Description

Technical Field

[0001] The utility model belongs to the technical field of plant germplasm collection, and specifically refers to a plant germplasm resource collection device. Background Art

[0002] Germplasm resources are also called genetic resources. Germplasm refers to the genetic material passed from the parent to the offspring of an organism. It often exists in specific varieties, such as ancient local varieties, newly cultivated promotion varieties, important genetic materials, and wild related plants, all of which fall within the scope of germplasm resources. In many fields such as botanical research, agricultural breeding, and ecological protection, the collection of plant germplasm resources is of vital importance.

[0003] Traditional plant collection tools are often relatively simple, such as ordinary scissors combined with cloth bags or simple containers for collection. However, this method has many disadvantages: on the one hand, when collecting plant leaves and branches from high places or hard-to-reach places, collectors need to use auxiliary tools such as ladders, which is not only inconvenient to operate but also poses safety risks; on the other hand, during the collection process, the cut plant samples are easy to scatter, especially some small and light leaves, which are difficult to collect accurately, resulting in sample loss and affecting the sample integrity of subsequent research.

[0004] In addition, for some plants that grow in complex terrains, such as hillsides, wetlands and other environments, it is inconvenient for collectors to carry a large number of scattered tools, and it is difficult to quickly complete the connection between cutting and collecting actions during collection, which reduces the collection efficiency. Utility Model Content

[0005] In order to solve the above-mentioned problems, the utility model provides a plant germplasm resource collection device. Through the linkage design of the pneumatic collection mechanism and the cutting and collection mechanism, at the moment of cutting the plant leaves or branches, the collection bucket can quickly approach the cutting part and accurately receive the samples. At the same time, a negative pressure state is formed in the collection box, and the samples in the collection bucket are adsorbed into the collection box for storage, while preventing the collected samples from being scattered again or being contaminated again.

[0006] In order to achieve the above-mentioned functions, the technical solution adopted by the utility model is as follows: a plant germplasm resource collection device, comprising a support rod, a handle is fixedly provided at the bottom end of the support rod, a cutting and collecting mechanism is provided at the top end of the support rod, a collecting bucket is slidably sleeved near the top end of the support rod, a collecting box is fixedly installed near the bottom end of the support rod, a collecting pipe is connected through the collecting box and the collecting bucket, and a pneumatic collecting mechanism is fixedly provided on the support rod; the pneumatic collecting mechanism comprises a piston cylinder 1 and a piston cylinder 2, the piston cylinder 1 and the piston cylinder 2 are both fixedly installed on the outer wall of the support rod, the bottom end of the piston cylinder 1 is connected with an air pipe 1, the top end of the piston cylinder 1 is connected with an air pipe 2, the air pipe 1 is connected to the bottom end of the piston cylinder 2, the air pipe 2 is connected to the collection box, and the output end of the piston cylinder 2 is fixedly connected to the bottom of the collecting bucket.

[0007] As a preferred technical solution of the utility model, a slide groove is provided on the support rod along the rod body direction, a slider is slidably arranged in the slide groove, and the bottom of the slider is fixedly connected to the output end of the piston cylinder.

[0008] As a preferred technical solution of the utility model, the cutting and collecting mechanism includes a handle and a blade, a support plate is fixedly provided at the top of the support rod, an inner pull rod is movably provided in the support plate, the top end of the inner pull rod slides through the top end of the support rod and the support plate, the bottom end of the inner pull rod slides through the bottom end of the support rod, the handles are relatively arranged in two groups and the bottom ends of the two groups of handles are respectively hinged to the two side ends of the support plate, the blade is installed on the top side wall of the handle, and a connecting rod is hinged between the handle and the top end of the inner pull rod.

[0009] As a preferred technical solution of the utility model, the sliding block is fixedly connected to the inner pull rod.

[0010] As a preferred technical solution of the utility model, a filter is installed at the port where the air pipe 2 is connected to the collection box to prevent the collected leaves or branches from being sucked into the air pipe 2.

[0011] As a preferred technical solution of the present utility model, the length of the inner pull rod is greater than the length of the support rod.

[0012] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects:

[0013] 1. Through the linkage design of the pneumatic collection mechanism and the cutting and collecting mechanism, the collection bucket can quickly approach the cutting part at the moment of cutting the plant leaves or branches, and accurately receive the samples. When the inner pull rod is pulled to cut the plant, the piston cylinder 1 moves, and the compressed air enters the piston cylinder 2, and the piston cylinder 2 simultaneously drives the collection bucket to move upward, avoiding the scattering of samples due to obstruction during falling or the influence of factors such as wind, greatly improving the collection success rate, and ensuring that precious plant germplasm resources are not wasted;

[0014] 2. The collection box is connected to the collection bucket. When the inner pull rod is pulled downward, the piston cylinder is used to absorb the air inside the collection box, forming a negative pressure state in the collection box, and the samples in the collection bucket are adsorbed into the collection box for storage. At the same time, the collected samples are prevented from being scattered again or being contaminated again. The relatively stable environment inside the collection box provides temporary storage guarantee for plant samples, maintains the original state of the samples, and is conducive to the subsequent accurate analysis and research of plant germplasm characteristics;

[0015] 3. The device has a compact structure and its components work together. There is no need to carry too many auxiliary tools, which reduces the burden on collectors and improves the flexibility and efficiency of field operations. It can be widely used in plant collection tasks under different growth environments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 and Figure 5 As shown, the cutting and collecting mechanism 3 includes a handle 31 and a blade 32. A support plate 33 is fixedly provided at the top of the support rod 1, and an inner pull rod 34 is movably provided in the support plate 33. The top end of the inner pull rod 34 slides through the top end of the support rod 1 and the support plate 33, and the bottom end of the inner pull rod 34 slides through the bottom end of the support rod 1. Two groups of handles 31 are relatively arranged and the bottom ends of the two groups of handles 31 are respectively hinged to the two side ends of the support plate 33. The blade 32 is installed on the top side wall of the handle 31. A connecting rod 35 is hinged between the handle 31 and the top of the inner pull rod 34. By pulling the bottom end of the inner pull rod 34, the inner pull rod 34 moves downward relative to the support plate 33. The inner pull rod 34 pulls the two groups of handles 31 to move toward each other through the connecting rod 35, and the blades 32 on the two groups of handles 31 realize the cutting of the target plants.

[0025] like Figure 1-Figure 4As shown, the pneumatic collecting mechanism 7 includes a piston cylinder 1 71 and a piston cylinder 2 72. The piston cylinder 1 71 and the piston cylinder 2 72 are fixedly mounted on the outer wall of the support rod 1. The bottom end of the piston cylinder 1 71 is connected with an air pipe 1 73, and the top end of the piston cylinder 1 71 is connected with an air pipe 2 74. The air pipe 1 73 is connected to the bottom end of the piston cylinder 2 72, and the air pipe 2 74 is connected to the collecting box 5. A piston plate 1 711 is movably arranged in the piston cylinder 1 71. The piston A push-pull rod 712 is connected to the top wall of the plate 1 711, and the top of the push-pull rod 712 moves through the top wall of the piston cylinder 1 71. A piston plate 2 721 is movably arranged in the piston cylinder 2 72. A push-pull rod 2 722 is connected to the top wall of the piston plate 2 721, and the top of the push-pull rod 2 722 moves through the top wall of the piston cylinder 2 72. The top of the push-pull rod 2 722 is fixedly connected to the bottom of the collecting bucket 4. A slide groove 11 is provided on the support rod 1 along the direction of its rod body. A slider 12 is provided for sliding in the slide groove 11, and the bottom of the slider 12 is fixedly connected to the top of the push-pull rod 712, and the slider 12 is fixedly connected to the inner pull rod 34. The inner pull rod 34 pulled downward synchronously drives the slider 12 to move downward in the slide groove 11, and the slider 12 drives the output end of the piston cylinder 71 to move downward, so that the gas at the lower part of the piston cylinder 71 is compressed, and the gas enters the piston cylinder 72 through the air pipe 73. The gas in the lower part of the piston cylinder 72 increases, so that the output end of the piston cylinder 72 moves upward after being affected by the pressure difference, and synchronously drives the collecting bucket 4 to move upward, and the collecting bucket 4 is lifted to the cutting and collecting mechanism 3, so as to better receive the cut leaves or branches. At the same time, the piston cylinder 71 draws the gas in the collecting box 5 to the upper part of the piston cylinder 71 through the air pipe 74, and the negative pressure in the collecting box 5 better sucks the leaves or branches received in the collecting bucket 4 into the collecting box 5.

[0026] The port connecting the air pipe 2 74 and the collecting box 5 is installed with a filter screen to prevent the collected leaves or branches from being sucked into the air pipe 2 74 ; the length of the inner pull rod 34 is greater than the length of the support rod 1 .

[0027] When in use, the collector holds the handle 2, and when the leaves or branches of the target plant that need to be collected are found, the collector holds the handle 2 stabilizing device with one hand, and holds the bottom end of the inner pull rod 34 with the other hand, and slowly pulls the inner pull rod 34 downward, and the inner pull rod 34 moves downward relative to the support plate 33, and the two sets of knife handles 31 are pulled toward each other through the connecting rod 35, and the blades 32 at the top of the knife handles 31 gradually approach each other, so as to accurately cut the leaves or branches of the target plant;

[0028] At the same time, the inner pull rod 34 drives the slider 12 to slide downward in the slide groove 11, and the slider 12 drives the push-pull rod 1 712 to move downward, and the push-pull rod 1 712 drives the piston plate 1 711 to move downward, and the piston plate 1 711 compresses the gas at the lower part of the piston cylinder 1 71 downward, and the gas at the lower part of the piston cylinder 1 71 enters the piston cylinder 2 72 through the air pipe 1 73. The gas at the lower part of the piston cylinder 2 72 increases, and the piston plate 2 721 is continuously squeezed upward by the action of the gas pressure, and the piston plate 2 721 drives the push-pull rod 2 722 to move upward, and the push-pull rod 2 722 simultaneously drives the collecting bucket 4 to move upward, quickly approaching the cutting and collecting mechanism 3, and accurately receiving the cut leaves or branches;

[0029] When the push-pull rod 712 drives the piston plate 711 to move downward, the piston cylinder 71 draws the gas in the collection box 5 to the upper part of the piston cylinder 71 through the air pipe 74, so that a negative pressure is formed in the collection box 5. Under the action of the pressure difference, the leaves or branches received in the collection bucket 4 are smoothly sucked into the collection box 5 for storage. Due to the presence of the filter net, the samples in the collection box 5 will not be reversely sucked into the air pipe. The collector releases the inner pull rod 34, and the various components slowly return to their initial state, preparing for the next collection operation. When slowly returning to the initial state, the piston cylinder 71 will blow air into the collection box 5 through the air pipe 74. The blown air flow is gentle and slow, and will not blow out the leaves or branches collected in the collection box 5.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
