Description
Technical Field
[0001] The present invention relates to the technical field of bucket elevators, in particular to the technical field of a head device of a bucket elevator adaptable to various materials. Background Art
[0002] A bucket elevator is a continuous conveying machine that uses a series of buckets uniformly fixed on an endless traction member to vertically lift materials. It has the advantages of diverse items that can be conveyed, strong adaptability to the working environment, arbitrary flow direction of items, good accuracy of conveying position, controllability of conveying rhythm, long conveying distance, and the ability to withstand heavy loads and impacts.
[0003] When the bucket elevator is working, the buckets scoop up the materials from the storage below, are lifted to the top along with the chain, turn downward after bypassing the top wheel, and the bucket elevator pours the materials into the receiving trough. A chain-driven bucket elevator generally has two parallel drive chains, with a pair of drive sprockets on the upper or lower part and a pair of redirecting sprockets on the lower or upper part. A bucket elevator is generally equipped with a casing to prevent dust from flying in the bucket elevator.
[0004] At present, the discharging angle of traditional bucket elevators is fixed during design and cannot be adjusted according to the characteristics of materials (such as particle size, humidity, viscosity, etc.) or process requirements. At the same time, due to the non-adjustable discharging angle, it is difficult for the same device to adapt to the conveying requirements of different materials, resulting in low equipment utilization efficiency. Even additional multiple devices need to be configured, increasing costs and floor space. For some materials with relatively high viscosity, the fixed discharging angle may cause the materials to remain in the buckets, affecting the conveying efficiency and increasing the workload of cleaning and maintenance. An unreasonable discharging angle may lead to uneven distribution of material impact force, exacerbate equipment wear, and shorten the service life. Therefore, it is necessary to propose a head device of a bucket elevator that is adaptable to various materials and convenient to adjust. Summary of the Invention
[0005] The purpose of the present invention is to solve the problems in the prior art and propose a head device of a bucket elevator that is adaptable to various materials and convenient to adjust.

The adjusting drive mechanism is provided with the guiding shaft, and the guiding shaft is provided with the guiding wheel. The guiding wheel abuts against the outer side of the downward running section of the corresponding bucket lifting chain to change the movement trajectory of the bucket lifting chain. The material guiding mechanism is provided on the adjusting drive mechanism, and the material guiding mechanism includes two connecting rods and a material guiding plate provided on the connecting rods.
[0007] Preferably, the adjusting driving mechanism includes a connecting plate, a sealing plate, a bearing seat, an avoidance hole, a connecting seat, a lead screw, a plurality of nuts and a support. An avoidance hole is provided on the connecting plate, and a sealing plate is slidably arranged thereon for closing the avoidance hole. A connecting seat is provided on the sealing plate, and a bearing seat for installing a guide shaft is provided on the connecting seat. A lead screw penetrating through the support is provided on the connecting seat, and nuts are provided on both sides of the support for the lead screw.
[0008] Preferably, angle steel seats are provided on both the upper and lower sides of the avoidance hole on the connecting plate, and stoppers located outside the sealing plate are provided on the angle steel seats.
[0009] Preferably, the guide shaft penetrates through the sealing plate, and a sealing ring fixedly connected to the sealing plate is sleeved on the guide shaft.
[0010] Preferably, an annular protrusion is provided on the circumferential surface of the guide wheel, and the annular protrusion is located between the outer link plates on both sides of the downward running section of the hopper lifting chain.
[0011] Preferably, support seats elastically connected to the corresponding sealing plates are provided at the upper ends of the connecting rods. A sliding groove hole is provided on the support seat, and a sliding body fixedly connected to the corresponding connecting rod is provided in the sliding groove hole. A spring is provided between the end of the sliding body away from the sealing plate and the end of the sliding groove hole away from the sealing plate.
[0012] Preferably, the upper end of the material guiding plate is bent forward to form an inclined material guiding portion, and a wear-resistant plate fixed by screws is provided on the upper surface of the inclined material guiding portion.

[0014] Preferably, a maintenance door is provided at the rear side of the head casing, which is convenient for observation and maintenance work.
[0015] Advantages of the present invention: By changing the movement trajectory of the corresponding hopper lifting chain through the discharge angle adjusting device, the running trajectory of the hopper assembled on the hopper lifting chain is further changed, so as to change the discharge angle when the hopper discharges materials. In addition, the discharge angle adjusting device simultaneously drives the material guiding mechanism to perform position adjustment, so that when the hopper with an adjusted angle discharges materials, the materials can smoothly pass through the material guiding mechanism and enter the discharge port. Compared with the prior art, it can adapt to the conveying of various materials, and the adjustment is convenient and fast.
