Description

Technical Field

[0001] This utility model relates to the technical field of sweepers for loaders, and specifically discloses a sweeper for loaders. Background Technology

[0002] A loader sweeper is a cleaning device that combines the chassis and walking function of a loader with a dedicated sweeping device. This equipment utilizes the loader's powerful engine and maneuverability, combined with an efficient sweeping device, to quickly clean large areas of road surface and collect various types of garbage and debris.

[0003] In construction sites, mines, ports, and other places prone to dust, loader sweepers can effectively remove dust, reduce the impact of dust on the environment and people, protect the cleanliness of the surrounding environment, and improve air quality. Sweepers used in port and dock cleaning operations are mainly loader-mounted sweepers that use motors to directly drive the sweeping rollers, making them an economical and practical cleaning device.

[0004] However, the current connection between the sweeper and the loader is a rigid fixed connection. For example, the patent disclosed in announcement number CN221421780U discloses a sweeper collector suitable for skid steer loaders, which includes a cover box and a dust collection box. The cover box is located in front of the dust collection box. A sweeping roller brush is installed inside the cover box. A spray pipe is also installed inside the cover box. The spray pipe is connected to a water tank located at the rear of the machine through a water pipe and a water pump. Nozzles are installed at intervals on the spray pipe.

[0005] In the above setup, the loader's own weight is often transferred and pressed onto the sweeper during operation. When working on uneven ground, the sweeper will make a hard impact with the ground, causing the sweeper to deform and affecting its service life. Utility Model Content

[0006] To address the aforementioned shortcomings of the existing technology, this utility model provides a sweeper for loaders, which solves the problem that the sweeper's rigid fixed connection with the loader causes deformation and affects its service life.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A loader sweeper includes a sweeping bucket and a collecting bucket. The upper part of the collecting bucket is hinged to the upper part of the sweeping bucket. A first support wheel is provided at the lower front end of the collecting bucket, and a second support wheel is provided on the rear side wall of the sweeping bucket. The lower front side wall of the collecting bucket and the side wall of the sweeping bucket are connected by a hydraulic cylinder. The upper part of the sweeping bucket is hinged to the front end of a frame and is located within the frame. The upper rear end of the frame is hinged to a connecting assembly. The connecting assembly connects to the loader. The frame and connecting assembly design avoids a rigid connection between the sweeper and the loader, allowing for some movement between them, reducing deformation, and extending service life.

[0009] Preferably, the frame includes two parallel second connecting plates; the front ends of the two second connecting plates are connected by a first connecting plate; the rear ends of the two second connecting plates are connected by a third connecting plate; the upper front end of the sweeping hopper is hinged to the front part of the second connecting plate by a pin; the upper part of the collecting hopper is hinged to the sweeping hopper by a pin, and the collecting hopper is located inside the sweeping hopper; a first ear plate is fixedly provided on the side of the third connecting plate away from the second connecting plate; and an assembly is hinged to the upper side wall of the first ear plate.

[0010] Preferably, the connecting assembly includes a support plate; a hinge seat is fixedly disposed on the side wall of the support plate; the upper side wall of the first ear plate is hinged to the hinge seat; a second ear plate and a third ear plate are fixedly disposed on the side of the support plate away from the hinge seat; the second ear plate is disposed on the upper part of the support plate; and the third ear plate is disposed on the lower part of the support plate.

[0011] Preferably, a pad is fixedly provided on the side of the support plate near the first ear plate; the pad is located at the lower part of the support plate. This reduces the impact of the sweeping bucket on the support plate and reduces deformation.

[0012] Preferably, a limit component is provided between the rear end of the sweeping bucket and the frame to limit the range of rotation of the sweeping bucket on the frame.

[0013] Preferably, the limiting assembly includes a first limiting plate and a second limiting plate; the first limiting plate is fixedly disposed on the rear end side wall of the sweeping bucket; the second limiting plate is fixedly disposed on the third connecting plate and disposed at the lower part of the inner side wall of the third connecting plate; the second limiting plate is disposed below the first limiting plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By designing the frame and connecting components, a rigid connection between the sweeper and the loader is avoided, allowing for some movement between them, reducing deformation, and extending service life.

[0016] 2. By setting the limit components, the rotation range of the sweeper bucket on the frame is limited. Attached Figure Description

[0031] During cleaning operations, when the first support wheel 3 encounters a ground protrusion, it supports itself on the protrusion, causing the collection bucket 2 at the front of the sweeper to rise relative to the ground. The rear end of the sweeping bucket 1 can be limited to rotate using a limiting component, preventing collision between the upper part of the sweeping bucket 1 and the frame. Figure 1 and Figure 2 As shown; when the first support wheel 3 encounters a depression in the ground, the first support wheel 3 supports itself at the depression, causing the collection bucket 2 at the front end of the sweeper to descend relative to the ground. The lower rear end of the sweeping bucket 1 is blocked by the third connecting plate 6 of the frame, as shown. Figure 3 As shown; when the second support wheel 4 encounters a ground protrusion, the second support wheel 4 supports itself at the protrusion, causing the rear end of the sweeper's bucket 1 to lift upwards relative to the ground, as shown. Figure 4 As shown; when the second support wheel 4 encounters a depression in the ground, the second support wheel 4 supports itself at the depression, causing the rear end of the sweeper bucket 1 to descend relative to the ground, as shown. Figure 5 As shown, the sweeper floats freely up and down according to the ground conditions during operation, thereby reducing hard collisions with the ground, reducing the deformation of the sweeper, and extending the service life of the sweeper.
