Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting equipment, in particular to a cranberry seedling culture matrix loosening device. Background Art

[0002] Cranberry seedling cultivation is a key link in the cranberry planting process. During the cranberry seedling cultivation process, cranberry seeds will be placed in a seedling tray, and the seedling tray will be filled with a seedling matrix to provide nutrients for the cranberry seedlings. During the seedling cultivation process, the humidity and temperature of the seedling tray should be kept appropriate. When the seedlings grow to a certain stage, they can be transplanted. The seedlings together with the seedling cotton can be taken out of the seedling tray and then transplanted to a larger growth space, such as a field or potted plant.

[0003] The main component of the common matrix in the seedling tray is peat soil, which is screened extensively during the production process, has uneven particle size, large difference in coarseness and fineness, and high mud content. Therefore, when watering after sowing in the tray, the fine mud with smaller particle size in the peat soil will float on the water surface. As the number of watering increases, these fine muds accumulate on the surface after the water evaporates, gradually forming a surface compaction phenomenon. The compacted matrix will lead to reduced soil permeability and water permeability, which means that water and air cannot pass through the matrix smoothly, thereby affecting the root respiration and water absorption of cranberry seedlings. Obstructed root respiration will limit the growth of seedlings, while insufficient water absorption may cause water shortage in the seedlings, affecting their normal growth and development. In addition, since most seedling trays have a structure with several cultivation chambers, it is impossible to use existing loosening tools to quickly loosen the seedling matrix in the seedling tray. Utility Model Content

[0004] The utility model aims to provide a cranberry seedling substrate loosening device, which can effectively solve the problems in the background technology.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a cranberry seedling substrate loosening device, comprising a bottom ring 1, a sleeve 9 is fixedly installed on the top of the bottom ring 1, two pressure rods 2 are movably installed on the outside of the sleeve 9, two handles 3 are fixedly installed between the two pressure rods 2, a fixing rod 4 is movably installed on the inside of the bottom ring 1, and a plurality of loosening nails 5 are fixedly installed on the bottom of the fixing rod 4.

[0022] like Figure 3-Figure 4 As shown, a mounting groove 6 is provided at the bottom of the bottom ring 1, and a plurality of rollers 7 are rotatably installed in the mounting groove 6. The outer surfaces of the rollers 7 are recessed from both sides to the center position. The bottom ring 1 is pressed against the top edge of the seedling tray 18 through the plurality of rollers 7, and the bottom ring 1 can be driven to rotate by two pressure rods 2. A fixing seat 8 is fixedly installed on the inner side of the bottom ring 1, and a screw groove is provided in the fixing seat 8, that is, one end of the fixing rod 4 is threadedly connected in the fixing seat 8. By installing one end of the fixing rod 4 in the fixing seat 8, a plurality of loosening nails 5 can be used to loosen the matrix soil in the seedling tray 18. A limiting groove 11 is provided at the top of the bottom ring 1 located at the outer side of the sleeve 9, and two guide grooves 10 are provided on the outer side of the sleeve 9.

[0023] like Figure 2-Figure 4As shown, the pressure rod 2 is a semicircular structure, with fixed plates 12 fixedly installed on both sides of the pressure rod 2, a limit ring 13 fixedly installed on the bottom of the pressure rod 2, a guide shaft 16 fixedly installed on the inner side of the pressure rod 2, and connecting blocks 14 fixedly installed on one side of the two handles 3. A slot 15 is provided on one side of the connecting block 14. The connecting block 14 is inserted and installed on the two fixing plates 12 on the adjacent sides of the two pressure rods 2 through the slot 15 and fixed by screws, that is, the two pressure rods 2 are fixedly connected by two connecting blocks 14 and inserted and installed on the outside of the sleeve 9. One side of the guide shaft 16 is inserted and installed in the corresponding guide groove 10. Through the arrangement of two handles 3 and two pressure rods 2, the pressure rod 2 can move up and down on the outside of the sleeve 9, so that the guide drive of the guide shaft 16 and the guide groove 10 can make the bottom ring 1 rotate on the seedling tray 18. The sleeve 9 between the limit groove 11 and the two pressure rods 2 is equipped with a compression spring 17. With the help of the force of the compression spring 17, the two pressure rods 2 can be pressed down and no force is applied to the pressure rods 2, so that the pressure rods 2 can perform a reset movement.

[0024] It should be noted that the utility model is a cranberry seedling substrate loosening device. When loosening the substrate in the seedling tray 18, one of the handles 3 can be held by both hands, and then the sleeve 9 and the bottom ring 1 are inserted and installed on the outside of the cranberry seedlings in the seedling tray 18 through the handles 3 and the two pressure rods 2, and the multiple rollers 7 at the bottom of the bottom ring 1 are in contact with the corresponding edges of the top of the seedling tray 18. Then, the two pressure rods 2 can be pressed downward by both hands through the two handles 3, so that the two pressure rods 2 move downward on the outside of the sleeve 9. At the same time, because the two pressure rods 2 are pressed down by both hands and the axial movement of the two pressure rods 2 is restricted, the two guide shafts are used to move the two pressure rods 2 downward. 16 is pressed down on one side in the corresponding guide groove 10 respectively, so that the bottom ring 1 rotates on the corresponding edge of the top of the seedling tray 18 with the help of the multiple rollers 7 at the bottom. At the same time, the two pressure rods 2 compress the compression spring 17 into the limit groove 11 when the outer side of the sleeve 9 moves downward. At the same time, when the bottom ring 1 rotates on the corresponding edge of the top of the seedling tray 18, the bottom ring 1 also drives the inner fixed rod 4 to rotate, so that the fixed rod 4 drives the multiple loosening nails 5 at the bottom to make circumferential motion along the outer position of the cranberry seedlings, and then the purpose of quickly loosening the matrix in the seedling bin in the seedling tray 18 can be achieved by pressing the two pressure rods 2 once, thereby improving the loosening efficiency of the seedling matrix.
