Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a skid steer loader based on a spray dust suppression device. Background Technology

[0002] Mobile loaders are widely used in construction sites, mining operations, road maintenance, and other places due to their mobility, flexibility, and versatility. However, when loading and transferring materials such as earth, sand, gravel, and construction waste, they inevitably generate a large amount of dust, which seriously pollutes the working environment and poses a threat to the health of operators.

[0003] To suppress dust, existing skid steer loaders are typically equipped with spray dust suppression systems. These systems generally use a water pump to draw water from an onboard water tank and spray it as a mist through several nozzles located near the bucket to wet the dust. However, existing spray dust suppression solutions have significant shortcomings. First, most of these systems use traditional circular nozzles, which spray water mist in a dotted or cone-shaped pattern. When covering a wide work surface, gaps inevitably form between the multiple nozzles, creating dust suppression blind spots and resulting in unsatisfactory dust suppression effects.

[0004] Secondly, existing dust suppression equipment continuously consumes water from its tanks during operation. Since the water tanks on skid steer loaders have limited capacity, the water supply is quickly depleted under high-intensity operation. This forces operators to frequently interrupt work and drive the equipment to a fixed water source for replenishment, severely impacting the equipment's continuous operating time and overall construction efficiency, while also resulting in significant water waste.

[0005] Therefore, this utility model proposes a skid steer loader based on a spray dust suppression device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of blind spots, poor dust suppression effect, high water consumption and poor operation continuity of existing skid steer loaders with spray dust suppression equipment, this utility model aims to provide a skid steer loader with improved structure that can effectively solve the above problems based on spray dust suppression equipment.

[0007] This utility model provides a skid steer loader based on a spray dust suppression device, including: a body, a bucket, a base, a water tank, and a dust suppression assembly including a water pump, pipelines and a housing; as well as a wiper blade, a circulating pump, a filter tank, a first hose and a pressure buffer tank.

[0008] The outer shell has an integrally formed V-shaped guide groove and a recess inside, and the end of the recess forms a narrow slit nozzle.

[0009] Furthermore, the wiper blade is mounted on the machine body, the circulation pump is located inside the water tank, and the filter tank is connected in series on the pipeline of the first flexible hose connecting the wiper blade and the circulation pump; the pressure buffer tank is located between the water pump and the outer casing; the outlet of the water outlet inside the outer casing faces the inner wall of the V-shaped guide groove, and the V-shaped guide groove is connected to the inlet of the groove.

[0010] Preferably, the filter canister has at least one multi-stage filter screen inside.

[0011] Preferably, the circulating pump is provided with a first water inlet, and one end of the first hose is plugged into the first water inlet.

[0012] Preferably, the wiper blade is located at the bottom front end of the machine body.

[0013] Preferably, the dust suppression assembly includes an iron pipe and a second flexible hose; the water pump is connected to the inlet of the pressure buffer tank through the iron pipe, and the outlet of the pressure buffer tank is connected to the second flexible hose.

[0014] Preferably, the outer casing also has a second water inlet for the second hose to be connected to.

[0015] Preferably, the outer shell is fixed to the outer walls of both sides of the bucket and the outer wall of the front end of the base by fixing plates.

[0016] Preferably, the guiding surface of the V-shaped guide groove is curved.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up a water circulation system consisting of a scraper, a circulating pump and a filter tank, can collect ground moisture and filter it before re-injecting it into the water tank. This solves the problems of existing dust suppression equipment that rely entirely on external water replenishment, consume a lot of water, and need to frequently interrupt operations to add water. It achieves the technical effects of saving water resources, improving the continuity of operations and overall work efficiency.

[0019] 2. This utility model solves the problems of blind spots and incomplete dust suppression in the traditional circular nozzle dot spray by setting a V-shaped guide groove inside the shell and forming a narrow slit nozzle at the end, which shapes the high-pressure water flow and sprays it out. It achieves the technical effect of forming a wide fan-shaped fog field, suppressing dust without dead angles, and significantly improving the working environment.

[0020] 3. This utility model solves the problem of unstable spray pattern and inconsistent atomization effect caused by water pump pressure fluctuations by adding a pressure buffer tank in the dust suppression pipeline to stabilize the water flow output by the water pump. It achieves the technical effects of stable output water pressure, ensuring uniform and constant fan-shaped fog field, and improving the reliability of dust suppression. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 4 This utility model provides a skid steer loader based on a spray dust suppression device, which aims to solve the technical problems of blind spots, high water consumption, and poor operation continuity of existing skid steer loader dust suppression devices.

[0029] like Figure 1As shown, the skid steer loader based on a spray dust suppression system includes a body 1, a bucket 2 and a base 3 movably connected to the front end of the body 1, a water tank 4 fixedly installed on the body 1, and a dust suppression assembly 6. The dust suppression assembly 6 is the main structure for achieving the dust suppression function. The dust suppression assembly 6 includes a water pump 61, a pipeline in fluid communication with the water pump 61, and a housing 65 fixedly connected to the outer wall of the bucket 2 or the outer wall of the base 3 via a fixing plate 10. The body 1 serves as the load-bearing platform for the entire machine, the bucket 2 is used for loading and transferring materials, and the water tank 4 stores the water required for dust suppression.

[0030] The technical solution of this embodiment is that the skid steer loader is equipped with a water circulation and recovery structure and a fan-shaped mist field formation structure.

[0031] Specifically, refer to Figure 1 and Figure 2 The water recycling structure includes a wiper blade 11 fixedly connected to the front bottom of the machine body 1, a circulation pump 5 installed inside the water tank 4, and a filter tank 8 connected in series on a first flexible hose 7. One end of the first flexible hose 7 is connected to a water collection port behind the wiper blade 11, and the other end is plugged into a first water inlet 12 installed on the circulation pump 5. The filter tank 8 is hollow inside and contains multi-stage filter screens 9. The wiper blade 11 is used to collect ground water during the movement of the machine body 1. After the circulation pump 5 is started, it generates suction to draw water in through the first flexible hose 7. The water flows through the multi-stage filter screens 9 inside the filter tank 8 to remove impurities. Finally, the clean water is transported to the water tank 4 for storage, realizing the recycling of water.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The fan-shaped mist field formation structure is mainly achieved by the dust suppression component 6. The outlet of the water pump 61 is fixedly connected to the inlet of the pressure buffer tank 63 via an iron pipe 62. The pressure buffer tank 63 is used to absorb the pressure pulsations generated when the water pump 61 is working, so as to output a stable high-pressure water flow. The outlet of the pressure buffer tank 63 is in fluid communication with the second water inlet 66 on the outer shell 65 via a second hose 64. The outer shell 65 is firmly fixed to the outer walls of both sides of the bucket 2 and the outer wall of the front end of the base 3 by fixing plates 10. The interior of the outer shell 65 is provided with an integrally formed V-shaped guide groove 68 and a groove 69. The interior of the outer shell 65 is also provided with a water outlet 67, which is positioned directly opposite the inner wall of the V-shaped guide groove 68, which is a smooth curved surface. The outlet of the V-shaped guide groove 68 is directly connected to the inlet of the groove 69. When the high-pressure water jet is ejected from the outlet 67, it first impacts the curved inner wall of the V-shaped guide groove 68. Under the limiting guidance of the guide groove, the water jet is flattened and forms a flat stream. The flat stream then enters the groove 69 and is finally ejected at high speed from the narrow slit nozzle formed at the end of the groove 69, thus forming a wide-coverage fan-shaped mist field in the outside.

[0033] In a preferred embodiment, refer to Figure 2 Inside the filter tank 8, multiple layers of multi-stage filter screens 9 with decreasing pore sizes are fixed sequentially along the water flow direction. This tiered filtration structure can intercept impurities of different particle sizes in stages, improving filtration efficiency and extending the overall service life of the filter screens.

[0034] In another preferred embodiment, refer to Figure 1 The first inlet 12 is opened on the pump body of the circulating pump 5, and the end of the first hose 7 can be directly inserted into the first inlet 12 to form a quick and detachable connection, which facilitates the maintenance or replacement of the pipeline.

[0035] In another preferred embodiment, refer to Figure 1 The wiper blade 11 is a rubber plate with a certain degree of elasticity. It is fixed to the bottom front end of the machine body 1 by bolts to ensure that it can stick to the ground during operation to maximize water collection.

[0036] In another preferred embodiment, refer to Figure 3 The specific connection method of the dust suppression component 6 is as follows: the metal outlet pipe of the water pump 61 is directly welded to the iron pipe 62, and the other end of the iron pipe 62 is connected to the inlet end of the pressure buffer tank 63 through a threaded connection. The outlet end of the pressure buffer tank 63 is connected to the second hose 64 through a hose connector. This rigid-flexible pipeline layout ensures the strength and stability of the high-pressure section between the water pump and the buffer tank, while the flexibility of the second hose 64 facilitates connection with the outer casing 65 at different locations.

[0037] In another preferred embodiment, refer to Figure 3 and Figure 4 A second water inlet 66 is also provided on the outer casing 65, and the end of the second hose 64 is fastened to the second water inlet 66 by a clamp to form a reliable sealed connection.

[0038] In another preferred embodiment, refer to Figure 1 The outer shell 65 is fixed to key positions in the working area by fixing plates 10. Specifically, two outer shells 65 are fixed by fixing plates 10 welded to the outer walls of both sides of the bucket 2, and the other outer shell 65 is fixed by fixing plate 10 welded to the outer wall of the front end of the base 3, ensuring that the fan-shaped fog field can completely cover the main dust-generating area in front of and below the bucket.

[0039] In another preferred embodiment, refer to Figure 4 To make the water flow smoother in the V-shaped guide channel 68 and reduce energy loss, both guide surfaces of the V-shaped guide channel 68 are set as smooth concave arc surfaces.

[0040] The specific structure and manufacturing process of components such as body 1, bucket 2, base 3, and water tank 4, as well as the selection and control methods of water pump 61 and circulating pump 5, are all conventional technologies in this field. Those skilled in the art can select and design them according to actual needs, and will not elaborate further here.

[0041] Working Principle: When water circulation is required to replenish the water source, the operator starts the circulation pump 5 inside the water tank 4. As the machine 1 moves on the ground, the scraper 11 at its front bottom collects accumulated water or settled spray droplets from the ground. The negative pressure generated by the circulation pump 5 acts on the water collection port behind the scraper 11 through the first hose 7, drawing in the collected water. Before entering the circulation pump 5, the water must first flow through the filter tank 8 connected in series with the first hose 7. The multi-stage filter screen 9 inside the tank intercepts impurities such as sediment and particulate matter in the water. The purified water is then pressurized by the circulation pump 5, transported, and injected into the water tank 4, thus completing one cycle of water collection, purification, and reuse, reducing the need for external water supply.

[0042] When dust suppression spraying is required, the operator activates the water pump 61 in the dust suppression assembly 6. The water pump 61 draws water from the water tank 4 and delivers high-pressure water to the pressure buffer tank 63 via the iron pipe 62. The water flow is pressure-stabilized in the pressure buffer tank 63, eliminating pressure pulsations. Subsequently, the stabilized high-pressure water flow is distributed via the second hose 64 to the various outer casings 65 fixed to the bucket 2 and the base 3. The high-pressure water is sprayed at high speed from the outlet 67 inside the outer casing 65 onto the inner wall of the V-shaped guide channel 68, where it is molded into a flat water jet by the structural constraints of the V-shaped guide channel 68. This flat water jet then enters and fills the groove 69, finally exiting from the narrow slit nozzle at the end of the groove 69, forming a uniform, wide fan-shaped mist field that covers the working area in front of the bucket without any blind spots, effectively suppressing dust.
