Description

Soil stirring disinfection device

Technical Field

The invention relates to the technical field of soil conservation, in particular to a soil stirring and sterilizing device.

Background

The modern planting industry is taken as an important foundation stone for the progress of human society and civilization, and the health and sustainable development of the planting industry are directly related to the global food safety, ecological environment balance and economic welfare of peasants. In this context, the importance of soil as a crop growing cradle is becoming increasingly pronounced. However, with the shift of agricultural production modes and the improvement of the intensive degree, the soil is facing unprecedented pressures and challenges, which threaten the yield and quality of cash crops and make serious test on the sustainable development of agriculture.

First, soil degradation is one of the greatest challenges facing the current planting industry. Although the land itself has a certain self-restoring ability and fertility preserving ability, the natural structure and ecological balance of the soil have been seriously damaged by long-term excessive cultivation, unreasonable irrigation and abuse of chemical fertilizers and pesticides. Excessive application of fertilizer, especially abuse of nitrogen fertilizer, causes accumulation of salt in soil, reduction of organic matters, compaction and hardening of soil structure, and reduction of permeability, which not only affects normal development of crop root systems and effective absorption of nutrients, but also aggravates risks of water and soil loss and soil erosion. Over time, soil fertility gradually decreases, and crop yield and quality also decrease, severely affecting sustainable development of agriculture.

Second, pest problems are also a non-negligible problem in commercial crop planting. In order to improve the yield and economic benefit of the cash crops, the planting density is often greatly improved, which provides an ideal breeding environment for pests. The rapid propagation of pests not only directly damages the health of crops, causes the damage of leaves and fruits, affects the yield and quality, but also often leaves a large number of pest eggs in the soil after the economic crops are harvested. These eggs will hatch rapidly under the appropriate conditions, becoming a potential threat to the next round of planting. The frequent occurrence and the difficulty of radical control of pests not only increase the use amount of pesticides and further aggravate soil pollution and ecological damage, but also increase the agricultural production cost and reduce the economic benefit. Meanwhile, the drug resistance of pests is continuously enhanced, so that the control effect of pesticides is gradually weakened, and vicious circle is formed.

Furthermore, imbalance of the soil microbial community is also a serious challenge to current planting industries. Soil microbial communities are key to maintaining ecological balance and promoting nutrient circulation. However, the structure and diversity of the soil microflora have been significantly changed due to the wide use of fertilizers and pesticides, the change of cultivation modes, and the difference of crop types and growth cycles. Some beneficial microorganisms are reduced or even disappear due to inadaptation to new environment, and some harmful microorganisms can be propagated while the machine is in use, so that the original ecological balance is broken. The change of the microbial community not only affects nutrient absorption and stress resistance of crops, but also can aggravate the occurrence of soil-borne diseases, and further threatens the planting benefit and sustainable development of economic crops. In addition, imbalance in the soil microflora may also affect the maintenance and restoration capacity of soil fertility, making the soil more vulnerable and susceptible to degradation.

Meanwhile, in the running process, the power motor is synchronously started, so that the conveyor belt is driven to continuously rotate. As the soil gradually builds up, eventually the soil moves to the conveyor belt. Under the continuous driving of the conveyor belt, the soil is gradually crushed, and the crushed soil passes through the conveyor belt and falls on the ground again through the sterilizing plate. On the other hand, in the advancing process of the device, the high-pressure complete machine generating device continuously generates high-temperature steam, and the high-temperature steam is transmitted to the sterilizing plate through the pipeline.

Compared with the prior art, the invention has the following advantages:

The soil spade 11 is inserted into the soil layer in the process of being towed by the agricultural equipment, so that the soil on the towing path is continuously spaded up. The scooped up soil gradually builds up on the shovel 11. At the same time, the power motor 13 is in an operational state, i.e. the conveyor belt 12 is continuously rotating. When soil of the shovel 11 is piled up on the conveyor belt 12, the stirring protrusions 1211 on the links 121 continuously hit the soil due to the continuous rotation of the conveyor belt 12, thereby breaking up the agglomerated soil. On the other hand, hard lumps such as hard agglomerates and stones in the soil are pulled out by the pulling protrusions 1211, so that the hard lumps are finally thrown into the collecting box 14 under the driving of the conveyor belt 12, and the collection of the hard lumps is completed. Therefore, the invention can effectively break up the caked soil and collect the hard lumps in the soil at the same time, thereby facilitating the growth of the root systems of subsequent cash crops.

When the soil is crushed, the crushed soil passes through the conveyor belt 12 through the gaps between the links 121 and falls to the ground through the gaps between the sterilizing boards 22. Therefore, in the process of traveling, the high-pressure high-temperature steam generated by the high-pressure steam generating device 21 can be continuously output through the output port on the sterilizing plate 22, so that the crushed soil is sterilized at high temperature, eggs, bacteria and fungi in the soil are killed, and further the growth of subsequent economic crops is facilitated.

Because the soil has been broken up by the conveyor belt 12, the contact between the soil and the water vapor is more sufficient, so that the disinfection time of the soil can be shortened to a certain extent, and the operation efficiency of the device can be improved to a certain extent.

Detailed Description

The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

A soil stirring and sterilizing device comprises a soil stirring device 1, a sterilizing device 2 and an assembling bracket 3. The shape of the assembly bracket 3 is matched with the soil turning device 1 and the disinfection device 2, so that the soil turning device 1 and the disinfection device 2 can be fixedly assembled together. Specifically, the soil turning device 1 comprises a soil spade 11, a conveyor belt 12, a power motor 13, a collecting box 14, a transmission structure 15 and a discharging cylinder 16. Conveyor belt 12 includes links 121. The number of links 121 is plural. The links 121 enclose a closed loop. Links 121 are rotatably connected. A gap is provided between adjacent two links 121. Meanwhile, a toggle protrusion 1211 is provided on the link 121. Toggle projection 1211 is fixedly coupled to link 121. The protruding direction of the toggle projection 1211 is perpendicular to the moving direction of the link 121. The transmission structure 15 includes a transmission rod 151, a transmission gear 152, and a chain 153. The transmission rod 151 is rotatably connected with the assembly bracket 3. The number of the transmission rods 151 is two. The transmission rods 151 are parallel. One of the transmission rods 151 is assembled to a higher level than the other transmission rod 151, so that the connection line between the two transmission rods 151 forms an inclined oblique line. The transmission gear 152 is fixed to an end of the transmission rod 151. Thus, when the transmission gear 152 rotates, the transmission rod 151 can be driven to rotate synchronously. On the other hand, the arrangement of the teeth on the drive gear 152 matches the spacing between the links 121 so as to be able to mesh with the conveyor belt 12. Thus, when the conveyor belt 12 is sleeved on the transmission rods 151 through the transmission gears 152, the two transmission rods 151 are respectively located at two ends of the conveyor belt 12, and the transmission gears 152 respectively correspond to the four apex angle ends of the conveyor belt 12. Thus, the conveyor belt 12 is inclined as a whole. Meanwhile, an auxiliary gear is fixedly arranged on one of the transmission gears 152, one end of the chain 153 is sleeved on the auxiliary gear, and the other end is sleeved on the output end of the power motor 13. Thereby, the power motor 13 can drive the corresponding transmission gear 152 to rotate through the chain 153.

The shovel 11 is fixedly connected with the assembly bracket 3. The shovel 11 rests at the lower end of the conveyor belt 12. The shovel 11 is provided with an inclined slope. The inclination angle of the inclined slope matches the inclination angle of the conveyor belt 12. Thereby, the shovel 11 can be fitted with the conveyor belt 12. The end of the shovel 11, which is far away from the conveyor belt 12, is also fixedly provided with shovel teeth. The number of the shovel teeth is multiple. The cutting teeth are evenly distributed from one side of the shovel 11 to the other side.

The collecting box 14 is fixedly connected with the assembly bracket 3. The collection box 14 is fixedly connected with one end of the conveyor belt 12 far away from the shovel 11. The collection box 14 is provided with a discharge flap 141. The discharge flap 141 is provided on the side of the collection box 14 close to the ground. The discharge flap 141 is rotatably connected to the collection box 14. The end of the discharge cylinder 16 is rotatably connected to the mounting bracket 3. The output end of the discharge cylinder 16 is rotatably connected with the discharge flap 141. Thus, when the discharging cylinder 16 is operated, the discharging turning plate 141 is driven to turn over, so that the collecting box 14 is opened or closed. Meanwhile, through the foregoing assembly relationship, the conveying direction of the conveyor belt 12 is directed from the shovel 11 to the collection box 14.

The sterilizing device 2 comprises a high-pressure steam generating device 21 and a sterilizing plate 22. The high pressure steam generating means 21 is in communication with a sterilizing plate 22. Sterilizing panel 22 is fixedly disposed on the side of conveyor 12 adjacent the floor. The steam output of the sterilizing panel 22 is directed towards the surface. On the other hand, the number of the sterilizing panels 22 is plural. A gap is provided between the sterilizing plates 22.

Meanwhile, the travelling wheel 31 is also arranged on the assembly bracket 3. The travelling wheel 31 is rotatably connected with the mounting bracket 3. The travelling wheel 31 is arranged at the end of the mounting bracket 3 remote from the shovel 11.

The device is fixedly connected with other existing agricultural equipment in advance, such as a tractor. Specifically, one end of the connecting rod can be fixedly connected with the assembly bracket 3, and the other end of the connecting rod is fixedly connected with the tractor. Thus, when the agricultural equipment travels, the device can be driven to travel synchronously through the travelling wheel 31.

In practical application, one end of the shovel 11, which is fixedly provided with shovel teeth, is inserted into soil. Thus, when the agricultural equipment drives the device to travel, the soil spade 11 continuously scoops up the soil and gradually pushes the soil to the conveyor belt 12 along with the travelling process. Meanwhile, the power motor 13 is in a start state. The chain 153 is continuously rotated under the driving of the power motor 13, so that the corresponding transmission gear 152 is driven to rotate. The transmission rod 151 and the conveyor belt 12 are synchronously rotated under the drive of the transmission gear 152.

During the rotation of the conveyor belt 12, the stirring protrusions 1211 on the conveyor belt 12 continuously stir the soil, thereby breaking up the agglomerated soil. Meanwhile, the hard blocks and the broken stones in the soil continuously move along the conveyor belt 12 under the driving of the stirring protrusions 1211. Finally, the aforementioned debris moves to the other end of the conveyor belt 12 under the continuous drive of the conveyor belt 12, and thus enters the collection box 14. Meanwhile, the crushed soil falls through a gap between adjacent two chains 153. Eventually, the crushed soil falls through conveyor 12 to a sterilizing panel 22. Since gaps are also provided between the sterilizing boards 22, soil falls to the ground through the gaps between the sterilizing boards 22. On the other hand, in the foregoing process, the high-pressure steam generating means 21 is synchronously activated, so that high-pressure steam is continuously generated, and the generated high-pressure steam is transferred to the sterilizing panel 22 through the duct. Finally, the output is through an output port on the sterilizing panel 22. Because the output direction of the sterilizing plate 22 faces the ground, the sterilizing plate 22 can sterilize the smashed soil in the travelling process of the device, so that the high-temperature steam is utilized to kill eggs, bacteria and fungi in the soil. On the other hand, because the soil has been smashed, then the contact of soil and steam is more abundant to reduce to a certain extent and disinfect the time for soil, promoted the operating efficiency of this device.

After a certain distance, the collection tank 14 is gradually filled. At this point, the transport vehicle or other equipment is aligned with the bottom of the collection bin 14 and the discharge cylinder 16 is activated. The output end of the discharge cylinder 16 is contracted, so that the discharge flap 141 is driven to turn over relative to the collection box 14, and the bottom of the collection box 14 is opened. At this time, the foreign matters collected in the collection box 14 are discharged. Subsequently, the discharging cylinder 16 is started again, and the output end of the discharging cylinder 16 extends out, so that the discharging turning plate 141 is driven to reversely turn over relative to the collecting box 14, and the bottom of the collecting box 14 is closed. Therefore, the device can be driven to travel again through agricultural equipment.

In summary, the present invention is configured such that the shovel 11 is inserted into the soil layer during the towing by the agricultural equipment, thereby continuously scooping up the soil on the towing path. The scooped up soil gradually builds up on the shovel 11. At the same time, the power motor 13 is in an operational state, i.e. the conveyor belt 12 is continuously rotating. When soil of the shovel 11 is piled up on the conveyor belt 12, the stirring protrusions 1211 on the links 121 continuously hit the soil due to the continuous rotation of the conveyor belt 12, thereby breaking up the agglomerated soil. On the other hand, hard lumps such as hard agglomerates, stones, etc. in the soil are pulled out by the pulling protrusions 1211 (the size of the hard lumps is larger than the gap between the adjacent two links 121). Thus, the hard lumps are finally thrown into the collection box 14 under the drive of the conveyor belt 12, and the collection of the hard lumps is completed. Therefore, the invention can effectively break up the caked soil and collect the hard lumps in the soil at the same time, thereby facilitating the growth of the root systems of subsequent cash crops.

On the other hand, when the soil is crushed, the crushed soil passes through the conveyor belt 12 through the gaps between the links 121, and then falls to the ground through the gaps between the sterilizing boards 22. Therefore, in the process of traveling, the high-pressure high-temperature steam generated by the high-pressure steam generating device 21 can be continuously output through the output port on the sterilizing plate 22, so that the crushed soil is sterilized at high temperature, eggs, bacteria and fungi in the soil are killed, and further the growth of subsequent economic crops is facilitated.

Secondly, because the soil has been broken by the conveyor belt 12, the contact between the soil and the water vapor is more sufficient, so that the disinfection time of the soil can be shortened to a certain extent, and the operation efficiency of the device can be improved to a certain extent.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention.
