Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and more particularly to a vertical quantitative layered fertilization mechanism. Background Art

[0002] Fertilization is one of the important factors to increase the yield per unit area of ​​crops, and it plays an indispensable role in modern agricultural production. However, the current fertilizer utilization rate in my country is still low, and the purpose of increasing production can only be achieved by applying a large amount of chemical fertilizers, which has caused many problems such as destroying the soil nutrient structure, polluting groundwater sources, affecting the atmospheric environment and harming crops. Therefore, improving the fertilizer utilization rate and reducing the amount of fertilizer used are of great significance to the ecological environment, food safety and production costs.

[0003] At the same time, my country's fertilization technology is backward, and the main fertilization methods are artificial surface spreading in stages or one-time fertilization during sowing, resulting in high fertilization costs and low fertilizer utilization. Most of the existing layered fertilization mechanisms are welded on the back of the deep loosening shovel handle, which cannot solve the problems of quantitative layer control and fertilizer port blockage, resulting in the inability to promote and apply them on a large scale.

[0004] Therefore, how to provide a vertical quantitative stratified fertilization mechanism that can quantitatively stratify fertilizers, improve fertilizer utilization, and avoid clogging of fertilizer ports is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a vertical quantitative stratified fertilization mechanism which can fertilize in a quantitative and stratified manner, improve the utilization rate of fertilizers, and avoid clogging of a fertilization port.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A vertical quantitative layered fertilization mechanism, comprising:

[0008] A connecting seat, wherein a fertilizer flow channel is provided inside the connecting seat and runs through the upper and lower surfaces thereof;

[0009] An outer sleeve, the top end of which is fixedly connected to the bottom end of the connecting seat, and the outer sleeve is in communication with the fertilizer flow channel;

[0010] An inner sleeve, wherein the inner sleeve is sleeved in the outer sleeve, and the two are coaxially arranged, a lower sealing baffle is fixedly connected to the outer peripheral side of the bottom end of the inner sleeve, and the lower sealing baffle is fixedly connected to the inner cylinder wall of the outer sleeve;

[0011] An upper fertilizer cavity is defined between the inner sleeve and the outer sleeve, an upper fertilizer outlet communicating with the upper fertilizer cavity is provided on the wall of the outer sleeve, a lower fertilizer cavity is provided inside the outer sleeve below the lower sealing baffle, the lower end of the inner sleeve is communicated with the lower fertilizer cavity, and a lower fertilizer outlet communicating with the lower fertilizer cavity is provided on the wall of the outer sleeve;

[0012] Wherein, soil breaking components are fixedly connected to the positions of the upper fertilizer outlet and the lower fertilizer outlet on the wall of the outer sleeve.

[0013] It can be seen from the above technical solution that, compared with the prior art, the present invention discloses a vertical quantitative layered fertilization mechanism. After passing through the fertilizer flow channel, a part of the fertilizer enters the upper fertilizer cavity and is discharged through the upper fertilizer outlet, and the other part enters the inner sleeve and the lower fertilizer cavity and is discharged through the lower fertilizer outlet, thereby realizing quantitative layered fertilization, improving fertilizer utilization and operating efficiency, and saving time and labor.

[0014] Furthermore, an upper sealing baffle is fixedly connected between the inner sleeve and the outer sleeve, the upper sealing baffle is located above the lower sealing baffle, the upper fertilizer outlet is located above the upper sealing baffle, and a fertilizer guide channel is fixedly installed at the position of the upper fertilizer outlet, a spiral slide is arranged in the upper fertilizer cavity, and the lower end of the spiral slide corresponds to the inlet of the fertilizer guide channel.

[0015] The beneficial effect of adopting the above technical solution is that the arrangement of the spiral slideway and the fertilizer guiding channel is conducive to the discharge of fertilizers and avoids the problem of fertilizers accumulating in the upper fertilizer cavity and causing blockage.

[0016] Furthermore, an inclined material guide plate is fixedly installed inside the outer sleeve, and the inclined material guide plate is located below the lower sealing partition, and the lower fertilizer cavity is formed therebetween, and the lower end of the inclined material guide plate corresponds to the lower fertilizer outlet.

[0017] The beneficial effect of adopting the above technical solution is that the fertilizer falls onto the inclined guide plate through the inner sleeve and is discharged through the lower fertilizer outlet. The setting of the inclined guide plate is conducive to the discharge of the fertilizer and avoids the accumulation of fertilizer in the lower fertilizer cavity and blockage.

[0018] Furthermore, the earth-breaking component comprises:

[0019] A soil breaking claw, one side of which is adapted to the shape of the outer sleeve wall and fixedly connected;

[0020] A fertilization space upper plate, one end of which is fixedly connected to a position above the side end of the soil-breaking claw, and one side of which is fixedly connected to the wall of the outer sleeve;

[0021] A fertilization space stand, the upper surface of which is fixedly connected to the lower surface edge of the upper plate of the fertilization space, and the fertilization space stand is opposite to the outlet of the fertilizer guide channel or the outlet of the lower fertilizer layer;

[0022] A lower plate of the fertilizing space, wherein the side end of the lower plate of the fertilizing space is fixedly connected to a position below the side end of the soil breaking claw, and the upper surface of the lower plate of the fertilizing space is fixedly connected to the lower surface of the vertical plate of the fertilizing space;

[0023] A fertilization space is formed between the soil-breaking claws, the fertilization space upper plate, the fertilization space vertical plate and the fertilization space lower plate.

[0024] The beneficial effect of adopting the above technical solution is that when the machine is operating, the fertilization mechanism rotates accordingly, the soil-breaking component rotates accordingly, the soil is broken by the soil-breaking claws, and the fertilizer discharged through the outlet of the fertilizer guide channel and the lower fertilizer outlet enters the fertilization space to complete the fertilization. At the same time, the setting of the soil-breaking component also effectively prevents the problem of soil blocking the outlet of the fertilizer guide channel and the lower fertilizer outlet.

[0025] Furthermore, the side surface of the ground-breaking claw away from the outer sleeve is a ground-breaking surface.

[0026] Furthermore, the lower end of the outer sleeve is sealed, and a drill bit is fixedly connected to the sealed end.

[0027] Furthermore, two vertical rotary cutters are fixedly connected to the bottom end of the connecting seat, and the outer sleeve is located between the two vertical rotary cutters. BRIEF DESCRIPTION OF THE DRAWINGS
