Abstract
Description
Technical Field
[0001] The utility model relates to cement filling equipment, in particular to the structure of cement filling equipment. Background Art
[0002] Cement is a powdery hydraulic inorganic gelling material. It can form a slurry after adding water and mixing. It can harden in the air or in water. It can firmly bond sand, stone and other materials together. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water.
[0003] In actual production, cement filling equipment is required to quantitatively fill cement from cement silos into cement tank trucks or ton bags.
[0004] The main structure of the existing cement filling equipment is the discharge pipe and the gate valve installed at the bottom of the cement silo. During filling, the staff needs to operate the gate valve to discharge the material according to experience and the measured value of the weighing equipment to achieve the specified quality.
[0005] However, due to the wide channel formed after the gate valve is opened, and the cement is easily compressed and agglomerated, resulting in poor fluidity, it is difficult for workers to accurately control the quality of the cement when discharging. If too little cement is poured in, it does not comply with business rules and will be punished by the supervisory department. Too much cement will harm the interests of the company and may also lead to excessive transportation and overloading. Utility Model Content
[0006] The utility model aims to solve the problem that it is difficult for workers to accurately control the quality of filled cement when discharging materials using existing cement filling equipment.
[0007] For the above purpose, the utility model provides a cement filling device. The cement filling device is installed at the bottom of the cement silo 00 and is used to load the cement tank in the cement silo 00 into a ton bag or a cement tank truck, including: a main body 2, a temporary storage tank 1, and the main body 2 includes: a shell 21, a left unloading gear 22, a right unloading gear 23, a unloading motor 24, and a control system.

[0013] Therefore, by rotating the left feeding gear 22 and the right feeding gear 23 inward, the tooth tips of the two can crush the cement lumps while pushing the cement downward, so that the cement is evenly fed. In the process of filling cement, the quality of cement poured into the cement tanker 4 is directly related to the number of revolutions of the left feeding gear 22 and the right feeding gear 23.

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. The following description is a concretization of the claims of the present invention. Embodiment 1
[0031] The present embodiment is a cement filling device for filling cement into a cement tank truck.
[0032] Figure 1 The structure of the cement filling equipment installed at the bottom discharge cone 001 of the cement silo 00 is shown, and the cement filling equipment includes: a temporary storage tank 1, a main body 2, a slide rail 12, an adjustment motor 122, an adjustment gear 121, an adjustment tooth plate 13, a first limit device 124, and a control system (not shown in the figure).
[0033] Figure 2 The structure and position relationship of the temporary storage tank, the main body and the slide rail are shown. Figure 3 The structure of the slide bar at the bottom of the temporary storage tank is shown. Figure 4 shows the internal structure of the housing, Figure 5 is along Figure 4 The structure of the middle part of the shell cut along AA.
[0034] Combination Figure 2 and Figure 4 As shown, the main body 2 includes: a shell 21, a left feeding gear 22, a right feeding gear 23, and a feeding motor 241.
[0035] like Figure 3 As shown, the temporary storage tank 1 is a cylinder open at the top and bottom, see Figure 1 The upper end of the temporary storage tank 1 is softly connected to the bottom of the cement silo 00 through a flexible cloth 002.
[0036] See also Figure 4 The shell 21 is a hollow square cylinder with a hollow interior to form a material passing channel.
[0037] The upper end of the shell 21 opens outward to form a funnel-shaped feed opening 201, and a Figure 3 The temporary storage tank 1 shown, that is, the feed port 201 is connected to the lower end of the temporary storage tank 1. The lower end of the shell 21 is narrowed to form a discharge port 202, such as Figure 1 As shown, when in use, the discharge port 202 faces the inlet 41 of the cement tank truck 4 .
[0038] like Figure 4 , Figure 5As shown, the middle section 203 of the housing 21 bulges to the left and right sides, so that an installation space 203 is formed in the material transfer channel 200. Figure 5 As shown, the left feeding gear 22 and the right feeding gear 23 are arranged horizontally, have the same shape and the same height of the center lines L1 and L2, and the outer tooth tips are respectively fitted with the bulging parts, so that cement will not leak from both sides.
[0039] See also Figure 4 The front ends of the left feeding gear 22 and the right feeding gear 23 are connected to the front side wall of the housing 21 through bearings, and the rear ends respectively pass through the housing 21 and are connected to the feeding motor 24 through a synchronous transmission device. The control system can control the feeding motor 24 to drive the left feeding gear 22 and the right feeding gear 23 to rotate inward at the same speed, that is, respectively according to Figure 5 The small and medium arrows a and small arrow b indicate rotation.
[0040] The tooth tips of the left feeding gear 22 and the right feeding gear 23 correspond to each other, and when they rotate to the position of the plane P1 formed by the center lines L1 and L2 (for example, the tooth tips 20a and 20b are located at Figure 5 In the state shown in FIG, the ends of the tooth tips are in contact with each other, so that the material passage is closed, that is, from a top view, the left feed gear 22 and the right feed gear 23 can cover the narrower portion 204 of the housing 21 located on the upper side of the middle section 203 thereof.
[0041] like Figure 1 , 2 As shown, two parallel horizontal straight rod slide rails 12 are fixed to the bottom of the cement silo 00 by a bracket (the bracket is not shown). Figure 2 , 3 As shown, two slide bars 11 matching the shape of the slide rail 12 are arranged at the bottom of the temporary storage tank 1 , and the slide bars 11 are slidably connected to the slide rail 12 , that is, the temporary storage tank 1 and the main body 2 can slide forward and backward along the slide rail 12 .
[0042] like Figure 1 , 2 As shown, an adjusting motor 122 and two adjusting gears 121 connected by straight rods are fixedly provided at the rear end of the slide rail 12, and a control system is connected to the adjusting motor 122 and can control the adjusting motor 122. The adjusting gear 121 is fixed to the rotating shaft of the adjusting motor 122 and is mounted on the upper side of the slide rail 12 by a fixing member 1211. An adjusting tooth plate 13 whose shape matches the adjusting gear 121 is fixedly provided at the rear side of the temporary storage tank 1, and the adjusting gear 121 meshes with the adjusting tooth plate 13.
[0043] like Figure 1As shown, first limiting devices 124 are respectively provided at both ends of the slide rail 12 , and the first limiting devices 124 are used to limit the movement range of the slide bar 11 at the lower end of the temporary storage tank 1 to prevent it from falling from both ends of the slide rail 12 .
[0044] The control system can control the rotation of the unloading motor 241 and the adjusting motor 122 .
[0045] When in use, cement falls by its own gravity, passes through the discharge cone 001 and the surrounding cloth 002 from the cement silo 00 and enters the temporary storage tank 1.
[0046] The staff first uses the control system to control the adjusting motor 122. The rotating shaft of the adjusting motor 122 drives the adjusting gear 121 to rotate, thereby driving the adjusting gear plate 13 to adjust the temporary storage tank 1 and the main body 2 to slide on the slide rail 12, that is, adjust the position of the temporary storage tank 1 and the main body 2, so that the discharge port 202 is adjusted to be directly above the inlet 41 of the cement tank truck 4.
[0047] Afterwards, the staff manipulates the control system to turn on the feeding motor 241, causing the left feeding gear 22 and the right feeding gear 23 to rotate inward at the same speed (according to Figure 5 The small arrow a and the small arrow b rotate at the same speed). The cement in the temporary storage tank 1 enters the main body 2 from the feed port 202, and falls evenly driven by the left and right feeding gears 22 and 23 rotating at a uniform speed, and is discharged from the discharge port 202, and then enters the cement tank truck 4 from the inlet 41.
[0048] Therefore, by rotating the left feeding gear 22 and the right feeding gear 23 inward, the tooth tips of the two can crush the cement lumps while pushing the cement downward, so that the cement is evenly fed. In the process of filling cement, the quality of cement poured into the cement tanker 4 is directly related to the number of revolutions of the left feeding gear 22 and the right feeding gear 23. The staff only needs to control the number of revolutions of the feeding motor 241 to accurately control the quality of the filled cement.
[0049] Modification 1
[0050] This variation is illustrated as a cement filling device for filling cement into ton bags. After a fixed amount of cement is poured into the ton bags, the bags can be made into bagged cement for storage, transportation, and sale.
[0051] Figure 6 The structure of the cement filling equipment of this modified example is shown as follows: Figure 6 As shown, the structure of this modification is basically the same as that of the first embodiment, and the only difference is that:
[0052] like Figure 6As shown, three ton bags 3 are placed along the slide rail 12 below the cement silo 00, and a platform scale 31 is arranged below each ton bag 3. Universal wheels are also arranged below the platform scale 31 for movement.
[0053] A plurality of second limiting devices 123 are fixedly mounted on the slide rail 12. The positions of the second limiting devices 123 correspond to the ton bags. The second limiting devices 123 are infrared sensors.
[0054] The control system receives the measurement value information of the platform scale 31 to control the unloading motor 24 and the adjustment motor 122 .
[0055] The method of use of this variation is basically the same as that of the first embodiment, with the only difference being that, when in use, the control system is used to operate the adjusting motor 122 to make the temporary storage tank 1 and the main body 2 slide on the slide rail 12, and the control system pauses the adjusting motor 122 when receiving the signal that the second limiting device 123 detects the temporary storage tank 1, and temporarily fixes the cement filling equipment directly above the ton bag 3.
[0056] Afterwards, the control system is used to start the unloading motor 241, so that the left unloading gear 22 and the right unloading gear 23 rotate a specified number of times, so that the ton bag 3 is filled with cement of a standard quality.
[0057] Afterwards, the control system is used to compare the measured value of the platform scale 31 with the standard mass. If they are equal, the control system operates the regulating motor 122 to make the temporary storage tank 1 and the main body 2 continue to slide on the slide rail 12 to the next ton bag... and so on; if they are not equal, the staff is reminded, and the staff uses the control system to operate the left feeding gear 22 and the right feeding gear 23 to continue to rotate a small amount of a predetermined number according to the reminder, until the cement poured into the ton bag 3 reaches the standard mass.
[0058] Therefore, the utility model can ensure that the quality of cement poured into the ton bag 3 meets the standard, and there will be no situation of excessive filling and damage to the interests of the enterprise.
[0059] In summary, the cement filling equipment has a simple structure and is easy to use, and can solve the problem that it is difficult for workers to accurately control the quality of the filled cement when discharging materials using existing cement filling equipment.
