DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0026] like Figure 1-Figure 7 As shown, an embodiment of an anti-blocking bidirectional cement mixing pile is provided in this embodiment. An anti-blocking bidirectional cement mixing pile comprises a mixing pile body 1 and a plurality of drill bits 2. The mixing pile body 1 is provided with an extrusion structure 3. The extrusion structure 3 comprises a push plate 4 movably mounted inside the mixing pile body 1. The push plate 4 is provided with a cement inlet 5. The inner side of the cement inlet 5 is provided with a plurality of grooves. Springs 6 are installed in the plurality of grooves. A clamping plate 7 is installed at one end of the spring 6. The push plate 4 is provided with a plurality of electric telescopic rods 8. Through the arrangement of the extrusion structure 3, the cement blocked inside the mixing pile body 1 can be cleaned. When the cement is blocked inside the mixing pile body 1, the plurality of electric telescopic rods 8 are started to drive the push plate 4 to press downward to push the cement stuck on the inner wall, and the cement blocked on the mixing pile body 1 is cleared. When pouring cement, the delivery pipe is delivered to the inside of the mixing pile body 1 through the cement inlet 5. The clamping plate 7 clamps the delivery pipe under the action of the plurality of springs 6 to play a fixing role.
[0027] A plurality of bearings 9 are installed on the push plate 4, a sleeve 10 is installed on the bearing 9, a first bolt 11 is installed on the output end of the electric telescopic rod 8, and the sleeve 10 and the first bolt 11 are threadedly connected. Through the arrangement of the bearing 9, the sleeve 10 and the first bolt 11, the sleeve 10 can be separated from the first bolt 11 by rotating, so that the push plate 4 can be disassembled from the electric telescopic rod 8 conveniently, and the cement stuck to the bottom of the push plate 4 can be cleaned.
[0028] A plurality of drill teeth 12 are installed at the bottom of the mixing pile body 1. Through the arrangement of the drill teeth 12, when the mixing pile body 1 drills downward and encounters harder soil or stones, the drill teeth 12 can drill and crush them more easily, thus saving time.
[0029] A plurality of rake teeth 13 are installed on the drill bit 2. The arrangement of the rake teeth 13 can more fully cut the soil and make it easier for the mixing pile body 1 to drill downwards.
[0030] A plurality of fixing plates 14 are installed on the outside of the mixing pile body 1, and the plurality of fixing plates 14 are connected with each other by second bolts 15. By setting the fixing plates 14 and the second bolts 15, the mixing pile body 1 can be fixed to prevent shaking during mixing, which may cause the pile hole to be non-vertical.
[0031] A plurality of balls 16 that fit the stirring pile body 1 are movably mounted on the fixed plate 14. The arrangement of the balls 16 reduces the friction between the stirring pile body 1 and the fixed plate 14, so that the stirring pile body 1 is not restricted when rotating.
[0032] The second bolt 15 is provided with an anti-skid pattern 17 . The anti-skid pattern 17 increases the friction force on the surface of the second bolt 15 , making it easier for the cement inlet 5 to rotate.
[0033] In this embodiment, if Figure 1-Figure 7 As shown, the working process of an anti-blocking bidirectional cement mixing pile provided in this embodiment is as follows:
[0034] When cement is blocked inside the mixing pile body 1, multiple electric telescopic rods 8 are started to drive the push plate 4 to press downward to push the cement stuck on the inner wall, so as to clear the cement blocked on the mixing pile body 1. When pouring cement, the delivery pipe is delivered to the inside of the mixing pile body 1 through the cement inlet 5. The clamping plate 7 clamps the delivery pipe under the action of multiple springs 6 to fix it. The rotating sleeve 10 can be separated from the first bolt 11, so that the push plate 4 can be removed from the electric telescopic rod 8 conveniently, and the cement stuck to the bottom of the push plate 4 can be cleaned. When encountering harder soil or stones during downward drilling, the drill teeth 12 can drill and crush them more easily, saving time. The rake teeth 13 can cut the soil more fully, making it easier for the mixing pile body 1 to drill downward. The fixing plate 14 and the second bolt 15 can fix the mixing pile body 1 to prevent shaking during mixing, which may cause the pile hole to be non-vertical. The ball 16 reduces the friction between the mixing pile body 1 and the fixing plate 14, so that the mixing pile body 1 is not restricted when rotating. The anti-skid pattern 17 increases the friction on the surface of the second bolt 15, making it easier for the cement inlet 5 to rotate.
[0035] In summary, in this embodiment, according to an anti-blocking bidirectional cement mixing pile of this embodiment, through the arrangement of the bearing 9, the sleeve 10 and the first bolt 11, the rotating sleeve 10 can be separated from the first bolt 11, so that the push plate 4 is convenient to be disassembled from the electric telescopic rod 8, and the cement stuck to the bottom of the push plate 4 is cleaned. Through the arrangement of the drill teeth 12, when the mixing pile body 1 drills downward and encounters harder soil or stones, the drill teeth 12 can drill and crush them more easily, saving time. Through the arrangement of the rake teeth 13, the soil can be cut more fully, making it easier for the mixing pile body 1 to drill downward. Through the arrangement of the fixed plate 14 and the second bolt 15, the mixing pile body 1 can be fixed to prevent shaking during mixing, which causes the pile hole to be non-vertical. Through the arrangement of the ball 16, the friction between the mixing pile body 1 and the fixed plate 14 is reduced, so that the mixing pile body 1 is not restricted when rotating. Through the arrangement of the anti-slip pattern 17, the friction on the surface of the second bolt 15 is increased, so that the cement inlet 5 is easier to rotate.
