Description

Technical Field

[0001] The utility model belongs to the technical field of baling machines, and in particular relates to a baling device for a baling machine. Background Art

[0002] China's agricultural mechanization is becoming increasingly advanced, and a large amount of crops are harvested every year, including forage grass, crop straw, etc. In order to facilitate the subsequent storage and transportation of forage grass, crop straw, etc., balers are needed to be used to pack forage grass or crop straw into high-density bales.

[0003] In the prior art, the baling device continuously performs a reciprocating pendulum motion. Long-term use will cause wear of the rotating parts of the large needle holder, resulting in deviations in the rotation rhythm of the large needle holder. It may happen that the large needle cannot deliver the baling rope to the specific position of the knotter and the knotting operation cannot be completed. Therefore, professionals are required to perform manual adjustments regularly, which not only affects the working efficiency of the baler, but also requires more manpower. Utility Model Content

[0004] The main technical problem to be solved by the utility model is to provide a baling device for a baling machine, which adds a friction damping structure, solves the problem of deviation in the swing rhythm of the large needle, ensures the smooth progress of the knotting operation, and achieves the purpose of saving manpower and time.

[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 large needle rack rotatably mounted in a baling chamber, a pair of large needles being fixed on the large needle rack, both ends of the large needle rack being hingedly mounted on side panels of the baling chamber via hinge shafts, a brake disc being fixedly mounted on one of the hinge shafts, a brake clamping disc being fixedly mounted on the side panels of the baling chamber, the brake clamping disc being clamped on the brake disc, a brake damping pad being respectively fixed on the two inner walls of the brake clamping disc, and the inner wall of each brake damping pad being pressed tightly against the side wall of the brake disc.

[0007] The following is a further optimization of the above technical solution by the utility model:

[0008] The brake clamp comprises a first clamping plate and a second clamping plate which are arranged opposite to each other. The first clamping plate and the second clamping plate are respectively arranged on both sides of the brake disc, and the first clamping plate and the second clamping plate are fixedly mounted on the side plate of the baling chamber through fasteners.

[0009] Further optimization: the first clamping plate and the second clamping plate are jointly provided with a clamping force adjustment component.

[0010] Further optimization: the clamping force adjustment assembly includes a pin rod, which is arranged parallel to the axial direction of the hinge shaft, and is slidably installed on the first clamping plate and the second clamping plate. A stop block is fixed to the end of the pin rod extending out of the first clamping plate, and a threaded rod is fixed to the end of the pin rod extending out of the second clamping plate. A nut is threadedly installed on the threaded rod, and a compression spring is connected between the nut and the outer wall of the second clamping plate, and the compression spring is sleeved on the pin rod.

[0011] Further optimization: the fasteners are fastening bolts, and the fastening bolts are threadedly connected and installed with the side plates of the baling chamber, the first clamping plate and the second clamping plate.

[0012] The utility model adopts the above technical scheme, and has the following beneficial effects: the technical scheme of the utility model is ingenious in conception and reasonable in structure, and a friction damping structure is added between the large needle frame and the side plate of the baling chamber. The setting of the friction damping structure increases the friction resistance when the large needle frame rotates, so that the large needle frame always maintains a steady rhythm to perform pendulum motion, ensuring the consistency of the swinging rhythm of the large needle; at the same time, the consistency of the swinging rhythm of the large needle frame avoids the deviation between the swinging of the large needle frame and the delivery of the baling rope, and the situation that the baling rope cannot be delivered to the specified position of the knotter due to the excessive swinging speed of the large needle frame occurs, thereby ensuring the smooth progress of the knotting operation, and then ensuring the baling work efficiency of the baler.

[0013] In addition, the adjustment operation of the brake caliper on the clamping force of the brake disc is very simple and does not require the operation of a professional. The baler operator can adjust it by himself, thereby achieving the purpose of saving manpower and time.

DETAILED DESCRIPTION

[0020] like Figure 1-Figure 4 As shown together, a baling device for a baler comprises a large needle frame 1 rotatably mounted in a baling chamber, a pair of large needles 2 are fixed on the large needle frame, both ends of the large needle frame 1 are hingedly mounted on the side plate 4 of the baling chamber through hinge shafts 3, a brake disc 5 is fixedly mounted on one of the hinge shafts 3, a brake clamping disc 6 is fixedly mounted on the side plate 4 of the baling chamber, the brake clamping disc 6 is clamped on the brake disc 5, a brake damping plate 7 is respectively fixed on the two inner walls of the brake clamping disc 6, and the inner wall of each brake damping plate 7 is pressed tightly against the side wall of the brake disc 5.

[0021] During the operation of a traditional baler, the large needle frame 1 performs a reciprocating pendulum motion under the driving action of the baler power system. After long-term use, the hinges of the large needle frame 1 may be worn, resulting in a difference between the swing rhythm of the large needle frame 1 and the conveying rhythm of the baling rope. The provision of the brake disc 5 and the brake clamp 6 in the utility model increases the friction of the rotation of the large needle frame 1, so that the large needle frame 1 can maintain a stable and uniform swing, thereby ensuring the consistency of the swing rhythm of the large needle 2, solving the problem of deviation in the swing rhythm of the large needle 2, and thus enabling the knotting operation to be carried out smoothly and smoothly, thereby ensuring the baling efficiency of the baler.

[0022] like Figure 3 and Figure 4 As shown together, the brake clamp 6 includes a first clamping plate 61 and a second clamping plate 62 which are arranged opposite to each other. The first clamping plate 61 and the second clamping plate 62 are respectively arranged on both sides of the brake disc 5 , and the first clamping plate 61 and the second clamping plate 62 are fixedly mounted on the baling chamber side plate 4 through fasteners 63 .

[0023] like Figure 3 As shown, a clamping force adjustment assembly 64 is provided on the first clamping plate 61 and the second clamping plate 62 .

[0024] Among them, the clamping force adjustment component 64 includes a pin rod 641, which is arranged parallel to the axial direction of the hinge shaft 3, and the pin rod 641 is slidably installed on the first clamp plate 61 and the second clamp plate 62. A stop block 642 is fixed to the end of the pin rod 641 extending out of the first clamp plate 61, and a threaded rod 643 is fixed to the end of the pin rod 641 extending out of the second clamp plate 62. A nut 644 is threadedly installed on the threaded rod 643, and a compression spring 645 is commonly connected between the nut 644 and the outer wall of the second clamp plate 62, and the compression spring 645 is sleeved on the pin rod 641.

[0025] In this embodiment, the clamping force of the first clamping plate 61 and the second clamping plate 62 on the brake disc 5 is adjusted by screwing the nut 644 to move the position of the threaded rod 643. If it is necessary to increase the friction resistance of the large needle holder 1 during rotation, the operator only needs to screw the nut 644 inward, and the nut 644 compresses the compression spring 645. The elastic force of the compression spring 645 increases, thereby increasing the clamping force between the second clamping plate 62 and the first clamping plate 61, thereby increasing the friction resistance of the brake damping pad 7 to the side wall of the brake disc 5.

[0026] On the contrary, if it is necessary to reduce the frictional resistance of the large needle holder 1 during rotation, the operator only needs to screw the nut 644 outward, the length of the compression spring 645 increases, that is, the elastic force decreases, thereby reducing the clamping force between the second clamping plate 62 and the first clamping plate 61, thereby reducing the frictional resistance of the brake damping pad 7 to the side wall of the brake disc 5.

[0027] The fastener 63 is a fastening bolt, and the fastening bolt is threadedly connected to the baling chamber side plate 4, the first clamping plate 61 and the second clamping plate 62.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
