Abstract
Description
Technical Field
[0001] The present application relates to the field of sand making, and in particular to a material feeding device. Background Art
[0002] Artificial sand is made by crushing stones with sand making equipment. Different from sea sand, it has uniform particles and does not contain salt. It is widely used, especially in the construction industry. In concrete manufacturing, there are requirements for the coarseness ratio of sand. According to different ratios, it is divided into coarse sand, medium sand, fine sand, etc. The proportion of large particles in coarse sand is higher than that in medium sand, and the proportion of large particles in medium sand is higher than that in fine sand.
[0003] After the sand-making enterprise makes sand, downstream companies such as concrete companies need to prepare multiple silos. Different silos store sand of different particle sizes, and then mix and proportion them to get sand of different coarseness. This increases the working procedures of downstream companies, and the silos take up a lot of site space. Utility Model Content
[0004] In order to improve the problem of increased working procedures and the silo occupying a large amount of site space, the present application provides a material unloading device.
[0005] The present application provides a feeding device, which adopts the following technical solution:
[0006] A feeding device comprises a plurality of sand throwing devices and a feeding head, wherein the sand throwing devices are connected to the feeding port of the sand making equipment, and the plurality of sand throwing devices are used to feed sand into the feeding port of the feeding head, and a sand mixing component is arranged in the feeding head, and the sand mixing component is used to mix the sand and then discharge the sand from the feeding port of the feeding head.
[0007] By adopting the above technical scheme, the sand made by the sand making equipment is directly transported to the discharge head through the sand throwing device, and then mixed through the sand mixing component. The sand mixing component can directly and continuously mix a small amount of sand, thereby improving the mixing efficiency and facilitating the mixing. It eliminates the need for downstream enterprises to first store the sand made by the sand making equipment in different silos, and then mix the sand from different silos in a certain ratio to obtain the required coarseness of sand. Since the amount of sand taken by the downstream enterprises is large, it can only be mixed through special mixing equipment. In the upstream sand making enterprises, sand can be made and mixed at the same time, and the amount is small and continuous. The sand mixing component can be used for efficient mixing. The upstream sand making enterprises directly mix the produced sand in a certain ratio to obtain the sand required by the downstream enterprises, and then sell it to the downstream enterprises. The silos in the downstream enterprises are eliminated, thus reducing costs.
[0008] Optionally, a conveying mechanism is further provided between the sand throwing device and the feeding port of the material discharge head, and the plurality of sand throwing devices throw sand onto the conveying mechanism, and the conveying mechanism throws sand into the feeding port of the material discharge head.
[0009] By adopting the above technical solution, the sand of the sand-feeding device is carried by a conveying mechanism and then fed into a feeding head for mixing. The conveying mechanism also allows a greater number of sand-feeding devices to feed materials at the same time, thereby increasing the range of the mixing ratio.
[0010] Optionally, the conveying mechanism includes a conveyor belt, the feed inlet of the feed head is located below the end of the conveying direction of the conveyor belt, and the discharge outlets of the plurality of sand throwing devices are distributed on the conveyor belt.
[0011] By adopting the above technical solution, sand is thrown onto the conveyor belt through multiple sand throwing devices, and then the conveyor belt gradually transfers the material forward until it falls into the discharge head. The length of the conveyor belt can be adapted to multiple sand throwing devices at the same time, and the sand thrown by the sand throwing device is accumulated on the conveyor belt, so that the staff can directly and intuitively observe the approximate ratio of the sand.
[0012] Optionally, the discharge ports of the multiple sand throwing devices are distributed on both sides of the conveying direction of the conveyor belt, and the discharge ports of the multiple sand throwing devices are distributed along the conveying direction of the conveyor belt, and the discharge ports of the multiple sand throwing devices are staggered.
[0013] By adopting the above technical solution, the discharges of multiple sand-throwing devices are staggered and arranged at the same position of the conveyor belt, so that sand thrown in from different positions can be piled together, thereby improving the mixing efficiency.
[0014] Optionally, a concave inclined surface is formed on the conveyor belt, and adjacent concave inclined surfaces form a concave chute, and the discharge ports of the multiple sand-throwing devices throw sand into the concave chute, and the concave chute is used to centrally mix the sand on the conveyor belt.
[0015] By adopting the above technical solution, the input sand is gathered in the inner concave chute, so that it can be fed into the feeding head after mixing, thereby improving the mixing efficiency and making the mixing more uniform.
[0016] Optionally, the sand mixing assembly includes a mixing plate group, the mixing plate group includes a plurality of mixing plates arranged at an angle, and the plurality of mixing plates are also arranged in a staggered manner so that the mixing plate located above guides the sand to slide onto the mixing plate located below.
[0017] By adopting the above technical solution, the sand is guided to roll down through the mixing plate, and the impact of the sand on the mixing plate can better mix the sand, that is, after the sand falls, it is rebounded and bounced up to mix with the sand that has just fallen from above, so that the mixing is more uniform.
[0018] Optionally, there are multiple mixing plate groups, and the multiple mixing plate groups are distributed along the falling direction of the sand in the feeding head.
[0019] By adopting the above technical solution, multiple groups of mixing plates are used to mix the sand, thereby improving the mixing effect.
[0020] Optionally, a plurality of inclined bars are provided on the mixing board, and the side walls of the inclined bars that are in contact with the sand are inclined, and the inclined bars are used to lift the sand from the mixing board and then let the sand slide onto the mixing board.
[0021] By adopting the above technical solution, the sand is allowed to fall, impact and mix on the mixing plate through the inclined strips, thereby further improving the mixing efficiency.
[0022] Optionally, the inclined angle of the inclined side wall is smaller than the inclined angle of the mixing plate, and the inclined side wall is still inclined along the direction of gravity to guide the sand to roll downward.
[0023] By adopting the above technical solution, the inclined strips will not stop the sand. Only because the relative height of the inclined strips is higher than the mixing board, the sand is lifted up during the sliding process and then falls on the mixing board, thereby improving the mixing effect.
[0024] Optionally, a plurality of mixing strips are provided on the mixing plate, and the side walls of the mixing strips for contacting the sand are arranged at an inclination, and the inclined mixing strips are used to cut off the sand and guide it to the next mixing strip.
[0025] By adopting the above technical solution, the sand is dropped onto the mixing bar through the mixing bar, and then drops along the mixing bar to the next mixing bar, thereby improving the mixing efficiency.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. Sand is made and mixed at the same time, in small and continuous quantities. Efficient mixing can be carried out through sand mixing components. The upstream enterprises making sand directly mix the produced sand according to a certain ratio to obtain the sand required by the downstream enterprises, and then sell it to the downstream enterprises, eliminating the silos in the downstream enterprises and reducing costs.
[0028] 2. The sand is guided to roll down through the mixing plate, and the impact of the sand on the mixing plate can mix the sand better and more evenly. BRIEF DESCRIPTION OF THE DRAWINGS
