Abstract
Description
Technical Field
[0001] The utility model belongs to the field of agricultural machinery, and particularly relates to a dividing header with a vibration recovery function. Background Art
[0002] The core function of the dividing header of a harvester is to guide and separate crops so that they can smoothly enter the ear picking unit of the harvester. The dividing header is located at the front end of the ear picking unit of the harvester. By adjusting its angle and position, it can effectively guide and separate lodged crops, prevent the dividing header from being damaged, and ensure that the crops can be smoothly harvested.
[0003] Traditional dividing headers are usually metal shields welded by iron plates and are fixedly installed on the cutting table between two adjacent ear picking unit brackets through bolts. Such dividing headers only play a simple role of dividing crops and are suitable for harvesting crops such as corn. However, for crops such as sesame whose grains are prone to falling, since the traditional dividing header does not have a recovery function, the fallen grains cannot be recovered, resulting in serious grain loss during the harvesting process and causing relatively large economic losses. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a dividing header with a vibration recovery function that can achieve grain recovery and reduce harvesting losses.
[0005] To solve the above problems, the utility model adopts the following technical solutions:
[0006] A dividing header with a vibration recovery function includes a base. A front shield is fixed at the front end of the base. The feature is that an upper tray is hinged to the rear end of the base through a pin shaft. Vertical edges are provided on both sides and the front edge of the upper tray, and the upper tray lies on the base in the initial state for receiving the crop grains that fall during the harvesting process.
[0007] A driving mechanism is provided near the front end on the base. The driving mechanism abuts against the bottom surface of the upper tray through a cam for driving the upper tray to swing reciprocally around the pin shaft.
[0008] A further improvement of the technical solution of the utility model lies in that a tension spring is provided between the front end of the upper tray and the base, and the upper tray is tightly attached to the outer edge of the cam under the action of the tension spring.
[0009] A further improvement of the technical solution of the utility model lies in that the inner bottom surface of the upper tray is in the shape of a slide to facilitate the grains to slide into the rear auger.
[0010] A further improvement of the technical solution of the utility model lies in that a shock-absorbing plate is provided at the bottom of the upper tray corresponding to the cam. The shock-absorbing plate is made of nylon material to avoid direct contact and abrasion between the cam and the upper tray.
[0011] A further improvement of the technical solution of the present utility model lies in that a reinforcing plate is fixed to the bottom surface of the front part of the upper tray, and the shock-absorbing plate is fixed to the bottom surface of the reinforcing plate to increase the strength of the upper tray.
[0012] A further improvement of the technical solution of the present utility model lies in that the driving mechanism includes a reduction motor fixed to the base through a motor seat, and the cam is fixed to the output end of the reduction motor.
[0013] A further improvement of the technical solution of the present utility model lies in that side guard plates are symmetrically fixed to both sides of the bottom surface of the front part of the upper tray, and the side guard plates surround the outer sides of the vertical edges provided on both sides of the front part of the base to prevent crop seeds from falling between the upper tray and the base.
[0014] A further improvement of the technical solution of the present utility model lies in that the base is a welded part formed by welding a front bottom plate and a rear bottom plate for easy processing.
[0015] The beneficial effects of the present utility model are as follows:
[0016] 1. Since the upper tray is hinged to the rear end of the base through a pin shaft, there are vertical edges at both sides and the front edge of the upper tray, and the upper tray lies on the base in the initial state, the upper tray can be used as a rear shield and can receive the crop seeds that fall during the harvesting process, especially for crops such as sesame whose seeds are easy to fall.
[0017] 2. By the driving mechanism provided on the base near the front end, the cam abuts against the bottom surface of the upper tray, and the upper tray can be driven to swing reciprocally with the pin shaft as the axis; through the regular reciprocating swing of the upper tray, the seeds in the recovery tank can be guided into the rear auger and recovered into the granary, thus realizing the return of seeds to the granary; reducing the harvesting loss and improving the economic benefit.

Detailed implementation mode
[0024] As Figures 1 to 5 shown, a threshing divider with a vibration recovery function according to the present utility model includes a base 4, and the base 4 is a welded part formed by welding a front bottom plate 401 and a rear bottom plate 402, which is convenient for processing. A conical front guard 2 is fixedly welded to the front end of the front bottom plate 401 of the base 4, and a front support plate 1 is welded to the front end of the front guard 2;
[0025] An upper tray 6 is hinged to the rear end of the rear bottom plate 402 of the base 4 through a pin shaft 5. Upturned vertical edges 601 are provided on both sides and the front edge of the upper tray 6, and the upper tray 6 falls on the base 4 in the initial state, and is used for receiving the crop grains dropped during the harvesting process.
[0026] A driving mechanism is provided near the front end of the base 4. The driving mechanism abuts against the bottom surface of the upper tray 6 through a cam 10, and is used for driving the upper tray 6 to swing reciprocally around the pin shaft. Preferably, the driving mechanism includes a reduction motor 8 fixed to the front bottom plate 401 through a motor base 9, and the cam 10 is fixed to the output end of the reduction motor 8.
[0027] A tension spring 14 is provided between the front end of the upper tray 6 and the base 4. The upper tray 6 is closely attached to the outer edge of the cam 10 under the action of the tension spring 14. A spring seat plate 7 is fixed to the front end of the motor base 9. A plurality of hanging holes are evenly distributed on the spring seat plate 7. A spring hook 13 is fixed to the bottom surface of the front end of the upper tray 6. The tension spring 14 is hung between the spring hook 13 and one of the hanging holes, so as to adjust the installation angle of the tension spring 14.
[0028] The inner bottom surface of the upper tray 6 is in the shape of a slide, so as to facilitate the grains to slide into the rear auger. A shock-absorbing plate 12 is provided at the bottom of the upper tray 6 corresponding to the cam 10, and the shock-absorbing plate 12 is made of nylon material to prevent direct contact between the cam 10 and the upper tray 6 from causing wear.
[0029] A reinforcement plate 11 is fixed to the bottom surface of the front part of the upper tray 6 by rivets. Both sides of the reinforcement plate 11 are folded into a V-shaped groove shape, and the shock-absorbing plate 12 is fixed to the middle of the bottom surface of the reinforcement plate, so as to increase the strength of the upper tray 6.
[0030] Side guard plates 3 are symmetrically welded to both sides of the bottom surface of the front part of the upper tray 6. The side guard plates 3 surround the outer sides of the vertical edges provided on both sides of the front part of the base 4, so as to prevent the crop grains from falling between the upper tray 6 and the base 4.
[0031] During use, the row divider is mounted on the cutter bar of the harvester between two adjacent ear-picking unit brackets through the base 4 using bolts, and the front bottom surface of the front guard 2 is fixedly supported between two adjacent ear-picking unit brackets through the front bracket.
[0032] During operation, crops such as sesame are introduced into each ear-picking unit on the cutter bar of the harvester through the front guard 2 and moved backward by the reel chain. The crop grains that fall during the movement fall into the upper tray 6. At the same time, after the reduction motor 8 is started, it drives the cam 10 to rotate, and with the cooperation of the tension spring 14, the upper tray 6 can be driven to swing reciprocally around the pin shaft. Through the regular swing of the upper tray 6, the grains in the recovery tank can be introduced into the rear auger and recovered into the granary, thus realizing the storage of grains in the granary, reducing the harvesting loss, and improving the economic benefits.
