Abstract
Description
Technical Field
[0001] The utility model relates to the field of hybrid hazelnut cultivation tools, in particular to a chemical tillering device for hybrid hazelnut trees and an integrated application system thereof. Background Art
[0002] Hazelnut is a plant of the genus Corylus in the Betulaceae family. It is one of the four famous nuts. It is rich in nutrition and has high economic value. It has long been favored. After years of hybridization and breeding, artificial seedling breeding and large-scale cultivation have been achieved. Hybrid hazelnut trees are prone to produce root suckers and sprouts during their growth. The so-called root suckers and sprouts refer to branches or buds growing from the rhizomes and the base of the plant, respectively. Although this characteristic is conducive to the asexual reproduction of hybrid hazelnut trees, it will cause the tree's nutrients to disperse during the development and growth process, which is not conducive to the flowering and fruiting of hybrid hazelnut trees. In severe cases, it will also lead to a significant reduction in hazelnut yields, so regular tillering must be carried out during the planting and management process. At present, there are two main methods for removing tillers of hybrid hazelnut trees: manual tillering and chemical tillering. Manual tillering is to remove tiller branches and tiller buds by hand pruning, which has high labor intensity and low operation efficiency. It needs to be pruned many times during the growing season, resulting in increased production costs. In actual production, chemical tillering is usually used. Chemical tillering kills root tillers or sprouts by spraying tillering agents, which has high efficiency and good effects. However, the operating procedures based on the characteristics of tillering agents are very strict. Tillering agents cannot be sprayed on the main branches, stems and leaves of hybrid hazelnut trees and the bodies of operators to avoid affecting the tree. The normal development of trees is harmful to human health, while hazelnut belongs to shrubs or small trees, the tree body is short and has no obvious trunk and is in a clump growth form, and the roots are mostly covered by dense branches and leaves. During the chemical tillering process, the covering and blocking of the tillering herbicide not only prevents it from being fully and efficiently sprayed on the root tillers or sprouts, reducing the tillering effect, but also makes it inevitable to spray on the covered branches and leaves and easily blocked by the covered branches and leaves, refracted and splashed on the main branches, stems and leaves or human bodies, destroying the normal growth of trees, causing physical injuries to people, and obvious hidden dangers in production safety. Therefore, it is necessary to study and develop a special agent spraying device for chemical tillering of hybrid hazelnut trees, improve the safety and reliability of tillering operations, and enhance the efficiency of tillering operations. Utility Model Content
[0003] The purpose of the utility model is to provide a chemical tillering device for hybrid hazelnut trees and an integrated application system thereof, which is specially used for safely and efficiently spraying tillering agents on root tillers or sprout tillers of hybrid hazelnut trees, thereby solving the problems of the prior art.
[0004] A chemical tillering device for hybrid hazelnut trees, comprising: a structural box, a stretching rod, a liquid flow pump, a guide pipe, an atomizing nozzle, a solenoid valve and a hydraulic sensor, wherein the structural box is a housing, a carrying handle is arranged on the outside of the housing, and the liquid flow pump is accommodated and fixedly installed inside the housing, the stretching rod is a rigid rod body with a central axis hole, one end of which is hingedly connected to the structural box so that the stretching rod can swing relative to the structural box at the hinge point as the axis, and the atomizing nozzle is connected and installed on the other end, and a control handle is arranged on the outside of the rod body, the solenoid valve is a normally closed one-way valve, which is embedded in the central axis hole of the stretching rod and connected to the atomizing nozzle in cooperation, the hydraulic sensor is a ring structure, which is installed in cooperation on the liquid outlet of the liquid flow pump, the guide pipe is a pressure-bearing non-metallic pipe, and a layout device is arranged on the central axis of the stretching rod. In the hole, the upper end is the drainage end, which is connected to the hydraulic sensor to introduce the tillering agent from the liquid flow pump, and the lower end is the spraying end, which is connected to the solenoid valve to guide the tillering agent, so that the diversion tube can be connected with the discharge port of the liquid flow pump through the hydraulic sensor at the drainage end, and at the same time, it can be connected with the atomizing nozzle through the solenoid valve at the spraying end. The hydraulic sensor can instantly detect the liquid flow pressure of the tillering agent flowing into the diversion tube. When the liquid flow pressure reaches a preset pressure limit value, the solenoid valve can be opened by the control circuit to connect the diversion tube with the atomizing nozzle. The tillering agent in the diversion tube can be pressurized and discharged through the atomizing nozzle to prevent the tillering agent from generating low-pressure seepage and ensure the atomization effect of the tillering agent being discharged.
[0005] The chemical tillering device for hybrid hazelnut trees is preferably provided with a protective cover connected to both the extension rod and the mounting end of the atomizing nozzle. The protective cover is made of elastic rubber material and is arranged corresponding to the atomizing nozzle. The atomizing nozzle is covered in the protective cover so that the protective cover can be sealed with the ground to form a protective space when placed flat on the ground. The protective space can concentrate and seal the atomized liquid flow of the tillering agent guided through the atomizing nozzle to prevent the atomized liquid flow from splashing and spreading outside the protective cover.
[0006] The chemical tillering device for hybrid hazelnut trees is preferably provided with a corrugated connecting sleeve on the protective cover, and the protective cover is connected to the stretch rod through the corrugated connecting sleeve. The multi-directional deformation ability of the corrugated connecting sleeve can significantly improve the spatial adaptability between the protective cover and the stretch rod, so that the protective cover can always cooperate with the ground to maintain a sealed state when the spatial orientation of the stretch rod dynamically changes, thereby fully ensuring the sealing effect of the atomized liquid flow of the tillering agent.
[0007] The chemical tillering device for hybrid hazelnut trees further includes: an elastic load-bearing rod, which is a structural straight rod body that is axially elastically retractable and connected to the lower end of the structural box in a detachable manner, and a universal roller is installed on the lower end. When bearing and supporting the structural box, the overall weight of the structural box can cause the elastic load-bearing rod to contract, and the magnitude of contraction can meet the process requirements for adjusting the height of the structural box. On this basis, the elastic reaction force generated by the elastic load-bearing rod relative to the structural box can partially offset the gravity of the structural box, reducing the vertical force required for the operator to carry or lift the structural box. At the same time, the universal roller can ensure the smoothness and stability of the horizontal movement of the elastic load-bearing rod while maintaining continuous bearing and supporting the structural box.
[0008] In the chemical tillering device for hybrid hazelnut trees, the liquid flow pump is preferably an electric diaphragm pump. The electric diaphragm pump has compact functional structure, outstanding self-priming ability, precise flow delivery, and good adaptability to a wide range of fluids. This ensures efficient matching and integration of the electric diaphragm pump with other components, optimizes the overall structure of the chemical tillering device for hybrid hazelnut trees, and improves functional efficiency. Moreover, the transmission of the tillering agent is not limited by the height of the supply liquid level, and can ensure the continuous and stable flow of the tillering agent, achieve precise control of transmission, and provide process guarantee for the quantitative spraying of the tillering agent. At the same time, its excellent corrosion resistance is also conducive to ensuring the safe operation of the chemical tillering device for hybrid hazelnut trees, improving its service life, and ensuring the stability and reliability of its operation.
[0009] The invention discloses an integrated application system of a chemical tillering device for hybrid hazelnut trees, comprising: a loading container and a chemical tillering device. The chemical tillering device is the chemical tillering device for hybrid hazelnut trees. The loading container is a container for holding a tillering agent, which can be loaded and transferred by a carrier. A plurality of diversion holes are provided on the loading container, and diversion pipes are respectively connected to the diversion holes. The other end of the diversion pipe can be matched and connected with the liquid inlet hole of the liquid flow pump on the chemical tillering device, so that the liquid flow pump and the loading container are interconnected and can obtain the tillering agent from the loading container. After the connection, the chemical tillering device can perform tillering operations on hybrid hazelnut trees at a remote end relative to the loading container, greatly increasing the radiation range of the tillering agent provided by the loading container, eliminating the subpackaging operation process of the tillering agent, shortening the moving distance of the loading container, and effectively improving the efficiency of the tillering operation and reducing the labor intensity of the operation.
[0010] The beneficial effect of the utility model is to provide a chemical tillering device for hybrid hazelnut trees, which adopts an independent portable structure and centrally delivers tillering agents from a remote end. It has the characteristics of simple structure, easy operation, safety and high efficiency. The extension rod can be used to eliminate obstacles of branches and leaves, and the atomizing nozzle can be accurately positioned to the position of the tillering or root tillering, avoiding the covering and blocking of the atomizing nozzle by branches and leaves and the blocking and refraction of the tillering agent. The pressure-controlled atomizing spraying agent by an electric control valve can improve the atomization effect, reduce the spatial diffusion loss and low-pressure overflow loss of the tillering agent, realize the controllable spraying of the tillering agent at a fixed point and in a fixed quantity, ensure that the tillering agent can be fully and efficiently sprayed on the root tillers or sprouts of the hybrid hazelnut trees, improve the tillering efficiency, save the tillering agent, and improve The tillering effect is improved and safety hazards are reduced. Furthermore, the preferred use of an electric diaphragm pump and a matching protective cover can effectively enhance the overall use function of the chemical tillering device; on this basis, several sets of chemical tillering devices are integrated with loading containers loaded with tillering agents to form an integrated application system of chemical tillering devices for hybrid hazelnut trees. In forestry production, the packaging operation process of the tillering agent can be omitted, the transportation distance of the loading container can be shortened, and the labor intensity of the operators can be reduced. In particular, the large-capacity loading container can provide the tillering agent to multiple sets of chemical tillering devices over a long distance, and the operating radiation range of the system can be greatly increased, which can significantly reduce the production cost of tillering operations in forest areas, improve the operation production efficiency, and promote the improvement and transformation of forestry production methods.

[0020] The chemical tillering system for hybrid hazelnut trees described in this embodiment is used in the production of hybrid hazelnut trees. The specific process method is as follows: fill the loading container 10 with a tillering agent, safely close the loading container 10, and then use a carrier 14 to transport the loading container 10 to a tillering operation area within the planting range of the hybrid hazelnut trees, so that the loading container 10 is located at the center of the tillering operation area, and connect the number of chemical tillering devices 15 to be used to the loading container 10 respectively, and open the corresponding diversion holes on the loading container 10, so that the loading container 10 is connected to each of the chemical tillering devices 15; thereafter, the operator can use the chemical tillering devices 15 at different positions within the radiation range of the loading container 10. The tillering operation is performed on the tree, and the farthest distance of the tillering operation can reach the area where the shunt pipe 16 is fully extended. During the specific operation, the operator can keep a certain distance from the target hazelnut tree, use the stretching rod 2 to move the branches of the target hazelnut tree, observe and find the tillers or root tillers to be removed, and after finding the tillers or root tillers, buckle the protective cover 8 at the front end of the stretching rod 2 on the tillers or root tillers, cooperate with the control handle 11 and the control handle 12 to adjust the spatial posture of the stretching rod 2 so that the protective cover 8 forms a good sealing match with the ground, and then use the fingers of the holding hand on the carrying handle 11 to press the elastic key switch 18 set on the carrying handle 11 to instantly connect the control circuit on the control circuit board 17. In the control circuit, Figure 5As shown, the connection of the contact switch S causes the relay coil KT1 to be powered on and triggers the relay contact switch K1 to be connected. After the contact switch S is disconnected, the control circuit can continue to be connected because the relay contact switch K1 is connected. At this time, the liquid flow pump PUMP and the hydraulic sensor P are respectively turned on, that is, the electric diaphragm pump and the hydraulic sensor 7 are started and run at the same time. The electric diaphragm pump transports the tillering agent into the guide pipe 4. When the liquid flow pressure of the tillering agent in the guide pipe 4 reaches the pressure limit When the value is set, the hydraulic sensor P triggers the sensor contact switch KP to close, so that the electromagnetic valve YV and the relay coil KT2 are turned on, and the electromagnetic valve YV, that is, the electromagnetic valve 6, is powered on and opened, so that the guide tube 4 is connected with the atomizing nozzle 5, and the tillering agent with a limited pressure value in the guide tube 4 is atomized and sprayed from the atomizing nozzle 5, and the sprayed tillering agent is completely sealed in the protective cover 8. At the same time, the relay coil KT2 triggers the relay contact switch K2 to disconnect after the delay time T, that is, after the atomizing nozzle 5 sprays for the delay time T, the main circuit of the control circuit is disconnected, the liquid flow pump PUMP stops working, the electromagnetic valve YV is powered off and closed, and the hydraulic sensor P, the relay coil KT1 and the relay coil KT2 are powered off to reset the sensor contact switch KP and the relay contact switch K1 to open, and the relay contact switch K2 to close, and the control circuit returns to the initial basic circuit. In the connection state, the solenoid valve 6 returns to the initial closed structure state. In the above process, since the solenoid valve 6 is controlled to open the delay time T, the spraying amount of the tillering agent on the tiller or root tiller is accurately controlled, and the spraying effect and use efficiency of the tillering agent are optimized. At this point, the spraying operation of the tiller or root tiller at each point is completed, and thereafter the spraying operation can continue to be performed sequentially on the tiller or root tiller at different points until all tillering operations are completed.
[0021] During the tillering removal operation according to the above-mentioned process method, if there are a large number of sprouting tillers or root tillers in a certain local area and the points that need to be sprayed are relatively dense, in order to reduce the physical exertion of the operator in carrying the structural box 1, the elastic load-bearing rod 9 can be installed at the lower part of the structural box 1 at any time, and the elastic support effect of the elastic load-bearing rod 9 can be used to share the weight of the structural box 1, thereby reducing the force required for the operator to carry the structural box 1, reducing labor intensity, and improving work efficiency.
