Description

Technical Field

[0001] This utility model relates to the field of feeding shoe technology, and specifically discloses a feeding shoe. Background Technology

[0002] Feed shoes are an important component in the field of bulk material conveying and transfer equipment. They are widely used in various bulk material conveying operations, such as material conveying systems in industries like coal, ore, grain, and chemical raw materials. Especially in situations requiring precise control of material flow and reduction of dust pollution, feed shoes play an irreplaceable role.

[0003] The feed shoe mainly consists of the feed shoe housing. The feed shoe housing has a feed shoe flange at the inlet for easy connection to upper components (such as the discharge pipe), ensuring the feed shoe is properly adjusted before fixing. Material falls from the upper discharge pipe into the feed shoe inlet. Through its unique U-shaped gradient cross-section design, the feed shoe gradually gathers the material during transport and smoothly conveys it to the belt conveyor or other conveying equipment.

[0004] There are two main methods for adjusting material flow in existing feed shoes: one is to install adjusting baffles in the upstream hopper and chute and adjust them by handwheel. This method has many drawbacks, including low adjustment efficiency, being very cumbersome, high labor costs, difficulty in adjusting as needed, and limited adjustment of the amount of material falling. The other method is to install a guide chute adjusting baffle at the material drop point. This method also cannot be adjusted as needed and has limited adjustment of the amount of material flow. Furthermore, the material falling from the upstream cannot fall from the middle, which easily leads to material leakage. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a feeding shoe to solve the problem of inconvenience in adjusting the amount of material falling as needed.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A feeding shoe includes a housing with a double-leaf door at the upper opening. Two symmetrically arranged drop plates are positioned inside the housing, below the double-leaf door. The upper ends of the drop plates are hinged to the edge of the upper opening of the housing. The lower ends of the two drop plates abut against each other. A reset mechanism is connected to the center of the bottom surface of each drop plate. The end of the reset mechanism away from the drop plate is located on the side wall of the housing. The reset mechanism includes a screw that penetrates the side wall of the housing. Two nuts are mounted on the screw, located on the inner and outer sides of the housing, respectively. A spring is fixedly attached to one end of the screw, with the end of the spring away from the screw fixedly connected to the bottom surface of the drop plate. The length of the screw inside the housing can be adjusted using the two nuts according to the amount of material falling, thereby adjusting the compression of the spring. When the weight of the material accumulated at the two drop plates exceeds the spring force, the drop plates further compress the spring, causing the material to fall. The adjustment operation is simple.

[0008] Preferably, the inner wall of the housing is equipped with two V-shaped baffles on both the front and rear sides, which are fitted with two material drop plates. The V-shaped baffles are positioned between the material drop plates and the double doors. The V-shaped baffles limit the distance the two material drop plates can rotate inward, ensuring that the material falls to the contact point between the two material drop plates.

[0009] Preferably, a rotating shaft is rotatably provided on both the left and right edges of the opening at the upper end of the housing; the upper end of the blanking plate is fixedly mounted on the rotating shaft. This completes the hinge connection of the blanking plate to the housing.

[0010] Preferably, the double door comprises two oppositely arranged door panels; the door panels are disposed at the upper opening of the housing via a gear and rack assembly.

[0011] Preferably, the gear and rack assembly includes a side gear and a middle gear; the side gears are rotatably mounted on a rotating shaft; the side gears are all located on the front and rear side walls of the housing; the middle gear is rotatably mounted on the front and rear inner walls of the housing and is located at the opening at the upper end of the housing; racks are provided on the front and rear sides of one side of the door panel in conjunction with the side gears and the middle gear. This allows the middle gear to rotate when one door panel is opened, thereby simultaneously opening the other door panel, ensuring that material falls from the middle of the two door panels and reducing material leakage.

[0012] Preferably, a round rod is provided on the front and rear walls of the inner side of the housing; the round rod is located below the central gear; one of the door panels is located between the central gear and the round rod. This ensures that the rack on the door panel meshes with the central gear and the side gear, ensuring that the two door panels move simultaneously.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. With the reset mechanism, the length of the screw inside the housing can be adjusted by using two nuts according to the amount of material falling, thereby adjusting the compression of the spring. When the weight of the material accumulated at the two drop plates is greater than the spring force, the drop plates further compress the spring, and the material falls. The adjustment operation is simple.

[0015] 2. By setting up the gear and rack assembly, when one door panel is opened, the central gear is driven to rotate, which in turn drives the other door panel to open at the same time, ensuring that the material falls from the middle of the two door panels and reducing material leakage.

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0023] like Figure 1-3As shown, a feeding shoe includes a housing 1 with a double-door at the upper opening. The double-door comprises two opposing door panels 8, which are connected at the upper opening of the housing 1 via a gear and rack assembly. Rotating shafts 7 are rotatably mounted on both sides of the upper opening of the housing 1. The gear and rack assembly includes side gears 9 and a central gear 10. The side gears 9 are rotatably mounted on the rotating shafts 7 and are located on the front and rear side walls of the housing 1. The central gear 10 is rotatably mounted on the inner front and rear walls of the housing 1 and is located at the upper opening of the housing 1. Racks are provided on the front and rear sides of one side of each door panel 8, cooperating with the side gears 9 and the central gear 10. A round rod 11 is provided on the inner front and rear walls of the housing 1, positioned below the central gear 10. One door panel 8 is located between the central gear 10 and the round rod 11. Opening one door panel 8 drives the central gear 10 to rotate, simultaneously opening the other door panel 8, ensuring that material falls from the middle of the two door panels 8 and reducing material leakage.

[0024] In the above configuration, two material drop plates 2 are symmetrically arranged inside the housing 1; the two material drop plates 2 are located below the double doors; two protrusions are provided on the upper end of the material drop plates 2, and the protrusions are fixedly mounted on the rotating shaft 7. The right door panel 8 passes through the two protrusions on the upper end of the material drop plates 2. The lower ends of the two material drop plates 2 abut against each other; V-shaped baffles 6 are provided on both the front and rear sides of the inner wall of the housing 1 to cooperate with the two material drop plates 2; the V-shaped baffles 6 are located between the material drop plates 2 and the double doors, which can limit the distance of the two material drop plates 2 to rotate inward, ensuring that the material falls to the abutment point of the two material drop plates 2.

[0025] Each blanking plate 2 has a reset mechanism connected to the center of its bottom surface. The end of the reset mechanism away from the blanking plate 2 is located on the side wall of the housing 1. The reset mechanism includes a screw 3, which passes through the side wall of the housing 1. Two nuts 4 are installed on the screw 3, located on the inner and outer sides of the housing 1 respectively. A spring 5 is fixedly installed at one end of the screw 3, and the end of the spring 5 away from the screw 3 is fixedly connected to the bottom surface of the blanking plate 2. A through hole is provided in the side wall of the housing 1 at the screw 3. The through hole is elongated and its inner diameter is equal to the outer diameter of the screw 3. The two nuts 4 are spaced apart by a certain distance, which is slightly greater than the thickness of the side wall of the housing 1. This ensures that the axis of the screw 3 can be set at an acute angle to the side wall of the housing 1, facilitating the movement of the screw 3 within the through hole.

[0026] Depending on the size of the conveyor belt below the feed shoe and the type of material, the appropriate material drop amount is adjusted by using two nuts 4 to adjust the length of the screw 3 inside the housing 1, thereby adjusting the compression of the spring 5. When the weight of the material accumulated at the two drop plates 2 exceeds the spring force of the spring 5, the drop plates 2 further compress the spring 5, causing the material to fall. The adjustment operation is simple. When the weight of the residual material is less than the spring force of the spring 5, the drop plates 2 reset under the action of the spring force of the spring 5, facilitating the next material drop.
