Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement equipment, and in particular to a push-type soil improvement equipment and a use method thereof. Background Art

[0002] Soil pollution, as a problem that restricts the sustainable development of human society, is increasingly receiving widespread attention from countries around the world. The main causes of soil pollution are excessive use of chemical fertilizers, improper disposal of various sewage, sludge and organic waste, and accidental discharge of harmful substances. When there are too many harmful substances in the soil, exceeding the self-purification capacity of the soil, it will cause changes in the composition of the soil, inhibit the production of microorganisms, and the harmful substances will eventually be indirectly absorbed by people, endangering their health. At present, the existing soil improvement method is to use liquid improvement solution to improve the soil, but when spraying the improvement solution, it is often the case that too much improvement solution is sprayed on the surface soil and too little improvement solution is sprayed on the bottom soil. This will cause uneven mixing of the soil and the solution, and will not have a good improvement effect;

[0003] In the existing patent CN108246786B, the solution to the uneven mixing problem is to provide a liquid spray hole on the main shaft equipped with soil crushing teeth, so that the liquid medicine can contact the underlying soil during the rotation process. However, this design still has the following problems:

[0004] 1. The spray holes on the main shaft are in close contact with the soil, so the soil may block the spray holes.

[0005] 2. There is still a distance between the axes. The soil near the axis is exposed to more liquid medicine, while the soil far from the axis is exposed to less liquid medicine, so there is still a problem of uneven mixing of the liquid medicine. Summary of the Invention

[0006] Therefore, the present invention is made in view of the above problems. The purpose of the present invention is to solve the problem of uneven mixing of liquid medicine and soil by using the cooperation of a rotary pushing device and a liquid spraying hole. The present invention achieves the above purpose through the following technical solutions:

[0007] A push-type soil improvement equipment and its use method, including: a shell, a rotary pushing device, a stirring device, and a motor. The shell includes: a soil inlet, a liquid spraying port, and a material discharge port. The upper end of the shell is provided with a soil inlet, and a plurality of groups of liquid spraying ports are provided on the side wall of the shell. A material discharge port is provided at the lower end of one side of the shell. The rotary pushing device includes: a soil storage bucket, a pushing blade, a transmission shaft, and a supporting plate. The lower end of the transmission shaft is connected to the output shaft of the motor. Three groups of supporting plates are provided on the transmission shaft and inside the shell. A soil storage bucket is penetrated on the three groups of supporting plates. Pushing blades are provided on the transmission shaft and at the upper end of the supporting plate. The soil storage bucket includes a discharging ring and a circular ring plate. The discharging ring is located on the outside of the soil storage bucket. A discharging blade is provided below the discharging ring and inside the soil storage bucket. There is a circular ring plate, and the pushing blade includes: a push plate, a scraper, a scraper groove, a spring, a movable plate, and a pushing blade circular hole. The push plate and the support plate are both located on the outside of the pushing blade circular hole, and the scraper and the push plate are staggered. A scraper groove is opened at the lower end of the scraper, and a spring is arranged inside the scraper groove. The upper end of the spring is fixedly connected to the inside of the scraper groove, and the lower end of the spring is fixedly connected to the movable plate. The lower end of the movable plate is an inclined surface, and the support plate includes: a small circular hole of the support plate, a large circular hole of the support plate, a high plate, a low plate, and a notch. The small circular hole of the support plate is connected to the drive shaft through a bearing. The notch is located at the junction of the high plate and the low plate, and the soil falls from here to the bottom. The stirring device is located below the lowest support plate, and the stirring device is fixedly connected to the drive shaft.

[0008] Preferably, three rows of liquid spraying ports are provided on the circumference of the shell, and each row of liquid spraying ports is provided with three liquid spraying ports. The pushing blades and the excavation ring are located in the same horizontal plane, and are evenly arranged in three layers up and down.

[0009] Preferably, the low plate and the high plate are an integrated structure, and the low plate is a certain distance lower than the high plate in the vertical direction.

[0010] Preferably, the stirring device is located below the lowest support plate, the stirring device is fixedly connected to the transmission shaft, the large circular hole of the support plate is fixedly connected to the soil storage bucket, and the high plate is located around the large circular hole of the support plate.

[0011] Preferably, the motor is provided with a device for changing the direction of the motor's working current. When in use, the user can change the direction of the motor's working current through the device for changing the direction of the motor's working current, thereby changing the direction of rotation of the motor.

[0012] Preferably, the soil storage bucket is made of stainless steel, and a detachable connector is directly provided between the soil storage bucket and the large circular hole of the support plate. When in use, the soil storage bucket can be separated from the large circular hole of the support plate by removing the connector.

[0013] A method for using a push-type soil improvement device, including the push-type soil improvement device described above, is specifically performed as follows:

[0014] Start the motor to drive the transmission shaft to rotate. At the same time, the stirring device and the pushing blades also rotate at the same time. The push plate rotates to push the soil in the soil storage bucket to the high plate. The push plate continues to rotate to the low plate. At this time, the soil falls on the low plate. The push plate rotates and pushes the soil so that the soil forms a thin layer on the low plate. At this time, the liquid medicine sprayed from the spray nozzle is mixed with the soil on the low plate. When the scraper rotates to the low plate, the moving plate inside the scraper groove pops out because there is no restriction from the high plate, so the moving plate can contact the soil mixed with the solution on the low plate, and then the soil is scraped to the notch and falls, falling on the stirring device below. After the material is fully stirred by the stirring device, it is output to the outside from the discharge port.

[0015] Beneficial effects of the present invention:

[0016] 1. There is a certain distance between the spray hole and the soil, so there will be no blockage;

[0017] 2. The present invention scrapes the soil into a thin layer by setting a rotating pushing device, and then sprays the liquid medicine from the spray holes of each layer. After the soil evenly mixed with the liquid medicine falls below, the stirring device stirs it again, so that the soil and the liquid medicine are fully mixed;

[0018] 3. The present invention has three layers of rotary pushing devices, which improves soil mixing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figure 4 As shown, the soil storage barrel 21 includes: an excavation ring 211 and a circular plate 212;

[0033] The excavation ring 211 is located on the circumference of the main body of the soil storage barrel 21, and is evenly arranged in three layers above and below. The annular plate 212 is immediately below the excavation ring 211. There are three annular plates 212, which are integrated with the soil storage barrel 21. The annular plates 212 assist the pushing blades 22 in pushing the soil outward.

[0034] like Figure 3 As shown, the pushing blades 22 and the excavation ring 211 are located at the same horizontal plane, and are evenly arranged in three layers above and below;

[0035] like Figure 5 As shown, the pushing blade 22 includes: a pushing plate 221, a scraper 222, a scraper groove 223, a spring 224, a moving plate 225, and a pushing blade circular hole 226;

[0036] The push plate 221 rotates to push the soil in the soil storage bucket 21 out, and the scraper 222 and the push plate 221 are arranged alternately. A scraper groove 223 is provided at the lower end of the scraper 222, and a spring 224 is provided inside the scraper groove 223. There are four springs 224, and the spring 224 is fixedly connected to the inside of the scraper groove 223. The movable plate 225 is located below the spring 224, and the movable plate 225 is fixedly connected to the spring 224. The movable plate 225 can move up and down in the scraper groove 223 due to the spring 224. The lower end of the movable plate 225 is an inclined surface, which facilitates the movable plate 225 to retract into the scraper groove 223 again. The pushing blade circular hole 226 cooperates with the transmission shaft 23, and the transmission shaft 23 drives the pushing blade 22 to rotate;

[0037] The support plate 24 is located below the push blade 22 and is also evenly arranged in three layers up and down, and is tightly connected to the push blade 22;

[0038] like Figure 6 As shown, the support plate 24 includes: a small support plate hole 241, a large support plate hole 242, a high plate 243, a low plate 244, and a notch 245;

[0039] The small circular hole 241 of the support plate is connected to the transmission shaft 23 by a bearing, so that the support plate 24 is stationary when the transmission shaft 23 rotates. The large circular hole 242 of the support plate is fixedly connected to the soil storage bucket 21. The high plate 243 is located around the large circular hole 242 of the support plate. The low plate 244 is integrated with the high plate 243. The low plate 244 is a distance lower than the high plate 243 in the vertical direction. The notch 245 is located at the junction of the high plate 243 and the low plate 244, and the soil falls from here to the bottom.

[0040] The stirring device 3 is located below the bottom support plate 24 and is fixedly connected to the transmission shaft 23. The transmission shaft 23 drives the stirring device 23 to rotate and stir the material.

[0041] The motor 4 is located below the stirring device 23 and provides power to the transmission shaft 23;

[0042] Among them, the motor 4 is provided with a device for changing the direction of the motor's working current. When in use, the user can change the direction of the motor's working current through the device for changing the direction of the motor's working current, thereby changing the rotation direction of the motor 4. The soil storage bucket 21 is made of stainless steel, and the soil storage bucket 21 has a detachable connector directly relative to the large circular hole 242 of the support plate. When in use, the soil storage bucket 21 can be separated from the large circular hole 242 of the support plate by removing the connector.

[0043] Working principle of the present invention:

[0044] The motor 4 is started, driving the transmission shaft 23 to rotate. At the same time, the stirring device 3 and the pushing blade 22 also rotate at the same time. The push plate 221 rotates to push the soil in the soil storage bucket 21 to the high plate 243. The push plate 221 continues to rotate to the low plate 244. At this time, the soil falls on the low plate 244. The push plate 221 rotates and pushes the soil so that the soil forms a thin layer on the low plate 244. At this time, the liquid sprayed from the liquid spraying port 12 is mixed with the soil on the low plate 222. When the scraper 222 rotates to the low plate 244, the movable plate 225 located inside the scraper groove 223 pops out due to the lack of the restriction of the high plate 243. Therefore, the movable plate 225 can contact the soil mixed with the solution on the low plate 244, and then the soil is scraped to the notch 245 and falls, falling on the stirring device 3 below. After the material is fully stirred by the stirring device 3, it is output to the outside from the discharge port 13.
