Description

Technical Field

[0001] This utility model belongs to the field of agricultural implements technology, and in particular relates to a field isolation device for the batch configuration of chemically sterilized hybrid combinations of rapeseed. Background Technology

[0002] Chemical emasculation (or simply chemical emasculation) technology overcomes the drawbacks of cumbersome manual emasculation and the long cycle of converting sterile lines. With its advantages such as wide availability of parental sources, absence of adverse cytoplasmic effects, freedom of mating, and stable male sterility, it has gradually become one of the superior systems for utilizing heterosis in rapeseed and is now widely used in rapeseed hybrid breeding and seed production. Chemical emasculation selectively inhibits anther development by spraying chemical agents, preventing the plant from producing pollen or producing inactive pollen. Although the ovules develop normally, they cannot self-pollinate and must rely on external pollen for pollination. In rapeseed hybrid breeding, its core functions include: efficient emasculation; using chemical agents (such as zinc methylarsenate and copper sulfate) to precisely inhibit anther development or pollen viability, creating sterile lines, i.e., the female parent of hybrid combinations, avoiding the cumbersome operation of manual emasculation, and significantly improving the efficiency of hybrid combination preparation and hybrid seed production. Especially in the hybrid combination screening stage, chemical control can quickly verify the combining ability between fertile parents, accelerating the screening process for heterotic combinations. Currently, in the process of formulating and screening chemically controlled hybrid combinations in rapeseed, to facilitate the production of the first generation F1 hybrids, the parent plants of the chemically controlled combination are planted alternately in the field. Both are fertile, and chemical control agents need to be sprayed in the field in the early budding stage to kill the male reproductive organs of the female plant. The flowering period of the chemically controlled female plant is then combined with the flowering period of the adjacent male plant in a hybridization bag, thereby achieving rapid formulation of chemically controlled hybrid combinations and efficient production of F1 hybrids. Due to the large number of planting materials in the field, the chemically controlled female plant requires manual assistance to set up physical barriers to achieve precise chemical spraying of individual materials and avoid affecting the normal development of pollen from adjacent male plants. In this operation, the traditional method relies on multiple people working together to continuously move multiple simple physical barriers, which seriously affects the implementation efficiency of chemical control operations. At the same time, the physical barriers used by multiple people are not very airtight, and there is a risk of chemical reagent leakage. Therefore, this invention designs a tightly isolated and movable device that allows a single person to complete the chemical disinfection operation, which can significantly improve the efficiency of chemical disinfection while avoiding environmental pollution and the harm of chemical disinfectants to the operator's body. Utility Model Content

[0003] The purpose of this invention is to solve the risk of chemical reagent leakage and spillage in the prior art.

[0004] To achieve the above objectives, this utility model proposes a field isolation device for the batch configuration of chemically emasculated hybrid combinations in rapeseed. The device includes a mobile frame, which is a rectangular box formed by four track columns, two vertical rods, and four horizontal rods connected together. The bottom of the mobile frame is open. Each track column has a track groove on its adjacent two sides. The top, front, rear, left and right ends of the mobile frame are all equipped with box-shaped linings. The top box-shaped lining is fixed to the mobile frame. The two ends of the front and rear box-shaped linings are connected to the track grooves of the track column. The two ends of the left and right box-shaped linings are slidably connected to the track grooves. The front end of the mobile frame has a medicine inlet on the lining of the box. Roller boxes are installed on the top crossbars at the left and right ends of the mobile frame. The two ends of the roller are rotatably connected to the left and right side walls of the roller box through ball bearings. The roller is fixedly connected to the top edge of the box lining. The roller pull line is installed on the ball bearing, and the roller pull line is equipped with balls that match the ball bearing. The top, front, rear, left and right sides of the mobile frame are provided with guide grooves, and the bottom of the inner side of the inner side of the box is provided with a liquid receiving groove, which is a rectangular groove. The bottom of the mobile frame is equipped with casters.

[0005] Furthermore, the diameter of the inlet hole is 5-10cm, the inlet hole is circular, and its inner side is provided with an extended soft plastic sleeve.

[0006] Furthermore, the track groove extends along the length of the track column.

[0007] Furthermore, the roller box is driven by roller cables to move the left and right end housings up and down within the track groove.

[0008] Furthermore, a spring top ball is installed on the inner wall of the roller box at the position corresponding to the toothed ball bearing to restrict the rotation of the outer ring of the bearing.

[0009] Furthermore, the guide channel is a semi-cylinder with a diameter of 0.5cm.

[0010] Furthermore, the liquid receiving tank is positioned corresponding to the bottom end of the guide channel, and is used to receive the liquid flowing down through the guide channel.

[0011] Furthermore, casters are installed at the four corners of the bottom of the mobile frame.

[0012] The beneficial effects of this utility model are as follows: 1. This application utilizes casters mounted on the bottom of the mobile frame, enabling flexible single-person movement of the device without the need for multiple people to assist in transporting it. It allows for rapid transfer between different planting rows in the field. The side panels of the mobile frame's left and right ends, connected to roller boxes and roller cables via track grooves, allow for convenient height adjustment of the side panels without manual disassembly or partition construction. A single person can perform the raising and lowering of the side panels and the positioning of the device. It is compatible with hybrid planting patterns using two rows as units, allowing one spray to cover two rows of plants, reducing the number of device movements and significantly shortening the time required for single-group chemical control. This design allows a single person to independently complete the entire chemical control process, greatly reducing manpower requirements and significantly improving efficiency compared to traditional multi-person operation methods. Furthermore, this device has a simple structure and is easy to operate.

[0013] 2. The mobile frame adopts a five-sided enclosed rectangular box structure. The top, front, rear, left, and right ends are all equipped with box linings, forming a completely enclosed space to prevent pesticide drift. The inner side of the inlet hole in the front lining is designed with an extended, soft plastic sleeve that tightly fits the sprayer rod, eliminating gaps at the orifice and preventing pesticide leakage from the operating channel. A semi-cylindrical guide channel is set on the inner side of the lining to guide pesticide drifting onto the lining surface to a rectangular collection tank at the bottom for centralized collection, preventing pesticide dripping and contamination of adjacent male parent plants or soil. Through this design, the drift and leakage rate of chemical pesticides is reduced, effectively ensuring the normal development of pollen from adjacent male parent materials, improving the yield and purity of the first generation F1 hybrids, while simultaneously avoiding the health hazards to operators from pesticide drift.

[0016] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0017] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] Please see Figures 1-3A field isolation device for the batch configuration of chemically emasculated hybrid combinations for rapeseed includes a mobile frame 1. The mobile frame 1 is a rectangular box consisting of four track columns 5, two vertical rods, and four horizontal rods connected together, capable of accommodating crops. The bottom of the mobile frame 1 is open, and the top, front, rear, left, and right ends of the mobile frame 1 are all equipped with box enclosure fabric 6.

[0019] Each track post 5 has a track groove 10 on its adjacent two sides. The design of two track grooves 10 fixes the surrounding cloth of the box body, so that the two adjacent cloth pieces do not interfere with each other. On the one hand, it makes the cloth more stable and less prone to shaking. On the other hand, the track grooves 10 extend along the length of the track post 5, which can also realize the free adjustment of the height of the cloth.

[0020] The box-shaped lining 6 at the top of the mobile frame 1 is fixed to the mobile frame 1; the two ends of the box-shaped lining 6 at the front and rear ends of the mobile frame 1 are connected to the track groove 10 of the track column 5, and the two ends of the box-shaped lining 6 at the left and right ends of the mobile frame 1 are slidably connected to the track groove 10. The box-shaped lining 6 at the left and right ends of the mobile frame 1 can move up and down in the track groove 10 through the roller box 2.

[0021] The front end of the mobile frame 1 has a drug inlet hole 4 on the casing 6. The drug inlet hole 4 is designed as an inlet and outlet channel for the sprayer rod and nozzle. The inlet hole 4 is circular, mainly to facilitate the entry and exit of the spray rod. The diameter of the drug inlet hole 4 is approximately 5 cm. The inner side of the drug inlet hole 4 is designed with an extended plastic sleeve (soft) to prevent the chemical agent from drifting out of the hole during spraying.

[0022] The roller box 2 is fixed to the top crossbars at the left and right ends of the movable frame 1 by bolt assembly, and the central axis of the box body is parallel to the direction of the crossbars at the left and right ends of the movable frame 1 and perpendicular to the length direction of the track column 5. This ensures that the rotation direction of the roller inside the roller box 2 is completely consistent with the lifting direction of the box body 6, and avoids deviation or jamming when the lining is lifted or lowered.

[0023] Both ends of the roller are rotatably connected to the left and right side walls of the roller box 2 via ball bearings, ensuring that the roller can rotate smoothly around its own axis; a rectangular slot with a width of 5mm is provided on the surface of the roller along the length direction to fix the top edge of the box lining 6, and an anti-slip rubber pad is pasted in the slot to prevent the lining from sliding.

[0024] The roller pull line 3 is installed on the ball bearing. The roller pull line 3 is equipped with balls that match the ball bearing. When the roller pull line 3 is pulled, the balls will be locked in the gap of the ball bearing, thereby driving the ball bearing to rotate and realizing the raising and lowering of the box enclosure 6.

[0025] A spring top ball is installed on the inner side wall of the roller box 2 at the position corresponding to the toothed ball bearing. The top of the spring top ball is embedded in the tooth groove of the outer ring of the bearing. When the roller pull line 3 is stopped, the spring top ball is locked in the tooth groove under the action of elasticity, which restricts the rotation of the outer ring of the bearing, thereby realizing the positioning of the roller and preventing the drape from falling down by its own weight or wind.

[0026] The top, front, rear, left, and right sides of the housing lining 6 of the mobile frame 1 are all provided with guide channels 8. The guide channels 8 are semi-cylindrical with a diameter of 0.5 cm. Liquid receiving grooves 9 are designed at the bottom of the inner sides of the housing lining 6 of the top, front, rear, left, and right sides of the mobile frame 1. The liquid receiving grooves 9 are designed as rectangular recesses. The position of the liquid receiving grooves 9 corresponds to the bottom of the guide channels 8, and they are used to collect the liquid flowing down through the guide channels.

[0027] When in operation, the left and right end covers 6 of the mobile frame 1 are lowered, forming a sealed space with the frame. When not in operation, the left and right end covers 6 are rolled up and moved forward. The purpose of rolling them up is that the rapeseed has height, and the cover 6 needs to be raised to a certain height to pass over the rapeseed for cross-row operations. Secondly, the guide channel 8 and the liquid receiving channel 9 are designed to divert and receive the chemicals that splash onto the cover 6 after spraying, reducing pollution of the air and soil and minimizing waste.

[0028] The bottom of the movable support 1 is equipped with casters 7 for moving the entire isolation device. The casters 7 are installed at the four corners of the bottom of the movable support.

[0029] The working principle of this utility model: Raise the cloth covering the roller side of the spray box to the height of the seedlings. Move the box above the seedlings that need spraying, and lower the cloth to the same height as the side cloth to ensure sealing. The user inserts the sprayer from the spray bottle on their back into the box through the inlet to apply the pesticide. After spraying, raise the cloth covering the seedlings above the current seedlings to the height of the seedlings and move it above the next two rows of seedlings that need spraying. Plant the plants in two rows, spraying once every two rows, for a total of two rows per spray.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
