Abstract

The present invention discloses a four-roller cotton stalk pulling and kneading device, which comprises a frame, which is a square frame structure. A soil crushing mechanism, a reed roller, a pulling mechanism and a kneading mechanism are sequentially arranged along the length direction of the frame. When working, the soil crushing mechanism is used to crush the soil at the root of the cotton stalk, so that the cotton stalk falls toward the direction close to the reed roller. The driving motor can drive the reed roller to rotate downward around the axis of the reed roller toward the direction close to the soil crushing mechanism through a transmission system, so that the cotton stalk is transmitted to the pulling mechanism by the reed roller. At the same time, the pulling mechanism can pull up the cotton stalk by rotating around the axis of the pulling mechanism, and finally the cotton stalk is kneaded and filamented by the kneading mechanism.

Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a four-roller cotton stalk pulling and kneading device. Background Art

[0002] Cotton straw is an important agricultural biomass resource with high recycling value. It can be used as raw material for power generation, papermaking, feed, etc. However, the current cotton stalk recycling rate is less than 1 / 10 of the total output, and most of the recycling is done by manual picking, which is labor-intensive, costly, and extremely low in productivity.

[0003] At present, the main way to deal with cotton stalks in China is to directly crush them and return them to the fields. However, the stubble left in the fields is not easy to rot in the soil, and the roots of cotton often host a large number of pathogens, which will not only affect the quality of operations such as residual film recovery, sowing and film laying, but also greatly increase the incidence of diseases and pests in cotton fields. Therefore, the cotton stalks must be uprooted.

[0004] In the existing technology, there is still a lack of whole-plant cotton stalk pulling devices on the market. Some devices under development have low operating efficiency and cannot meet the needs of large-scale cotton cultivation in Xinjiang. Although some devices can pull out cotton, the pulling rate of the devices is low, and a considerable number of cotton stalks will still remain in the soil. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention uses a coordinated design of a soil crushing mechanism and a sowing roller to first crush the soil at the roots of the cotton stalks and guide the cotton stalks to fall. The soil crushing pretreatment can significantly reduce the resistance to stalk pulling and reduce energy consumption. Then, a four-roller pulling-kneading mechanism is used to complete the integrated operation of pulling out, conveying and kneading. The structure of the sowing roller is further improved, and the V-groove blade design can accurately guide the cotton stalks into the pulling-up mechanism. Compared with similar transmission structures, it can effectively reduce the problem of missed pulling in traditional equipment during row operations. The double-roller gap design in the pulling-up mechanism and the kneading mechanism ensures that the cotton stalks can be pulled up as a whole plant, and at the same time, the cotton stalks after the whole plant is pulled up can be kneaded in multiple stages to make them soft filaments, which are beneficial to ruminants' feeding and digestion, and are also convenient for subsequent further processing, solving the problem that the subsequent utilization and processing of the cotton stalks are more difficult due to the high degree of lignification. Compared with existing equipment, the present invention can better adapt to the processing needs of cotton stalks of different thicknesses.

[0022] 2. The present invention adopts a transmission system consisting of a reversing gear box and a multi-stage belt, which drives the plowing roller, upper and lower pulling rollers, and upper and lower rubbing rollers to operate synchronously in sections through the reversing gear box and the transmission system; compared with other equipment in the prior art, the present invention has a more stable mechanical transmission structure while minimizing the number of parts and simplifying the equipment structure, and dynamically adjusts the distance between the upper pulling roller and the lower pulling roller through a floating mechanism, which can adapt to the traction requirements of cotton stalks of different diameters and reduce the risk of jamming; at the same time, the height adjustment mechanism of the plowing roller can adjust the operating depth according to the field terrain, which is more flexible and is particularly suitable for complex plots.

[0023] 3. The frame of the present invention adopts a square frame and a detachable soil-breaking blade design, which is convenient for replacing worn parts, and the belt groove design of the transmission system avoids interference between multiple belts and improves transmission efficiency; at the same time, the four-roller structure (upper / lower pulling rollers + upper / lower rubbing rollers) reduces the load of a single component through segmented processing and extends the service life; ultimately, it solves the problems of reducing pulling resistance, pulling out the entire cotton stalk, and rubbing the cotton stalk, and has the function of adjustable soil crushing mechanism. The modules of the whole machine are closely connected, the power consumption is small, the reliability is high, and it can meet the different requirements of cotton stalk pulling.

DETAILED DESCRIPTION

[0030] The present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments derived by persons of ordinary skill in the art based on the present invention are within the scope of protection of the present invention.

[0031] Unless otherwise indicated in specific cases, the numerical ranges listed herein include the upper and lower limits, and all integers and fractions within the range, and are not limited to the specific values ​​listed when defining the range.

[0032] The present invention provides a four-roller cotton stalk pulling and kneading device, such as Figures 1 to 5 As shown, it includes a frame 1, a soil crushing mechanism, a reel roller 2, a pulling mechanism and a kneading mechanism; wherein the frame 1 is a square frame structure; the soil crushing mechanism is located at one end of the frame 1 along its length direction and is detachably fixedly connected to the frame 1; a plurality of tires 3 for movement are provided at the other end of the frame 1 along its length direction; the reel roller 2 is located on the frame 1, close to the soil crushing mechanism, and the roller shafts at both ends of the reel roller 2 are respectively connected to the frame 1 for rotation; the pulling mechanism is located between the reel roller 2 and the tire 3, close to the side of the reel roller 2, and is connected to the frame 1 for rotation; the kneading mechanism is located between the pulling mechanism and the tire 3, close to the side of the pulling mechanism, and is connected to the frame 1 for rotation;

[0033] The frame is also provided with a transmission system and a reversing system, and the reed roller 2, the pulling mechanism and the kneading mechanism are connected to the drive mechanism through the transmission system and the reversing system, so that the drive mechanism can simultaneously drive the reed roller, the pulling mechanism and the kneading mechanism to rotate;

[0034] During operation, the soil crushing mechanism is used to crush the soil at the roots of the cotton stalks, causing the cotton stalks to fall toward the direction close to the reed roller; the driving mechanism can drive the reed roller to rotate downward toward the direction close to the soil crushing mechanism through the reversing system and the transmission system, so that the reed roller transfers the cotton stalks close to the reed roller to the pulling-up mechanism; at the same time, after the pulling-up mechanism pulls up the cotton stalks, it transfers them to the kneading mechanism to knead the cotton stalks. In actual application, the device of the present invention can perform cotton stalk pulling operations under the traction of a traction vehicle. The device is detachably and fixedly connected to the traction vehicle. The driving mechanism can be provided with a separate driving motor, or it can be driven by the traction vehicle's drive system in conjunction with the reversing system. The present invention does not limit the type of traction vehicle. Various agricultural or other vehicles can be used in the present invention. Here, a tractor commonly used in agriculture is used as an example. The rear power output shaft of the tractor is first connected to the reversing system for rotation, and then connected to the transmission system for transmission, so that the rear output shaft of the tractor can simultaneously drive the sowing roller, the pulling-up mechanism and the kneading mechanism to rotate through the reversing system and the transmission system. The rear output shaft of the tractor can drive the sowing roller to rotate downward around the axis of the sowing roller toward the direction close to the soil crushing mechanism through the transmission system, so that the cotton stalks are transmitted from the bottom of the sowing roller to the pulling-up mechanism by the inertia of the sowing roller; at the same time, the pulling-up mechanism can firmly clamp the cotton stalks through relative rotation and then pull up the whole plant, and then the kneading mechanism can knead the cotton stalks through relative rotation, finally realizing the pulling out and kneading of the whole cotton stalk.

[0035] In some embodiments of the present invention, Figure 1 As shown, a traction frame 4 is further provided at one end of the frame 1 near the soil crushing mechanism. The traction frame 4 is located above the soil crushing mechanism and is fixedly connected to the frame 1 for detachable connection to a traction vehicle. In actual use, the traction vehicle can be detachably fixedly connected to the pulling and kneading device via the traction frame. For example, the traction frame can be connected to the traction vehicle via a three-point suspension, and then drive the pulling and kneading device to pull and knead the cotton stalks.

[0036] In some embodiments of the present invention, Figure 1As shown, the soil-crushing mechanism includes multiple blades 5, evenly spaced along the width of the frame 1. One end of each blade 5 is detachably connected to the frame 1, and the other end is bent away from the frame 1 and then extends downward to form a scraping end. The position of the blades 5 at the front end of the frame 1 and their height can be adjusted according to the actual cotton planting situation. The blades 5 function to break up the soil at the base of the cotton stalks. Simultaneously, by using the downward scooping action, they lift the cotton stalks and cause them to fall toward the reel rollers. This ensures that the cotton stalks can smoothly enter under the reel rollers and, under the rotation of the reel rollers, enter the lifting mechanism, thereby lifting the cotton stalks. Most existing double-roller lifting devices utilize a non-moving soil lifting method, lacking a soil-crushing mechanism. This results in greater resistance to cotton stalk lifting, and significant stalk breakage and missed stalks. The blades of the present invention not only break up the soil at the base of the cotton stalks, reducing the lifting resistance, but also further ensure the falling direction of the cotton stalks, ensuring that as many stalks as possible fall toward the reel rollers, thereby lifting the majority of the stalks.

[0037] In some embodiments of the present invention, Figures 1 and 2 As shown, the reel roller 2 is located on the side of the blade 5 away from the shoveling end, and the two ends of the reel roller 2 are rotatably connected to the frame 1 on opposite sides along its width direction, so that the axis of the reel roller 2 and the length direction of the frame 1 are perpendicular to each other; the roller shaft at one end of the reel roller 2 is fixedly connected to the transmission system, so that the drive mechanism can drive the reel roller to rotate downward around the axis of the reel roller toward the soil crushing mechanism through the reversing system and the transmission system.

[0038] In some embodiments of the present invention, Figures 1 and 2 As shown, a plurality of sowing blades 6 are provided on the sowing roller 2, and the sowing blades 6 are evenly distributed along the circumference of the sowing roller 2; the length direction of the sowing blades 6 is parallel to the axial direction of the sowing roller 2, and the sowing blades 6 are fixedly connected to the sowing roller 2 along one side of their length direction, so that a V-shaped groove is formed between two adjacent sowing blades 6, so that the cotton stalks can be placed on the outside of the sowing blades, thereby ensuring that the cotton stalks can enter the pulling mechanism under the transportation of the sowing roller.

[0039] In some embodiments of the present invention, Figure 3As shown, two height adjustment mechanisms are respectively provided at both ends of the plowing roller 2 along its length direction, and the height adjustment mechanism includes a fixing frame 7 and a plurality of adjusting screws 8; wherein the adjusting screws 8 are spaced apart along the length direction of the fixing frame 7, and one end of the adjusting screw 8 passes through the fixing frame 7 and extends into a sleeve and is threadedly connected to the sleeve, and the bottom end of the sleeve is fixedly connected to the frame; a fixed bearing seat 9 is provided above the other end of the adjusting screw 8, and the bottom of the fixed bearing seat 9 is rotatably connected to the adjusting screw 8, and the roller shaft of the plowing roller 2 is fixedly connected to the transmission system after passing through the fixed bearing seat 9; an adjusting nut 10 is sleeved on the adjusting screw 8, and the adjusting nut 10 is threadedly connected to the adjusting screw 8, and the bottom of the adjusting nut 10 abuts against the fixing frame 7. Rotating the adjusting nut 10 can make the adjusting screw move up and down along the length direction of the sleeve, thereby adjusting the height of the plowing roller so that it can meet the needs of plucking cotton stalks of different heights.

[0040] In some embodiments of the present invention, Figures 1 and 2As shown, the pulling mechanism includes an upper pulling roller 11 and a lower pulling roller 12; wherein, the upper pulling roller 11 is located between the reed roller 2 and the tire 3, and is located below the reed roller 2 on the side close to the tire 3, the axis of the upper pulling roller 11 is parallel to the axis of the reed roller 2, and the two ends of the upper pulling roller 11 are respectively connected to the opposite sides of the frame 1 along the width direction thereof for rotation; the lower pulling roller 12 is located below the upper pulling roller 11 and close to the side of the tire 3, the axis of the lower pulling roller 12 is parallel to the axis of the upper pulling roller 11, and the lower pulling roller 12 is connected to the opposite sides of the frame 1 along the width direction thereof. The two ends are respectively connected to the opposite sides of the frame 1 along its width direction; there is a gap I between the outer surface of the upper pulling roller 11 on the side close to the lower pulling roller 12 and the outer surface of the lower pulling roller 12 on the side close to the upper pulling roller 11. The size of the gap I should not be too large. When the cotton stalk enters the gap I between the upper pulling roller 11 and the lower pulling roller 12, the upper pulling roller 11 and the lower pulling roller 12 can squeeze the cotton stalk, thereby exerting a force to pull the cotton stalk upward. If the gap I is too large, it will cause the cotton stalk to slip between the upper pulling roller and the lower pulling roller and cannot play a pulling role. However, the size of the gap I can be adjusted accordingly according to the size of the cotton stalk stem to meet the pulling needs of different varieties of cotton stalks. The roller shafts of the upper pulling roller and the lower pulling roller on the same side of the frame are respectively fixedly connected to the transmission system. When working, the upper pulling roller and the lower pulling roller have opposite rotation directions. In short, the upper pulling roller rotates downward toward the direction close to the reel roller, and the lower pulling roller rotates upward toward the direction close to the reel roller. This enables the upper pulling roller and the lower pulling roller to firmly clamp the cotton stalks conveyed by the reel roller on the side facing the reel roller, and then through further rotation, exert downward and upward pressure on the upper and lower parts of the cotton stalks at the same time, thereby pulling up the cotton stalks and ensuring that the cotton stalks will not slip out of the pulling mechanism. At the same time, it is precisely because the upper pulling roller and the lower pulling roller rotate relative to each other that the upper pulling roller and the lower pulling roller rotate toward each other on the side close to the reel roller, squeezing the cotton stalks while also conveying them toward the tire, and finally transmitting the pulled-up cotton stalks to the rubbing mechanism.

[0041] In some embodiments of the present invention, Figure 5 As shown, in order to better demonstrate the connection structure between the floating mechanism and the upper pulling roller, Figure 5The second driven wheel 23 connected to the upper pulling roller 11 is removed, and a floating mechanism is provided at the end of the upper pulling roller 11 close to the transmission system; the floating mechanism includes a floating rod 13, a floating spring 14 and a pressing plate 15; the pressing plate 15 is located above the upper pulling roller 11, one end of the pressing plate 15 is fixedly connected to the frame 1, and the other end is provided with an opening, the aperture of which is much larger than the rod diameter of the connecting rod 17, which does not affect the movement of the connecting rod 17; a connecting bearing seat 16 is provided at one end of the floating rod 13, and the connecting bearing seat 16 is provided at the bottom of the floating rod 13. The seat 16 is sleeved on the outside of the rotating shaft of the upper pulling roller 11 and is fixedly connected to the floating rod 13; a connecting rod 17 is provided at the other end of the floating rod 13, and the length direction of the connecting rod 17 is perpendicular to the length direction of the floating rod 13. One end of the connecting rod 17 is fixedly connected to the floating rod 13, and the other end passes through the opening on the pressing plate 15 and continues to extend in the direction away from the pressing plate 15; the floating spring 14 is sleeved on the connecting rod 17, and one end of the floating spring 14 is fixedly connected to the floating rod 13, and the other end is fixedly connected to the pressing plate 15. In actual implementation of the present invention, it was found that the pulling mechanism may use too much force when pulling up the cotton stalks, resulting in excessive damage to the cotton stalks, so that the cotton stalks are not pulled up as a whole and some of them remain in the ground. For this reason, the present invention designs a floating mechanism. When a large number of cotton stalks enter between the upper pulling roller and the lower pulling roller, the cotton stalks will also squeeze the upper pulling roller, thereby causing the upper pulling roller to be subjected to an upward force in the vertical direction. At this time, the floating rod 13 in the floating mechanism will move upward with the upper pulling roller. However, under the action of the pressing plate and the floating spring, the upper pulling roller will still exert a downward force on the cotton stalks, but this force will be much smaller than that of a completely fixed upper pulling roller, and this force can be automatically adjusted according to the thickness of the cotton stalks entering between the upper and lower pulling rollers. If the upper pulling-up roller is completely fixed and a large number of cotton stalks enter between the upper and lower pulling-up rollers, the force between the upper and lower pulling-up rollers will be too large and the cotton stalks will be directly clamped and broken, thereby causing some cotton stalks to be unable to be pulled up as a whole plant and remain in the soil. The floating mechanism designed in the present invention can provide a buffer while ensuring the pulling-up force of the cotton stalks, avoiding excessive damage to the cotton stalks, ensuring that the cotton stalks can be pulled up as a whole plant, and minimizing the amount of cotton stalks remaining in the soil.

[0042] In some embodiments of the present invention, Figures 2 and 3As shown, it also includes a kneading mechanism; the kneading mechanism includes an upper kneading roller 18 and a lower kneading roller 19, the upper kneading roller is located above the upper pulling roller on the side close to the tire, and the lower kneading roller is located below the upper kneading roller and above the lower pulling roller on the side close to the tire. The axes of the upper kneading roller and the lower kneading roller are parallel to the axis of the reed roller; the two ends of the upper kneading roller along its length direction are respectively connected to the opposite sides of the frame along its width direction for rotation, and the two ends of the lower kneading roller along its length direction are respectively connected to the opposite sides of the frame along its width direction for rotation; there is a gap II between the outer surface of the upper kneading roller on the side close to the lower kneading roller and the outer surface of the lower kneading roller on the side close to the upper kneading roller; the roller shafts of the upper and lower kneading rollers on the same side of the frame are respectively fixedly connected to the transmission system; the driving mechanism drives the upper kneading roller to rotate downward toward the reed roller through the transmission system, and at the same time, the lower kneading roller rotates upward toward the reed roller. When the upper pulling roller, the lower pulling roller, the upper kneading roller and the lower kneading roller rotate simultaneously, the upper pulling roller, the upper kneading roller and the reeding roller rotate in the same direction; the lower pulling roller rotates in the same direction as the lower kneading roller and in the opposite direction to the reeding roller. Most existing cotton stalk pulling devices only have the function of pulling out the whole cotton stalk, and lack the cotton stalk post-processing process. Since the cotton stalk has a high degree of lignification, kneading the cotton stalk can make it soft and filamentous, which is beneficial for ruminants to eat and digest, and also facilitates subsequent further processing. Therefore, the present invention is provided with a kneading mechanism, and the upper and lower kneading rollers in the kneading mechanism rotate in opposite directions, thereby forming a downward pulling force on the cotton stalks entering the gap II, and further applying a kneading force to the pulled cotton stalks, so that they can be better used for subsequent feed processing.

[0043] In some embodiments of the present invention, Figures 2-4As shown, the reversing system comprises a reversing gearbox 20, located between the soil crushing mechanism and the reed rollers and fixedly connected to the frame. The reversing gearbox comprises a transmission shaft and a drive shaft. The drive shaft is fixedly connected to the drive end of the drive mechanism, and the drive shaft is fixedly connected to the transmission system. This allows the drive end of the drive mechanism to simultaneously drive the reed rollers, the pulling mechanism, and the kneading mechanism through the reversing gearbox and the transmission system. In actual use, the reversing gearbox can be a 90° reversing gearbox, so that the longitudinal direction of the drive shaft and the longitudinal direction of the transmission shaft form a 90° angle. The transmission system comprises a first driving wheel 21, a first driven wheel 22, a second driven wheel 23, and a third driven wheel 24. The first driving wheel 21, the first driven wheel 22, the second driven wheel 23, and the third driven wheel 24 are all located on the same side of the frame, that is, the first driving wheel 21, the first driven wheel 22, the second driven wheel 23, and the third driven wheel 24 are all located on the same plane. The first driving wheel 21 is fixedly connected to the transmission shaft of the reversing gear box 20, so that the first driving wheel 21 can rotate around the axis of the first driving wheel 21 under the drive of the reversing gear box 20. The first driven wheel 22 is located at one end of the plowing roller 2 and is fixedly connected to its roller shaft. The second driven wheel 23 is located at one end of the upper pulling roller 11 and is fixedly connected to its roller shaft. The third driven wheel 24 is located at one end of the upper rubbing roller 18 and is fixedly connected to its roller shaft. One end of the first driving belt 25 is sleeved on the outside of the first driving wheel 21, and the other end is sleeved on the outside of the first driven wheel 22. One end of the first driven belt 26 is sleeved on the outside of the first driven wheel 22, and the other end is sleeved on the outside of the second driven wheel 23. One end of the second driven belt 27 is sleeved on the outside of the second driven wheel 23, and the other end is sleeved on the outside of the third driven wheel 24. A belt groove I and a belt groove II are provided on the outer surface of the first driven pulley 22. Both belt grooves I and II are arranged circumferentially along the first driven pulley 22 and are spaced apart along the length of the first driven pulley 22. A first driven belt 25 is positioned within belt groove I, and a second driven belt 26 is positioned within belt groove II. This prevents interference between the first driven belt 25 and the second driven belt 26 on the outer sides of the first driven pulley 22 and the second driven pulley 23 due to displacement. This simplifies the structure of the equipment, improves the stability of the transmission system, facilitates maintenance and overhaul, and reduces operating costs. When the driving mechanism drives the first driving wheel 21 to rotate around the axis of the first driving wheel 21 through the reversing gear box, the first driving wheel 21 can simultaneously drive the first driven wheel 22 to rotate synchronously through the first driving belt 25, the first driven wheel 22 drives the second driven wheel 23 to rotate synchronously through the first driven belt 26, and the second driven wheel 23 drives the third driven wheel 24 to rotate synchronously through the second driven belt 27, thereby causing the plowing roller 2, the upper pulling roller 11 and the upper kneading roller 18 to rotate around their respective axes at the same time, and the rotation directions of the plowing roller 2, the upper pulling roller 11 and the upper kneading roller 18 are consistent.When not in operation, the reversing gearbox 20 has no rotational restrictions. When in operation, the drive shaft of the reversing gearbox 20 rotates downward toward the soil crushing mechanism, causing the reed roller 2 to rotate downward toward the reversing gearbox 20. As cotton stalks fall toward the reed roller 2, the rotation of the reed roller 2 drives the stalks toward the pull-up mechanism, whereupon they enter the pull-up mechanism. The first driving wheel 21, the first driven wheel 22, the second driven wheel 23, and the third driven wheel 24 ensure that the reed roller 2, the upper pull-up roller 11, and the upper kneading roller 18 rotate in the same direction. The transmission system further includes a second driving wheel 28, a fourth driven wheel 29, a fifth driven wheel 30, a reversing wheel 31 and a tensioning wheel 32, and the second driving wheel 28, the fourth driven wheel 29, the fifth driven wheel 30, the reversing wheel 31 and the tensioning wheel 32 are all located on the side of the frame 1 away from the first driving wheel 21; wherein the second driving wheel 28 is located at the other end of the upper pulling roller 11 away from the second driven wheel 23, and is fixedly connected to the roller shaft of the upper pulling roller 11; the fourth driven wheel 29 The fifth driven wheel 30 is fixedly connected to the roller shaft of the lower pulling roller 12 at the end away from the first driving wheel 21, and the fifth driven wheel 30 is fixedly connected to the roller shaft of the lower rubbing roller 19 at the end away from the first driving wheel 21; the reversing wheel 31 is rotatably connected to the frame 1 through the bearing seat, and is located between the fourth driven wheel 29 and the tire 3 and below the fifth driven wheel 30; the tensioning wheel 32 is located below the second driving wheel 28 and on the side of the fourth driven wheel 29 close to the plowing roller 2, and is rotatably connected to the frame 1; the second driving belt One end of the third driven belt 33 is sleeved on the outside of the second driving pulley 28, and the other end extends downward and sleeved on the outside of the reversing pulley 31, then passes around the fourth driven pulley 29 close to the outer wall of the second driving pulley 28 and is sleeved on the outside of the tensioning pulley 32; one end of the third driven belt 34 is sleeved on the outside of the fourth driven pulley 29, and the other end is sleeved on the outside of the fifth driven pulley 30; a belt groove III and a belt groove IV are also provided on the outside of the fourth driven pulley 29; the belt groove III and the belt groove IV are both arranged along the circumference of the fourth driven pulley 29, and the belt groove III and the belt groove IV are spaced apart along the length direction of the fourth driven pulley 29; the second driving belt 33 is located in the belt groove III, and the third driven belt 34 is located in the belt groove IV, which can prevent the second driving belt and the third driven belt on the outside of the fourth driven pulley from interfering with each other due to displacement, thereby simplifying the equipment structure while improving the stability of the transmission system, facilitating maintenance and overhaul, and reducing the cost of use. When the upper pulling roller 11 rotates, the upper pulling roller can drive the second driving wheel to rotate together. At the same time, the second driving wheel 28 drives the lower pulling roller 12 to rotate around the axis of the lower pulling roller through the second driving belt 33, thereby realizing the opposite rotation of the upper and lower pulling rollers. The lower pulling roller 12 drives the lower rubbing roller 19 to rotate around the axis of the lower rubbing roller through the third driven belt 34, thereby realizing the opposite rotation of the upper and lower rubbing rollers 18 and 19.When designing the transmission system, the present invention found that the transmission system of the prior art often has problems such as complex structure, large number of parts and poor stability when trying to achieve the effects described in the present invention. Therefore, the present invention not only needs to consider the stability of the entire device, but also needs to consider simplifying the equipment as much as possible to facilitate maintenance and maintenance by operators, thereby reducing actual application costs and facilitating the promotion and application of the present invention. For this reason, the present invention unexpectedly found that the use of the transmission system described in the present invention can not only achieve the purpose of the present invention, but also the stability of the entire device in actual application is very good. Even if a fault occurs, the operator can quickly perform repairs without the need for additional training for the operator, and has good application prospects.

[0044] Compared with the existing cotton stalk whole-plant pulling-out device, the present invention combines the three functions of breaking the soil at the roots of the cotton stalks, pulling out the whole cotton stalks, and kneading the cotton stalks. While ensuring the structural completion of the whole cotton stalk, it has a high cotton stalk pulling-out rate, and realizes the integrated operation of pulling out the whole cotton stalks and kneading. The device of the present invention and the cotton stalk pulling-out device currently available on the market were actually operated in fields of the same area and the same number of cotton stalks planted. The comparison was made by calculating the number of cotton stalks pulled out and the ratio of the number of broken cotton stalks to the total number of cotton stalks planted. The results of the field test showed that the cotton stalk pulling-out rate of the present invention was 95%, and the breaking rate was 2%, while the pulling-out rate of the existing cotton stalk pulling device was generally 80%-90%, and the breaking rate was about 5%. Therefore, the present invention has a higher pulling-out rate and cotton stalk integrity than the existing device.

[0045] The present invention works as follows:

[0046] The device of the present invention adopts a three-point rear suspension operation mode of the tractor. During operation, the multiple groups of soil crushing mechanisms at the front of the device are aligned with the cotton stalk rows respectively. When the tractor drives the device forward, the two adjacent soil crushing knives in each group of soil crushing mechanisms crush and loosen the soil on both sides of the cotton stalk row. The power of the rear output shaft of the tractor is transmitted to the reversing gear box through the universal joint transmission shaft. The reversing gear box drives the first driving wheel to rotate through the driving shaft. The first driving wheel drives the first driven wheel to rotate through the first driving belt, and then drives the reed roller to rotate. The rotation of the reed roller applies a lodging force to the cotton stalks, causing the cotton stalks to lodging in the direction of the lifting gap formed by the upper and lower lifting rollers; the first driven wheel drives the second driven wheel to rotate through the first driven belt, and the reed roller rotates. The upper pulling roller is driven to rotate, and the second driving wheel at the other end of the upper pulling roller drives the lower pulling roller to rotate through the second driving belt. The upper pulling roller and the lower pulling roller rotate in opposite directions, exerting a pulling force on the cotton stalks fed between the two rollers, and pulling the whole cotton stalk out of the soil; the upper pulling roller drives the second driven wheel to rotate, and the second driven wheel drives the third driven wheel to rotate through the second driven belt, thereby driving the upper rubbing roller to rotate, and the lower pulling roller drives the fourth driven wheel at one end thereof to rotate, and the fourth driven wheel drives the fifth driven wheel to rotate through the third driven belt, thereby driving the lower rubbing roller to rotate, and the upper rubbing roller and the lower rubbing roller rotate in opposite directions, and the two rubbing rollers exert squeezing and rubbing force on the pulled cotton stalks, and rub the cotton stalks to facilitate subsequent feed and other uses.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the technical solutions. Those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present invention that do not depart from the purpose and scope of the technical solutions of the present invention should be included in the scope of the claims of the present invention.
