Description

Technical Field

[0001] The utility model relates to the technical field of cement-stabilized crushed stone production, and more specifically to a device capable of controlling the amount of cement used in cement-stabilized crushed stone. Background Art

[0002] Cement-stabilized crushed stone material uses crushed stone with a certain grade as aggregate, combined with cementitious materials (such as cement, etc.) and a certain amount of mortar volume to fill its gaps. It mainly relies on the interlocking principle between crushed stones to form a mixture with certain mechanical strength and density. Because of the effect of cement, it has a higher strength at the beginning, and as the age increases, the strength increases and forms a whole. Because of its high strength and rigidity, it is widely used in highway base construction.

[0003] A quantitative feeding control device for cement production is disclosed in the Chinese utility model patent application number: CN220011416U, which includes a storage box, a feeding pipe is fixedly connected to the middle of the lower surface of the storage box, and a stirring mechanism is arranged inside the storage box, and the stirring mechanism includes a motor, a rotating shaft, a spiral stirring blade, and a spiral blade; one side of the outer wall of the motor is fixedly connected to the upper surface of the storage box, and the output end of the motor is fixedly connected to the rotating shaft. Although a stirring device is arranged inside the quantitative feeding control device for cement production, it lacks a structure for quantitatively feeding the added materials, and a large amount of cement will accumulate inside the stirring device, resulting in a decrease in stirring quality and a prolongation of stirring time.

[0004] The following problems still exist when producing cement stabilized gravel materials:

[0005] During production and mixing, cement is usually added into the mixing tank all at once, which will cause a large amount of cement to accumulate in the mixing tank. Adding a large amount of cement at one time may cause local uneven mixing, especially in the case of low water-cement ratio. The wrapping and wetting between cement and aggregate may not be sufficient, resulting in reduced quality of the finished product after production, and also will lead to extended production time. Although some equipment has added a device that can add cement quantitatively to achieve the effect of multiple quantitative additions, it is not possible to automatically adjust the amount of cement added each time according to the weight of the cement.

[0006] Therefore, it is necessary to propose a device that can control the amount of cement-stabilized crushed stone cement to solve the above problems. Utility Model Content

[0036] See also Figure 1-9 A device for controlling the amount of cement used to stabilize crushed stone includes a tank body 101 and a driving device 102. The interior of the tank body 101 is a stirring area. The cement and aggregate inside are uniformly mixed by the rotation of a stirring blade 122 and a discharging blade 123. A top cover 103 is fixedly connected to the top of the tank body 101. The top cover 103 and the tank body 101 are sealed and welded.

The rod 112 drives the arc plate 113 and the material rod 114 to rotate, and the bottom drives the stirring blade 122 and the discharging blade 123 to rotate. A support plate 107 is fixedly connected to the inner wall of the tank body 101, and a fixed tank 108 is fixedly connected to the top of the support plate 107. The support plate 107 is used to support the fixed tank 108, so that when the storage tank 106 moves up and down, the fixed tank 108 can remain stationary. The inner wall of the top cover 103 is slidably connected to the conical plate 105, and the bottom of the conical plate 105 is fixedly connected to the storage tank 106 that is slidably connected to the fixed tank 108. The storage tank 106 slides up and down inside the fixed tank 108, so that the strip groove 110 on the outer wall can cooperate with the material drop groove 111, so as to achieve the effect of controlling the cement discharge amount;

[0037] refer to Figure 5 , Figure 6 and Fig. 9 A spring 109 is connected between the storage tank 106 and the fixed tank 108. The spring 109 is used to push the storage tank 106 and the conical plate 105 to move upward. Only when there is cement or other raw materials on the conical plate 105, the conical plate 105 and the storage tank 106 will move downward due to the action of gravity. At the same time, the spring 109 at the bottom is compressed. A strip groove 110 that runs through the entirety is provided on the outer wall of the storage tank 106. The blanking groove 111 is overlapped with the strip groove 110. The initial position of the strip groove 110 is at the top of the triangular blanking groove 111. The channel formed by the strip groove 110 and the blanking groove 111 is the pointed part at the top of the blanking groove 111. When the spring 109 is fully compressed, the strip groove 110 is parallel to the bottom of the blanking groove 111. At this time, the formed channel is the largest. A blanking groove 111 that runs through the entirety is provided on the outer wall of the fixed tank 108.

[0038] refer to Figures 5 to 9 The outer wall of the rotating rod 104 is connected to a lifting rod 112 which slides up and down. The lifting rod 112 is pushed by the top spring 109 and always fits with the storage tank 106. The bottom end of the outer wall of the lifting rod 112 is fixedly connected to an arc plate 113 located inside the storage tank 106. The material in the storage tank 106 is pushed by the rotation of the arc plate 113 and is pushed out of the storage tank 106. The top of the outer wall of the lifting rod 112 is fixedly connected to a material rod 114 which moves along the surface of the conical plate 105.

[0039] refer to Figures 5 to 8 An external spline portion 115 is provided at the top of the rotating rod 104, and the lifting rod 112 is slidably connected to the external spline portion 115 through the internal spline portion 116, and can slide up and down on the outer wall of the rotating rod 104 and rotate with the rotating rod 104. An internal spline portion 116 that slides up and down on the external spline portion 115 is provided inside the top end of the lifting rod 112, and a top plate 117 is fixedly connected to the top end of the external spline portion 115. The top plate 117 plays a supporting role and is used to support the spring 109 to extend downward. The spring 109 is connected between the lifting rod 112 and the top plate 117.

[0040] Specifically, refer to Figures 1 to 3 A support frame 118 and a feed pipe 119 are provided on the outside of the tank body 101. The support frame 118 is used to support the tank body 101 and is connected to the tank body 101 through a weighing device 121. A horizontal plate 120 is arranged in a circular array on the outer wall of the tank body 101. The horizontal plate 120 is used to connect the weighing device 121. The weighing device 121 is fixedly connected between the top of the horizontal plate 120 and the support frame 118.

[0041] Specifically, refer to Figures 1 to 4A feed hose 124 is fixedly connected between the feed pipe 119 and the top cover 103. The feed hose 124 can be extended. When the top cover 103 moves downward, the feed hose 124 can always be connected to the top cover 103 by extension, and the feed pipe 119 is connected to the external feeding device.

[0042] Specifically, refer to Figure 2 and Figure 3 The bottom end of the rotating rod 104 is fixedly connected with a stirring blade 122 and a discharging blade 123. The stirring blade 122 is located in the tank body 101 and can evenly stir the material inside. The discharging blade 123 is located in the discharging pipe at the bottom of the tank body 101 and is used to stir the material in the discharging pipe. The discharging blade 123 is located in the discharging port of the tank body 101, and the stirring blade 122 is located in the tank body 101.

[0043] Specifically, refer to Figure 5 and Figure 6 A blocking hose 125 is also connected between the storage tank 106 and the fixed tank 108. The blocking hose 125 can prevent materials from falling into the area between the storage tank 106 and the fixed tank 108. When materials fall into the area between the storage tank 106 and the fixed tank 108, it will cause the storage tank 106 to get stuck in moving up and down. The blocking hose 125 is located outside the spring 109.

[0044] Specifically, refer to Fig. 9 The blanking groove 111 is triangular in shape, and the position of the strip groove 110 overlaps with the blanking groove 111. The initial position of the strip groove 110 is at the top of the triangle. As the spring 109 is compressed, the strip groove 110 will move downward and finally be flush with the bottom of the triangle. The length of the strip groove 110 is the same as the length of the bottom of the blanking groove 111.

[0045] Specifically, refer to Figures 3 to 6 A guide frame 126 is fixedly connected to the inner wall of the top cover 103. The guide frame 126 is used to stabilize the up and down movement of the conical plate 105. A groove corresponding to the guide frame 126 is opened on the outer wall of the conical plate. The conical plate 105 moves on the guide frame 126 through the grooves around it and can slide up and down along the guide frame 126.

[0046] In this embodiment, the feed pipe 119 on the top cover 103 is used to connect with an external feed device, and the discharge port of the feed pipe 119 is connected to the top cover 103 through a feed hose 124, so that materials such as cement or aggregate can be added into the tank body 101 through the feed pipe 119. A transverse plate 120 is connected to the outer wall of the tank body 101, and a weighing device 121 on the top of the transverse plate 120 is connected to the support frame 118. The weighing device 121 can weigh the total weight of the device, so as to know the weight of the added material. When the tank body 101 moves downward due to the weight, the feed hose 124 on the top will be stretched, so that the top cover 103 will not be separated from the feed pipe 119;

[0047] When in use, the driving device 102 is started, and the driving device 102 drives the stirring blade 122 and the discharging blade 123 to stir inside the tank body 101 through the rotating rod 104. The cement added into the equipment will first fall on the top of the conical plate 105, and move along the curved surface of the conical plate 105 to the storage tank 106. The conical plate 105 will fall due to the weight of the cement, driving the storage tank 106 to move downward. At this time, the spring 109 and the blocking hose 125 between the storage tank 106 and the fixed tank 108 are compressed, and the strip groove 110 on the storage tank 106 will move downward together. The initial position of the strip groove 110 is located at the top part of the triangular trough 111. The cement can pass through the hole at the top of the triangle. As the strip groove 110 moves downward, the overlapped portion of the strip groove 110 and the material drop groove 111 becomes larger, and the hole through which cement can pass also becomes larger. When the rotating rod 104 rotates, the arc plate 113 is driven to rotate inside the storage tank 106. The rotating arc plate 113 pushes the cement in the storage tank 106 out of the storage tank 106 through the hole formed by the strip groove 110 and the material drop groove 111, and then the cement falls into the stirring area inside the tank body 101, thereby achieving the effect of quantitative addition of cement. The conical plate 105 can move downward with the weight of the cement. The heavier the added weight, the greater the distance the conical plate 105 moves downward, the larger the channel formed by the strip groove 110 and the material drop groove 111, and the more cement can pass through each time.

[0048] When the conical plate 105 moves downward, the lifting rod 112 is pushed by the top spring 109, so that the material rod 114 and the conical plate 105 are always kept in close contact with each other, and the outer spline part 115 on the outer wall of the rotating rod 104 cooperates with the inner spline part 116 on the lifting rod 112, so that the rotating rod 104 can drive the lifting rod 112 to rotate, and the lifting rod 112 drives the arc plate 113 on the outer wall and the material rod 114 to rotate, and the arc plate 113 at the bottom pushes the material in the storage tank 106 into the tank body 101 by rotating, and the top material rod 114 can promote the cement on the conical plate 105 when rotating, so as to speed up the speed of cement moving to the storage tank 106, and the guide frame 126 is used to stabilize the up and down movement of the conical plate 105, and the blocking hose 125 prevents the cement from falling into the space between the storage tank 106 and the fixed tank 108, so as to avoid the storage tank 106 from getting stuck when it is lifted or lowered;

[0049] The cement falling into the tank body 101 is mixed with materials such as aggregates, and the rotating rod 104 drives the stirring blades 122 and the discharging blades 123 at the bottom to continuously stir the cement-stabilized gravel materials. The discharging blades 123 can stir the inside of the discharging pipe at the bottom of the tank body 101 to avoid the situation where the materials in the discharging pipe are not evenly stirred.

[0050] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
