Description

Technical Field

[0001] The utility model belongs to the technical field of soil conservation boxes, and particularly relates to a soil conservation box. Background Technique

[0002] A soil conservation box is a device used to protect and maintain soil quality. It can provide a relatively stable environment, which is conducive to the activities of microorganisms in the soil and nutrient cycling, and maintain the fertility and structure of the soil.

[0003] For example, a Chinese patent with the publication number CN219762054U discloses a soil conservation box, which includes a box body. A culture dish is arranged inside the box body. A second rotating shaft is fixedly installed at the lower end of the culture dish. A pressing plate is rotatably installed on the circumferential surface of the second rotating shaft. A tension column is fixedly installed at the lower end of the pressing plate. A rotating force block is rotatably installed at the lower end of the tension column. A rotating column is fixedly installed at the side end of the rotating force block. A first threaded rod is rotatably installed at the side end of the rotating column. Ventilation openings are respectively formed through both side ends in the width direction of the box body. At least two first rotating shafts are rotatably installed on the inner side wall of the lower section of each ventilation opening. A wind blade plate is fixedly installed at the upper end of each first rotating shaft. A rotating force column is fixedly installed at the upper end of each wind blade plate. The side ends of each rotating force column are respectively hinged to the same tension rod. By installing adjustable wind blade plates on the soil conservation box, the ventilation state inside the soil conservation box can be effectively adjusted.

[0004] The above patent has the following problems:

[0005] When the above patent is in use, there are some disadvantages. For example, when the wind blade plate is opened, the wind blade plate is likely to touch the cultivated plants in the culture dish, which easily causes the branches of the cultivated plants to bend or break, affecting the water and nutrient transportation of the cultivated plants and having a certain impact on the growth of the cultivated plants. Moreover, when the excess water drains out through the drain hole, it will fall to the bottom of the inner cavity of the box body. The device cannot collect and process the excess water, and the staff still needs to clean the bottom of the inner cavity of the box, which is rather inconvenient. In view of this, we propose a soil conservation box. Content of the Utility Model

[0006] The purpose of the utility model is to provide a soil conservation box to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a soil conservation box, including:

[0008] A box body, both sides of the box body are provided with sliding grooves, a baffle is slidably installed in the sliding grooves, a pulling plate is fixedly installed at the top of the baffle, a box door is hingedly installed at the entrance of the box body, and a glass is fixedly installed on the box door;

[0009] Two fixed components, the two fixed components are respectively located in two sliding grooves and are respectively used to fix two pull plates;

[0010] A fixed plate, the fixed plate is fixedly installed in the box body, a culture tank is opened at the top of the fixed plate, a plurality of drain holes I are opened at the bottom of the fixed plate, a disc is rotatably installed at the bottom of the fixed plate, a plurality of drain holes II are opened on the disc, a plurality of funnels are fixedly installed at the bottom of the disc, a semi-circular groove is opened at the bottom of the fixed plate, and a cylinder fixed to the disc is arranged in the semi-circular groove;

[0011] A driving component, the driving component is located in the box body and is used to drive the disc to rotate;

[0012] An installation block, the installation block is fixedly installed in the box body, and a collection box is inserted and installed at the top of the installation block and below the funnel.

[0013] In this technical solution, when in use, the staff can rotate and open the box door. Subsequently, the cultivated plants together with the soil can be placed in the culture tank, water the soil, and then close the box door. Subsequently, the staff can adjust the water in the culture tank according to the cultivated plants. Through the arranged driving component, the driving component drives the disc to rotate. Then, the funnels on the disc will rotate, and the cylinder at the top of the disc will rotate and slide in the semi-circular groove until the cylinder is blocked by the semi-circular groove and cannot continue to rotate. At this time, the disc has rotated 180° forward, and a plurality of drain holes II will be respectively aligned and communicated with a plurality of drain holes I, and a plurality of funnels will be located directly above the collection box. At this time, the water in the culture tank will flow out from the plurality of drain holes II and the plurality of drain holes I and enter the plurality of funnels. Then, the water in the plurality of funnels will flow into the collection box for collection. When the water in the culture tank reaches the standard, through the arranged driving component, the driving component drives the disc to rotate 180° in the reverse direction to stop draining;

[0014] When it is necessary to ventilate the cultivated plants in the box body, the staff pulls the pull plate downward forcefully, so that the pull plate displaces downward in the sliding groove. At this time, the fixed component will release the fixation of the pull plate. Under the action of gravity, the baffle will slide downward until the baffle can no longer slide. At this time, one of the sliding grooves will be opened. Through the above operation, the other sliding groove can be opened, so that the box body can be ventilated;

[0015] During daily use, the staff can observe the inside of the box body through the glass, so as to observe the growth condition of the cultivated plants, which is more convenient.

[0016] In the above technical solution, further, the fixed component includes:

[0017] Magnet 1, said Magnet 1 is fixedly installed at the top of the chute, and at the top of the pull plate and at the bottom of Magnet 1, Magnet 2 is fixedly installed, and Magnet 2 is magnetically connected to Magnet 1.

[0018] In this technical solution, pull the pull plate downward forcefully by hand, so that the pull plate displaces downward in the chute. Subsequently, Magnet 2 at the top of the pull plate will displace downward, causing Magnet 2 and Magnet 1 to no longer be magnetically connected. At this time, the baffle will be released from fixation;

[0019] Pull the pull plate upward by hand, so that the pull plate drives the baffle to displace upward. Subsequently, Magnet 2 on the pull plate will also displace upward until Magnet 2 and Magnet 1 are magnetically connected, causing the baffle to be fixed again.

[0020] In the above technical solution, further, the drive assembly includes:

[0021] A worm gear, said worm gear is fixedly installed at the bottom of the disc. Inside the box body and below the funnel, a support plate is fixedly installed. A worm is rotatably installed on the support plate, and the worm is located on one side of the worm gear. The worm gear meshes with the worm, and the end of the worm away from the worm gear penetrates through the box body and extends to the outside.

[0022] In this technical solution, rotate the rocker on the worm forward by hand and make it drive the worm to rotate. The worm will rotate inside the support plate. Under the action of meshing, the worm will drive the worm gear to rotate. Subsequently, the worm gear will drive the disc to rotate.

[0023] In the above technical solution, further, one end of the worm is rotatably connected to the box body, and the worm gear is coaxially connected to the disc.

[0024] In this technical solution, ensure that the worm can operate normally; ensure that the worm gear can drive the disc to rotate.

[0025] In the above technical solution, further, the funnel is communicated with the corresponding drain hole 2, the diameter of the drain hole 1 is smaller than the diameter of the drain hole 2, and the drain hole 2 is communicated with the corresponding drain hole 1.

[0026] In this technical solution, ensure that the water in the drain hole 2 can enter the corresponding funnel; ensure that the water in the drain hole 1 can completely enter the corresponding drain hole 2.

[0027] In the above technical solution, further, the cylinder is slidably connected to the semi-circular groove.

[0028] In this technical solution, ensure that the cylinder can slide in the semi-circular groove

[0029] In the above technical solution, further, the drain hole 1 is communicated with the culture tank.

[0030] In this technical solution, it is ensured that the water in the culture tank can enter into the first drain hole.

[0031] The beneficial effects of the present utility model are as follows:

[0032] 1. For this soil retention box, through the cooperation among the arranged baffle, sliding groove, pulling plate and fixing component, it is ensured that when ventilating the inside of the box, the baffle will not touch the cultivated plants inside the box during the opening process, which can avoid damaging the cultivated plants in the box and prevent affecting the growth of the cultivated plants.

[0033] 2. For this soil retention box, through the mutual cooperation among the arranged funnel, first drain hole, second drain hole, mounting block and collection box, it is ensured that the water flowing out of the culture tank can be collected, preventing the water in the culture tank from flowing to the bottom of the inner cavity of the box, and there is no need for the staff to clean the bottom of the inner cavity of the box, which is relatively convenient.
