Description

Technical Field

[0001] The utility model relates to the technical field of weeding devices, and particularly relates to an agricultural field weeding device. Background Art

[0002] Summer is the season when crops grow rapidly. At the same time, it is also the season when weeds grow in profusion and pests breed. They will compete with crops for sunlight, growing space, nutrients, etc., thus affecting the normal growth of crops. In order to enable crops to grow normally, weeding is required, so an agricultural field weeding device will be used;

[0003] For this reason, the patent with the publication number CN218570782U discloses a field weeding device, belonging to the technical field of weeding devices. It mainly includes a frame, harrow teeth, and claw teeth. The frame includes a horizontal cross beam and fixing rods connecting and fixing the cross beam. The harrow teeth are vertically and evenly installed at the bottom of the cross beam, and the claw teeth are installed behind the harrow teeth. The frame is connected to an agricultural tractor through a hydraulic cylinder and a connecting rod; this weeding device has high weeding efficiency and good effect; the harrow teeth can crush the soil blocks dug by plowing, loosen the field soil, and make the roots of weeds loose in the soil. At the same time, the claw teeth can carry the weeds. As the tractor runs, when there are more weeds, the weeds may break away from the claw teeth and pile up on the ground in a heap, and then can be removed by manual or equipment, which is beneficial to reducing labor intensity and improving work efficiency;

[0004] Although the above-mentioned field weeding device can crush the soil blocks dug by plowing through the harrow teeth, loosen the field soil, and make the roots of weeds loose in the soil, and at the same time the claw teeth can carry the weeds when in use, it is not convenient to adjust the position during use, not convenient to adjust the spacing of the weeding cutter disc, not suitable for crops with different gaps, and is easy to accidentally injure the crops, resulting in low applicability when in use. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an agricultural field weeding device to solve the defect that the existing agricultural field weeding device is not convenient to adjust the position.

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 of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0028] Please refer to Figures 1 - 5, a kind of agricultural field weeding device provided by the utility model includes a support base 1 and a connection base 2. At both ends inside the support base 1, walking wheels 5 penetrate through. Above the support base 1, a moving structure 4 is arranged. The moving structure 4 includes a first hinge seat 401, a hydraulic telescopic rod 402 and a second hinge seat 403. The hydraulic telescopic rod 402 is arranged above the support base 1. One end of the hydraulic telescopic rod 402 is hinged to the first hinge seat 401, and the other end of the hydraulic telescopic rod 402 is hinged to the second hinge seat 403. The bottom end of the first hinge seat 401 is fixedly connected to the top end of the connection base 2, and the bottom end of the second hinge seat 403 is fixedly connected to the top end of the fixed base 7. Both ends of the walking wheel 5 extend into the support base 1 and form a rotating structure with the walking wheel 5. The weeding cutter discs 11 are symmetrically distributed at both ends of the bottom of the fixed rod 10.

[0029] Refer to Figure 1 and Figure 2 As shown in the figure, start the hydraulic telescopic rod 402. The hydraulic telescopic rod 402 drives the second hinge seat 403 to move. The second hinge seat 403 drives the fixed base 7 to move. The fixed base 7 rotates inside the support base 1 through the third hinge seat 6, thereby changing the angle of the fixed base 7. The fixed base 7 drives the weeding cutter disc 11 to move through the fixed rod 10, so that the weeding cutter disc 11 is separated from the soil, making it convenient for storage when not in use.

[0030] One side of the support base 1 is fixedly connected with a connection base 2. On the other side inside the support base 1, third hinge seats 6 are evenly hinged. At the end of the connection base 2 away from the support base 1, a fixing structure 3 is arranged. The fixing structure 3 includes an installation frame 301, an activity groove 302, a latch 303, a return spring 304, a pull ring 305 and a connecting rod 306. The installation frame 301 is fixed at one end of the connection base 2. Activity grooves 302 are opened on both sides inside the installation frame 301. Latches 303 are arranged inside the activity grooves 302. One ends of the latches 303 are fixedly connected with connecting rods 306. One ends of the connecting rods 306 extend to the outside of the installation frame 301 and are fixedly connected with pull rings 305. Return springs 304 are sleeved on the outer sides of the connecting rods 306 inside the activity grooves 302. The connecting rods 306 and the latches 303 form a telescopic structure through the return springs 304. The latches 303 are symmetrically distributed on both sides inside the installation frame 301.

[0031] Refer to Figure 3 and Figure 5As shown in the figure, pull the pull ring 305. The pull ring 305 drives the pin 303 to move into the interior of the movable slot 302 through the connecting rod 306, and insert one end of the vehicle body mounting part into the interior of the mounting frame 301. At this time, release the pull ring 305. Under the elastic force of the return spring 304, the pin 303 moves into the interior of the vehicle body mounting part, thereby fixing the mounting frame 301 and the vehicle body mounting part to each other. When the vehicle body is used for traction and the vehicle body drives the mounting frame 301 to move, the mounting frame 301 drives the traveling wheels 5 to move through the connecting seat 2, and the traveling wheels 5 drive the weeding cutter disc 11 to carry out weeding through the fixing rod 10.

[0032] A fixed seat 7 is fixed to one end of the third hinge seat 6 away from the support seat 1. One side inside the fixed seat 7 is penetrated by an installation slot 8. An adjusting structure 9 is evenly arranged inside the installation slot 8. The adjusting structure 9 includes a fixing plate 901, a hoop 902 and a fixing nut 903. The hoops 902 penetrate evenly inside the installation slot 8. Fixing plates 901 are sleeved on the outer sides of the hoops 902. Fixing nuts 903 are sleeved on the outer walls of the hoops 902 on one side of the fixing plate 901. The fixing plate 901 and the hoop 902 form a sliding structure, and the fixing nut 903 and the hoop 902 are designed to be in threaded connection. One side of the fixing plate 901 is fixedly connected to one end of the fixing rod 10. A fixing rod 10 is fixed to one side of the adjusting structure 9. Both ends of the bottom of the fixing rod 10 are rotatably connected to the weeding cutter disc 11.

[0033] Referring to Figure 1 and Figure 4 As shown in the figure, rotate the fixing nut 903 to separate the fixing nut 903 from the hoop 902, move the fixing plate 901 and the hoop 902. The fixing plate 901 drives the weeding cutter disc 11 to move through the fixing rod 10. After moving to a suitable position, sleeve the fixing nut 903 on the outer side of the hoop 902 to fix the fixing nut 903 and the hoop 902 to each other, thereby fixing the fixing plate 901 and the hoop 902 to each other, and thus changing the distance between the weeding cutter discs 11.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
