Description

Technical Field

[0001] The utility model relates to the technical field of silt removal equipment, in particular to a foundation pit silt removal device for building construction. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Due to rainwater sedimentation or groundwater infiltration, a large amount of silt will be generated in the foundation pit. During house construction, a silt suction truck is needed to clean the silt in the foundation pit. The silt suction pipe connected to the tank of the silt suction truck is placed in the foundation pit, and the silt suction truck sucks the silt into the tank through the silt suction pipe.

[0003] A Chinese patent discloses a foundation pit desilting device for construction (patent number: CN219298300U). The technical solution drives the third bevel gear to rotate by a driving motor, so that the third bevel gear drives the first bevel gear and the second bevel gear to rotate, so that the transmission pipe and the transmission shaft can rotate in positive and negative directions respectively, so that the transmission pipe and the transmission shaft respectively drive the first cutter and the second cutter to rotate through the first scraper and the second scraper, so that the first cutter and the second cutter cut off the impurities such as branches blocked on the surface of the filter screen, so as to avoid the impurities blocking the filter screen and affecting the silt suction effect of the silt suction pipe. However, the scheme still has shortcomings. When the first cutter and the second cutter cut the branches, the places that the blades can cut are not wide enough, and they are mainly concentrated on the edge of the filter screen, which is relatively one-sided. Moreover, the length of the branches after cutting may still be relatively long or the volume is large, and they may still be stuck in the filter screen when passing through the filter screen. There may also be some stones that cannot be cut and are also stuck on the filter screen, which is troublesome to clean up, which may affect the subsequent desilting and reduce efficiency.

[0022] See also Figure 1-4 The utility model provides a technical solution of a foundation pit desilting device for construction. The utility model will be further described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] A foundation pit desilting device for construction includes a desilting vehicle 1, a desilting box 2 is arranged on the top of the desilting vehicle 1, a silt suction pipe 3 is fixedly connected to the right side of the desilting box 2, a filter 4 is threadedly connected to the right end of the silt suction pipe 3, and a first fixing plate 5 is arranged on the left outer wall of the filter 4. A first blade 6 is fixedly connected to the upper and lower outer walls of the first fixing plate 5, and a scraper 7 is arranged on the right side of the first blade 6. A second fixing plate 8 is arranged on the left side of the first fixing plate 5, and a second blade 9 is arranged on the left and right outer walls of the second fixing plate 8. A driving mechanism is arranged in the inner cavity of the silt suction pipe 3, a fixing ring 10 is fixedly connected to the outer wall of the silt suction pipe 3, and a component box 11 is fixedly connected to the upper part of the fixing ring 10, an air pump 12 is arranged on the left side of the inner cavity of the component box 11, and an air pipe 13 is arranged at the lower end of the air pump 12, an electromagnetic valve 14 is arranged in the inner cavity of the silt suction pipe 3, and an electromagnetic component 15 is arranged in the inner cavity of the component box 11.

[0025] Specifically, the first blade 6 and the second blade 9 are right-angled triangle structures, and the right-angled sides are on the same vertical plane.

[0026] Furthermore, the length of the first fixing plate 5 and the second fixing plate 8 is greater than the diameter of the filter 4, the right wall of the first fixing plate 5 is fixedly connected to the left end of the transmission cylinder 16, the right wall of the second fixing plate 8 is fixedly connected to the left end of the transmission rod 17, and the lower end of the air pipe 13 is arranged on the left side of the electromagnetic valve 14, and the lower end of the air pipe 13 is inclined toward the side close to the filter 4.

[0027] When used specifically, Figure 1 , Figure 2 and Figure 3 , Figure 4 As shown, when silting is performed, the drive motors 21 on the transmission cylinder 16 and the transmission rod 17 can be started respectively to drive the first fixed plate 5 and the second fixed plate 8 connected thereto to rotate. Since the drive motor 21 itself can choose to rotate forward or reverse, the first fixed plate 5 and the second fixed plate 8 can be rotated in the opposite direction, and the first blade 6 and the second blade 9 thereon can be further driven to rotate, thereby cutting impurities such as branches passing through the filter 4 or stuck on the filter 4, and at the same time, the scraper 7 will also clean its surface to avoid clogging the filter 4. Since the inner cavity of the filter 4 and the outer wall of the inlet end of the silt suction pipe 3 are threadedly connected, when the filter 4 needs to be replaced or cleaned, it can be disassembled and installed more quickly, which is convenient for subsequent use, saving time and improving efficiency.

[0028] Embodiment 2:

[0029] On the basis of the first embodiment, a foundation pit desilting device for construction is provided, wherein the driving mechanism includes a transmission cylinder 16, the inner cavity of the transmission cylinder 16 is provided with a transmission rod 17, the rotating rod 17 is rotatably connected to the inner cavity of the transmission cylinder 16, one end of the transmission cylinder 16 and the transmission rod 17 are provided with a driven gear 18, the side of the driven gear 18 is meshedly connected with a driving gear 19, a rotating shaft 20 is provided on the right side of the driving gear 19, and a driving motor 21 is provided at one end of the rotating shaft 20.

[0030] Specifically, the electromagnetic assembly 15 includes an electromagnetic coil, an iron core, a valve body, a valve core and a spring, and each structure is electrically connected through wires. The electromagnetic assembly 15 and the electromagnetic valve 14 are both prior arts and will not be described in detail here. The transmission rod 17 and the movable sleeve are connected to the inner cavity of the transmission cylinder 16, and the length of the transmission rod 17 is greater than that of the transmission cylinder 16, and the right end of the transmission rod 17 is also provided with a driven gear 18, a driving gear 19, a rotating shaft 20 and a driving motor 21.

[0031] When used specifically, Figure 3 and Figure 4 As shown, when silting, it is necessary to start two drive motors 21 at the same time, and the rotation directions of the two drive motors 21 are opposite, so that the driving gear 19 connected thereto can be used to drive the driven gear 18 to rotate, thereby driving the transmission cylinder 16 and the transmission rod 17 respectively connected thereto to rotate one forward and one reverse, thereby driving the first fixed plate 5 and the second fixed plate 8 at the front of the silt suction pipe 3 to rotate in the opposite direction, and then driving the first blade 6 and the second blade 9 to rotate to achieve cutting, which is not easy to get stuck. However, even when silting, when cutting impurities such as branches, there may still be a problem of impurities clogging the filter 4. At this time, the silt suction can be stopped, and the electromagnetic component 15 is used to energize the electromagnetic coil and the iron core, so that the electromagnetic coil generates electromagnetic, and the electromagnetic valve 14 is opened. Then, the air pump 12 is opened, and the air pipe 13 is used to inflate it. The internal air pressure increases, and the gas will overflow outward, acting on the filter 4 in the reverse direction, thereby ejecting the impurities stuck thereon, avoiding clogging the filter 4, and it can be quickly and directly cleaned in a relatively simple and efficient manner, reducing the impact on subsequent use.
