Description

Technical Field

[0001] This utility model relates to a tracked self-propelled square bale baler, and more particularly to a transport device for the tracked self-propelled square bale baler. Background Technology

[0002] Existing square balers only perform baling. After baling, the bales are placed in the field, and then collected and transported by a special baler. However, the fields are muddy, and the transporter, which does not have a tracked self-propelled function, cannot go into the field to collect and transport the bales.

[0003] Furthermore, the traditional grass collection frame uses bolts to connect the main body and the extension part, resulting in a small overall space, inconvenient assembly, poor structural stability, and cumbersome unfolding / folding operations.

[0004] There is an urgent need in the market for a square bale baler that can both bale and transport bales in the field. Summary of the Invention

[0005] This utility model provides a foldable hay collection frame structure suitable for conveying hay bales in a tracked self-propelled square hay baler.

[0006] A foldable hay collection frame structure for a tracked self-propelled square hay baler includes a main hay collection frame welded body and a foot pedal welded body, wherein the bottom plate of the hay collection frame welded body and the bottom plate of the foot pedal welded body are connected by two sets of hinge assemblies.

[0007] The foot pedal is welded to the outside with a vertical connecting rod one and a vertical connecting rod two;

[0008] The vertical connecting rods on one side of the movable door (203) and the foot pedal weld (202) are connected by two sets of hinges; the vertical connecting rod on the other side is connected to the movable door 203 by a pin, connecting the two vertical connecting rods into a whole.

[0009] The middle part of the welded grass collection frame railing is connected to the middle part of the two vertical connecting rods via two upper connecting rod hinges; two sets of steel wire ropes are connected to the outer edge of the foot pedal welded to the middle part of the welded grass collection frame railing via ring buckles.

[0010] Furthermore, a hook is provided on the outer side of the grass collection frame pin of the aforementioned foot pedal.

[0011] Furthermore, a limiting block is provided on the second grass collection frame pin between the base plate of the grass collection frame welded body and the base plate of the foot pedal welded body.

[0012] A tracked self-propelled square bale baler, characterized in that the square bale baler is provided with a foldable bale collection frame structure including any one of the above.

[0013] Beneficial effects: 1. The linkage design of the connecting rod and hinge enables the rapid folding and unfolding of the grass collection frame; the limit block and wire rope design structure improves the stability and load-bearing capacity.

[0014] Folding reduces volume during transport, while unfolding increases capacity.

[0015] Tracked self-propelled square balers facilitate the movement of balers in the fields and transport them to roads, preventing other transport machinery from getting stuck in the mud. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be further described in conjunction with the accompanying drawings:

[0027] See Figure 1This is a diagram showing the usage state of the welded body of the grass collection frame of the tracked self-propelled square baler of this utility model. The foldable grass collection frame 2 is placed on one side of the baler of the tracked self-propelled square baler 1.

[0028] See Figure 2 and Figure 3 The foldable grass collection frame 2 is mainly composed of two parts: the main grass collection frame welded body 201 and the foot pedal welded body 202. The bottom of the main grass collection frame welded body 201 and the bottom of the foot pedal welded body 202 are connected by hinges.

[0029] See Figure 3 , 4 5, 6, 7, Two sets of hinges 207 connect the grass collection frame welded body 201 and the foot pedal welded body 202; the end of the foot pedal welded body 202 is connected to two vertical connecting rods 1 205 and vertical side rod 212 through two sets of hinges 207. One of the vertical connecting rods has a hinged movable door 203, and the other vertical connecting rod is connected to the movable door 203 through a pin, connecting the two vertical connecting rods into a whole;

[0030] The upper connecting rod 204 is hinged to the middle of the grass collection frame welded body 201 and the middle of the vertical connecting rod 205, with its movable door 203 located at the upper end of the upper connecting rod 204. The two vertical connecting rods can rotate around the foot pedal welded body 202. The steel wire rope 214 is connected to the middle of the grass collection frame welded body 1 and the outer end of the foot pedal welded body 2 via a ring. The limiting block is welded to the grass collection frame pin connection of the hinge of the grass collection frame welded body 1. The outward extension of the upper connecting rod 204 coincides with the projection of the foot pedal welded body 2 in its horizontal position, limiting the unfolding angle of the foot pedal welded body 2. This makes the foot pedal welded body 2 horizontal in use and vertical after retraction.

[0031] The hydraulic cylinder 213 is located at the bottom of the folding grass collection frame 2, and the hydraulic cylinder 213 is used as a flipping device for the entire grass collection frame.

[0032] Specifically, the folding / unfolding mechanism:

[0033] When folding, the foot pedal weld 202 and the entire movable door 203 are pushed upwards. Due to the presence of the hinge and upper connecting rod 204, when the foot pedal weld 202 rotates, the entire movable door 203 moves upwards with the rotation. When the foot pedal weld 202 is perpendicular to the bottom plate of the grass collection frame weld 201, the upper connecting rod 204 fits against the railing of the grass collection frame weld 201, completing the folding action. The foot pedal weld 202 is equipped with a grass collection frame pin 209, which is used to fix the hook (hook 206). The hook 206 is connected and fixed to the end of the railing of the grass collection frame weld 201, forming a frame structure with a smaller space, so as to reduce the space occupied when folded.

[0034] When unfolded, the tower buckle (hooking 206) is opened, and the foot pedal welding 202 rotates downward. The limiting block 214, which is fixed by the weed collection frame pin 210 at the bottom of the weed collection frame welding body 201, restricts the position. The foot pedal welding 202 is horizontal with the bottom plate of the weed collection frame welding body 201. The upper connecting rod 204 pulls the railing of the weed collection frame welding body 201. The steel wire rope 214 connects the railing of the weed collection frame welding body 201 to the end of the foot pedal welding 2, which also restricts the rotation angle of the foot pedal welding 2.

[0035] Technical Description: A hinged folding hay bale collection frame structure includes a main hay bale collection frame welded body 201, a foot pedal welded body 202, a movable door 203, two vertical connecting rods, an upper connecting rod, and steel wire ropes. The base plate of the hay bale collection frame welded body 201 is connected to the foot pedal welded body 202 by two sets of hinge assemblies. One vertical connecting rod of the foot pedal welded body 202 and the movable door 203 are also connected by two sets of hinges. The middle part of the railing of the hay bale collection frame welded body 201 is connected to the middle parts of the two vertical connecting rods by hinges 7, respectively. Two sets of steel wire ropes 211 are connected to the outer edge of the foot pedal welded body 2 and the middle part of the railing of the hay bale collection frame welded body 201 by ring buckles, forming a triangular stable structure. After the movable door 203 is opened, the folding hay bale collection frame 2 pours out the hay bales under the drive of the hydraulic cylinder 213.

[0036] Innovation points:

[0037] Features include unique hinge structures, linkage mechanisms, and a double-safety design using limit blocks and wire ropes.

[0038] Beneficial effects

[0039] The linkage design of the connecting rod and hinge enables the rapid folding and unfolding of the grass collection frame; the limit block and steel wire rope design improves the stability and load-bearing capacity.
