Description

Technical Field

[0001] The utility model belongs to the technical field of harvesting and baling devices, and specifically relates to a baling device for a baler. Background Art

[0002] The square hay baler is a forage harvesting machine that is driven by a tractor. It mainly includes a traction beam, a screw conveyor, a feeding device, a picker, a baling device and a baling device. The picker is used to pick up the straw laid on the ground and lift it to the screw conveyor. The screw conveyor is used to collect the hay laterally and collect it into the feeding chamber. At the same time, the feeding device runs according to a predetermined trajectory to add the hay accumulated in the feeding chamber into the baling chamber from the feeding port below the baling chamber. The baling device compresses the hay in the baling chamber and finally ties the compacted hay into neat and regular bales with baling ropes.

[0003] In the Chinese utility model patent application number 202221732401.2, a baler piston cylinder support bearing and a baler are proposed. The patent has the following main problems: the baler in the patent adopts a single bearing wheel to support the baler piston cylinder. The single wheel support structure and the track in the baling chamber are single-point supported, and the support stability is relatively poor. In addition, in the existing balers, the grass guide is welded and fixed on the inner wall of the baling chamber. If the grass guide is damaged or deformed, it is difficult to repair. Utility Model Content

[0004] The main technical problem to be solved by the utility model is to provide a baling device for a baler, which adopts a double-wheel support structure and a detachable grass guide to achieve reliable support for the piston cylinder, and has a simple structure and is convenient for subsequent maintenance operations.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A baling device for a baler comprises a baling body, a baling chamber is arranged in the baling body, two oppositely arranged grass guides are arranged in the baling chamber, the two grass guides are respectively installed on the two inner side walls of the baling chamber through fasteners, a baling mechanism is arranged on one side of the two grass guides, and the baling mechanism is slidably installed in the baling chamber along the grass guiding direction of the grass guides;

[0007] The baling mechanism comprises a piston cylinder slidably mounted in the baling chamber, a baling rod is mounted at the center of the piston cylinder, a pressing plate is fixed to one end of the baling rod away from the piston cylinder, and a double wheel support assembly is arranged on one side of the baling rod.

[0008] The following is a further optimization of the above technical solution by the utility model:

[0009] Each of the grass guides includes a guide plate, each of which extends along the sliding direction of the piston cylinder, and a material pressing gap is formed between the two guide plates. An inclined plate is fixed to the outer wall of each guide plate at one end away from the piston cylinder, and a fixed seat is fixed to the end of each inclined plate away from the guide plate. Each fixed seat is pressed against the inner wall of the baling chamber, and each fixed seat is detachably mounted on the baling body through a plurality of fasteners.

[0010] Further optimization: one end of each inclined plate is welded and fixed to the guide plate, and the other end of each inclined plate is welded and fixed to the fixing plate.

[0011] Further optimization: the double-wheel support assembly includes a guide angle frame, which extends along the sliding direction of the piston cylinder. One end of the guide angle frame is installed on the piston cylinder, and a fixed bracket is fixed to the other end of the guide angle frame. A pair of support rollers are rotatably installed on the fixed bracket.

[0012] Further optimization: each of the support rollers is rotatably mounted on an axle rod, and each axle rod is mounted on a fixed bracket.

[0013] Further optimization: each of the supporting rollers is a bearing wheel.

[0014] The utility model adopts the above technical scheme, which is ingenious in conception and reasonable in structure. The double-wheel support structure adopted increases the contact area between the outer peripheral surface of the support roller and the surface of the track in the baling chamber to improve the supporting stability of the double-wheel support assembly on the piston cylinder, thereby effectively slowing down the wear speed of the outer peripheral surface of the support roller, and there is no need to frequently replace the components of the baling device. At the same time, compared with the single-wheel support structure in the traditional baler, the supporting strength of the double-wheel support assembly is higher. Even if one of the supporting rollers cannot be used due to wear or external force, the other supporting roller can continue to support the piston cylinder, avoiding the situation where the piston cylinder loses control and is damaged due to sudden failure of the supporting roller, thereby ensuring the operating stability and safety of the baling device.

[0015] The grass guide is detachably installed in the baling chamber by fasteners. When the grass guide is squeezed and deformed by hard objects such as stones, maintenance personnel can directly remove the deformed grass guide for replacement. The replacement operation is simple, the maintenance speed is fast, and the maintenance cost is low.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In this embodiment, the position of the pressing gap 32 corresponds to the position of the baling rod 52 , and the baling rod 52 continuously passes through the pressing gap 32 to complete the pressing operation.

[0033] Moreover, one end of each inclined plate 33 is welded and fixed to the guide plate 31 , and the other end of each inclined plate 33 is welded and fixed to the fixing seat 34 .
