DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] See also Figure 1 - Figure 6 The present application provides a stone crushing equipment for bridge engineering construction, comprising:

[0036] A rolling box 100 is provided with a frame 102 at the bottom of the rolling box 100, a rolling roller 103 for rolling the crushed stone is horizontally arranged inside the rolling box 100, a connecting shaft 104 is vertically arranged in the middle of the rolling roller 103, a driving mechanism is arranged inside the rolling box 100, the driving mechanism is connected to the connecting shaft 104, and can drive the connecting shaft 104 and the rolling roller 103 to rotate and roll the crushed stone, and the driving mechanism is an existing gear transmission mechanism, which will not be described in detail here;

[0037] A roller frame 106 is sleeved on the rolling roller 103, and both ends of the roller frame 106 are provided with a material shifting and turning mechanism 200, which shifts the crushed stone particles on the edge of the rolling roller 103 inward. By providing the material shifting and turning mechanism 200, the crushed stone particles are rolled by the rolling roller 103, and the shielding area is reduced relative to the plate, which does not affect the continuous feeding of the crushed stone from the feed port 101, and the outermost crushed stone circumference can be pushed inward at the same time, so that the crushed stone is fully rolled, the crushed stone rolling efficiency and the uniformity of the crushed stone particles are improved, so that the discharged crushed stone particles are better used in the bridge construction base, and the base quality is improved;

[0038] The material shifting and turning mechanism 200 includes a material shifting plate 201 located outside the rolling roller 103. The material shifting plate 201 is located on the back side of the rolling roller 103 in the rotation direction. The crushed stones are first rolled by the rolling roller 103. The crushed stones after rolling may roll outwards. Then, the material shifting plate 201 is moved inwards to push the crushed stones at the edge. The upper surface of the roller frame 106 is provided with a reciprocating member 203 for driving the material shifting plate 201 to reciprocate and shift the crushed stones at the edge inwards.

[0039] A turning roller 202 is provided on the inner surface of the lower end of the material shifting plate 201. The turning roller 202 can push the edge crushed stones inward as the material shifting plate 201 shifts the materials, and can also turn over the crushed stones for shifting the materials. As the material shifting plate 201 shifts the materials, the crushed stones can be turned over, so that the rolling roller 103 can repeat the rolling of the turned over gravel.

[0040] In this embodiment, preferably, the reciprocating member 203 includes a guide rail 2035 obliquely fixed on the surface of the roller frame 106, and the reciprocating member 203 also includes a driving motor 2031 fixed on the upper surface of the roller frame 106. The upper surface of the roller frame 106 may also be provided with a shell for protecting the driving motor 2031 and other components. The upper surface of the roller frame 106 is provided with a support frame for supporting the driving motor 2031, and a flip wheel 2032 is provided at one end of the driving motor 2031. An eccentric plate 2033 is rotatably provided on the flip wheel 2032. The material stripping plate 201 is L-shaped and the lower end is semicircular. A lug is provided at the upper end of the material stripping plate 201, and a rotating plate 2034 is rotatably provided between the outer end of the eccentric plate 2033 and the lug, and the two are rotatably connected. In order to adapt to the rotation of the flip wheel 2032, the lower surface of the upper end of the material stripping plate 201 is slidably connected to the guide rail 2035, so that the material stripping plate 201 moves back and forth along the guide rail 2035.

[0041] In this embodiment, preferably, a lifting component 204 is provided between the upper end of the material stripping plate 201 and the guide rail 2035. When the material stripping plate 201 moves outward, it moves upward synchronously with the lifting component 204. A space is left between the material stripping plate 201 and the bottom, so that the space left when the material stripping plate 201 moves outward will not push the gravel outward, and the material stripping plate 201 moves inward to push the gravel on the edge inward, and the lifting component 204 includes a guide slider 2041 slidably mounted on the guide rail 2035, and the two are slidably connected to facilitate the subsequent limiting effect on the material stripping plate 201, and a fixed protrusion 2042 is provided on the surface of the guide slider 2041, and a guide column 2043 penetrating the fixed protrusion 2042 is provided on the lower surface of the material stripping plate 201. The two are slidably connected and do not affect the up and down movement of the material stripping plate 201.

[0042] In this embodiment, preferably, a lower wedge block 2045 is provided on the outer side of the guide rail 2035, and a support plate 2046 is provided between the two. The support plate 2046 firmly supports the lower wedge block 2045, and an upper wedge block 2044 located on the inner side of the lower wedge block 2045 is provided on the lower surface of the upper end of the material removal plate 201. The inclined surfaces of the two are fitted together to drive the material removal plate 201 to rise and fall.

[0043] In summary, when in use, as the rolling roller 103 rotates to roll the gravel, the driving motor 2031 works, driving the flip wheel 2032 to rotate, driving the eccentric plate 2033 to rotate along with the flip wheel 2032, and the eccentric plate 2033 rotates while driving the rotating plate 2034 to rotate at a certain angle, and the position of the rotating outer end of the rotating plate 2034 changes, thereby driving the material-diverting plate 201 to move inward or outward. When the material-diverting plate 201 moves inward, it drives the guide column 20 43 and the guide slider 2041 move along the guide rail 2035, the upper wedge block 2044 is separated from the lower wedge block 2045, at this time, the lower end of the material-diverting plate 201 contacts the bottom, and pushes the crushed stone located inside the material-diverting plate 201 inward, and is located at a position where it can be crushed by the crushing roller 103, and the material-turning roller 202 turns the crushed stone as the material-diverting plate 201 moves, and when the material-diverting plate 201 moves outward, it drives the guide slider 2041 to move outward along the guide rail 2035, and waits for the upper wedge block 2044 to be released. When the inclined surface 2044 fits the lower wedge block 2045, it will drive the upper wedge block 2044 and the material-diverting plate 201 to move upward, and the guide column 2043 will move upward in the fixed protrusion 2042, but the two will not separate. There is a certain space between the lower end and the bottom of the material-diverting plate 201, so that when the material-diverting plate 201 moves outward, it will not push the crushed stone outward again to the range where the rolling roller 103 cannot be rolled. When the material-diverting plate 201 moves outward to the limit position, it will be located outside the crushed stone. The material-shifting plate 201 continues to move inward, and the upper wedge block 2044 is separated from the lower wedge block 2045. The material-shifting plate 201 moves downward due to gravity until it touches the ground, making it convenient to push the crushed stones on the edge inward again. During the whole process, the crushed stones in the circumferential direction can be continuously pushed inward, making it convenient to be rolled and processed by the rolling roller 103, so that the crushed stones can be fully processed, and the discharged crushed stone particles are relatively uniform, which is convenient for application in the field of bridge construction, providing a solid and stable base for bridges, and improving the quality of the base for bridge construction.

[0044] Embodiment 2

[0045] Reference Figure 7 , which is the second embodiment of the present invention.

[0046] In this embodiment, preferably, a turning member 205 for turning over the crushed stone after rolling is arranged on the back of the roller frame 106. The turning member 205 does not affect the rolling process of the crushed stone by the rotation of the rolling roller 103, and can drive the turning member 205 to move in a circle. The material-push rod 2053 moves in a circle to slide and turn over the crushed stone after rolling. The turned over crushed stone can be rolled again by the rolling roller 103, thereby increasing the sufficiency and uniformity of the crushed stone rolling process. The turning member 205 includes a driving cylinder 2051 installed on the upper surface of the roller frame 106. The upper surface of the roller frame 106 can be provided with a protective shell to protect the driving cylinder 2051, and the protective shell does not affect the extension and movement of the mounting plate 2052. A support slider 2054 is arranged on the upper surface, a mounting plate 2052 is slidably arranged on the support slider 2054, a plurality of material shifting rods 2053 for turning over the crushed stone are evenly arranged along the length direction of the lower surface of the mounting plate 2052, the shape of the material shifting rod 2053 can be set according to the demand for material shifting of the crushed stone, a connecting plate 2055 is arranged between the piston rod inside the driving cylinder 2051 and the mounting plate 2052, as the piston rod extends, the mounting plate 2052 can be driven to reciprocate along the support slider 2054, a rectangular sliding hole for the I-shaped support slider 2054 to pass through is opened on the surface of the mounting plate 2052, the rectangular sliding hole and the support slider 2054 are slidably matched, and the mounting plate 2052 reciprocates without being separated up and down.

[0047] In summary, when in use, the rolling roller 103 rolls the crushed stone as the connecting shaft 104 rotates, driving the flipping member 205 to move in a circle. The rolling roller 103 first rolls the crushed stone, and after rolling, drives the plurality of material-shifting rods 2053 to slide the crushed stone at different diameters. The material-shifting rods 2053 slide to flip the crushed stone, exposing the crushed stone underneath. The exposed crushed stone is rolled and processed by the rotating rolling roller 103 again. When the crushed stone sliding material is flipped, the driving cylinder 2051 can be used to work. The piston rod inside the driving cylinder 2051 drives the mounting plate 2052 to cooperate along the supporting slider 2054. As the piston rod extends, it drives the mounting plate 2052 and the material-moving rod 2053 to move continuously, so that the diameter of the material-moving rod 2053 for flipping the crushed stone changes and is dislocated, thereby expanding the material-moving area and range of the crushed stone. During the whole process, the crushed stone can be continuously flipped and exposed, and the exposed crushed stone is crushed again, thereby increasing the sufficiency and uniformity of the crushed stone processing and improving the crushing efficiency of the crushed stone.

[0048] Embodiment 3

[0049] Reference Figure 8 , which is the third embodiment of the present invention.

[0050] The bottom of the rolling box 100 is preferably provided with a feeding member 300 for convenient feeding of crushed stones. The feeding member 300 can be used to rotate and feed the remaining crushed stones stranded on the supporting bottom plate 301 to avoid the crushed stones being stranded on the supporting bottom plate 301 and to ensure the amount of crushed stones discharged. At the same time, when the supporting bottom plate 301 is in a horizontal state, it cooperates with the rolling roller 103 to continue to grind the crushed stones fallen on the supporting bottom plate 301. The feeding member 300 includes a supporting bottom plate 301 horizontally located inside the rolling box 100. The supporting bottom plate 301 is in a horizontal state, which is convenient for cooperating with the rotating rolling roller 103 to grind the crushed stones. The supporting bottom plate 301 and the bottom of the rolling box 100 form a cavity. The right end of the supporting bottom plate 301 is rotatably connected to the inner wall of the rolling box 100. The rolling box 10 A first discharge port 105 is provided on the left side and is located above the left end of the support bottom plate 301. As the rolling roller 103 rotates to roll the crushed stones, the crushed stones are discharged from the first discharge port 105 in a circular shape. A support cylinder 302 for driving the support bottom plate 301 to rotate is provided at the bottom of the rolling box 100. The support cylinder 302 can support the bottom of the left end of the support bottom plate 301. A bottom rail 303 is provided on the lower surface of the left end of the support bottom plate 301. A limited sleeve 304 is slidably provided on the bottom rail 303. The two slide together and will not separate up and down. The internal rod of the support cylinder 302 is rotatably connected to the lower surface of the limited sleeve 304. An arc-shaped knocking plate 306 is provided on the bottom of the cavity and is located on the right side of the support cylinder 302. The upper end of the arc-shaped knocking plate 306 is arc-shaped, and a certain space is left between it and the support bottom plate 301 in a horizontal state.

[0051] In summary, when in use, the inner rod of the support cylinder 302 is in an extended state. At this time, the support base plate 301 is in a horizontal state. The horizontal support base plate 301 cooperates with the rolling roller 103 to roll the fallen gravel. After the rolling process is completed, most of the gravel is discharged from the first discharge port 105, while a small part of the gravel remains on the support base plate 301. At this time, the inner rod of the support cylinder 302 retracts, driving the limiting sleeve 304 to move downward, and the left end of the support base plate 301 rotates downward around the shaft. In order to adapt to the rotation of the support base plate 301, the limiting sleeve 304 slides along the bottom rail 303. The two are slidably connected and the limiting sleeve 304 is rotatably connected to the inner rod of the support cylinder 302, which is convenient for adaptation. The support base plate 301 rotates, and the bottom of the support base plate 301 rotates downward at a certain angle, and the upper end of the arc-shaped knocking plate 306 will be hit. The two will produce collision and vibration at the moment of contact. The vibration will make the retained gravel on the support base plate 301 fall down along the inclined surface faster, and when it falls on the inclined surface of the guide wedge block 305, it will be discharged from the second discharge port 107 along the inclined surface of the guide wedge block 305. As the internal rod of the support cylinder 302 continues to expand and contract, it drives the support base plate 301 to rotate slightly up and down, and continuously hit the arc-shaped knocking plate 306. The continuous vibration allows the gravel to be discharged quickly, so that there will be no gravel residue on the support base plate 301, thereby ensuring the amount of gravel discharged and facilitating the complete discharge of gravel for use in bridge construction.

[0052] In this embodiment, preferably, a second discharge port 107 located below the first discharge port 105 is opened on the left side of the lower end of the rolling box 100. When the supporting base plate 301 rotates, the left end can be located at the second discharge port 107. A guide wedge block 305 with an inclined surface facing the left side is provided on the inner side of the second discharge port 107. The guide wedge block 305 can guide the gravel falling from the left end of the supporting base plate 301.

[0053] Embodiment 4

[0054] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0055] When in use, the material-shifting and turning mechanism 200 is used to push the crushed stone located on the outside of the rolling roller 103 inward, and the crushed stone is pushed into the range where the rolling roller 103 can be rolled. During the rolling process of the rolling roller 103, the turning component 205 is used to turn the crushed stone range that cannot be covered by the turning roller 202, thereby increasing the sufficiency of the crushed stone rolling and the uniformity of the particles. This is applied to the base layer of bridge construction to improve the quality of the base layer. The crushed stone rolling process will discharge the crushed stone from the first discharge port 105, while some of the crushed stone retained in the supporting base plate 301 will be fully discharged through the discharge component 300, ensuring the discharge amount of crushed stone, which is convenient for application in the field of bridge construction.
