Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a gear picking machine. Background Art

[0002] In the daily work process, it is often necessary to use some picking devices to pick out block objects from the soil or other powdery objects. For example, in the breeding process, it is necessary to regularly clean the block objects in the cowshed. The existing cleaning method is mostly manual cleaning, which is time-consuming and labor-intensive, with high labor intensity and low efficiency. At the same time, some herders use dung shovels for cleaning, that is, the lower part of the common forklift bucket is changed to a hollow design, but the effect is not significant in actual use. The bucket will shovel away the powdery and blocky objects on the cowshed floor together with the blocky objects. The powdery and blocky objects on the cowshed floor have a heat-insulating effect. Without heat preservation, the cows will catch a cold when lying down, which is not conducive to breeding. Utility Model Content

[0026] Combined with attachment Figure 1-Figure 5 and Figure 7 A tooth picking machine includes a bucket assembly and a picking assembly arranged on the bucket assembly. The bucket assembly adopts an existing bucket, including a bucket body 1, a bucket hollow net arranged on the bucket body 1, and bucket teeth installed at the front end of the bucket hollow net.

[0027] The picking assembly includes a connecting drive part installed on the bucket body 1 and located at the front end thereof, and a gear shifting assembly provided on the connecting drive part. The connecting drive part drives the gear shifting assembly to rotate and transports block objects on the ground toward the bucket. The connecting drive part includes a main shaft connecting rod 2 fixedly connected to the bucket body 1 and provided on both sides thereof. A gear housing mechanism is respectively provided on the two main shaft connecting rods 2. A transmission main shaft 6 is provided between the two sets of gear housing mechanisms. The transmission main shaft 6 is keyed with the internal gear housing 5 on both sides. A motor 3 is provided on one of the main shaft connecting rods 2. One end of the transmission main shaft 6 passes through the gear housing mechanism and the main shaft connecting rod 2 and is connected to the transmission shaft of the motor 3. Two sets of connecting rod structures are respectively provided on each set of gear housing mechanisms to connect with the gear shifting assembly.

[0028] Each gear housing mechanism includes an outer gear housing 4 fixedly connected to the main shaft connecting rod 2, an inner gear housing 5 is rotatably provided on the outer gear housing 4, a small half gear 18, a large half gear 17 and a limiting slide 19 are provided on the outer gear housing 4, a complete gear 21 that can mesh with the small half gear 18 and the large half gear 17 is provided on the inner gear housing 5, a limiting protrusion 16 that cooperates with the limiting slide 19 is provided on the complete gear 21, a connecting shaft 8 that passes through the inner gear housing 5 is fixed on the complete gear 21, and the main shaft connecting rod 2 is used to support and fix the gear housing mechanism to ensure that the gear housing mechanism can work stably.

[0029] The connecting rod structure includes a first connecting rod 7 connected to the connecting shaft 8 and arranged in a Z shape. A second connecting rod 9 is rotatably provided on the first connecting rod 7. Two second connecting rods 9 are provided, one of which is fixedly connected to the connecting shaft 8 or key-matched. The second connecting rod 9 is rotatably connected to the side of the first connecting rod 7 away from the first connecting rod 7 with a third connecting rod 10. The third connecting rod 10 is connected to the gear shifting assembly. The gear shifting assembly includes a mounting plate 11 fixedly connected to the third connecting rod 10. A plurality of gear shifting units are installed on the mounting plate 11 in an array along its long side direction. The second connecting rod 9, the third connecting rod 10 and the gear shifting assembly are each provided in two groups, all of which are provided on the first connecting rod 7 and are centrally symmetrically arranged.

[0030] The tooth-picking unit includes a fixing seat 12, which is U-shaped and has an opening at the front end. A slot is provided on the fixing seat 12 on the side opposite to its opening. A limit pin 15 is provided on the fixing seat 12, which passes through the opposite side walls thereof. A tooth 13 and a torsion spring 14 are rotatably provided on the limit pin 15. The tooth 13 is arranged in the fixing seat 12, and one of the extension arms of the torsion spring 14 abuts against the mounting plate 11, and the other extension arm abuts against the side wall of the tooth 13. A limit hole is provided on the limit pin 15, and an elastic limit member 20 is inserted in the limit hole. When the resistance of the frozen block object to the tooth 13 is greater than the elastic force of the torsion spring 14, the tooth 13 will rotate along the pin shaft, thereby avoiding the frozen block object. When encountering a block object that is not frozen to the bottom surface, the force exerted on the tooth 13 is less than the elastic force of the torsion spring 14, and the tooth 13 deflects without making a sound, and the block object will be pushed into the bucket.

[0031] The motor 3 is used to provide power to drive the transmission main shaft 6 to rotate clockwise. The rotation of the transmission main shaft 6 drives the internal gear housing 5 on both sides to rotate, thereby driving the internal gears to rotate in coordination, and then driving the gear shifting assembly to move through the connecting rod structure.

[0032] like Figure 4As shown, when the transmission main shaft 6 drives the entire picking assembly to rotate counterclockwise, and at the same time drives the inner gear housing 5 and the full gear 21 to rotate counterclockwise to A, the limiting protrusion 16 on the full gear 21 slides out of the limiting slide groove 19 on the outer gear housing 4, and engages with the small half gear 18 at the same time, and the full gear 21 rotates counterclockwise at the same time, and then drives the connecting shaft 8 to rotate counterclockwise, so that the second connecting rod 9 drives the third connecting rod 10 and the gear shifting assembly to rotate upward circumferentially along the connecting shaft 8, so that the third connecting rod 10 and the gear shifting assembly gradually perform a lifting movement, and when the transmission main shaft 6 drives the inner gear housing 5 and the full gear 21 to rotate to B, the full gear 21 disengages from the small half gear 18 and engages with the large half gear. The gear 17 is engaged and rotates clockwise, driving the second connecting rod 9 to rotate clockwise through the connecting shaft 8, so that the third connecting rod 10 and the shifting gear assembly gradually move downward. When the transmission main shaft 6 drives the inner gear housing 5 and the complete gear 21 to rotate to C, the complete gear 21 is disengaged from the large half gear 17, and the two limiting protrusions 16 on the complete gear 21 slide into the limiting slide groove 19, so that the complete gear 21 cannot rotate on its own and revolves around the transmission main shaft 6 with the outer gear housing 4. The entire process of the gear housing from A to C changes the contact between the sowing teeth and the ground from a point to a line. A plurality of parallel shifting teeth 13 form a rectangular surface together, which effectively sends the block object to one side of the bucket, so that the bottom end of the shifting tooth 13 is as shown in FIG. Figure 6 The trajectory shown.

[0033] The above description of the present invention and its embodiments is non-limiting. What is shown in the full text is only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
