Description

Technical Field

[0001] The invention relates to the technical field of fertilizer spreading equipment, in particular to a cold-resistant fertilizer spreading equipment and a spreading method for angelica sinensis overwintering. Background Art

[0002] Angelica sinensis is a traditional Chinese medicine with a long history. It has been used in traditional Chinese medicine for more than 2,000 years. It was first recorded in Shennong's Herbal Classic and was listed as a medium-grade product. Its main production areas are Gansu, Yunnan, Sichuan and other places. Ancient medical books have many descriptions of the medicinal value of Angelica sinensis. For example, it has significant effects in treating gynecological diseases such as irregular menstruation, amenorrhea and dysmenorrhea, and is known as the "holy medicine for gynecology". It is also used in many prescriptions such as blood-tonifying and blood-activating, moisturizing and laxative, and is an important component of traditional Qi and blood-tonifying prescriptions such as Bazhen Decoction.

[0003] With the development of society and the progress of science, various agricultural machinery and implements have been put into use. During the process of fertilization, the equipment cannot adjust the range of fertilization and cannot adapt to the requirements of fertilization under different conditions. At the same time, fertilization is prone to uneven distribution of fertilizers, which may cause some plants to grow poorly and some plants to have excess nutrients. Summary of the invention

[0004] To achieve the above purpose, the present invention is implemented by the following technical scheme: a cold-resistant fertilizer spreading device for angelica overwintering, comprising a frame, a connecting piece is rotatably connected to the outer side of the frame, a transmission wheel is rotatably connected to one end of the connecting piece away from the frame, and a crawler is rotatably connected to the outer side of the transmission wheel;

[0005] A feeding assembly is fixedly mounted on the top of the frame, and a motor is fixedly connected to the outside of the feeding assembly;

[0006] A throwing assembly, which is fixedly installed at the bottom of the feeding assembly;

[0007] A limit assembly is fixedly mounted on the bottom of the frame and is located at the front end of the frame;

[0008] The feeding assembly comprises a shell, the inner wall of the shell is rotatably connected to a rotating shaft, the outer side of the rotating shaft is fixedly connected to a rotating drum, and the outer side of the rotating drum is fixedly connected to a fixed block;

[0009] Preferably, the throwing assembly includes a cylinder, which is fixedly connected to the bottom of the feeding assembly, and the fertilizer is added to the shell. The motor is connected to an external power supply, and the motor drives the shaft to rotate, so that the shaft drives the drum, so that the drum drives the fixed block on the outside to rotate, and the fixed block contacts and squeezes the limit block. The limit block is forced to drive the round rod downward, so that the fertilizer enters the inside of the cylinder through the through hole, and then the fertilizer moves downward along the spiral plate, so that the fertilizer flies out of the cylinder in a rotating state. By setting the spiral plate, the fertilizer will be evenly pushed and dispersed along the spiral line of the spiral plate. Due to the structural characteristics of the spiral line, the fertilizer can be thrown out at different angles and positions when leaving the cylinder, so as to achieve a more uniform distribution. The inner wall of the cylinder is fixedly connected with the spiral plate, and the middle part of the spiral plate is slidably connected with the round rod. The top of the round rod is fixedly connected with the limit block, and the side of the limit block is fixedly connected with a spring plate, and the end of the spring plate away from the limit block is fixedly connected with the shell.

[0010] Preferably, the output end of the motor passes through the shell, the fixed block is spirally arranged on the drum, and a through hole is opened at one end of the shell close to the spreading component. There are multiple through holes, and the multiple through holes are evenly arranged at the bottom of the shell. A circular plate is fixedly connected to the top of the through hole. Fertilizer is added to the inside of the shell, and the fertilizer falls above the filter plate. The motor is connected to an external power supply to work, the motor drives the shaft to rotate, the shaft drives the drum to rotate, and the drum drives the fixed block so that the fixed block contacts and squeezes the trapezoidal block at the bottom of the filter plate, and the filter plate is forced to move upward, and then the fixed block moves away from the filter plate. Under the action of the fertilizer and the filter plate's own gravity, the filter plate drives the fertilizer to move up and down, so that the fertilizer is screened, and the fertilizer that has not passed through the filter plate falls along the filter plate to the middle of the drum and the inclined plate, and is meshed with each other through the protrusion and the fixed block. The fertilizer is crushed into suitable particles before it can be evenly scattered through the spiral plate, which is conducive to the decomposition of the fertilizer by soil microorganisms and the absorption by the roots of crops. The round rod is slidably connected to the round plate, the inner wall of the shell is fixedly connected with a filter plate, the bottom of the filter plate is fixedly connected with a trapezoidal block, the inner wall of the shell is rotatably connected with an inclined plate, the side of the inclined plate close to the shell is fixedly connected with an elastic plate, the end of the elastic plate away from the inclined plate is fixedly connected to the shell, and the side of the inclined plate close to the rotating drum is fixedly connected with a protrusion. The surface of the particles after meshing and crushing is relatively smooth and has fewer edges and corners. The shape of the particles is conducive to the fluidity of the fertilizer in the soil, making it easier for the fertilizer to spread in the soil, and in the process of contact with soil microorganisms and water, it can better exert its fertilizer effect, and the protrusions and fixed blocks are alternately arranged.

[0011] Preferably, the round rod is fixedly connected with a fixing plate near the outer side of the circular plate, the fixing plate is located below the circular plate, there are two spring plates, the two spring plates are symmetrically arranged with the limit block as the center, the top of the limit block is inclined, and the inner wall of the cylinder is fixedly connected with the limit ring. In the initial state, under the elastic force of the spring plate, the fixing plate is located below the circular plate, and the top of the fixing plate contacts the bottom of the circular plate. At this time, the through hole is blocked by the fixing plate and the circular plate. When the rotating drum drives the fixing block to rotate, the fixing block and the limit block contact and squeeze are generated. Since the contact surface between the fixing block and the limit block is inclined, the fixing block is forced to drive the round rod to move downward. At this time, the round rod drives the fixing plate away from the circular plate, so that the fertilizer enters the interior of the cylinder through the through hole, and the rotating drum is driven to rotate by the rotating shaft, so that the equipment indirectly discharges the materials. The indirect discharge can avoid the fertilizer from gushing out in large quantities at one time, resulting in local accumulation. The limiting ring is located below the spiral plate, the bottom of the round rod is fixedly connected with a connecting block, and the bottom of the connecting block is fixedly connected with a positioning component.

[0012] Preferably, the positioning assembly includes a positioning rod, the top of the positioning rod is fixedly connected to the bottom of the connecting block, the outer side of the positioning rod is slidably connected to a slider, the outer side of the slider is rotatably connected to a connecting rod, and the outer side of the connecting block is fixedly connected to a bending plate, the bending plate is elastic, and the bending plate can be extended to adapt to angelica plants at different growth stages. Angelica seedlings are relatively small and have a narrow root distribution range. At this time, the range of the bending plate is reduced, and the fertilizer can be accurately concentrated in a smaller area around the roots of the seedlings. This can ensure that the seedlings obtain sufficient nutrients in the early stages of growth, and will not cause excessive growth of surrounding weeds or waste of fertilizer due to the large distribution range of the fertilizer. When the angelica is close to maturity, root growth and nutrient accumulation are the key. Properly adjusting the range of the bending plate so that the fertilizer is focused on the area around the roots helps to improve the quality and yield of the angelica roots. At this time, the range of the bending plate can be flexibly adjusted according to the size of the plant and the distribution of the root system, while ensuring that the plant is not damaged. It is generally slightly smaller than the range of the peak growth period to concentrate nutrients on the roots. There are multiple connecting rods, and the multiple connecting rods are evenly distributed around the positioning rod. The interior of the bending plate is rotatably connected to the end of the connecting rod away from the slider, and a return spring is fixedly connected to the side of the connecting block close to the slider, and the end of the return spring away from the connecting block is fixedly connected to the slider.

[0013] Preferably, the limit assembly includes a convex plate, the outer side of the convex plate is fixedly connected to a compression spring, the number of the convex plates is two, the two convex plates are evenly distributed with the compression spring as the center, and the convex plate is fixedly connected to an arc plate at one end close to the frame body, and the transmission wheel drives the crawler to rotate, thereby driving the equipment to move, so that the frame drives the convex plate to move, so that the arc plate shovels the soil on the side of the plant to achieve the weeding effect. At the same time, the shoveled soil moves along the arc plate, contacts the limit plate, and then falls back to the ground along the curvature of the limit plate. During the movement, due to different production conditions of plants, the distance between the arc plates is different, and the angle of rotation of the convex plates around the connecting rod is different, so that the convex plate electric limit bar moves toward the middle. At this time, the limit bar and the spiral rod rotate relative to each other, and the spiral rod moves upward. At this time, the spiral rod moves upward on the positioning rod. When the round rod drives the positioning assembly to move downward, the slider contacts and the spiral rod and is squeezed, and the reset spring is The force is compressed and deformed, so that under the support of the connecting rod, the bent plate extends outward, and the fertilizer spirally flying out of the cylinder falls into the ground along the bent plate. By setting the bent plate, the fertilizer particles can be effectively prevented from directly contacting the plants, so that the fertilizer passes through the blocking of the bent plate and falls into the soil around the plants, thereby avoiding physical and chemical damage to the plants. The arc plate is fixedly connected to the limit plate at the outside away from the compression spring, and the top of the convex plate is fixedly connected to the connecting rod, and the end of the connecting rod away from the convex plate is fixedly connected to the frame body, and the end of the convex plate away from the arc plate is fixedly connected to the limit strip, and the limit strip is spirally connected to the spiral rod, and a spiral rod is arranged in the middle of the two convex plates, and the outer side of the spiral rod is rotatably connected to the inner wall of the limit strip, and the outer side of the spiral rod is fixedly connected to a positioning ring, and the bottom of the spiral rod is fixedly connected to a bottom plate, and the positioning ring is located above the limit strip, and the top of the spiral rod is slidably connected to the outer side of the positioning rod, and the positioning rod is slidably connected to the spiral rod.

By setting the spiral plate 74, the fertilizer will be evenly pushed and dispersed along the spiral line of the spiral plate 74.

[0043] The second embodiment is based on the first embodiment. Figures 6 to 10As shown, the output end of the motor 6 passes through the shell 51, and the fixed block 54 is spirally arranged on the drum 53. A through hole 55 is opened at one end of the shell 51 close to the spreading component 7. There are multiple through holes 55, and the multiple through holes 55 are evenly arranged at the bottom of the shell 51. A circular plate 56 is fixedly connected to the top of the through hole 55.

The drum 53 drives the fixed block 54, so that the fixed block 54 contacts and squeezes the trapezoidal block 57 at the bottom of the filter plate 58, and the filter plate 58 is forced to move upward, and then the fixed block 54 moves away from the filter plate 58. Under the action of the gravity of the fertilizer and the filter plate 58, the filter plate 58 drives the fertilizer to move up and down, so that the fertilizer is screened.

Only when the fertilizer is crushed into suitable particles can it be evenly scattered through the spiral plate 74, which is conducive to the decomposition of the fertilizer by soil microorganisms and the absorption by the roots of crops. The round rod 72 is slidably connected to the circular plate 56. The inner wall of the shell 51 is fixedly connected with a filter plate 58, and the bottom of the filter plate 58 is fixedly connected with a trapezoidal block 57. The inner wall of the shell 51 is rotatably connected with an inclined plate 511. The side of the inclined plate 511 close to the shell 51 is fixedly connected with an elastic plate 59, and the end of the elastic plate 59 away from the inclined plate 511 is fixedly connected to the shell 51. The side of the inclined plate 511 close to the drum 53 is fixedly connected with a protrusion 510. The surface of the particles after meshing and crushing is relatively smooth and has fewer edges and corners. The shape of the particles helps the fluidity of the fertilizer in the soil, making it easier for the fertilizer to spread in the soil. In addition, in the process of contact with soil microorganisms and water, it can better exert its fertilizer effect. The protrusions 510 and the fixed blocks 54 are alternately arranged.

[0044] The round rod 72 is fixedly connected to the outer side of the circular plate 56 with a fixing plate 73, and the fixing plate 73 is located below the circular plate 56. There are two spring plates 75, and the two spring plates 75 are symmetrically arranged with the limit block 76 as the center. The top of the limit block 76 is inclined.

Since the contact surface between the fixing block 54 and the limiting block 76 is inclined, the fixing block 54 is forced to drive the round rod 72 to move downward. At this time, the round rod 72 drives the fixing plate 73 away from the round plate 56, so that the fertilizer enters the interior of the cylinder 71 through the through hole 55, and drives the rotating cylinder 53 to rotate through the rotating shaft 52, so that the equipment can indirectly discharge the fertilizer.

This can ensure that the seedlings obtain sufficient nutrients in the early stage of growth, and will not cause excessive growth of surrounding weeds or waste of fertilizer due to the large distribution range of the fertilizer. When the angelica is close to maturity, the growth and nutrient accumulation of the roots are the key. Properly adjusting the range of the bending plate 775 so that the fertilizer is mainly supplied to the area around the roots helps to improve the quality and yield of the angelica roots. At this time, the range of the bending plate 775 can be flexibly adjusted according to the size of the plant and the distribution of the root system, while ensuring that the plant is not damaged. It is generally slightly smaller than the range of the peak growth period to concentrate nutrients on the roots. There are multiple connecting rods 774, and the multiple connecting rods 774 are evenly distributed around the positioning rod 771.

At the same time, the shoveled soil moves along the arc plate 82, contacts with the limiting plate 83, and then moves along The curvature of the limit plate 83 falls back into the ground. During the movement, due to different production conditions of plants, the distance between the arc plates 82 is different, and the angles of rotation of the convex plate 81 around the connecting rod 84 are different, so that the convex plate 81 drives the limit bar 86 to move toward the middle. At this time, the limit bar 86 and the spiral rod 89 rotate relatively, and the spiral rod 89 moves upward. At this time, the spiral rod 89 moves upward on the positioning rod 771.
