Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an integrated machine for stalk pulling, crushing, film collection and impurity removal. Background Technology

[0002] Cotton, as an important economic crop, is harvested through steps including picking, stalk pulling, crushing, collecting plastic film and other impurities. Traditional harvesting methods typically require manual labor, which is not only labor-intensive but also inefficient, making it difficult to meet the demands of modern agricultural production. With the continuous development of agricultural production technology, the application of mechanized equipment is becoming increasingly widespread.

[0003] However, most existing equipment has dispersed functions, requiring multiple machines to work together, which not only increases operational complexity and cost but also affects operational efficiency. Cotton stalk removal efficiency is low, lacking a spiral conveying structure like a conical spiral tooth, making it difficult to quickly pull and orderly transport stalks along the field ridges. Incomplete pulverization is also a problem, with unreasonable blade distribution, lack of alternating staggered design, and an imperfect transmission system resulting in uneven power distribution and poor pulverization effects. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low cotton stalk removal efficiency and incomplete crushing in the existing technology, and to propose an integrated machine for stalk removal, crushing, film collection and impurity removal.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A stalk pulling, crushing, film collecting, and impurity removal integrated machine includes a pair of trapezoidal side plates, which are fixedly mounted on a tractor.

Two pairs of symmetrically distributed fixed rollers are rotatably inserted into the bottom left side of the bent inclined plate. A conical roller is fixedly sleeved on the left end of each fixed roller. A continuously spirally distributed conical helical tooth is fixed on the outer surface of each conical roller.

[0007] A U-shaped plate is fixed between the right ends of a pair of trapezoidal side plates. A first sleeve is suspended in the front left of the U-shaped plate. The front end of the first sleeve is rotatably inserted into the corresponding trapezoidal side plate, and a number of evenly distributed first augers are fixed in the rear half of the first sleeve.

[0008] The first sleeve has a first long shaft that is rotatably inserted through it. The rear end of the first long shaft is rotatably inserted through it onto the corresponding trapezoidal side plate, and the rear half of the first long shaft is fixed with several evenly distributed second augers.

[0009] The U-shaped plate has a second sleeve suspended in the right rear. The rear end of the second sleeve is rotatably inserted into the corresponding trapezoidal side plate, and the front half of the second sleeve is fixed with several evenly distributed third cutters.

[0010] The second sleeve has a second long shaft that is rotatably inserted inside and distributed through it. The front end of the second long shaft is rotatably inserted into the corresponding trapezoidal side plate, and the front half of the second long shaft is fixed with several evenly distributed fourth cutters.

[0011] Preferably, the right end of each fixed roller shaft passes through a bent inclined plate and is fitted with a concentrically fixed gear, and adjacent pairs of fixed gears are meshed with each other.

[0012] Preferably, the right ends of the second and fourth fixed roller shafts from the front extend to the right and are fitted with concentrically fixed pulleys, and the pair of pulleys are synchronously connected by a linkage belt.

[0013] Preferably, an L-shaped connecting plate is fixedly provided at the bottom of the right side of the bending inclined plate. A first through hole is provided on the L-shaped connecting plate. A first motor is fixedly installed inside the first through hole. The end of the motor shaft of the first motor is fixedly connected to the right end of the first fixed roller shaft counting from front to back.

[0014] Preferably, a through-distributed discharge channel steel is fixed to the bottom of the right side wall of the U-shaped plate, and a number of uniformly distributed impurity removal screen holes are opened on the bottom wall of the U-shaped plate.

[0015] Preferably, the first and third conical spiral teeth from front to back are arranged in a counterclockwise spiral pattern, and the second and fourth conical spiral teeth from front to back are arranged in a clockwise spiral pattern.

[0016] Several first cutters and several fourth cutters are distributed in an alternating staggered manner, as are several second cutters and several third cutters.

[0017] Preferably, the front end of the first sleeve is fitted with a first gear that is concentrically fixed, and the front end of the second long shaft is fitted with a fourth gear that is concentrically fixed, and the first gear and the fourth gear are meshed together.

[0018] Preferably, a second gear is concentrically fixed to the rear end of the first long shaft, and a third gear is concentrically fixed to the rear end of the second sleeve, with the second gear and the third gear meshing together.

[0019] Preferably, a fixed connecting plate is fixedly provided in the center of the front of the trapezoidal side plate located at the front. A second through hole is provided at the front end of the fixed connecting plate. A second motor with the output end facing upward is fixedly installed inside the second through hole. A fixed bevel gear is concentrically fixedly connected to the end of the motor shaft of the second motor.

[0020] Preferably, the front end of the first sleeve extends forward and is fitted with a first bevel gear that is concentrically fixed, and the front end of the first long shaft extends forward and is fitted with a second bevel gear that is concentrically fixed.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the trapezoidal side plate serves as the frame foundation fixed to the tractor, ensuring equipment stability. The bent inclined plate, in conjunction with the fixed roller shaft and conical roller, has continuously spirally distributed conical spiral teeth on its outer surface. Utilizing the spiral conveying principle, the cotton stalks are quickly pulled out along the cotton stalk ridges and orderly conveyed to the U-shaped plate while the tractor is moving. Multiple sets of augers are installed in the first sleeve, first long shaft, second sleeve, and second long shaft inside the U-shaped plate, and the augers are alternately and staggered to achieve efficient pulverization of the cotton stalks from all directions without dead angles, laying the foundation for subsequent processing.

[0023] 2. In this invention, the power of the second motor is converted and distributed by the meshing of the first gear and the fourth gear, the meshing of the second gear and the third gear, and the meshing transmission of the fixed bevel gear with the first bevel gear and the second bevel gear. This causes the first sleeve, the first long shaft, the second sleeve, the second long shaft and the cutter on them to rotate in a predetermined direction, ensuring that multiple sets of cutters rotate in opposite directions at high speed and work together, further improving the crushing efficiency of cotton stalks entering the U-shaped plate, and ensuring stable and efficient power transmission.

[0024] In summary, this invention features a reasonable structural design, with all components tightly fitted together. The stalk-pulling mechanism utilizes a spiral principle for efficient stalk extraction, while the crushing mechanism achieves efficient crushing through staggered distribution of the augers and different rotation directions. The impurity-removing screen allows the soil carried by the cotton stalks during crushing to fall into the farmland, and the discharge channel steel orderly discharges the crushed cotton stalks. The optimized design of the transmission system ensures effective power transmission and distribution. The overall equipment is stable and reliable, capable of efficiently completing stalk extraction, crushing, and impurity removal operations, meeting the needs of farmland operations.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1: This example provides an integrated machine for stalk pulling, crushing, film collection, and impurity removal. See [link to example]. Figures 1-8Specifically, it includes a pair of trapezoidal side plates 100. These trapezoidal side plates 100 serve as the frame foundation of the entire machine, fixedly mounted on the tractor to provide installation support for other components, ensuring the stability and reliability of the overall equipment structure. A bent inclined plate 101 is fixed between the left ends of the pair of trapezoidal side plates 100. The bent inclined plate 101 provides an installation position for components such as the fixed roller shaft 102, and guides the pulled cotton stalks smoothly into the U-shaped plate 200, achieving orderly transmission of the cotton stalks. Two pairs of symmetrically distributed fixed roller shafts 102 are rotatably inserted at the bottom left side of 101. The fixed roller shafts 102 are used to support and install the conical rollers 103. Under power drive, the conical rollers 103 are rotated to remove the cotton stalks. The left end of each fixed roller shaft 102 is fixedly fitted with a conical roller 103. The outer surface of each conical roller 103 is fixed with continuously spirally distributed conical spiral teeth 104. During the tractor's movement, the cotton stalks are quickly removed along the cotton stalk ridges using the spiral conveying principle and transported to the bending inclined plate 101.

[0037] A U-shaped plate 200 is fixed between the right ends of a pair of trapezoidal side plates 100. The U-shaped plate 200 is used to accommodate the cotton stalks that are pulled up and conveyed, providing space for the crushing of the cotton stalks. At the same time, the impurity removal screen holes 202 on its bottom wall can allow the soil carried by the cotton stalks to fall into the farmland during crushing. A first sleeve 203 is provided in the left front of the U-shaped plate 200 and is suspended. The front end of the first sleeve 203 is rotatably inserted into the corresponding trapezoidal side plate 100, and a number of evenly distributed first augers 204 are fixed in the rear half of the first sleeve 203.

[0038] The first sleeve 203 has a first long shaft 205 that is rotatably inserted inside. The rear end of the first long shaft 205 is rotatably inserted into the corresponding trapezoidal side plate 100, and a number of evenly distributed second augers 206 are fixed in the rear half of the first long shaft 205.

[0039] A second sleeve 207 is suspended in the right rear of the U-shaped plate 200. The rear end of the second sleeve 207 is rotatably inserted into the corresponding trapezoidal side plate 100, and a number of evenly distributed third cutters 208 are fixed in the front half of the second sleeve 207.

[0040] The second sleeve 207 has a second long shaft 209 that is rotatably inserted inside. The front end of the second long shaft 209 is rotatably inserted into the corresponding trapezoidal side plate 100. The front half of the second long shaft 209 is fixed with several evenly distributed fourth augers 210. The first sleeve 203, the first long shaft 205, the second sleeve 207, and the second long shaft 209 are rotatably installed in the U-shaped plate 200 as mounting carriers for the augers. Under the transmission of gears and bevel gears, the augers on them are driven to rotate, thereby realizing the crushing treatment of cotton stalks.

[0041] In the specific implementation process, such as Figure 5 and Figure 6 As shown, each fixed roller shaft 102 has a right end that passes through a bent inclined plate 101 and is fitted with a concentric fixed gear 105. The adjacent pair of fixed gears 105 are meshed with each other, so that when one fixed roller shaft 102 rotates, it can drive the other fixed roller shafts 102 to rotate synchronously, ensuring the effective transmission and coordinated operation of the stalk pulling power.

[0042] The right ends of the second and fourth fixed roller shafts 102 from the front extend to the right and are fitted with concentrically fixed pulleys. A pair of pulleys are synchronously connected by a linkage belt 106. The synchronous connection by the linkage belt 106 further enhances the transmission stability and power transmission efficiency between the fixed roller shafts 102, ensuring that multiple fixed roller shafts 102 can rotate stably and efficiently.

[0043] An L-shaped connecting plate 107 is fixedly installed on the bottom right side of the bending inclined plate 101. A first through hole is opened on the L-shaped connecting plate 107. A first motor 108 is fixedly installed inside the first through hole. The end of the motor shaft of the first motor 108 is fixedly connected to the right end of the first fixed roller shaft 102 from front to back. The first motor 108 drives the fixed roller shaft 102 by its own rotation, providing initial power for the stalk pulling operation of the whole machine.

[0044] It should be noted that in this embodiment, a through-distributed discharge channel steel 201 is fixedly provided at the bottom of the right side wall of the U-shaped plate 200, and a number of uniformly distributed impurity removal screen holes 202 are opened on the bottom wall of the U-shaped plate 200. The discharge channel steel 201 is used to transport the crushed cotton stalks to the next packaging operation step to realize the orderly discharge of the crushed cotton stalks.

[0045] The first and third conical spiral teeth 104, counting from the front and back, are arranged in a counterclockwise spiral pattern, while the second and fourth conical spiral teeth 104, counting from the front and back, are arranged in a clockwise spiral pattern.

[0046] Several first augers 204 and several fourth augers 210 are alternately staggered, as are several second augers 206 and several third augers 208. The first augers 204, second augers 206, third augers 208 and fourth augers 210 are fixed on the corresponding sleeves and long shafts, respectively. Through different rotation directions and staggered distribution, the cotton stalks entering the U-shaped plate 200 are efficiently crushed in all directions without dead angles.

[0047] The working principle of this embodiment is as follows: When the equipment is running, the first motor 108 serves as the power source. The end of its motor shaft is fixedly connected to the right end of the first fixed roller shaft 102 from front to back. Under the drive of the first motor 108, the fixed roller shaft 102 starts to rotate, thereby driving the conical roller 103 sleeved on it and the conical spiral teeth 104 continuously spirally distributed on the outer surface to rotate synchronously.

[0048] Since the right end of each fixed roller shaft 102 is penetrated by a bent inclined plate 101 and fitted with a concentric fixed gear 105, and adjacent pairs of fixed gears 105 mesh with each other, and the pulleys fitted on the right ends of the second and fourth fixed roller shafts 102 from the front are synchronously connected by a linkage belt 106, this series of transmission structures causes the remaining fixed roller shafts 102, conical rollers 103, and conical spiral teeth 104 to rotate accordingly.

[0049] Among them, the first and third conical spiral teeth 104 from front to back are distributed in a counterclockwise spiral, and the second and fourth conical spiral teeth 104 are distributed in a clockwise spiral. The two pairs of conical spiral teeth 104 have a relative spiral action. Driven by the tractor, the whole machine moves in the cotton stalk field. Each pair of conical spiral teeth 104 follows the corresponding cotton stalk ridge and uses the spiral conveying principle to quickly remove the cotton stalks and convey them into the U-shaped plate 200 along the bending inclined plate 101.

[0050] The cotton stalks entering the U-shaped plate 200 are subjected to crushing by multiple sets of awls. The first sleeve 203, the first long shaft 205, the second sleeve 207, and the second long shaft 209 work together to make several first awls 204 rotate clockwise at high speed, several second awls 206 rotate counterclockwise at high speed, several third awls 208 rotate clockwise at high speed, and several fourth awls 210 rotate counterclockwise at high speed.

[0051] Because several first augers 204 and several fourth augers 210 are alternately staggered, and several second augers 206 and several third augers 208 are alternately staggered, this ingenious layout achieves efficient crushing of cotton stalks in all directions without dead angles.

[0052] During the crushing process, the soil carried by the cotton stalks will fall into the farmland through the evenly distributed impurity removal screen holes 202 on the bottom wall of the U-shaped plate 200, while the crushed cotton stalks will be transported to the next packaging operation step through the discharge channel steel 201 distributed through the bottom of the right side wall of the U-shaped plate 200.

[0053] Example 2: Based on Example 1, this example utilizes a series of precision gears and bevel gears to achieve coordinated operation of several first augers 204 rotating clockwise at high speed, several second augers 206 rotating counterclockwise at high speed, several third augers 208 rotating clockwise at high speed, and several fourth augers 210 rotating counterclockwise at high speed. This ensures efficient crushing of cotton stalks entering the U-shaped plate 200. It also includes:

[0054] In the specific implementation process, such as Figure 7 and Figure 8 As shown, the front end of the first sleeve 203 is fitted with a first gear 211 that is concentrically fixed, and the front end of the second long shaft 209 is fitted with a fourth gear 214 that is concentrically fixed. The first gear 211 and the fourth gear 214 are meshed together. The rear end of the first long shaft 205 is fitted with a second gear 212 that is concentrically fixed, and the rear end of the second sleeve 207 is fitted with a third gear 213 that is concentrically fixed. The second gear 212 and the third gear 213 are meshed together. The first gear 211, the second gear 212, the third gear 213, and the fourth gear 214 are meshed together to further transmit and distribute power, so that the first sleeve 203, the first long shaft 205, the second sleeve 207, the second long shaft 209 and the cutter on them rotate in a predetermined direction to crush the cotton stalks.

[0055] A fixed connecting plate 217 is fixedly provided in the center of the front of the trapezoidal side plate 100. A second through hole is provided at the front end of the fixed connecting plate 217. A second motor 218 with the output end facing upward is fixedly installed inside the second through hole. A fixed bevel gear 219 is sleeved on the end of the motor shaft of the second motor 218. The second motor 218 drives the fixed bevel gear 219 by rotation, thereby driving the subsequent gears and bevel gear transmission to realize the coordinated rotation of multiple sets of cutters.

[0056] The front end of the first sleeve 203 extends forward and is fitted with a first bevel gear 215 that is concentrically fixed. The front end of the first long shaft 205 extends forward and is fitted with a second bevel gear 216 that is concentrically fixed. The second bevel gear 216 and the first bevel gear 215 are located on the front and rear sides of the fixed bevel gear 219, and the fixed bevel gear 219 is meshed with the first bevel gear 215 and the second bevel gear 216 respectively. The fixed bevel gear 219 meshes with the first bevel gear 215 and the second bevel gear 216 to convert and distribute the power of the second motor 218, driving the first bevel gear 215 and the second bevel gear 216 to rotate in opposite directions, providing a power basis for the reverse rotation of different cutters.

[0057] The working principle of this embodiment is as follows: The second motor 218 serves as a new power source, and the concentric fixed bevel gear 219 sleeved on the end of its motor shaft starts to rotate under the drive of the second motor 218; thanks to the ingenious gear transmission design, the fixed bevel gear 219 meshes with the first bevel gear 215 and the second bevel gear 216 located on its front and rear sides, driving the two to rotate in opposite directions.

[0058] The first bevel gear 215 is concentrically fixed to the front end of the first sleeve 203. Its rotation causes the first sleeve 203, a number of first augers 204 evenly distributed on it, and the first gear 211 sleeved at the front end of the first sleeve 203 to rotate synchronously in the forward direction. The first gear 211 meshes with the fourth gear 214, thereby driving the second long shaft 209 concentrically fixed to the fourth gear 214 and a number of fourth augers 210 evenly distributed in the front half of the second long shaft 209 to rotate in the reverse direction.

[0059] At the same time, the second bevel gear 216 is concentrically fixed to the front end of the first long shaft 205. Its rotation drives the first long shaft 205, a number of second cutters 206 evenly distributed on it, and the second gear 212 sleeved at the rear end of the first long shaft 205 to rotate in the opposite direction. The second gear 212 meshes with the third gear 213, thereby driving the second sleeve 207 concentrically fixed to the third gear 213 and a number of third cutters 208 evenly distributed in the front half of the second sleeve 207 to rotate in the forward direction.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
