Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention includes a first separation device that communicates with a discharge port of an air intake fan attached to a vehicle body; a dust container removably engaged with the lower part of the separation device to contain the separated dust; A dust collection port that communicates with the air intake of the fan and opens close to the ground surface, and a first separation device. A second separation device is installed to communicate with the engine to separate fine dust in the exhaust air. A cleaning method in which dust on the ground is sucked up by a rotating fan and stored in a dust container. It is related to the machine.

0002

[Conventional technology]

Conventionally, this type of cleaning machine uses a separator to separate dust and remove the removed air directly into the atmosphere. It was emitting. In addition, if the structure is covered with a cover to prevent engine noise, The heat dissipation of the gin has decreased, and the cooling effect of the cooling fan alone is insufficient. there was.

0003

[Problem that the idea aims to solve]

The problem we are trying to solve is to cover the engine with a cover to prevent noise from the cleaner. This is because the cooling effect of the engine decreases.

0004

[Means to solve the problem]

This invention uses a separator to separate the dust from the dust-laden air that is sucked in, and then discharges the dust. A filter is installed to further filter the wind, and this exhaust air is routed to the outer periphery of the engine cylinder. A cooling air path will be provided to guide the

[0005]

[Effect]

This invention uses suction air that sucks up dust on the ground using a suction fan, and uses a separator to remove dust. The exhaust air is further filtered and sent to the engine to cool it. Use as a breeze.

[0006]

【Example】

Figure 1 shows the entire cleaning machine, and a car body 3 equipped with wheels 1, 1... An air intake fan 7 that rotates by the drive of the engine 5 is installed, and an air intake port 9 that communicates with the air intake port 9 of the air intake fan 7 is installed. The duct 11 has a dust collection port 12 open close to the ground surface.

[0007] A first separation device 13 is provided at the rear of the vehicle body 3, and an air intake fan is provided through a duct 15. It communicates with the discharge port 17 of 7. A dust container 19 is attached at the bottom of the first separator 13. It is attached removably. The first separation device 13 is configured as follows. vinegar That is, the duct 15 opens in the circumferential direction in the cylindrical outer cylinder 21 and is threaded in the circumferential direction. It is provided so as to guide the air along a wire mesh wall 23 provided in a spiral shape.

[0008] A second separation device 25 is provided in the center of the outer cylinder 21 . In other words, the outer cylinder A dust collection chamber 27 having a conical lower part of a cylinder is provided in the center of the dust collection chamber 21. An opening/closing lid 29 is provided at the bottom of 7. A ceiling portion 31 that covers the upper part of the outer cylinder 21; A large number of centrifugal separators 35 are fixed at both ends between the dust collection chamber 27 and the upper surface 33. . As shown in Fig. 2(a), the centrifugal separator 35 has an outer cylinder 37 with a conical portion formed at the bottom. , an inner cylinder 39 is provided at the center of the outer cylinder 37, and a spiral blade 41 is fixed between the outer cylinder 37 and the inner cylinder 39. penetrates the upper surface of the dust collection chamber 27 and is fixed, and the inner cylinder 39 penetrates the ceiling part 31 and is fixed. ing.

[0009] The upper part of the ceiling part 31 is covered by a ventilation cover 43, and the front part of the ventilation cover 43 is A filter 45 is provided in the opening facing the engine 5, and a cooling air passage 46 is provided. It is formed. Covering the top and sides of the blower cover 43 and the engine 5, A main body cover 49 is provided with an air exhaust port 47 on the side surface. Body cover 49 A handle 51 is provided on the rear surface.

0010 During work, air is sucked by the suction force of the air intake fan 7, which is rotated by the engine 5. The air sucked from the duct 15 is sent to the first separation device 13 through the duct 15, As it descends while rotating inside the outer cylinder 21 through the air passage surrounded by the wire mesh wall 23, Then, the dust falls and is collected in the dust container 19, and the exhaust air passes through the wire mesh 23 and is sent to the second part. Enter the separating device 25.

[0011] This exhaust air flows from the upper end of the outer cylinder 37 of the centrifugal separator 35 to the spiral blades 41 inside the outer cylinder 37. Therefore, it descends while rotating, and the dust in the exhaust air is separated by centrifugal force and collected in the dust collection chamber 27. The exhaust air passes through the inner cylinder 39 and enters the air blower cover 43, and then passes through the filter. 45, fine dust is removed, and the exhaust air passes through a cooling air passage 46 and is blown to the engine 5. It cools the cylinder (not shown) of the engine 5 and blows air from the exhaust port 47. It is released into the air. The worker holds the handle 51 and pushes the vehicle body 3 forward. , which sucks the dust on the ground and stores it in the dust container 19.

0012

[Effect of the idea]

According to the present invention, the exhaust air from the cleaning machine is used to cool the engine. Cover the engine to prevent noise and prevent the engine from overheating. It is something that can be done.
