[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a grain truck unloading and recycling device, including a truck bed 1 for loading grain, with wheels on the lower side. A conveyor 2 is provided on the front side of the truck bed 1 for unloading grain from the truck bed 1 and transporting it to a designated location to improve unloading efficiency. This technology is prior art, so it will not be described in detail. Two sets of locking blocks 3 are fixedly connected to the upper front side of the truck bed 1 to limit the limiting rod 45, thereby stretching and fixing the waterproof canvas 42. An installation shell 4 is fixedly connected to the upper rear side of the truck bed 1. The shell is hollow inside and serves as the installation carrier for the waterproof components, providing installation space and protection for the geared motor 41, the rotating shaft, and the waterproof canvas 42. A waterproof component is provided on the inner wall of the installation shell 4. The waterproof component includes a geared motor 41, which provides power for the rotation of the rotating shaft. By controlling the forward and reverse rotation of the geared motor 41, the retraction and unfolding operation of the waterproof canvas 42 can be realized. The geared motor 41 is fixedly connected to the inner wall of the installation shell 4.
[0032] Furthermore, the output shaft of the geared motor 41 is fixedly connected to a rotating shaft. The rotating shaft drives the waterproof canvas 42 to be extended and retracted. The rotating shaft is rotatably connected to the inner wall of the mounting shell 4. The waterproof canvas 42 is wrapped around the outside of the rotating shaft. In the unfolded state, it can cover the top of the truck bed 1, providing waterproof, sun protection, and dust protection, protecting the grain from external environmental factors. A limit rod 45 is fixedly connected to the front of the waterproof canvas 42, which cooperates with the locking block 3 to limit the waterproof canvas 42. Fixing holes 43 are evenly arranged on the left and right sides of the waterproof canvas 42, which cooperate with the limit post 46 to ensure the stability of the waterproof canvas 42 in the unfolded state.
[0033] Reference Figure 2 and Figure 4 A stabilizing roller 44 is rotatably connected to the inner wall of the mounting shell 4, which guides and supports the waterproof canvas 42, making the waterproof canvas 42 more stable during the unfolding and retraction process. The outer side of the stabilizing roller 44 is made of rubber, which can increase the friction between it and the waterproof canvas 42 and reduce the wear on the waterproof canvas 42. The lower part of the waterproof canvas 42 slides on the outer side of the stabilizing roller 44. A limiting post 46 is slidably connected to the inner wall of the truck bed 1, which can be inserted into the inner wall of the fixing hole 43 to fix both sides of the waterproof canvas 42. The right side of the limiting post 46 is elastically connected to the truck bed 1 through a return spring 47, which provides elastic restoring force to the limiting post 46. When it is necessary to retract the waterproof canvas 42, the return spring 47 can help the limiting post 46 disengage from the fixing hole 43.
[0034] Reference Figure 2 and Figure 3 A cleaning assembly is provided on the front side of the mounting shell 4. The cleaning assembly includes an insert plate 51, which is inserted into the upper inner wall of the front side of the mounting shell 4. It provides a mounting base for the slide rod 54, compression spring 55, moving plate 56, fixed plate 52 and scraper 53. At the same time, the insert plate 51 is limited by bolts to prevent it from loosening. The lower inner wall of the insert plate 51 is slidably connected to the slide rod 54, and multiple sets are provided. The up and down movement of the slide rod 54 can drive the moving plate 56 and scraper 53 to move up and down. The upper part of the slide rod 54 is elastically connected to the insert plate 51 through the compression spring 55, which provides elastic restoring force to the slide rod 54, so that the scraper 53 can fit tightly against the outside of the waterproof canvas 42.
[0035] Furthermore, a movable plate 56 is fixedly connected to the bottom end of the slide bar 54, which moves with the slide bar 54 to provide an installation position for the scraper 53 and ensure the stability of the scraper 53 when cleaning the waterproof canvas 42. Fixed plates 52 are fixedly installed on the bottom ends of the left and right sides of the insert plate 51 by bolts. The fixed plates 52 are U-shaped to provide an installation position and support for the scraper 53 and ensure the stability of the scraper 53 when cleaning the waterproof canvas 42. The scraper 53 is fixedly connected to the upper part of the fixed plate 52.
[0036] Furthermore, multiple sets of scrapers 53 are provided, and these sets of scrapers 53 are respectively located at the bottom of the movable plate 56. The opposite sides of the multiple sets of scrapers 53 slide on the outer side of the waterproof canvas 42 to clean water stains on the waterproof canvas 42, keep the waterproof canvas 42 clean, and improve the service life of the waterproof canvas 42. The front side of the scraper 53 is inclined to facilitate the removal of water stains from the surface of the waterproof canvas 42 during the cleaning process, thereby improving the cleaning effect.
[0037] Working principle: When in use, if it is rainy and the grain in the truck bed 1 needs to be protected, start the reduction motor 41 in the mounting shell 4. The output shaft of the reduction motor 41 drives the rotating shaft to rotate, and the waterproof canvas 42 wrapped around the outside of the rotating shaft gradually unfolds, pulling the limit rod 45.
[0038] When the limiting rod 45 moves to the locking block 3 at the upper front of the truck bed 1, the limiting rod 45 is limited by the locking block 3. At this time, the reverse rotation of the reduction motor 41 straightens the waterproof canvas 42, thereby stretching and fixing the waterproof canvas 42. Simultaneously, the waterproof canvas 42 is bent, the limiting post 46 is pressed, and the return spring 47 is squeezed. The fixing hole 43 is aligned with the limiting post 46. Then, through the elastic force of the return spring 47, the limiting post 46 is driven to insert into the inner wall of the fixing hole 43, limiting the waterproof canvas 42 and ensuring the stability of the waterproof canvas 42 in the unfolded state, thus playing a role in waterproofing and dustproof protection.
[0039] When the waterproof canvas 42 needs to be stored, the fixing hole 43 is removed from the outside of the limiting post 46, and then the reduction motor 41 rotates in the opposite direction to store the waterproof canvas 42. Under the elastic action of the compression spring 55, the slide rod 54 drives the moving plate 56 and the multiple sets of scrapers 53 set on the moving plate 56 and the fixing plate 52 to fit tightly against the outside of the waterproof canvas 42, scraping off the water stains on the surface of the waterproof canvas 42, keeping the waterproof canvas 42 clean and improving its service life.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
