Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to an automatic regurgitation header. Background Technology

[0002] A corn harvester is an agricultural implement used to harvest corn stalks when corn is mature or near maturity, according to agronomic requirements. With the development of technology, existing corn harvesters can simultaneously collect and crush corn stalks and debris during the corn harvesting process. However, during the operation of the harvester, the silage mechanism and feeding mechanism may jam due to the surrounding environment or improper human operation. This will increase the load on the equipment and may even cause the entire equipment to malfunction. Therefore, timely maintenance and cleaning of the equipment are required, which greatly reduces the convenience and efficiency of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide an automatic back-out cutting table to address the shortcomings of existing technologies.

[0004] An automatic backfeeding header includes a silage mechanism, a feeding mechanism, a power source, and a power transmission mechanism disposed at the header. The power transmission mechanism includes a first rotating shaft, a second rotating shaft, a third rotating shaft, a fourth rotating shaft, and a backfeeding drive device. A first gear is fixedly disposed on the first rotating shaft, a second gear and a third gear are fixedly disposed on the second rotating shaft, a fourth gear is fixedly disposed on the third rotating shaft, and a fifth gear is disposed on the fourth rotating shaft. The power source is driven to the first rotating shaft. The first gear and the second gear mesh with each other, as do the second gear and the fourth gear. The third rotating shaft is driven to the silage mechanism. The backfeeding drive device is driven to the fourth rotating shaft. The fifth gear is slidably disposed on the fourth rotating shaft and is driven to the fourth rotating shaft. An adjustment component is disposed on the fifth gear, which controls the meshing of the fifth gear with the third gear. The power source is driven to the third rotating shaft, which is driven to the silage mechanism. The first rotating shaft is driven to the feeding mechanism.

[0005] Furthermore, the adjustment assembly includes a sliding rod and a sliding member. The sliding rod is arranged parallel to the fourth rotating shaft, and the sliding member is fixedly installed on the sliding rod. The fifth gear is provided with an adjustment groove, and the sliding member is slidably embedded in the adjustment groove of the fifth gear.

[0006] Furthermore, an adjustment handle is vertically provided on the sliding rod.

[0007] Furthermore, it also includes an adjusting cover plate, which is provided with a limiting groove, and the adjusting handle passes through the limiting groove in a U-shape.

[0008] Furthermore, a sliding spring is fitted onto the sliding rod, and the sliding spring pushes the sliding rod toward the adjusting handle.

[0009] Furthermore, the anti-spitting drive device is a hydraulic motor.

[0010] Furthermore, the transmission ratio between the fifth gear and the third gear is 1:1.5-1:3.

[0011] Furthermore, the transmission ratio between the fifth gear and the third gear is 1:1.5, 1:2, 1:2.5, or 1:3.

[0012] Furthermore, the transmission ratio of the first gear and the second gear is 1:1.5-1:3.

[0013] Furthermore, the transmission ratio of the first gear and the second gear is 1:1.5, 1:2, 1:2.5 or 1:3.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] Firstly, this solution incorporates a power transmission mechanism. When the equipment is running normally, the adjusting component causes the fifth gear to separate from the third gear. At this time, the power source generates conveying power, which enters the power transmission mechanism to drive the silage mechanism. When the equipment jams, the power source is first disconnected from the power output of the third shaft. Then, the adjusting component moves the fifth gear to the position of the third gear, causing the fifth gear to mesh with the third gear. This activates the reverse drive device, which drives the fifth gear to rotate. The fifth gear then drives the third gear to reverse, thus achieving reverse drive of the silage mechanism. Simultaneously, the rotation of the third gear drives the second shaft, which in turn drives the first gear. The rotation of the first gear drives the first shaft, which in turn drives the feeding mechanism to reverse, thereby achieving material reversal and improving the ease of use of the equipment.

[0016] Secondly, the adjustment component in this solution includes a sliding rod and a sliding element. Through the cooperation of the sliding element and the fifth gear, the fifth gear can be driven to move laterally on the fourth rotating shaft, thereby realizing the effect of the adjustment component controlling the connection and disconnection of the fifth gear and the third gear.

[0017] Thirdly, this solution includes an adjustment cover plate with a limiting groove. The limiting groove is U-shaped, through which the adjustment handle passes. The limiting groove limits the sliding direction of the adjustment handle within it. The U-shaped structure allows the adjustment handle to be in two positions, preventing incorrect reset. When the adjustment handle is in the limiting groove near the third gear, the fifth gear meshes with the third gear. When the adjustment handle is in the limiting groove away from the third gear, the fifth gear disengages from the third gear. Attached Figure Description

[0025] Combined with appendix Figure 1-6As shown, an automatic reverse-feeding header includes a silage mechanism 1, a feeding mechanism 2, a power source, and a power transmission mechanism 3. Power is transmitted from the power source to the power transmission mechanism 3. The silage mechanism 1 collects corn stalks and feeds them to the feeding mechanism 2. The feeding mechanism 2 then transports the corn stalks and scraps to a chopping mechanism for further processing. When the equipment is running normally, the power source generates power and transmits it to the power transmission mechanism 3, which then transmits the power to the silage mechanism 1 to keep it running. When the equipment jams, the power source is disconnected, and the power transmission mechanism 3 is activated to reverse the flow of the silage mechanism 1 and the feeding mechanism 2. The material in the feeding mechanism 2 is then reversed and transported back to the silage mechanism 1, facilitating cleaning and maintenance of the equipment.

[0026] Preferably, the power transmission mechanism 3 includes a first rotating shaft 31, a second rotating shaft 32, a third rotating shaft 33, a fourth rotating shaft 34, and a reverse drive device 35. A first gear 311 is fixedly mounted on the first rotating shaft 31, a second gear 321 and a third gear 322 are fixedly mounted on the second rotating shaft 32, a fourth gear 331 is fixedly mounted on the third rotating shaft 33, and a fifth gear 341 is mounted on the fourth rotating shaft 34. The power source is driven to the first rotating shaft 31, and the first gear 311 and the second gear 321 are in contact with each other. The second gear 321 and the fourth gear 331 mesh with each other. The third rotating shaft 33 is driven to the silage mechanism 1. The anti-spitting drive device 35 is driven to the fourth rotating shaft 34. The fifth gear 341 is slidably disposed on the fourth rotating shaft 34. An adjustment component is provided on the fifth gear 341. The adjustment component controls the fifth gear 341 to mesh with the third gear 322. The power source is driven to the third rotating shaft 33. The third rotating shaft 33 is driven to the silage mechanism 1. The first rotating shaft 31 is driven to the feeding mechanism 2.

[0027] like Figure 5 As shown, when the equipment is running normally, the adjustment component drives the fifth gear 341 to separate from the third gear 322. At this time, the power source generates transmission power to enter the power transmission mechanism 3 to drive the silage mechanism 1 to run.

[0028] like Figure 6As shown, when the equipment is stuck, the power source and the power output of the third rotating shaft 33 are first disconnected. Then, the fifth gear 341 is moved to the third gear 322 by the adjusting component, so that the fifth gear 341 and the third gear 322 mesh. The reverse discharge drive device 35 is started. The reverse discharge drive device 35 drives the fifth gear 341 to rotate. The fifth gear 341 drives the third gear 322 to reverse, thereby realizing the reverse drive of the silage mechanism 1. At the same time, the rotation of the third gear 322 drives the second rotating shaft 32. The rotation of the second rotating shaft 32 drives the first gear 311. The rotation of the first gear 311 drives the first rotating shaft 31. The first rotating shaft 31 drives the feeding mechanism 2 to reverse, thereby realizing the material discharge operation.

[0029] Preferably, the adjusting assembly includes a sliding rod 342 and a sliding member 343. The sliding rod 342 is arranged parallel to the fourth rotating shaft 34. The sliding member 343 is fixedly installed on the sliding rod 342. The fifth gear 341 is provided with an adjusting groove. The sliding member 343 is slidably embedded in the adjusting groove of the fifth gear 341. When the operator slides the sliding rod 342 in the axial direction, it drives the sliding member 343 to move laterally. Through the cooperation between the sliding member 343 and the fifth gear 341, the fifth gear 341 can be driven to move laterally on the fourth rotating shaft 34. This enables the adjusting assembly to control the connection and disconnection of the fifth gear 341 and the third gear 322.

[0030] Furthermore, to improve the ease of adjustment of the sliding rod 342, an adjustment handle 344 is vertically provided on the sliding rod 342.

[0031] Furthermore, an adjusting cover plate is also included, which is provided with a limiting groove 345. The limiting groove 345 is U-shaped, through which the adjusting handle 344 passes. The limiting groove 345 can limit the sliding direction of the adjusting handle 344 in the limiting groove 345. At the same time, the U-shaped structure can allow the adjusting handle 344 to be in two positions, preventing the adjusting handle 344 from being incorrectly reset. When the adjusting handle 344 is in the limiting groove 345 on the side closer to the third gear 322, the fifth gear 341 meshes with the third gear 322. When the adjusting handle 344 is in the limiting groove 345 on the side away from the third gear 322, the fifth gear 341 disengages from the third gear 322.

[0032] Preferably, a sliding spring 346 is sleeved on the sliding rod 342. The sliding spring 346 pushes the sliding rod 342 toward the adjusting handle 344, thereby ensuring the sliding stability of the sliding rod 342 and preventing the adjustment of the sliding rod 342 from getting stuck.

[0033] Alternatively, the backflow drive device 35 in this solution can be a hydraulic motor, an electric motor, or a pneumatic motor, etc. Considering the application field of this application and the large drive load required by the equipment, it is preferred to set it as a hydraulic motor.

[0034] Preferably, the transmission ratio between the fifth gear 341 and the third gear 322 is 1:1.5-1:3, and the transmission ratio between the fifth gear 341 and the third gear 322 is 1:1.5, 1:2, 1:2.5 or 1:3, wherein 1:2 is preferred.

[0035] Preferably, the transmission ratio of the first gear 311 and the second gear 321 is 1:1.5-1:3, and the transmission ratio of the first gear 311 and the second gear 321 is 1:1.5, 1:2, 1:2.5 or 1:3, wherein 1:2 is preferred.

[0036] Alternatively, in this scheme, the reverse discharge drive device 35 is used to drive the silage mechanism 1 and the feeding mechanism 2 to discharge. In addition, the reverse discharge drive device 35 in this scheme can also be installed on the first rotating shaft 31, the second rotating shaft 32, the third rotating shaft 33 or the fourth rotating shaft 34 according to the actual needs of the equipment. The reverse discharge drive device 35 drives any one of the first rotating shaft 31, the second rotating shaft 32, the third rotating shaft 33 or the fourth rotating shaft 34 in the reverse direction, thereby driving the silage mechanism 1 and the feeding mechanism 2 to run in the opposite direction to achieve reverse discharge.
