Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a farmland restoration and deep plowing device. Background Art

[0002] Farmland restoration often uses deep plowing and deep plowing and fertilization at the same time, mixing fertilizer into the soil and evenly distributing it throughout the soil to restore farmland. During deep plowing and fertilization, the soil structure can be protected to avoid soil compaction and fertility loss caused by excessive tillage. Existing deep plowing equipment has the following problems: first, the deep plowing depth adjustment is not accurate enough, which will cause damage to the root system of crops; second, the amount of fertilizer is not accurately controlled. Since organic fertilizer is easy to stick together, it is easy to make the amount of fertilizer inaccurate when applying fertilizer; third, deep plowing and fertilization need to be divided into deep plowing, fertilization, and covering procedures, which has low operation efficiency and poor economy; fourth, it cannot solve the problem of soil compaction. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a farmland restoration deep plowing device which can accurately control the fertilization depth and amount, add fertilizer to the bottom of the soil after deep plowing, and does not need to be covered, thereby avoiding soil compaction and restoring the farmland.

[0004] The purpose of the present invention is to be achieved through the following technical solutions: A farmland restoration deep plowing device comprises a front frame, which is connected to a rear frame via a connecting rod, the front frame is rotatably connected to a lead screw, the lead screw is connected to a nut, the nut is connected to a spline shaft, the spline shaft is connected to the rear frame, the rear frame is rotatably connected to a group of spiral shafts, the lower part of the rear frame is rotatably connected to a No. 1 shaft, the No. 1 shaft is connected to a group of fertilizer application devices via a connecting rod, the group of fertilizer application devices is connected to the rear frame, and the fertilizer application devices comprise a plowing seat and a vibration seat hinged to each other.

[0005] The rear side of the front frame is provided with four front frame hinge seats in rectangular distribution, the front side of the rear frame is provided with a connecting seat, and the front side of the connecting seat is provided with four rear frame hinge seats in rectangular distribution. The four front frame hinge seats and the four rear frame hinge seats correspond to each other one by one, and the corresponding front frame hinge seats and rear frame hinge seats are connected by a No. 2 connecting rod. The upper part of the front frame is provided with a screw hole, and the screw hole is rotatably connected to the screw, and the screw is threadedly connected to the nut. A spline hole is provided on the rear side of the connecting seat, and the spline shaft is slidably connected in the spline hole. The guide rod on the upper part of the nut is slidably connected to the spline shaft hole on the upper part of the spline shaft. A spring is provided between the nut and the spline shaft, and the spring is sleeved on the outside of the spline shaft. The upper and lower sides of the spline shaft respectively resist the connecting seat and the guide rod.

[0006] A fat bucket is provided on the upper part of the rear frame, and two rear frame bearing seats are provided on the upper part of the fat bucket. A group of discharge barrels are evenly distributed at the bottom of the fat bucket. The rear frame bearing seat is rotatably connected to the No. 2 shaft, and the No. 2 shaft is fixedly connected to a group of No. 1 bevel gears. The No. 1 bevel gears and the No. 2 bevel gears are meshed with each other. Each No. 2 bevel gear is fixedly connected to the upper part of the spiral shaft, and the lower part of the spiral shaft is rotatably connected to the corresponding discharge barrel. The No. 2 shaft is connected to the speed regulator fixed on the side of the rear frame through a sprocket chain, and the speed regulator is connected to the reducer fixed on the front frame through a sprocket and a chain.

[0007] Beneficial effects: The front frame and the rear frame connected by the No. 2 connecting rod form a parallel connecting rod structure. The rotating screw drives the nut, the rear frame, and the fertilizer device to move up and down in parallel, so that the fertilizer device connected to the rear frame is always parallel to the ground, ensuring the consistency of the plowing depth of the fertilizer device. The threaded screw and nut can make the depth of the fertilizer device into the ground be finely controlled to ensure the required depth when fertilizing, accurately control the amount of fertilizer, and avoid soil pollution and poor crop growth caused by excessive fertilization. The spring makes the front frame and the rear frame in a suspended state, which not only cushions the impact of the device when moving, but also provides a buffering force when the fertilizer device encounters hard objects when plowing the land, preventing damage to the device. A group of stirring teeth on the upper part of the spiral shaft not only stirs the fertilizer evenly, but also ensures that the fertilizer in the fertilizer bucket can be evenly transported to the bottom of each spiral shaft, ensuring that each spiral shaft can evenly transport fertilizer to the lower part. Each rotation of the spiral shaft will transport a fixed amount of fertilizer, ensuring uniform and quantitative fertilizer application. The speed of each spiral shaft can be changed by the speed regulator. Control the amount of fertilizer applied. When applying fertilizer, the plow seat and the vibration seat move under the soil. The hollow structure of the plow seat and the vibration seat can ensure that the spiral shaft transports the required fertilizer into the soil. When the No. 1 shaft rotates, the eccentric circle drives the vibration seat to swing up and down through the No. 1 connecting rod. The swinging vibration seat loosens the soil, loosens the soil, thickens the tillage layer, and provides sufficient growth space and nutrient sources for the crop roots, preventing soil compaction and restoring farmland. The core of deep plowing and fertilization is to push the fertilizer deep into the ground to allow the crop roots to better absorb nutrients. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] An operating method of a farmland restoration deep tillage device includes the following steps. When using the device, a motor vehicle is connected to the front of a front frame 110, fertilizer is added to a fertilizer bucket 129 on the upper part of a rear frame 120, and the motor vehicle pulls the device forward. Using the device is divided into the following steps. The first step is to adjust the fertilization depth. When adjusting, the lead screw 160 is rotated, and the lead screw 160 drives the nut 130 to move up and down. The nut 130 drives the rear frame 120 to move up and down. The rear frame 120 drives a group of fertilizer devices 300 to move up and down. The second step is to adjust the amount of fertilizer. The amount of fertilizer applied by each screw shaft 140 is controlled by adjusting the rotation speed of a speed regulator 170. After the adjustment is completed, a trial run is started to detect the fertilization depth and the amount of fertilizer applied. After the fertilization depth and the amount of fertilizer applied meet the requirements, normal fertilization is started.

[0027] The front frame 110 and the rear frame 120 connected by the No. 2 connecting rod 190 form a parallel connecting rod structure. The screw 160 is rotated to drive the nut 130, the rear frame 120, and the fertilizer device 300 to move up and down in parallel, so that the fertilizer device 300 connected to the rear frame 120 is always parallel to the ground, ensuring the consistency of the plowing depth of the fertilizer device 300. The screw screw 160 and the nut 130 connected with the thread can make the depth of the fertilizer device 300 entering the ground be finely controlled to ensure the required depth during fertilization. The spring 250 makes the front frame 110 and the rear frame 120 in a suspended state, which not only cushions the impact of the device when moving, but also provides a buffering force when the fertilizer device 300 encounters hard objects when plowing the land, thereby preventing the device from being damaged. A group of stirring teeth 140 on the upper part of the spiral shaft 140 1 It not only mixes the fertilizer evenly, but also ensures that the fertilizer in the fertilizer bucket 129 can be evenly transported to the bottom of each spiral shaft 140, ensuring that each spiral shaft 140 can evenly transport the fertilizer to the lower part. The spiral shaft 140 transports a fixed amount of fertilizer every time it rotates one circle, ensuring the uniform and quantitative fertilizer application. The amount of fertilizer application can be controlled by changing the rotation speed of each spiral shaft 140 through the speed regulator 170. When fertilizing, the plow seat 310 and the vibration seat 320 walk under the soil. The hollow structure of the plow seat 310 and the vibration seat 320 can ensure that the spiral shaft 140 transports the required fertilizer to the soil. When the No. 1 shaft 150 rotates, the eccentric circle 151 drives the vibration seat 320 to swing up and down through the No. 1 connecting rod 180. The swinging vibration seat 320 loosens the soil and prevents the soil from being compacted.
