[0040] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0041] Please refer to Figure 1 , Figure 1 which shows a perspective view of the present utility model; Please refer to Figure 2 , Figure 2 which shows a perspective view of the present utility model from another angle; Please refer to Figure 3 , Figure 3 which shows a partial exploded view of the present utility model; Please refer to Figure 4 , Figure 4 which shows a partial cross-section of the present utility model Figure 1 ; Please refer toFigure 5 , Figure 5 shows a partial cross-section of the present utility model Figure 2 ; Please refer to Figure 6 , Figure 6 which shows the present utility model Figure 4 an enlarged view of part A; As Figures 1-6 shown, a mechanism sand quality detection device includes: a base 1, a frame 2 provided on the base 1, a control frame 3 provided on the frame 2, two rotating shafts 4 rotatably connected to the control frame 3 through bearings, a placement box 5 fixed to the brackets of the two rotating shafts 4, a first weighing mechanism 6 installed in the placement box 5, a pretreatment assembly 7 provided above the first weighing mechanism 6, a secondary treatment assembly 8 installed on the frame 2, a second weighing mechanism 9 installed on the base 1, and a collection box 10 provided above the second weighing mechanism 9;

[0042] The first weighing mechanism 6 and the second weighing mechanism 9 are adapted to collect weight data of the mechanism sand material at different stages. Among them, the first weighing mechanism 6 and the second weighing mechanism 9 are existing technical structures that can perform intermediate detection and display weight data;

[0043] The pretreatment assembly 7 is adapted to perform drying treatment on the mechanism sand material;

[0044] The secondary processing component 8 is suitable for dust removal treatment of manufactured sand. During use, the manufactured sand with a constant weight that needs to be quality-tested is put into the pretreatment component 7. The first weighing mechanism 6 provided can weigh the untreated and wet manufactured sand in the pretreatment component 7 and obtain the corresponding weight data. At the same time, the first weighing mechanism 6 will conduct a weighing detection on the pretreatment component 7 every once in a while. Then, during the treatment of the pretreatment component 7, the manufactured sand can be quickly and evenly dried, ensuring the treatment efficiency of the manufactured sand and thus improving the detection efficiency of the quality of the manufactured sand. When the first weighing mechanism 6 detects that the weight of the manufactured sand in the pretreatment component 7 remains unchanged after multiple detections, it means that the drying of the manufactured sand is completed. By comparing the weight data of the manufactured sand in the wet state and the dry state, the weight of the dried moisture can be obtained, and the moisture content of the manufactured sand with a constant weight can be calculated. After preliminary detection, the manufactured sand will fall into the secondary processing component 8 during the flipping of the pretreatment component 7. Under the operation of the secondary processing component 8, the stone powder in the manufactured sand can be separated and collected. The treated manufactured sand will fall into the collection box 10 for storage, and under the detection of the second weighing mechanism 9, the weight data of the treated manufactured sand can be obtained. By comparing the weight of the manufactured sand in the dry state with the quality of the manufactured sand detected by the second weighing mechanism 9, the weight of the stone powder can be obtained, and the stone powder content of the manufactured sand can be calculated. The operation is convenient, and the moisture content and stone powder rate of the manufactured sand can be detected at one time, thus completing the quality detection of the manufactured sand and being easy to use.

[0045] Optionally, the pretreatment component 7 includes a treatment tank 11 that abuts against the first weighing mechanism 6, a heating element 13 installed inside the housing of the treatment tank 11, a stirring shaft 14 arranged inside the treatment tank 11, a first motor 15 installed on the top of the treatment tank 11, a stirring member 16 fixed outside the stirring shaft 14, an auger rod 17 fixedly connected to the lower end of the stirring shaft 14, a control cover 18 arranged outside the auger rod 17 and at the bottom end inside the treatment tank 11, a plurality of feed slots 19 opened at the lower end of the control cover 18, and a feeding component 20 arranged on the top of the treatment tank 11;

[0046] The output end of the first motor 15 is fixedly connected to the top end of the stirring shaft 14;

[0047] The lower end of the stirring member 16 is rotatably connected to the control cover 18. After taking the manufactured sand aggregate that needs to be subjected to quality inspection corresponding to a certain weight and putting it into the treatment tank 11, the heating member 13 inside the housing of the treatment tank 11 is started, and the manufactured sand aggregate in the treatment tank 11 is heated and dried. At the same time, the first motor 15 is started to drive the stirring shaft 14 to rotate, so that the stirring member 16 stirs and mixes the manufactured sand aggregate in the treatment tank 11. Thus, the manufactured sand aggregate in the treatment tank 11 can be evenly dried. And the lower end of the stirring member 16 is rotatably connected to the control cover 18, which can ensure the stability of the stirring member 16 during rotation and improve the service life of the stirring member 16 and the stirring shaft 14. While the stirring shaft 14 is rotating, it will drive the auger rod 17 to rotate, so that the manufactured sand aggregate at the bottom of the treatment tank 11 can enter the control cover 18 through a plurality of feed slots 19, be conveyed upward, and finally fall onto the uppermost layer of the manufactured sand aggregate in the treatment tank 11. Thus, the manufactured sand aggregate is mixed more evenly, while ensuring the drying uniformity of the manufactured sand aggregate, the drying efficiency of the manufactured sand aggregate can be improved, and the efficiency of the quality inspection of the manufactured sand can be effectively improved.

[0048] Optionally, the secondary treatment assembly 8 includes a treatment frame 21 fixed in the frame 2, a plurality of baffle plates 22 arranged obliquely and staggered in the treatment frame 21, a control rod 23 rotatably connected in the treatment frame 21, a plurality of dispersion plates 24 arranged in an upper annular array on the control rod 23, a second motor 25 installed on the outer wall of the treatment frame 21, a dust collection cover 26 communicated with the rear end of the treatment frame 21, a conveying pipe 28 with one end communicated with the dust collection cover 26 and the other end communicated with an external dust suction mechanism, and a filter plate 27 arranged in the dust collection cover 26;

[0049] The output end of the second motor 25 is fixedly connected to one end of the control rod 23;

[0050] The dust collection cover 26 is arranged obliquely;

[0051] The collection box 10 is located directly below the processing box 21. The dust suction mechanism is a common prior art structure for sucking external dust and storing it. After the preliminary processing of the manufactured sand is completed and the weighing is completed by the first weighing sensor, the processing tank 11 is flipped, so that the manufactured sand in the processing tank 11 will fall into the processing box 21. Under the action of several baffle plates 22, the manufactured sand will change its sliding direction multiple times during the falling process and accelerate under the action of gravity. The stone powder in the manufactured sand is dispersed through the collision between the manufactured sand and the inner wall of the processing box 21, the mutual collision between the manufactured sand and the manufactured sand, and the collision between the manufactured sand and several baffle plates 22. When the manufactured sand falls into the processing box 21, the second motor 25 drives the control rod 23 to rotate, so that several dispersion plates 24 can continuously flap the falling manufactured sand, further dispersing the manufactured sand and the stone powder. At the same time, the peripheral dust suction mechanism can generate negative pressure at the dust suction hood, so that the separated stone powder can be transported to the dust suction mechanism through the conveying pipe 28 for collection; the inclined dust collection hood 26 and the filter plate 27 arranged in the dust collection hood 26 can prevent the manufactured sand from falling into the dust collection hood 26 and being sucked into the dust suction mechanism, avoiding the lack of manufactured sand and affecting the accuracy of the quality detection of the manufactured sand.

[0052] Optionally, a manufactured sand quality detection device further includes a third motor 34 fixedly installed on the control frame 3, and two control gears 35 respectively fixed to the output end of the third motor 34 and one of the rotating shafts 4;

[0053] The two control gears 35 are meshed with each other. When the manufactured sand in the processing tank 11 is stirred and dried, the set third motor 34 is started, which can drive one of the control gears 35 to rotate reciprocally, and then meshingly drive the other control gear 35 to rotate synchronously with one of the rotating shafts 4, so that while the manufactured sand in the processing tank 11 is being stirred by the stirring member 16, the processing tank 11 can swing reciprocally around the rotating shaft 4, further improving the mixing effect of the manufactured sand in the processing tank 11, increasing the drying efficiency of the manufactured sand, and ensuring the efficiency of the quality detection of the manufactured sand; at the same time, after the preliminary processing of the manufactured sand in the processing tank 11 is completed, the rotating shaft 4 can drive the placement box 5 to rotate, and then flip the processing tank 11, so that the manufactured sand in the processing tank 11 can fall into the processing box 21 for further processing, eliminating the need for the user to move the processing tank 11 to handle the manufactured sand in the processing tank 11 and reducing the workload of the staff.

[0054] Optionally, a manufactured sand quality detection device further includes several fixing rods 32 fixedly arranged in a circular array on the outer wall of the processing tank 11, and several clamps 33 detachably fixed to the top of the placement box 5 in a circular array;

[0055] The plurality of fixing rods 32 are respectively disposed in the plurality of clamps 33;

[0056] There are movable gaps between the several fixed rods 32 and the several clamps 33. When in use, the restriction on the position of the several fixed rods 32 by the several clamps 33 can complete the restriction on the position of the processing tank 11, and then when the processing tank 11 is turned over for unloading, the processing tank 11 will not be separated from the placement box 5; at the same time, the restriction on the position of the several fixed rods 32 is released by removing the several clamps 33, so as to facilitate the separation of the processing tank 11 from the placement box 5. At this time, the first weighing mechanism 6 and the pretreatment component 7 can be inspected and maintained, which is convenient to use. There is a movable gap between the fixed rods 32 and the clamps 33, which is convenient for the movement of the processing tank 11 in the placement box 5, and then it is convenient for the first weighing sensor to detect the weight of the processing tank 11 and the machine-made sand material inside.

[0057] Optionally, the feeding component 20 includes a feeding pipe 29 connected to the top of the processing tank 11, a cover 30 and an electric push rod 31 hinged on the top of the processing tank 11;

[0058] The telescopic end of the electric push rod 31 is hinged to the upper surface of the cover body 30. When the processing tank 11 is flipped over and the cover body 30 reaches directly above the processing frame 21, the electric push rod 31 is started, and the cover body 30 can be controlled to rotate and open, so that the machine-made sand in the processing tank 11 falls into the processing frame 21. The rotation angle of the cover body 30 is controlled to facilitate the adjustment of the discharge efficiency of the machine-made sand in the processing tank 11. While ensuring that the machine-made sand can accurately fall into the processing frame 21, it is prevented from falling out of the processing tank 11 in advance when the processing tank 11 is flipped and falling outside the processing frame 21, thereby improving the accuracy of the data of the machine-made sand quality detection.

[0059] Optionally, the pre-treatment component 7 further includes a plurality of scraping strips 36 fixed in an annular array on the stirring member 16;

[0060] The plurality of scraper strips 36 are all against the inner wall of the processing tank 11. When the machine-made sand in the processing tank 11 is poured into the processing frame 21, the stirring shaft 14 rotates to drive the stirring member 16 to move in the processing tank 11, so that the plurality of scraper strips 36 can clean the inner wall of the processing tank 11, thereby ensuring that the machine-made sand in the processing tank 11 can be effectively discharged into the processing frame 21, ensuring the relative cleanliness of the processing tank 11, avoiding the machine-made sand from adhering to the inner wall of the processing tank 11, and facilitating the subsequent detection of the machine-made sand.

[0061] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
