Description

Technical Field

[0001] This utility model relates to the field of farmland soil fertility maintenance technology, and in particular to a rotary tillage and fertilizer burying device. Background Technology

[0002] In existing technologies, crop cultivation often requires first using a rotary tiller to till the soil, then applying fertilizer to the soil, and finally planting the seeds in the soil.

[0003] A search revealed a Chinese patent application with patent number 202421593989.7, which discloses an organic fertilizer application device for use with a rotary tiller. The device uses a guide cylinder and a bidirectional conveying screw to move fertilizer inside the guide cylinder, and a discharge net is provided at the bottom of the guide cylinder so that the fertilizer can be discharged from the guide cylinder, thereby achieving the purpose of fertilizing the soil. At the same time, the entire fertilization device, along with the mounting rod, can be installed on the rotary tiller mechanism to facilitate the direct application of fertilizer to the soil during rotary tillage, effectively improving the efficiency of soil fertilization.

[0004] The above-mentioned patent has the following shortcomings: In the process of fertilization, the device mainly spreads the fertilizer on the soil surface and uses the action of microorganisms and time to gradually release the fertilizer into the soil. However, the device will cause fertilizer loss (after rain, the fertilizer is easily washed away by rainwater) and slow fertilizer release (most microorganisms are averse to sunlight and cannot accept prolonged direct sunlight). Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rotary tillage and fertilizer burying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary tillage and fertilizer burying device, comprising:

[0008] A fertilizer storage box has multiple connecting cylinder arms welded at equal intervals at its bottom end for guiding fertilizer granules. A soil-breaking cone head for breaking the soil is fixedly installed at the bottom of the front end of the connecting cylinder arm.

[0009] A short-arm cutter shaft is fitted with a front-mounted protective shell, which is fixedly mounted on the lower part of the front of the fertilizer storage box. The short-arm cutter shaft is used to crush the surface soil.

[0010] The long-arm cutter shaft is equipped with a rear-mounted protective shell, which is fixedly installed on the lower part of the back of the fertilizer storage tank. The long-arm cutter shaft is used to crush deep soil to fully mix the soil and fertilizer.

[0011] As a further improvement of this utility model: a protective cover is fixedly installed on the top of the fertilizer storage box, and a fertilizer inlet groove is opened on the rear side of the top of the protective cover.

[0012] As a further embodiment of this utility model: a transmission shaft is provided on the front side of the top of the protective box cover, and multiple shaft support arms are equidistantly mounted on the outer wall of the transmission shaft. A drive bevel gear is fixedly sleeved on the outer wall of the transmission shaft between two adjacent shaft support arms.

[0013] As a further embodiment of this utility model: a drive motor is fixedly installed on one side of the front end of the fertilizer storage box, and a reducer is installed on the output shaft of the drive motor, and the reducer is connected to the transmission shaft.

[0014] As a further improvement of this utility model: the inner cavity of the fertilizer storage box is welded with multiple mounting partitions at equal intervals, the mounting partitions divide the inner cavity of the fertilizer storage box into multiple fertilizer chambers, and a cross bracket is fixedly installed on the top of the fertilizer chamber.

[0015] As a further improvement of this utility model: a limiting rotating cylinder is fixedly connected inside the cross bracket, and a discharge rotating shaft is rotatably installed inside the limiting rotating cylinder.

[0016] As a further improvement of this utility model: the top of the discharge shaft passes through the protective box cover and extends upward, and a driven bevel gear that meshes with the driving bevel gear is fixedly installed at its extended end.

[0017] As a further embodiment of this utility model: a discharge auger blade is welded to the lower outer wall of the discharge shaft, and a collection hopper is sleeved on the lower part of the discharge auger blade.

[0018] Compared with the prior art, this utility model provides a rotary tillage and fertilizer burying device, which has the following beneficial effects:

[0019] 1. This rotary tillage and fertilizer-burying device uses a soil-dividing cone that is inserted into the soil synchronously as the device moves. Its symmetrical structure on both sides facilitates natural backfilling and covering of fertilizer trenches after the soil is broken, reducing direct erosion of fertilizer by the external environment. The short-arm cutter shaft first crushes the surface soil, reducing the soil-dividing cone's resistance to breaking the soil. At the same time, the loose soil after crushing is easier to cover with fertilizer, further reducing the risk of fertilizer loss. The long-arm cutter shaft and the short-arm cutter shaft form a three-dimensional tillage system. The short-arm cutter shaft is responsible for crushing and initially mixing the surface soil, while the long-arm cutter shaft deeply tills the middle and deep soil layers. Through synchronous operation via sprockets, chains, or gearboxes, the linearly distributed fertilizer particles are fully mixed with the surrounding soil. Under the action of soil moisture or rainwater, the fertilizer dissolution is accelerated, the fertilizer release cycle is shortened, and the fertilizer utilization rate is improved.

[0020] 2. This rotary tillage and fertilizer burying device achieves uniform distribution and stable delivery of fertilizer through the design of the discharge shaft and discharge auger blades inside the fertilizer storage box; the discharge auger blades are driven by multiple driven bevel gears in a synchronous manner by the drive bevel gear, which drives each discharge shaft to rotate synchronously, ensuring simultaneous discharge from multiple points, avoiding fertilizer accumulation or uneven discharge, and improving fertilization efficiency and uniformity.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] A rotary tillage and fertilizer burying device, such as Figures 1 to 4 As shown, it includes: a short-arm cutter shaft 10 for crushing topsoil, a fertilizer spreading device for deep burial of granular fertilizer, and a long-arm cutter shaft 12 for crushing deep soil and thoroughly mixing soil and fertilizer.

[0029] The vertical ladder of the fertilizer spreading device is set as a fertilizer storage box 1. A protective box cover 2 is fixedly installed on the top of the fertilizer storage box 1. A fertilizer inlet groove 3 is opened on the rear side of the top of the protective box cover 2 to facilitate the pouring of granular fertilizer (such as urea granules, compound fertilizer granules) into the fertilizer storage box 1.

[0030] Multiple mounting partitions 16 are welded at equal intervals in the inner cavity of the fertilizer storage box 1. The mounting partitions 16 divide the inner cavity of the fertilizer storage box 1 into multiple fertilizer chambers. A cross bracket 17 is fixedly installed on the top of the fertilizer chamber, and the top of the mounting partition 16 is lower than the top of the fertilizer storage box 1, so as to facilitate the flow of granular fertilizer into the multiple fertilizer chambers.

[0031] The cross bracket 17 is internally fixedly connected to a limiting rotating cylinder 18. The limiting rotating cylinder 18 is internally rotatably mounted with a discharge rotating shaft 19. The top of the discharge rotating shaft 19 passes through the protective box cover 2 and extends upward. The extended end is fixedly mounted with a driven bevel gear 20, and the top of the discharge rotating shaft 19 is rotatably connected to the protective box cover 2.

[0032] The lower outer wall of the discharge shaft 19 is welded with discharge auger blades 21, and the lower part of the discharge auger blades 21 is fitted with a collection hopper 22. The outer wall of the collection hopper 22 is set to match the lower inner wall of the fertilizer chamber and is fixed inside the fertilizer chamber. The discharge port at the bottom of the collection hopper 22 passes through the bottom box of the fertilizer storage box 1, which facilitates the discharge auger blades 21 to discharge granular fertilizer.

[0033] A transmission shaft 4 is provided on the front side of the top of the protective box cover 2. Multiple shaft support arms 5 are equidistantly mounted on the outer wall of the transmission shaft 4. A drive bevel gear 6 is fixedly sleeved on the outer wall of the transmission shaft 4 between two adjacent shaft support arms 5. The multiple drive bevel gears 6 mesh with multiple driven bevel gears 20 respectively, so that multiple discharge shafts 19 rotate synchronously, and granular fertilizer is discharged at multiple points at the same time.

[0034] A drive motor 7 is fixedly installed on one side of the front end of the fertilizer storage tank 1. The drive motor 7 is equipped with a battery module (a mature technology, and its control circuit and circuit components are not described in detail in this application). A reducer 8 is installed on the output shaft of the drive motor 7. The reducer 8 is connected to the transmission shaft 4, and then drives the discharge shaft 19 through the transmission shaft 4 to stably discharge granular fertilizer (the discharge speed of granular fertilizer is adjusted by adjusting the output speed of the reducer 8, and the specific discharge speed is determined according to the overall travel speed of the device).

[0035] Multiple connecting cylinder arms 14 for guiding fertilizer granules are welded at equal intervals to the bottom of the fertilizer storage box 1. Each connecting cylinder arm 14 corresponds to the discharge port of a collection hopper 22. A soil-dividing cone 15 for breaking the soil is fixedly installed at the bottom of the front end of the connecting cylinder arm 14. During the movement of the whole device, the soil-dividing cone 15 gradually inserts into the soil and breaks the soil, so that the granular fertilizer falls into the soil trench broken by the soil-dividing cone 15. The soil-dividing cone 15 is symmetrical on both sides, which makes it easy for the separated soil to cover the soil trench again.

[0036] A front-mounted protective shell 9 is fixedly installed on the lower front of the fertilizer storage box 1, and a short-arm cutter shaft 10 is rotatably installed inside the front-mounted protective shell 9; the short-arm cutter shaft 10 crushes the soil to a depth of about ten centimeters, and the bottom of the soil dividing cone 15 is inserted into the soil to a depth of about twelve to fifteen centimeters; at the same time, the soil crushed by the short-arm cutter shaft 10 reduces the difficulty of the soil dividing cone 15 to break the soil, and the crushed soil can be more easily used to cover the soil trench.

[0037] A rear-mounted protective shell 11 is fixedly installed on the lower part of the back of the fertilizer storage box 1. The long-arm blade shaft 12 is rotatably installed inside the rear-mounted protective shell 11. The long-arm blade shaft 12 crushes the soil to a depth of sixteen to eighteen centimeters, improving the soil turning effect. At the same time, it makes the linearly distributed granular fertilizer fully mixed with the surrounding soil. Under the action of soil moisture or rainwater, it dissolves quickly and fully integrates into the soil, reducing the loss of granular fertilizer fertility and shortening the time of granular fertilizer fertility release.

[0038] The two ends of the long arm cutter shaft 12 and the short arm cutter shaft 10 are connected by a sprocket and chain (structure shown in the figure), or one end of the two is driven by a gearbox. Those skilled in the art can install the sprocket and chain according to the structure of the overall device, and equip it with a tension wheel (to adjust the chain tension), a protective wheel (to prevent the chain from touching the ground), and a protective shell, etc.

[0039] The driving method of the long arm cutter shaft 12 and the short arm cutter shaft 10 is illustrated in the figure of this application as an engine 13. The engine 13 is connected to one end of the long arm cutter shaft 12 through a sprocket, chain or belt pulley. The engine 13 can be fueled by diesel or gasoline.

[0040] Furthermore, the driving methods of the long arm cutter shaft 12 and the short arm cutter shaft 10 can be adjusted according to the traction machinery and existing rotary tiller technology, such as the tractor power take-off shaft drive in the existing technology (directly driving the working parts of the rotary tiller, such as the cutter shaft and blades, through the tractor's power take-off shaft).

[0041] Working principle:

[0042] Please refer to Figures 1 to 4Assemble the device as shown in the figure; and connect the device to the tractor (e.g., a tractor; the connection method can refer to the existing connection method between a seeder and a tractor).

[0043] When using this device, firstly, a sufficient amount of granular fertilizer (evenly distributed inside multiple fertilizer chambers) is introduced into the fertilizer storage tank 1. Then, the engine 13 and drive motor 7 are started, and the device is moved synchronously in the field. The short-arm cutter shaft 10 first crushes, turns over, and mixes the surface soil. The soil-dividing cone 15 extends into the soil to dig trenches. At the same time, the discharge shaft 19 stably discharges the granular fertilizer through the discharge auger blades 21, so that the granular fertilizer falls stably into the trenches. Finally, the long-arm cutter shaft 12 deeply tills the soil, improves the soil turning effect, and at the same time, makes the linearly distributed granular fertilizer fully mixed with the surrounding soil.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
