Description

Technical Field

[0001] This utility model relates to a silage harvester deployment and docking device, belonging to the field of agricultural machinery manufacturing technology. Background Technology

[0002] With the continuous growth in demand for silage, large silage headers are increasingly used to meet the requirements of efficient harvesting. However, due to their large size, the headers usually need to be folded for easy transportation and relocation. When operating in the field, they need to be unfolded again. For example, Chinese patent applications CN202122092557.0 ("Folding Silage Header Frame, Folding Silage Header and Harvester") and CN 202122089633.2 ("A Folding Header Guide Rod Assembly for a Silage Harvester and a Folding Header for a Silage Harvester") both employ a three-section (middle header and left and right headers) two-fold folding method. During unfolding and folding, the unfolding docking device, as a key component for realizing the folding and unfolding functions, not only undertakes the connection task but also disperses and buffers the impact and load on the header during operation, thereby effectively improving the overall working stability of the machine. Existing technologies for connecting folding silage headers use two matching hooks. One hook is fixed to the lifter support on the left and right headers, while the other is fixed to the guide plate on the middle header. The hooks, lifter support, and guide plate are designed as an integral structure. This rigid connection method lacks sufficient tolerance compensation and adjustment space. During the manufacturing and assembly of the silage header, it is difficult to achieve precise alignment of the two hooks, resulting in common misalignment. This problem not only reduces manufacturing and assembly efficiency but also poses a structural safety hazard under long-term high-load operation, thus affecting the equipment's service life. Furthermore, the matching shape of the two hooks in existing technologies is poor, easily leading to unstable connection. Utility Model Content

[0003] The purpose of this utility model is to provide a silage harvester deployment and docking device. The connecting hook 1 on the harvester support and the harvester support are designed as separate structures. Through holes and straight grooves are opened on the harvester support and the connecting hook 1, respectively. The precise docking of the connecting hook 1 on the harvester support and the connecting hook 2 on the guide plate is ensured by adjusting the positioning of the straight groove and the through hole. Tolerance compensation can be performed during the manufacturing and assembly of the silage harvester, improving assembly efficiency and accuracy. At the same time, the matching shape of the connecting hook 1 and the connecting hook 2 is improved to enhance the stability of the connection and solve the above-mentioned technical problems existing in the prior art.

[0004] The technical solution of this utility model is: a silage harvester deployment and docking device, installed between the shovel support and the guide plate of a foldable silage harvester. The shovel support is provided with a first connecting hook, and the guide plate is provided with a second connecting hook that matches the first connecting hook. The surface of the first connecting hook has multiple straight slots, and the shovel support has multiple circular through holes. The straight slots on the first connecting hook and the circular through holes on the shovel support correspond one-to-one and are fixed by bolt assemblies passing through the straight slots and circular through holes, thus connecting the first connecting hook to the shovel support. The relative positions of the support components are positioned. By adjusting the position of the bolt assembly in the straight groove and the circular through hole, the relative position between the connecting hook one and the support component of the harvester can be finely adjusted to adapt to the precise matching of connecting hook one and connecting hook two. The front end of the connecting hook one is provided with an arc-shaped protrusion one and an arc-shaped groove one. The connecting hook two is provided with an arc-shaped groove two that matches the arc-shaped protrusion one and an arc-shaped protrusion two that matches the arc-shaped groove one. The arc-shaped protrusion one is embedded in the arc-shaped groove two, and at the same time, the arc-shaped protrusion two is embedded in the arc-shaped groove one, so as to realize the docking of connecting hook one and connecting hook two.

[0005] Furthermore, after the first connecting hook and the second connecting hook are fully matched, the first connecting hook is welded onto the support of the rice harvester.

[0006] Furthermore, the arc-shaped groove and the arc-shaped protrusion of the first connecting hook are smoothly connected by a transition surface; the arc-shaped groove and the arc-shaped protrusion of the second connecting hook are smoothly connected by a transition surface.

[0007] Furthermore, the width of the second arc-shaped groove is slightly larger than the radial dimension of the first arc-shaped protrusion, so as to facilitate the attachment of the cutting table during the extension process and the separation during the folding process.

[0008] Furthermore, a guide plate rib is welded to the guide plate, a connecting hook is welded to one end of the guide plate rib, and a guide plate mounting plate is welded to the other end of the guide plate rib. The guide plate mounting plate is welded to the intermediate cutting table frame.

[0009] Furthermore, the loader support is connected to the right header frame via a loader support mounting plate at the tail.

[0010] Furthermore, the supporting member of the rice harvester is vertically provided with a welded plate as an integral structure, and the circular through hole is provided on the welded plate. The straight groove on the connecting hook matches the circular through hole on the welded plate.

[0011] Furthermore, the bottom of the welding plate is provided with a trapezoidal groove, the width of which matches the width of the rice lifter support, and the rice lifter support is welded and fixed in the trapezoidal groove at the bottom of the welding plate.

[0012] The beneficial effects of this utility model are as follows: The connecting hook 1 on the silage harvester support is designed as a separate structure from the silage harvester support. Through holes and straight grooves are opened on the silage harvester support and the connecting hook 1, respectively. The precise docking of the connecting hook 1 on the silage harvester support and the connecting hook 2 on the guide plate is ensured by adjusting the positioning of the straight groove and the through hole. Tolerance compensation can be performed during the manufacturing and assembly process of the silage harvester, improving assembly efficiency and accuracy. At the same time, the matching shape of the connecting hook 1 and the connecting hook 2 is improved to enhance the stability of the connection. Attached Figure Description
