Description

Technical Field

[0001] This utility model relates to the field of slope greening spraying technology, specifically a slope greening spraying device. Background Technology

[0002] Hydroseeding technology is one of the most widely used, quick and effective, and relatively low-cost ecological restoration technologies in the world. Its principle is to use hydroseeding equipment to mix plant seeds, water, fiber mulch, adhesives, fertilizers, nutrient soil, soil stabilizers, soil conditioners, etc. in a certain proportion, and then spray them onto the original landform surface where the native vegetation has been destroyed through a special spraying system (dedicated hydroseeding machine), thereby forming a uniform matrix covering layer. Hydroseeding equipment is frequently used in slope greening.

[0003] Most existing hydroseeding devices have fixed nozzles, resulting in a single type of sprayed slurry that cannot be flexibly adjusted according to the actual conditions of the slope, such as distance and slope.

[0004] Therefore, there is an urgent need to design a slope greening spraying device that can solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a slope greening spraying device. To achieve the above purpose, this utility model provides the following technical solution:

[0006] A slope greening spraying device includes a loading vehicle, a storage box on the loading vehicle, an output port of the storage box connected to a pump body input port, a hose connected to the pump body output port, a connector at one end of the hose, a spraying sleeve connected to the connector by a thread, a first adjustment component on the spraying sleeve, and a support frame on the loading vehicle, with a second adjustment component at the top of the support frame.

[0007] Furthermore, the spraying sleeve has a conical output channel inside, which is connected to the connector, and the upper lip is fixedly connected to the side of the spraying sleeve near the output port of the conical output channel.

[0008] The above technical solution enables a quick, sealed, and detachable connection between the hose and the spraying sleeve. The spraying sleeve and the inside of the hose form a channel for slurry flow, while the conical output channel converts the pressure energy of the slurry into kinetic energy, forming a high-speed, concentrated jet.

[0009] Furthermore, the first adjustment component includes a lower lip arranged parallel to the upper lip. The lower lip is fixedly connected to a rotating shaft. One end of the rotating shaft passes through the side wall of the spraying sleeve and is connected to a passive gear. The passive gear has a plurality of teeth. The driving gear has a plurality of slots that match the teeth. The passive gear meshes with the driving gear. The driving gear has a rotating shaft on one side near the spraying sleeve. The rotating shaft is connected to the spraying sleeve through a bearing seat. Both ends of the rotating shaft are connected to the spraying sleeve through bearing seats. A rotating sealing ring is provided at the point where the rotating shaft passes through the spraying sleeve.

[0010] With the above technical solution, the lower lip is a movable cutting edge, and by changing its relative position with the upper lip, the shape of the ejected fan can be controlled.

[0011] Furthermore, the spraying sleeve has a threaded cylinder on one side near the drive gear, and the threaded cylinder is connected to a T-shaped rod by a thread. The diameter of the T-shaped rod is larger than the diameter of the slot, and a sealing gasket is provided on the outside of the lower lip near the driven gear.

[0012] The above technical solution controls the position of the lower lip after adjustment by assembling the T-shaped sensor and the threaded cylinder.

[0013] Furthermore, the second adjustment component includes a retaining ring arranged along the circumference of the hose, and connecting shafts are symmetrically arranged on both sides of the retaining ring, one of which is connected to a rotary motor;

[0014] The above technical solution drives the fixed ring and nozzle to make pitching motion in the vertical plane to adjust the spray angle and cover slopes of different heights.

[0015] Furthermore, the bottom end of the support frame is provided with an electric push rod;

[0016] The working height of the nozzle is adjusted using the above technical solution.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a slope greening spraying device to achieve the following effects: By incorporating a first adjustment component consisting of a movable lower lip and a fixed upper lip, and employing gear transmission, the operator can precisely and effortlessly adjust the width of the spraying slits. This allows for flexible adjustment of the thickness and range of the sprayed fan-shaped slurry curtain according to the actual conditions of the slope, enabling switching between "long range" and "wide coverage" modes, fundamentally solving the problem of poor adaptability of traditional fixed nozzles.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0025] Please see Figure 1-3 This embodiment provides a slope greening spraying device, including a loading vehicle 1. The loading vehicle 1 is equipped with a storage box 101. The output port of the storage box 101 is connected to the input port of a pump body 102. The output port of the pump body 102 is connected to a flexible hose 103. One end of the flexible hose 103 is equipped with a connector 104, which is threadedly connected to a spraying sleeve 105. The spraying sleeve 105 is equipped with a first adjusting component 2. The loading vehicle 1 is also equipped with a support frame 3, and the top of the support frame 3 is equipped with a second adjusting component 4.

[0026] When using the slope greening spraying device, first add the material to the storage tank 101 and mix. The operator drives the loading vehicle 1 to a suitable position, starts the electric push rod of the support frame 3 to lift the nozzle, and starts the rotary motor 403 of the second adjustment component 4 to adjust the spraying angle. According to the slope characteristics, rotate the drive gear 204 of the first adjustment component 2 to adjust the gap between the lower lip 201 and the upper lip 1052, and then tighten the T-shaped rod 206 to lock the drive gear 204. Start the pump body 102, and the slurry is sprayed out from the narrow slit through the hose 103 and the conical output channel 1051 of the spraying sleeve 105 to cover the slope. While the pump body 102 is working, it controls the rotary motor 403 to make the nozzle pitch and scan the slope. After completing one area, the loading vehicle 1 moves to the next area and repeats the operation until the slope spraying is completed.

[0027] like Figure 1 and Figure 2 and Figure 3 As shown, the spraying sleeve 105 has a conical output channel 1051 inside, which is connected to the connector 104. An upper lip 1052 is fixedly connected to the side of the spraying sleeve 105 near the output port of the conical output channel 1051. The first adjusting component 2 includes a lower lip 201 parallel to the upper lip 1052, which is fixedly connected to a rotating shaft 202. One end of the rotating shaft 202 passes through the side wall of the spraying sleeve 105 and connects to a driven gear 203. The driven gear 203 has several teeth, and the driving gear 204 has several slots that match the teeth. 03. The driving gear 204 is engaged with the spraying shaft 202. Both ends of the shaft are connected to the spraying sleeve 105 via bearing seats. The driving gear 204 has a rotating shaft on its side near the spraying sleeve 105, and the rotating shaft is connected to the spraying sleeve 105 via a bearing seat. A rotary sealing ring is provided at the penetration point between the rotating shaft 202 and the spraying sleeve 105. A threaded cylinder 205 is provided on the side of the spraying sleeve 105 near the driving gear 204. The threaded cylinder 205 is connected to a T-shaped rod 206 via threads. The diameter of the T-shaped rod 206 is larger than the diameter of the groove. A sealing gasket is provided on the outer side of the lower lip 201 near the driven gear 203.

[0028] Based on the slope characteristics of this operation, such as distance and slope, the operator manually rotates the drive gear 204 of the first adjustment component 2 to adjust the gap between the lower lip 201 and the upper lip 1052. For example, if long-range projection is needed, the gap is reduced to obtain a thick and narrow fan shape with a long range; if wide coverage is needed, the gap is increased to obtain a wide and thin fan shape with a large coverage area. After adjustment, the T-shaped rod 206 is tightened to lock the drive gear 204. This is achieved by the T-shaped rod 206 engaging with the threaded cylinder 205, restricting the rotation of the passive gear 203, and thus locking the drive gear 204. This ensures the stability of the fan shape during spraying. The pump body 102 is then started to pump the slurry from the storage tank 101. The slurry is transported through the hose 103, accelerated through the conical output channel 1051 of the spraying sleeve 105, and finally sprayed out from the narrow gap formed by the upper lip 1052 and the lower lip 201, forming a fan-shaped slurry curtain that conforms to the preset shape and evenly covers the slope.

[0029] like Figure 1 and Figure 2 As shown, the second adjustment assembly 4 includes a retaining ring 401 arranged along the circumference of the hose 103, and connecting shafts 402 symmetrically arranged on both sides of the retaining ring 401, one of which is connected to a rotary motor 403.

[0030] While the pump body 102 continues to work, the rotating motor 403 is slowly controlled to make the nozzle move up and down at a uniform speed, scanning the entire slope like a fan to ensure uniform spraying without dead angles.

[0031] like Figure 1 As shown, the bottom end of the support frame 3 is equipped with an electric push rod.

[0032] Activate the electric push rod at the bottom of the support frame 3 to lift the nozzle, which is the whole assembly consisting of connector 104, spray sleeve 105, etc., to a suitable height.

[0033] The working process of this utility model is as follows: When using this slope greening spraying device, firstly, the spraying material is added to the storage tank 101 in proportion for mixing. The operator drives the loading vehicle 1 to the optimal working position in front of the slope to be greened, activates the electric push rod at the bottom of the support frame 3, and raises the nozzle (which can be considered as the nozzle-related part, consisting of the connector 104, spraying sleeve 105, etc.) to a suitable height. Then, the rotary motor 403 of the second adjustment component 4 is activated to adjust the initial spraying angle of the nozzle to be roughly aligned with the slope surface.

[0034] Based on the slope characteristics of this operation, such as distance and slope, the operator manually rotates the drive gear 204 of the first adjustment component 2 to adjust the gap between the lower lip 201 and the upper lip 1052. For example, if long-range spraying is required, the gap is reduced to obtain a thick and narrow fan shape with a long range; if wide coverage is required, the gap is increased to obtain a wide and thin fan shape with a large coverage area. After adjustment, the T-shaped rod 206 is tightened to lock the drive gear 204. This locks the drive gear 204 by engaging with the threaded cylinder 205 through the T-shaped rod 206, restricting the rotation of the driven gear 203, and thus locking the drive gear 204, ensuring the stability of the fan shape during spraying.

[0035] The pump body 102 is started to pump out the slurry in the storage tank 101. The slurry is transported through the hose 103 and accelerated through the cone-shaped output channel 1051 of the spraying sleeve 105. Finally, it is sprayed out from the slit formed by the upper lip 1052 and the lower lip 201 to form a fan-shaped slurry curtain that conforms to the preset shape and evenly covers the slope.

[0036] While the pump body 102 continues to operate, the rotary motor 403 is slowly controlled to make the nozzle move up and down at a uniform speed, scanning the entire slope like a fan to ensure uniform spraying without blind spots. After spraying one area, the loading vehicle 1 slowly moves to the next adjacent area and repeats the steps until the entire slope is sprayed.

[0037] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. Among them, the electric push rod and rotary motor are existing mature technologies, so their principles will not be elaborated. The control method is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple circuit connection. It is common knowledge in the field, so this application will not explain the control method and circuit connection in detail.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
