[0034] Furthermore, first, the motor 18 is started, and the output shaft of the motor 18 drives the gear 19 and the gear 2 10 to rotate simultaneously. The gear 19 drives the rack plate 15 to slide along the top of the fixed block 6 through meshing, and then the rack plate 15 drives the slide cover 2 to move to the left. At the same time, the gear 2 10 drives the gear 3 11 to rotate through meshing, and then the gear 3 11 drives the slide cover 2 3 to move to the right along the movable groove 20 through the rack plate 27, so that the slide cover 1 2 and the slide cover 2 3 move simultaneously, so that the top of the car body is automatically opened and closed. The opening and closing of the top can provide a better field of view and accessibility, ensure the safety and integrity of the goods, and reduce the risk of theft and damage.
[0035] Reference Figure 3 , Figure 6 and Figure 7 The moving component includes a motor 2 13, the outside of the motor 2 13 is fixedly connected to the outside of the support plate 12, and the bottoms of the two support plates 12 are provided with limiting grooves 14, the inner wall of one of the limiting grooves 14 is rotatably connected with a threaded rod 15, the outer surface of the threaded rod 15 is threadedly connected with a pressure block 22, the outer surface of the pressure block 22 is provided with a moving groove 18, the inner side wall of the moving groove 18 is provided with a plurality of card grooves 23, the inner wall of the moving groove 18 is slidably connected with a connecting rod 16, the interior of the connecting rod 16 is provided with two internal grooves 17, the inner wall of the internal groove 17 is slidably connected with a baffle 26, one side of the baffle 26 is fixedly connected with a card block 25, the other side of the baffle 26 is fixedly connected with a pull rod 24, and the outer sleeve of the pull rod 24 is provided with a spring 27.
[0036] Furthermore, when the compartment 1 is loaded with materials, the materials are unevenly distributed inside the compartment 1. First, the two pull rods 24 are pulled outward at the same time. The pull rods 24 drive the baffle 26 to slide along the inner wall of the internal groove 17, and then drive the block 25 to move at the same time until the block 25 is completely retracted into the interior of the internal groove 17. At this time, the spring 27 is in a compressed state, and then the connecting rod 16 is moved to a specified position, and then the pull rod 24 is released. Under the elastic force of the spring 27, the block 25 is stuck in other slots 23 to complete the adjustment of the height of the connecting rod 16, and then the motor 2 13 is started. The output end of the motor 2 13 drives the threaded rod 15 to rotate, and then drives the connecting rod 16 to slide through the pressure block 22, so as to flatten the materials inside the compartment 1. The evenly distributed materials are conducive to air circulation, reduce the possibility of moisture, mildew and insect pests on the materials, and maintain the quality and freshness of the materials.
[0037] Reference Figure 2 and Figure 4 The transmission shaft of motor 18 is fixedly connected to gear 2 10 on the outside, and the outer side of gear 2 10 is meshedly connected with the outer side of gear 3 11 at the corresponding position; the outer side of gear 19 is meshedly connected with the outer side of rack plate 1 5 at the corresponding position, and the outer side of gear 3 11 is meshedly connected with the outer side of rack plate 2 7 at the corresponding position.
[0038] Furthermore, the motor 18 drives the gear 2 10 to rotate, and under the meshing action of the gear 2 10, the gear 3 11 rotates at the same time, and the gear 3 11 drives the rack plate 2 7 to move along the top of the support plate 12. At this time, the gear 19 drives the rack plate 1 5 to move along the top of the fixed block 6 through meshing, so that the rack plate 1 5 and the rack plate 2 7 are more stable, further improving their stability and reliability.
[0039] Reference Figure 2 , Figure 4 and Figure 5The outer side of rack plate 1 5 is fixedly connected to the inner side of slide cover 1 2 , and the outer side of rack plate 2 7 is fixedly connected to the inner side of slide cover 2 3 ; the inner wall of movable groove 20 is rotatably connected with a plurality of pulleys, and the outer side of the pulleys is slidably connected to the groove of I-shaped block 21 .
[0040] Furthermore, the rack plate 15 drives the sliding cover 12 to slide to the left along the inner wall of the movable groove 20, and then the rack plate 27 drives the sliding cover 23 to slide to the right, thereby improving the opening and closing efficiency of the carriage; when the sliding cover 12 and the sliding cover 23 move, the pulley slides along the groove of the I-shaped block 21, effectively reducing the wear of the sliding cover 12 and the sliding cover 23 and extending the service life of the equipment.
[0041] Reference Figure 3 and Figure 7 The inner wall of another limiting groove 14 is fixedly connected with a slide rod 19, and the outer side of the slide rod 19 is slidably connected with another pressure block 22; one end of the spring 27 is fixedly connected to the outer side of the baffle 26, and the other end of the spring 27 is fixedly connected to the inner wall of the internal groove 17.
[0042] Furthermore, the stability of the connecting rod 16 can be increased by the sliding rod 19, making the connecting rod 16 more stable when moving, thereby improving the efficiency of the connecting rod 16 in dispersing the material in the chamber 1; the baffle 26 is limited by the spring 27 to prevent the baffle 26 from sliding freely along the inner wall of the internal groove 17 and affecting the stability of the block 25.
[0043] Working principle: first start the motor 8, the output shaft of the motor 8 drives the gear 19 and the gear 2 10 to rotate simultaneously, the gear 19 drives the slide cover 2 to move to the left through the rack plate 15, the gear 2 10 drives the gear 3 11 to rotate through the meshing, and then the gear 3 11 drives the slide cover 2 3 to move to the right through the rack plate 27, so that the top of the car body opens and closes automatically. The opening and closing of the top of the car body can make fuller use of the upper space of the car body, optimize the storage and loading methods of goods, and enhance the practicality of the car body.
[0044] In addition, when the compartment 1 is loaded with materials, the materials are unevenly distributed inside the compartment 1. First, the two pull rods 24 are pulled outward at the same time. The pull rods 24 drive the block 25 to disengage the slot 23 through the baffle 26, and then move the connecting rod 16 upward or downward, and then release the pull rod 24. Under the elastic force of the spring 27, the block 25 is inserted into other slots 23 to complete the adjustment of the height of the connecting rod 16, and then start the motor 2 13. The output end of the motor 2 13 drives the threaded rod 15 to rotate. Under the action of the thread of the threaded rod 15, the connecting rod 16 slides to flatten the material inside the compartment 1, making the material distribution more even, avoiding the material extrusion or agglomeration caused by uneven stacking, and ensuring the full utilization of the storage space.
