Description

Technical Field

[0001] The invention relates to the technical field of environmental protection machinery, and in particular to a self-loading and unloading garbage truck. Background Art

[0002] With the progress of society and the rapid development of economy, the development process of urban and rural areas is accelerating, and people's income and consumption level are gradually increasing, but at the same time, the amount of urban garbage is increasing day by day. Self-loading and unloading garbage trucks (referred to as self-loading and unloading trucks) occupy an important position in garbage disposal and transfer equipment. At present, 240L and 120L garbage cans are mainly used for garbage disposal in cities and villages. Self-loading and unloading garbage trucks use special mechanisms to collect and transfer garbage in garbage cans to large mobile stations or fixed stations for compression treatment.

[0003] There are two main opening modes for the rear doors of self-loading garbage trucks on the market. The rear doors of small vehicles (volume ≤ 7 cubic meters) are manually locked by a handle. When the garbage is unloaded, the unloading angle and its own gravity are used to open it, and the opening angle and position cannot be controlled. Due to the limited size of the hoppers of mobile stations and fixed stations, the opening of the rear doors of self-loading and unloading vehicles is limited or interferes with the hopper, resulting in the inability to use them together. Large self-loading and unloading vehicles (volume ≥ 8 cubic meters) have a push shovel mechanism inside, and the rear door is hydraulically opened and locked. When the garbage needs to be unloaded, the rear door is turned 90° by the cylinder, and the push shovel inside the box pushes the garbage out to complete the garbage unloading. Due to the limited volume of the mobile station hopper, large self-loading and unloading vehicles need to be docked with fixed stations. When the garbage is unloaded, the full opening of the rear door will interfere with the fixed station hopper. If it is not fully opened, the push shovel will not only be inefficient when pushing the garbage to unload, but it may also cause damage to the rear door. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a self-loading and unloading garbage truck with a slide rail type rear door opening mechanism which is convenient and safe to operate and avoids interference between the rear door of the self-loading and unloading garbage truck and the hopper of a garbage station.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a self-loading and unloading garbage truck with a sliding rail type rear door opening mechanism, comprising a box body installed on a car chassis, a rear door installed at the rear end of the box body, a rotating limit track installed at the top of the rear end of the box body, a sliding track docking with the rotating limit track installed at the top of the box body, a rotating slider movably installed on the rotating limit track, the rotating slider is fixedly connected to the rear door, and a power device driving the rotating slider to flip and slide along the sliding track is also installed on the top of the box body.

[0006] As a preferred technical solution, the rotating limit track includes a circular sliding cavity, a horizontal limit wall is provided at the rear of the sliding cavity in the horizontal direction, a vertical limit wall is provided at the upper part of the sliding cavity in the vertical direction, and the front end of the sliding cavity is connected to the sliding track; a limiting surface corresponding to the horizontal limit wall and the vertical limit wall is provided on one side of the rotating slider, and a sliding surface corresponding to the sliding cavity is provided on the other side of the rotating slider.

[0007] As a preferred technical solution, the limiting surface is a plane, and the sliding surface is an arc surface.

[0008] As a preferred technical solution, there are two rotation limiting rails, and correspondingly there are also two sliding rails, and the power device is installed between the two sliding rails.

[0009] As a preferred technical solution, the power device is an oil cylinder, a cylinder body of the oil cylinder is hinged to the box body, and a piston shaft of the oil cylinder is hinged to the rear door.

[0010] As a preferred technical solution, one end of a hook-shaped locking plate is fixedly mounted on the rotating slider, and the other end of the locking plate is hinged to the rear door.

[0011] Due to the adoption of the above technical scheme, the self-loading and unloading garbage truck with a slide rail type rear door opening mechanism comprises a box body installed on a vehicle chassis, a rear door is installed at the rear end of the box body, a rotating limit track is installed at the top of the rear end of the box body, a sliding track docking with the rotating limit track is installed at the top of the box body, a rotating slider is movably installed on the rotating limit track, the rotating slider is fixedly connected to the rear door, and a power device for driving the rotating slider to flip and slide along the sliding track is also installed on the top of the box body; the beneficial effect of the present invention is that when the rear door is opened and the garbage is self-unloaded, the power device pulls the rear door together with the rotating slider to start rotating and opening under the guidance of the rotating limit track, when the rear door rotates and opens to 90°, the rotating limit track will limit the rotating slider so that it cannot continue to rotate, at this time, the upper and lower planes of the rotating slider are exactly parallel to the sliding track, and under the continuous pulling force, the rotating slider drives the rear door to enter the sliding track and start sliding until the rear door is fully opened and has flipped to the top of the box body. After the rear door is fully opened, the shovel inside the box pushes the garbage out and pours it into the hopper, and there is no interference between the rear door and the rear end of the hopper; when the rear door is closed, as the garbage is unloaded, the vehicle leaves the hopper area, and the power device pushes the rear door to slide along the sliding track toward the rear end of the box until it enters the rotating limit track. After entering the rotating limit track, due to the limiting effect of the rotating limit track on the rotating slider, the rear door starts to rotate along the rotating limit track until the rear door is closed. The present invention adopts a structure combining sliding and rotating rails, which solves the matching problem of existing self-loading and unloading garbage stations, avoids the danger caused by the interference of the rear door, and realizes the fully automatic unloading of vehicle garbage without the need to manually adjust the position of the rear door to avoid the hopper of the garbage station; it improves the safety performance of the vehicle during operation and reduces operating costs.

[0022] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0023] like Figures 1 to 8As shown, the self-loading and unloading garbage truck with a slide rail rear door opening mechanism comprises a box body 2 installed on a vehicle chassis 1, a rear door 3 is installed at the rear end of the box body 2, a rotating limit track 6 is installed on the top of the rear end of the box body 2, a sliding track 7 docking with the rotating limit track 6 is installed on the top of the box body 2, a rotating slider 4 is movably installed on the rotating limit track 6, the rotating slider 4 is fixedly connected to the rear door 3, and a power device for driving the rotating slider 4 to flip and slide along the sliding track 7 is also installed on the top of the box body 2; the beneficial effects of the present invention are: when the rear door 3 is opened, the rear door 3 is opened, and the rear door 3 is opened. When starting and unloading garbage, the power device pulls the rear door 3 together with the rotating slider 4 to start rotating and opening under the guidance of the rotating limit track 6. When the rear door 3 rotates and opens to 90°, the rotating limit track 6 will limit the rotating slider 4 so that it cannot continue to rotate. At this time, the upper and lower planes of the rotating slider 4 are exactly parallel to the sliding track 7. Under the action of continuous pulling force, the rotating slider 4 drives the rear door 3 to enter the sliding track 7 and start sliding until the rear door 3 is fully opened and has flipped to the top of the box body 2. After the rear door 3 is fully opened, the shovel 9 inside the box 2 pushes the garbage out and pours it into the hopper 10, and there is no interference problem between the rear door 3 and the rear end of the hopper 10; when the rear door 3 is closed, as the garbage is unloaded, the vehicle leaves the hopper 10 area, and the power device pushes the rear door 3 to slide along the sliding track 7 toward the rear end of the box 2 until it enters the rotating limit track 6. After entering the rotating limit track 6, due to the limiting effect of the rotating limit track 6 on the rotating slider 4, the rear door 3 starts to rotate along the rotating limit track 6 until the rear door 3 is closed. The present invention adopts a structure combining sliding and sliding of the slide rail type, which solves the matching problem of the existing self-loading and unloading garbage station, avoids the danger caused by the interference of the rear door 3, and realizes the full automatic completion of the vehicle garbage unloading, without the need to manually adjust the position of the rear door 3 to avoid the hopper 10 of the garbage station; improves the safety performance of the vehicle during operation and reduces the operating cost.

[0024] like Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the rotation limit track 6 includes a circular sliding cavity, a horizontal limit wall is provided at the rear of the sliding cavity, a vertical limit wall is provided at the upper part of the sliding cavity, and the front end of the sliding cavity is connected to the sliding track 7; a limit surface corresponding to the horizontal limit wall and the vertical limit wall is provided on one side of the rotating slider 4, and a sliding surface corresponding to the sliding cavity is provided on the other side of the rotating slider 4. The rotating slider 4 can rotate 90° in the sliding cavity. When in the starting position, as shown in FIG. Figure 2As shown, the limiting surface of the rotating slider 4 is facing backward in the vertical direction, and the vertical limiting wall at the upper part of the sliding cavity plays a limiting role. When the rear door 3 starts to rotate, the rotating slider 4 rotates clockwise in the rotating limiting track 6. When the rear door 3 is fully opened, the limiting surface of the rotating slider 4 is facing upward in the horizontal direction, and the horizontal limiting wall at the lower part of the sliding cavity plays a limiting role, preventing the rotating slider 4 from continuing to rotate. Therefore, the rotating limiting track 6 limits the rotating slider 4 through its own structure, so that it cannot continue to rotate.

[0025] When the limiting surface is a plane and the sliding surface is an arc surface, it is a preferred technical solution, and the sliding and limiting effects of the rotating slider 4 are optimal.

[0026] There are two rotation limiting rails 6, and correspondingly there are two slide rails 7, and the power device is installed between the two slide rails 7. The two sets of slide rails enhance the sliding stability of the rear door 3.

[0027] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the power device is a cylinder 8, the cylinder body of the cylinder 8 is hinged to the box body 2, and the piston shaft of the cylinder 8 is hinged to the rear door 3. When the power device is the cylinder 8, the cylinder 8 can be connected to the hydraulic system of the automobile chassis 1. When the rear door 3 is opened, the cylinder 8 shrinks, and when the rear door 3 is closed, the piston shaft of the cylinder 8 extends. At this time, the rear door 3 is tightly fitted with the box body 2, and the cylinder 8 still has a thrust effect on the rear door 3. The cylinder 8 is integrated with a built-in hydraulic lock to ensure that the cylinder 8 is recovered without taking power, and the sealing effect between the rear door 3 and the box body 2 is better, and there will be no property leakage during the garbage transportation process. The present invention solves the problem that the rear door 3 of the existing self-loading and unloading garbage trucks interferes with the garbage station when the garbage is unloaded, improves the compatibility of the self-loading and unloading vehicles and the stations, avoids the danger caused by the interference of the rear door 3, and realizes the full automatic completion of the vehicle's garbage unloading without the need to manually adjust the position of the rear door 3 to avoid the hopper 10; the effect of sharing the oil cylinder 8 for the opening and sealing of the rear door 3 is achieved, which greatly reduces the cost of the entire vehicle, improves the safety performance of the vehicle during operation, and reduces the operating cost.

[0028] One end of a hook-shaped locking plate 5 is fixedly mounted on the rotating slider 4, and the other end of the locking plate 5 is hinged to the rear door 3. The hook-shaped locking plate 5 facilitates the connection between the rear door 3 and the rotating slider 4.

[0029] As a person skilled in the art, based on the technical inspiration of this embodiment, other power devices, such as cylinders, etc., can also be used, and the selection of these technical solutions should also be within the protection scope of the present invention.
