[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a sweeper attachment for a forklift, which includes a closed housing 1, a roller brush 2, a collection hopper 3, a spray dust removal device 4, a set of guide wheels 5, a forklift fixing component 7, and a bottom sealing door 9. The closed housing 1 is welded from carbon steel plate. The two corresponding side plates of the closed housing 1 are respectively provided with an opening. The two ends of the roller brush 2 are located at the corresponding openings of the closed housing 1. The two ends of the roller brush 2 are connected to the side plates of the closed housing 1 through bearings with seats 6. One end of the roller brush 2 is provided with a hydraulic motor 12 to drive the roller brush to rotate, so as to drive the roller brush 2 to rotate to achieve the purpose of sweeping. The enclosed housing 1 has a cavity at the front of the roller brush 2 forming a garbage collection hopper 3 for storing swept ground garbage. For easy dumping, a bottom sealing door 9 is provided at the bottom of the hopper, which is connected to the enclosed housing 1 via a hinge 10. A hydraulic cylinder 8 is located on the outside of the enclosed housing 1 to control the opening and closing of the bottom sealing door 9, with the extension end of the cylinder rod of the hydraulic cylinder 8 connected to the bottom sealing door 9. During cleaning operations, the roller brush rotates within a closed space, significantly reducing dust. The top of the enclosed housing 1 is equipped with a spray dust suppression device 4 and a forklift fixing component 7, while the travel guide wheel assembly 5 is located at the bottom of the enclosed housing 1.

[0024] like Figure 2 , Figure 3 As shown, the spray dust suppression device 4 includes a water tank 41, a spray pump 42, a spray pipe 43, and nozzles 44. The water tank 41 is located on the top of the enclosed housing 1. One end of the spray pump 42 is connected to the water tank 41 via a pipe, and the other end is connected to the spray pipe 43 via a pipe. The spray pipe 43 is equipped with multiple high-pressure nozzles 44. The spray pump 42 draws water from the water tank 41, pressurizes it, and then inputs it into the pipe. The water is then sprayed out in a cone-shaped atomized band through the nozzles 44, thus forming a dust-suppressing water mist band around the sweeper. This effectively suppresses dust, and the water mist also moistens the ground after landing, further reducing dust. In particular, the number of nozzles or the position of the nozzles can be increased or decreased, and the size of the spray band can be adjusted according to the range of dust, to adapt to different dust suppression requirements. By setting up the spray dust suppression device, the dust suppression effect can be further improved.

[0025] like Figure 3As shown, the walking guide wheel group 5 includes a guide walking wheel 51 and a support wheel 52. The guide walking wheel 51 is located at the front of the closed housing 1, and there are two support wheels 52. The two support wheels 52 are respectively located on the rear sides of the closed housing 1. One guide walking wheel and two support wheels are arranged in a triangle at the bottom of the closed housing.

[0026] The function of the walking wheel set 5 is to ensure that the roller brush 2 installed on the machine housing 1 maintains a constant height between it and the ground. When the roller brush wears down and the diameter becomes smaller, the position of the square bearing with seat can be lowered so that the roller brush 2 is always in contact with the ground and the ground can be cleaned.

[0027] like Figure 4 , Figure 5 As shown, the forklift mounting component 7 includes two insertion holes 71 that mate with the forks. At least one fastening bolt 72 is provided on the top wall of each insertion hole, with the bolt extending into the insertion hole. When installing this attachment on an idle forklift, the forklift's forks are inserted into the corresponding insertion holes, and then the fastening bolt is rotated to securely connect the forks to the attachment.

[0028] To further improve the firmness of the connection between the attachment and the forklift, a pressure plate (not shown in the figure) is provided at the free end of the screw of the fastening bolt 72 to strengthen the connection between the attachment and the forklift. Since the contact area between the pressure plate 72 and the forklift is increased, the forklift is pressed by the pressure plate when the fastening bolt is rotated.

[0029] This utility model of a sweeper attachment for forklifts solves the problem of idle forklifts in railway freight yards, enabling forklifts to have both handling and sweeping functions. Compared with purchasing dedicated sweepers in the past, it saves 90% of the cost and greatly improves the sweeping efficiency, increasing the single-shift operating area from 40,000 square meters to 100,000 square meters.

[0030] The above description is merely an illustration of some principles of this utility model. This specification is not intended to limit this utility model to the specific structure and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this utility model.

[0031] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
