Problems solved by technology

[0007] However, this technical solution also has the following technical problems: First, the technical solution uses the crushing rod to rotate in the crushing stage and utilizes the crushing blade on the crushing rod to collide with the raw material for crushing. The extrusion effect cannot be produced, resulting in low crushing efficiency; secondly, because the raw materials are accumulated on the screen, on the one hand, there needs to be a height difference between the screen and the crushing rod, and this height difference leads to a high degree of raw material crushing unevenness at the bottom , together with the raw materials stuck in the mesh of the screen, it is easy to block the screen, resulting in stuck holes, affecting the normal sieving of raw materials, and excessive accumulation of raw materials for a long time, easy to cause excessive extrusion deformation of the screen, another On the one hand, the screen mesh is a hollow structure, and its own load-bearing load is insufficient, resulting in the restriction of a single crushing capacity; thirdly, due to the large amount of concrete raw materials, in order to improve the uniformity of its mixing, various raw materials are input in multiple batches, each Mixing method with a small amount of input in batches
In this technical solution, the combination of the crushing device and the crushing device only uses the screen as the intermediate transition layer, and the crushed raw materials will fall into the mixing device at any time, and the range of various raw materials falling into the mixing device per unit time is not easy to control , affecting the mixing uniformity of raw materials

Embodiment 1

[0073] Such as figure 1 As shown, this embodiment discloses a raw material crushing and mixing device for processing prestressed concrete pipe piles, which includes a crushing device 1 and a mixing device 2 in sequence according to the process from first to last.

[0074] Such as Figure 2-5 As shown, the crushing device 1 includes an upper crushing member 11 , a lower pressing mechanism 12 , a supporting blanking member 13 , a lower material screen 14 , a pushing mechanism 15 , and a one-way rotation mechanism 16 . The upper crushing part 11 is located above the supporting blanking part 13, and the downward movement of the pressing mechanism 12 can drive the upper crushing part 11 to move downward.

[0075] A cyclic movement of the pressing mechanism 12 includes a single downward pressing movement stage, a reciprocating pressing movement stage, and a one-way rising and returning movement stage. In the stage of single downward pressure movement, the downward pressure movemen...

Embodiment 2

[0117] Such as Figure 4 As shown, the difference between this embodiment and the above-mentioned embodiments is that an upper protrusion 111 is provided on the bottom surface of the upper crushing member 11 , the tip of the upper protrusion 111 is downward, and a plurality of upper protrusions 111 are distributed in a matrix. A lower protrusion 1311 is disposed on the top surface of the lower support plate 131 , the tip of the lower protrusion 1311 is upward, and a plurality of lower protrusions 1311 are distributed in a matrix.

[0118] Since a plurality of upper protrusions 111 and lower protrusions 1311 are respectively arranged on the upper crushing part 11 and the lower support plate 131, the pressure for extruding the raw materials on the lower support plate 131 is increased, and the crushing force is improved.

[0119] The upper protrusion 111 and the lower protrusion 1311 also have a conical structure or a circular truncated structure.

[0120] Further, the projectio...

Embodiment 3

[0122] Such as Figure 18 , 23 , 24, the difference between this embodiment and the above-mentioned embodiment is that the middle of the installation frame 132 is hollowed out, and the side is provided with guide holes 13211, the main part of the lower support plate 131 is built in the middle hollow of the installation frame 132, the lower support plate 131 A part of the side protrudes from the corresponding guide hole 13211 . When the lower support plate 131 is horizontal, the bottom surface of a part of its side contacts with the inner bottom surface of the guide hole 13211 . The first rotating shaft 1841 is fixed to the installation frame 132 .

[0123] Further, part of the side of the lower support plate 131 can move up and down along the guide hole 13211, and the third cam shaft 1391 is also rotated on the mounting frame 132, and the third cam shaft 1391 is fixed with the third cam 1392 and the third cam shaft 1391. A transmission bevel gear 1393, the transition shaft ...

Abstract

The invention discloses a crushing device. According to the crushing device, in the one-way downward pressing motion stage, a supporting material falling part rotates to be in a horizontal state, and a pushing plate of a pushing mechanism is made to move to the starting end of a discharging mesh screen; in the reciprocating downward pressing motion stage, raw materials on the horizontal supporting material falling part are extruded and crushed, and a one-way rotating mechanism moves to enable a lower supporting plate in a linkage supporting material falling part to move; and in the one-way rising reset motion stage, the supporting material falling part rotates to be inclined, so that a material pushing plate of a material pushing mechanism moves to the tail end of the discharging mesh screen and drives a screen body in the discharging mesh screen to shake. The invention further discloses a raw material crushing and mixing device for prestressed concrete pipe pile machining. The raw material crushing and mixing device has the beneficial effects that the crushing efficiency and the crushing quality of the crushing device are improved, and it is guaranteed that crushed raw materials are accurately discharged in time, and operation and control are convenient and fast.

Description

technical field [0001] The invention relates to the technical field of pipe pile concrete processing, in particular to a raw material crushing and mixing device for processing prestressed concrete pipe piles. Background technique [0002] Pipe piles are divided into prestressed concrete pipe piles and prestressed high-strength concrete pipe piles according to the concrete strength grade or effective precompression stress. The prestressed concrete pipe pile is code-named PC, the prestressed high-strength concrete pipe pile is code-named PHC, and the thin-walled pipe pile is code-named PTC. The concrete strength of PC piles shall not be lower than C60, the strength grade of thin-walled pipe piles shall not be lower than C60, and the concrete strength grade of PHC piles shall not be lower than C80. [0003] Concrete needs to be mixed and configured before being poured into the formwork. The concrete in the prior art is usually configured according to the type of its raw materi...
