Description

Technical Field

[0001] The invention relates to the technical field of discharging equipment, and in particular to a concrete material discharging device. Background Art

[0002] In the concrete manufacturing process, materials such as cement, sand and gravel are needed. The discharge methods of these materials are mostly as follows: the materials are moved onto the conveyor belt through the dock, dropped into the bottom of the conical silo through the conveyor belt, discharged vertically to the induction scale through the rod valve, and then dropped into the conveyor belt to enter the material mixer.

[0003] The existing material discharging method, although an induction scale is added to the discharging equipment, when the expected setting is reached, it usually takes several seconds for the induction scale to give feedback and stop unloading. Therefore, the discharge volume of the existing equipment will generally be tens to hundreds of pounds more than the expected value, which exceeds the error value control range. This makes the originally set good mix ratio fluctuate greatly, resulting in different strengths of concrete in the same batch, and even worse, it fails to reach the expected strength. This is a very dangerous thing in construction projects. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a concrete material discharging device, which can control the amount error of the discharged material within a range set by the error value.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A concrete material discharging device comprises: a loading and discharging device with a quantitative function, a quantitative cylinder used for cooperating with the loading and discharging device to load and discharge materials, and a material conveying belt arranged below the quantitative cylinder.

[0007] Preferably, the loading and discharging device includes a loading and discharging motor, a control frame installed on the loading and discharging motor, a quantitative controller installed on the control frame, and a quantitative device installed on the quantitative controller.

[0008] Preferably, the quantitative controller comprises a quantitative motor and bevel gears mounted on the quantitative motor.

[0009] Preferably, the quantitative device includes a quantitative controller 1 and a quantitative controller 2 movably connected to the quantitative controller 1.

[0010] Preferably, the quantitative controller includes a bevel tooth, a ring matched with the bevel tooth, a quantitative plate installed between the ring and the bevel tooth, and a scraper installed on the quantitative plate.

[0011] Preferably, the quantitative controller 2 includes a bevel gear 2, a fixed shaft installed on the bevel gear 2, a quantitative plate 2 installed on the fixed shaft, and a scraper 2 installed on the quantitative plate 2; the quantitative controller 2 is inserted into the bevel gear 1 and the ring through the fixed shaft and is movably connected to the quantitative controller 1.

[0012] Preferably, the quantitative controller is connected to the bevel gear 1 and the bevel gear 2 by means of bevel gears in an upper and lower meshing manner.

[0013] Preferably, the metering cylinder comprises a material barrel, the upper end of the material barrel is provided with a loading port, and the lower end of the material barrel is provided with a discharging port; the discharging port faces the material conveying belt below.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] The present invention adopts a loading and discharging device with a quantitative function, which can control the material within an error range; specifically, the quantitative device rotates under the action of the quantitative controller through the quantitative controller 1 and the quantitative controller 2, so that the quantitative plate 1 and the quantitative plate 2 are opened and closed to form sector areas s of different sizes, and the volume of the corresponding quantitative plate 1 and the quantitative plate 2 in the open and closed state is obtained according to the quantitative barrel height h, and then according to the volume formula V=s*h, the mass of the material is obtained according to m=ρ*v, that is, the amount of material required can be obtained by adjusting the opening and closing area of ​​the corresponding quantitative plate 1 and the quantitative plate 2. The material filling the quantitative device may exceed the quantitative plate 1 and the quantitative plate 2, but in the process of the quantitative device being transported to the discharge port, it will be scraped flat by the scraper 1 and the scraper 2 and the barrel cover. At this time, the material in the quantitative device is the set material weight. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0029] Embodiment 1:

[0030] A concrete material discharging device comprises: a loading and discharging device 10 with a quantitative function, a quantitative cylinder 20 for cooperating with the loading and discharging device 10 for loading and discharging, and a material conveying belt 30 arranged below the quantitative cylinder 20.

[0031] like Figure 1 As shown, in order to avoid the existing weighing equipment reaching the set value and the material still falling, resulting in the material amount exceeding the set value when discharging, not only causing waste of material, but also making the concrete strength unable to reach the expected value; therefore, this embodiment adopts a loading and discharging device 10 with a quantitative function. When the material is put into the loading and discharging device 10, it is always guaranteed to be the same batch during the process of being transported from the quantitative cylinder 20 to the material conveyor belt 30. The material amount in the discharging device 10 is controlled within the error range each time, thereby ensuring the mix ratio of concrete, improving the quality of the finished concrete product, and ensuring the safety of the project.

[0032] Furthermore, the loading and discharging device 10 includes a loading and discharging motor 11 , a control frame 12 mounted on the loading and discharging motor 11 , a quantitative controller 13 mounted on the control frame 12 , and a quantitative device 14 mounted on the quantitative controller 13 .

[0033] like Figure 2 As shown, the loading and discharging device 10 is installed in the quantitative cylinder 20. Only with the cooperation of the quantitative cylinder 20 can accurate quantitative measurement be achieved. Specifically, the loading and discharging device 10 controls the amount of material that can be loaded in the quantitative device 14 through the quantitative controller 13. Of course, when the quantitative device 14 is full, the feeding device may still be in operation. It takes several seconds of reaction time to stop the operation, which causes the amount in the quantitative device 14 to exceed the set value. However, this is only a loading process. Filling the quantitative device 14 with material is only to ensure that the quantitative device 1 4, when the loading and discharging motor 11 is started, the quantitative device 14 filled with materials will rotate in the quantitative cylinder 20. When the materials higher than the quantitative device 14 hit the cylinder cover of the quantitative cylinder 20, they will be scraped off by the cylinder cover. Some of the scraped materials will fall outside the cylinder, and some will fall to the bottom of the cylinder. They can be recovered by setting a collection frame in the concrete material discharging device. After the materials are scraped off, the materials left in the quantitative device 14 are the set material amount, and then they are sent to the material conveyor belt 30. This cycle is repeated, and the material discharge amount can be accurately controlled.

[0034] Furthermore, the quantitative controller 13 includes a quantitative motor 131 and a bevel gear 132 mounted on the quantitative motor 131 .

[0035] like Figure 3 As shown, the motor shaft of the quantitative motor 131 is installed with an umbrella gear 132. By rotating the quantitative motor 131, the umbrella gear 132 can be controlled to rotate clockwise or counterclockwise.

[0036] Furthermore, the quantitative device 14 includes a quantitative controller 1 141 and a quantitative controller 2 142 movably connected to the quantitative controller 1 141 .

[0037] Furthermore, the quantitative controller 141 includes a bevel tooth 1411, a ring 1412 paired with the bevel tooth 1411, a quantitative plate 1413 installed between the ring 1412 and the bevel tooth 1411, and a scraper 1414 installed on the quantitative plate 1413.

[0038] Furthermore, the quantitative controller 142 includes a second bevel gear 1421, a fixed shaft 1422 installed on the second bevel gear 1421, a quantitative plate 1423 installed on the fixed shaft 1422, and a scraper 1424 installed on the second quantitative plate 1423; the quantitative controller 142 is inserted into the bevel gear 1411 and the ring 1412 through the fixed shaft 1422 and is movably connected to the quantitative controller 141.

[0039] Furthermore, the quantitative controller 13 is meshed with the bevel tooth 1 1411 and the bevel tooth 2 1421 through the bevel tooth 132 .

[0040] like Figures 2 to 5 As shown, the scraper 1 1414 and the scraper 2 1424 are both groove-shaped, and are respectively installed on the edges of the quantitative plate 1 1413 and the quantitative plate 2 1423, and are in contact with the inner wall, the cylinder cover and the cylinder bottom of the quantitative cylinder 20. During the rotation of the quantitative device 14, the materials adhering to the inner wall, the cylinder cover and the cylinder bottom of the quantitative cylinder 20 can be cleaned to ensure the accuracy of the next material delivery amount, and at the same time have a cleaning effect.

[0041] The quantitative controller 13 is meshed with the bevel tooth 1411 and the bevel tooth 2 1421 at the same time through the bevel tooth 132. When the bevel tooth 132 rotates, the rotation directions of the bevel tooth 1411 and the bevel tooth 2 1421 are necessarily opposite, that is, when the bevel tooth 1411 rotates clockwise, the bevel tooth 2 1421 is necessarily counterclockwise. The quantitative controller 2 142 is inserted into the bevel tooth 1 1411 and the ring 1412 through the fixed shaft 1422 and is movably connected with the quantitative controller 1 141. When the fixed shaft 1422 is inserted into the bevel tooth 1 1411 and the ring 1412, the quantitative plate 1 1413 is first installed between the bevel tooth 1 1411 and the ring 1412, and then the quantitative plate 2 1423 is installed on the fixed shaft 1422.

[0042] In this way, when the bevel tooth 132 drives the bevel tooth 1411 and the bevel tooth 1421 to rotate, the quantitative plate 1413 and the quantitative plate 1423 can be expanded or closed with each other, thereby controlling the size of the fan-shaped area formed between the quantitative plate 1413 and the quantitative plate 1423. The quantitative plate 1 1413, the quantitative plate 1423 and the quantitative cylinder 20 have the same height of space. At this time, the volume of the corresponding quantitative plate 1 1413 and the quantitative plate 2 1423 in the open and closed state can be obtained according to the volume formula V=s*h, and then the weight of the material in this state can be obtained according to m=ρ*v.

[0043] Furthermore, the metering cylinder 20 includes a barrel 21 , a loading port 22 is provided at the upper end of the barrel 21 , and a discharge port 23 is provided at the lower end; the discharge port 23 faces the material conveying belt 30 below.

[0044] like Figures 1 to 8 As shown, the working principle of the present invention is as follows: according to the mix ratio under the concrete strength, the discharge amount of all materials each time is calculated, and then the quantitative motor 131 is started. Through the connection relationship, the quantitative plate 1 1413 and the quantitative plate 2 1423 can be rotated, and the required opening and closing fan-shaped areas of the quantitative plate 1 1413 and the quantitative plate 2 142 are adjusted. Then, the quantitative device 14 is driven to rotate through the control frame 12 by the loading and unloading motor 11, and the quantitative device 14 is rotated to the center position of the discharge port 23 of the barrel 21. Then, the feeding conveyor belt can be used to feed the material between the quantitative plate 1 1413 and the quantitative plate 2 142. When the material is full, the feeding conveyor belt is stopped. Material, when the feeding conveyor belt stops, there is still material input, which will make the input material exceed the set value between the quantitative plate 1413 and the quantitative plate 2 142. At this time, you only need to start the quantitative motor 131, and when the material overflowing from the quantitative device 14 passes through the barrel cover of the barrel 21 as it rotates, the scraper 1 1414, the scraper 2 1424 and the barrel cover will cooperate to clean and block the overflowing material to the outside of the quantitative device 14, and scrape the material inside the quantitative device 14 flat. At this time, the amount of material in the quantitative device 14 is the initial set amount, and the scraped material can be recycled and reused through an external collection device, without causing waste of materials.

[0045] After passing through the discharge port 23 of the barrel 21, the scraped and leveled metering device 14 is all tilted onto the material conveyor belt 30, and is transported to the mixer for mixing through the material conveyor belt 30. At this time, the first mixing process is completed. By repeating this cycle, the feeding amount can be accurately controlled, so that the concrete mix ratio of each mixing is within the error control range, so that the strength of the same batch of concrete fluctuates within the set range, thereby improving the construction quality.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
