Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a concrete feeding device for concrete production. Background Technology

[0002] Ordinary concrete is an artificial stone material formed by mixing and hardening cement as a binder, coarse and fine aggregates as a skeleton, and admixtures and water as auxiliary components. Among them, sand and gravel aggregates mainly play a skeleton support role in concrete, and can effectively inhibit the shrinkage of cement paste. The cement paste formed by the reaction of cement and water coats the surface of aggregates and fills their voids, so that concrete forms a uniform and dense overall structure.

[0003] In the concrete production process, the hopper is a key conveying device used to transfer the mixed concrete to a designated location. However, in actual use, the discharge port at the bottom of the hopper often gets blocked, which seriously affects production efficiency. Especially under continuous operation conditions, frequent blockages can lead to production interruptions and significantly reduce the concrete discharge efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of clogging of the hopper affecting the material feeding efficiency in the prior art, and to propose a concrete feeding device for concrete production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete feeding device for concrete production includes a first housing and a second housing, which are connected to form a feeding cavity. A feed pipe is fixedly connected to the first housing. At least one set of elongated scrapers is rotatably connected to the outer wall of the feed pipe. The elongated scrapers are in contact with the inner wall of the first housing. A spiral scraper is provided at the bottom of the elongated scraper. The side wall of the spiral scraper extends to form a tip, which is in contact with the inner wall of the second housing. A driving part is provided on the first housing for driving the spiral scraper to move in contact with the inner wall of the second housing.

[0007] To facilitate the rotation of the long scraper, preferably, the drive unit includes a rotating shaft rotatably connected to the first housing, a main gear rotatably connected to the outer wall of the feed pipe, an auxiliary gear fixedly connected to the bottom of the rotating shaft, the main gear meshing with the auxiliary gear, and the long scraper fixedly connected to the main gear.

[0008] To facilitate the connection and positioning of the main gear, at least one set of limiting plates is fixedly connected to the outer wall of the feed pipe. The main gear is rotatably connected to the limiting plates. The limiting plates are provided with sliding grooves, and the main gear is provided with connecting grooves. A sliding channel is formed between the sliding grooves and the connecting grooves, and ball bearings are provided in the sliding channel.

[0009] Furthermore, a partition is fixedly connected to the outer wall of the feed pipe. The partition is located below the main gear, and a transmission channel is formed between the partition and the inner wall of the first housing. A long scraper is located in the transmission channel.

[0010] To facilitate the rotation of the shaft, a motor is further fixedly connected to the top of the first housing, and the shaft is fixedly connected to the output end of the motor.

[0011] To improve the service life of the tip, preferably, the surface of the tip is coated with a polyurethane layer or a tungsten carbide layer.

[0012] Compared with the prior art, this utility model provides a concrete feeding device for concrete production, which has the following beneficial effects:

[0013] 1. The concrete feeding device for concrete production uses a combination of long scraper and spiral scraper to achieve a scraping effect. The long scraper treats the vertical surface on the first shell, and the spiral scraper treats the conical surface on the inner wall of the second shell, so as to realize the real-time cleaning of the inner wall concrete and keep the flow channel unobstructed.

[0014] 2. This concrete feeding device for concrete production can actively break up the initial set concrete layer on the inner wall of the second shell by rotating the spiral scraper. At the same time, it performs a spiral propulsion motion to guide the concrete to be quickly transported to the discharge port of the second shell, preventing the discharge port from sticky blockage. It is particularly suitable for high-intensity continuous operation scenarios such as commercial concrete plants.

[0015] 3. The concrete feeding device for concrete production can form a closed flow channel by directly connecting the feed pipe to the production equipment, avoiding material spillage during transfer and improving the feeding speed.

[0016] The parts not covered in this device are the same as or can be implemented using existing technologies. This utility model can actively break the initial set concrete layer on the inner wall of the two sets of shells, and at the same time make a spiral propulsion motion to guide the concrete to be quickly transported to the discharge port of the second shell, preventing the discharge port from having adhesive blockage problems. It is particularly suitable for high-intensity continuous operation scenarios such as commercial concrete plants. Attached Figure Description

[0024] Example:

[0025] Reference Figures 1-4A concrete feeding device for concrete production includes a first housing 1 and a second housing 2, which are connected to form a feeding cavity. A rubber ring is installed at the bottom of the second housing 2 to flexibly block the concrete and ensure its stability during feeding. A feed pipe 3 is fixedly connected to the first housing 1 to connect to the output end of a concrete production machine, allowing concrete to enter the feed pipe 3, be transported through the feed pipe 3 into the feeding cavity, and then output from the bottom of the second housing 2, thus achieving the concrete feeding effect. A series of rotating parts are rotatably connected to the outer wall of the feed pipe 3. The device has three sets of long scraper blades 9 arranged equidistantly in a circle. The long scraper blades 9 are attached to the inner wall of the first housing 1, so as to scrape off the concrete on the inner wall of the first housing 1 and achieve the effect of continuous adhesion of subsequent concrete. A spiral scraper blade 10 is provided at the bottom of the long scraper blades 9. The side wall surface of the spiral scraper blade 10 extends to form a tip. In order to improve the service life of the tip, a polyurethane layer or tungsten carbide layer is sprayed on the surface of the tip. The tip is then attached to the inner wall of the second housing 2. A driving part is provided on the first housing 1 to drive the spiral scraper blade 10 to move and adhere to the inner wall of the second housing 2.

[0026] In the above scheme, the long scraper 9 and the spiral scraper 10 work together to form a scraping effect. The long scraper 9 treats the vertical surface on the first shell 1, and the spiral scraper 10 treats the conical surface on the inner wall of the second shell 2, realizing real-time cleaning of the inner wall concrete, keeping the flow channel unobstructed. When the spiral scraper 10 rotates, it can actively break up the initial set concrete layer on the inner wall of the second shell 2. At the same time, the spiral scraper 10 performs a spiral propulsion motion during rotation, guiding the concrete to be quickly transported to the discharge port of the second shell 2, preventing the discharge port from sticking and clogging. It is particularly suitable for high-intensity continuous operation scenarios such as commercial concrete plants. Furthermore, the design of the feed pipe 3 being directly connected to the production equipment can form a closed flow channel, avoiding material spillage during transfer and improving the feeding speed.

[0027] The aforementioned drive unit includes a rotating shaft 13 rotatably connected to the first housing 1, a main gear 6 rotatably connected to the outer wall of the feed pipe 3, an auxiliary gear 14 fixedly connected to the bottom of the rotating shaft 13, the main gear 6 meshing with the auxiliary gear 14, a long scraper 9 fixedly connected to the main gear 6, a motor 12 fixedly connected to the top of the first housing 1, and the rotating shaft 13 fixedly connected to the output end of the motor 12. The main gear 6 serves as the drive input end, obtaining rotational power through the motor 12, driving the rotating shaft 13 to rotate, causing the auxiliary gear 14 to drive the main gear 6 to rotate, thereby causing the main gear 6 to drive the long scraper 9 to rotate circumferentially.

[0028] At least one set of limiting plates 4 are fixedly connected to the outer wall of the feed pipe 3. The device is provided with two sets of symmetrical limiting plates 4 for connecting the main gear 6. The limiting plate 4 is provided with a sliding groove 5, and the main gear 6 is provided with a connecting groove 7. A sliding channel is formed between the sliding groove 5 and the connecting groove 7. A ball bearing 8 is provided in the sliding channel. The ball bearing 8 rolls in the sliding channel formed by the sliding groove 5 and the connecting groove 7. Lubricant is filled in the sliding channel to improve the connection effect of the ball bearing 8, thereby making the main gear 6 rotate on the limiting plate 4.

[0029] It should be explained that the outlet of the feed pipe 3 is located inside the cavity of the first housing 1. A partition 11 is fixedly connected to the outer wall of the feed pipe 3. The partition 11 is located below the main gear 6. A transmission channel is formed between the partition 11 and the inner wall of the first housing 1. The long scraper 9 is located inside the transmission channel. The partition 11 can prevent the concrete during the feeding process from affecting the main gear 6.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
