Abstract
Description
Technical Field
[0001] The utility model relates to the technology of filling solid particles in deep holes. Background Art
[0002] The railway subgrade is exposed to the atmosphere, and the atmospheric environment has an important impact on the railway subgrade. Especially in the vast northwest region of China, due to the relatively low winter temperature, the phenomenon of frost heaving of the railway subgrade in winter occurs, which has a greater impact on railway operation. At the same time, due to the gradual increase in precipitation in the northwest region of China in recent years, it has also played a certain role in promoting this frost heaving phenomenon.
[0003] At present, for preventing frost heaving of the railway subgrade, the methods of subgrade drainage and heat preservation are mostly adopted to reduce the possibility of frost heaving of the railway subgrade, and certain effects have been achieved. However, due to the gradual increase and persistence of precipitation, this repeated drainage method will consume a large amount of funds and time. Another method is to inject salt into the subgrade to lower the freezing point of the subgrade, so that the freezing point of the subgrade soil drops below the lowest temperature of the subgrade to avoid the subgrade from freezing. However, generally when injecting salt into the subgrade, the salt needs to be dissolved in water first, which leads to more water remaining in the subgrade after injecting salt, and the problem of subgrade drainage appears again. If holes can be drilled in the subgrade first and then solid salt can be directly poured into the holes, this problem can be better solved. However, at present, there is no effective solid particle filling device. If the method of directly drilling holes in the soil and then pouring solid salt into the holes is adopted, unless the inclination of the hole is large, it is not only difficult to pour the solid salt to the bottom of the hole, but also difficult to ensure the compactness of the salt. Therefore, a solid particle filling device is urgently needed at present. Summary of the Invention
[0004] The purpose of the utility model is to fill solid particle salt into holes with a relatively small cross-section and a relatively deep depth to lower the freezing point of the railway subgrade and prevent the railway subgrade from frost heaving.
[0005] The utility model is a solid particle filling device, which includes a feeding funnel 1, a feeding box 2, and a filling cylinder 3. The feeding funnel 1 includes an opening part 1-1 and a tail part 1-2. The opening part 1-1 is a section of reducing pipe, and the tail part 1-2 is a section of circular pipe. The small end of the reducing pipe is connected to the circular pipe, and the large end faces outward. The feeding box 2 is composed of a housing 2-1, a rotating wheel 2-2, and blades 2-3. The filling cylinder 3 is composed of a variable cross-section section 3-1 and an equal cross-section section 3-2. The feeding funnel 1 and the feeding box 2 are connected by a connection port 4. A rotating rocker 6, a support leg 7, and a handle 8 are arranged outside the feeding box 2.
[0006] The beneficial effects of the present utility model are as follows: The filling device can fill solid particulate matter into deep holes and can compact the solid particulate matter, meeting the filling requirements for solid particulate matter under special engineering conditions, which is of great significance. The structural form of the present utility model is relatively simple, with strong practicability and remarkable economic benefits. Description of the Drawings

Detailed Embodiment
[0008] As Figure 1 , Figure 2 , Figure 5 shown, the present utility model is a filling device for solid particulate matter, including a feeding funnel 1, a feeding box 2, and a filling cylinder 3. The feeding funnel 1 includes an opening part 1-1 and a tail part 1-2. The opening part 1-1 is a section of stepped pipe, and the tail part 1-2 is a section of round pipe. The small end of the stepped pipe is connected to the round pipe, and the large end faces outward to facilitate the entry of solid particulate matter. The feeding box 2 is composed of a housing 2-1, a rotating wheel 2-2, and blades 2-3. The filling cylinder 3 is composed of a variable cross-section section 3-1 and an equal cross-section section 3-2. The feeding funnel 1 and the feeding box 2 are connected by a connection port 4, and the end of the connection port is covered with a lid 5. A rotating rocker 6, legs 7, and a handle 8 are provided on the outside of the feeding box 2.
[0009] As Figure 2 shown, the housing 2-1 of the feeding box 2 is disc-shaped. Inside the housing 2-1 are the rotating wheel 2-2 and the blades 2-3. The blades 2-3 are fixed on the rotating wheel 2-2 and can rotate together with the rotating wheel 2-2. The shape of the blades 2-3 adopts the form of involute to ensure that as many solid particulate matters as possible can be pushed into the filling cylinder 3 during the rotation process, rather than making the solid particulate matters circulate in the feeding box 2 along with the rotation of the blades 2-3. Three connection ports 4 are provided at the top, tail, and the middle part between the top and the tail of the feeding box 2 to ensure that when the filling cylinder 3 performs filling operations at different angles with the horizontal line, the outer opening of the feeding funnel 1 faces upward to facilitate the smooth entry of solid particulate matter into the feeding box 2.
[0010] As Figure 3As shown, the connection port 4 is cylindrical. One end of the connection port 4 is fixedly connected to the outer shell 2-1 of the feeding box, and the other end is covered by a lid 5. The lid 5 is opened when it is necessary to connect with the feeding funnel 1. The inner diameter of the cylinder of the connection port 4 is 0.5 mm larger than the outer diameter of the tail circular tube of the feeding funnel 1, so as to ensure that the tail circular tube 1-2 of the feeding funnel 1 can be inserted into the cylinder of the connection port 4 and the connection between the two is relatively tight; the length of the cylinder of the connection port 4 is 5 mm longer than the length of the circular tube of the feeding funnel 1, so as to ensure that the tail circular tube 1-2 of the feeding hopper does not extend into the feeding box 2.
[0011] As Figure 2 , Figure 3 shown, a section of the packing cylinder 3 close to the feeding box 2 is a variable cross-section section 3-1, and the cross-section becomes larger as it gets closer to the feeding box, which ensures that the solid particulate matter is pressed more tightly the farther it is from the feeding box 2; the equal cross-section section 3-2 ensures that the packing can smoothly advance towards the end of the packing cylinder 3; the inner wall of the packing cylinder 3 is set very smooth to reduce the friction between the inner wall of the packing cylinder 3 and the solid particulate matter when the solid particulate matter advances towards the end of the packing cylinder 3.
[0012] As Figure 1 , Figures 4 to 6 shown, a rotating rocker 6 is provided on one side of the feeding box 2. The rotating rocker 6 includes a transmission shaft 6-1, a force transmission rod 6-2, a handle 6-3, a pressure ring 6-4, and a pressure display screen 6-5. The transmission shaft 6-1 is fixedly connected to the rotating wheel 2-2; rotating the handle 6-3 can drive the transmission shaft 6-1 to rotate through the force transmission rod 6-2, and then drive the rotating wheel 2-2 to rotate; a pressure ring 6-4 is provided between the handle 6-3 and the force transmission rod 6-2, which can measure the force used when rotating the handle 6-3 and display it on the pressure display screen 6-5 at the end of the force transmission rod 6-2, so as to determine the compaction degree of the solid particulate matter in the packing cylinder 3.
[0013] As Figures 4 to 6 shown, legs 7 are provided at the bottom of the feeding box 2 to support the gravity of the entire device and provide a stable support for the device during operation; as the solid particulate matter in the deep hole is gradually filled from the hole bottom outwards, the support also needs to move backward continuously. A handle 8 is provided on the other side of the feeding box 2 opposite to the rotating rocker 6, which is mainly used to stabilize the entire device during operation to achieve a good working effect.
