Description

Technical Field

[0001] The invention relates to the technical field of equipment for improving desertified land, and in particular to a mobile uniform and efficient spraying device. Background Art

[0002] Desertified land is primarily composed of sandy soils. Existing desertified farmland, located in a fragile ecological zone, is cultivated extensively, resulting in low yields. Wind erosion is severe during the winter, spring, and early summer seasons. Wind erosion causes a significant loss of organic matter and nutrients from sandy farmland, leading to a serious decline in soil fertility. Establishing shelterbelts for farmland is ineffective, reducing farmers' arable land. These efforts are also costly and time-consuming. Therefore, conserving moisture and heat in desertified farmland is a key technical approach to addressing desertification. Existing technologies address this by spraying a crusting slurry onto the surface of the desertified land. This slurry typically contains a certain proportion of clay, organic matter, and minerals. This slurry improves the extremely poor and loose soil structure of the desertified land, increasing its water-holding capacity and nutrient reserves. This crust slows surface water evaporation and reduces the rate of rainwater infiltration during rainfall, preventing rapid water seepage and loss, thus retaining more moisture for plant growth.

[0003] After searching, the patent with announcement number CN220005387U is an irrigation device for desertified soil remediation. A mixing barrel is fixedly installed on the vehicle body. The mixing barrel is intermittently engaged between the half gear and the rack in the transmission mechanism, so that the extrusion rod drives the vertical rod to move left and right to continuously squeeze the nozzle, and finally the nozzle swings left and right to make the spraying range wider. However, in the actual spraying process, since the clay slurry is easy to settle, it needs to be stirred in real time, and the single stirring structure reduces the mixing efficiency. In addition, the movement speed of the vehicle body is not synchronized with the spraying, which will cause uneven spraying. At the same time, there are generally strong winds in desertified areas, which will blow away the sprayed slurry, and the spraying position cannot be guaranteed, affecting subsequent planting.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, a mobile uniform and efficient spraying device includes a mobile body 1 for realizing the movement of the entire device and improving the spraying efficiency. The specific size of the mobile body 1 can be selected according to the actual area of the desertified land.

[0023] In order to improve the mixing efficiency, the present embodiment is provided with a composite stirring mechanism 2 in the mixing box 11 of the mobile body 1. The composite stirring mechanism 2 includes a rotary stirring mechanism 21 and a reciprocating stirring mechanism 22. The rotary stirring mechanism 21 is connected to the rotary stirring mechanism 22. The rotary stirring mechanism 21 includes a stirring rotating shaft 211. The stirring rotating shaft 211 is installed in the mixing box 11 and is provided with a plurality of first stirring plates 212 on the circumferential side. The stirring rotating shaft 211 is connected to a rotary drive motor 213 outside the mixing box 11 to provide a horizontal rotation stirring function. Figure 2-Figure 3 As shown, in Figure 2 Only one reciprocating stirring mechanism 22 is shown in FIG. 2 , and two reciprocating stirring mechanisms 22 are provided and are provided on both sides of the stirring rotating shaft 211, as shown in FIG. Figure 4 As shown, the reciprocating stirring mechanism 22 includes a driving rotating shaft 221, which is mounted on the mixing box 11, and a variable diameter spiral driving track 222 is provided on the circumferential side of the driving rotating shaft 221 in the mixing box 11 (the spiral radius gradually decreases along the inner side of the mixing box 11), and a limiting roller 223 is provided on the variable diameter spiral driving track 222, which is mounted on an L-shaped mounting plate 224, and a plurality of linearly distributed second stirring plates 225 are mounted on the horizontal plate of the L-shaped mounting plate 224, and a first guide sleeve 226 is sleeved on the vertical plate of the L-shaped mounting plate 224, and a guide plate 227 is connected to the outside of the first guide sleeve 226, and the guide plate 227 is inserted in the second guide sleeve 228 of the mobile body 1, and the driving rotating shaft 221 outside the mixing box 11 is connected to the rotary driving motor 213 through a gear chain. A guide groove 13 is provided on the side of the mixing box 11, and a guide roller 229 on the side of the second stirring plate 225 is arranged in the guide groove 13 to improve the support strength of the second stirring plate 225. The driving rotary shaft 221 rotates forward and reversely under the drive of the rotary drive motor 213, causing the limiting roller 223 to reciprocate along the variable diameter spiral drive track 222. As the spiral radius gradually decreases along the inner side of the mixing box 11, the L-shaped mounting plate 224 moves downward during the forward movement and synchronously moves backward and upward, thereby achieving reciprocating movement of the slurry in the mixing box 11, providing stirring in the front-back and up-down directions. Combined with the rotary stirring mechanism 21, three-dimensional stirring is achieved, improving stirring efficiency.

[0024] like Figure 5As shown, the outer end of the first stirring plate 212 and the bottom end of the second stirring plate 225 are both provided with a receiving groove, which is connected to one side of the telescopic plate 24 via an adjustment spring 23, ensuring that the first stirring plate 212 and the second stirring plate 225 can contact the bottom of the mixing box 11. The other side of the telescopic plate 24 is semicircular, which allows the telescopic plate 24 on the first stirring plate 212 to move more smoothly when contacting the bottom of the mixing box 11. The first stirring plate 212 and the second stirring plate 225 have the same structure, and only differ in the movement direction, installation position and size, which will not be repeated here.

[0025] The tail of the mixing box 11 is provided with a spraying mechanism 4, such as Figure 6 As shown, the spraying mechanism 4 includes a fixed plate 41 installed at the tail of the mixing box 11, a spraying pump 42 is installed on the fixed plate 41, the water inlet pipe of the spraying pump 42 is connected to the mixing box 11, and the water outlet pipe of the spraying pump 42 is connected to the spraying pipe 43, which is slidably set on the fixed plate 41.

[0026] The spraying mechanism 4 is connected to the mobile drive motor 12 of the mobile body 1 through the transmission mechanism 5. The transmission mechanism 5 includes a transmission clutch 51 connected to the mobile drive motor 12. The output shaft of the transmission clutch 51 is connected to a driving sprocket 52. The driving sprocket 52 is connected to a driven sprocket 53 through a transmission chain. The driven sprocket 53 is connected to the rotating shaft of the spray pump 42. A first transmission gear 54 is installed on the driven sprocket 53. The first transmission gear 54 is meshed with a second transmission gear 56 at one end of a drive shaft 55. The drive shaft 55 is installed on the fixed On the fixed plate 41, a wave groove 57 is opened on the circumferential side of the driving shaft 55, and a driving column 58 is arranged in the wave groove 57. The driving column 58 is connected to the spray pipe 43. The transmission mechanism 5 realizes transmission connection and transmission separation with the mobile drive motor 12 through the clutch. When in transmission connection, the mobile drive motor 12 drives the mobile body 1 to move, and at the same time, the spray pump 42 adjusts the rotation speed according to the moving speed, so that the spraying is more uniform. When in transmission separation, the mobile drive motor 12 only drives the mobile body 1 to move, so that the spray pump 42 is no longer driven when there is no slurry.

[0027] In order to be suitable for strong winds, foldable windproof mechanisms 6 are provided on both sides of the rear end of the mixing box 11 (at Figure 1 Only one foldable windproof mechanism 6 is shown in FIG. Figure 3One is folded and the other is unfolded, and one or two are used according to the actual wind direction). The foldable windproof mechanism 6 includes a hinge sleeve 61 installed on the outside of the mixing box 11, and a hinge shaft 61 is rotatably connected in the hinge sleeve 61. The hinge shaft 61 is connected to a U-shaped mounting plate 63. A positioning through hole is provided on the U-shaped mounting plate 63, and a positioning pin 64 is provided in the positioning through hole. The hinge sleeve 61 is provided with a positioning groove arranged opposite to the positioning through hole. The U-shaped mounting plate 63 is rotatably connected to one end of several windshields 65 arranged in parallel. The number of windshields 65 is set according to specific shielding needs. The more the number, the better the windshield effect. The other ends of several windshields 65 are rotatably connected to the linear mounting plate 66. A supporting roller 67 is installed at the bottom of the linear mounting plate 66. A hanging plate 68 is provided on the top of the linear mounting plate 66. The hanging plate 68 is connected to the guardrail of the mixing box 11 through a spring buckle.

[0028] In the case of strong winds, the linear mounting plate 66 is removed from the guardrail of the mixing box 11 and rotated 180° so that the positioning hole and the positioning slot are arranged vertically opposite to each other. The positioning pin 64 is inserted into the positioning slot through the positioning hole so that the U-shaped mounting plate 63 maintains the current angle and does not swing to both sides. The supporting roller 67 is placed on the ground, and the windshield plates 65 arranged in parallel on both sides form a windshield structure to ensure the spraying accuracy of the spraying mechanism 4 in the middle and reduce the impact of strong winds on spraying.

[0029] In order to facilitate the mixing of slurry, a water inlet connecting pipe 14 is provided on the front support frame of the mixing box 11, and a flow meter is provided on the water inlet connecting pipe 14. At least one water outlet valve 15 is provided at the relative position between the front support frame and the mixing box 11. The water supply pipe can be directly installed on the water inlet connecting pipe 14. After the water supply pipe supplies water, the water entering the mixing box 11 is measured, and solid materials are added at the same time. The rotary drive motor 213 is started to achieve stirring while adding materials. When the measured water reaches the mixing concentration requirement, the water outlet valve 15 is closed manually or automatically. The automatic closing of the water outlet valve 15 is connected to the flow meter and the water outlet valve 15 through the existing controller to realize automatic control. Controlling the corresponding valve body through the flow meter data is an existing technology and will not be described in detail here.
