Description

Technical Field

[0001] The utility model relates to a proportioning device for machine-made sand concrete, belonging to the technical field of building material processing. Background Art

[0002] Machine-made sand is made by crushing and processing stones (such as river pebbles, granite, cobblestones, tailings, etc.) through sand-making equipment. It has various specification types, and medium-coarse sand is mostly used in concrete. Its particle size distribution is stable and adjustable, the surface is rough, the edges and corners are sharp, and it contains a certain amount of stone powder. Due to its good physical properties and wide raw material sources, machine-made sand has become an important and indispensable material in the modern construction industry.

[0003] When making concrete with machine-made sand, reasonable proportioning is required. The proportioning of the content of machine-made sand and stone powder is often controlled manually, which is difficult for inexperienced construction workers to accurately grasp the proportioning share. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a proportioning device for machine-made sand concrete, which solves the problem that the proportioning of each component is not accurate enough when making concrete with machine-made sand in the prior art.

[0005] The technical problem to be solved by the utility model is achieved by the following technical solutions: A proportioning device for machine-made sand concrete includes a mixing tank. The upper end of the mixing tank is a feed inlet, and a mixing component is arranged on the feed inlet. The lower end of the mixing tank is provided with a discharge outlet, and a discharge component is arranged at the bottom of the discharge outlet.

[0006] A number of vertical sliding rods, on which connecting pieces are slidably sleeved, and the connecting pieces are connected to the outer wall surface of the mixing tank.

[0007] Buffer springs are sleeved on the vertical sliding rods, and scale lines are marked on each vertical sliding rod.

[0008] By adopting the above technical solutions, the weight of the raw materials added to the mixing tank can be accurately determined, so as to accurately control the content of each component used for making concrete. During the process of adding each component of raw materials into the mixing tank, since the mixing tank is supported by buffer springs as a whole, during the process of adding raw materials, the mixing tank will slowly descend as the weight of the raw materials in its inner cavity increases. The weight of the added raw materials can be judged by the amount of the descending height, so that the concrete mixing personnel can accurately control the content of each portion of the added raw materials through the pointer indication on the connecting piece, making the production of concrete more convenient and of higher quality.

[0009] The utility model is further arranged as: A pointer for indicating the scale line is arranged on the connecting piece.

[0010] By adopting the above technical solution, the pointer can more accurately judge the descending height of the mixing tank, so that the construction personnel can more accurately control the raw materials.

[0011] The present utility model is further arranged as follows: The mixing assembly includes a plurality of fixed rods fixed on the discharge port. One end of the fixed rod is connected to the outer wall of the mixing tank, and the other ends converge at the center of the mixing tank. A mixing motor is arranged above the convergence point of the fixed rods. The lower end of the mixing motor is connected to a mixing shaft, and mixing rods are arranged on the mixing shaft.

[0012] By adopting the above technical solution, the raw materials in the mixing tank can be fully mixed, accelerating the formation of concrete. After a number of connecting rods converge at the center of the feeding port, the mixing shaft extending from the convergence center to the bottom of the inner cavity of the mixing tank is connected to the motor for driving. Through the driving of the motor, the mixing rods connected to the lower end of the mixing shaft can be driven to rotate, mixing and blending the added raw materials.

[0013] The present utility model is further arranged as follows: There are at least three vertical sliding rods. The mixing tank is slidably installed between the vertical sliding rods through a connecting piece, and the distance between each vertical sliding rod and the outer wall of the mixing tank is the same.

[0014] By adopting the above technical solution, the mixing tank can be stably limited between all the vertical sliding rods. During the feeding and discharging process of the mixing tank, it can smoothly slide in the direction of the vertical sliding rods through the connecting piece, so that the movement of the mixing tank in the vertical direction is more accurate and the lateral deviation is reduced.

[0015] The present utility model is further arranged as follows: The discharging assembly includes a bottom support platform. A liftable material receiving groove is arranged on the upper end of the support platform. The material receiving groove is connected to a material discharge channel, and the inclination angle between the material discharge channel and the bottom surface is greater than 25 degrees.

[0016] By adopting the above technical solution, the concrete discharged from the discharge port can be smoothly discharged. The inclined material discharge channel enables the concrete to automatically slide to the bottom of the material discharge channel under the action of gravity, preventing the concrete from adhering to the material discharge channel.

[0017] The present utility model is further arranged as follows: A rotatable rotating shaft is arranged at the edge of the discharge port. A circular baffle is arranged through the rotating shaft, and the rotating shaft is connected to the side of the circular baffle.

[0018] By adopting the above technical solution, the circular baffle rotates around the rotating shaft to realize the opening and closing of the discharge port. The amount and time of discharging can be freely controlled. After the raw materials in the mixing tank are fully mixed and formed, the circular baffle at the center can be automatically opened for discharging, so as to accurately control the overall quality of the concrete.

[0019] The present utility model is further configured as follows: a rotatable discharge shaft is arranged at the center of the receiving groove, and discharge plates are arranged on the discharge shaft.

[0020] By adopting the above technical solution, the concrete in the receiving groove can be quickly discharged into the material discharge channel, and it can prevent the concrete from adhering to the inside of the receiving groove and solidifying into blocks.

[0021] The beneficial effect of the present utility model is that through the arrangement of the vertical sliding rod and the buffer spring, when various proportioned raw materials are added to the mixing pool, the moving distance of the mixing pool in the vertical direction can be directly observed through the scale line arranged on the vertical sliding rod and the pointer arranged on the connecting piece. The weight of the raw materials added to the mixing pool can be reflected by the moving distance. The proportioning personnel of the concrete can more accurately control the addition amount of each raw material component, thereby making the quality of the prepared concrete higher.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to facilitate understanding of the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below with reference to specific drawings.

[0028] As Figure 1 shown, a mechanism sand concrete proportioning device includes a mixing pool 1. The upper end of the mixing pool 1 is a feed inlet 101, and a mixing assembly 2 is arranged on the feed inlet 101. The lower end of the mixing pool 1 is provided with a discharge outlet 102, and a discharging assembly 3 is arranged at the bottom of the discharge outlet 102.

[0029] Among them, the mixing tank 1 is a whole tank body. The upper end face is a completely open feeding port 101, and the lower end contracts towards the center, leaving a discharge port 102 with a smaller diameter. At the position of the discharge port 102 of the mixing tank 1, the inner cavity wall surface is an inverted conical structure, which is conducive to the concrete converging to the discharge port 102 during discharging, and can effectively prevent a large amount of concrete from remaining in the mixing tank 1.

[0030] A number of vertical sliding rods 4, and a connecting piece 5 is slidably sleeved on the vertical sliding rod 4, and the connecting piece 5 is connected to the outer wall surface of the mixing tank 1.

[0031] In this embodiment, the vertical sliding rod 4 is fixed to the ground by bolts. The buffer spring 6 is sleeved on the vertical sliding rod 4. The lower end of the buffer spring 6 is connected to the bottom end of the vertical sliding rod 4, and the upper end is connected to the connecting piece 5. Among them, the main body of the connecting piece 5 is a disc shape with a through hole opened in the center, and is slidably sleeved on the vertical sliding rod 4 through the through hole opened in the center. An extension plate extends from the main body to the outside, and is fixedly connected to the outer wall surface of the mixing tank 1 through the extended extension plate, and the two are connected by welding.

[0032] When adding concrete raw materials into the mixing tank 1 through the feeding port 101, the mixing tank 1 moves downward continuously due to the increasing gravity, driving the connecting piece 5 to compress the buffer spring 6. When the addition of raw materials stops. The mixing tank 1 stops descending. At this time, the difference between the value of the scale line 7 indicated by the pointer 8 and the initial value of the scale line 7 is the descending height of the mixing tank 1. From the descending height of the mixing tank 1, it can be deduced that the weight of the added raw materials is proportional to the compression amount of the spring and the magnitude of the external force applied to the spring. Before and after adding different raw materials each time, first record the corresponding scale, so as to accurately control the addition components of each portion of raw materials and ensure the processing quality of concrete.

[0033] As Figure 4 shown, a buffer spring 6 is sleeved on the vertical sliding rod 4, and a scale line 7 is marked on each vertical sliding rod 4, and a pointer 8 for indicating the scale line 7 is provided on the connecting piece 5.

[0034] The setting of the scale line 7 can accurately determine the weight of the raw materials added into the mixing tank 1, so as to accurately control the content of each component used for concrete production. Through the pointer 8, the descending height of the mixing tank 1 can be judged more accurately, so that the construction personnel can control the raw materials more precisely.

[0035] As Figure 1 shown, the mixing assembly 2 includes a number of fixing rods 201 fixed on the discharge port 102.

[0036] In this embodiment, the number of fixing rods 201 is set to three. One end of each fixing rod 201 is connected to the outer wall of the mixing tank 1, and the other ends converge at the center of the mixing tank 1. Above the convergence point of the fixing rods 201, there is a mixing motor 202. The lower end of the mixing motor 202 is connected to a mixing shaft 203, and mixing rods 204 are arranged on the mixing shaft 203.

[0037] The mixing motor 202 drives the mixing shaft 203 to rotate, driving the mixing rods 204 to stir and mix the added raw materials. During the mixing process, the mixing motor 202 can rotate forward and backward to fully mix the raw materials.

[0038] In this embodiment, the number of vertical sliding rods 4 is set to four. The mixing tank 1 is slidably installed between the vertical sliding rods 4 through a connecting member 5. The distance between each vertical sliding rod 4 and the outer wall of the mixing tank 1 is the same. The mixing tank 1 can be stably limited between all the vertical sliding rods 4. During the loading and unloading process of the mixing tank 1, it can smoothly slide in the direction of the vertical sliding rods 4 through the connecting member 5, making the movement of the mixing tank 1 in the vertical direction more accurate and reducing the lateral deviation.

[0039] As Figure 2 and Figure 3 shown, the discharging assembly 3 includes a bottom support platform 301. An elevating material receiving trough 302 is arranged at the upper end of the support platform 301. The material receiving trough 302 is connected to a material discharging channel 303, and the inclination angle between the material discharging channel 303 and the bottom surface is greater than 25 degrees.

[0040] Among them, the material receiving trough 302 is a cylindrical groove, and an opening is arranged on one side to be connected to the material discharging channel 303. The material receiving trough 302 is supported by the support platform 301, and its support height can increase as the mixing chamber rises. The material receiving trough 302 is mainly used to receive the concrete discharged from the discharging port 102. Through the setting of the receiving trough, the falling of the concrete can be quickly collected and will not flow around after falling.

[0041] In this embodiment, the support platform 301 is provided with an inner cavity, and a lifting electric cylinder is arranged in the inner cavity of the support platform 301. The lifting electric cylinder can drive the entire receiving trough to rise and fall, so as to adapt to the situation that the mixing tank 1 rises due to the reduction of its own gravity during the discharging process.

[0042] A rotatable rotating shaft 9 is arranged at the edge of the discharging port 102. A circular baffle 10 is arranged through the rotating shaft 9, and the rotating shaft 9 is connected to the side of the circular baffle 10. The circular baffle 10 rotates around the rotating shaft 9 to open and close the discharging port 102. The amount and time of discharging can be freely controlled. After the raw materials in the mixing tank 1 are fully mixed, the circular baffle at the center can be automatically opened for discharging, so as to accurately control the overall quality of the concrete.

[0043] Among them, the circular baffle 10 is driven by a baffle motor 11, and the baffle motor 11 can control the positive and reverse rotation of the circular baffle 10.

[0044] A rotatable discharge shaft 305 is provided at the center of the receiving groove, and a discharge plate 304 is provided on the discharge shaft 305.

[0045] In this embodiment, a motor for driving the rotation of the discharge shaft 305 is provided at the lower end of the receiving groove. The discharge shaft 305 is driven to rotate by the motor, driving the discharge plate 304 to continuously rotate in the receiving groove, so as to continuously dial the concrete falling into the receiving groove into the material discharge channel 303.

[0046] Working principle: During the use of the device, the weight of the added raw materials is calculated by observing and recording the compression amount of the buffer spring 6 before and after each addition of raw materials, so as to more accurately control the content of each raw material component, ensuring the forming quality of the cement.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
