Description

Technical Field

[0001] The invention relates to the technical field of asphalt production, in particular to a full-automatic stone material taking system. Background Art

[0002] Stone is an important raw material for asphalt mixing plants to mass produce asphalt concrete. Asphalt mixing plants mix stone, asphalt, sub-materials and additives in a certain ratio to produce asphalt mixtures, modified asphalt mixtures, colored asphalt mixtures, etc., which are widely used in the construction of expressways, grade highways, municipal roads, airports, ports and other fields.

[0003] In the prior art, a loader is manually operated to take materials from a stone silo and transport them to the hopper inlet of an asphalt mixing plant. However, the efficiency of manually operated loaders in taking materials is low, and there is dust at the production site, resulting in a poor working environment and a hazard to the health of operators. Summary of the invention

[0004] Based on this, it is necessary to provide a fully automatic stone taking system to address the problems of low work efficiency, poor working environment and harm to the health of operators in the existing manual taking technology.

[0005] The technical solution adopted by the present invention is as follows:

[0038] The structure and function of the present invention are as follows:

[0039] like Figure 1-Figure 10 As shown, a fully automatic stone material taking system includes a gantry 3, on which several taking units and several feeding belts 5 are mounted, the feeding belts 5 correspond to the taking units one by one, the discharging end of a single taking unit is arranged toward the feeding belt 5, and the single taking unit digs the material and unloads the material onto the feeding belt 5, so that the material is discharged through the feeding belt 5. By setting the taking unit, unattended operation can be realized, and the operator can be effectively prevented from being in a harsh working environment, thereby avoiding harm to the health of the operator, reducing labor costs and safety risks, and providing strong support for the sustainable development of the stone industry.

[0040] like Figure 3 As shown, a single reclaiming unit includes a slide mechanism 1, on which a reclaiming mechanism 2 is mounted, and the slide mechanism 1 drives the reclaiming mechanism 2 to move to the material pile, so that the reclaiming mechanism 2 digs the material and unloads the material onto the feeding belt 5. The slide mechanism 1 is used to drive the reclaiming mechanism 2 to the material pile, so that the reclaiming mechanism 2 can dig the material conveniently; the reclaiming mechanism 2 can dig the material piled on the ground, and lift and transfer the material to the feeding belt 5 above the material pile, so as to supply the rear equipment (such as the asphalt mixing plant) through the feeding belt 5.

[0041] In the present invention, each reclaiming unit works and is controlled independently, and the control method is simple and reliable, and can effectively improve the working efficiency of the reclaiming system.

[0042] like Figure 4-Figure 6 As shown, the structure of the single slide mechanism 1 is as follows: it includes a first transverse shift seat 101, a first active rotary wheel group and a first driven rotary wheel group are respectively installed at the bottom of the first transverse shift seat 101, the first active rotary wheel group includes two first active rotary wheels rotatably installed on the first transverse shift seat 101, a single first active rotary wheel is connected to the output end of the first motor 103, and the two first motors 103 drive the corresponding first active rotary wheels to rotate simultaneously, so that the first transverse shift seat 101 performs reciprocating linear motion along the horizontal X direction on the gantry 3; The top of a transverse seat 101 is matched with a second transverse seat 102, and the bottom of the second transverse seat 102 is respectively equipped with a second active rotary wheel group and a second driven rotary wheel group, the second active rotary wheel group includes two second active rotary wheels rotatably mounted on the second transverse seat 102, a single second active rotary wheel is connected to the output end of the second motor 104, and the two second motors 104 drive the corresponding second active rotary wheels to rotate simultaneously, so that the second transverse seat 102 makes a reciprocating linear motion along the horizontal Y direction on the first transverse seat 101. The horizontal Y direction and the horizontal X direction are two mutually perpendicular directions on the horizontal plane, the first motor 103 drives the first transverse seat 101 to make a reciprocating linear motion along the horizontal X direction through the first active rotary wheel group, and the second motor 104 drives the second transverse seat 102 to make a reciprocating linear motion along the horizontal Y direction through the second active rotary wheel group, so that the corresponding material picking mechanism 2 can be driven to move to any position within a certain spatial range, so that the material picking mechanism 2 can reach the corresponding working position to pick up the corresponding material pile.

[0043] Two parallel and spaced transverse tracks 105 are fixed on the single first transverse seat 101, and the transverse tracks 105 are used to be installed in coordination with the second driving rotating wheel group and the second driven rotating wheel group. The transverse tracks 105 are arranged along the horizontal Y direction.

[0044] A buffer conveyor belt 107 is also installed on the top of the single first transverse shift seat 101, and a first feeding nozzle 106 is installed at one end of the buffer conveyor belt 107, and the discharge port of the first feeding nozzle 106 faces the feeding belt 5. The buffer conveyor belt 107 is used to temporarily store the materials dug by the material taking mechanism 2. The buffer conveyor belt 107 conveys the materials on it to the first feeding nozzle 106 at its end, and then delivers them to the feeding belt 5 through the first feeding nozzle 106.

[0045] like Figure 1-Figure 2As shown, a plurality of slide rail assemblies are installed on the gantry 3, and the slide rail assemblies are arranged one by one with the slide seat mechanism 1, and the slide rail assemblies are used to be installed in cooperation with the corresponding first active rotating wheel group and the first driven rotating wheel group. A single set of slide rail assemblies includes two slide rails 4 arranged in parallel at intervals, and the slide rails 4 are used to be installed in cooperation with the corresponding second active rotating wheel group and the corresponding second driven rotating wheel group, and the slide rails 4 are arranged along the horizontal X direction.

[0046] In a single slide mechanism 1, a plurality of first brackets 108 are fixed at intervals along the horizontal Y direction on the first transverse seat 101, and a through-beam sensor receiver is installed on a single first bracket 108; a through-beam sensor transmitter is installed on the second transverse seat 102 through a second bracket 109. When the second transverse seat 102 moves relative to the first transverse seat 101, the through-beam sensor transmitter emits a laser signal, and the laser signal is received by the corresponding through-beam sensor receiver, thereby positioning the second transverse seat 102. By providing the through-beam sensor receiver and the through-beam sensor transmitter, the moving position of the material picking mechanism 2 can be effectively monitored, thereby realizing automatic positioning of the material picking mechanism 2.

[0047] like Figure 7-Figure 10 As shown, the structure of a single material taking mechanism 2 is as follows: it includes a material taking shell 201 with a hollow interior, a second feeding nozzle 210 is arranged on the upper wall surface of the material taking shell 201, an opening is arranged on the lower wall surface of the material taking shell 201, a driving sprocket 205 is rotatably installed on the upper part of the material taking shell 201, and a driven sprocket 206 is rotatably installed on the lower part of the material taking shell 201, the driven sprocket 206 is arranged directly below the driving sprocket 205, and a driven sprocket 206 is installed in cooperation with the driving sprocket 205. The transmission chain 207 and the driving sprocket 205 rotate under the driving action of the material taking motor 202, so that the transmission chain 207 circulates and rotates between the driven sprocket 206 and the driving sprocket 205; a plurality of buckets 208 are installed on the transmission chain 207, and a single bucket 208 digs materials from the opening of the material taking shell 201, and transmits them to the second feeding nozzle 210 through the circulated transmission chain 207 for unloading, so that the materials are discharged through the second feeding nozzle 210. In the process of the circulated rotation of the transmission chain 207, the bucket 208 located at the opening of the material taking shell 201 is turned over by the transmission chain 207, so as to dig materials in the material pile; the bucket 208 located at the second feeding nozzle 210 is turned over by the transmission chain 207, so as to throw the materials inside it into the second feeding nozzle 210 for unloading.

[0048] In the present invention, the opening on the material taking shell 201 and the second material feeding nozzle 210 are respectively arranged on two opposite side wall surfaces of the material taking shell 201 .

[0049] In a single material taking mechanism 2, a driving sprocket 205 is rotatably mounted inside the material taking shell 201 via a first rotating shaft 203, and the end of the first rotating shaft 203 is connected to the output end of the material taking motor 202; a driven sprocket 206 is rotatably mounted inside the material taking shell 201 via a second rotating shaft 204. By providing the first rotating shaft 203 and the second rotating shaft 204, the motion stability of the driving sprocket 205 and the driven sprocket 206 can be improved.

[0050] Several front brackets 209 are mounted on the outer wall of the material taking shell 201. The front brackets 209 are arranged above the opening of the material taking shell 201. The front brackets 209 are used to loosen the material pile. By setting the front brackets 209, when the bucket 208 is digging materials, the front brackets 209 can be inserted into the material pile to loosen the material pile, so that the materials above the material pile can fall downward, thereby improving the digging efficiency of the bucket 208.

[0051] In the present invention, a conveyor belt (not shown in the drawings) is installed on the buffer conveyor belt 107 and the feeding belt 5 to transport the stones.

[0052] The working process of the present invention is as follows:

[0053] Step 1: The two first motors 103 are started at the same time, driving the corresponding first active wheels to rotate at the same time, thereby driving the first transverse shift seat 101 to move linearly along the slide track 4, and then driving the material taking mechanism 2 to the side of the material pile, and then the two first motors 103 are stopped;

[0054] Step 2: The two second motors 104 are started simultaneously to drive the corresponding second active wheels to rotate simultaneously, thereby driving the second transverse movement seat 102 to move linearly along the transverse movement track 105, and further driving the material taking mechanism 2 to continue to approach the material pile;

[0055] At the same time, the material taking motor 202 is started, driving the driving sprocket 205 to rotate through the first rotating shaft 203, thereby driving the bucket 208 to rotate cyclically through the transmission chain 207;

[0056] Step 3: The bucket 208 in contact with the material pile digs the material, and then under the lifting and conveying of the transmission material bar 207, the bucket 208 drives the material to be lifted upward to the second feeding nozzle 210, and the bucket 208 turns over to discharge the material inside it into the second feeding nozzle 210, and the material is conveyed to the buffer conveyor belt 107 through the second feeding nozzle 210;

[0057] When the bucket 208 digs materials, the two second motors 104 continue to work, thereby driving the material taking mechanism 2 to continue to approach the material pile. At the same time, the front bracket 209 is inserted into the material pile to loosen the material pile, so that the materials above the material pile can fall downward, thereby improving the digging efficiency of the bucket 208;

[0058] Step 4: The material on the buffer conveyor belt 107 is conveyed to the first feeding nozzle 106 through the buffer conveyor belt 107, and then conveyed to the loading belt 5 through the first feeding nozzle 106;

[0059] Step 5: The material on the feeding belt 5 is transported to the back-end equipment via the feeding belt 5, thereby automatically feeding the back-end equipment.
