DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example: Refer to Figures 1 to 5 A soil turning device for efficient agricultural production comprises a fixed frame 1, a main screw 2 is rotatably mounted on one end of the fixed frame 1, a slave screw 3 is rotatably mounted on the other end of the fixed frame 1, the main screw 2 is transmission-connected with the slave screw 3, an adjusting plate 4 is threadedly connected to the main screw 2 and the slave screw 3, connecting columns 5 are fixedly mounted on the opposite inner sides of the two adjusting plates 4, a rotating shaft 6 is fixedly mounted on the connecting columns 5, a plurality of crushing wheels 7 are fixedly mounted on the rotating shaft 6, and a limiting mechanism is arranged on the inner wall of the fixed frame 1; when turning the soil, when it is necessary to adjust the height of the crushing wheel 7 according to the soil conditions, the main screw 2 is rotated, and the main screw 2 is connected to the main screw 2 through the transmission connection The slave screw 3 is then driven to rotate, and the two adjusting plates 4 drive the connecting column 5 to move up and down. The connecting column 5 drives the multiple crushing wheels 7 to move up and down through the rotating shaft 6 until the multiple crushing wheels 7 are adjusted to a suitable height. After the crushing wheels 7 are adjusted to a suitable position, the adjusting plate 4 is limited by the limiting mechanism to further prevent the crushing wheels 7 from sliding upward when crushing the soil. The height of the crushing wheel 7 is adjusted according to the soil conditions through the main screw 2 and the slave screw 3, thereby improving the practicability of the crushing wheel 7, so that the crushing wheel 7 can turn over the soil with different requirements, thereby ensuring the turning efficiency and quality of the crushing wheel 7.

[0024] Specifically, a bulldozer frame 8 is fixedly installed on the fixed frame 1, and a plurality of through grooves 9 are opened on the bulldozer frame 8. A plurality of tilling shovels 10 are fixedly installed on the bulldozer frame 8. When tilling the soil, the soil is firstly crushed by the tilling shovel 10, and then further crushed by the crushing wheel 7. The plurality of through grooves 9 can allow the soil turned up by the tilling shovel 10 to fall back onto the ground to prevent it from being pushed forward by the fixed frame 1.

[0025] Specifically, the limiting mechanism includes a plurality of slide grooves 11 provided on the fixed frame 1, in which a slide rod 12 is slidably installed, a pull ring 13 is fixedly installed at one end of the slide rod 12, and a limit block 14 is fixedly installed at the other end of the slide rod 12, the top of the limit block 14 is arranged in an arc shape, and a spring 15 is fixedly installed on the limit block 14, the spring 15 is sleeved on the outer side of the slide rod 12, and the other end of the spring 15 is fixedly connected to the fixed frame 1; when the adjusting plate 4 moves downward, when the adjusting plate 4 contacts the limit block 14, the adjusting plate 4 squeezes the limit block 14, so that the limit block 14 and the slide rod 12 slide in the direction of the pull ring 13, and the spring 15 is also compressed. After the adjusting plate 4 moves downward, the elastic force of the spring 15 resets the limit block 14 and the slide rod 12, thereby preventing the adjusting plate 4 from moving upward. If the soil turning operation is completed, the limit of the adjusting plate 4 can be released by pulling the pull ring 13 while rotating the main screw 2 to adjust the position of the adjusting plate 4.

[0026] Furthermore, a limit rod 16 is fixedly installed at the top and bottom ends of the slide rod 12, and a limit groove 17 slidably connected to the limit rod 16 is opened in the slide groove 11; when the slide rod 12 slides in the slide groove 11, the limit rod 16 also slides in the limit groove 17, and the limit rod 16 and the limit groove 17 prevent the slide rod 12 from rotating in the slide groove 11, thereby preventing its rotation from affecting the limiting of the adjustment plate 4 by the limit block 14.

[0027] Furthermore, a mounting frame 19 is fixedly installed on one side of the fixed frame 1 close to the slide groove 11, and two connecting rods 20 are fixedly installed on the mounting frame 19. The connecting rods 20 are provided with mounting holes 21, and a support rod 22 is fixedly installed between the fixed frame 1 and the mounting frame 19. When in use, the device is installed on the machine through the connecting rods 20 and the mounting holes 21, and the machine pushes the device, and the support rods 22 support the mounting frame 19.

[0028] Furthermore, a turning handle 23 is fixedly installed on the top of the main screw 2, and a limiting ring 18 is fixedly installed on the top of the slave screw 3; the turning handle 23 makes it easier for the operator to rotate the main screw 2, and the limiting ring 18 supports the slave screw 3 to prevent the slave screw 3 from separating from the fixed frame 1 when rotating.

[0029] The working principle of this device is as follows:

[0030] When turning the soil, when it is necessary to adjust the height of the crushing wheel 7 according to the soil conditions, the main screw 2 is rotated by the turning handle 23. The main screw 2 drives the slave screw 3 to rotate through the transmission connection, thereby making the two adjusting plates 4 drive the connecting column 5 to move up and down, and the connecting column 5 drives the multiple crushing wheels 7 to move up and down through the rotating shaft 6 until the multiple crushing wheels 7 are adjusted to a suitable height. When the adjusting plate 4 moves down to contact with the limit block 14, the adjusting plate 4 squeezes the limit block 14, so that the limit block 14 and the slide bar 12 slide in the direction of the pull ring 13, and the spring 15 is also compressed. After the adjusting plate 4 moves down, the elastic force of the spring 15 makes the limit block 14 and the slide bar 12 reset, thereby making the adjusting plate 4 unable to move upward, further preventing the crushing wheel 7 from sliding upward when crushing the soil, and adjusting the height of the crushing wheel 7 according to the soil conditions through the main screw 2 and the slave screw 3, thereby improving the practicability of the crushing wheel 7, so that the crushing wheel 7 can turn the soil for soil with different requirements, thereby ensuring the turning efficiency and turning quality of the crushing wheel 7.
