Description

Technical Field

[0001] The invention relates to the technical field of screening devices, and in particular to a sand screening device for urban planning and construction. Background Art

[0002] Urban planning is to regulate urban development and construction, study the future development of the city, the reasonable layout of the city and the comprehensive arrangement of various urban engineering construction projects. Screening devices are needed in the construction of buildings in urban planning, mainly to screen sand through screening devices.

[0003] As for the existing sand screening devices for urban planning and construction: 1. Although the existing device can achieve multiple high-efficiency screening during screening, it needs to use multiple driving elements when achieving multiple high-efficiency screening. Although this can achieve the purpose of improving the screening effect, it increases the equipment cost; 2. The driving components of the existing device tend to become hot after a period of screening, which will affect the life of the driving components. The most direct impact is that the service life of the driving components is reduced. Summary of the invention

[0004] In view of this, the present invention provides a sand screening device for urban planning and construction, which comprises a first auxiliary plate, a groove, a first protrusion, a screening part and a driving part.

The screening effect can be improved by the up and down reciprocating vibration screening, and the screening effect can be further improved through structural improvements while realizing the up and down reciprocating vibration screening, and while realizing the reciprocating screening, the airflow cooling of the driving motor can be realized through the structural improvements, thereby ensuring that the driving motor can work at a reasonable temperature and avoiding the driving motor being in a high temperature state for a long time, which leads to a shortened service life.

The two sliding rods are slidably connected to the two sliding blocks respectively, and each sliding rod is sleeved with an elastic member for resetting the sliding block backwards.

[0011] Furthermore, the collection box is located at a lower position of the screening frame, and the bottom end surface of the collection box is an arc-shaped structure.

[0012] Furthermore, two auxiliary blocks are symmetrically welded on the top surface of the collecting box, and both of the two auxiliary blocks are triangular prism-shaped structures.

[0015] Beneficial effects: 1. Through the arrangement of the first auxiliary plate, the groove, the first protrusion, the screening part and the driving part, first, because the top surfaces of the two first auxiliary plates are provided with grooves in a linear array, and the grooves are semi-cylindrical groove structures; two second protrusions are symmetrically welded on the bottom end surface of the screening frame, and the second protrusions are aligned with the grooves. When the sliding block slides back and forth, the second protrusions and the grooves are in a continuous clamping state. During use, the screening frame can be reciprocated up and down by the continuous clamping of the second protrusions and the grooves, and the vibration screening can be achieved by the up and down reciprocating motion of the screening frame, thereby improving the screening effect; Second, because the first protrusions are welded in a linear array on the two first auxiliary plates, the first protrusions are aligned with the second protrusions, and the first protrusions are semi-cylindrical structures, when the sliding block slides back and forth during use, the second protrusions are in a continuous clamping state with the first protrusions, thereby improving the screening effect; Third, because a second auxiliary plate is welded to the bottom end surface of the screening frame, a cooling hole is opened on the second auxiliary plate; the cooling hole is aligned with the position of the driving motor, the cooling hole is opened in an inclined shape, and the inclination angle of the cooling hole is 45 degrees. During use, when the screening frame reciprocates back and forth, the cooling hole is in the ejected airflow to achieve cooling of the driving motor.

[0016] Fourth, because two first auxiliary plates are symmetrically welded on the top of the base, the first auxiliary plates are located in the gap between the screening frame and the sliding seat. During use, the first auxiliary plates can prevent sand from entering the sliding seat and causing the sliding block to be blocked.

Through the setting of auxiliary grooves, because two auxiliary grooves are symmetrically opened on the top surface of the base, the two front fixing bolts are hidden in an auxiliary groove on the front side, and the two rear fixing bolts are hidden in an auxiliary groove on the rear side. When the four fixing bolts are tightened, the top end surface of the fixing bolt tail end is lower than the top end surface of the base. During use, the probability of the fixing bolt tail end being bumped can be reduced, preventing the fixing bolt tail end from being bumped and causing difficulty in disassembly.

[0018] 3. Through the setting of the collection part, first, because the collection box is located at the lower part of the screening frame, the bottom end surface of the collection box is an arc-shaped structure. During use, the sand sieved by the screening frame will fall into the collection box, and the sand falling into the collection box can be automatically collected and discharged; Second, because there are two auxiliary blocks symmetrically welded on the top of the collection box, both auxiliary blocks are triangular prism structures. The left and right end faces of the collection box are respectively in contact with the two first auxiliary plates.

Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0024] Example: Please refer to Figures 1 to 8 As shown: The present invention provides a sand screening device for urban planning and construction, comprising: a base 1, a screening part 2, a collecting part 3 and a driving part 4; The base 1 is fixedly connected to the screening table by four fixing bolts 101; The screening part 2 is composed of a sliding seat 201, a sliding block 202, a screening frame 203, a mounting seat 204, a sliding rod 205, an elastic member 206, a second auxiliary plate 207, a cooling hole 208 and a second protrusion 209. There are two sliding seats 201 in total, and the two sliding seats 201 are fixedly connected to the top surface of the base 1 by bolts; The collecting part 3 is composed of a collecting box 301 and an auxiliary block 302.

[0025] Among them, two auxiliary grooves 102 are symmetrically opened on the top surface of the base 1, the two front fixing bolts 101 are hidden in an auxiliary groove 102 on the front side, and the two rear fixing bolts 101 are hidden in an auxiliary groove 102 on the rear side. When the four fixing bolts 101 are tightened, the top end surface of the fixing bolt 101 is lower than the top end surface of the base 1. During use, the probability of the tail end of the fixing bolt 101 being bumped can be reduced, preventing the tail end of the fixing bolt 101 from being bumped and causing difficulty in disassembly.

[0026] Among them, each sliding seat 201 is slidably connected to a sliding block 202, and the two sliding blocks 202 are slidably connected to the screening frame 203. During use, when the two sliding blocks 202 slide back and forth at the same time, the screening frame 203 can be moved back and forth, and the screening action can be completed through the back and forth reciprocating movement of the screening frame 203.

[0027] Among them, two first auxiliary plates 103 are symmetrically welded on the top surface of the base 1. The first auxiliary plates 103 are located in the gap between the screening frame 203 and the sliding seat 201. During use, the first auxiliary plates 103 can prevent sand from entering the sliding seat 201 and causing the sliding of the sliding block 202 to be blocked.

[0028] The top surfaces of the two first auxiliary plates 103 are both provided with grooves 104 in a linear array, and the grooves 104 are semi-cylindrical groove structures; Two second protrusions 209 are symmetrically welded on the bottom surface of the screening frame 203, and the second protrusions 209 are aligned with the grooves 104. When the sliding block 202 slides back and forth, the second protrusions 209 and the grooves 104 are in a continuous clamping state. During use, the continuous clamping of the second protrusions 209 and the grooves 104 can realize the up and down reciprocating motion of the screening frame 203, and the up and down reciprocating motion of the screening frame 203 can realize vibration screening, thereby improving the screening effect.

[0029] Among them, the two first auxiliary plates 103 are welded with first protrusions 105 in a linear array. The first protrusions 105 are aligned with the second protrusions 209. The first protrusions 105 are semi-cylindrical structures. During use, when the sliding block 202 slides back and forth, the second protrusions 209 and the first protrusions 105 are in a continuous clamping state, thereby improving the screening effect.

[0030] Among them, there are two mounting seats 204, and a sliding rod 205 is welded to the rear end face of each mounting seat 204. The two sliding rods 205 are slidably connected to the two sliding blocks 202 respectively. Each sliding rod 205 is sleeved with an elastic member 206 for resetting the sliding block 202 backward. During use, the two elastic members 206 can realize automatic resetting of the sliding block 202.

[0031] Among them, the collection box 301 is located at the lower part of the screening frame 203, and the bottom end surface of the collection box 301 is an arc-shaped structure. During use, the sand particles sifted through the screening frame 203 will fall into the collection box 301, and the sand particles falling into the collection box 301 can be automatically collected and discharged.

[0032] Among them, two auxiliary blocks 302 are symmetrically welded on the top of the collection box 301. The two auxiliary blocks 302 are both triangular prism structures. The left end face and the right end face of the collection box 301 are respectively in contact with the two first auxiliary plates 103. During use, the sand can be reduced from falling into the gap between the collection box 301 and the first auxiliary plate 103, which will cause cumbersome subsequent cleaning.

[0033] Among them, a toggle block 402 is installed on the rotating shaft of the driving motor 401, and the toggle block 402 is located at the rear side of the screening frame 203. When the driving motor 401 rotates, the toggle block 402 elastically contacts the rear side of the screening frame 203. During use, the synchronous rotation of the toggle block 402 can be achieved through the rotation of the driving motor 401, and the screening frame 203 can be continuously squeezed by the rotation of the toggle block 402, thereby finally realizing the forward and backward movement of the screening frame 203.

[0034] The bottom end surface of the screening frame 203 is welded with a second auxiliary plate 207, and a cooling hole 208 is opened on the second auxiliary plate 207; The cooling hole 208 is aligned with the driving motor 401 and is opened in an inclined shape with an inclination angle of 45 degrees. During use, when the screening frame 203 reciprocates back and forth, the cooling hole 208 is in the ejected airflow to achieve cooling of the driving motor 401.

[0035] The specific usage and function of this embodiment are as follows: When in use, first pour the sand to be screened into the screening frame 203, and then start the driving motor 401. When the driving motor 401 rotates, the synchronous rotation of the toggle block 402 can be achieved through the rotation of the driving motor 401, and the screening frame 203 can be continuously squeezed through the rotation of the toggle block 402. At this time, the screening frame 203 can be continuously reset under the action of the elastic member 206, and finally the forward and backward movement of the screening frame 203 is achieved, and the screening action can be completed through the screening frame 203; At the same time, because the top surfaces of the two first auxiliary plates 103 are both provided with grooves 104 in a linear array, and the grooves 104 are of a semi-cylindrical groove structure; two second protrusions 209 are symmetrically welded on the bottom surface of the screening frame 203, and the second protrusions 209 are aligned with the grooves 104. When the sliding block 202 slides back and forth, the second protrusions 209 and the grooves 104 are in a continuous clamping state. During use, the continuous clamping of the second protrusions 209 and the grooves 104 can realize the up and down reciprocating motion of the screening frame 203, and the up and down reciprocating motion of the screening frame 203 can realize vibration screening, thereby improving the screening effect; and because the first protrusions 105 are both welded on the two first auxiliary plates 103 in a linear array, the first protrusions 105 and the second protrusions 209 are aligned, and the first protrusions 105 are of a semi-cylindrical structure. During use, when the sliding block 202 slides back and forth, the second protrusions 209 and the first protrusions 105 are in a continuous clamping state, thereby improving the screening effect; At the same time, since the second auxiliary plate 207 is welded to the bottom end surface of the screening frame 203, a cooling hole 208 is opened on the second auxiliary plate 207; the cooling hole 208 is aligned with the driving motor 401, and the cooling hole 208 is opened in an inclined shape, and the inclination angle of the cooling hole 208 is 45 degrees. During use, when the screening frame 203 reciprocates back and forth, the cooling hole 208 is in the ejected airflow to achieve cooling of the driving motor 401; At the same time, the screened sand will fall into the collection box 301. At this time, because the collection box 301 is located at the lower protection position of the screening frame 203, the bottom end surface of the collection box 301 is an arc-shaped structure. During use, the sand screened by the screening frame 203 will fall into the collection box 301, and the sand falling into the collection box 301 can be automatically collected and discharged; During use, two first auxiliary plates 103 are symmetrically welded on the top of the base 1, and the first auxiliary plates 103 are located in the gap between the screening frame 203 and the sliding seat 201. During use, the first auxiliary plates 103 can block the sand from entering the sliding seat 201, which will cause the sliding of the sliding block 202 to be blocked; and because two auxiliary blocks 302 are symmetrically welded on the top of the collection box 301, both of which are triangular prism-shaped structures, the left end face and the right end face of the collection box 301 are in contact with the two first auxiliary plates 103 respectively, which can reduce the sand from falling during use. It falls into the gap between the collection box 301 and the first auxiliary plate 103, which makes subsequent cleaning complicated; and because two auxiliary grooves 102 are symmetrically provided on the top surface of the base 1, the two front fixing bolts 101 are hidden in the front auxiliary groove 102, and the two rear fixing bolts 101 are hidden in the rear auxiliary groove 102. When the four fixing bolts 101 are tightened, the top end surface of the tail end of the fixing bolt 101 is lower than the top end surface of the base 1. During use, the probability of the tail end of the fixing bolt 101 being bumped can be reduced, thereby preventing the tail end of the fixing bolt 101 from being bumped and causing difficulty in disassembly.

[0036] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
