Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouse pest control, and in particular relates to a convenient hanging device for yellow belts in a greenhouse. Background Art

[0002] Greenhouse, also known as hot house, refers to a room with cold-proof, heating and light-transmitting facilities for cultivating thermophilic plants in winter. In seasons not suitable for plant growth, it is mostly used for the cultivation or seedling raising of thermophilic vegetables, flowers, trees and other plants in low temperature seasons. Crops cultivated in greenhouses will be damaged by pests, and common pests include whiteflies, whiteflies, winged aphids, American leafminers, tomato leafminers and the like. In the prior art, hanging yellow tape is usually used to lure and kill pests. Since pests have a clear tendency to yellow objects, after hanging the yellow tape, greenhouse whiteflies, winged aphids and other insects with yellow tendency will be lured by the yellow tape and fly to the yellow tape. The sticky insect glue applied on the yellow tape in advance will stick to these insects, thereby achieving the effect of killing insects.

[0003] Since the yellow tape needs to be arranged over a large area, the current method is to insert supporting wooden sticks into the ground and stick the yellow tape around the wooden sticks. However, the problem with this method is that the wooden sticks are not stable enough when inserted into the soil and will become loose over time. When the wooden sticks fall, the yellow tape will fall into the soil and lose its insect control effect. In addition, since the yellow tape needs to be arranged over a long period of time, it occupies a large area and is set around the crops, it will take up more space in the greenhouse and hinder the movement of staff in the greenhouse, bringing inconvenience to normal work and activities. Utility Model Content

[0004] In order to solve the problems in the prior art, the utility model provides a convenient hanging device for yellow belts in a greenhouse, which has adjustability and extensibility. By hanging the yellow belts, it can not only ensure the quality of insect removal, but also avoid hindrance and influence on ground activities.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 The utility model discloses a convenient hanging device for yellow belt 4 in a greenhouse, comprising a supporting top frame 1, wherein the supporting top frame 1 is fixedly arranged on the top of the greenhouse. According to actual needs, the supporting top frame 1 is set to different sizes. In a specific implementation, the supporting top frame 1 should be set to a sufficiently large range to cover all crops in the greenhouse, or multiple groups of supporting top frames 1 are set to arrange yellow belts 4 at different positions to catch pests.

[0020] A connecting hole 2 is provided at the bottom of the supporting top frame 1, and an extending support rod 3 is detachably connected to the supporting top frame 1. A plurality of connecting holes 2 are densely distributed to facilitate installation of the extending support rod 3 at different positions. A yellow belt 4 is provided on the extending support rod 3.

[0021] Among them, in order to increase the range that can be used to place the yellow belt 4, the bottom of the extended support rod 3 can be detachably connected to another extended support rod 3, and the extended support rods 3 can be connected to each other, thereby increasing the downward range of the extended support rod 3, so that the position where the yellow belt 4 can be wrapped is lower and the range is larger.

[0022] Embodiment 1

[0023] like Figure 4 A threaded joint 5 is provided at the top of the extended support rod 3, a threaded slot 6 is provided at the bottom of the extended support rod 3, the connecting hole 2 at the bottom of the supporting top frame 1 is a threaded hole, the extended support rod 3 and the supporting top frame 1 are threadedly connected, and another extended support rod 3 can be connected to the bottom of the extended support rod 3. The number of connected extended support rods 3 is set according to specific needs, so that the crops can be completely covered after the yellow belt 4 is arranged.

[0024] When in use, the extension support rod 3 is rotated and connected to the connection hole 2 at the bottom of the support top frame 1, and then the extension support rod 3 is rotated and connected again at the bottom of the extension support rod 3 through a threaded connection, thereby realizing the installation of multiple extension support rods 3 and multiple layers of extension support rods 3. When it is necessary to disassemble, it is only necessary to rotate the extension support rod 3.

[0025] Embodiment 2

[0026] like Figure 5 A connecting plug 7 is provided at the top of the extended support rod 3, a connecting slot 8 is provided at the bottom of the extended support rod 3, and a connecting slot 8 is also provided in the connecting hole 2 at the bottom of the supporting top frame 1. A limiting assembly 9 is provided in the connecting plug 7, and the limiting assembly 9 includes a limiting head 10, a connecting shaft 11, a limiting arm 12 and a limiting arm 2 13. The connecting shaft 11 is arranged in the extended support rod 3, the limiting arm 12 and the limiting arm 2 13 are cross-arranged, and the middle ends of the limiting arm 12 and the limiting arm 2 13 are hinged on the connecting shaft 11, the limiting head 10 is arranged on the limiting arm 12 and the limiting arm 2 13, a telescopic hole 14 is provided on the extended support rod 3, and the limiting head 10 extends out of the telescopic hole 14, and a control hole 15 is provided on the extended support rod 3. The bottoms of the limiting arm 12 and the limiting arm 2 13 extend out of the control hole 15, and the bottoms of the limiting arm 12 and the limiting arm 2 13 are provided with a pressing piece 17.

[0027] A limiting hole groove 16 is provided in the connection slot 8 , and the limiting hole groove 16 corresponds to the limiting head 10 .

[0029] Insert the connecting plug 7 at the top of the extension support rod 3 into the connecting slot 8 at the bottom of the extension support rod 3. After insertion, the limit head 10 is squeezed and compressed into the extension support rod 3. When the limit head 10 moves to the limit hole groove 16 in the connecting slot 8, the elastic force of the torsion spring pushes the limit arm 12 and the limit arm 2 13 to rotate, so that the limit head 10 is pushed into the limit hole groove 16, thereby realizing the extension support rod 3 and the connection top frame, and then the extension support rod 3 can be connected again at the bottom of the extension support rod 3.

[0030] When disassembly is required, the pressing piece 17 on the top of the extended support rod 3 is pressed to drive the limiting arm 12 and the limiting arm 2 13 to rotate, so that the limiting head 10 is moved out of the limiting hole 16, and the extended support rod 3 can be pulled off.

[0031] During specific use, the position of the extended support rod 3 is set according to the planting layout of the crops, and the extension length of the extended support rod 3 is set according to the height of the crops, so that the extended support rod 3 can completely cover the crops without hindering other work activities.

[0032] Specifically, first, the extended support rod 3 is installed in the connecting hole 2 at the bottom of the supporting top frame 1 to form a first layer of extended support rods 3, and then an extended support frame is continued at the bottom of the first layer of extended support rods 3 to form a second layer of extended support frame. According to actual needs, multiple layers of extended support frames can be continued to form, and then the yellow belt 4 can be wrapped thereon so that the yellow belt 4 covers the crops and improves the insecticidal effect.
