Description

Technical Field

[0001] The utility model belongs to the technical field of foliar fertilizer application, and in particular relates to a foliar fertilizer spraying device. Background Art

[0002] Foliar fertilizer is a fertilizer that is completely dissolved and then sprayed on the leaves. The leaves directly absorb and utilize the nutrients in it to achieve the purpose of promoting growth. Foliar fertilizer can be absorbed not only on the leaf surface, but also on the back of the leaf.

[0003] During large-scale fertilization, foliar fertilizers are mainly sprayed above the leaves. At the same time, the bottom of plants with overlapping leaves are difficult to receive foliar fertilizers, and the amount of fertilizer applied on the back of the leaves is close to zero. Therefore, in order to improve the spraying efficiency and absorption efficiency of foliar fertilizers, a new foliar fertilizer spraying device is needed. Utility Model Content

[0004] The utility model provides a foliar fertilizer spraying device, which has the characteristics of utilizing the planting characteristics of interval-type plants and adopting an edge ring-surrounded interlaced fertilization method to realize precise fertilization.

[0005] The utility model provides the following technical scheme: it includes a support frame assembly, a liquid supply assembly, and a rotary drive assembly, wherein the support frame assembly includes two horizontal support frames, a middle support frame, and two self-propelled mobile four-wheel frames, wherein the middle support frame is located in the middle and connects the two self-propelled mobile four-wheel frames through the horizontal support frame, the liquid supply assembly is installed on the side of the self-propelled mobile four-wheel frames, and the rotary drive assembly is installed on the top of the middle support frame, and a fertilizer cross-pipeline is arranged on the side of the rotary drive assembly, and the other end of the fertilizer cross-pipeline is fixedly connected to the middle support frame, and a plurality of longitudinally extended fertilizer branches are horizontally and equidistantly fixed on the fertilizer cross-pipeline, a rotary sweep blade fertilizer combination pipeline is rotated at the bottom of the longitudinally extended fertilizer branch, and a multi-linkage control mechanism is arranged on the top of the longitudinally extended fertilizer branch, and the rotary drive assembly drives the rotary sweep blade fertilizer combination pipeline to rotate synchronously through a plurality of the multi-linkage control mechanisms;

[0006] The rotary sweep blade fertilization combination pipeline includes a horizontal curved pipe rotatably connected to the longitudinally extending fertilization branch and a bottom pipe fixedly connected to the bottom of the horizontal curved pipe, and a plurality of blade gap rotary sweep pipes are fixedly connected to the side of the connecting pipeline between the horizontal curved pipe and the bottom pipe. The length of the horizontal curved pipe is greater than the length of the blade gap rotary sweep pipe and the bottom pipe. A plurality of linearly distributed nozzles are arranged at the bottom of the horizontal curved pipe, a plurality of linearly distributed nozzles are arranged on the top and bottom surfaces of the blade gap rotary sweep pipe, and a plurality of linearly distributed nozzles are arranged on the top surface of the bottom pipe.

[0007] Among them, the multi-linkage control mechanism includes a rotating disk rotatably connected to the top of the longitudinally extending fertilization branch, two driving gears are fixedly connected to the top of the rotating disk, and the two adjacent driving gears are connected by a linkage toothed belt transmission. The linkage toothed belt close to the side of the rotating drive component is connected to the driving wheel inside the rotating drive component, and the bottom surface of the rotating disk is fixedly connected to the rotary sweeping blade fertilization combination pipeline through a driving vertical rod.

[0008] Wherein, when the middle supporting bracket and the self-propelled movable four-wheel bracket are in contact with the ground, the bottom pipe is not in contact with the ground.

[0009] Wherein, a rotary sealing mechanism is arranged between the horizontal curved pipe and the longitudinally extending fertilization branch.

[0010] There is a spacing between the longitudinally extending fertilization branch and the fertilization cross-pipeline to accommodate the rotation of the driving vertical rod.

[0011] The beneficial effects of the utility model are:

[0012] The rotary sweep blade fertilizer combination pipeline is eccentrically set with the fertilizer cross pipeline as the center. In static state, the rotary sweep blade fertilizer combination pipeline is located on the side of the plant. When the rotary sweep blade fertilizer combination pipeline moves, it will not cause damage to the central branches of the plant. Although the blade gap rotary sweep pipe and the bottom pipe will pass through the blade, the arc-shaped structure will guide the blade to move up and down, so that the blade gap rotary sweep pipe is located in the gap of the blade. When the rotary drive assembly drives the blade gap rotary sweeping tube to rotate, the nozzle below the horizontal curved pipe can completely spray on the upper surface of the plant, while the blade gap rotary sweeping tube and the bottom pipe are interfered by the mid-diameter of the plant during rotation. The length of the blade gap rotary sweeping tube and the bottom pipe is shorter than the horizontal curved pipe. Therefore, the blade gap rotary sweeping tube and the bottom pipe will be interspersed between the leaves and rotate around the mid-diameter. The nozzle of the blade gap rotary sweeping tube sprays the back and surface of the leaves, and the bottom pipe sprays the back of the lowest leaf through the nozzle above. This patent mainly utilizes the characteristics of interval-type planting of crops to achieve precise spraying on the leaf surface and back, thereby improving absorption effect and fertilization efficiency.

[0013] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] See also Figure 1-Figure 4 The utility model provides the following technical solutions: including a support frame assembly 1, a liquid supply assembly 2, and a rotary drive assembly 3. The support frame assembly 1 includes two horizontal support frames 11, a middle support frame 12, and two self-propelled mobile four-wheel frames 13. The middle support frame 12 is located in the middle and is connected to the two self-propelled mobile four-wheel frames 13 through the horizontal support frame 11. The liquid supply assembly 2 is installed on the side of the self-propelled mobile four-wheel frames 13. The rotary drive assembly 3 is installed on the top of the middle support frame 12. A fertilizer cross-pipeline 4 is arranged on the side of the rotary drive assembly 3. The other end of the fertilizer cross-pipeline 4 is fixedly connected to the middle support frame 12. A plurality of longitudinally extended fertilizer branches 41 are horizontally and equidistantly fixed on the fertilizer cross-pipeline 4. A rotary sweep blade fertilizer combination pipeline 5 is rotated at the bottom of the longitudinally extended fertilizer branch 41. A multi-linkage control mechanism 6 is arranged on the top of the longitudinally extended fertilizer branch 41. The rotary drive assembly 3 drives the rotary sweep blade fertilizer combination pipeline 5 to rotate synchronously through a plurality of multi-linkage control mechanisms 6.

[0020] The rotary sweep blade fertilization combination pipeline 5 includes a horizontal curved pipe 51 rotatably connected to the longitudinally extending fertilization branch 41 and a bottom pipe 53 fixedly connected to the bottom of the horizontal curved pipe 51. A plurality of blade gap rotary sweep pipes 52 are fixedly connected to the side of the connecting pipeline between the horizontal curved pipe 51 and the bottom pipe 53. The length of the horizontal curved pipe 51 is greater than the lengths of the blade gap rotary sweep pipe 52 and the bottom pipe 53. A plurality of linearly distributed nozzles 54 are arranged at the bottom of the horizontal curved pipe 51, a plurality of linearly distributed nozzles 54 are arranged on the top and bottom surfaces of the blade gap rotary sweep pipe 52, and a plurality of linearly distributed nozzles 54 are arranged on the top surface of the bottom pipe 53.

[0021] In this embodiment: the self-propelled four-wheel bracket 13 is located at both ends, and the middle support bracket 12 is located in the middle. The wheels of the self-propelled four-wheel bracket 13 rotate to drive the entire support frame assembly 1 to translate on the plant planting coverage surface. The horizontal support frame 11 connects the middle support bracket 12 and the self-propelled four-wheel bracket 13 to ensure integrity. The liquid supply assembly 2 is installed at the self-propelled four-wheel bracket 13 to provide liquid for the fertilizer cross-pipeline 4. This patent mainly uses the characteristics of interval planting crops to achieve precise spraying on the leaf surface and back of the leaf, and improves the absorption effect and fertilization efficiency.

[0022] First, the self-propelled four-wheeled support 13 can be controlled by the controller to move one step at a time, and the step is the plant planting spacing. Each time the self-propelled four-wheeled support 13 moves one step, the rotary drive assembly 3 drives the rotary sweep blade fertilization combination pipeline 5 to rotate 360 ​​degrees through the multi-link control mechanism 6. Since this control method is a conventional technical means and is very mature, the control principle will not be repeated here.

[0023] The rotary sweep blade fertilizer combination pipeline 5 is eccentrically arranged with the fertilizer cross pipeline 4 as the center. In static state, the rotary sweep blade fertilizer combination pipeline 5 is located on the side of the plant. When the rotary sweep blade fertilizer combination pipeline 5 moves, it will not cause damage to the central branches of the plant. Although the blade gap rotary sweep pipe 52 and the bottom pipe 53 will pass through the blade, the arc-shaped structure will guide the blade to move up and down, so that the blade gap rotary sweep pipe 52 is located at the gap of the blade. When the rotary drive component 3 drives the blade gap rotary sweeping tube 52 to rotate, the nozzle 54 below the horizontal curved pipe 51 can completely spray on the upper surface of the plant, and the blade gap rotary sweeping tube 52 and the bottom tube 53 are subject to interference at the mid-diameter of the plant during rotation. The blade gap rotary sweeping tube 52 and the bottom tube 53 are shorter than the horizontal curved pipe 51, so the blade gap rotary sweeping tube 52 and the bottom tube 53 will be inserted between the blades and rotate around the mid-diameter. The nozzle 54 of the blade gap rotary sweeping tube 52 sprays the back and surface of the leaves, and the bottom tube 53 sprays the back of the lowest leaf through the nozzle 54 above.

[0024] In this embodiment: the multi-linkage control mechanism 6 includes a rotating disk 61 rotatably connected to the top of the longitudinally extending fertilization branch 41, two driving gears 62 are fixedly connected to the top of the rotating disk 61, and the two adjacent driving gears 62 are connected by a linkage toothed belt 63. The linkage toothed belt 63 on the side close to the rotary drive component 3 is connected to the driving wheel inside the rotary drive component 3, and the bottom surface of the rotating disk 61 is fixedly connected to the rotary sweep blade fertilization combination pipeline 5 through a driving vertical rod 64.

[0025] Due to the interference of the bracket, the multi-link control mechanism 6 is set above the longitudinally extending fertilization branch 41, and the rotating disk 61 rotates around the longitudinally extending fertilization branch 41. After the driving gear 62 is fixedly connected to the rotating disk 61, the linkage toothed belt 63 can drive the driving gear 62 to rotate, thereby rotating the rotating disk 61. When the rotating disk 61 rotates, the rotary sweep blade fertilization combination pipeline 5 can be driven to rotate by driving the vertical rod 64, thereby realizing this process. Multiple linkage toothed belts 63 are alternately driven with the driving gear 62, and coordinated rotation can be achieved by connecting a linkage toothed belt 63 to the main gear inside the rotating drive component 3.

[0026] When the middle support bracket 12 and the self-propelled mobile four-wheel bracket 13 are in contact with the ground, the bottom pipe 53 is not in contact with the ground; in order to fertilize the back of the lowest leaves of the plant, the bottom pipe 53 is not in contact with the ground to increase its service life.

[0027] A rotary sealing mechanism is provided between the horizontal curved pipe 51 and the longitudinally extending fertilization branch 41; the rotary sealing mechanism may select a rotary sealing ring for sealing, thereby ensuring rotation and improving sealing performance.

[0028] There is a spacing between the longitudinally extending fertilization branch 41 and the fertilization cross-pipe 4 to accommodate the rotation of the driving vertical rod 64; in order to avoid the interference of the fertilization cross-pipe 4 and the longitudinally extending fertilization branch 41 on the rotation of the driving vertical rod 64, the normal operation of the device is met.
