Description

Technical Field

[0001] The utility model relates to the technical field of ear picker equipment, in particular to an ear picking frame. Background Art

[0002] A corn harvester is an agricultural machine that can complete multiple operations such as ear picking, stacking, and returning the stalks to the field at one time when the corn is ripe. Process flow: Use the corn harvester to pick ears when the corn is in a growing state (referred to as standing stalk ear picking). Under the action of the ear picking roller and the ear picking board, the ear stalk is broken. Due to the height difference between the inner and outer picking rollers, the ears fall into the ear box. After the ear box is full, the box is opened and stacked. The high-speed rotating cutter cuts the straw from the root and then enters the crushing mechanism to be cut into pieces 3-5 cm long. After being cut, the straw naturally falls to the ground. Then, the ears are transported to the field, peeled by a peeling machine, and threshed after drying.

[0003] Currently, when the existing ear picking frame is connected to the overall frame, it is generally fixedly connected by welding. Although this connection method can increase the connection strength between the ear picking frame and the overall frame, it is not convenient for the later maintenance of the device. Moreover, during the installation process, if there is a deviation, resulting in multiple ear picking frames being in the same plane, it will also affect the ear picking efficiency of the ear picker.

[0044] As Figure 1 - Figure 6 As shown, the ear picking frame proposed in the embodiment of the present utility model includes:

[0045] Multiple groups of ear picking frame groups are arranged in sequence in the first direction on the frame body. The multiple groups of ear picking frame groups are located on the same straight line, and the first direction is the direction parallel to the ground;

[0046] Each group of ear picking frame groups includes a first ear picking frame 1 and a second ear picking frame 2. There is a gap between the first ear picking frame 1 and the second ear picking frame 2. A first pulling stem roller is rotatably arranged on the first ear picking frame 1, and a second pulling stem roller is rotatably arranged on the second ear picking frame 2. The first pulling stem roller and the second pulling stem roller are exposed in the gap, and there is a gap between the first pulling stem roller and the second pulling stem roller. The length of the gap in the first direction is less than the length of the gap in the first direction. The first ear picking frame 1 is used for detachably connecting with the frame body and drivingly connecting the first pulling stem roller with the driving part on the frame body. The second ear picking frame 2 is used for detachably connecting with the frame body and drivingly connecting the first pulling stem roller with the driving part on the frame body.

[0047] Wherein, the driving part drives the first pulling stem roller and the second pulling stem roller so that the first pulling stem roller moves towards each other on the first ear picking frame 1 and the second pulling stem roller moves towards each other on the second ear picking frame 2 for conveying materials.

[0048] Specifically, the frame body is provided with an auger body, and a driving motor body for driving the auger body is arranged on the frame body. A plurality of ear picking frame groups are arranged on the frame body, and the plurality of ear picking frame groups are arranged in sequence along a first direction on the frame body. The first direction is parallel to the ground and is also the extending direction of the auger body. A plurality of ear picking gearbox bodies are arranged on the frame body at intervals along the first direction. The plurality of ear picking frame groups and the auger body are located on the same side of the frame body, and the plurality of ear picking gearbox bodies are located between the auger body and the plurality of ear picking frame groups. Among them, the number of the plurality of ear picking gearbox bodies is adapted to the number of the plurality of ear picking frame groups and corresponds one by one. Each ear picking frame group is connected to the frame body through the corresponding ear picking gearbox, and the adjacent ear picking gearbox bodies are drivingly connected. One of the plurality of ear picking gearboxes is connected to a motor body that provides power.

The gear sections of the first diameter-reducing roller and the second diameter-reducing roller mesh with each other, and there is a certain gap for further advancing the stalks with corn and removing the corn from the stalks. At the same time, the stalks from which the corn has been removed are squeezed. The bases of the first diameter-reducing roller and the second diameter-reducing roller are used to be drivingly connected to the corresponding ear-picking gearbox body, so that the ear-picking gearbox body can drive the first and second diameter-reducing rollers to rotate towards each other on the first ear-picking frame 1 and the second ear-picking frame 2.

[0052] Both the first ear-picking frame 1 and the second ear-picking frame 2 are detachably connected to the corresponding ear-picking gearbox body by means of bolt connection. The ear-picking gearbox bodies are both detachably connected to the frame body by means of bolt connection. This structural design can not only ensure later maintenance, but also, when installing the first ear-picking frame 1 and the second ear-picking frame 2, if the first ear-picking frame 1 and the second ear-picking frame 2 are not in the same plane, appropriate adjustment can be made, effectively solving the technical problems existing in the prior art.
