In this embodiment, as shown in fig. 1, the rotary excavating device for building construction further includes a rotary excavator 200, the housing 121 is rotatably disposed on the rotary excavator 200, and the rotary excavator 200 is started to rotate the housing 121.
In this embodiment, when the second screw 131 moves downwards, the second one-way bearing 132 drives the baffle 123 to rotate.
The working process is as follows: in operation, the baffle 123 is rotated to open the discharge port, the second screw 131 is at the lowest position, the upper pressing plate 126 is at the lowest position, and the scraper 127 abuts against the bottom plate 122.
The rotary excavator 200 is started to rotate the housing 121, and the rotary tooth group 133 contacts with the soil to start rotary excavation. Soil can enter into in the shell 121 through the discharge gate when digging soon, and soil can begin to promote top board 126 after working a period and upwards move, and first spring is compressed this moment, and when top board 126 upwards moved, first screw rod 113 upwards moved, because first one-way bearing 114 is one-way bearing, first one-way bearing 114 rotated, and first one-way bearing 114 does not drive shell 121 and rotates, and top board 126 does not rotate this moment. The upper press plate 126 drives the first connecting rod 125 to move upwards when moving upwards, and after the upper press plate 126 moves upwards by a certain distance, the first connecting rod 125 and the second connecting rod 124 reach the maximum limit, that is, after the stop block in the first connecting rod 125 reaches the upper end of the vertical groove, the upper press plate 126 continues to move upwards to drive the second connecting rod 124 and the second screw 131 to move upwards. Because the second one-way bearing 132 is a one-way bearing, when the second screw 131 moves upward to drive the second one-way bearing 132 to rotate, the second one-way bearing 132 does not drive the baffle 123 to rotate, that is, when the second screw 131 moves upward, the discharge hole is still in an open state. The second screw 131 moves upward and the second spring is extended. After the upper press plate 126 rises to the highest, the second screw 131 reaches a stage without screw, at which time the baffle 123 closes the discharge hole under the push of the clods.
The device is moved to a soil unloading place, the trigger rod 115 is pressed downwards at the moment, the trigger rod 115 is in contact with the limiting plates 135, the two limiting plates 135 are gradually close to each other, the third spring is compressed, the limiting block 136 is driven to move towards the axis direction of the second connecting rod 124, the sleeve and the lantern ring are disconnected, and finally the second connecting rod 124 and the second screw 131 are disconnected. Under the effect of second spring, second screw 131 moves down and resets, and second screw 131 drives second one-way bearing 132 rotatory when moving down, and second one-way bearing 132 is rotatory to be driven the baffle 123 rotation and is opened the discharge gate. The first spring is gradually released and the upper press plate 126 moves downward, gradually pushing out the soil in the housing 121. When the upper platen 126 moves downward, the first screw 113 moves downward, the first one-way bearing 114 rotates, the first one-way bearing 114 and the housing 121 rotate together, and the upper platen 126 rotates. That is, the upper pressure plate 126 rotates while the upper pressure plate 126 moves downward, the scraper 127 is driven to rotate, the scraper 127 cleans the bottom plate 122, and the upper pressure plate 126 returns to the initial position. The sleeve is clamped on the sleeve ring, the trigger rod 115 is separated from the limiting plates 135 in contact, the two limiting plates 135 are away from each other again under the action of the third spring, and the limiting blocks 136 return to the initial positions to perform next rotary digging.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
