Description

Technical Field

[0001] The utility model relates to the technical field of fork loader attachments, in particular to a multi-purpose fork loader attachment. Background Technique

[0002] The telescopic boom fork loader is suitable for use in multiple fields and working conditions. As the professionalism and versatility of the attachment are particularly important, it can effectively broaden the use range of the whole machine, improve the utilization rate and operation efficiency, and put forward higher requirements.

[0003] At present, the following problems still exist in the fork loader attachments:

[0004] 1. The fork needle attachments configured on the existing fork loaders are basically fixed. When forking and loading bales of straw, if the bales of straw are not placed correctly, at this time, it is necessary to push the skewed corner of the bale of straw to adjust it through the fork. At this time, the fork needle of the attachment cannot be turned up and will fork into the bale of straw again to push, which is very easy to damage the integrity of the bale of straw.

[0005] 2. In addition, the heights of the bales of straw are different. The existing fork loader attachments are basically of a fixed height. When it comes to higher bales of straw, it is very difficult for the fork to support the bales of straw, reducing the universality of the fork loader attachment. Summary of the Utility Model

[0006] In view of the above problems, the present invention provides a multi-purpose fork loader attachment, which has the advantages of pin flipping, shelf height adjustment, etc.

[0007] The technical solution it adopts is that the utility model includes a shelf placed at the front end of the telescopic boom. The shelf includes two symmetrically distributed fixed frames. Two vertically arranged support frames are fixed between the two fixed frames. Two symmetrically distributed vertical rods are fixed between the two support frames. A connecting frame located below the support frames is fixed between the two fixed frames. The connecting frame is fixedly connected with the telescopic boom;

[0008] A cross beam located below the connecting frame is fixed between the two fixed frames. A plurality of equally spaced mounting plates are fixed on the front side of the cross beam. Two symmetrically distributed positioning plates are fixed on the mounting plate. The same rotating shaft is rotatably connected to a plurality of the positioning plates. A plurality of connecting blocks are fixed on the rotating shaft. The plurality of connecting blocks are respectively located between two adjacent positioning plates. A pin is fixed on the connecting block. The pin is of a conical structure and the diameter of the end far from the connecting block is the smallest. A limiting block is fixed on the front side of the mounting plate;

[0009] Both ends of the rotating shaft are coaxially fixed with connecting discs. Connecting rods are fixed at the outer edges of the connecting discs. Two symmetrically distributed spring cylinders are fixed on the cross beam. A piston plate is slidably connected inside the spring cylinder. The piston plate is connected to the spring cylinder by a spring. A connecting shaft is coaxially fixed on the piston plate. Two symmetrically distributed positioning blocks are fixed on the cross beam. The two connecting shafts are respectively slidably connected to the corresponding positioning blocks. One end of the connecting shaft away from the piston plate is rotatably connected to an intermediate rod. One end of the intermediate rod away from the connecting shaft is rotatably connected to the connecting rod.

[0010] Preferably, a top block is threadedly connected to one end of the spring cylinder away from the connecting shaft. A compression spring is arranged between the piston plate and the top block. The compression spring contacts the top block. One end of the top block away from the compression spring is coaxially fixed with an adjusting rod. A handle is coaxially fixed on the adjusting rod.

[0011] Preferably, the tops of the two fixing frames are inserted with the same C-shaped beam. A jack is formed through one side of the fixing frame. The C-shaped beam includes an intermediate beam and two insertion arms inserted into the corresponding fixing frames. A plurality of equally spaced connecting holes are respectively formed on the two insertion arms. Pins passing through the jacks and the connecting holes are inserted into both fixing frames.

[0012] Preferably, a plurality of round rods matching the pins are fixed between the two support frames. A collar is slidably connected to the round rod. A waist-shaped groove is formed on the collar.

[0013] Preferably, two symmetrically distributed hooks are fixed on the lower support frame.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Through the settings of the limit block, rotating shaft, connecting block, etc., when the hay bale is not placed properly, the telescopic arm drives the shelf to lift upward, so that the pin is located directly above the hay bale. Then the shelf is slowly lowered. Under the action of the hay bale, the pin flips upward. When the shelf descends to the side of the hay bale, the telescopic arm pushes the shelf to correct the hay bale. After the correction is completed, the telescopic arm drives the shelf to move backward. Under the action of gravity, the pin returns to the horizontal state again. Then the pin can be inserted into the hay bale, effectively preventing the binding rope of the hay bale from breaking when the fork pushes the hay bale and the pin directly inserts into the hay bale.

[0016] 2. Through the settings of the connecting disc, spring cylinder, piston plate, etc., when the pin flips, the turntable rotates, causing the intermediate rod to push the connecting shaft to slide. When the piston plate slides in the spring cylinder, the spring provides a buffering effect to prevent the pin from being rigidly damaged due to excessive flipping force.

[0017] 3. Through the settings of the C-shaped beam, jacks, and pins, etc., the worker can pull out the pins on the two fixing brackets and then raise or lower the height of the C-shaped beam. After the height adjustment is completed, insert the pins into the jacks again, so that the shelf can be adjusted for bales of different heights. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.

[0028] By Figures 1 to 5Provided is a shelf disposed at the front end of the telescopic arm 1. The shelf includes two symmetrically distributed fixed frames 2. The fixed frame 2 is a hollow structure. Between the two fixed frames 2, two support frames 3 arranged vertically are fixed. Between the two support frames 3, two symmetrically distributed vertical rods 4 are fixed. Between the two fixed frames 2, a connecting frame 5 located below the support frame 3 is fixed. The connecting frame 5 is fixedly connected to the telescopic arm 1. When in use, the telescopic arm 1 drives the shelf to move towards the bale, and the insertion pin 11 can be inserted into the bale;

[0029] Between the two fixed frames 2, a cross beam 6 located below the connecting frame 5 is fixed. On the front side of the cross beam 6, a plurality of equally spaced mounting plates 7 are fixed. In this embodiment, the number of mounting plates 7 is three. On the mounting plate 7, two symmetrically distributed positioning plates 8 are fixed. The positioning plate 8 is fixedly connected to the connecting frame 5. The same rotating shaft 9 is rotatably connected to a plurality of the positioning plates 8. A plurality of connecting blocks 10 are fixed on the rotating shaft 9. The number of the connecting blocks 10 is the same as that of the mounting plates 7. A plurality of the connecting blocks 10 are respectively located between two adjacent positioning plates 8. An insertion pin 11 is fixed on the connecting block 10. The insertion pin 11 is of a conical structure and the diameter of the end far from the connecting block 10 is the smallest. A limiting block 12 is fixed on the front side of the mounting plate 7. The limiting block 12 is of a triangular or trapezoidal structure. The limiting block 12 is used to limit the maximum turning angle of the insertion pin 11, so that the maximum turning angle of the insertion pin 11 is 89 degrees and is in a certain inclined state. However, this inclined state will not affect the pushing of the bale. Through the settings of the limiting block 12, the rotating shaft 9 and the connecting block 10, when the bale is not placed properly, the telescopic arm 1 drives the shelf to lift upwards, so that the insertion pin 11 is located directly above the bale, and then the shelf is slowly lowered. The insertion pin 11 is turned upwards under the action of the bale. When the shelf descends to the side of the bale, the telescopic arm 1 pushes the shelf to correct the bale. After the correction is completed, the telescopic arm 1 drives the shelf to move backward, and the insertion pin 11 returns to the horizontal state under the action of gravity, and then the insertion pin 11 can be inserted into the bale, effectively preventing the binding rope of the bale from breaking when the fork pushes the bale and the insertion pin 11 directly inserts into the bale;

[0030] Considering that when the pin 11 flips under its own gravity, it carries a large amount of gravitational potential energy, which is not convenient for controlling the force when the pin 11 flips. In the long run, it will affect the service life of the pin 11. Both ends of the rotating shaft 9 are coaxially fixed with connecting discs 13. An outer edge of the connecting disc 13 is fixed with a connecting rod 14. Two symmetrically distributed spring cylinders 15 are fixed on the cross beam 6. A piston plate 16 is slidably connected in the spring cylinder 15. The piston plate 16 is connected to the spring cylinder 15 by a spring. A connecting shaft 17 is coaxially fixed on the piston plate 16. Two symmetrically distributed positioning blocks 18 are fixed on the cross beam 6. The two connecting shafts 17 are respectively slidably connected to the corresponding positioning blocks 18. One end of the connecting shaft 17 away from the piston plate 16 is rotatably connected to an intermediate rod 19. One end of the intermediate rod 19 away from the connecting shaft 17 is rotatably connected to the connecting rod 14. Through the settings of the connecting disc 13, the spring cylinder 15 and the piston plate 16, etc., when the pin 11 flips, the rotation of the turntable causes the intermediate rod 19 to push the connecting shaft 17 to slide. When the piston plate 16 slides in the spring cylinder 15, the spring provides a buffering effect to prevent the pin 11 from being rigidly damaged due to excessive flipping force of the pin 11.

[0031] Reference Figure 4 and Figure 5 As shown, in order to facilitate adjusting the compression amount of the spring inside the spring cylinder 15 and further adjusting the flipping speed of the pin 11, a top block 20 is threadedly connected to one end of the spring cylinder 15 away from the connecting shaft 17. A compression spring 21 is arranged between the piston plate 16 and the top block 20. The compression spring 21 contacts the top block 20. One end of the top block 20 away from the compression spring 21 is coaxially fixed with an adjusting rod 22. A handle 23 is coaxially fixed on the adjusting rod 22. Through the settings of the top block 20, the compression spring 21 and the handle 23, etc., a worker can directly rotate the handle 23 to drive the top block 20 to move inside the spring cylinder 15. The deeper the top block 20 penetrates into the spring cylinder 15, the slower the flipping speed of the pin 11, improving the safety when the pin 11 flips.

[0032] Reference Figure 1 and Figure 6 As shown, in order to facilitate adjusting the height of the shelf to be applicable to bales of various heights, the tops of the two fixing frames 2 are plugged with the same C-shaped beam 24. One side of the fixing frame 2 is penetrated and provided with a jack. The C-shaped beam 24 includes an intermediate beam and two insertion arms inserted into the corresponding fixing frames 2. A plurality of equally spaced connecting holes are respectively formed in the two insertion arms. Plug pins 25 penetrating the jacks and the connecting holes are plugged on both of the fixing frames 2. Through the settings of the C-shaped beam 24, the jacks and the plug pins 25, etc., a worker pulls out the plug pins 25 on the two fixing frames 2 and then raises or lowers the height of the C-shaped beam 24. After the height adjustment is completed, the plug pins 25 are inserted into the jacks again.

[0033] ReferenceFigure 1 and Figure 7 As shown in Figure 7 , when the fork is not in use, in order to facilitate the fixation of the insertion pin 11, a plurality of round rods 26 matching the insertion pin 11 are fixed between the two support frames 3. A collar 27 is slidably connected to the round rod 26. A waist-shaped groove 28 is formed in the collar 27. The insertion pin 11 is located in the waist-shaped groove 28. When the insertion pin 11 is in normal use, the collar 27 rotates to the side away from the insertion pin 11. When fixing the insertion pin 11, the collar 27 rotates and is sleeved on the insertion pin 11 from top to bottom.

[0034] Refer to Figure 1 As shown in Figure 1 , two symmetrically distributed lifting hooks 29 are fixed on the lower support frame 3 for lifting the ton bag. Under normal conditions, the lifting hooks 29 are located on the side away from the insertion pin 11. Only when lifting the ton bag, the lifting hooks 29 are unfixed and flipped, and then fixed after flipping.

[0035] When the present utility model is in use:

[0036] First, during normal use, the telescopic arm 1 drives the shelf to move towards the bale, and the insertion pin 11 can be inserted into the bale;

[0037] Then, when encountering the situation that the bales are not placed correctly, the telescopic arm 1 drives the shelf to lift upwards, so that the insertion pin 11 is located directly above the bale, and then the shelf is slowly lowered. The insertion pin 11 is flipped upwards under the action of the bale. When the shelf descends to the side of the bale, the telescopic arm 1 pushes the shelf to correct the bale. After the correction is completed, the telescopic arm 1 drives the shelf to move backward, and the insertion pin 11 returns to the horizontal state under the action of gravity, and then the insertion pin 11 is inserted into the bale;

[0038] Secondly, when the insertion pin 11 is flipped, the turntable rotates so that the middle rod 19 pushes the connecting shaft 17 to slide. When the piston plate 16 slides in the spring cylinder 15, the spring provides a buffering effect;

[0039] Finally, when encountering bales with a relatively high height, the worker pulls out the pins 25 on the two fixing frames 2 and then raises the height of the C-shaped beam 24. After the height adjustment is completed, the pins 25 are inserted into the jacks again.

[0040] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
