Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of weighing devices, and in particular relates to a quick quality detection device for sandstone aggregates. Background Art
[0002] Sand and gravel aggregate is a general term for materials such as sand, pebbles (gravel), crushed stone, block stone, and material stone in water conservancy projects. Sand and gravel aggregate is the main building material for structures such as concrete and stacked stones in water conservancy projects.
[0003] Screening analysis, abbreviated as screening analysis, refers to the screening work to determine the particle size composition of loose solid materials, that is, the particle size analysis method of dividing the material into several levels according to the particle size by screening method. In the screening analysis test of sand and gravel aggregates, it is necessary to weigh the weight of sand and gravel aggregates of different particle sizes after screening. When weighing, the sand and gravel aggregates of the former particle size are not taken out from the weighing tray. The weight of the sand and gravel aggregates of the latter particle size is obtained by calculating the mass increased each time. This causes the sand and gravel aggregates to mix with each other when weighing. Once the data recording is wrong, the problem of re-screening will be faced. Utility Model Content
[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a quick quality detection device for sand and gravel aggregates.
[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:
[0006] A quick-type sand and gravel aggregate quality detection device comprises an electronic scale body, a large tray and a plurality of small trays;
[0007] The large pallet is provided with a plurality of pallet slots for placing small pallets. Both ends of the small pallet in the length direction are connected with pressure rings, and the pressure rings press the weight adjustment block onto the small pallet. The sum of the weights of the corresponding small pallet, pressure ring and weight adjustment block in each pallet slot is a fixed value.
[0008] It is further defined that a push button is installed inside the tray slot, and after the small tray is placed in the tray slot, the push button is triggered, and each of the push buttons is connected to an LED light, and the LED light has two lighting colors and is selected by the push button. With such a structural design, when the small tray is placed in place for the first time, the push button is triggered and the LED light displays red. When the small tray is loaded with sand and gravel aggregates and is picked up and put down, the push button is triggered for the second time, and the LED light displays green, indicating that the sand and gravel aggregates in the small tray have been measured.
[0009] It is further defined that the inner cavity shape of the small tray is an isosceles trapezoid that is larger at the top and smaller at the bottom, the outer surface shape of the small tray is also an isosceles trapezoid, the depth of the tray groove is greater than the height of the small tray, and the tray groove is provided with a chamfer that matches the outer shape of the small tray. With such a structural design, the inner cavity shape of the small tray is designed to be an isosceles trapezoid, which is convenient for putting in and taking out sand and gravel aggregates. The outer shape of the small tray is also an isosceles trapezoid because the isosceles trapezoid has two inclined surfaces, and the two inclined surfaces cooperate with the chamfers on the tray groove to form a positioning effect. The depth of the tray groove is greater than the height of the small tray, which creates excess space to avoid interference.
[0010] It is further defined that the small tray is provided with ribs on both sides along the length direction. Such a structural design makes it easier for the measurement personnel to hold the small tray when transferring the small tray, and is used to further locate the position of the small tray in the tray slot.
[0011] It is further defined that the pressure ring is provided with a threaded column, a pressure plate, and a torsion ring, the torsion ring is located at the upper end of the threaded column, the pressure plate is located at the circumference of the threaded column, the pressure ring is threadedly connected to the large pallet, the threaded column passes through the weight adjustment block, and the pressure plate presses the weight adjustment block. With such a structural design, the pressure plate fixes the weight adjustment block under the locking force of the threaded connection, and the torsion ring makes it easy for the measurement personnel to screw and lift the small pallet.
[0012] The beneficial effects of the utility model are as follows: sand and gravel aggregates of different particle sizes are placed in different small trays. When all the sand and gravel aggregates of all particle sizes are placed, the weight counting is started by taking away the small trays and the sand and gravel aggregates therein, thereby avoiding misreading and miscounting caused by placing sand and gravel aggregates while reading the weights. Moreover, sand and gravel aggregates of different particle sizes are stored separately, and the measurement personnel can read the weights repeatedly to confirm the accuracy of the readings, thereby avoiding the defects caused by mixing all the sand and gravel aggregates in sequence and reading the weights in increments.

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0026] like Figure 1-4 As shown, a quick quality detection device for sand and gravel aggregates of the utility model comprises an electronic scale body 1, a large tray 2 and a plurality of small trays 3;
[0027] The large pallet 2 is provided with a plurality of pallet slots 21 for placing small pallets 3. Both ends of the small pallet 3 in the length direction are connected to pressure rings 5. The pressure rings 5 press the weight adjustment block 4 onto the small pallet 3. The sum of the weights of the corresponding small pallet 3, pressure ring 5 and weight adjustment block 4 in each pallet slot 21 is a constant value.
[0028] In this embodiment:
[0029] The small tray 3 is first placed in the tray slot 21, and sand and gravel aggregates of different particle sizes are placed in different small trays 3. When all the sand and gravel aggregates of all particle sizes are placed, the weight counting is started to avoid misreading and miscounting caused by placing sand and gravel aggregates while reading;
[0030] Specifically, the sum of the weights of the small pallet 3, the pressure ring 5, and the weight adjustment block 4 corresponding to each pallet slot 21 is a fixed value, which is recorded as D. The function of the weight adjustment block 4 is to reduce the requirements for the weight consistency of the small pallet 3 and the pressure ring 5. According to the actual weight requirements, weight adjustment blocks 4 of different weights are selected to reduce the difficulty of satisfying the sum of the weights of the small pallet 3, the pressure ring 5, and the weight adjustment block 4 as a fixed value. First, after all the sand and gravel aggregates of all particle sizes are placed, the total weight is read out, and then only one small pallet 3 is taken out, the total weight decreases, and then the small pallet 3 that has been taken out is put back, and the total weight is restored to the original value. In this process, The measurement personnel obtain two values, one value is the total weight, recorded as G1, and the other value is the weight after taking away the small tray 3, recorded as G2. The size of G2 depends on the weight of the sand and gravel aggregate in the small tray 3. G1 minus G2 is equal to the sum of D and the weight of the sand and gravel aggregate in the small tray 3. Since D is a constant, the measurement personnel can know the weight of the corresponding sand and gravel aggregate in the small tray 3. The weight of the sand and gravel aggregate in the corresponding small tray 3 can be read out by taking out different small trays 3 separately in turn. In addition, sand and gravel aggregates of different particle sizes are stored separately. The measurement personnel can read the readings repeatedly to confirm the accuracy of the readings, avoiding the defects caused by mixing all the sand and gravel aggregates in turn and reading the weights in increments.
[0031] Preferably, a push button 6 is installed inside the tray slot 21. After the small tray 3 is placed in the tray slot 21, the push button 6 is triggered. Each push button 6 is connected to an LED light. The LED light has two lighting colors and is selected by the push button 6. With this structural design, when the small tray 3 is put in place for the first time, the push button 6 is triggered and the LED light shows red. When the small tray 3 is loaded with sand and gravel aggregates and is picked up and put down, the push button 6 is triggered for the second time, and the LED light shows green, indicating that the sand and gravel aggregates in the small tray 3 have been measured. In fact, other structural shapes for marking the measurement status can also be considered according to specific circumstances.
[0032] Preferably, the inner cavity of the small tray 3 is an isosceles trapezoid with a large top and a small bottom, and the outer surface of the small tray 3 is also an isosceles trapezoid. The depth of the tray slot 21 is greater than the height of the small tray 3, and the tray slot 21 is provided with a chamfer that matches the shape of the small tray 3. With such a structural design, the inner cavity of the small tray 3 is designed to be an isosceles trapezoid, which is convenient for putting in and taking out sand and gravel aggregates. The shape of the small tray 3 is also an isosceles trapezoid because the isosceles trapezoid has two inclined surfaces, and the two inclined surfaces cooperate with the chamfers on the tray slot 21 to form a positioning effect. The depth of the tray slot 21 is greater than the height of the small tray 3, which forms a space surplus to avoid interference. In fact, other structural shapes of the small tray 3 can also be considered according to specific circumstances.
[0033] Preferably, the small tray 3 is provided with ribs 31 on both sides along the length direction. With such a structural design, the ribs 31 are convenient for the measurement personnel to hold when transferring the small tray 3, and are used to further locate the position of the small tray 3 in the tray slot 21. In fact, other structural shapes of the small tray 3 can also be considered according to specific circumstances.
[0034] Preferably, the pressing ring 5 is provided with a threaded column 51, a pressing plate 52, and a torsion ring 53, wherein the torsion ring 53 is located at the upper end of the threaded column 51, the pressing plate 52 is located at the circumference of the threaded column 51, the pressing ring 5 is threadedly connected to the large tray 2, the threaded column 51 passes through the weight adjustment block 4, and the pressing plate 52 presses the weight adjustment block 4. With such a structural design, the pressing plate 52 fixes the weight adjustment block 4 under the locking force of the threaded connection, and the torsion ring 53 facilitates the measurement personnel to screw and lift the small tray 3. In fact, other structural shapes of the pressing ring 5 can also be considered according to specific circumstances.
[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
