Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: as shown in fig. 1-2, a layered weighing gravel sieve device comprises a vibration base 1, wherein a support is arranged on the vibration base 1, a plurality of layers of square-hole gravel sieves 2 are arranged on the support, the open ends of the square-hole gravel sieves 2 face upwards, and the sieve pore ends face downwards. The support comprises a bottom plate 3 and two vertical plates 4, the bottom plate 3 is installed on the vibration base 1, the two vertical plates 4 are vertically arranged on two opposite sides of the upper side of the bottom plate 3, the bottom plate 3 and the vertical plates 4 can vibrate up and down under the action of the vibration base 1, and therefore materials in the square hole gravel sieve 2 can be screened and separated.

A plurality of sliding grooves 5 are formed in the vertical plate 4, the length direction of each sliding groove 5 is consistent with the width direction of the vertical plate 4, and the sliding grooves are distributed in parallel along the vertical direction of the vertical plate 4; one end of the sliding chute 5 is positioned in the middle of the vertical plate 4, and the other end of the sliding chute extends and penetrates through one side edge of the vertical plate 4, so that the sliding chute 5 is provided with an opening end and a closed end; be equipped with spacing groove 6 at the downside that spout 5 is close to the blind end, spacing groove 6 semicircular in shape, and the vertical holding tank that has seted up downwards of tank bottom of spacing groove 6 holding weighing sensor 7 has been held in the holding tank, weighing sensor 7's sense terminal sets up to protrusion in the holding tank.

Supporting rods 8 are arranged on two opposite sides of the square hole gravel screen 2, and the supporting rods 8 can slide along the sliding grooves 5 and fall into the limiting grooves 6 to abut against the detection ends of the weighing sensors 7; the weight of the square hole sieve can be detected through the weighing sensor.

Gaps are reserved between the adjacent square hole sand screens 2.

During the specific use, through clamp erection bracing pole 8 on every square hole grit sieve 2, push spout 5 with 8 levels of bracing piece after the completion, final bracing piece 8 slides the blind end of spout and falls into spacing groove 6, and at this moment, the downside of bracing piece 8 supports to press on the detection of weighing sensor 7 in the holding tank holds, and weighing sensor 7 independently weighs to this layer of grit sieve. Put into a plurality of square hole grit sieves 2 in proper order, place and start vibration base 1 after accomplishing, vibration base 1 vibrates the grit sieve on its upper portion through bottom plate 3 and riser 4, sieves the grit, and the screening is accomplished the back, and the vertical that weighing sensor 7 at each layer shows is the weight at each layer promptly. In order to ensure that the layers are independent, gaps are reserved between the adjacent square hole sand and stone sieves 2, and weighing is more accurate.

The square hole grit sieve 2 goes up the cover and is equipped with spacing cover 9, spacing cover 9 links to each other with square hole grit sieve 2 sliding fit, has seted up the hole of stepping down corresponding to the position of bracing piece on spacing cover. Considering that a gap is formed between adjacent square hole sand and stone sieves 2, in the process of vibration screening, a lot of dust can be generated to diffuse from the gap, meanwhile, all layers of the square hole sand and stone sieves 2 are not supported, under the supporting action of the supporting rods 8, the square hole sand and stone sieves 2 can be overturned easily, the use is influenced, and meanwhile, the weight of each component after final screening is influenced by the diffusion of the dust, therefore, a limiting cover 9 is sleeved on the periphery of the square hole sand and stone sieve 2, strip-shaped abdicating holes are arranged on the side wall of the limiting cover 9 right opposite to the supporting rods 8, the limiting cover 9 can be buckled down by the square hole sand and stone sieve 2 on the uppermost layer until the bottom end of the limiting cover 9 is supported on the bottom plate 3, and the limiting cover 9 is connected with the outer wall of the square hole sand and stone sieve 2 in a sliding fit manner, therefore, the limiting function of preventing the square hole sand and stone sieves 2 from overturning is realized while the vertical vibration of, and also has a dust-proof function.

The weighing device is characterized by further comprising a display screen, wherein the display screen is connected with the weighing sensor 7 and used for displaying a collecting signal of the weighing sensor. Thus, the weight of each layer component can be displayed more visually, and recording and statistics are facilitated.

In embodiment 2, as shown in fig. 3 to 4, different from embodiment 1, a plurality of layers of limiting covers 9 are sleeved on the square-hole sand screen 2, and the limiting covers 9 are fixedly sleeved outside the open ends of the square-hole sand screen 2 and extend upwards, so that the limiting covers 9 can be slidably sleeved outside the screen hole ends of the upper adjacent square-hole sand screen 2. Considering that the limiting cover 9 in the embodiment 1 has the receding holes on two sides and the receding holes are in a strip structure, so that a certain gap still exists at the receding holes after the limiting cover 9 is buckled down, and some dust still diffuses out, therefore, in order to better seal the gap of the square hole sand and stone screen 2, the limiting cover 9 shown in fig. 3 is adopted, the lower end of the limiting cover 9 is fixedly connected to the outer side of the open end of the lower square hole sand and stone screen 2, the upper end of the limiting cover is connected to the outer side of the screen hole end of the upper square hole sand and stone screen 2 in a sliding fit manner, and the superposition height of the limiting cover 9 and the square hole sand and stone screen 2 is smaller than the height of the lower side of the supporting rod 8 on the square hole sand and stone screen 2, so that the square hole sand and stone screen 2 can still freely vibrate up and down during vibration, and the gap between layers has a good sealing effect, thereby preventing the diffusion of the, simultaneously also can be better prevent the upset of square hole grit sieve 2.

According to the scheme, the plurality of layers of sand and stone sieves are independently arranged, and each layer of sand and stone sieve is provided with the weighing sensor, so that layered weighing of the sand and stone sieves is realized; and in order to improve the degree of accuracy of weighing, be provided with the clearance between each layer, prevent the interference between the layer, dustproof and spacing processing are carried out to the clearance between the layer simultaneously, and it is effectual to weigh, and the accuracy is high, the simple operation.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and those skilled in the art should understand that those modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all should be covered in the scope of the claims of the present invention.
