TECHNICAL FIELD
[0001] The present application relates to the technical field of square bale baler, in particular to a bale rectifying mechanism for square bale pickup. BACKGROUND
[0002] The square bale baler can pick up, stack, extrude and bundle small square bales into large square bales. The large square bales can be directly transported to a board car with a grab bucket and hoisting equipment, which is convenient for transportation. Only one person is needed to complete the pickup and bundling operation, the cost is much lower than that of a large square bale baler, the operation efficiency is improved, and the cost is greatly reduced.
[0003] However, the existing square bale baler has at least the following defects and deficiencies in completing the square bale pickup operation with the traditional bale pickup device: the traditional bale pickup device needs manual assistance when picking up the bale, for example, when the bale is not placed correctly, the pickup device cannot correct the bale, resulting in the bale being obliquely clamped between the left and right guide plates of the pickup device, so that the bale cannot be smoothly picked up. When this happens, manual assistance is needed to straighten the bale before the bale can be picked up, which wastes labor and reduces work efficiency. SUMMARY
[0004] To overcome the above-mentioned deficiencies of the prior art, the present application provides a bale rectifying mechanism for a square bale pickup device, which straightens the bale on the ground that is inclined to the entrance of the square bale pickup device, so that the bale is straight to the entrance of the square bale pickup device.
[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:
[0006] A bale rectifying mechanism for a square bale pickup device, the mechanism is arranged in pairs and symmetrically installed on both sides of the bale entrance of the square bale pickup device; it comprises a connecting seat, a guide plate and a spring; the connecting seat is fixedly connected to the bale entrance column of the square bale pickup device; the guide plate is hingedly connected to the connecting seat; one end of the spring is connected to the guide plate, and the other end is connected to the connecting seat.
[0007] Further, the connecting seat comprises an upper connecting plate, a lower connecting plate and a shaft sleeve; the upper connecting plate and the lower connecting plate are fixedly connected to the upper and lower ends of the shaft sleeve; the guide plate is hingedly connected to the shaft sleeve through a connecting shaft.
[0008] Further, the upper connecting plate and the lower connecting plate are each provided with an opening corresponding to the bale entrance column of the square bale pickup device, and the openings of the upper connecting plate and the lower connecting plate are fixedly connected to the column.
[0009] Further, the lower connecting plate is provided with an extension rod, and the extension rod is provided with a spring hook.
[0010] Further, the guide plate comprises a main body, an upper hinged plate, a lower hinged plate and a spring seat; the upper hinged plate and the lower hinged plate are fixedly connected to the upper and lower ends of one side of the main body, and the spring seat is fixedly connected to the lower end of one side of the main body.
[0011] Further, the upper hinged plate and the lower hinged plate are both provided with through holes corresponding to the connecting shaft, and are hinged on the connecting shaft through the through holes.
[0012] Further, the spring seat comprises an upper plate and a lower plate, and a bolt is installed on the upper plate and the lower plate; both ends of the spring are provided with hanging rings, one end of the hanging ring is sleeved on the bolt, and the other end of the hanging ring is hung on the spring hook.
[0013] Further, it further comprises a limiting pin, which is vertically installed on the spring seat and limits the spring.
[0014] Further, the main body is a vertically arranged plate provided with an outward bending; the plate is divided by the bending into a rectangular end connected with a square bale pickup bale inlet stand and a trapezoidal other end, and the width of the other end gradually decreases.
[0015] Compared with the prior art, the present application has the following advantages:
[0016] 1. The present application is arranged in pairs and symmetrically installed on both sides of the square bale pickup bale inlet; even if the bale is placed obliquely on the ground, when the vertical side of the bale hits the guide plate, the guide plate is impacted and expanded outward (rotates outward), and the maximum expansion reaches the limiting position. When expanded, the spring is stretched to store a certain amount of energy, and then this energy is rapidly released under the action of the spring tension, that is, the spring rapidly contracts, thereby driving the guide plate to retract inward (rotate inward), and the guide plate hits the vertical side of the bale to rotate the bale, so that the bale returns to the state of being placed directly opposite the inlet, and the bale is aligned. The present application can automatically restore the bale to the correct placement position, thereby realizing normal bale pickup of the square bale pickup, and the present application does not need manual assistance to align the bale, thereby saving labor and improving the pickup efficiency.
[0017] 2. The connecting seat of the present application comprises an upper connecting plate, a lower connecting plate and a shaft sleeve, the upper connecting plate and the lower connecting plate are fixedly connected to the upper and lower ends of the shaft sleeve, and the guide plate is hinged on the shaft sleeve through the connecting shaft. The upper and lower ends of one side of the guide plate are both provided with hinge points, and the load is transmitted through the upper and lower hinge points, thereby avoiding excessive local stress caused by single-point stress, reducing the risk of fatigue fracture and prolonging the service life. Double hinging can share the bending moment, and especially when a transverse force or eccentric load is borne, the structural stability is significantly improved.
[0018] 3、The upper connecting plate and the lower connecting plate are provided with corresponding openings corresponding to the bale inlet column of the square bale pickup, and the openings of the upper connecting plate and the lower connecting plate are fixed to the column. The openings of the upper and lower connecting plates and the geometric shape of the column are strictly matched (such as rectangular, U-shaped or V-shaped openings), forming a mechanical hard limit, which ensures that the precise centering can be realized without repeated adjustment during installation.
[0019] 4、The present application is provided with a limiting pin, which is vertically installed on the spring seat to limit the spring. The limiting pin directly blocks the swing path of the guide plate, ensuring that its maximum swing angle does not exceed the design threshold, avoiding overload swing caused by excessive spring force or external impact. Limiting the swing range can prevent accidental collision between the guide plate and adjacent components.
[0020] 5、The shape of the symmetrically arranged guide plates simulates the state of human arms holding, thereby enhancing the holding adaptability, smoothness and stability through bionics. BRIEF DESCRIPTION OF DRAWINGS

[0038] As shown in Figure 3 The connecting seat 1 includes an upper connecting plate 11, a lower connecting plate 12 and a shaft sleeve 13. The shaft sleeve 13 is a hollow cylinder and is vertically arranged. The upper connecting plate 11 and the lower connecting plate 12 are fixedly connected to the upper and lower ends of the shaft sleeve 13. The upper connecting plate 11 and the lower connecting plate 12 are both provided with a rectangular gap 14 corresponding to a square bale pickup bale inlet stand 6. The rectangular gap 14 of the upper connecting plate 11 and the lower connecting plate 12 is welded to the stand 6. The lower connecting plate 12 is provided with an extension rod 15, and the end of the extension rod 15 is provided with a spring hook 16.
[0039] The rectangular gap 14 of the upper connecting plate 11 and the lower connecting plate 12 and the geometric shape of the rectangular stand 6 are strictly matched to form a mechanical hard limit, which ensures that accurate centering can be achieved without repeated adjustment during installation.
[0040] As shown in Figure 4As shown, the guide plate 2 comprises a main body 21, an upper hinge plate 22, a lower hinge plate 23, and a spring seat 24. The main body 21 is a vertically mounted plate with an outward bend. The bend divides the plate into a rectangular shape at the end connected to the bale inlet column of the square bale picker, and a trapezoidal shape at the other end, with the width gradually decreasing. Hinge points are located at both the upper and lower ends of one side of the guide plate 2. Loads are transmitted through these hinge points, preventing excessive local stress caused by single-point force, reducing the risk of fatigue fracture, and extending service life. The double hinges share bending moment, significantly improving structural stability, especially when subjected to lateral forces or eccentric loads.
[0041] The upper hinge plate 22 and the lower hinge plate 23 are fixed to the side where the main body 21 is connected to the bale entrance column of the square bale picker. Figure 4 The middle part is the upper and lower ends of the left side, and the spring seat 24 is fixedly connected to the lower end of the left side of the main body 21. The upper hinge plate 22 and the lower hinge plate 23 are both provided with a through hole corresponding to the connecting shaft 5.
[0042] The spring seat 24 includes an upper plate 25 and a lower plate 26. The upper plate 25 and the lower plate 26 are provided with mounting holes for bolts 27 and mounting holes for limit pins 4. The bolts 27 and the limit pins 4 are both vertically mounted on the upper plate 25 and the lower plate 26. The bolts 27 are located in front of the limit pins 4.
[0043] like Figure 5 As shown, the connecting shaft 5 includes a shaft body 51 and an end plate 52 . The end plate 52 is fixed to the upper end of the shaft body 51 , and a bolt hole is provided on the end plate 52 .
[0044] like Figure 1 、 Figure 2 As shown, the rectangular notches 14 of the upper connecting plate 11 and the lower connecting plate 12 of the connecting base 1 are welded to the upright post 6 at the bale entrance of the square bale picker, thereby fixing the connecting base 1 to the upright post 6. The shaft 51 of the connecting shaft 5 passes through the upper hinge plate 22, the upper connecting plate 11, the shaft sleeve 13, the lower connecting plate 12, and the lower hinge plate 23 in sequence. The end plate 52 of the connecting shaft 5 is bolted to the upper hinge plate 22, thereby hingedly connecting the guide plate 2 to the connecting base 1. The connecting shaft 5 rotates with the guide plate 2, and the guide plate 2 rotates around the axis of the connecting shaft 5.
[0045] Both ends of the spring 3 are provided with hanging rings 31, one end hanging ring is sleeved on the bolt 27 of the spring seat 24, and the other end hanging ring 31 is hung on the spring hook 16 at the end of the extension rod 15 of the lower connecting plate 12.
[0046] like Figure 6-9 As shown, the working principle and working process of the present invention are as follows:
[0047] like Figure 6As shown, the two guide plates 2 are arranged in pairs and symmetrically installed on both sides of the square bale pickup bale inlet, the two guide plates 2 arranged in pairs are in a spreader shape, and simulate the state of human arms holding, thereby enhancing the holding adaptability, smoothness and stability.
[0048] When the bale 7 on the ground is placed obliquely, the vertical side of the bale hits the guide plate 2 on one side, the guide plate 2 is impacted and rotates outward to apply a force to the spring 3, and is maximally spread to a limiting position, the spring 3 is stretched to store a certain amount of energy when being spread, and then the energy is rapidly released under the action of the spring tension, that is, the spring is rapidly contracted.
[0049] As shown, Figure 7 When the guide plate 2 rotates inward under the action of the spring 3 tension, the guide plate 2 hits the vertical side of the bale, drives the bale 7 to rotate, and restores the bale to a state of being placed opposite to the inlet, thereby aligning the bale. The present application automatically restores the bale 7 to a normal placement position, thereby realizing normal bale pickup of the square bale pickup. The present application does not need manual assistance to align the bale, saves labor, and improves the pickup efficiency.
[0050] Figure 8 The limiting position for outward rotation and spreading of the present application, Figure 9 The limiting position for inward rotation of the present application, the limiting pin 4 directly blocks the swing path of the guide plate 2, ensures that the maximum swing angle does not exceed the design threshold, and avoids overload swing caused by excessive spring force or external impact. Limiting the swing range can prevent accidental collision between the guide plate and adjacent components.
[0051] The above is only part of the specific embodiments of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
