Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a feeding component for an automatic harvester. Background Art

[0002] A harvester is an integrated machine for harvesting crops. It can complete harvesting and threshing at one time, and concentrate the grains in a storage bin, and then transport them to a transport vehicle via a conveyor belt. An automatic harvester completes the harvesting, threshing, and transportation of crops in one operation, saving farmers' labor and shortening the labor cycle.

[0003] The key component of the feeding structure on an automatic harvester is the auger, which is usually composed of a shaft, a shell, and blades or teeth on the shell. When the harvester moves forward, the auger rotates and rolls in the crops, which can separate the crops from the land, making it easier to harvest the separated crops. Whether the auger can rotate smoothly is related to whether the first step of harvesting can be carried out smoothly.

[0004] Shafts are provided at both ends of the auger, and the shafts are usually in direct contact with the sleeves and maintain a freely rotatable relationship with the sleeves; the shafts are then driven to rotate by a motor, thereby driving the auger to rotate; the shafts and sleeves of the auger are in complete surface-to-surface contact between entities, and during long-term use, rust may appear between the shafts and sleeves, causing the relative rotation between the two to become stuck, thereby affecting the rotation of the auger; in addition, the contact structure design of the contact surface between the shafts and the sleeves is concealed, making it difficult to effectively add lubricating oil to the contact surface between the two, and even more difficult to supply lubricating oil in real time during the operation of the machine, so that the contact surface between the shafts and the sleeves is always lubricated. Utility Model Content

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] Example 1

[0049] A feeding assembly for an automatic harvester, comprising: an auger 1, an auger driving assembly 2, a side plate 3, a top plate 4, and a back plate 5;

[0050] like Figure 1 As shown, side plates 3 are symmetrically arranged on both sides of the feeding assembly, a top plate 4 is arranged above the side plates 3, and both sides of the top plate 4 are fixedly connected to the side plates 3;

[0051] The side panels 3 and the top panel 4 constitute the external frame main structure of the feeding assembly; within the frame, an auger 1 is arranged between the two side panels 3; an auger shaft 102 is arranged at the center position of the two end surfaces of the auger 1, and an auger drive assembly 2 is arranged on the side panels 3, and the auger drive assembly 2 is connected to the auger shaft 102. Under the driving action of the auger drive assembly 2, the auger 1 can rotate; usually, only one set of auger drive assemblies 2 needs to be arranged on a single side of the side panel 3 to achieve the driving effect, but in actual application, auger drive assemblies 2 can also be arranged on both sides of the side panels 3 according to the situation, and the two sets of auger drive assemblies 2 work together to drive the auger 1 to rotate;

[0052] like Figure 2 As shown, in this embodiment, the auger drive assembly 2 includes: a shaft sleeve 201 and a motor 206;

[0053] Opening structures are provided on both the left and right sides of the shaft sleeve 201; the left side of the shaft sleeve 201 is provided on the side plate 3; the motor 206 is provided on the rear side of the shaft sleeve 201;

[0054] A shaft disc 202 is arranged inside the shaft sleeve 201. The center of the shaft disc 202 is a hollow structure. A plurality of spherical grooves are provided at equal intervals on the side wall of the hollow structure. Rolling balls 203 are movably arranged in the spherical grooves. The rolling balls 203 are movably embedded in the spherical grooves and cannot be separated from the spherical grooves.

[0055] One end of the auger shaft 102 is arranged on the end surface of the auger 1, and the other end passes through the side plate 3, extends into the shaft sleeve 201, and passes through the shaft disc 202; the surface of the auger shaft 102 located in the shaft disc 202 contacts the rolling ball 203; when the auger shaft 102 rotates, the rolling ball 203 can roll freely in the spherical groove;

[0056] One end of the auger shaft 102 extending into the shaft sleeve 201 is connected to the motor rotor 207. The motor 206 drives the motor rotor 207 to rotate, and the motor rotor 207 drives the auger shaft 102 to rotate. The auger shaft 102 can drive the auger 1 to rotate.

[0057] The traditional surface-to-surface contact between the auger shaft 102 and the rotating sleeve is improved to the contact between the surface of the auger shaft 102 and the ball 203 in this embodiment. The contact between the ball 203 and the surface of the auger shaft 102 is equivalent to the contact between point and surface. By reducing the contact area with the surface of the auger shaft 102, the friction of the auger shaft 102 during rotation can be reduced.

[0058] If the contact surface between the auger shaft 102 and the ball 203, and the contact surface between the ball 203 and the spherical groove are not lubricated in time during long-term use, the auger shaft 102 may become stuck during rotation due to rust; in this case, lubricating oil needs to be added in time to lubricate the contact surfaces; however, since the contact surface between the auger shaft 102 and the ball 203 is hidden in the shaft sleeve 201, the shaft sleeve 201 needs to be disassembled if lubricating oil is needed;

[0059] As a preferred embodiment, Figure 2 As shown, a lubricating oil supply structure is provided on the shaft sleeve 201, and the lubricating oil supply structure is communicated with the spherical groove. The lubricating oil supply structure can continuously provide lubricating oil to the spherical groove, so that the contact surface between the ball 203 and the spherical groove is fully lubricated. In addition, since the lubricating oil can also adhere to the surface of the ball 203, the contact surface between the ball 203 and the auger shaft 102 can also be fully lubricated.

[0060] The lubricating oil supply structure includes: a lubricating oil bottle 205 and a lubricating oil filling channel 204;

[0061] A lubricating oil filling channel 204 is opened inside the shaft disc 202, and a plurality of branch channels are arranged at the end of the lubricating oil filling channel 204, and each branch channel is communicated with a spherical groove; the head end of the lubricating oil filling channel 204 extends to the outside of the shaft sleeve 201, and an inlet is arranged at the head end of the lubricating oil filling channel 204, and a lubricating oil bottle 205 is detachably arranged on the inlet through threaded fitting; the lubricating oil in the lubricating oil bottle 205 enters the lubricating oil filling channel 204, enters the branch channel at the end along the lubricating oil filling channel 204, and enters the spherical groove from the branch channel to replenish the lubricating oil inside the spherical groove.

[0062] Example 2

[0063] Based on the embodiment 1, the function of the auger 1 on the automatic harvester is to separate the crops from the land, and the separated crops enter the next processing link of the harvester, and the separation of the crops by the auger 1 is carried out by the stirring and pulling of the crops by the blades 101 arranged on the surface of the auger 1;

[0064] The surface of the auger blade 101 is usually relatively smooth. If the crops themselves are relatively wet after rain, when the auger 1 is pulling out and separating the crops, the friction between the blade 101 and the crop stem is relatively small, and the rotation and pulling force of the crop stem is insufficient, which may cause the crops to be unable to be pulled out from the ground;

[0065] like Figure 6 As shown, in this embodiment, a plurality of anti-slip spikes 103 are provided on the surface of the blade 101. By adding the anti-slip spikes 103 on the smooth surface of the blade 101, when the blade 101 contacts the crop, the crop stem can be entangled and embedded between the anti-slip spikes 103. On the other hand, during the rotation of the auger, the anti-slip spikes 103 can increase the friction force to prevent the crop stem from slipping with the auger blade 101, which would result in incomplete separation of the stem and spike.

[0066] Example 3

[0067] Based on Example 1, Figure 1 and Figure 5 As shown, the back plate 5 in this embodiment is configured as an arc-shaped structure, the upper edge of the back plate 5 is connected to the bottom of the top plate 4, and the lower edge of the back plate 5 extends to the bottom of the auger 1; a feed port 501 is provided at the connection between the upper edge of the back plate 5 and the top plate 4, and the auger 1 in the feeding assembly realizes primary harvesting of crops and separates the crops from the land, and the separated crops can be guided to the feed port 501 under the rotation conduction of the auger spiral blades 101, and the feed port 501 is connected to the next processing procedure of the feeding assembly, and the separated crops can enter the next process through the feed port 501 for processing.

[0068] A number of back plate grilles 502 are arranged at equal intervals on the back plate 5 below the auger 1. The back plate grilles 502 can screen out some small particles of dirt and dust. When the auger 1 is separating crops, some ears or fruits may fall onto the back plate grilles 502 and be received by the back plate grilles 502. If there is no back plate grille 502 structure, the ears or fruits falling on the back plate 5 may be mixed with a large amount of impurities such as dirt and dust. The screening effect of the back plate grille 502 can screen out most of the fine particles of impurities.

[0069] Example 4

[0070] Based on Example 3, Figure 1 As shown, a grid tube 6 is integrally formed and connected at the lower edge of the back plate 5, and the grid tube 6 is located at the front side of the back plate 5;

[0071] The grid tube 6 is hollow inside and has an open structure at the rear side; a plurality of grids are arranged at equal intervals on the surface of the grid tube 6; the grid tube 6 can better push the crops, and the grid-like structure on the grid tube 6 allows the crop stems to be embedded in the grid-like structure during the pushing process of the crops, so that the ears or fruit parts above can better contact the auger 1, and the auger 1 pulls out and separates the crops;

[0072] During the process of pulling out crops, some crop stems or weeds may fall from the grid tube 6 into the grid tube 6;

[0073] During harvesting operations, after a large number of densely packed crops are harvested, the weeds or crop stalks may not be able to escape from the grid tube 6 in time, and may become entangled in the grid tube 6, or even fill up the grid tube 6; making it impossible for the crops to be harvested to be well embedded in the grid tube 6, and the ears or fruits above cannot fully contact the blade 101 structure of the auger 1.

[0074] As a preferred embodiment, Figure 4 As shown, a central shaft 601 is arranged in the grid tube 6; both ends of the central shaft 601 are rotatably arranged on the side plate 3, and motors for driving the central shaft 601 to rotate are arranged at both ends of the central shaft 601, the motors are arranged on the side plate 3, and the rotors of the motors are connected to both ends of the central shaft 601;

[0075] A plurality of rotating wheels 602 are arranged at equal intervals on the central shaft 601; a lever 603 is arranged on the surface of the rotating wheel 602; and the lever 603 is parallel to the central shaft 601. The motor drives the central shaft 601 to rotate, the central shaft 601 drives the rotating wheel 602 to rotate, and the rotating wheel 602 drives the lever 603 thereon to rotate; the lever 603 can rotate and pull away the crop stems or weeds in the grille tube 6, so that they can quickly escape from the grille tube 6, so that the inside of the grille tube 6 remains in a hollow state, and does not affect the harvesting operation of the crops to be harvested.

[0076] Example 5

[0077] Based on Example 2, Figure 6 As shown, two paddles 104 are symmetrically arranged in the middle position of the auger 1; the paddles 104 can clean the ears or fruits that fall on the back plate grid 502, and through the action of the paddles 104, the ears or fruits are driven to the feed port 501 on the back plate 5, so that these ears or fruits enter the next processing procedure.

[0078] Example 6

[0079] Based on Example 1, during the crop harvesting process, at the position where the auger drive assembly 2 is installed on the side plate 3, crop stems or weeds may be embedded in the connection seam, and may even be embedded in the internal auger shaft 102. As the auger shaft 102 rotates, the auger shaft 102 is stirred and entangled, which may affect the normal rotation of the auger 1;

[0080] like Figure 1 As shown, in this embodiment, a sealing packing ring 208 is provided at the base position of the auger drive assembly 2 and the side plate 3, and the sealing packing ring 208 is used to prevent the branches or weeds of the crops from getting stuck in the gap of the connection.
