However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] likeFigures 1-6 As shown, this utility model provides an auxiliary device for improving saline-alkali land, including a liquid storage tank 100. Four wheels 200 are installed at the four corners of the liquid storage tank 100. A mounting frame 300 is provided at the bottom of the liquid storage tank 100. Electric push rods 400 for driving the mounting frame 300 to move up or down are fixedly installed on the front and rear of the liquid storage tank 100. Evenly distributed insertion rods 500 are provided on the mounting frame 300, and a spraying assembly 600 is installed inside each insertion rod 500. A pressure pump 700 is installed inside the storage tank 100. The pressure pump 700 pumps the liquid medicine in the storage tank 100 and sprays it onto the soil through the spraying assembly 600. The mounting frame 300 is equipped with a drive assembly 800 and several drilling assemblies 900 surrounding the outside of the insertion rod 500. The drive assembly 800 drives the drilling assemblies 900 to rotate. The electric push rod 400 can also be replaced with a cylinder or hydraulic cylinder to achieve the purpose of raising and lowering the mounting frame 300. This will not be described in detail here.

[0027] In this embodiment, the mounting frame 300 includes a top plate 301 and a bottom plate 302. A plurality of columns 303 are fixedly connected between the top plate 301 and the bottom plate 302. The length of the bottom plate 302 is greater than the length of the top plate 301. Ear plates 304 are fixedly connected to the side of the top plate 301. The movable ends of the electric push rod 400 are fixedly connected to the bottom plate 302.

[0028] In this embodiment, the drilling assembly 900 includes a ring 901 rotatably mounted on the base plate 302. Two extension rods 902 are fixedly connected to the bottom of the ring 901. A spiral drill bit 903 sleeved on the outside of the insertion rod 500 is fixedly connected between the bottom ends of the two extension rods 902. After the ring 901 rotates, the spiral drill bit 903 can be driven to rotate through the extension rods 902, which facilitates the insertion rod 500 to penetrate the soil.

[0029] In this embodiment, the drive assembly 800 includes a motor 801 fixedly mounted on the ear plate 304. The output shaft of the motor 801 passes through the ear plate 304 and is fixedly sleeved with a drive wheel 802. Driven wheels 803 are fixedly sleeved on the outer walls of several rings 901. A tension wheel 804 is rotatably provided on the top of the base plate 302. A transmission belt 805 is provided between the drive wheel 802, the driven wheel 803, and the tension wheel 804. The motor 801 drives the drive wheel 802 to rotate, and the transmission belt 805 drives the drive wheel 802 to rotate. The function of the drive wheel 802 and the tension wheel 804 is to drive the driven wheel 803 to rotate, thereby realizing the rotation of the ring 901. The drive wheel 802, driven wheel 803, tension wheel 804 and transmission belt 805 can be one of belt drive system or chain drive system, and the wrap angle meets the specifications. The number of tension wheels 804 is rotated according to the actual situation to ensure that the transmission conditions for the drive wheel 802 to drive the driven wheel 803 to rotate are met. Since the means used are conventional and publicly available, they will not be described in detail here.

[0030] In this embodiment, the spraying assembly 600 includes a spraying pipe 601, with a spraying head 602 threadedly connected to the end of the spraying pipe 601. The end of the spraying head 602 away from the spraying pipe 601 can pass through the insertion rod 500 and be fixedly connected to a first filter screen 603. A second filter screen 604 is provided between the spraying head 602 and the spraying pipe 601. When the spraying head 602 is threadedly connected to the spraying pipe 601, the second filter screen 604 is clamped. The first filter screen 603 and the second filter screen 604 are used for filtration to prevent soil from clogging the spraying pipe 601 and the spraying head 602, thus ensuring the spraying operation.

[0031] In this embodiment, a water collection chamber 701 is fixedly installed on the top of the insertion rod 500. A flexible hose 702 connects the water collection chamber 701 and the spray pipe 601. The output end of the pressure pump 700 is connected to a diversion pipe 703 installed in the storage tank 100. Several ports of the diversion pipe 703 are connected to the corresponding water collection chamber 701 by a telescopic corrugated pipe 704. The pressure pump 700 pumps the liquid medicine in the storage tank 100 out and enters the water collection chamber 701 through the diversion pipe 703 and the corrugated pipe. Then, it enters the flexible hose 702 from the water collection chamber 701 and finally enters the spray pipe 601 and is sprayed out by the spray head 602.

[0032] In this embodiment, a screw 605 is rotatably mounted on the water collection chamber 701 via a sealed bearing. The bottom end of the screw 605 extends into the insert rod 500 and is threadedly connected to a moving block 606. A connecting rod 607 is hinged between the moving block 606 and the spray pipe 601. A handle 608 is fixedly connected to the top end of the screw 605. The screw 605 can be rotated by the handle 608. The threaded drive causes the moving block 606 to drive the connecting rod 607 to push the spray pipe 601 to move. The spray pipe 601 drives the spray head 602 to move out of the insert rod 500, which can separate the spray head 602 from the spray pipe 601. Then, the first filter screen 603 and the second filter screen 604 can be cleaned.

[0033] In this embodiment, a limiting rod 609 is fixedly connected to the inner wall of the insertion rod 500, and a limiting block 6010 is slidably provided on the limiting rod 609. The top of the limiting block 6010 is fixedly connected to the spray pipe 601, and the spray pipe 601 is limited by the cooperation of the limiting rod 609 and the limiting block 6010.

[0034] How to use and how to work this device:

[0035] When the device is in use, the electric push rod 400 and the motor 801 work synchronously. The electric push rod 400 drives the mounting frame 300, causing the insertion rod 500 and the auger drill bit 903 to descend. At the same time, the motor 801 drives the drive wheel 802 to rotate. The driven wheel 803, tension wheel 804 and transmission belt 805 cause several driven wheels 803 to drive the ring 901 to rotate. After the ring 901 rotates, it can drive the auger drill bit 903 to rotate through the extension rod 902, which facilitates the insertion rod 500 into the soil. The auger drill bit 903 breaks up the soil. At the same time, the pressure pump 700 pumps out the liquid medicine, which enters the spray pipe 601 through the diversion pipe 703, corrugated pipe 704, water collection chamber 701 and hose 702. Finally, it is sprayed out by the spray head 602. The medicine can mix with the broken soil. As the insertion rod 500 goes deeper, the medicine is sprayed into the deep soil, which can effectively improve the soil quality.

[0036] When the spray head 602 is spraying, the first filter 603 and the second filter 604 work together to prevent soil from clogging the spray pipe 601 and the spray head 602, ensuring the spraying operation is carried out. After the spraying operation is completed or during periodic testing, the screw 605 can be rotated by the throttle 608. The screw drive causes the moving block 606 to drive the connecting rod 607 to move the spray pipe 601. The spray pipe 601 moves the spray head 602 out of the insert rod 500, separating the spray head 602 from the spray pipe 601. Then the first filter 603 and the second filter 604 can be cleaned or replaced to ensure that clogging does not occur and affect the spraying of the pesticide.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
