Description

Technical Field

[0001] The utility model belongs to the technical field of baling machines, and in particular relates to a rope box turning device and a large square bale baling machine. Background Art

[0002] A large square baler is an agricultural machine that collects and compresses straw (corn, wheat, rice, etc.) or forage into bales. It is primarily used in alfalfa-producing areas such as the grasslands of Inner Mongolia and Gansu, as well as in corn stalks and wheat straw in winter wheat regions of Northeast China. Large square balers offer high efficiency, high bale density, low transportation costs, labor savings, and a high level of intelligence, representing a significant product development trend. The baler's rope box, a key component for tying ropes, serves as a rope guide and holds the rope. To improve operational continuity and reduce the frequency of rope changes, large square baler boxes are typically larger. However, the symmetrically arranged large rope boxes obscure most of the transmission and working components, making maintenance (such as timing adjustment, roller clearance adjustment, and tie rod length adjustment) difficult. Currently, there are two main methods for mounting a baler's rope box: the first is secured to the machine using bolts and nuts; the second is a latched connection between the rope box and the bracket. Currently, large square rope boxes are large in size, so the first solution is used; small square rope boxes are smaller in size and weight, so the second solution can also be used. However, both solutions are fixed connections, and when the machine needs maintenance, the rope box needs to be removed, making maintenance more difficult. Utility Model Content

[0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and to provide a rope box turning device and a large square bundle baler. The device is rationally optimized in structure and a specific structure is designed to give the rope box a turning function, so that the position adjustment of the rope box is fast and convenient, safe and stable, and convenient for maintenance of the equipment, which improves the convenience of equipment maintenance to a certain extent.

[0004] One of the purposes of the present utility model is to provide a rope box flipping device, comprising a rope box support mechanism and a rope box, wherein the rope box is installed on the rope box support mechanism, and the rope box can move between at least a stowed position and an expanded position. In the stowed position, the front end of the rope box is connected to the rope box support mechanism through a rotatable mechanism, and the tail end of the rope box can be fastened to the stowed position by a fixing member. The rope box can be rotated from the stowed position to a predetermined expanded position by a certain angle through the rotatable mechanism, and the rope box is fixed in the expanded position.

[0005] As a preferred embodiment, it also includes a rope box locking mechanism for fixing the rope box in the expanded position, and the rope box locking mechanism includes a safety strut, one end of the safety strut is fixed to the rope box, and the other end can be connected to or separated from the fixed connecting piece of the rope box support mechanism; or one end of the safety strut is fixed to the rope box support mechanism, and the other end can be connected to or separated from the fixed connecting piece of the rope box.

[0006] As a preferred solution, a pin hole I is formed at the free end of the safety strut, and the pin hole I of the safety strut is connected to the fixed connector through a pin shaft; a bracket hole that cooperates with the pin hole I is provided on the fixed connector, and the pin shaft passes through the bracket hole and the pin hole I to lock the position of the rope box.

[0007] As a preferred solution, the fixed connecting member includes an upper connecting member and a lower connecting member, the upper connecting member is provided with an upper bracket hole, the lower connecting member is provided with a lower bracket hole, and the center axes of the upper bracket hole and the lower bracket hole coincide with each other.

[0008] As a preferred solution, a limiting slot for limiting the position of the safety strut is further provided on one side of the fixed connection member.

[0009] As a preferred solution, the lower end of the pin shaft is provided with a pin hole II for inserting an elastic pin.

[0010] As a preferred solution, the upper and lower sides of the tail of the rope box are fixedly connected to the frame through an upper support frame and a lower support frame respectively.

[0011] As a preferred solution, the rope box support mechanism includes a rope box support frame, the rope box support frame includes a support frame column and an upper support assembly and a lower support assembly arranged on the support frame column, the upper support assembly and the lower support assembly are used to be connected to the frame, and the support frame column is connected to the rope box through a rotatable mechanism.

[0012] A second object of the present utility model is to provide a large square bundle baler, comprising a frame and a rope box turning device as described in any one of the above.

[0013] As a preferred solution, the number of the rope box turning devices is two, and the rope box turning devices are symmetrically arranged on both sides of the frame.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] First, this solution improves the structure so that the rope box can be fixed on the frame and can also be rotated along the rotating connection on the frame. The rope box can move between a stowed position and an expanded position. Retracted position: To ensure normal operating conditions, the rope box needs to be fixed in the stowed position (working position). At this time, the rope box cannot be rotated relative to the frame to ensure the stability of the rope supply. Expanded position: During maintenance, the fixed plate at the tail of the rope box needs to be removed. At this time, the rope box is only connected to the frame through a rotatable mechanism. The rope box can be rotated around the rotatable mechanism at a certain angle to the expanded position, thereby exposing the transmission parts and working parts of the frame for easy repair and maintenance, which improves the maintenance efficiency to a certain extent and reduces the work intensity.

[0016] Secondly, the present invention also takes into account that after the rope box is unfolded, it is necessary to ensure that the rope box is fixed in the unfolded position to prevent the rope box from moving around the rotation axis. Therefore, a rope box locking mechanism is also provided. By installing the fixing effect of the support rod, the rope box is fixed in a specific position in the unfolded state and prevented from moving in the unfolded position, thereby avoiding equipment and personal safety hazards during maintenance. By fixing the rope box in a certain position, the reliability and safety during maintenance are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1

[0033] As shown in the figure, this embodiment provides a rope box flipping device, including a rope box support mechanism 3 and a rope box 2 installed on the rope box support mechanism 3. The rope box 2 can move between at least a stowed position and an expanded position. In the stowed position, the front end of the rope box 1 is connected to the rope box support mechanism 3 through a rotatable mechanism 7, and the tail of the rope box 1 can be fastened to the frame 1 by a fixing part. When equipment maintenance is required, the tail of the rope box 2 is disassembled from the fixing part of the frame 1, so that the tail of the rope box 2 can be rotated a certain angle away from the frame 1 to a predetermined expanded position through the rotatable mechanism 7, and the rope box 2 is fixed in the expanded position. Therefore, the rope box 2 has two position states. During normal operation, the rope box 2 is fixed in the retracted position. At this time, the rope supply of the rope box 2 is stable. When the parts of the vehicle body need to be inspected, the connector at the rear of the rope box 2 is disassembled and separated, so that the rope box 2 can be rotated to a certain angle relative to the rope box support mechanism 3 through the rotatable mechanism 7 to reach the predetermined inspection position (deployed position). In this position state, it is convenient to carry out repairs and maintenance, which helps to improve the efficiency of maintenance work and reduce work intensity.

[0034] In this solution, the rope box support mechanism 3 includes a support frame column 31 and a rope box support frame, wherein the rope box support frame is used to fix the support and be installed on the frame 1, and the rope box support frame includes an upper support assembly 32 and a lower support assembly 34, wherein the upper support assembly 32 includes a support rib plate I 321, a support rib plate II 322 and a support rib plate III 323, and the support rib plate I 321, the support rib plate II 322 and the support rib plate III 323 are arranged in sequence from back to front (with the positive direction of the frame 1 as the front end).

[0035] In this embodiment, one end of the support rib plate I 321 is fixed on the support frame cross bar 324, one end of the support rib plate III 323 is connected to the upper end of the support frame column 31, the support frame cross bar 324 is vertically connected to the upper end of the support frame column 31, the support rib plate II 322 is located between the support rib plate I 321 and the support rib plate III 323, and the upper end of the support rib plate II 322 is fixed to the upper end of the support frame column 31. Preferably, the support rib plate I 321, the support rib plate II 322 and the support rib plate III 323 are all arranged perpendicular to the support frame column 31 as a whole, and the support rib plate I 321, the support rib plate II 322 and the support rib plate III 323 are fixedly connected. The lower support assembly 34 comprises a lower support rod 341, and the two ends of the lower support rod 341 are provided with a slot for the cross bar 325 to pass through, and the second ends of the upper support rods 1321, the lower support rods 2322 and the lower support rods 323 are provided with an end fixing plate connected to the frame 1, and the end fixing plates of the upper support rods 1321 and the upper support rods 323 are provided with a position adjustment hole 326 connected to the frame 1, which not only facilitates the installation of the support rods and the frame 1, but also facilitates the adjustment of the installation position of the support rods and the frame 1, reducing the installation difficulty and precision requirements between the two. The rope box support mechanism 3 is connected to the frame 1 through three upper connection points and one lower connection point, which is used to support the rope box 2. The above rope box support mechanism 3 structural design not only helps to reduce the difficulty of manufacturing parts, but also can achieve the purpose of convenient assembly.

[0036] In order to improve the overall strength and support stability of the rope box support mechanism 3, this solution is also provided with a reinforcing support 33. The lower end of the reinforcing support 33 is connected to the support frame column 31 through the end plate I331, and the upper end of the reinforcing support 33 is connected to the support rib of the upper support assembly 32 through the end plate II332. For example, the reinforcing support 33 is connected to the support rib I321 and the support rib II322. Preferably, the support rib I321 and the support rib III323 are both connected to the support frame column 31 through the reinforcing support 33, which can further improve the overall strength and support stability of the rope box support mechanism 3.

[0037] In this solution, the support ribs I 321, the support ribs II 322, the support ribs III 323 and the lower support rod 341 are all detachably connected to the frame 1, so that the rope box support mechanism 3 is supported at four points and is firmly installed; the support ribs I 321 and the support ribs III 323 are provided with position adjustment holes 326, and the position adjustment holes 326 are waist-shaped holes, so that the installation position of the rope box 2 can be adjusted, thereby improving assembly efficiency.

[0038] In this embodiment, the rotatable structure 7 can be implemented as follows: it includes a support plate 72 arranged on the support frame column 31 and a plurality of supports 71 arranged on the support plate 72, the supports 71 are fixed on the support plate 72 and arranged in an array, the center lines of the axial holes of the supports 71 coincide with each other, and a shaft sleeve 73 is provided on one side panel of the rope box 2. The shaft sleeve 73 can be installed between the two supports 71, so that the tube cavity of the shaft sleeve 73 corresponds to the axial hole of the support 71, and the rotating shaft 74 is inserted, and the axial position of the rotating shaft 74 is limited by inserting the cotter pin 75 into the pin holes at both ends of the rotating shaft 74. Specifically, there are four groups of supports 71, and the center lines of the shaft holes of the four groups of supports 71 are coaxial. The purpose of this design is to help enhance the processing accuracy of parts and reduce assembly errors. The two upper supports 71 are one group, and the two lower supports 71 are another group. There are two shaft sleeves 73 of the rope box 2, of which the upper shaft sleeve 73 is installed between the two supports 71 in the upper group, and the lower shaft sleeve 73 is installed between the two supports 71 in the lower group, thereby limiting the installation height position of the rope box 2.

[0039] In this solution, the shaft sleeve 73 is fixed to the outer wall of one side of the rope box 2 through the hinge plate 76. In order to improve the connection strength, a reinforcing plate 77 is also provided at the connection between the shaft sleeve 73 and the hinge plate 76. One side of the reinforcing plate 77 is fixed on the hinge plate 76, and the other side is fixed on the shaft sleeve 73. Preferably, the reinforcing plates 77 are provided in two or more groups and are distributed along the axial direction of the shaft sleeve 73. Such a design helps to enhance the connection strength between the shaft sleeve 73 and the hinge plate 76.

[0040] In this embodiment, after the rope box 2 is rotated to a predetermined position, it needs to be positioned and fixed to ensure the safety of personnel and equipment during operation. Therefore, it is necessary to fix the deployed position of the rope box 2. This solution also provides a rope box locking mechanism 4, which includes a safety support rod 41. One end of the safety support rod 41 is fixed to the rope box 2, and the other end can be connected to or separated from the rope box support mechanism 3, thereby fixing the rope box 2 in the deployed position or unlocking it from the deployed position.

[0041] In this solution, the rope box locking mechanism 4 can be implemented as follows: the rope box locking mechanism 4 includes a safety strut 41, one end of the safety strut 41 needs to be fixed on the rope box 2, and the other end is a free end, which is used to be fixedly connected to the rope box support mechanism 3. Specifically, the free end of the safety strut 41 is provided with a pin hole Ⅰ 411, and the rope box support mechanism 3 is provided with a fixed connector 42 connected to the pin hole Ⅰ 411 of the safety strut 41, and the fixed connector 42 includes an upper connector 421 and a lower connector 422, wherein the upper connector 421 is provided with a pin hole Ⅰ 411. There is an upper bracket hole, and a lower bracket hole is provided on the lower connecting member 422. When the rope box 2 is rotated to a certain angle to a predetermined position, the free end of the safety strut 41 will enter between the upper connecting member 421 and the lower connecting member 422, and then pass through the upper bracket hole, pin hole I411 and the lower bracket hole in sequence through the pin shaft 43, so as to fix the rope box 2 in the predetermined deployment position, thereby improving the stability and safety of the device during maintenance. Specifically, the upper connecting member 421 can be set to a pin shaft sleeve as shown in the figure, and the lower connecting member 422 can be set to a connecting hole plate as shown in the figure.

[0042] In order to further facilitate the position correspondence between the pin hole Ⅰ411 of the safety strut 41 and the bracket hole of the fixed connector 42, a limiting slot 44 can be further provided on one side of the fixed connector 42. The limiting slot 44 is opened on the card plate on one side of the fixed connector 42. The free end of the safety strut 41 enters between the limiting slots 44, thereby smoothly realizing the position alignment of the pin hole Ⅰ411 with the upper bracket hole and the lower bracket hole, thereby facilitating the insertion of the pin shaft 43.

[0043] Taking into account the problem that after the pin shaft 43 is installed, the insertion end is not restricted and may accidentally fall off after being touched, a pin hole II is also provided at the insertion end of the pin shaft 43. By inserting an elastic pin 45 into the pin hole II, the pin shaft 43 is locked to prevent the pin shaft 43 from accidentally falling off and to prevent the rope box 2 from moving in the expanded position.

[0044] As shown in the figure, in order to ensure the installation angle of the safety strut 41, a strut connecting plate 46 is also provided at the tail of the safety strut 41. The tail of the safety strut 41 is fixed to the rope box 2 through the strut connecting plate 46, so that the free end of the safety strut 41 has a certain inclination angle, which is convenient for connecting with the fixed connector 42.

[0045] It should be pointed out that in an embodiment not shown in the drawings, the tail of the safety strut 41 can also be set on the rope box support mechanism 3, and the fixed connecting piece 42 is set on the rope box 2, so that locking is achieved by fixing the free end of the safety strut 41 to the fixed connecting piece 42, which can also achieve the locking effect of the unfolded position of the rope box 2.

[0046] In this solution, when the rope box 2 is flipped to a certain angle, the safety strut 41 is located in the limit slot 44, the center line of the hole of the upper connecting part 421, the center line of the hole of the safety strut 41, and the center line of the hole of the lower connecting part 422 are coaxial, and the pin 43 is sleeved in the holes of the upper connecting part 421, the safety strut 41, and the lower connecting part 422, and the position of the safety strut 41 is limited by the elastic pin 45.

[0047] Example 2

[0048] This embodiment provides a large square bale baler, comprising a frame 1 and the rope box turning device 10 described in Example 1. As shown, two rope box turning devices 10 are provided, symmetrically arranged on either side of the frame 1: one on the left side of the frame 1 and one on the right side of the frame 1, with the forward direction of the frame 1 being the front side. The rope box turning devices 10 employ a symmetrical mounting structure, which reduces the difficulty of manufacturing and processing parts and improves assembly efficiency.

[0049] In this embodiment, when the rope box 2 is in the stowed position, the front end of the rope box 2 is connected to the frame 1 via the rotating shaft 74 and the rope box support mechanism 3, and the rear end of the rope box 2 is connected to the frame 1 via the upper connecting frame 5 and the lower connecting frame 6. Specifically, the upper and lower sides of the rear end of the rope box 2 are fastened to the frame 1 via the upper connecting frame 5 and the lower connecting frame 6, respectively, thereby achieving a single-point fixation of the front end of the rope box 2 and a two-point fixation of the rear end of the rope box 2.

[0050] When the rope box 2 needs to be flipped to the unfolded position, it needs to be achieved through the cooperation of the rope box support mechanism 3, the rotatable mechanism 7 and the rope box locking mechanism 4. The rope box 2 rotates around the rotating shaft 74 and rotates to the predetermined unfolded position. The rope box 2 is locked in the unfolded position through the rope box locking mechanism 4.

[0051] The specific operation process of adjusting the rope box 2 is as follows: when the whole machine is in operation, the rope box 2 is in the retracted position, the upper connecting frame 5 and the lower connecting frame 6 of the rope box 2 are respectively connected to the frame 1, the tail of the rope box 2 forms a two-point fixation, and the front of the rope box 2 forms a single-point fixation through the rotatable mechanism 7. These three points work together to realize the fixation of the rope box 2. At this time, the rope box locking mechanism 4 is not working.

[0052] When repairing the entire machine, the upper connecting frame 5 and the lower connecting frame 6 need to be disassembled and separated from the frame 1 respectively, and the rope box 2 is rotated around the rotating shaft 74 to the predetermined unfolding position. The safety strut 41 is located in the limit slot 44, and the center line of the hole of the upper connecting part 421, the center line of the hole of the safety strut 41, and the center line of the hole of the lower connecting part 422 are almost coincident. The pin shaft 44 is sleeved in the holes of the upper connecting part 421, the safety strut 41, and the lower connecting part 422. The elastic pin 45 is installed in the pin hole II to limit the position of the safety strut 41, thereby realizing the locking of the rope box 2 position. At this time, the maintenance position of the baler is exposed to facilitate maintenance. At the same time, the rope box 2 is locked to ensure the safety of people and equipment during the maintenance process.

[0053] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
