Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to an all-in-one machine for recycling residual film and returning straw to fields. Background Art

[0002] The film mulching planting technology has been widely promoted and applied in Xinjiang due to its advantages of increasing income efficiently, increasing temperature and retaining moisture. However, the residual film after use has not been effectively recycled year after year, causing serious residual film pollution to farmland.

[0003] In order to solve the serious white pollution problem caused by the increase in the use of ground film, more and more people have begun to develop and research residual film picking and recycling machinery to solve the problems of low manual recycling efficiency, low net collection rate, high labor intensity and high cost.

[0004] In addition, crushing and returning crop straw to the field is beneficial to increasing the organic matter and nutrient content of the soil, improving the physical properties of the soil, and increasing the biological activity of the soil, which has a significant effect on increasing production. Crushing and returning crop straw to the field is a labor-intensive, time-consuming, and highly seasonal operation. If crop straw is not handled in time, it will affect the autumn plowing of the farmland and restrict the spring sowing production next year. At present, straw crushers are used to crush crop straw and return it to the field, and then plowed and buried in the soil.

[0005] After the crops are harvested, the residual film on the ground needs to be removed in time to facilitate the growth of crops in the next year. At present, the main method used is a spring-tooth film rake to remove the residual film on the ground. The rake principle is used to rake the residual film on the ground into piles or strips, and then load it onto a truck and transport it out of the field. This method easily removes the crushed straw that is returned to the field at the same time, which loses the effect of returning the straw to the field, and the residual film removal rate and productivity are low.

[0006] In the prior art, film cleaning and straw shredding and returning to the field are performed separately, which requires many operations and consumes a lot of power. In order to complete the shredding and returning to the field and the residual film recovery in one operation, reduce the operation links, and reduce the production cost, the present invention provides a combined operation machine for residual film picking, packaging and recovery and straw shredding and returning to the field, so as to achieve combined operation and multiple uses of one machine. Summary of the invention

[0007] The purpose of the present invention is to provide a structurally reasonable, economical and practical all-in-one machine for recovering residual film and returning straw to the field, which can realize the combined operation of picking up residual film, recycling and packaging, and crushing and returning straw to the field, and one machine has multiple uses; when in use, the residual film picking roller has a smaller burden during the picking process, which can effectively increase the overall flexibility of the picking roller and greatly improve the efficiency of the residual film picking operation; a special suspension traction frame is used to solve the practical problem that the angle formed between the power input and the transmission shaft is too small, which is not conducive to the backward transmission of the locomotive, and the steering and transmission can be flexibly connected between the traction locomotive and the operating agricultural machinery; the design of multiple gear boxes in the transmission device and the design of the clutch sprocket make the transmission deceleration faster and the transmission more stable, ensuring the coordinated and normal operation of all components of the whole machine.

[0008] The present invention discloses an integrated machine for recovering residual film and returning straw to the field, comprising a main frame, a traction frame and walking wheels.

The inner rail assembly and the outer rail assembly are spaced apart to form an irregularly shaped annular track.

[0011] In the track plate device structure, the structure of the inner rail assembly includes an upper inner rail plate and a middle inner rail plate. The upper inner rail plate and the middle inner rail plate have the same shape, both of which are irregular annular plates. The middle inner rail plate, the upper inner rail plate and the end plate are fixed by bolts, and a spacer sleeve is provided on the bolt, so that the middle inner rail plate, the upper inner rail plate and the end plate are separated by a distance from top to bottom.

[0012] The structure of the outer rail assembly includes an upper outer rail plate and a middle outer rail plate. The upper outer rail plate and the middle outer rail plate have the same shape and are both irregular annular plates. The middle outer rail plate, the upper outer rail plate and the end plate are fixed by bolts, and a spacer sleeve is provided on the bolt, so that the middle outer rail plate, the upper outer rail plate and the end plate are separated by a distance from top to bottom.

[0013] In the track plate device structure, the bolts are divided into long installation bolts and short installation bolts. The long installation bolts extend outward for a section to fix the end plate to the main frame.

[0014] The traction frame mainly comprises a main support, a suspension connection frame, and a U-shaped connection support, one end of the U-shaped connection support is hinged to the middle of the suspension connection frame, and the other end of the U-shaped connection support is hinged to the main support; A "п"-shaped slide is provided above the U-shaped connecting support, and a strip slide is provided on the "п"-shaped slide. A transmission support is provided at the end of the main support close to the U-shaped connecting support. The transmission support is divided into an upper support and a lower support. The upper support and the lower support are both tubular cylinders. A rotating shaft is provided in the lower support, and the upper part of the rotating shaft is connected to the lower support through a bearing, and the lower part of the rotating shaft is fixedly connected to the main support; the upper support is arranged horizontally, and a transmission coupling is provided inside, and the transmission coupling is connected to the upper support through a bearing.

[0015] The front part of the transmission support is provided with a forward-extending sliding wall, the front end of which is provided with a pulley, the pulley extends into the strip-shaped sliding groove on the "п"-shaped sliding seat, and the pulley can slide back and forth in the strip-shaped sliding groove.

[0016] An anti-vibration seat is arranged at the rear of the transmission support, and an anti-vibration block is arranged at the front end of the anti-vibration seat. The anti-vibration block extends forward and is in elastic contact with the outer wall of the lower support.

[0017] In the traction frame structure, reinforcing ribs are provided on the sliding wall; the shockproof seat is a tubular cylinder, the shockproof block is connected to a block seat, the block seat is slidably connected to the inner wall of the shockproof seat, and the upper and rear parts of the shockproof seat are provided with tightening nuts, the tightening nuts pass through the outer wall of the shockproof seat, contact the block seat, and tighten the block seat downward and forward.

[0018] In the traction frame structure, the anti-seismic block is made of elastic material; the contact surface between the anti-seismic block and the outer wall of the lower support is in the shape of an arc surface.

[0019] The rod beating device is arranged at the front end of the main frame, and its structure includes a throwing air duct. The throwing air duct is in the shape of a flat tent-like air duct, extending backward to cover the top of the whole machine, and its function is to throw the crushed straw to the rear of the whole machine.

[0020] The residual film picking roller is arranged behind the rod beating device, and a windproof curtain is arranged between the two. The structure of the windproof curtain includes a baffle plate, a baffle plate cross arm, and a curtain plate seat. The baffle plate is a folding plate, and the baffle plate cross arm is arranged at the upper end of the baffle plate and connected to the main frame through the curtain plate seat. The function of the windproof curtain is to prevent the airflow driven by the rod beating device in the front from affecting the picking operation of the residual film picking roller in the rear.

[0021] The structure of the transmission device includes a locomotive speed input end, a transmission shaft I, a rod beating device gear box, a bridge gear box, a transmission shaft II, a residual film picking roller gear box, a fan input sprocket, a fan output sprocket, a bridge seat, a clutch sprocket, a bridge shaft, and a packaging device input sprocket; external power is transmitted to the transmission shaft I through the locomotive speed input end, the transmission shaft I is connected to the rod beating device gear box, and then transmitted to the bridge gear box through a belt, the bridge gear box then transmits the power to the residual film picking roller gear box through the transmission shaft II, and then transmits it to the residual film picking roller sprocket through a chain drive, and is output to the fan input sprocket after speed change, and the power is then transmitted to the packaging device input sprocket in sequence through the fan output sprocket, the bridge seat, the clutch sprocket, and the bridge shaft.

[0022] The present invention utilizes a gear box to reduce speed, thus overcoming the problem in the commonly used belt drive design that the belt drive has a relatively slow deceleration and often requires several stages of deceleration to reduce the speed, resulting in a slow process and a relatively complicated structural design. The present invention is designed so that the gear box reduces speed in one step, thus greatly simplifying the combined design of the transmission device.

[0023] The clutch sprocket in the transmission device comprises a single-row sprocket and a clutch disc. The diameter of the clutch disc is smaller than that of the single-row sprocket. The clutch disc is fixedly sleeved with the bridge shaft. The single-row sprocket is provided with a plurality of connecting bolt holes around the shaft hole. The clutch disc is also provided with a plurality of bolt holes at matching positions. The single-row sprocket and the clutch disc are coaxially engaged with each other and are connected by bolts. The number of bolts is smaller than the number of bolt holes, so that when subjected to stress overload or unstable stress, the connecting bolts between the single-row sprocket and the clutch disc are disconnected, thereby ensuring that the single-row sprocket and the clutch disc are disconnected.

[0024] The clutch sprocket plays a key role in protecting machine components: during the packaging operation of the locomotive, when the packaging device at the rear is overloaded, the operation must be stopped in time. If it is not stopped in time, it will cause wear and damage to the components. At this time, the connecting bolts between the single-row sprocket and the clutch plate are twisted off, resulting in idling, and the packaging device stops working, effectively avoiding damage to mechanical parts.

[0025] Preferably, the single-row sprocket and the clutch disc are connected by bolts, and the number of bolts is 2-4.

[0026] Preferably, two sets of depth-limiting rollers are provided below the main frame, which are respectively located behind the rod-beating device and behind the residual film picking roller.

[0027] Working principle of the present invention: The present invention integrates stalk cutting and returning to the field, residual film picking up, and residual film recovery and packaging into one, realizing the combined operations of residual film picking up, recovery and packaging, and straw crushing and returning to the field. In the design of the whole machine, the existing pole beating device and residual film packaging device in the prior art can be used.

[0028] In the prior art, there is a spring-tooth type residual film picking roller which drives a spring-tooth mounting rod to rotate through a driving device, wherein the driving device includes a track plate or a cam plate to drive a crank or a crank arm mechanism, which finally rotates the film picking spring teeth installed on the spring-tooth mounting rod, wherein the track plate is an integrally closed plate body, and the overall weight is heavy, which increases the overall weight of the spring-tooth recovery and picking device. During the picking process, when the soil is relatively wet and the sand and gravel content is relatively high, it encounters greater resistance when operating on the ground, and the residual film recovery machine is burdened with a greater burden and lacks flexibility, which further causes the residual film recovery operation efficiency to become low. In view of the shortcomings of the prior art, a relatively light residual film picking roller is provided, which can improve the residual film picking work efficiency of the residual film recovery machine.

[0029] The residual film picking roller disclosed in the present invention comprises a roller body, a central transmission shaft, a shaft disc, a roller side plate, a film picking spring tooth group, a film picking crank, and a crank roller; the track disc device is used in conjunction with the film picking crank and crank roller on the roller body.

[0030] The main body of the residual film picking roller of the present invention is provided with a plurality of film collecting spring tooth groups, and a driving sprocket is connected to the central transmission shaft. The crank rollers on the plurality of film picking cranks are embedded in the annular track of the track disk device. When the ground film recycling machine is running, the driving sprocket is subjected to force to drive the picking roller to operate, the film picking crank runs in the annular track of the track disk device, the film picking spring tooth group is controlled by the film picking crank, and the track disk device controls the running track of the film picking crank.

[0031] The residual film picking roller disclosed in the present invention is provided with a track disk device, and its structure mainly includes end plates, inner rail assemblies, and outer rail assemblies. The shapes of the inner rail assemblies and the outer rail assemblies are both composed of irregular annular multi-layer plates; the ring formed by the inner rail assembly is smaller than the ring formed by the outer rail assembly, and is arranged on the inner side of the outer rail assembly. The inner rail assembly and the outer rail assembly are separated by a distance, and the space between them forms an annular track.

[0032] The structure of the inner rail assembly includes an upper inner rail plate and a middle inner rail plate. The upper inner rail plate and the middle inner rail plate have the same shape and are both irregular annular plates. The upper inner rail plate, the middle inner rail plate and the end plates are separated from each other by spacer sleeves and are fixedly connected to the end plates by through-length bolts. Similarly, the structure of the outer rail assembly includes an upper outer rail plate and a middle outer rail plate. The upper outer rail plate and the middle outer rail plate have the same shape and are both irregular annular plates. The middle outer rail plate, the upper outer rail plate and the end plates are provided with spacer sleeves and are fixedly connected to the end plates by through-length bolts.

[0033] In view of the problems of low film collection efficiency and excessive weight of the whole machine during use of the existing residual film recovery machines, the present invention proposes a track plate device with reasonable structure, economical and practical structure design. When in use, the overall design is multi-layered and the overall weight is relatively light. When combined with the residual film picking roller, the burden is relatively small during the picking process, which can effectively increase the overall flexibility of the picking roller and greatly improve the efficiency of the residual film picking operation. The provided residual film picking roller is matched with the track plate device with a lightweight structure, which reduces the resistance of the locomotive when traveling, can effectively improve the efficiency of film collection and demoulding operations, and improves the working efficiency and economical practicality of the residual film recovery and straw returning machine.

[0034] The whole machine structure of the present invention also includes a traction frame structure, which is an agricultural locomotive traction frame, mainly including a main bracket, a suspension connecting frame, and a U-shaped connecting support. One end of the U-shaped connecting support is hinged to the middle of the suspension connecting frame, so that the left and right sides of the suspension connecting frame can swing up and down with the fixing bolt as the center. The other end of the U-shaped connecting support is hinged to the main bracket, and the main frame can rotate with the hinge axis as the center.

[0035] A "п"-shaped slide is provided above the U-shaped connecting support, and a strip slide groove is provided on the "п"-shaped slide. The pulley at the front end of the sliding wall extends into the strip slide groove on the "п"-shaped slide, and the pulley can slide back and forth in the strip slide groove; the transmission support is provided with a rotating shaft inside, and the transmission support and the main frame are hinged through the rotating shaft.

[0036] When the traction locomotive drives the traction frame to turn, the suspension connection frame drives the U-shaped connection support to rotate a certain angle together, forming an angle with the main frame. The lower part of the entire transmission support is hinged with the main frame through a rotating shaft, and the transmission shaft Ⅰ16 above is connected to the transmission coupling shaft. The pulley on the slide arm can slide back and forth in the strip slide groove. When the suspension connection frame drives the U-shaped connection support to rotate together, the upper transmission support rotates, driving the pulley to slide in the strip slide groove, so that the transmission coupling shaft drives the transmission shaft Ⅰ16 to rotate, forming a transmission angle.

[0037] In this way, when the agricultural locomotive turns, the suspension connecting frame drives the U-shaped connecting support to rotate, forming a rotation angle with the main frame, the transmission support drives the sliding arm to form another rotation angle with the main frame, and the transmission coupling on the transmission support rotates with the transmission shaft Ⅰ16 to form another rotation angle, thus forming a larger transmission angle between the entire power input direction and the transmission shaft. Compared with the prior art, when the agricultural locomotive turns the same corner, the present invention ensures a larger transmission angle, which greatly reduces the influence of the locomotive turning on the transmission stability of the transmission shaft Ⅰ16.

[0038] The transmission support is provided with an anti-vibration seat at the rear, and an anti-vibration block is provided at the front end of the anti-vibration seat. The anti-vibration block is made of elastic material and extends forward to elastically contact the outer wall of the lower support. The purpose is to use the anti-vibration block to contact the lower support to form friction resistance, so that the entire transmission support can rotate more smoothly when rotating, and play a role in shock absorption.

[0039] The traction frame in the whole machine structure of the present invention has a simple structure, is economical and practical, and the design can buffer the left and right swing of the traction locomotive and the working agricultural machinery connecting frame. Especially when turning, the intermediate connection function of the U-shaped connecting support and the transmission support is used, so that when the traction locomotive turns a large turn, the transmission angle formed will not be too small, and the transmission of the transmission shaft will not be greatly affected. It solves the practical problem that the connecting traction frame on the traditional traction equipment cannot change the rear transmission angle, and when the traction locomotive turns a large turn, it affects the rear transmission. There is no longer the limitation of the transmission angle caused by the turning of the traction locomotive. The traction frame of the present invention can achieve a large transmission angle, making the transmission more stable, improving the performance of the agricultural machinery, and being more adaptable, greatly improving the operation stability of the working agricultural machinery.

[0040] Compared with the prior art, the integrated machine for recovering residual film and returning straw to the field provided by the present invention has a reasonable structure, is economical and practical, can realize the combined operation of picking up residual film, recovering and packaging, and crushing and returning straw to the field, and can be used for multiple purposes in one machine; when in use, the residual film picking roller has a smaller burden during the picking process, which can effectively increase the overall flexibility of the picking roller and greatly improve the efficiency of the residual film picking operation; a special suspension traction frame is used to solve the practical problem that the angle between the power input and the drive shaft is too small, which is not conducive to the backward transmission of the locomotive, and the steering and transmission can be flexibly connected between the traction locomotive and the operating agricultural machinery; the design of multiple gear boxes and the clutch sprocket in the transmission device can make the transmission deceleration faster, ensure the stable operation of various equipment components, and be suitable for large-scale promotion and use.
