Detailed Description

The present application is described in further detail below with reference to figures 1-6.

The embodiment of the application discloses an automatic weighing device that weighs. Referring to fig. 1, the weighing apparatus includes a weighbridge 1 and slopes 2 cast by concrete on both ends of the weighbridge 1 in a longitudinal direction, and the upper ends of the slopes 2 have flat portions flush with the upper surface of the weighbridge 1. An empty groove 3 is reserved between the wagon balance 1 and the side slope 2. A storage groove 4 detachably connected with the side slope 2 is arranged in the empty groove 3.

Referring to fig. 1, the support frames 5 are installed at two ends of the wagon balance 1 in the width direction, and each support frame 5 comprises two vertically arranged support plates 51 and a transverse plate 52 welded and fixed between the two support plates 51. The support plate 51 is fixedly mounted on the side wall of the side slope 2 by bolts. A cleaning component 6 is arranged between the two support frames 5, and the cleaning component 6 comprises a scraper 61 and connecting pieces connected to two ends of the scraper 61. The support frame 5 is provided with a driving assembly 7 for driving the connecting piece to move along the length direction of the wagon balance 1. Before the vehicle weighs, drive assembly 7 drives the connecting piece removal of both sides, and then makes scraper blade 61 stir the rubble debris of weighbridge 1 upper surface to the storage tank 4 in, reduces the tire and rolls the condition that the rubble caused the splash and take place.

Referring to fig. 2, the driving assembly 7 includes a screw 71 and a synchronous motor 72 with a forward and reverse rotation function. The screw rod 71 is horizontally arranged, one end of the screw rod is rotatably arranged on one support plate 51 through a bearing, the other pipe is rotatably arranged on the other support plate 51 through a bearing, and the screw rod penetrates through the support plate 51 to be connected with the synchronous motor 72 through a key; the synchronous motors 72 are fixedly mounted on the support plate 51 through bolts, and the two synchronous motors 72 are located on the same side of the two support frames 5.

Referring to fig. 2 and 3, the connection member includes a connection block 62. The connecting block 62 is sleeved on the screw 71 and is in threaded connection with the screw. The lower surface of the connecting block 62 is engaged with the upper surface of the transverse plate 52, so that the screw 71 can stably drive the connecting block 62 to move along the axis of the screw 71. The synchronous motors 72 on both sides are started simultaneously to drive the connecting blocks 62 on both sides to synchronously move towards the same direction, and further drive the scraper 61 to scrape impurities such as broken stones on the upper surface of the wagon balance 1.

Referring to fig. 3 and 4, the end of the blade 61 is slidably attached to the connecting member in the vertical direction. Scraper blade 61 tip an organic whole is connected with the grafting post, and the up end of grafting post flushes with scraper blade 61 up end. A lifting groove 621 is formed on a side wall opposite to the two connecting blocks 62. The inserting column is inserted into the lifting groove 621 and forms a sliding connection relationship with the lifting groove 621 along a vertical direction. The sidewall of the plug column close to the support plate 51 is always attached to the wall of the lifting groove 621, so that the scraper 61 does not rotate and shift when the connecting block 62 moves.

Referring to fig. 4, an elastic member is installed in the lifting groove 621, and the elastic member may be a biasing spring 622. One end of the abutting spring 622 is welded and fixed on the scraper 61, and the other end is welded and fixed on the groove wall of the lifting groove 621 far away from the ground. The biasing spring 622 is always in a compressed state, so that the scraper 61 is always driven to move downward.

Referring to fig. 2 and 3, an abutment plate 53 is welded to one side wall of the transverse plate 52 adjacent to the wagon balance 1. The bottom of one end of the scraper 61 close to the inserting column is welded with an abutting block 612. The abutting block 612 always abuts against the abutting plate 53. The end of the abutting plate 53 near the support plate 51 is provided with an inclined surface 531, and the inclined surface 531 is provided obliquely upward from the end of the abutting plate 53 toward the center of the abutting plate 53.

Referring to fig. 2 and 3, when the abutment block 612 is moved to the inclined surface 531 along the length direction of the abutment block 612 by the pushing of the connecting block 62, the scraper 61 is positioned above the storage groove 4. The abutting spring 622 pushes the plug column to descend along the lifting groove 621; the vertical height of the abutment block 612 descending along the inclined surface 531 is greater than the height of the scraper 61 in the vertical direction; therefore, the scraper 61 can be lowered into the storage tank 4, and the highest point of the scraper 61 is lower than the upper surface of the wagon balance 1, so that the damage to the scraper 61 caused by the fact that the tire directly rolls on the scraper 61 is avoided.

Referring to fig. 3 and 4, rollers 613 are mounted at both ends of the bottom of the abutment block 612 in the longitudinal direction of the abutment plate 53 in order to allow the abutment block 612 to smoothly move along the inclined surface 531.

Referring to fig. 5 and 6, in order to facilitate cleaning of the storage tank 4 for removing debris, a sliding bar 41 is provided along the length direction of the storage tank 4 on a side wall of the storage tank 4 close to the side slope 2. The side wall of the slope 2 is correspondingly provided with a sliding groove 21 for inserting the sliding strip 41. The width of the notch at one side of the sliding groove 21 close to the storage groove 4 is smaller than that of the groove wall far away from the storage groove 4, and the whole sliding groove is of a dovetail groove structure. The sliding bar 41 is matched with the sliding bar, so that the stability is improved.

Referring to fig. 5 and 6, one side of the sliding groove 21 in the length direction is a closed structure so that the sliding bar 41 abuts against the groove wall after sliding. And a locking bolt 22 is connected to the outer wall of the closed end of the side slope 2 away from the sliding groove 21 in a threaded manner. The axial direction of the lock bolt 22 is the same as the longitudinal direction of the slide groove 21. A stop lever 23 is vertically welded at the bolt head of the locking bolt 22. The locking bolt 22 is rotated to abut the stop lever 23 against the outer wall of the storage compartment 4, thereby restricting it from sliding out of the sliding slot 21.

The implementation principle of the automatic weighing device that weighs of this application embodiment does:

when the vehicle does not enter the wagon balance 1 during the cleaning of the detritus, the two synchronous motors 72 are started to drive the screw rod 71 to rotate, and the connecting block 62 moves along the axis of the screw rod 71, so that the abutting block 612 rises along the inclined surface 531 and drives the scraper 61 to rise; when the lower surface of the scraper 61 rises to be flush with the upper surface of the wagon balance 1; the link block 62 continues to move and the scraper 61 scrapes the crushed stone on the surface of the weighbridge 1 into the storage tank 4, and simultaneously the scraper 61 descends into the storage tank 4. When another vehicle is about to pass through the pound after the vehicle passes by, the two synchronous motors 72 rotate reversely to drive the scraping plates 61 to fold back to scrape broken stones. The reciprocating operation can effectively reduce the splashing condition caused by the rolling of sundries such as broken stones by tires.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
