Description

Technical Field

[0001] The utility model relates to a garbage transport vehicle. Background Art

[0002] Currently, the feed and discharge ports of food waste trucks are mostly independent, with the feed port typically located at the top of the waste container and the discharge port at the rear. When loading the waste, the feed port opens, and a lifting mechanism lifts the waste container and dumps it into the truck's storage container. To dump the waste, a hydraulic cylinder mechanism opens a hinged door at the rear of the container, allowing the waste to pour out. The container is fixed to the vehicle and cannot rotate.

[0003] The disadvantages of the existing structure are that the hinged door is often unable to be completely closed due to insufficient sealing performance or garbage jamming, resulting in unreliable sealing. During the operation of the garbage truck, spills and drips often occur, causing secondary pollution in the city. Secondly, the internal fluidity of the container is poor, and the input garbage accumulates below the feed port, making it difficult to fill. The space utilization rate is low, and the transportation efficiency is low. Thirdly, due to the adhesion of the garbage, it is not easy to unload completely during unloading. It is also necessary to add a push plate inside the garbage container, which complicates the structure, increases costs and failure points, and also brings problems such as leakage and garbage trapped behind the push plate that is difficult to clean. Utility Model Content

[0004] The utility model proposes a drip-proof rotary sealed garbage transport vehicle, the purposes of which are: 1. to solve the problem of leakage during transportation in existing garbage trucks; 2. to solve the problem of poor internal fluidity and low space utilization in the container; 3. to solve the problem of garbage sticking and being difficult to clean in the garbage container; 4. to solve the problem of complex structure, high manufacturing and maintenance costs of existing garbage trucks.

[0005] The technical solution of this utility model is as follows:

[0006] A drip-proof rotary sealed garbage transport vehicle comprises a vehicle body, a container for holding garbage is mounted on the vehicle body, and a rotating body connected to the container, wherein the rotating body is provided with an inlet and outlet;

[0007] The rotating body rotates relative to the vehicle body under the action of the rotary drive mechanism. When the inlet and outlet are rotated to the top of the rotating body, they are used as the inlet. When they are rotated to the bottom of the rotating body, they are used as the outlet.

[0008] As a further improvement of the drip-proof rotary sealed garbage transport vehicle: the container is a rotary drum, and the rotary drum serves as the rotary drive mechanism to drive the rotating body to rotate.

[0009] As a further improvement of the drip-proof rotary sealed garbage transport vehicle, the vehicle further comprises a blocking mechanism for blocking the rotation of the rotating body at a fixed position, the blocking mechanism comprising a first blocking portion and a second blocking portion;

[0010] When the rotating body rotates to the point where the material inlet and outlet are located at the top of the rotating body, the rotating body contacts the first blocking portion; when the rotating body rotates to the point where the material inlet and outlet are located at the bottom of the rotating body, the rotating body contacts the second blocking portion.

[0011] As a further improvement of the drip-proof rotary sealed garbage transport truck: the first blocking part is a horizontal frame located above the rotating body; when the inlet and outlet are located at the top of the rotating body, one side of the upper end of the rotating body is a straight line in contact with the bottom of the horizontal frame, and the other side is an outward convex arc connected to the straight line part, and the center of the arc coincides with the rotation axis of the rotating body; a wall panel assembly is provided at the bottom of the other side of the horizontal frame, and the bottom of the wall panel assembly is concave, and the concave part is used to contact and cooperate with the arc part on the rotating body to form an arc-shaped joint.

[0012] As a further improvement of the drip-proof rotary sealed garbage transport vehicle, a sealing device is provided at the arc-shaped joint.

[0013] As a further improvement of the drip-proof rotary sealed garbage transport vehicle, a cover plate installed by a rotating connection is provided on the cross frame.

[0014] As a further improvement of the drip-proof rotary sealed garbage transport truck: a driving cylinder and a rotating arm are also installed on the cross frame, one end of the driving cylinder is rotatably connected to the cross frame, and the other end is rotatably connected to one end of the rotating arm, the other end of the rotating arm is rotatably connected to the cross frame, and the cover plate is fixedly connected to the rotating arm.

[0015] As a further improvement of the drip-proof rotary sealed garbage transport vehicle: the rotating body and the rotary drum are rotationally connected, and the axis of the rotation connection coincides with the axis of rotation of the rotary drum relative to the vehicle body, and a spiral plate is provided on the inner wall of the rotary drum.

[0016] As a further improvement of the drip-proof rotary sealed garbage transport vehicle, a rotary sealing device is provided at the rotational connection between the rotating body and the container.

[0017] As a further improvement of the drip-proof rotary sealed garbage transport vehicle, a cover plate is provided at the inlet and outlet.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The utility model adopts a rotatable rotating body structure. The material is fed when the inlet and outlet are facing upwards and discharged when they are facing downwards. After the discharge is completed, the inlet and outlet are changed to face upwards to avoid leakage during transportation.

[0020] 2. The utility model further proposes a solution in which a rotary drum drives the rotating body to rotate. The rotary drum can not only drive the rotating body to switch the feeding and discharging states, but also promote the mixing and flow of internal garbage, avoiding the accumulation of garbage at the entrance after entering, thereby improving space utilization and transportation efficiency.

[0021] 3. The present invention also proposes a solution in which the rotating body can rotate relative to the rotary drum. In this solution, the rotary drum can continue to rotate while feeding and discharging materials, further improving the fluidity of the garbage and solving the problems of the container being unable to be filled and insufficient unloading.

[0022] 4. In the scheme in which the rotating body and the wall panel assembly constitute a separable material inlet and outlet container, the use of an arc-shaped joint solves the interference problem between the rotating body and the blocking mechanism. At the same time, it also provides a basis for the fixed cover sealing structure on the top, so that the cover does not need to rotate with the rotating body, which simplifies the structure and avoids the accumulation of spilled garbage on the cover, causing the cover to fail to close normally.

[0023] 5. By adding a spiral plate inside the rotary drum, the thrust on the garbage can be increased during rotation, driving the garbage to flow inward during feeding and move outward during discharging. This not only helps to solve the problem of garbage sticking and being difficult to clean, but also has a simpler structure than traditional pushing methods, and has lower manufacturing and maintenance costs.

[0029] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments. Example 1

[0030] like Figure 1 A drip-proof rotary sealed garbage transport vehicle includes a vehicle body, a container 1 for holding garbage mounted on the vehicle body, and a rotating body 2 connected to the container 1. The rotating body 2 can be bucket-shaped or other structure for garbage to pass through, and is provided with an inlet and outlet.

[0031] In this embodiment, the container 1 is a fixed container, and the rotating body 2 is installed at the rear of the container 1 and is rotatably connected to the container 1. A cover plate 4 is provided at the inlet and outlet, and its opening and closing is controlled by a cylinder or other mechanism.

[0032] Preferably, a rotary sealing device is provided at the rotational connection between the rotating body 2 and the container 1 , and the rotary sealing device includes an annular skeleton and a sealing ring.

[0033] In this embodiment, the rotating body 2 rotates relative to the garbage truck body under the action of an external rotary drive mechanism. The rotary drive mechanism includes a drive motor 3. A first gear mounted on the output shaft of the drive motor 3 meshes with a second gear mounted on the rotating body 2. As an alternative embodiment, the drive motor 3 may also drive the rotating body 2 via a transmission belt or other structure.

[0034] When the inlet and outlet are rotated to the top of the rotating body 2, they are used as the inlet, and when they are rotated to the bottom of the rotating body 2, they are used as the outlet. After discharging, the rotating body 2 is rotated again to a position where the inlet and outlet are facing upwards to avoid spillage during travel. Example 2

[0035] like Figure 2 This embodiment differs from the first embodiment in that the container 1 is a rotatable drum 100 (driven by an electric motor), and the rotating body 2 is fixedly mounted at the rear of the drum 100. The drum 100 serves as the rotary drive mechanism, driving the rotating body 2. Furthermore, a rotary support 5 is mounted on the vehicle body to support the drum 100.

[0036] The vehicle body is further provided with a blocking mechanism for blocking the rotation of the rotating body 2 , and the blocking mechanism includes a first blocking portion and a second blocking portion.

[0037] When the rotating body 2 rotates to the point where the inlet and outlet are at the top of the rotating body 2, they contact the first blocking portion, indicating a feeding state. When the rotating body 2 rotates to the point where the inlet and outlet are at the bottom of the rotating body 2, they contact the second blocking portion, indicating a discharging state.

[0038] In this embodiment, the rotary drum 100 not only drives the rotating body 2 to switch between feeding and discharging states, but also allows the waste inside to mix and flow, preventing waste from accumulating at the entrance. However, the mixing flow effect of this method is limited. If the efficiency of feeding and discharging is to be improved, it is necessary to add a device such as a spiral auger inside the rotary drum 100. Example 3

[0039] like Figure 3 This embodiment differs from the second embodiment in that the rotating body 2 and the rotary drum 100 are connected by a rotational connection, with the axis of this rotational connection coinciding with the axis of rotation of the rotary drum 100 relative to the vehicle body. A rotary seal 6 is also provided at the rotational connection. The inner wall of the rotary drum 100 is also provided with a spiral plate. This structure offers the advantage that, when the blocking mechanism blocks the rotating body 2 in the feeding or discharging position, the rotary drum 100 can continue to rotate, with the internal spiral plate pushing the garbage inward or outward, further improving fluidity. It also eliminates the need for structures such as a spiral auger, simplifying the structure.

[0040] Furthermore, if Figure 4 The first blocking part in the blocking mechanism is a cross frame 7 located above the rotating body 2, which is mounted on a column 13. A lifting device for lifting the trash can is also mounted on the column 13. A baffle 12 serving as a second blocking part is also provided on the column 13.

[0041] When the feed and discharge ports are located at the top of the rotating body 2, one side of the upper end of the rotating body 2 is linear, contacting the bottom of the horizontal frame 7, and the other side is an outwardly convex arc connected to the linear portion. The center of this arc coincides with the rotation axis of the rotating body 2. A wall panel assembly 10 is provided at the bottom of the other side of the horizontal frame 7. The bottom of this wall panel assembly 10 is concave, resembling a U-shaped structure when viewed from above. This concave portion is designed to contact and mate with the arc-shaped portion of the rotating body 2, forming an arc-shaped joint 11.

[0042] Preferably, a sealing device is provided at the arc-shaped seam 11 .

[0043] Furthermore, the cross frame 7 is provided with a cover plate 4 rotatably mounted thereon. A drive cylinder 8 and a pivot arm 9 are also mounted thereon. The drive cylinder 8 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. One end of the drive cylinder 8 is pivotally connected to the cross frame 7, and the other end is pivotally connected to one end of the pivot arm 9. The other end of the pivot arm 9 is pivotally connected to the cross frame 7, and the cover plate 4 is fixedly connected to the pivot arm 9.

[0044] When feeding garbage, the drive cylinder 8 opens the cover 4 while the drum 100 rotates clockwise. The horizontal frame 7 blocks the rotating body 2 and squeezes the arc-shaped portion with the wall assembly 10 to form a complete feeding container. The garbage entering the drum 100 is continuously moved forward by the spiral plate. When dumping garbage, the cover 4 remains closed and the drum 100 rotates counterclockwise. The arc-shaped portion can pass through the horizontal frame 7 without interfering with it. The rotating body 2 will move away from the horizontal frame 7 and wall assembly 10 until it touches the baffle 12. The garbage inside is moved outward by the spiral plate and finally poured out through the inlet and outlet. Example 4

[0045] This embodiment applies the blocking mechanism in the third embodiment to the structure of the second embodiment, and the specific structure will not be described in detail.

[0046] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
