Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, and particularly relates to a concrete batching machine. Background Art

[0002] Concrete is a widely used building material. It is an artificial building material mixed by cement, sand, aggregate and water, and has advantages such as high strength, durability and fire resistance. A concrete batching machine is a front-end automatic batching device used in conjunction with a mixer, and has advantages such as high metering accuracy, high distribution efficiency and high automation degree. It is one of the main parts of a complete set of fully automatic concrete mixing plant equipment.

[0003] When using the batching machine to carry out the proportioning work of concrete raw materials, due to factors such as the mining restriction of natural sand and the wide use of artificial manufactured sand, the water content of the sand and gravel used in concrete is relatively high. When the sand and gravel with a high water content fall onto the conveyor belt of the batching machine, some of the sand and gravel will adhere to the conveyor belt. The above situation will cause the phenomenon that the sand and gravel first adhere to the conveyor belt and then fall off the belt after passing over the lower hopper, which will require the staff to collect and clean up the fallen sand and gravel subsequently, increasing the labor cost.

[0025] The present utility model provides a concrete batching machine as Figures 1-4 shown, which includes a batching machine body 1. The batching machine body 1 is composed of an outer frame 101, two upper batching hoppers 102, two conveyor belts 103, a lower batching hopper 104 and four baffle plates 105. Scraping mechanisms 2 are provided below both of the two conveyor belts 103. The scraping mechanisms 2 are used to scrape the sand and gravel adsorbed on the belts of the conveyor belts 103. A locking mechanism 3 is provided between the two scraping mechanisms 2. The locking mechanism 3 plays a role in positioning the scraping mechanisms 2;

[0026] The scraping mechanism 2 includes a rotating rod 201. A strip-shaped rotating plate 202 is sleeved on the outer wall of the rotating rod 201. The strip-shaped rotating plate 202 is fixedly sleeved on the outer wall of the rotating rod 201. A scraping strip 203 is arranged on the top of the strip-shaped rotating plate 202. A rubber strip 204 is arranged between the scraping strip 203 and the strip-shaped rotating plate 202. The rubber strip 204 functions to buffer and protect the scraping strip 203. The rubber strip 204 is fixedly connected between the scraping strip 203 and the strip-shaped rotating plate 202. One end of the rotating rod 201 is provided with a rotating block 205. One end of the rotating rod 201 penetrates through the back surface of the corresponding baffle 105 and is fixedly connected to the back surface of the rotating block 205. A circular hole is opened on the front surface of the baffle 105. The outer wall of the rotating rod 201 is rotationally connected to the inner cavity of the circular hole. One side of the rotating block 205 is fixedly connected with an auxiliary rod 206. The auxiliary rod 206 is used to facilitate the staff to apply force to drive the rotation of the rotating block 205 and the rotating rod 201. The outer wall of the auxiliary rod 206 is provided with uniformly distributed anti-slip lines, and the anti-slip lines are used to increase the friction between the auxiliary rod 206 and the palm of the staff.

[0027] The locking mechanism 3 is composed of a T-shaped plate 301, a pressing plate 302, an adjusting bolt 303, two locking rods 304 and two anti-slip blocks 305. A driving cavity is opened in the inner cavity of the T-shaped plate 301. The pressing plate 302 is located inside the driving cavity. A limiting slide hole is opened at the bottom of the pressing plate 302. A limiting slide rod 306 is arranged in the inner cavity of the limiting slide hole. The limiting slide hole and the limiting slide rod 306 are used to ensure that the pressing plate 302 can move smoothly in the vertical direction. The bottom end of the limiting slide rod 306 is fixedly connected to the bottom of the inner wall of the driving cavity. A threaded hole is opened at the top of the inner wall of the driving cavity. The inner wall of the threaded hole is threadedly connected to the outer wall of the adjusting bolt 303. The bottom end of the adjusting bolt 303 is rotationally connected to the top of the pressing plate 302. A cross bar can be installed at the large head end of the adjusting bolt 303 to assist the staff to apply force to drive the rotation of the adjusting bolt 303. Telescopic holes are symmetrically opened on both sides of the inner wall of the driving cavity. The outer walls of the two locking rods 304 are movably sleeved in the inner cavities of the corresponding telescopic holes. A roller groove is opened at one end of the locking rod 304. A force-bearing roller 308 is rotationally connected in the inner cavity of the roller groove. The force-bearing roller 308 is used to improve the smoothness of the pressing plate 302 driving the locking rod 304 to move. Strip-shaped slide holes are opened at the tops of the two locking rods 304. The outer walls of the two anti-slip blocks 305 are slidably sleeved in the inner cavities of the corresponding strip-shaped slide holes. The strip-shaped slide holes and the anti-slip blocks 305 are used to prevent the locking rods 304 from detaching from the telescopic holes. The two anti-slip blocks 305 are fixedly connected to the inner cavities of the corresponding telescopic holes. One side of the anti-slip block 305 is fixedly connected with a return spring 307. The return spring 307 can undergo elastic deformation to drive the locking rod 304 to automatically perform a reset movement, improving the convenience of operation. One end of the return spring 307 is fixedly connected to one side of the inner wall of the strip-shaped slide hole.

[0028] The working principle of the present utility model:

[0029] When the water content of sand and gravel in the concrete batching machine is relatively high and adheres to the belt of the conveyor belt 103, first apply a turning force to the auxiliary rod 206, so that the auxiliary rod 206 drives the strip-shaped rotating plate 202 to rotate towards the corresponding conveyor belt 103 through the rotating block 205 and the rotating rod 201. When the side of the scraping strip 203 contacts the outer surface of the belt of the conveyor belt 103, remove the turning force applied to the auxiliary rod 206. After operating both scraping mechanisms 2 according to the above steps, apply a clockwise turning force to the adjusting bolt 303. The adjusting bolt 303 will drive the pressing plate 302 to move vertically downward. During the vertical downward movement of the pressing plate 302, the two inclined surfaces of the pressing plate 302 will apply a pressing force to the two force-bearing rollers 308, so that the two locking rods 304 move away from each other. When both locking rods 304 move to the top of the rotating block 205, stop rotating the adjusting bolt 303. At this time, the positioning of the scraping strip 203 is completed, effectively scraping the sand and gravel adsorbed on the conveyor belt 103, avoiding the phenomenon that the sand and gravel first adhere to the belt of the conveyor belt 103 and then fall from the belt after passing over the lower batching hopper 104, and eliminating the need for staff to collect and clean up the fallen sand and gravel later, reducing labor costs.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
