Technical Field
[0001] This utility model relates to the field of transport vehicle technology, specifically to a transport vehicle rear cover and a transport vehicle. Background Technology
[0002] Transport vehicles are large vehicles commonly used in construction and manufacturing industries for transporting materials. Most transport vehicles have a rectangular cargo box structure. After transporting materials or raw materials to the destination, the cargo box is rotated and raised to unload them into the target area. In some unloading areas, the size of the discharge opening is significantly smaller than the width or height of the transport vehicle's cargo box, making it impossible to accurately unload the materials. Therefore, robotic arms or excavators are typically used to remove the materials from the transport vehicle and transfer them to the unloading area. This transfer not only reduces the efficiency of unloading but also increases the cost of unloading, as it requires more space. Summary of the Invention
[0003] This utility model proposes a rear cover for a transport vehicle and a transport vehicle to solve the aforementioned technical problem of low unloading efficiency of transport vehicles in the prior art.
[0004] In a first aspect, this utility model provides a rear cover for a transport vehicle, including a connecting plate, a guide plate, a bottom plate, and an automatically closing cover. The connecting plate is used to dock with the edge of the transport vehicle's cargo compartment via a first connecting lock. The guide plate, the connecting plate, and the bottom plate are welded together to form a guide tongue with a gradually narrowing width. The outlet of the guide tongue is connected to the cover. A compression spring is provided inside the first connecting lock.
[0005] Optionally, the connecting plate is provided with a first bracket, and the edges of the carriage are each provided with a second bracket. The first connecting lock is used to control the distance between the first bracket and the second bracket.
[0006] Optionally, the second bracket includes a positioning groove, and the first connecting lock further includes a locking rod, the locking rod including a locking section and a holding section, the first end of the locking section being used to hinge with the first bracket, the second end of the locking section being used to abut through the positioning groove on the second bracket, and the compression spring being sleeved on the locking section.
[0007] Optionally, the cap includes a hanging ear on the upper edge and a locking hook on the lower edge. The hanging ear is used to hook onto the sleeve on the guide plate, and the locking hook is fixed to the outer surface of the base plate and is used to attach the cap close to the end face of the base plate.
[0008] Optionally, it also includes a chain, one end of which is connected to the locking hook, and the other end of which is used to connect to the frame of the transport vehicle.
[0009] Optionally, it also includes an upper cover plate, which is disposed at the upper opening of the guide tongue.

[0011] Optionally, a dustproof cloth may also be included, which can be retracted to cover the top surface of the carriage.
[0012] The principle and beneficial effects of this utility model are as follows:
[0013] Firstly, the rear cover of the transport vehicle provided by this utility model extends the discharge port of the vehicle after it is connected to the cargo box. The tapered structure formed by the guide plate makes the discharge port smaller, allowing the cargo box to directly dock with a smaller unloading area. This means that the material in the cargo box does not need to be dug out for unloading, effectively improving the unloading speed of the transport vehicle.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0022] Transport vehicles are large vehicles commonly used in construction and manufacturing industries for transporting materials. Typical transport vehicles have rectangular cargo boxes. After transporting materials to their destination, the cargo box is rotated and raised to unload the materials into the target area. In some unloading areas, the size of the discharge port is significantly smaller than the width or height of the transport vehicle's cargo box, making it impossible to accurately unload the materials. Therefore, robotic arms or excavators are often used to remove the materials from the transport vehicle and transfer them to the unloading area. This transfer not only reduces the efficiency of unloading but also increases the cost, i.e., it increases the unloading space. In view of this, this utility model provides a rear cover and a transport vehicle to solve the problem of inconvenient unloading and low unloading efficiency of existing transport vehicles.
[0023] Firstly, referring to Figures 1 to 4 As shown, this utility model provides a rear cover for a transport vehicle, including a connecting plate 1, a guide plate 2, a bottom plate 3, and an automatically closing cover 4. The connecting plate 1 is used to connect with the edge of the transport vehicle's cargo compartment via a first connecting lock 5. The guide plate 2, the connecting plate 1, and the bottom plate 3 are welded together to form a guide tongue with a gradually narrowing width. The outlet of the guide tongue is connected to the cover 4. A compression spring 51 is provided inside the first connecting lock 5.
[0024] like Figure 1 As shown, a connecting plate 1 and a guide plate 2 are welded onto the base plate 3. The edge of the connecting plate 1 needs to align with the outlet of the carriage. In this embodiment, the connecting plate 1 and the carriage are connected together using a first connecting lock 5 for easy disassembly. The rear cover of the transport vehicle provided by this utility model extends the outlet of the carriage, and the tapered structure formed by the guide plate 2 reduces the size of the outlet, allowing the carriage to directly align with a smaller unloading area. This means that the material inside the carriage does not need to be dug out for unloading, effectively improving the unloading speed of the transport vehicle.
[0025] Specifically, the connecting plate 1 is further provided with a first bracket 11, and the edges of the carriage are each provided with a second bracket 6. The first connecting lock 5 is used to control the distance between the first bracket 11 and the second bracket 6. The second bracket 6 includes a positioning groove, and the first connecting lock 5 also includes a locking rod 52. The locking rod 52 includes a locking section 521 and a holding section 522. The first end of the locking section 521 is used to hinge with the first bracket 11, and the second end of the locking section 521 is used to pass through the positioning groove on the second bracket 6 and abut against it. The compression spring 51 is sleeved on the locking section 521.
[0026] like Figure 2 As shown, the first bracket 11 and the second bracket 6 can be welded to the connecting plate 1 and the body wall of the carriage, respectively, or snapped onto the connecting plate 1 and the carriage body. In the unconnected state, the locking rod 52 of the first connecting lock 5 is hinged to the second bracket 6, and the locking rod 52 can rotate relative to the second bracket 6. When it is necessary to connect the rear cover of this transport vehicle to the carriage, bring it close to the edge of the carriage, manually push the rear cover to align the first bracket 11 and the second bracket 6, so that the connecting plate 1 is close to the end face of the carriage, and then hold the grip section 522 to pull the locking rod 52, so that the locking section 521 passes through the positioning groove on the second bracket 6, and then rotate the locking rod 52 to the locking angle (the locking angle is the position where the aforementioned locking section 521 abuts against the positioning groove). At this locking position, the spring on the locking rod 52 is compressed, so that the distance between the first bracket 11 and the second bracket 6 is compressed to the minimum.
[0027] Additionally, the aforementioned cover 4 includes a hook 41 on the upper edge and a locking hook 42 on the lower edge. The hook 41 is used to hook onto the sleeve on the guide plate 2, and the locking hook 42 is fixed to the outer surface of the base plate 3 and is used to press the cover 4 close to the end face of the base plate 3. It also includes a chain 7, one end of which is connected to the locking hook 42, and the other end of which is used to connect to the frame of the transport vehicle.
[0028] like Figure 3 As shown, hanging ears 41 are welded to both sides of the upper end of the cover plate 4. These hanging ears 41 are for attaching the cover plate 4 to the sleeve on the guide plate 2. In addition, to ensure that the cover plate 4 and the end face of the guide plate 2 are tightly attached when the carriage is in a horizontal state, and to prevent material from leaking out from the gap between them, a hanging ear 41 is provided at the middle position of the lower end of the cover plate 4. Figure 4The locking hook 42 shown has the following functions: firstly, when the carriage is in a horizontal state, it keeps the cover 4 tightly against the end face of the guide plate 2; secondly, when the carriage is at a certain angle to the car body, i.e., when the carriage is lifted for unloading, the cover 4 disengages from the locking hook 42, allowing the cover 4 to open and the material inside the carriage to flow out from the guide tongue. The chain 7 is used when the carriage is horizontal; the taut chain 7 applies tension to the locking hook 42, causing the locking hook to firmly press the cover 4 against the end face of the guide plate 2. When the carriage is lifted, the chain 7 becomes relaxed as the locking hook 42 rotates and gradually approaches the car frame.
[0029] It should be noted that the aforementioned locking hook 42 does not require a control or mechanical structure to disengage the cover 4. Instead, when the carriage is raised to a certain height, and the front end of the locking hook 42 is flush with the horizontal plane, the cover 4 automatically releases itself from the locking hook 42, allowing the cover 4 to open and the material to leak out. In practice, the depth of the locking hook 42 can be adjusted according to the lifting angle of the carriage.
[0030] In other embodiments, the rear cover of the transport vehicle provided by this utility model may further include an upper cover plate, which is disposed at the upper opening of the guide tongue. As mentioned above, the upper surface of the carriage is flush with the upper surface of the guide tongue. In this embodiment, the upper cover plate is disposed at the upper opening of the guide tongue. This serves two purposes: firstly, it prevents impurities in the unloading area from entering the guide tongue during unloading, thus affecting the quality of the material or the normal discharge of the guide tongue; secondly, it controls the uniform discharge of the guide tongue, preventing excessive material from flowing into the guide tongue due to an excessively large lifting angle of the carriage, which could lead to poor discharge or excessive discharge.
[0031] Secondly, this utility model provides a transport vehicle, including a vehicle body and a compartment that can be lifted and connected to the vehicle body, wherein the end face of the compartment is detachably connected to the rear cover of any of the aforementioned transport vehicles.
[0032] Reference Figure 5 As shown, the transport vehicle provided in this utility model, in addition to the basic vehicle body, such as the cab, frame, wheels, and cargo box, has a rear cover at the extension of the cargo box. This extends the cargo box's discharge port, and the guide tongue design reduces the size of the discharge port, allowing the cargo box to directly connect with a smaller unloading area. This eliminates the need for digging out materials from the cargo box, effectively increasing the unloading speed of the transport vehicle. Furthermore, the rear cover also increases the transport vehicle's single-carry capacity.
[0033] In some embodiments, the aforementioned transport vehicle may further include a dustproof cloth, which is retractable to cover the top surface of the cargo compartment. As described above, the upper surface of the cargo compartment is flush with the upper surface of the material guide tongue. When the cargo compartment is full of materials, the materials are exposed to sunlight. In this embodiment, a dustproof cloth is provided to cover the materials inside the cargo compartment. The mechanism for controlling the retraction of the dustproof cloth may involve two rotating mechanisms in the width direction of the cargo compartment. The dustproof cloth is fixed to one end of each rotating mechanism, so that when the rotating mechanism rotates to a first predetermined position, the dustproof cloth is retracted, and when it rotates to a second predetermined position, the dustproof cloth is slowly pulled open and covers the top surface of the cargo compartment. This rotating mechanism can be similar to the rotating mechanism of a car windshield wiper; this embodiment does not impose specific limitations on it.
[0034] Finally, this utility model provides a rear cover for a transport vehicle, which includes a connecting plate 1, a guide plate 2, a bottom plate 3, and an automatically closing cover 4. The connecting plate 1 is used to connect with the edge of the transport vehicle's cargo compartment via a first connecting lock 5. The guide plate 2, the connecting plate 1, and the bottom plate 3 are welded together to form a guide tongue with a gradually narrowing width. The outlet of the guide tongue is connected to the cover 4. A compression spring 51 is provided inside the first connecting lock 5. In this utility model, the cargo compartment can directly connect with a smaller unloading area, meaning that the material inside the cargo compartment does not need to be dug out for unloading, effectively improving the unloading speed of the transport vehicle and increasing the single-carrying capacity of the transport vehicle, thus effectively improving the practical performance of the transport vehicle.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
