Description

Technical Field

[0001] The invention belongs to a road sweeping device, and in particular relates to a garbage lifting and introducing device of a sweeping vehicle. Background Art

[0002] Nowadays, almost all roads need to be cleaned and maintained, including outdoor roads, urban roads, residential areas, factory and school roads, etc. This is a very wide-ranging and large-scale job.

[0003] There is a technology that uses a larger diameter roller brush to act on the road surface and uses a hoist to cooperate to introduce the cleaned garbage into the box. However, this technology has not been widely promoted because the hoisting methods in the existing technology have some defects.

[0004] For example, in the utility model patent with application number 201120163365.8 and title: Road Sweeper Capable of Automatically Recycling Garbage, a traditional elevator is used. However, this requires many hoppers to rotate in a limited space. The shape and capacity of the hoppers are difficult to control, resulting in a large space being required to use the elevator. Once the garbage falls during the lifting process, there is no way to solve the problem.

[0005] For example, in the patent with application number 201210068619.7 and name: Electric Sweeper, a belt elevator is used to drive brushes and steel scrapers to lift garbage into the box along the lower shell of the lifting mechanism. However, the technical structure is complex. It is difficult to solve the problem of handling the entrance of garbage during the cleaning process. Once the lower shell of the lifting mechanism is completely closed, the cleaned garbage is difficult to enter the elevator, and once the lower shell of the lifting mechanism is opened, it is inevitable that garbage will fall out during the lifting process.

[0006] This requires improvements to the garbage lifting and introduction device of the sweeper to adapt to the environment inside the sweeper. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a garbage lifting and introducing device.

[0008] The present invention is achieved through the following technical solutions:

[0009] A garbage lifting and introducing device for a sweeper, the sweeper comprising a sweeping device and a collecting device for collecting swept objects, the garbage lifting and introducing device being used to introduce the garbage swept by the sweeping device into the collecting device, the garbage lifting and introducing device comprising a material guide plate and a garbage lifting and conveying mechanism, the material guide plate connecting the sweeping device and the garbage lifting and conveying mechanism, the garbage lifting and conveying mechanism comprising an intermediate plate, a plurality of alternately arranged material carrying plates, a chain for driving the material carrying plates, and a rotating bucket, the edges of the material carrying plates being tightly attached to the surface of the intermediate plate and circulate in the rotating bucket.

[0010] As a further improvement, the feed port of the rotating bucket is connected to the upper end of the guide plate.

[0011] As a further improvement, the chain includes an upper sprocket, a lower sprocket and a sprocket positioning device. The upper sprocket and the lower sprocket are used to drive the chain. The sprocket positioning device is located between the upper sprocket and the lower sprocket and is used to adjust the chain trajectory so that the edge of the loading plate is close to the surface of the middle plate and the inner surface of the bucket when loading garbage.

[0012] As a further improvement, the sprocket positioning device includes a first positioning sprocket and a second positioning sprocket, and the first positioning sprocket is located at the turning position of the middle plate.

[0013] As a further improvement, the position of the first positioning sprocket and / or the second positioning sprocket is adjustable, thereby achieving tensioning of the chain.

[0014] As a further improvement, the chain moves toward the collecting device on the side where the whole is located at the top.

[0015] As a further improvement, the position of the second positioning sprocket is adjustable, and the second positioning sprocket is located on the side where the entire chain is located below.

[0016] As a further improvement, it also includes ribs, which are located on both sides of the middle plate.

[0017] As a further improvement, the carrier plate includes a rigid plate body and a flexible edge.

[0018] As a further improvement, the inner surface of the rotating bucket includes a semi-cylindrical fitting portion, which fits with the edge of the carrier plate when the carrier plate moves.

[0019] As a further improvement, the material guide plate is liftable.

[0020] As a further improvement, the collecting device is located at the rear of the sweeper.

[0021] The beneficial effects of the present invention are: 1. The material carrying plate can lift and transport the garbage by relying on the middle plate and the rotating bucket; 2. It is convenient to cooperate with the sweeping device; 3. It has a simple structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Combine the following Figures 1 to 6 , an implementation mode of the present invention is described.

[0031] like Figure 3 As shown, it is a kind of sweeper. The sweeper comprises a sweeping device 1 and a trash bin 2 for collecting the swept objects. The garbage lifting and introducing device of the present invention is used to introduce the garbage swept by the sweeping device 1 into the trash bin 2. The garbage lifting and introducing device comprises a guide plate 3 and a garbage lifting and conveying mechanism 4. The retaining edge 44 is located on both sides of the middle plate 41. Figures 1 to 3 As shown, the guide plate 3 connects the sweeping device 1 and the garbage lifting and conveying mechanism 4, and the garbage lifting and conveying mechanism 4 includes an intermediate plate 41, a plurality of alternately arranged loading plates 42, a chain 48 for driving the loading plates 42, and a rotating bucket 43. The edges of the loading plates 42 are tightly attached to the surface of the intermediate plate 41 and circulate in the rotating bucket 43.

[0032] In order to allow the cleaned garbage to enter the rotating bucket 43, Figure 1 , Figure 3 As shown, the feed port of the rotating bucket 43 is connected to the upper end of the guide plate 3. After the cleaned garbage passes through the guide plate 3 and reaches the feed port above the rotating bucket 43, it enters the rotating bucket 43 due to gravity.

[0033] like Figures 1 to 4 As shown, the chain 48 includes an upper sprocket 45, a lower sprocket 46 and a sprocket positioning device 47. The upper sprocket 45 and the lower sprocket 46 are used to drive the chain 48. Figure 2 As shown, the sprocket positioning device 47 is located at the position where the middle plate 41 turns, and is used to adjust the trajectory of the chain 48 so that the edge of the carrier plate 42 is tightly attached to the surface of the middle plate 41 and the inside of the rotating bucket 43 when the garbage is loaded. The chain 48 moves toward the collecting device on the side where the whole is located at the top, that is, the carrier plate 42 is loaded with garbage at the position located at the upper part of the middle plate 41 and moves toward the garbage bin 2, that is, the carrier plate 42 will be loaded with garbage when it is located at the upper part, and must be tightly attached to the surface of the middle plate 41 and the inner surface of the rotating bucket 43 at these positions to complete the loading of the garbage. The first positioning sprocket 471 and / or the second positioning sprocket 472 can be configured to have a tensioning function, such as Figure 2 The second positioning sprocket 472 is provided with a tension adjustment bolt 473, and the position of the second positioning sprocket 472 can be fine-tuned by adjusting the tension adjustment bolt 473 to control the tension of the chain 48. The second positioning sprocket 472 is located on the side where the chain 48 is located at the bottom as a whole, so when adjusting, the position of the chain 48 at the bottom as a whole is affected, while the garbage is loaded at the upper side, so adjusting the second positioning sprocket 472 will not affect the loading and transportation of the garbage.

[0034] The loading plate 42 includes a rigid plate body and a flexible edge. The rigid plate body can be made of stainless steel to increase the load-bearing capacity of the loading plate 42, and the flexible edge can be made of wear-resistant rubber to reduce the possibility of falling from the gap during lifting.

[0035] like Figures 1 to 4 As shown, the inner surface of the rotating bucket 43 includes a semi-cylindrical fitting portion 431, which fits with the edge of the carrier plate 42 when the carrier plate 42 moves.

[0036] like Figure 1 As shown, the guide plate 3 is liftable. In order for the guide plate 3 to guide materials, its bottom must be close to touching the ground, which will hinder the cleaning of larger garbage. When the guide plate 3 can be lifted, the sweeping device 1 can sweep larger garbage when the guide plate 3 rises. When the guide plate 3 falls again, the larger garbage can be swept onto the guide plate 3. In specific use, the guide plate 3 can be set to be lifted and lowered indirectly. The solution that allows the guide plate 3 to be lifted and lowered intermittently is easy to implement, such as Figure 1It is recorded that a lifting device is arranged above the guide plate 3. The specific implementation method is easy to think of for those skilled in the art and will not be described in detail in the present invention.

[0037] When the sweeper starts and begins to sweep, the garbage swept by the sweeping device 1 will enter the rotating bucket 43 through the guide plate 3. Since the inner surface of the rotating bucket 43 includes a semi-cylindrical fitting portion 431, and fits with the edge of the carrier plate 42 when the carrier plate 42 moves. When the rotating bucket 43 passes through the rotating bucket 43, the garbage in the rotating bucket 43 will be carried on the carrier plate 42. When the carrier plate 42 leaves the rotating bucket 43, due to the angle setting of the carrier plate 42 and the middle plate 41, the garbage on the surface of the carrier plate 42 will fall close to the middle plate 41 due to its own gravity, and after passing through the middle plate 41, it will fall into the garbage bin 2. In the process of lifting garbage, even if a small amount of garbage falls, it will fall directly into the rotating bucket 43, and the garbage in the hopper will be lifted by the carrier plate 42 that passes through the rotating bucket 43. Compared with the prior art, the structure of the present invention is simpler and the conveying process is more stable.

[0038] Combine the following Figure 5 , Figure 6 Another embodiment of the present invention is described.

[0039] and Figures 1 to 4 The difference is that the garbage bin 2 is located in the middle of the sweeper, and the middle plate 41 includes a lower plate and an upper plate. The lower plate is inclined, and the middle plate 41 turns between the upper plate and the lower plate, and there is a curved connection between them; the middle plate 41 can be transformed into more sections or more complex shapes as needed. The two sections of this embodiment are only for illustration, and the middle plate 41 is not limited to two sections. The sprocket positioning device 47 is located at the connection between the upper plate and the lower plate between the upper sprocket 45 and the lower sprocket 46. This embodiment is used to illustrate that the length, direction, and distance of the middle plate 41 can be adjusted according to the change of the position of the garbage bin 2.

[0040] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
