Agricultural plant protection pest control and repelling device

Abstract

This invention provides an agricultural pest control and repellent device, relating to the field of agricultural protection. The device includes a soil-turning section and a flame-spraying section. The soil-turning section comprises multiple parallel plowshares that turn over the bottom layer of soil to the top, creating grooves that are subsequently covered by soil. The flame-spraying section includes an in-soil spraying end for spraying flames into the grooves created by the plowshares, and a surface spraying end for spraying flames onto the soil turned over by the plowshares. By changing the distance between adjacent plowshares and the interval between them, this device can, during the soil-turning process, first create grooves and keep them soil-free for a period. At this time, the in-soil spraying end heats the grooves, effectively killing insect eggs in the bottom layer of soil that has not yet been turned over. The surface spraying end then burns the turned-over soil, achieving a sustained high-temperature insecticidal effect from the soil.

Description

Technical Field

[0001] This invention relates to the field of agricultural protection, specifically to an agricultural plant protection pest control and insect repellent device. Background Technology

[0002] High-temperature flame soil sterilization is a technology for soil remediation and improvement. It involves heating the soil up to a depth of 30cm during rotary tillage using liquefied petroleum gas. A high-temperature flame sterilization and insecticidal machine is then used for sterilization and pest control. The soil exposure time is relatively short, with no impact on soil organic matter or nutrients. The soil temperature upon impact is typically 50-70℃, effectively killing root-knot nematodes with an efficacy rate exceeding 95%. It also has a significant killing effect on soil pathogens, bacteria, and weed seeds.

[0003] Existing patent CN119014391B describes a multi-stage inactivation method for soil rotary tillage followed by high-temperature chain-type contact sterilization using a throw-type flame jetting technique. This method includes the following steps: S1, machine start-up, adjustment, and forward movement; S2, initial flame sterilization; S3, secondary surface flame sterilization; S4, tertiary high-temperature contact sterilization; S5, quaternary high-temperature surface sterilization. This invention provides a novel inactivation method. This method not only involves four inactivation processes, improving the inactivation effect, but also provides a high-temperature chain-type contact sterilization method using a heat-conducting porous chain. The heated heat-conducting porous chain is dragged along with the advancing machine, disturbing and penetrating the soil surface for high-temperature sterilization. During the machine's movement, the contact area and contact time between the heat-conducting porous chain and the soil are increased, significantly improving the inactivation effect. This technical solution and similar solutions focus on sterilizing the surface soil, while the deeper soil layers are not sterilized during tillage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an agricultural plant protection pest control and insect repellent device, which solves the problem mentioned in the background technology that the soil sub-layer cannot be effectively treated.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an agricultural plant protection pest control and insect repellent device, comprising a soil turning section and a flame spraying section. The soil turning section includes multiple parallel plowshares. The plowshares enter the soil to turn the bottom soil to the top and create grooves, which are then covered by soil after a period of time. The flame spraying section includes a soil-entry flame spraying end for spraying flames into the grooves formed by the plowshares, and a surface flame spraying end for spraying flames onto the soil turned out by the plowshares.

[0006] Preferably, the plowshare is designed to flip the soil to one side, with the plowshares staggered front and back. A guide plate is provided at the tail end of the plowshare, which guides the flipped soil into a groove in the front plowshare. The guide plate is at a 30 to 40 degree angle to the direction of travel. The soil-penetrating flame-spraying end is located behind the connection between the guide plate and the plowshare. The surface flame-spraying end is divided into two groups: one group is located in front of the guide plate, and the other group is horizontally positioned at the tail end of the plowshare perpendicular to the direction of travel.

[0007] Preferably, the plow head uses a method of turning the soil to both sides, the plow head is a double-sided plow, and two adjacent plow heads are staggered front to back, with two adjacent plow heads overlapping halfway in the front-back direction. The soil-penetrating flame end is located at the rear end of the plow head, and the surface flame end is located behind the plow head.

[0008] Preferably, a flat soil plate is provided between the plow head and the surface flame-spraying end.

[0009] Preferably, the plow is provided with rotating soil-turning rollers on both sides and rear, and the surface flame-spraying end is provided with a set of flames that spray the turned soil.

[0010] Preferably, the plow is a horizontally rotating plow, with the soil-penetrating flame end located below the drive shaft connected to all plow heads and biased towards the side where the plow head enters the soil. A protective sleeve is rotatably connected to the outer surface of the drive shaft of the plow head, and the soil-penetrating flame end is sleeved inside the protective sleeve. The supply pipe of the soil-penetrating flame end is bent in the space to form a notch to allow the plow head to pass through when rotating. The surface flame end is located behind the plow head.

[0011] Preferably, the ignition tip ejects an excessive amount of combustible material that burns within the groove.

[0012] Preferably, the tail end of the flame jet is provided with a compaction section for compacting the soil.

[0013] Preferably, the surface flame-emitting end is periodically oscillated laterally by a control mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This agricultural plant protection pest control and insect repellent device, by changing the front-to-back distance between adjacent plowshares and the interval between adjacent plowshares, can, during the soil turning process, first open a trench and keep the trench free of soil for a period of time. At this time, the soil-penetrating flame end heats up the trench, thereby achieving the effect of burning and killing insect eggs in the bottom layer of soil that has not been turned up. After covering the trench with soil to keep it warm, the surface flame end burns and kills insect eggs in the turned-up soil, thereby achieving the effect of continuous high-temperature insect killing from the soil; 2. This agricultural plant protection pest control and insect repellent device, the front and back of the plowshares... The plowshare is staggered, with the front plowshare creating the groove first, and the rear plowshare turning the soil into the groove already created in the front. A guide plate is installed at the tail end of the plowshare to guide the movement of the turned soil. By adding the guide plate, the soil can move, and during this movement, any clumps will break up, making it easier to kill insects inside. The guide plate is at a 30-40 degree angle to the direction of travel. This angle allows the guide plate to guide the soil diagonally forward, and within this angle range, combined with the standard vehicle speed, it perfectly matches the effect of the soil being sprayed into the groove for disinfection and then covering the groove. 1. In this agricultural plant protection pest control and insect repellent device, the flame-spraying end sprays excessive combustible material into the groove for combustion. In this embodiment and the previous embodiment, the time between the formation of the groove and its covering with soil is relatively long. By spraying excessive combustible material into the groove, the combustible material can be fully burned within the groove space, thereby increasing the combustion time. After covering with soil, the bottom soil has already been heated and disinfected, and is covered by soil. The soil covering creates a uniform heating effect from top to bottom, which can prolong the heat dissipation time, thus keeping the soil in a high-temperature environment for a long time, which is conducive to pest control; 4. In this agricultural plant protection pest control and insect repellent device, the flame-spraying part The tail end is equipped with a compaction section for compacting the soil. By using the compaction section to compact the turned soil surface, the porosity between soil surfaces is reduced, preventing heat loss and thus increasing the heat preservation time. This more effectively kills insect eggs and ensures the overall aesthetics after the disinfect. 5. In this agricultural plant protection pest control and insect repellent device, the surface flame-spraying end swings periodically in the lateral direction through a control mechanism. The telescopic part and the return spring constitute the control mechanism, which makes the surface flame-spraying end reciprocate and extend. This allows the surface flame-spraying end to move and shift during the movement, avoiding concentrated heat and ensuring that the soil in other areas is not fully heated.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0029] like Figure 1 - Figure 4 As shown, an agricultural plant protection pest control device includes a soil-turning section 1 and a flame-spraying section 2, both connected to a frame. It can be self-propelled or towed. The control end and combustion supply of the flame-spraying section 2 are both located on the frame. The soil-turning section 1 includes multiple parallel plowshares 101. The plowshares 101 enter the soil, turning over the bottom layer of soil to the top and creating grooves, which are then covered by soil after a period of time. The flame-spraying section 2 includes a soil-entry flame-spraying end 201 for spraying flames into the grooves formed by the plowshares 101, and a flame-spraying end 201 for spraying flames onto the plowshares 101. The surface flame-spraying end 202 of the soil-turned-out flame can be used to heat the soil by changing the front-to-back distance between adjacent plowshares 101 and the interval between adjacent plowshares 101. During the soil-turning process, a trench can be opened first and kept empty for a period of time. At this time, the soil-entry flame-spraying end 201 can be used to heat the soil inside the trench, thereby achieving the effect of burning and killing insect eggs in the bottom layer of soil that has not been turned out. After the trench is covered with soil for insulation, the surface flame-spraying end 202 is used to burn and kill insect eggs in the turned-out soil, thereby achieving the effect of continuous high-temperature insect killing from the soil.

[0030] The plowshare 101 uses a method of turning soil to one side. There are two methods of turning soil to one side: one-way plowing and vertical rotary plowing. Both methods involve creating grooves and transferring the soil from the grooves to adjacent grooves. The plowshares 101 are staggered, allowing for staggered grooving times. The plowshare 101 at the front creates the groove first, and the plowshare 101 behind it turns the soil into the grooves created earlier. A guide plate 102 is located at the tail end of the plowshare 101. The guide plate 102 guides the movement of the turned soil. By adding the guide plate 102, the soil moves, and during this movement, clumps break up, making it easier to kill pests inside. The guide plate 102 directs the turned soil into the grooves created by the front plowshare 101. To increase the duration of soil flow within the guide plate 102 and extend the drying time, the plowshares 101 can be staggered. Divided into two groups, front and rear, the soil formed by the trenching is used to cover the grooves formed by the plowshare 101 through the guide plate 102. The guide plate 102 is at an angle of 30 to 40 degrees to the forward direction. By setting the angle, the guide plate 102 can guide the soil diagonally forward. At the same time, within this angle range, in conjunction with the standard vehicle movement speed, it perfectly meets the effect of soil being sprayed and disinfected in the groove and then filling the trench. The soil-filling spray end 201 is set behind the connection between the guide plate 102 and the plowshare 101. In this way, continuous trenching and continuous spraying can be carried out, and timely spraying and disinfection can be carried out after trenching. The surface spray end 202 is divided into two groups. One group is located in front of the guide plate 102, which can spray and disinfect the soil during the movement. The other group is set horizontally at the tail end of the plowshare 101 perpendicular to the forward direction. The surface spray end 202 at the tail end can spray and disinfect the soil over a large area, which is also the basis of the existing spraying and disinfection.

[0031] Taking the unidirectional plow shown in the attached diagram as an example, the existing unidirectional plow and fire-spraying disinfection device can be improved by first changing the position of the plow head 101, then adding a guide plate 102, then adding a soil-penetrating fire-spraying end 201 and a surface fire-spraying end 202 connected to the plow head 101, and finally combining the existing fire-spraying disinfection device and the soil-turning device. Finally, the supply pipes of all the fire-spraying ends are collected and connected. Through such a simple modification of the existing device, the effect of fire-spraying disinfection of deep soil can be achieved.

[0032] like Figure 5 - Figure 7As shown, in an alternative embodiment, the plow 101 adopts a method of turning the soil to both sides. The plow 101 is a double-sided plow, and two adjacent plow heads 101 are staggered front and back. The two adjacent plow heads 101 overlap halfway in the front-back direction. The soil-entry flame-spraying end 201 is located at the rear end of the plow head 101, and the surface flame-spraying end 202 is located behind the plow head 101. The advantage of using a double-sided plow is that it reduces the use of the guide plate 102. During the operation of the double-sided plow, the rear double-sided plow backfills the soil turned over by the front plow head 101 into its groove during the soil breaking process.

[0033] The in-soil flaming end 201 sprays excess combustible material into the groove for combustion. In this embodiment and the previous embodiment, the groove has a relatively long idle time from its formation to being covered by soil, and oxygen exists behind the formed groove. By spraying excess combustible material into the groove, the material may not burn completely upon spraying, but it still heats up initially. Then, it burns fully in the groove space with sufficient oxygen, achieving secondary heating. This increases the combustion time. After covering with soil, the bottom soil has already been heated and disinfected, and is covered by soil. The soil covering creates a uniform heating effect from top to bottom, which can extend the combustion time. The long heat dissipation time allows the soil to remain in a high-temperature environment for an extended period, which is beneficial for disinfection. However, the soil-penetrating flame-spraying end 201 and the surface flame-spraying end 202 need to be controlled separately. By controlling the gas supply through a gas valve, an excessive gas supply can be achieved by adjusting the gas supply ratio of the appropriate gas valve. The gas is then supplied to atomize the fuel and burn it at the port. When distributing fuel, the amount of fuel supplied is increased so that the fuel does not burn completely at the port. It drips into the groove and comes into contact with the air before completing the remaining combustion.

[0034] A flat soil plate 103 is provided between the rear plow head 101 and the surface flame end 202. During the process of turning over the soil with a double-sided plow, it is easy for the two plow heads 101 to form a bulge on the side that is close to each other. By setting up the flat soil plate 103, the soil can be smoothed out.

[0035] The plowshare 101 has rotating soil-turning rollers 104 on both sides and rear. The soil-turning rollers 104 are equipped with a ring of soil-turning shovels and are rotated as a whole through a transmission device and a central shaft. During the rotation, the soil is turned up, which allows the soil to fully contact the flame. The surface flame-spraying end 202 is equipped with a set of flames that spray onto the turned-up soil and sprays flames to both sides.

[0036] like Figure 8 and Figure 9As shown, in an alternative embodiment, the plow head 101 is a transverse rotary plow. The transverse rotary plow quickly enters and turns the soil, breaking it up during the turning process. However, the time to form grooves is relatively short, so it needs to be rotated and sprayed immediately. The soil-entry flame-spraying end 201 is located below the drive shaft connected to all plow heads 101 and is biased towards the side where the plow head 101 enters the soil. A protective sleeve 105 is rotatably connected to the outer surface of the drive shaft of the plow head 101. This ensures that the soil-entry flame-spraying end 201 always remains in a downward working state during the rotation of the plow head 101. The plow head 101 will pass through the flame zone below and heat up. There are two ways to solve this: one is to increase the rotation speed of the plow head 101 and reduce the contact time with the flame zone, so that the plow head 101 enters the soil and air for cooling as soon as it heats up. However, this cannot fundamentally solve the problem; prolonged heating of the plow head 101 will cause it to re-fire and soften. Furthermore, the rotation speed cannot be increased indefinitely; it needs to match the forward speed. The second solution is to use pulse ignition and pulse supply of combustible material at the soil-entry flame end 201. When the plow head 101 rotates to the flame zone, the supply of combustible material is turned off, and the supply of combustible material is restored and ignited after the plow head 101 passes through the flame zone. This can avoid the plow head 101, but it increases the cost of use. The choice can be made by considering the cost of using the plow head 101 and the cost of replacing the soil-entry flame end 201. The soil-entry flame end 201 is sleeved inside the sheath 105. The supply pipe of the soil-entry flame end 201 is bent in the space to form a gap to allow the plow head 101 to pass through when it rotates. By bending in the space, interference with the rotation of the plow head 101 can be avoided. It should be noted that when the plow head 101 is bent, it needs to be detected synchronously and collide with the supply pipe. The surface flame end 202 is set behind the plow head 101.

[0037] The tail end of the flame jet section 2 is provided with a compaction section 3 for compacting the soil. By using the compaction section 3 to compact the turned soil surface, the pores between the soil surfaces are reduced to prevent heat loss, thereby increasing the heat preservation time, more effectively disinfecting insect eggs, and ensuring the overall aesthetics after the disinfecting.

[0038] The surface flame-spraying end 202 oscillates periodically in the lateral direction through the control mechanism 4. The simplest way is to use a telescopic part and a return spring to form the control mechanism 4, so that the surface flame-spraying end 202 reciprocates and extends. This allows the surface flame-spraying end 202 to move and generate displacement to avoid concentrated heat, so that the soil in other locations is not fully heated.
