Description

Technical Field

[0001] This invention relates to the field of soil conditioner spraying technology, and in particular to a soil conditioner spraying device for supplementing arable land. Background Technology

[0002] To maintain a balance in the total amount of arable land and safeguard food security, the implementation of arable land replenishment measures has become crucial. Arable land replenishment mainly refers to the process of converting abandoned or other unused land into arable land within a region. This includes land consolidation and land reclamation, aiming to increase the arable land area within the region, thereby compensating for arable land losses caused by other construction or natural factors. This replenishment includes not only quantitative increases but also qualitative improvements, ensuring that the replenished arable land can be truly used for agricultural production. It is an important means of safeguarding national food security and achieving the sustainable use of land resources.

[0003] The implementation of farmland replenishment includes multiple approaches. For example, land consolidation projects can be used to restore abandoned or damaged land to meet the standards for arable land; land reclamation projects can be used to restore abandoned industrial and mining land or other construction land to arable land; in addition, the yield and quality of existing arable land can be improved by promoting advanced agricultural technologies and management measures. However, replenishing arable land also faces some problems: 1) The soil for replenishing arable land usually comes from deep subsoil, abandoned industrial and mining land, sandy land, tidal flats, etc., with extremely low organic matter content, or even almost zero, and poor water and fertilizer retention capacity; 2) The soil may be too compacted and hard (such as industrial and mining land) or too loose and sandy (such as sandy land). The former is impermeable to water and air, and the roots cannot penetrate deep; the latter is not good at retaining water and fertilizer, and nutrients are lost with water; 3) The chemical properties are unbalanced, and there is a barrier layer, such as acid-base imbalance, excessive salt content, lack of nutrients, or heavy metal pollution; 4) The microbial community is lacking, and the soil lacks "vitality". Therefore, in order to quickly compensate for inherent soil defects and ensure high crop yields, it is necessary to spray nutrient-based soil conditioners on crop leaves during the crop growth period.

[0004] We know that, compared to the upper surface of a leaf, the veins on the lower surface are more prominent and rougher, making it easier for droplets to adhere and remain. Furthermore, the lower surface of the leaf has more stomata and a thinner cuticle, which is more conducive to the penetration and absorption of plant amendments. However, for crops with longer leaves, such as corn, the leaf tips naturally curve and droop, making it difficult to spray amendments onto the lower surface of the leaves during application. This affects the absorption of the amendments and reduces crop yield. Summary of the Invention

[0005] This invention provides a soil conditioner spraying device for supplementing arable land, which can solve the problem in the prior art that it is often difficult to spray the conditioner onto the back of the leaves during the spraying process, which affects the absorption effect of the conditioner and reduces crop yield.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a soil conditioner spraying device for supplementing arable land, comprising: Vehicle body; A spraying assembly, comprising: a nozzle for spraying an amendment solution onto the front and back of crop leaves; and a lifting mechanism mounted on the vehicle body for driving the nozzle to perform reciprocating lifting motion. A reversing assembly includes: a mounting plate fixedly connected to a lifting mechanism; a guide cylinder disposed on the mounting plate; a sliding rod slidably connected to the inner side of the guide cylinder; an elastic element disposed between the sliding rod and the guide cylinder; a driving gear and a driven gear rotatably connected to the mounting plate, the nozzle being fixedly connected to the driven gear, and the driving gear meshing with the driven gear; a first connecting rod, one end of which is hinged to the sliding rod; a second connecting rod, one end of which is hinged to the first connecting rod, and the other end of which is fixedly connected to the driving gear; an upper limit rod and a lower limit rod, the upper limit rod being located above the second connecting rod, and the lower limit rod being located below the second connecting rod.

[0007] Preferably, the nozzle is provided with a connecting rod, and the end of the connecting rod is provided with a long rod.

[0008] Preferably, the long rod is inclined, and a current collection box is provided at the lower end of the long rod.

[0009] Preferably, the collection box is connected to a return pipe that is connected to the spraying assembly.

[0010] Preferably, a filter screen is provided at the connection end between the collection box and the long rod.

[0011] Preferably, the reversing assembly further includes an upper limit pin and a lower limit pin, which are fixedly connected to the mounting plate, and the second connecting rod is located between the upper limit pin and the lower limit pin.

[0012] Preferably, the lifting mechanism includes: a guide groove disposed on the vehicle body; a lead screw nut slidably connected inside the guide groove; a ball screw rotatably connected to the inner side of the guide groove, and the lead screw nut threadedly connected to the ball screw; and a drive unit, the output end of which is fixedly connected to the ball screw.

[0013] Preferably, an extension plate is provided at the upper end of the guide groove, and the upper limit rod is threadedly connected to the extension plate.

[0014] Preferably, the spraying assembly further includes a liquid storage container and a water pump. The liquid storage container is mounted on the vehicle body and is used to store the modifier solution. The inlet end of the water pump is connected to the liquid storage container, and the outlet end of the water pump is connected to the spray nozzle.

[0015] Compared to existing technologies, this invention utilizes a vehicle body, nozzle, lifting mechanism, mounting plate, guide cylinder, slide bar, elastic element, driving gear, driven gear, first connecting rod, second connecting rod, upper limit rod, and lower limit rod in a coordinated configuration. The lifting mechanism drives the nozzle and mounting plate to reciprocate upward and downward movements. During the upward movement of the nozzle and mounting plate, the nozzle tilts upward, spraying the amendment solution onto the back of the crop leaves. When the second connecting rod contacts the upper limit rod, it experiences a downward compressive force from the upper limit rod. This force drives the driving gear to rotate, which in turn drives the nozzle to rotate via the driven gear, causing the nozzle to face upward. The first link tilts downwards, while the second link, through the first link, presses the slide bar into the guide cylinder, compressing the elastic element. After the first and second links change direction, the slide bar resets under the elastic potential energy of the elastic element. The lifting mechanism drives the nozzle and mounting plate to descend, and the downward-tilting nozzle sprays the amendment solution onto the front of the crop leaves. When the second link contacts the lower limit rod, the second link is subjected to an upward squeezing force from the lower limit rod, and the nozzle changes direction again. This cycle repeats, coordinating with the movement of the vehicle body, to spray the amendment solution onto both sides of all crop leaves, improving the crop's absorption of the amendment and increasing crop yield.

[0016] Compared to existing technologies, this invention, through the coordinated arrangement of a connecting rod and a long rod, causes the long rod to move synchronously when the nozzle is raised, lowered, or tilted. During the nozzle's ascent, the long rod contacts the back of the blades, flipping the drooping blades upwards. This facilitates the nozzle spraying the amendment solution onto the back of the blades, avoiding blind spots and thus improving the crop's absorption of the amendment, thereby increasing crop yield.

They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1 to 6 As shown, a soil conditioner spraying device for supplementing arable land includes: Vehicle body 1; The spraying assembly includes: a nozzle 3, which is used to spray the amendment solution onto the front and back of the crop leaves; and a lifting mechanism, which is mounted on the vehicle body 1 and is used to drive the nozzle 3 to perform reciprocating lifting motion. The reversing assembly includes: a mounting plate 5, which is fixedly connected to the lifting mechanism; a guide cylinder 6, which is disposed on the mounting plate 5; a slide rod 7, which is slidably connected to the inner side of the guide cylinder 6; an elastic element 8, which is disposed between the slide rod 7 and the guide cylinder 6, and the elastic element 8 is a spring or a metal sheet; a driving gear 9 and a driven gear 10, which are rotatably connected to the mounting plate 5 respectively, and the nozzle 3 is fixedly connected to the driven gear 10, with the driving gear 9 and the driven gear 10 meshing; a first connecting rod 11, one end of which is hinged to the slide rod 7; a second connecting rod 12, one end of which is hinged to the first connecting rod 11, and the other end of which is fixedly connected to the driving gear 9; an upper limit rod 13 and a lower limit rod 14, with the upper limit rod 13 located above the second connecting rod 12 and the lower limit rod 14 located below the second connecting rod 12.

[0021] In practical use, the lifting mechanism drives the nozzle 3 and mounting plate 5 to reciprocate upward and downward movements. During the upward movement, the nozzle 3 tilts upward, spraying the amendment solution onto the back of the crop leaves. When the second connecting rod 12 contacts the upper limit rod 13, the second connecting rod 12 is subjected to a downward squeezing force from the upper limit rod 13. The second connecting rod 12 drives the drive gear 9 to rotate, which in turn drives the nozzle 3 to rotate via the driven gear 10, causing the nozzle 3 to tilt downward. Simultaneously, the second connecting rod 12 guides the first connecting rod 11... Inside the cylinder 6, the sliding rod 7 is squeezed, and the elastic element 8 is compressed. After the first connecting rod 11 and the second connecting rod 12 change direction, the sliding rod 7 returns to its original position under the elastic potential energy of the elastic element 8. The lifting mechanism drives the nozzle 3 and the mounting plate 5 to descend. The downward-tilting nozzle 3 sprays the improver solution onto the front of the crop leaves. When the second connecting rod 12 contacts the lower limit rod 14, the second connecting rod 12 is subjected to the upward squeezing force of the lower limit rod 14. The nozzle 3 changes direction again, and so on. In coordination with the movement of the vehicle body 1, the improver solution is sprayed onto the front and back of all crop leaves.

[0022] In order to improve the absorption of the amendment by crops, preferably, the nozzle 3 is provided with a connecting rod 17, and the end of the connecting rod 17 is provided with a long rod 18.

[0023] Specifically, when the nozzle 3 is raised, lowered, and rotated, the connecting rod 17 drives the long rod 18 to move synchronously. During the raising of the nozzle 3, the long rod 18 contacts the back of the blade, flipping the drooping blade upward, so that the nozzle 3 can spray the amendment solution on the back of the blade, avoiding spray blind spots, thereby improving the crop's absorption of the amendment and increasing crop yield.

[0024] To save on additives, preferably, the long rod 18 is inclined, and a collection box 19 is provided at the lower end of the long rod 18. The collection box 19 is connected to a return pipe 21 that is connected to the spraying assembly. A filter screen 20 is provided at the connection end between the collection box 19 and the long rod 18.

[0025] Specifically, during the spraying of the improver solution, some of the improver solution will inevitably be sprayed onto the long rod 18, and the improver droplets sprayed on the blades will also accumulate along the blades. Since the long rod 18 is in contact with the blades, these accumulated droplets will be guided onto the long rod 18, and then filtered by the filter screen 20 and temporarily stored in the collector box 19. When the collector box 19 rises above the storage container 2, the improver solution in the collector box 19 will flow back to the storage container 2 through the return pipe 21 for secondary use.

[0026] In order to improve the absorption of the amendment by crops, preferably, the reversing assembly also includes an upper limit pin 15 and a lower limit pin 16, which are fixedly connected to the mounting plate 5, and the second connecting rod 12 is located between the upper limit pin 15 and the lower limit pin 16.

[0027] Specifically, by setting the upper limit pin 15 and the lower limit pin 16, the rotation angle of the nozzle 3 is limited, so that after the nozzle 3 is rotated, it is as vertical as possible to the leaves, avoiding the occurrence of spray blind spots, thereby improving the crop's absorption of the amendment and increasing crop yield.

[0028] To meet the spraying needs of crops at different heights, the lifting mechanism preferably includes: a guide groove 22, which is mounted on the vehicle body 1; a lead screw nut 23, which is slidably connected inside the guide groove 22; a ball screw 24, which is rotatably connected to the inner side of the guide groove 22, and the lead screw nut 23 is threadedly connected to the ball screw 24; and a drive unit 25, which is a stepper motor, and the output end of the drive unit 25 is fixedly connected to the ball screw 24.

[0029] An extension plate 26 is provided at the upper end of the guide groove 22, and the upper limit rod 13 is threadedly connected to the extension plate 26.

[0030] Specifically, depending on the height of the crop, the upper limit rod 13 is rotated to adjust its height to match the crop height. The drive unit 25 drives the ball screw 24 to rotate forward or backward. Under the guidance of the guide groove 22, the ball screw 24 drives the screw nut 23 to rise or fall. The stroke control of the screw is common knowledge to those skilled in the art and will not be elaborated here. Therefore, it can adapt to the spraying needs of crops of different heights, save amendments, and improve spraying efficiency.

[0031] To achieve the purpose of spraying the modifier solution, preferably, the spraying assembly also includes a liquid storage container 2 and a water pump 4. The liquid storage container 2 is installed on the vehicle body 1 and is used to store the modifier solution. The inlet end of the water pump 4 is connected to the liquid storage container 2, and the outlet end of the water pump 4 is connected to the nozzle 3.

[0032] Specifically, during the spraying of the improver solution, the water pump 4 extracts the improver solution stored in the storage container 2 and pressurizes it to be delivered to the nozzle 3, so that the improver solution is sprayed out from the nozzle 3.

[0033] Compared to existing technologies, this invention utilizes the coordinated arrangement of a vehicle body 1, a nozzle 3, a lifting mechanism, a mounting plate 5, a guide cylinder 6, a sliding rod 7, an elastic element 8, a driving gear 9, a driven gear 10, a first connecting rod 11, a second connecting rod 12, an upper limit rod 13, and a lower limit rod 14. The lifting mechanism drives the nozzle 3 and the mounting plate 5 to reciprocate upward and downward movements. During the upward movement of the nozzle 3 and the mounting plate 5, the nozzle 3 tilts upward and sprays the amendment solution onto the back of the crop leaves. When the second connecting rod 12 contacts the upper limit rod 13, the second connecting rod 12 is subjected to a downward squeezing force from the upper limit rod 13. The second connecting rod 12 drives the driving gear 9 to rotate, and the driving gear 9, through the driven gear 10, drives the nozzle 3 to rotate. The nozzle 3 is tilted downwards, and at the same time, the second connecting rod 12, through the first connecting rod 11, presses the sliding rod 7 into the guide cylinder 6, compressing the elastic element 8. After the first connecting rod 11 and the second connecting rod 12 change direction, the sliding rod 7 returns to its original position under the elastic potential energy of the elastic element 8. The lifting mechanism drives the nozzle 3 and the mounting plate 5 to descend. The downward-tilting nozzle 3 sprays the amendment solution onto the front of the crop leaves. When the second connecting rod 12 contacts the lower limit rod 14, the second connecting rod 12 is subjected to an upward squeezing force from the lower limit rod 14, and the nozzle 3 changes direction again. This cycle continues, coordinating with the movement of the vehicle body 1, to spray the amendment solution onto both the front and back of all crop leaves, improving the crop's absorption of the amendment and increasing crop yield.

[0034] Compared to existing technologies, this invention, through the coordinated arrangement of the connecting rod 17 and the long rod 18, allows the long rod 18 to move synchronously via the connecting rod 17 when the nozzle 3 is raised, lowered, or tilted. During the raising of the nozzle 3, the long rod 18 contacts the back of the blades, flipping the drooping blades upwards. This facilitates the nozzle 3 spraying the amendment solution onto the back of the blades, avoiding blind spots in spraying and thus improving the crop's absorption of the amendment, thereby increasing crop yield.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
