Description

Technical Field

[0001] The utility model relates to the technical field of dry ice slow-release devices, in particular to a dry ice slow-release device for a greenhouse. Background Art

[0002] Common pests and diseases in greenhouses include aphids, whiteflies, etc. Dry ice can be used to effectively kill these pests. The specific method is to put dry ice blocks in a container, then place the container in the greenhouse, and wait for the dry ice to gradually evaporate and the carbon dioxide produced will kill the pests.

[0003] The common way to place dry ice in existing greenhouses is to place dry ice blocks in a container and use the carbon dioxide generated by the self-evaporation of dry ice to kill insects. This method makes the evaporation speed of dry ice uncontrollable and the evaporation cycle is long, resulting in poor insecticidal effect in the short term. Therefore, a dry ice slow-release device for greenhouses is needed to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Reference Figure 1-5 A dry ice slow-release device for a greenhouse comprises a slow-release box group 1, wherein the slow-release box group 1 comprises a dry ice box 11, wherein a frame plate 12 is connected to the bottom end of the inner wall of the dry ice box 11, a water outlet pipe 15 is connected to the bottom end of the back side of the dry ice box 11, a support plate 14 is connected to the top end of the inner wall of the dry ice box 11, and a plate group 4 is installed on the surface of the support plate 14, wherein the plate group 4 comprises a box cover 41, wherein air diffusion holes are provided on the surface of the box cover 41, and a shield plate 42 is installed on the surface of the box cover 41 through a sliding groove.

[0025] A clamping plate 43 is inserted into the through groove on both sides of the top of the dry ice box 11 , and the clamping plate 43 is inserted into the side of the box cover 41 through the clamping groove.

[0026] The clamping plate 43 is in an L-shaped structure. The inner wall of the clamping plate 43 is symmetrically connected with a return spring 44 , and the left side of the return spring 44 is connected and fixed to the outer side of the dry ice box 11 .

[0027] A plurality of partitions 13 are equidistantly connected to the inner wall of the dry ice box 11 , and a melt water chamber is provided between the bottom of the frame plate 12 and the dry ice box 11 .

[0028] A spray pipe 2 is installed inside the melt water chamber of the dry ice box 11. The spray pipe 2 consists of a horizontal pipe end and an M-shaped pipe end. A plurality of nozzle ends are equidistantly arranged outside the M-shaped pipe end of the spray pipe 2.

[0029] Two fixing components 3 are symmetrically connected to the outside of the dry ice box 11. The fixing component 3 includes a rotating shaft 31. The rotating shaft 31 is inserted into the side of the dry ice box 11 through a rotating groove. The end of the rotating shaft 31 is connected to a box plate 32, and a slider 33 is inserted into the inside of the box plate 32 through a guide groove. A clamping plate 34 is connected to the outside of the slider 33. The slider 33 is threadedly sleeved on the surface of the rotating shaft 35, and the end of the rotating shaft 35 is rotatably installed on the inner wall of the box plate 32.

[0030] A locking bolt 36 is inserted through a threaded hole on the outside of the dry ice box 11 , and the shaft end of the locking bolt 36 abuts against the surface of the rotating shaft 31 .

[0031] When the box cover 41 is installed on the surface of the support plate 14, the card plate 43 can penetrate the dry ice box 11 and then be inserted into the card slot of the box cover 41 to ensure the stability of the box cover 41 installed on the surface of the support plate 14. When the box cover 41 is placed on the surface of the support plate 14, the rebound force of the return spring 44 can push the card plate 43, so that the card plate 43 is moved and then inserted into the card slot of the box cover 41 to ensure the convenience of the card plate 43. The dry ice can be separated by the partition 13, which is convenient for sorting the dry ice. At the same time, the melt water cavity design at the bottom end of the inner wall of the dry ice box 11 can conveniently accommodate the water flow sprayed by the spray pipe 2, and conveniently collect and discharge the water flow. The M-shaped tube end design of the spray pipe 2 can expand the surface area of ​​the spray pipe 2 when spraying, so that the water flow can be sprayed out. The rate of quick-dry ice dissolution and atomization can be controlled by the transverse end valve design of the spray pipe 2, and the amount of water sprayed by the water flow can be controlled. By rotating the swivel 35, the slider 33 can be moved on the surface of the swivel 35, and then the clamping plate 34 can be controlled to move, so that the clamping plate 34 can cooperate with the side of the dry ice box 11 for clamping, which is convenient for suspending and installing the dry ice box 11. The slider 33 can be limited by the guide groove design of the box plate 32 to avoid deviation during the movement of the slider 33. The inclination angle of the clamping plate 34 can be changed by rotating the rotating shaft 31 inside the rotating groove of the dry ice box 11. When the rotating shaft 31 is adjusted, it can be rotated and moved in the threaded hole of the dry ice box 11 through the locking bolt 36, and then the shaft end of the locking bolt 36 can be abutted against the outside of the rotating shaft 31 for locking.

[0032] Working principle: According to the attached Figure 2 With attached Figure 3As shown, by cutting dry ice into pieces and placing them on the surface of the shelf 12, the dry ice can be separated by the partition 13. At this time, the box cover 41 can be placed on the surface of the support plate 14, and the card plate 43 can be driven to move by the rebound force of the reset spring 44, so that the card plate 43 moves through the dry ice box 11 and is inserted into the side of the box cover 41 to ensure the stability of the box cover 41. By moving the shield 42, the number of air holes of the box cover 41 can be changed, so that the dry ice can be easily released.

[0033] Secondly, according to the attached Figure 4 With attached Figure 5 As shown, the staff can open the valve of the spray pipe 2 to allow water to spray out from the nozzle of the spray pipe 2, so that the water is sprayed on the surface of the dry ice, thereby accelerating the volatilization speed of the dry ice. When the dry ice box 11 is installed and placed, the rotating shaft 35 can be rotated to move the slider 33 on the surface of the rotating shaft 35. The movement of the slider 33 can drive the clamping plate 34 to cooperate with the side of the dry ice box 11 to clamp and install the dry ice box 11.
