Description

Technical Field

[0001] The utility model relates to a sampling device for diseases and pests of larch, in particular to a sampling device for diseases and pests of larch, belonging to the technical field of sampling devices for forestry diseases and pests. Background Technique

[0002] In recent years, due to the overdevelopment of forestry resources and the increasingly deteriorating ecological environment, diseases and pests of larch show a trend of high incidence and frequent occurrence, and have become the main diseases and pests of forestry in China. However, in real life, we can know that there are many types of pests and diseases that can damage larch. In order to treat pests and diseases targeted, people usually need to use sampling devices to sample the types of pests and diseases.

[0003] When using a sampling device for sampling, people usually fix the sticky board around the outside of the branches of larch. When different types of pests and diseases damage larch, once they fall on the sticky board, they will be stuck by the glue layer on the sticky board, so as to realize the sampling of pests and diseases. However, in real life, we can know that due to the different diameters of the branches of larch in different years, the required lengths of the sticky boards are also different. However, in the existing technology, the sticky board usually does not have a length adjustment function. In this way, not only the applicable range of the sticky board for larch in different years is limited, but also the practicability of the sampling device is reduced. At the same time, because the glue layer is coated on the sticky board, when people fold and carry the sticky board, the glue layers will stick to each other, resulting in more laborious opening and even damage to the sticky board. Content of the Utility Model

[0005] The utility model provides a sampling device for diseases and pests of larch to solve the problems that the sticky board in the existing technology usually does not have a length adjustment function, resulting in limited applicable range for larch in different years and more laborious opening of the sticky board by people.

[0024] The embodiments of the present utility model provide a larch pest sampling device.

[0025] Please refer with emphasis to Figure 1 , Figure 2 , Figure 3 and Figure 4, including a pest sampling sticky board 1. The outer surface of the pest sampling sticky board 1 is coated with an adhesive layer. When pests attach to the pest sampling sticky board 1, they will be stuck by the adhesive layer. An adjusting mechanism 2 is arranged on the outer surface of the pest sampling sticky board 1. By setting the adjusting mechanism 2, the length of the pest sampling sticky board 1 can be adjusted, so that it is suitable for larch in different years. The adjusting mechanism 2 includes an adjusting box 201 and an adjusting belt 202. A group of positioning holes 203 are arranged on the outer surface of the adjusting belt 202. A reserved cavity 204 is arranged on the outer surface of the adjusting box 201. Symmetrically arranged fixing seats 205 are fixedly connected to the outer surface of the adjusting box 201. The inner walls of the two fixing seats 205 are both hinged with connecting cylinders 206, and the connecting cylinders 206 can be turned over on the inner walls of the fixing seats 205;

[0026] Both inner walls of the two connecting cylinders 206 are slidably connected with connecting rods 207. Symmetrically arranged T-shaped platforms 208 are fixedly connected to the outer surfaces of the two connecting rods 207. The T-shaped platforms 208 extend to the outside of the connecting cylinders 206 and are slidably connected with the connecting cylinders 206. The T-shaped platforms 208 can limit the connecting rods 207 to prevent them from detaching from the connecting cylinders 206. Springs 209 are fixedly connected to the outer surfaces of the two connecting rods 207, and the springs 209 are fixedly connected to the inner walls of the connecting cylinders 206. Positioning rods 210 are fixedly connected to the outer surfaces of the two connecting rods 207.

[0027] Please refer specifically to Figure 2 , the adjusting box 201 is fixedly connected to the outer surface of the pest sampling sticky board 1, and the adjusting belt 202 is fixedly connected to the outer surface of the pest sampling sticky board 1.

[0028] Please refer specifically to Figure 2 , the adjusting belt 202 is adapted to the reserved cavity 204, and the positioning rods 210 are adapted to the positioning holes 203. By changing the length of the adjusting belt 202 inserted into the reserved cavity 204, the length of the pest sampling sticky board 1 can be adjusted. By inserting the positioning rods 210 into the positioning holes 203 at different positions, positioning of different lengths of the adjusting belt 202 inserted into the reserved cavity 204 can be achieved.

[0029] Please refer specifically to Figure 4 , the positioning rods 210 extend into the adjusting box 201 and are slidably connected with the adjusting box 201. Symmetrically arranged reserved grooves are arranged on the outer surface of the connecting cylinder 206, and the T-shaped platforms 208 are slidably connected with the connecting cylinder 206 through the reserved grooves arranged on the outer surface of the connecting cylinder 206.

[0030] Please refer specifically to Figure 3 , a group of fixing strips 3 are fixedly connected to the outer surface of the pest sampling sticky board 1. A protective pad 4 is fixedly connected to the outer surface of each fixing strip 3. The fixing strips 3 have a certain thickness, so as to prevent the adhesive layers on the surface from sticking together after the pest sampling sticky board 1 is folded.

[0031] When the utility model is in use: First, put the pest sampling sticky board 1 on the outside of the branches of the larch. Then, insert the adjusting belt 202 into the adjusting box 201 through the reserved cavity 204 until the inner surface of the pest sampling sticky board 1 is attached to the branches of the larch. At this time, by pulling the connecting rod 207 until the positioning rod 210 can be inserted into the inside of the adjusting box 201 and inserting the positioning rod 210 into the positioning hole 203, by inserting the positioning rod 210 into the positioning holes 203 at different positions, the positioning of different lengths of the adjusting belt 202 inserted into the reserved cavity 204 can be realized, so that people can adjust the length of the pest sampling sticky board 1 according to the larch of different years. This not only expands the applicable range of the pest sampling sticky board 1 for larch of different years, but also improves the practicability of the device. At the same time, during the folding and carrying process of the device, with the folding of the pest sampling sticky board 1, under the action of the self-thickness of the fixing strip 3, it can prevent the adhesive layers on the outer surface of the pest sampling sticky board 1 from coming into contact, so that the adhesive layers will not stick to each other, thus avoiding the situation that the pest sampling sticky board 1 is damaged when people open the pest sampling sticky board 1 due to the mutual adhesion of the adhesive layers.
