Description

Technical Field

[0001] The utility model relates to the technical field of agricultural harvesting equipment, in particular to an inclined corn harvesting platform feeding unit. Background Art

[0002] The traditional corn harvesting method mainly relies on manual labor, which is inefficient and labor-intensive. With the development of agricultural mechanization, corn harvesting machinery has gradually become an indispensable and important tool in modern agricultural production. In the development history of corn harvesting machinery, the corn header feeding device is one of the key components. Its performance and technical level directly affect the operating efficiency and quality of the entire harvesting machinery.

[0003] At present, the feeding method used by corn plate-type ear-picking harvesters on the market is mainly horizontally arranged double-row chain teeth or single-row chain teeth feeding. The double-row chain teeth feeding process is relatively stable, but the overall structure is complex. The horizontal arrangement of the chain teeth makes the feeding row spacing large and cannot be reduced. The single-row chain teeth feeding design is relatively simple, but the disadvantage is that during the feeding process, it is easy to offset or shake due to uneven force or uneven distribution of corn ears, affecting the stability and efficiency of feeding. Therefore, we proposed a tilted corn harvester feeding unit to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art, such as the complex structure of the double-row chain teeth, the large feeding row spacing that cannot be reduced, and the single-row chain teeth being prone to deviation or shaking due to uneven force or uneven distribution of corn ears, and to propose an inclined corn header feeding unit.

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

[0006] An inclined corn cutting platform feeding unit includes two straw dividers and two cover shells. One end of each cover shell is fixedly connected to one end of the corresponding straw divider. A triangular support seat is fixedly provided inside each cover shell. A support plate is fixedly provided on the inclined surface of the two triangular support seats on the side close to each other, and there is a certain gap between the two support plates. Two slide grooves are symmetrically provided on the two support plates. A chain is provided on the side of the two support plates close to each other.

[0007] The tilt corn head feed unit also includes:

[0008] Two sets of transmission components, which are respectively arranged on two corresponding support plates and are used to drive the chain to rotate after connecting with the external transmission mechanism;

[0009] A reed plowing assembly is provided on the outside of the corresponding chain and is used for plowing the corn;

[0010] Two sets of tensioning assemblies are respectively provided at one end of two triangular support seats, and the two sets of tensioning assemblies are used to adjust the tension of the corresponding chains.

[0011] Furthermore, the transmission assembly includes a driving chain shaft, which is arranged in a slide groove at one end of the support plate and is rotatably connected to the support plate. A driving sprocket is provided in a fixed sleeve on the outer wall of the driving chain shaft, and a driven chain shaft is slidably fitted in the slide groove at one end of the support plate away from the driving chain shaft. The outer wall of the driven chain shaft is located in a fixed sleeve in the groove and is provided with a driven sprocket. The driving sprocket and the driven sprocket are both connected in a corresponding chain transmission.

[0012] Furthermore, the plowing assembly includes multiple plowing teeth I and plowing teeth II, multiple plowing teeth I are fixedly arranged on the outside of one chain, and multiple plowing teeth II are fixedly arranged on the outside of another chain, and the ends of multiple plowing teeth I and plowing teeth II that are close to each other are staggered with each other.

[0013] Furthermore, the plurality of shift teeth I and shift teeth II are all bent, and the bending angles are complementary to the corresponding inclination angles of the support plates, so that the staggered ends are in a horizontal position.

[0014] Furthermore, the tensioning assembly includes a fixed seat, which is fixedly arranged on the inner wall of the triangular support seat close to the support plate, and the fixed seat and the driven chain shaft are located at the same end. A sliding hole is opened on the fixed seat, and a screw is slidably connected to the inner wall of the sliding hole. One end of the screw is fixedly connected to the movable seat, and one end of the driven chain shaft is rotatably connected to one side of the movable seat. The screw is threadedly connected to a nut, and the screw is located between the fixed seat and the nut and is sleeved with a tensioning spring, and the two ends of the tensioning spring respectively conflict with one side of the nut and one side of the fixed seat.

[0015] Furthermore, an ear-blocking plate for blocking ears of grain is fixedly provided on one end of the two grain dividers close to the cover shell.

[0016] In this application, the unit is first assembled on the corn ear harvesting platform frame, and then the dynamic chain shaft is connected to the external transmission mechanism. The driving chain shaft drives the driving sprocket to rotate, and then drives the chain to circulate in the convex groove. At the same time, the driven chain shaft and the driven sprocket rotate with the movement of the chain to form a stable transmission system.

[0017] As the corn harvester moves forward, the corn stalks are separated and guided to the feeding port by the front-end straw divider. The pick teeth I and II contact and grab the corn stalks during the rotation process, and transport them backward along the chain path. Under the joint action of the ear picking plate and the stem pulling roller on the corn ear picking table frame, the corn ears are separated from the stalks and fall on the ear picking plate. As the chain teeth rotate, the corn ears are smoothly transported to the subsequent device. The double-row feed of the pick teeth I and II fixed on the outside improves the feeding reliability and work efficiency. In addition, the pick teeth I and II are designed with bending angles, and the bending angles are complementary to the inclination angles of the support plates, which effectively reduces the feeding row spacing.

[0018] When the chain becomes loose due to long-term use, the nut on the screw can be rotated to release the elastic force of the tensioning spring. The elastic force of the tensioning spring can be used to move the position of the moving seat, thereby changing the distance between the driven chain shaft and the driving chain shaft to adjust the chain tension.

[0019] The design of the cover and ear guard also enhances the stability of the feeding process and reduces the scattering and loss of corn ears. Beneficial effects

[0020] This tilted corn header feeding unit uses a double-row reel chain for feeding, which improves feeding reliability and work efficiency. At the same time, the reel teeth of the reel assembly are bent and have a complementary inclination angle with the support plate, effectively reducing the feeding row spacing.

[0021] The tensioning assembly is set up to adjust the chain tension according to the actual situation to prevent the chain from loosening or falling off and improve working stability;

[0022] The design of the cover and ear retaining plate also enhances the stability of the feeding process and reduces the scattering and loss of corn ears;

[0023] In this technology, the feeding device has a simple overall structure, is easy to load and unload and maintain, and realizes efficient and stable feeding of corn ears, greatly improving the operating efficiency and quality of corn harvesting machinery;

[0024] In this technology, the feeding reliability and work efficiency are improved by using a double-row plowing chain for feeding. At the same time, the plowing teeth of the plowing assembly are designed with a bending angle that is complementary to the inclination angle of the support plate, which effectively reduces the feeding row spacing. The tensioning assembly prevents the chain from loosening or falling off, thereby improving working stability. The design of the cover and the ear baffle reduces the scattering and loss of corn ears. The structure is simple and easy to load, unload and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0031] Reference Figures 1-4 A corn cutting platform feeding unit includes two straw dividers 1, two cover shells 3, a triangular support seat 4, a support plate 5, a transmission component, a straw dividing component and a tensioning component.

[0032] First, two corn dividers 1 are located on both sides of the feeding unit, which are used to preliminarily separate the corn plants to ensure that the corn ears can smoothly enter the subsequent processing area. At one end of each corn divider 1 close to the cover 3, an ear guard plate 2 is fixedly provided. The ear guard plate 2 can effectively prevent the corn ears from falling during the operation of the cutting platform, thereby improving the harvesting efficiency.

[0033] One end of the two cover shells 3 is fixedly connected to the corresponding straw divider 1 to form an overall frame structure. A triangular support seat 4 is fixedly arranged inside the cover shell 3 to enhance the stability of the overall structure. Support plates 5 are installed on the inclined surfaces of the two triangular support seats 4 that are close to each other. A certain gap is maintained between the support plates 5 to accommodate and support subsequent transmission and straw dividing components.

[0034] Two groups of transmission components are designed on the support plate 5, each group of transmission components includes a driving chain shaft 6, a driving sprocket 7, a driven chain shaft 8 and a driven sprocket 9. The driving chain shaft 6 is rotatably connected to the support plate 5 through a slide groove, and the driving sprocket 7 is fixedly sleeved on its outer wall. The driven chain shaft 8 slides in the slide groove at the other end of the support plate 5, and a driven sprocket 9 is fixedly sleeved in the groove on its outer wall. The driving sprocket 7 and the driven sprocket 9 are connected by a chain 10. When an external transmission mechanism such as a power output device of a harvester drives the driving chain shaft 6 to rotate, the chain 10 rotates accordingly, thereby driving the subsequent plowing components to work.

[0035] The plowing assembly includes a plurality of plowing teeth I 11 and plowing teeth II 12 respectively fixed on the outside of the two chains 10. These plowing teeth are staggered so that during the rotation of the chain 10, the corn plants can be effectively pushed to the center to achieve the feeding operation. In particular, in order to improve the plowing effect, the plowing teeth I 11 and the plowing teeth II 12 are both bent, and the bending angle is complementary to the inclination angle of the support plate 5, so that the staggered ends are in a horizontal position, which effectively reduces the feeding row spacing and better adapts to the growth state of the corn plants.

[0036] The present application can be used in the technical field of agricultural harvesting equipment, and can also be used in other fields applicable to the present application. Example

[0037] refer to Figure 4 , improved on the basis of Example 1: an inclined corn cutting table feeding unit, which is applied to the technical field of agricultural harvesting equipment. In order to maintain the appropriate tension of the chain 10, two sets of tensioning components are designed, each set of tensioning components includes a fixed seat 13, a screw, a movable seat 14, a tensioning spring 15 and a nut. The fixed seat 13 is installed on the inner wall of the triangular support seat 4 on one side close to the support plate 5, and is located at the same end as the driven chain shaft 8. A sliding hole is opened on the fixed seat 13, and the screw passes through the sliding hole and is fixedly connected to the movable seat 14. One end of the driven chain shaft 8 is rotatably connected to the movable seat 14. A nut is threaded on the screw, and a tensioning spring 15 is sleeved between the nut and the fixed seat 13. By rotating the nut, the compression degree of the tensioning spring 15 can be adjusted, thereby controlling the tension of the driven chain shaft 8 and the chain 10 to ensure stable operation of the transmission system.
