Description
Technical Field
[0001] This utility model belongs to the field of desert control equipment technology, specifically a traction-type desert concrete spreading machine. Background Technology
[0002] With desertification becoming increasingly serious, desertification control has become an important task for environmental protection and sustainable development. Water conservation is a key aspect of desertification control.
[0003] Traditional desertification control methods rely on manual or simple mechanical sand spreading, which suffers from low efficiency, uneven thickness, and poor water retention. Current technologies lack specialized equipment for precise application of water-retaining sand layers, and particularly lack integrated solutions for controlling layer thickness (15mm) and underground material placement. The market currently lacks efficient, convenient, and precise equipment for laying water-retaining materials, resulting in slow progress in desert water conservation efforts and failing to meet the needs of large-scale desertification control. Therefore, developing a new type of traction-type desert sand spreading machine is of great significance for improving desertification control efficiency and enhancing the desert ecological environment. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a traction-type desert concrete laying machine with the advantage of high laying efficiency.
[0005] This utility model provides the following technical solution: a traction-type desert concrete spreading machine, including a storage bin. Support plates are fixedly connected to both sides of the bottom of the storage bin. Fixing blocks are fixedly connected to the front and rear sides of the bottom of the support plates. Rollers are rotatably connected to the surface of the fixing blocks. Seven hollow metal triangular plowshares are connected to the bottom of the storage bin, evenly distributed at the bottom. A spreading hole is opened on the left side of each hollow metal triangular plowshare. The top of the storage bin is connected by bolts. A top plate is fixedly connected, and a spiral conveying rod is rotatably connected inside the top plate. There are seven spiral conveying rods, the bottom of which extends into the interior of a hollow metal triangular plowshare. The spiral conveying rod is in contact with the inner wall of the hollow metal triangular plowshare. A first gear is fixedly connected to the top of the spiral conveying rod, and any two adjacent first gears mesh with each other. A reduction motor is fixedly connected to the front of the storage bin, and a second gear is fixedly connected to the output end of the reduction motor. The second gear meshes with the first gear located on the front.
[0006] The top plate is internally fixedly connected to a bearing, with the outer ring of the bearing fixedly connected to the top plate and the inner ring of the bearing fixedly connected to the screw conveyor rod. A sealed shaft cover is provided inside the bearing.
[0007] The beneficial effects of this utility model are as follows:
[0008] 1. This utility model utilizes seven hollow metal triangular plowshares evenly distributed at the bottom of the storage silo, in conjunction with a screw conveyor rod, to achieve efficient underground distribution of water-retaining sand. The structural design of the hollow metal triangular plowshares allows them to naturally cut through the sand layer during movement. The material distribution hole on their left side, in conjunction with the contact movement of the screw conveyor rod, creates a continuous pushing force, causing the water-retaining sand to flow evenly from the storage silo into the ground. The meshing transmission of adjacent first gears, combined with the drive of a geared motor, ensures that the seven screw conveyor rods operate synchronously, avoiding the uneven torque problems that may occur with single-rod drive, thus ensuring a consistent output from each hollow metal triangular plowshare. This integrated design combines storage, conveying, and distribution functions into one unit, enabling the laying of large-area water-retaining sand layers without manual intervention. It effectively solves the problems of low efficiency and uneven thickness associated with traditional manual sand spreading, and the device boasts the advantage of high distribution efficiency.
[0009] 2. This utility model provides a reliable dust and sand barrier for the internal transmission components through a protective cover. Sand and dust in desert environments can easily penetrate the gaps between gears and motors, leading to decreased transmission efficiency or even equipment failure. The enclosed structure of the protective cover completely encloses the first gear, the reduction motor, and the second gear. Combined with its fixed connection to the top plate, this effectively prevents sand and dust from entering the transmission system, extending the equipment's service life. Furthermore, the protective cover prevents operators from accidentally contacting the high-speed rotating gears, improving on-site safety. Its design does not affect the heat dissipation of the reduction motor, ensuring stable transmission performance during long-term operation. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] like Figures 1 to 4 As shown, the traction-type desert concrete spreader of this embodiment includes a storage bin 1. Support plates 2 are fixedly connected to both sides of the bottom of the storage bin 1. Fixing blocks 3 are fixedly connected to the front and rear sides of the bottom of the support plates 2. Rollers 4 are rotatably connected to the surface of the fixing blocks 3. Hollow metal triangular plowshares 5 are connected to the bottom of the storage bin 1. There are seven hollow metal triangular plowshares 5, evenly distributed at the bottom of the storage bin 1. A spreading hole 6 is opened on the left side of each hollow metal triangular plowshare 5. A top plate 7 is fixedly connected to the top of the storage bin 1 by bolts. Seven spiral conveying rods 8 are rotatably connected inside the top plate 7. The bottom of each spiral conveying rod 8 extends into the interior of the hollow metal triangular plowshare 5, fitting against the inner wall of the hollow metal triangular plowshare 5. A first gear 9 is fixedly connected to the top of each spiral conveying rod 8, and any two adjacent first gears are connected in series. The first gear 9 meshes with the first gear 9 located on the front of the storage bin 1. The storage bin 1 is fixedly connected to the front of the first gear 9. The storage bin 1 is 4000mm long, 4000mm wide, and 3100mm high. The opening height of the material distribution hole 6 is 15mm. During operation, water-retaining sand enters the hollow metal triangular plowshare 5 from the storage bin 1 and is transported to the desert underground through the material distribution hole 6. A 4000mm wide horizontal overlap can be formed into a 15mm thick water-retaining sand layer in one go, ensuring the width and thickness of the water-retaining sand layer, improving the water retention effect, and greatly improving the laying efficiency. Compared with the traditional manual laying method, it can save a lot of manpower and time costs and meet the needs of large-scale desert control projects. The angle of the hollow metal triangular plowshare 5 into the sand is 30°±2° (to ensure that the soil disturbance is minimized).
[0017] refer to Figure 1 A protective cover 12 is fixedly connected to the top of the top plate 7. The first gear 9, the reduction motor 10, and the second gear 11 are all located inside the protective cover 12.
[0018] This embodiment provides a reliable dust and sand barrier for the internal transmission components through the protective cover 12. Sand and dust in desert environments can easily penetrate the gaps between gears and motors, leading to decreased transmission efficiency and even equipment failure. The enclosed structure of the protective cover 12 completely encloses the first gear 9, the reduction motor 10, and the second gear 11. Combined with its fixed connection to the top plate 7, this effectively prevents sand and dust from entering the transmission system, extending the equipment's service life. Furthermore, the protective cover 12 prevents operators from accidentally contacting the high-speed rotating gears, improving on-site safety. Its design does not affect the heat dissipation of the reduction motor 10, ensuring stable transmission performance during long-term operation.
[0019] refer to Figure 1 The storage bin 1 has observation windows 15 on both sides of its front.
[0020] This embodiment provides operators with a visual channel for real-time monitoring of the internal material status through observation windows 15 on both sides of the front of the storage silo 1. The observation windows 15 allow direct observation of the water-retaining sand's quantity, flow status, and whether there are any blockages, preventing interruptions in material distribution due to an empty storage silo 1 or material clumping. In desert remediation sites, environmental conditions are complex, and frequent manual equipment checks are time-consuming and prone to introducing sand and dust. The observation windows 15 allow operators to quickly assess the equipment's operating status without stopping the machine, promptly adjusting the feeding frequency or clearing blockages, significantly improving construction efficiency. The windows are made of impact-resistant transparent material, capable of withstanding the wind and sand impacts of the desert environment, ensuring long-term reliability.
[0021] refer to Figure 1 The top of the top plate 7 is fixedly connected to the four sides with lifting rings 14.
[0022] This embodiment significantly improves the ease of transportation and installation of the equipment through the design of lifting rings 14 around the top of the top plate 7. In desert control projects, equipment often needs to be transported to remote construction areas by hoisting. The lifting rings 14 allow for the rapid hoisting of the concrete placing boom using a crane, avoiding damage to the equipment structure caused by traditional handling methods. The distribution of the lifting rings 14 is mechanically optimized to ensure the equipment's center of gravity is balanced during hoisting, reducing the risk of swaying. Furthermore, during the equipment installation and commissioning phase, the lifting rings 14 can assist in adjusting the equipment's posture, ensuring that the hollow metal triangular plowshare 5 maintains the correct soil-penetrating angle with the ground, thereby guaranteeing consistent concrete placement results. The lifting rings are made of high-strength steel, capable of withstanding the overall weight of the equipment and the impact forces during hoisting.
[0023] refer to Figure 1 The top plate 7 has feeding ports on both sides of the top, and the top plate 7 has cover plates 13 hinged to both sides of the top, which are used in conjunction with the feeding ports.
[0024] This embodiment achieves rapid replenishment and sealed storage of water-retaining sand through the cooperation design of the feeding port at the top of the top plate 7 and the hinged cover plate 13. The position and size of the feeding port are optimized to accommodate rapid feeding by loaders or conveyors, reducing downtime. After feeding, the hinged cover plate 13 can tightly cover the feeding port, achieving a seal through gravity or a simple locking device, effectively preventing desert sand from entering the storage bin 1 and contaminating the water-retaining sand. This design balances feeding efficiency and material protection requirements, and is especially suitable for windy desert environments. The opening angle of the cover plate 13 is adjustable, allowing operators to choose the optimal feeding method according to site conditions, while avoiding material spillage and waste during the feeding process.
[0025] refer to Figure 1 A traction frame 16 is fixedly connected to the right side of the storage bin 1.
[0026] This embodiment utilizes the towing frame 16 on the right side of the storage bin 1 to enable the equipment to be quickly connected to various traction power sources, such as tractors, achieving flexible mobile operations. The towing frame 16 has the structural strength to withstand the bumps and tension in desert terrain, and its connection parts can also adopt universal joints or adjustable structures, allowing the equipment to adapt to different slopes and dune shapes during travel.
[0027] refer to Figure 2 Both sides of the bottom of the inner wall of the storage bin 1 are fixedly connected with guide ramps 17.
[0028] In this embodiment, a flow-guiding ramp 17 at the bottom of the inner wall of the storage silo 1 guides the water-retaining sand towards the inlet of the hollow metal triangular plowshare 5, preventing material accumulation at the bottom of the silo. The inclination angle and surface treatment of the flow-guiding ramp 17 are optimized to accelerate material flow using gravity, reducing residue and agglomeration. In the high-temperature environment of the desert, water-retaining sand is prone to increased viscosity due to moisture evaporation; the design of the flow-guiding ramp 17 effectively reduces the risk of material retention, ensuring continuous and stable discharge.
[0029] refer to Figure 2 The top plate 7 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the top plate 7, while the inner ring of the bearing is fixedly connected to the screw conveyor rod 8. The bearing is internally equipped with a sealed shaft cover.
[0030] This embodiment provides a low-friction, high-sealing support structure for the screw conveyor 8 through the combination of a bearing and a sealed shaft cover inside the top plate 7. The outer ring of the bearing is fixed to the top plate 7, and the inner ring is connected to the screw conveyor 8, ensuring coaxiality and stability during transmission and reducing vibration and noise. The sealed shaft cover design effectively prevents sand and dust from entering the bearing, avoiding mechanical failures caused by lubrication failure.
[0031] When using this towed desert concrete placing machine, a comprehensive inspection of the equipment is required first. Check that the protective cover 12 is securely installed, that the first gear 9, reduction motor 10, and second gear 11 are inside the protective cover 12 without obstruction, that the observation window 15 is clear and undamaged, that the lifting ring 14 is securely connected, that the cover plate 13 opens and closes smoothly, that the traction frame 16 is free from deformation, that the surface of the guide ramp 17 is smooth, and that the bearings and sealing shaft covers are intact. After inspection, move the equipment to a suitable working position using the lifting ring 14, and then securely connect the traction frame 16 to the towing equipment. Next, open the cover plate 13 and add water-retaining sand to the storage bin 1 through the feeding port. During the adding process, observe the amount of water-retaining sand through the observation window 15 to avoid overfilling. After adding, close the cover plate 13. Then the reduction motor 10 is started, which drives the second gear 11 to rotate. The second gear 11 drives the first gear 9 that meshes with it to rotate. Since the adjacent first gears 9 mesh with each other, all the first gears 9 rotate synchronously and drive the screw conveyor rod 8 to rotate. At this time, the traction equipment drives the concrete placing machine to move in the desert through the rollers 4. The traction equipment moves at a speed of 0.5-1.2 km / h. The water-retaining sand in the storage bin 1 flows to the hollow metal triangular plowshare 5 under the guidance of the guide slope plate 17. The screw conveyor 8 pushes the water-retaining sand into the hollow metal triangular plowshare 5. As the equipment moves forward, the hollow metal triangular plowshare 5 cuts through the sand layer, and the water-retaining sand flows out from the placing hole 6 and is laid on the ground. A 4000mm wide horizontal overlap can be formed into a 15mm thick water-retaining sand layer in one go, which ensures the width and thickness of the water-retaining sand laying, improves the water retention effect, and greatly improves the laying efficiency. Compared with the traditional manual laying method, it can save a lot of manpower and time costs and can meet the needs of large-scale desert control projects.
