Description

Technical Field

[0001] This utility model relates to the field of picking device technology, and in particular to a picking device for loading and unloading alfalfa bales. Background Technology

[0002] Alfalfa is a perennial flowering plant. The most famous variety is purple alfalfa, which is used as pasture and livestock feed. However, existing alfalfa bale loading and unloading devices are prone to detaching during the picking process, and lack a mechanism to push the bales during unloading, making the unloading of alfalfa bales inconvenient.

[0003] Chinese Patent No. CN221719914U discloses an alfalfa bale loading and unloading device, relating to the field of alfalfa bale loading and unloading technology. This utility model includes an L-shaped mounting plate; a first insert plate is fixedly connected to one side of the L-shaped mounting plate, the top surface of the first insert plate has an arc-shaped groove; a lifting plate is slidably connected to one side of the L-shaped mounting plate; a second insert plate is fixedly connected to one side of the lifting plate; a motor is fixedly connected to one side of the L-shaped mounting plate, the drive end of the motor is fixedly connected to a lead screw rotatably connected to the L-shaped mounting plate; the lifting plate is threaded onto the circumferential side of the lead screw; a fixing plate is fixedly connected to one side of the L-shaped mounting plate, and a toothed plate extending through to the top of the second insert plate is fixedly connected to the top surface of the fixing plate. This utility model, through the movement of the second insert plate and the arc-shaped plate, quickly completes the picking and unloading of alfalfa bales, ensuring the stability of the alfalfa bales during the picking and handling process, and the unloading process, coordinated with the pushing of the arc-shaped plate, makes the unloading of alfalfa bales more convenient and faster.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the above solutions use a pressing method to compress alfalfa hay for easy handling. In actual use, since the above devices use a simple vertical compression method, the alfalfa hay will loosen and spring back after the pressure plate is released, thus causing it to loosen again.

[0026] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0027] Example 1

[0028] like Figures 1-3 As shown in the figure, in order to solve the existing problems, this utility model discloses an alfalfa bale loading and unloading picking device, including a base 1 and a support rod 2 connected to its top. The support rod 2 is connected to a housing 3 at its top. The bottom of the housing 3 is arc-shaped. A transmission component 4 is connected to the side of the housing 3. A swing component 5 is connected to the other side of the housing 3. A winding component 6 is connected to the side of the housing 3.

[0029] The transmission component 4 includes a motor bracket 401 connected to the side of the housing 3. The motor bracket 401 is connected to a rotating motor 402. The output end of the rotating motor 402 is connected to a transmission pulley 403. The transmission pulley 403 is connected to a transmission belt 404.

[0030] The drive belt 404 is connected to a driven pulley 405 at one end away from the drive pulley 403. The driven pulley 405 is provided with a connecting shaft, and a sliding member 406 is rotatably connected to the outer arc surface of the connecting shaft.

[0031] The winding component 6 includes a sliding groove 604 disposed on the side of the housing 3. A rotating shaft 601 is slidably connected to the inner wall of the sliding groove 604. A winding roller 603 is rotatably connected to the rotating shaft 601. A limit buckle 602 is rotatably connected to the outer arc surface of the rotating shaft 601. The diameter of the limit buckle 602 is larger than the width of the inner wall of the sliding groove 604. A disassembly groove 605 is provided on the other side of the housing 3. The width of the disassembly groove 605 is larger than the outer diameter of the winding roller 603. Flexible winding claws distributed in a circular pattern are provided on the outer diameter of the winding roller 603.

[0032] The housing 3 has an arc-shaped groove 407 on its side. The connecting shaft is slidably connected to the inner wall of the arc-shaped groove 407. The sliding member 406 is slidably connected to the side of the housing 3. The diameter of the sliding member 406 is larger than the inner diameter of the arc-shaped groove 407. One end of the connecting shaft is connected to an extrusion roller 408.

[0033] The specific working principle is as follows: This device can effectively improve the efficiency of bale processing of alfalfa. In actual use, the alfalfa raw material is put into the housing 3 from the top, thereby achieving the processing effect of alfalfa. When the alfalfa is put into the housing 3 from the top, the rotating motor 402 is started, which drives the transmission belt 404 through the transmission pulley 403, thereby realizing the rotation of the driven pulley 405. Since the transmission pulley 403 is located at the center of the arc-shaped groove 407, the transmission belt 44 will not loosen during the swinging process.

[0034] On the other side, the housing 3 can drive the connector 502 to slide via the electric telescopic rod 501, thereby achieving the sliding effect of the rack 503. The rack 503 can drive the gear 504 to rotate synchronously, thus achieving the symmetrical squeezing effect of the squeezing rollers 408 on both sides. At this time, after the alfalfa raw material enters the housing 3, it contacts the winding roller 603 under the guidance of the squeezing roller 408 and is wrapped on the surface of the winding roller 603. As the alfalfa enters, the winding diameter becomes larger and larger. At this time, the squeezing roller 408 swings downward, which can squeeze the roller and make the wrapped alfalfa more compact, ensuring tighter bundling and improving storage efficiency.

[0035] After the winding is completed, the limiting buckle 602 is removed and the winding roller 603 is pulled out from the side of the disassembly groove 605. Finally, the sliding plate is unfolded and the straw roller is discharged from the bottom outlet to achieve material discharge.

[0036] Example 2

[0037] like Figures 1-3 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above embodiment one, the alfalfa bale loading and unloading picking device further includes: the swinging component 5 includes an electric telescopic rod 501 connected to the side of the housing 3, the telescopic end of the electric telescopic rod 501 is connected to a connector 502, the connector 502 is slidably connected to the side of the housing 3, the connector 502 is connected to a rack 503, the rack 503 is meshed with a gear 504, the gear 504 is rotatably connected to the housing 3, the side of the gear 504 away from the housing 3 is connected to a swing rod 505, the end of the swing rod 505 away from the gear 504 is connected to a transmission rod 506, and the transmission rod 506 is rotatably connected to the squeezing roller 408.

[0038] The specific working principle is as follows: This device can achieve the effect of winding and bundling alfalfa raw materials. Compared with the traditional simple pressing and storage effect, the rotation and winding method can reduce the risk of accidental loosening of alfalfa raw materials during subsequent transportation, improve the stability of transportation, and this device can control the density of alfalfa straw rollers according to the degree of compression of the extrusion roller 408.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
