Description

Technical Field

[0001] The utility model relates to the technical field of crop straw pulling devices, in particular to a crop straw pulling device. Background Art

[0002] Crops refer to plants planted and cultivated by humans for use as food, feed, fiber and industrial raw materials. However, after certain crops such as cotton, soybeans, and corn are harvested, the crop stalks will remain in the land. The retained stalks need to be pulled out by workers to facilitate the reuse of the land. In the prior art, the stalks are often pulled out manually or by tools by workers. Manually pulling out the stalks requires frequent bending, which in turn causes harm to the workers' bodies. Traditional tools require more operating steps to pull out the stalks, such as first confining the structure inside the device, clamping the stalks with a clamping mechanism, and finally pulling out the structure through a driving mechanism. Under a large amount of work, the workload of the workers is increased and the efficiency of pulling out the straw is reduced. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a technical solution, a crop straw pulling device, comprising:

[0025] See also Figure 1 The base 1 has a push rod 2 fixedly connected to the right side of the top of the base 1, which facilitates driving the base 1 to move. The top of the base 1 is slidably connected to a splint 3, which can pull out the straw. The top of the splint 3 is evenly spaced and penetrated with round arms 31.

[0026] The bottom of the circular arm 31 is connected to the top of the base 1. The circular arm 31 can guide the splint 3 to make the splint 3 move in a straight line. The splint 3 and the top of the base 1 are both provided with grooves 11. The grooves 11 facilitate the splint 3 and the base 1 to wrap the straw inside. The bottom of the splint 3 is evenly connected with second springs 6. The bottom of the second spring 6 is connected to the top of the base 1. The second spring 6 can pull the splint 3 back to its original position after the movement is completed.

[0027] See also Figure 2 The transmission mechanism 4 is installed inside the push rod 2. The transmission mechanism 4 includes a pedal 41. The pedal 41 is convenient for the staff to drive. The front and back sides of the pedal 41 are connected with a spherical bearing 42 with a seat. The spherical bearing 42 with a seat supports and connects the pedal 41. The spherical bearing 42 with a seat is connected to the inside of the push rod 2.

[0028] A first spring 43 is connected to the bottom of the pedal 41, and the first spring 43 can pull the pedal 41 to return to its original position. A cross-connecting plate 44 is connected to the bottom of the first spring 43, and the cross-connecting plate 44 supports the first spring 43. The cross-connecting plate 44 is connected to the inside of the push rod 2. Pull ropes 45 are connected to the front and back of the bottom of the pedal 41.

[0029] Pulleys 411 are connected to the front and back of the left side of the push rod 2 at equal intervals through seat bearings. The seat bearings are connected to the push rod 2 through a cross plate. The outside of the pulley 411 is connected to the pull rope 45. The pulley 411 can guide the pull rope 45. The bottom of the pull rope 45 is connected to the top of the splint 3.

[0030] See also Figure 3 The clamping mechanism 5 is installed on the front and back sides of the clamping plate 3. The clamping mechanism 5 includes a threaded rod 51. The threaded rod 51 can drive the nut 52 to move. The outer part of the threaded rod 51 is sleeved with a first spherical bearing 511. The first spherical bearing 511 is connected to the clamping plate 3 through a through connection. The first spherical bearing 511 can support and limit the threaded rod 51.

[0031] The external thread of the threaded rod 51 is connected to a nut 52, which can drive the L-shaped arm 53 to move. The L-shaped arm 53 is connected to both sides of the end of the nut 52 close to the clamping plate 3. The L-shaped arm 53 is connected with the clamping plate 3 through a through connection. The L-shaped arm 53 can transmit power to the pressure plate 54, and the L-shaped arm 53 can guide the nut 52 to prevent the nut 52 from rotating during movement. The end of the L-shaped arm 53 close to the clamping plate 3 is connected to the pressure plate 54, which is used to clamp straw.

[0032] One end of the pressing plate 54 away from the L-shaped arm 53 is fixedly connected with a rubber pad 541, which is a square rubber plate. The rubber pad 541 prevents the pressing plate 54 from cutting off the straw when clamping the straw. The outer part of the threaded rod 51 is sleeved with a gear 55, which transmits power to the threaded rod 51.

[0033] The outside of the gear 55 is meshedly connected with a tooth plate 56, which transmits the gear 55. The bottom of the tooth plate 56 is connected to the top of the base 1. The top of the outside of the tooth plate 56 is not provided with teeth, so that after the pressure plate 54 clamps the straw, the transmission mechanism 4 can no longer exert force when it continues to rise, thereby avoiding cutting off the straw.

[0034] This solution first pushes the base 1 so that the groove 11 is set on the outside of the straw, and then the pedal 41 is lowered, which in turn drives the pull rope 45 to transmit, thereby pulling the clamping plate 3 to rise, and further rotates through the engagement of the gear 55 and the tooth plate 56, and then drives the two nuts 52 to move closer, and finally the pressure plate 54 clamps and fixes the straw, and the fixed straw is pulled out and cleaned as the clamping plate 3 rises, and the clamping plate 3 is driven to rise by stepping on the transmission mechanism 4. When the clamping plate 3 rises, it drives the clamping mechanism 5 to clamp the straw, and the straw is quickly pulled out. While increasing the straw pulling speed, the operating steps of the staff are reduced at the same time, and the straw pulling efficiency is greatly improved.

[0035] The transmission mechanism 4 drives the clamping plate 3 through the lever principle, so that the staff can completely pull out the straw with less effort. This driving method greatly reduces the workload of the staff.
