Description

Technical Field

[0001] This invention relates to the field of corn harvester technology, and in particular to a single-row corn harvester with automatic bagging. Background Technology

[0002] Existing single-row corn harvesters harvest corn by hand, then use control components to dump the corn into piles in the field, and finally have people manually pick up the corn and bag it to complete the entire corn harvesting process. However, picking up and bagging corn still involves a lot of labor intensity. To address this issue, an automatic bagging single-row corn harvester is proposed.

[0003] Publication number CN212413869U discloses a self-propelled single-row corn harvester, belonging to the field of agricultural machinery technology. It solves the problem of traditional corn harvesters in the prior art having difficulty frequently turning or maneuvering. This utility model is mainly used in mountainous and hilly areas. Publication number CN220173823U discloses a walk-behind single-row corn harvester. Through optimized structure, the harvester is made more compact, facilitating single-person operation on hilly terrain and greatly improving harvesting efficiency.

[0004] The aforementioned single-row corn harvesters, according to their publicly available technical solutions, are all suitable for hilly terrain. However, they do not solve the problem that corn harvesters can only pile corn on the ground and require manual picking and bagging, thus failing to achieve automatic bagging. Summary of the Invention

[0005] This invention proposes an automatic bagging single-row corn harvester to solve the problem that existing single-row corn harvesters can only drop corn onto the ground and then manually pick it up and bag it.

[0006] In a first aspect, this disclosure provides an automatic bagging single-row corn harvester, specifically comprising: a corn harvester body; a conveyor bucket mounted on the right side of the corn harvester body, a support frame assembly mounted on the rear bottom of the corn harvester body, and an mounting rod mounted on the front bottom of the corn harvester body; the support frame assembly includes a mounting plate, and a bag-supporting assembly is mounted on the front outer side of the mounting plate; a collection box is provided at the bottom front side of the conveyor bucket, and a conveyor chain is installed inside the conveyor bucket, with the discharge port of the conveyor chain located directly above the bag-supporting assembly.

[0007] In at least some embodiments, a roller is rotatably connected to the outer side of the mounting rod via a shaft, and a square sleeve is welded to the rear side of the mounting rod. A vertical connecting hole is opened inside the square sleeve. The square sleeve is fitted onto the outside of the connecting frame and is fixedly connected to the connecting frame by a bolt assembly. The mounting position of the mounting rod can be adjusted by using the connecting hole inside the connecting frame, thereby realizing the adjustment of the mounting position of the roller in the left and right directions.

[0008] In at least some embodiments, a baffle is installed on the conveyor chain inside the conveyor hopper. The baffle has a right-angle structure. The height of the collection box is higher than the height of the side panels on both sides of the conveyor hopper. A through hole is opened at the bottom of the collection box. The width of the through hole is greater than the height of the baffle. The through hole ensures that the conveyor chain and the baffle can move freely while ensuring that the corn ears do not fall out of the collection box. The corn ears are quantitatively conveyed upward by the conveyor chain and the baffle. When the conveyor chain turns downward at the top of the conveyor hopper, the corn ears fall above the support plate and are put into the bag to achieve automatic bagging and complete the corn harvest. The upright plates on both sides of the collection box ensure that the corn ears do not fall during the transmission process. The through holes at both ends of the conveyor hopper can ensure that the transmission chain and the baffle can move freely while ensuring that some debris can fall to the ground, keeping the inside of the conveyor hopper clean.

[0009] In at least some embodiments, a locking post is inserted laterally inside the mounting plate. The locking post is a regular polygonal prism structure. A limiting plate is locked onto the outer side of the mounting plate and the locking post. The tilt angle of the limiting plate is the same as the tilt angle of the bag support assembly.

[0010] In at least some embodiments, the bag support assembly consists of a first support ring and a second support ring. A transverse insertion hole is provided inside the top connecting plate of the first and second support rings, and an insertion post passes through the insertion hole. The insertion post is snapped into the mounting plate, and the insertion post and the snap-in post have the same structure. Arc-shaped strips are respectively provided at the ends of the first and second support rings, and their positions are staggered. A spring sleeve rod is provided at the end of the arc-shaped strip of the first support ring to connect to the second support ring, and a spring sleeve rod is provided at the end of the arc-shaped strip of the second support ring to connect to the first support ring. A fixing frame is provided on the top surface of the first and second support rings. The top of the fixing frame is fixedly welded to the upper edge of the connecting plate at the top of the bag support assembly. The upper half of the fixing frame is fixedly welded to the top surface of the support ring, and the lower half of the fixing frame is in a free state. The outer side is equipped with a fixing sleeve, and the inside of the fixing sleeve is connected to an arc-shaped rod by a spring. The arc-shaped rod on one side of the first support ring passes through the first support ring, and the arc-shaped rod on one side of the second support ring passes through the second support ring. The end of the arc-shaped rod is engaged in the groove on the top surface of the fixing frame. When the locking pin passes through the insertion hole inside the first and second support rings, the installation and angle adjustment of the first and second support rings are completed. After pressing the first and second support rings in the middle, the spring sleeve rod is also compressed and closed at the same time, and the diameter of the bag-supporting assembly becomes smaller. After the bag is put on the bag-supporting assembly, the first and second support rings are released. The spring sleeve rod is pushed outward by the spring to expand and reset the first and second support rings, tightening the bag opening and ensuring that the corn ears can fall into the bag automatically, thus realizing automatic bagging.

[0011] In at least some embodiments, the support frame assembly further includes a fixed bracket, connecting legs, and a support plate. The fixed bracket is fixedly connected to the front side of the bottom frame of the corn harvester body. The connecting legs are fixedly connected to the bottom surface of the fixed bracket. There are two connecting legs, which are mirror-symmetrical. The outer side of the connecting legs is provided with protruding columns. The two upright plates of the support plate are fixedly connected between the two connecting legs by bolt assemblies. The side of the support plate is provided with protruding columns. A spring is connected between the support plate and the protruding column on the same side of the connecting legs. When the bolt assembly is not particularly tight, the support plate can rotate. The spring pulls the support plate to tilt upward at a certain angle. When the bag is supported on the support frame assembly and becomes heavy with corn ears, it presses the support plate to rotate downward until the rear edge of the support plate touches the ground, causing scraping and increasing resistance. This also reminds the operator that the bag is full of corn ears and needs to be replaced.

[0012] In at least some embodiments, a shovel frame is provided on the front side of the main body of the corn harvester, a guide rod is fixedly provided on the front side of the main body of the corn harvester, a toothed gear transmission box is installed on the left front end of the main body of the corn harvester, toothed gears are installed inside the toothed gear transmission box, and a tasseling roller is installed at the lower rear of the toothed gear transmission box. The drive assembly of the tasseling roller and the toothed gear transmission box is connected to the drive assembly on the main body of the corn harvester through a transmission mechanism. The transmission mechanism adopts one or both of the following: a transmission belt or a transmission gear set. The tasseling roller or toothed gears are driven by the drive assembly. There are two tasseling rollers, and two inclined plates are installed above the spacing between them. The bottom of the inclined plate is... The corn harvester body is installed on the guide plate, and the edge of the guide plate is fixedly connected to the bottom edge of the collection box. The front bottom of the corn harvester body is fastened to the connecting frame by bolt assembly. The connecting frame has vertical connecting holes inside. The upper rear of the corn harvester body is equipped with a handrail. The corn stalks to be harvested are gathered into the inner side of the gathering frame using the gathering frame. When the corn harvester body moves forward, the teeth cut the corn stalks and the ear-pulling roller stirs the corn stalks downward. At the same time, the corn ears are left between the two slope plates. The corn ears are guided by the slope plates and the guide plate and roll into the collection box, completing the first step of corn harvesting.

[0013] This invention provides an automatic bagging single-row corn harvester, which has the following beneficial effects: In use, the corn ears are conveyed upwards in a quantitative manner through a conveyor chain and baffles. When they reach the top of the conveyor hopper, the conveyor chain turns downwards and the corn ears fall onto the support plate and are put into bags, thus achieving automatic bagging and completing the corn harvest. There is no need for manual picking up of corn, which improves the efficiency of corn harvesting.

[0014] Furthermore, when the bag is placed inside the bag-supporting assembly and the bag opening is spread outwards, pressing the support ring causes the arc-shaped rod to move radially. The arc-shaped rod slides into the fixed sleeve while compressing the spring, increasing the distance between the end of the arc-shaped rod and the top surface of the fixed frame. After the edge of the bag is placed below the end of the arc-shaped rod, the support ring is released and pushed back to its original position by the spring, simultaneously causing the arc-shaped rod to return to its original position. The end of the arc-shaped rod is inserted into the groove on the top surface of the fixed frame, engaging the edge of the bag and fixing the bag opening. When the bag is placed outside the bag-supporting assembly and the bag opening is folded inwards, the same action described above can be used to hook the bag opening with the arc-shaped rod, thus fixing the bag opening as well. Both bag-attaching methods can achieve a good bag-supporting effect.

[0015] In addition, the mounting position of the mounting rod can be adjusted by using the connecting holes inside the connecting frame, so as to adjust the mounting position of the rollers in the left and right directions. This allows the roller spacing to be suitable for cornfields with different row spacing, ensuring that the main body of the corn harvester can be used for single-row harvesting in more cornfields.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to the appendix. Figure 1 To be continued Figure 5 : This invention proposes an automatic bagging single-row corn harvester, comprising: a corn harvester body 1; a conveyor bucket 2 installed on the right side of the corn harvester body 1, a support frame assembly 3 installed at the rear bottom of the corn harvester body 1, and an installation rod 4 installed at the bottom front of the corn harvester body 1; the support frame assembly 3 includes an installation plate 34, and a bag-supporting assembly 5 is installed on the outer front side of the installation plate 34; a collection box 201 is provided at the front bottom of the conveyor bucket 2, and a conveyor chain is installed inside the conveyor bucket 2, with the discharge port of the conveyor chain located directly above the bag-supporting assembly 5.

[0022] As attached Figure 2 As shown in the description, a roller is rotatably connected to the outer side of the mounting rod 4 via a shaft. A square sleeve is welded to the rear side of the mounting rod 4. A vertical connecting hole is opened inside the square sleeve. The square sleeve is fitted onto the outside of the connecting frame 104 and is fixedly connected to the connecting frame 104 by a bolt assembly. The mounting position of the mounting rod 4 can be adjusted by using the connecting hole inside the connecting frame 104, so that the mounting position of the roller can be adjusted in the left and right directions, making the roller spacing suitable for cornfields with different ridge spacing, and ensuring that the main body of the corn harvester 1 is suitable for single-row harvesting in more cornfields.

[0023] As attached Figure 5As shown in the description, the top surfaces of the first support ring 51 and the second support ring 52 are respectively provided with fixing frames 503. The top of the fixing frame 503 is fixedly welded to the upper edge of the connecting plate at the top of the bag support assembly 5. The upper half of the fixing frame 503 is fixedly welded to the top surface of the support ring, and the lower half of the fixing frame 503 is in a free state. The outer side of the fixing frame 503 is provided with a fixing sleeve 5031. The inside of the fixing sleeve 5031 is connected to an arc-shaped rod 5032 by a spring. The arc-shaped rod 5032 on one side of the first support ring 51 passes through the first support ring 51, and the arc-shaped rod 5032 on one side of the second support ring 52 passes through the second support ring 52. The end of the arc-shaped rod 5032 is engaged in the groove on the top surface of the fixing frame 503. When the bag is placed inside the bag support assembly 5 and the bag opening is opened outward, pressing the first support ring 51 or the second support ring 52 will... The curved rod 5032 moves radially and slides into the fixed sleeve 5031 while compressing the spring. The distance between the end of the curved rod 5032 and the top surface of the fixed frame 503 increases. After the edge of the bag is placed below the end of the curved rod 5032, the first support ring 51 or the second support ring 52 is released. The spring pushes the first support ring 51 or the second support ring 52 to reset, and at the same time, the curved rod 5032 is reset. The end of the curved rod 5032 is inserted into the groove on the top surface of the fixed frame 503 to bite the edge of the bag and fix the bag opening. When the bag is put on the outside of the bag support assembly 5 and the bag opening is folded inward, the same action is used to hook the bag opening through the curved rod 5032, which can also fix the bag opening. Both bag putting methods can achieve a good bag supporting effect.

[0024] In the embodiments disclosed herein, as shown in the appendix Figure 1 and attached Figure 2As shown in the contents, a corn harvester body 1 has a winch frame 101 on its front side, a guide rod 102 fixedly installed on the front side of the corn harvester body 1, a tooth transmission box 103 installed on the left front end of the corn harvester body 1, toothed gears installed inside the tooth transmission box 103, and a tasseling roller installed at the lower rear of the tooth transmission box 103. The drive assembly of the tasseling roller and the tooth transmission box 103 is connected to the drive assembly on the corn harvester body 1 through a transmission mechanism. The transmission mechanism uses one or both of the following: a transmission belt or a transmission gear set. The tasseling roller or the toothed gear is driven by the drive assembly. There are two tasseling rollers with two ramps installed above the gap between them, and the bottom of the ramp is installed on... A guide plate is fixedly connected to the bottom edge of the collection box 201. A connecting frame 104 is fastened to the front bottom of the corn harvester body 1 by bolt assembly. The connecting frame 104 has vertical connecting holes inside. A handrail 105 is installed on the upper rear of the corn harvester body 1. The corn stalks to be harvested are gathered into the inner side of the gathering frame 101 using the gathering frame 101. When the corn harvester body 1 moves forward, the teeth cut the corn stalks and the ear-pulling roller stirs the corn stalks downward. At the same time, the corn ears are left between the two slope plates. The corn ears are guided by the slope plates and the guide plate and roll into the collection box 201, completing the first step of corn harvesting.

[0025] As attached Figure 3 and attached Figure 4 As shown in the contents, the support frame assembly 3 also includes a fixed bracket 31, a connecting leg 32, and a support plate 33. The fixed bracket 31 is fixedly connected to the front side of the bottom frame of the main body 1 of the corn harvester. The connecting leg 32 is fixedly connected to the bottom surface of the fixed bracket 31. There are two connecting legs 32, which are mirror-symmetrical. The outer side of the connecting leg 32 is provided with a protruding post. The two upright plates of the support plate 33 are fixedly connected between the two connecting legs 32 by bolt assemblies. The side of the support plate 33 is provided with a protruding post. A spring is connected between the support plate 33 and the protruding post on the same side of the connecting leg 32. When the bolt assembly is not particularly tight, the support plate 33 can rotate. The spring pulls the support plate 33 to tilt upward at a certain angle. When the bag is supported on the support frame assembly 3 and becomes heavy with corn ears, it presses the support plate 33 to rotate downward until the rear edge of the support plate 33 touches the ground, causing a scraping and increasing resistance. This also reminds the operator that the bag is full of corn ears and needs to be replaced.

[0026] As attached Figure 4As shown in the contents, a locking post 3401 is horizontally inserted into the interior of the mounting plate 34. The locking post 3401 is a regular polygonal prism structure. A limiting plate 3402 is locked onto the outer side of the mounting plate 34 and the locking post 3401. The tilt angle of the limiting plate 3402 is the same as the tilt angle of the bag support assembly 5. The locking post 3401 can facilitate the connection between the mounting plate 34 and the bag support assembly 5, enabling quick assembly and disassembly. At the same time, the locking post 3401 can provide angle adjustment, while the limiting plate 3402 increases the supporting force on the bag support assembly 5, ensuring that the supporting force of the bag support assembly 5 is large enough, and maintaining the stability of the angle while the corn is harvested and vibrates.

[0027] As attached Figure 4 As shown in the content, the bag support assembly 5 consists of a first support ring 51 and a second support ring 52. The top connecting plate of the first support ring 51 and the second support ring 52 has a transverse insertion hole, through which an insertion post 501 passes. The insertion post 501 is snapped into the mounting plate 34, and the insertion post 501 has the same structure as the snap post 3401. The ends of the first support ring 51 and the second support ring 52 are respectively provided with arc-shaped strips 502, which are staggered. A spring sleeve rod is provided at the end of the arc-shaped strip 502 of the first support ring 51, connecting it to the second support ring 52. A spring sleeve rod is also provided at the end of the arc-shaped strip 502 of the second support ring 52. Upon receiving the first support ring 51, after the locking pin 3401 passes through the insertion holes inside the first and second support rings 51 and 52, the installation and angle adjustment of the first and second support rings 51 and 52 are completed. Pressing the first and second support rings 51 and 52 towards the center simultaneously compresses the spring sleeve rod, causing the diameter of the bag-supporting assembly 5 to decrease. After the bag is placed on the bag-supporting assembly 5, the first and second support rings 51 and 52 are released. The spring sleeve rod, under the action of the spring, pushes the first and second support rings 51 and 52 outward to reposition themselves, tightening the bag opening and ensuring that the corn ears can automatically fall into the bag, thus achieving automatic bagging. Figure 1 and Figure 3 As shown in the contents, a baffle 202 is installed on the conveyor chain inside the conveyor bucket 2. The baffle 202 has a right-angle structure. The height of the collection box 201 is higher than the height of the side panels on both sides of the conveyor bucket 2. A through hole is opened at the bottom of the collection box 201. The width of the through hole is greater than the height of the baffle 202. The through hole ensures that the conveyor chain and the baffle 202 can move freely while ensuring that the corn ears will not fall outside the collection box 201. The corn ears are quantitatively conveyed upward through the conveyor chain and the baffle 202. When the conveyor chain turns downward at the top of the conveyor bucket 2, the corn ears fall above the support plate 33 and are put into the bag to realize automatic bagging and complete the corn harvest.

[0028] Example 2, based on Example 1, as shown in the appendix. Figure 6As shown, the bag support assembly 5 can be replaced with an integrally molded arc-shaped plate. The end of the arc-shaped plate is snapped onto the mounting plate 34 via a locking post 3401. By compressing the middle of the arc-shaped plate inward, the diameter of the opening can be changed. After the bag opening is put onto the outside of the arc-shaped plate, the arc-shaped plate is released. The elasticity of the arc-shaped plate is used to open the bag opening. Then, the edge of the bag opening is pressed between the bag and the arc-shaped plate to ensure the bag opening is fixed. This method can reduce the production cost of the bag support assembly 5 and is conducive to its implementation and promotion.

[0029] The working principle of this embodiment is as follows: When the bag is placed inside the bag support assembly 5 and the bag opening is opened outward, pressing the first support ring 51 or the second support ring 52 will drive the arc rod 5032 to move radially. The arc rod 5032 slides into the fixed sleeve 5031 and compresses the spring at the same time. The distance between the end of the arc rod 5032 and the top surface of the fixed frame 503 increases. After the edge of the bag is placed below the end of the arc rod 5032, the first support ring 51 or the second support ring 52 is released. The first support ring 51 or the second support ring 52 is pushed back to its original position by the spring. At the same time, the arc rod 5032 is reset. The end of the arc rod 5032 is inserted into the groove on the top surface of the fixed frame 503 to bite the edge of the bag and fix the bag opening. After holding the handle 105, operate the main body 1 of the corn harvester to move forward. Use the gathering frame 101 to gather the corn stalks to be harvested to the inside of the gathering frame 101. When the main body 1 of the corn harvester moves forward, the teeth cut the corn stalks and the ear-pulling roller stirs the corn stalks downward. At the same time, the corn ears are left between the two slope plates. The corn ears are guided by the slope plates and the guide plate and roll into the collection box 201. The corn ears are conveyed upwards in a measured amount via a conveyor chain and baffle 202. When they reach the top of the conveyor hopper 2, the conveyor chain loops downwards, and the corn ears fall into the bag, achieving automatic bagging. After the bag is filled with corn ears and becomes heavier, it presses the support plate 33 to rotate downwards until the rear edge of the support plate 33 touches the ground. This scraping increases resistance and also reminds the operator that the bag is full of corn ears and needs to be replaced.
