Description

Technical Field

[0001] This utility model relates to the field of road repair technology, and in particular to a road cement sand mixing device. Background Technology

[0002] When road surfaces are damaged, concrete is needed for repair. Concrete is also known as cement. To ensure the stability of cement when used as a road repair material, sand and gravel are usually added to it. Because cement shrinks during hydration and hardening, pure cement paste is prone to cracking due to internal stress. The added sand acts as aggregate to fill the gaps, which can disperse shrinkage stress and significantly reduce the risk of cracking. Therefore, in small-area road repair work, the method of adding sand to cement and then mixing it manually is a common way to prepare concrete.

[0003] In the existing cement sand-addition process, manual labor is mainly used to transport and add sand and gravel materials using wheelbarrows. After the sand and gravel are transported to the cement mixing area, they are poured out and gradually added to the cement material using tools such as shovels for mixing. Then, qualified concrete is formed for road surface repair work.

[0004] In the aforementioned road repair work, the cement sand-addition process mainly involves workers operating wheelbarrows and using shovels to add sand and gravel. However, because sand and gravel are added to cement mixing materials such as lime using shovels, the addition process is not uniform, and the sand and gravel are added in a concentrated manner, resulting in low mixing efficiency in the later stages and affecting cement setting time and road repair efficiency.

[0005] The purpose of this utility model is to provide a road cement sand-adding device to solve the technical problems mentioned in the background art. To achieve the above objectives, the present invention adopts the following technical solution: A road cement sand-adding device includes a main body with a sand-discharging disc mounted on its bottom. The sand-discharging disc includes a disc frame, and a base plate frame is fixed to the bottom of the disc frame. A sand-discharging pipe is fixed to one side of the bottom of the base plate frame, and a butterfly valve is fixed inside the sand-discharging pipe. Bearing rings are embedded around the outer wall of the disc frame, and a linkage ring is fixed in a ring around the bottom of the base plate frame. The outer wall of the linkage ring has a toothed groove, and a gear is fitted to the outer wall of the toothed groove. A drive motor is connected to the central shaft at the top of the gear, and a power module is fixed to one side of the drive motor.

[0006] Furthermore, the tray frame forms a rotating structure with the main body of the equipment through a bearing ring, and the base plate frame is fixedly connected to the bottom end of the tray frame.

[0007] Furthermore, the bottom surface of the base plate frame is eccentrically conical along one side, and the bottom surface of the base plate frame is connected to the sand discharge pipe.

[0008] Furthermore, the drive motor is fixedly connected to the outer wall of one side of the main body of the equipment, and the power module is electrically connected to the drive motor.

[0009] Furthermore, the linkage ring is driven by meshing with a gear through a tooth groove, and the gear forms a rotating structure with the main body of the equipment through a drive motor.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0016] like Figure 1-4 As shown, a road cement sand adding equipment includes a main body 1, a sand discharge disc 2 mounted on the bottom of the main body 1, an outer frame 101, a material storage chamber 102 opened inside the outer frame 101, a handle 103 fixed on one side of the outer wall of the outer frame 101, support rods 104 fixed around the bottom of the outer frame 101, a bottom connecting frame 105 fixed between the support rods 104, and casters 106 fixed at the bottom of the support rods 104. To provide this road cement mixing equipment with temporary storage and convenient transportation capabilities for sand and gravel aggregates, such as Figure 1 As shown, this road cement sand-adding equipment provides storage space for sand and gravel aggregates through the outer frame 101 and the internal storage chamber 102. The multiple sets of support rods 104, which are fixed in a ring at the bottom of the outer frame 101, are fixed to the bottom connecting frame 105 to maintain the stability of the bottom structure. At the same time, the universal wheels 106 can facilitate the movement of the entire equipment structure. The handle 103 makes it convenient for construction personnel to carry and move the aggregates, and facilitates the sand-adding of cement materials for roads.

[0017] like Figure 2-4 As shown, the sand discharge disc 2 includes a disc frame 201, and a base plate frame 202 is fixed to the bottom end of the disc frame 201. A sand discharge pipe 203 is fixed to one side of the bottom end of the base plate frame 202, and a butterfly valve 204 is fixed inside the sand discharge pipe 203. A bearing ring 205 is embedded around the outer wall of the disc frame 201, and a linkage ring 206 is fixed around the bottom end of the base plate frame 202. A toothed groove 207 is opened on the outer wall of the linkage ring 206, and a gear 208 is attached to the outer wall of the toothed groove 207. A drive motor 209 is connected to the central shaft at the top of the gear 208, and a power module 210 is fixed to one side of the drive motor 209. To facilitate the uniform addition of aggregates to cement using this sand-adding equipment, such as... Figure 2-4As shown, this road cement sand adding equipment forms a storage chamber 102 inside the outer frame 101 with the disc frame 201 to store sand and gravel aggregate. During the sand adding process, the equipment can be positioned on top of the cement material being added. The drive motor 209 drives the meshing linkage ring 206 and the disc frame 201, causing the disc frame 201 to rotate along the inner wall of the outer frame 101. Meanwhile, the bottom plate frame 202, with its conical structure, can work with the sand discharge pipe 203 to evenly sprinkle the cement material in a ring shape. This ensures the uniformity of the material after transportation and input into the sand adding process, improves cement quality, reduces the frequency of subsequent mixing, and improves the overall efficiency of road repair operations. The butterfly valve 204 installed on the aforementioned sand discharge pipe 203 has a common valve body structure in the prior art. By rotating the annular handle on the outside of the butterfly valve 204, the butterfly disc inside the butterfly valve 204 rotates, thereby opening the internal opening of the sand discharge pipe 203 and allowing sand and gravel to be discharged from the sand discharge pipe 203. The process of discharging sand and gravel into the cement material below by rotating makes the sand and gravel more evenly sprinkled on the cement surface, reducing the time workers spend mixing the cement material afterward. This avoids the phenomenon in traditional operation where sand and gravel are dumped in one place in the cement material, increasing the workload of subsequent mixing.

[0018] In summary, when using this road cement sand mixing equipment, the user first stores and stores the sand and gravel aggregate in the storage chamber 102 formed by the inner frame 101 and the disc frame 201. After storing the material, the user can hold the handle frame 103 to move the outer frame 101. The support rod 104 and casters 106 at the bottom of the outer frame 101 move the equipment along the construction road surface until the bottom of the equipment is aligned with the road cement material to be mixed. During the movement, the equipment enters the cement area through the notch on the other side of the semi-circular bottom connecting frame 105, avoiding contact with the cement material below. Then, the power module 210... The wiring connection supplies power to the drive motor 209, which in turn drives the gear 208 to rotate. The rotating gear 208 then drives the meshing linkage ring 206 for synchronous transmission. The disc frame 201, which is fixed on the top surface of the linkage ring 206, rotates synchronously with the transmission, causing the disc frame 201 to rotate along the bearing ring 205 and the outer frame 101. During the rotation, the bottom butterfly valve 204 opens, and with the inverted conical structure of the bottom plate frame 202, the sand and gravel aggregate is discharged uniformly from the sand discharge pipe 203. At the same time, as the rotation occurs, it is evenly sprinkled into the bottom cement material in a ring. At this time, the construction personnel can stir the cement repair material to complete the sand addition process.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
