Description

Technical Field

[0001] The utility model relates to the technical field of dischargers, in particular to a curved plow type discharger. Background Art

[0002] A plow-type discharger is a commonly used unloading device on a belt conveyor. Existing plow-type dischargers are divided into single-sided dischargers and double-sided dischargers according to the discharge position. The single-sided discharger mainly distributes material to one side of the belt, and its plowshare style is usually straight. The double-sided discharger distributes material to both sides of the belt, and the plowshare style is mostly V-shaped, and usually a double-plowshare style. When different material distribution requirements arise during operation, it is necessary to switch between the two dischargers, which is relatively inconvenient. Utility Model Content

[0003] The utility model aims to provide a curved plough type discharger, which has the effect of freely switching the discharger between single-side discharge and double-side discharge according to processing requirements.

[0004] The above technical purpose of the present utility model is achieved through the following technical solutions: a curved plow type discharger, comprising a base, a roller frame and a plow head assembly, the base is equipped with a driving mechanism for driving the roller frame and the plow head assembly to rise and fall, the plow head assembly comprises a fixing member and a first plow blade fixed on both sides of the fixing member, the fixing member is equipped with a second plow blade for cooperating with the first plow blade for single-sided unloading.

[0005] By adopting the above technical solution, the unloader cooperates with the conveying device. During double-sided unloading, the first plowshares on both sides of the fixed part are used to unload the material, and the material is guided to both sides of the roller frame. During single-sided unloading, the second plowshare is installed on the fixed part and cooperates with the first plowshare on the left or right side of the fixed part to guide the material to the left or right side of the roller frame, thereby realizing free switching between single-sided unloading and double-sided unloading according to work needs, thereby improving the versatility of the equipment.

[0006] The present invention is further configured as follows: the first coulter is configured as a curve.

[0007] By adopting the above technical solution, the material can enter the hoppers on both sides accurately and smoothly in a parabolic form during unloading, reducing the problem of material spillage during unloading.

[0008] The present invention is further configured as follows: the first coulter includes a main coulter and an auxiliary coulter, the main coulter is made of high chromium manganese alloy, and the auxiliary coulter is made of fluorine-grafted modified heat-resistant polyurethane.

[0009] By adopting the above technical solution, the main plow blade adopts high chromium manganese alloy so that it can withstand greater impact force and pressure, and is not easy to break or deform during operation; the auxiliary plow blade adopts fluorine-grafted modified heat-resistant polyurethane to give it good elasticity and toughness, which can effectively absorb impact force, reduce damage to equipment during operation, and improve work safety.

[0010] The present invention is further configured as follows: the second coulter is configured in a curved shape connected to the first coulter.

[0011] By adopting the above technical solution, the first coulter and the second coulter are connected and cooperated with the single-side guided unloading, and the unloading is cleaner.

[0012] The present invention is further configured such that the bottom ends of the first coulter and the second coulter are both provided with an inclination angle.

[0013] By adopting the above technical solution, the material can be plowed up easily and smoothly. Compared with the straight plow blade, the resistance during unloading is smaller, the flushing friction of the plow blade is also smaller, and the equipment is more durable.

[0014] The present invention is further configured as follows: mounting plates are fixed on both sides of the first coulter, and through holes are provided on adjacent sides of the two first coulters. The mounting plates pass through the through holes and are fixed to the fixing members via connecting members.

[0015] By adopting the above technical solution, the mounting plate is installed on the fixing part through the connecting part, and then the second coulter is fixed relative to the fixing part, so that the first coulter and the second coulter cooperate to unload on one side; the connecting part is also convenient for disassembly, and the second coulter is removed from the fixing part when double-sided unloading is required.

[0016] The present invention is further configured as follows: the connecting member is configured as a mounting bolt that is threadedly connected to the mounting plate and extends into the fixing member.

[0017] By adopting the above technical solution, the mounting bolts can provide high connection strength while being convenient for disassembly and reassembly, and are suitable for bearing large tensile and shear forces.

[0018] The utility model is further configured as follows: the driving mechanism includes a hydraulic cylinder hinged to the base, a connecting frame hinged to the base and a movable frame hinged to the base, the fixing member is fixed to the movable frame, the output end of the hydraulic cylinder is hinged to the connecting frame, and a first connecting rod is fixed between the connecting frame and the movable frame.

[0019] By adopting the above technical solution, when the unloading work begins, the output end of the hydraulic cylinder extends through the first connecting rod and the connecting frame to push the movable frame to rotate and descend relative to the base, and then the movable frame drives the plowshare assembly to descend.

[0020] The present invention is further configured as follows: a support rod is hinged between the roller frame and the base, and a second connecting rod is hinged between the support rod and the connecting frame.

[0021] By adopting the above technical solution, the output end of the hydraulic cylinder extends out through the connecting frame and the second connecting rod to pull the roller frame up relative to the base, and finally the bottom side of the plow head assembly and the upper side of the roller frame are in contact with each other to perform unloading work; the driving mechanism can adjust the height of the plow blade to better contact the conveyor belt. During operation, the plow blade will not be lifted or shaken by the impact force of the material, thereby avoiding the conveyor belt from being torn, worn and leaking coal.

[0022] The present invention is further configured as follows: a plurality of support rods are provided, and the plurality of support rods are located at the four corners of the roller frame.

[0023] By adopting the above technical solution, multiple support rods jointly support the roller frame, making the overall structure more stable.

[0024] The beneficial effects of the utility model are:

[0025] 1. The unloader cooperates with the conveying device. In double-sided unloading, the first coulters on both sides of the fixed part are used to unload the material, guiding the material to the two sides of the roller frame. In single-sided unloading, the second coulter is installed on the fixed part and cooperates with the first coulter on the left or right side of the fixed part to guide the material to the left or right side of the roller frame. This allows free switching between single-sided unloading and double-sided unloading according to operational needs, thereby improving the versatility of the equipment.

[0026] 2. The main coulter is made of high-chromium manganese alloy, which enables it to withstand greater impact and pressure and is not easily broken or deformed during operation. The auxiliary coulter is made of fluorine-grafted modified heat-resistant polyurethane, which has good elasticity and toughness, can effectively absorb impact, reduce damage to equipment during operation, and improve work safety.

[0027] 3. The driving mechanism can adjust the height of the plow blade so that it is close to the conveyor belt at the best surface. During operation, the plow blade will not be lifted or shaken by the impact of the material, thus avoiding the conveyor belt from being torn, worn and leaking coal. BRIEF DESCRIPTION OF THE DRAWINGS
