongation of the telescopic ends of the two telescopic limit rods 34 and the insertion fit with the first jack 29, the position of the heating plate 32 is limited and fixed. Then, the two pressing plates 26 are controlled to rotate upward to a horizontal state. At this time, the two horizontal pressing plates 26 and the vertical heating plate 32 can form a partition between the bottom of the pulverizing box 2 and the top of the processing box 1. At this time, the straw segments inside the moving box 6 enter the pulverizing box 2 for pulverizing and will remain inside the pulverizing box 2, enabling the multiple pulverizing knives 24 to perform more refined pulverizing treatment on the straw during the continuous rotation, improving the pulverizing accuracy of the straw. After the pulverizing of the straw inside the pulverizing box 2 is completed, the two pressing plates 26 are controlled to rotate downward to reset, so that the pulverized straw drops downward into the drying box 27 for collection.
