Abstract
Description
Technical Field
[0001] The utility model relates to a receiving and guiding chute for a conveyor. Background Art
[0002] When the conveyor receives materials, the materials generally fall from the upstream conveyor with a certain height difference. The impact of the materials causes particle splashing and dust raising. The conventional method is to set up a guiding chute. The two sides of the guiding chute are steel plates and rubber plates. There is a tiny gap between the rubber plate and the conveyor belt to block part of the dust from overflowing, which has a certain sealing effect. However, relying only on the single-layer rubber plate for sealing, it is impossible to form an effective and complete seal with the moving conveyor belt, and some dust and particles will overflow.

[0021] The following further elaborates the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.
[0022] Conveyor receiving and guiding chute in Embodiment 1
[0023] AsFigure 1 and Figure 2 As shown in Figure 2 , the receiving and guiding chute of the conveyor includes: a diversion hard seal plate 1, a Y-shaped double-layer dust-proof skirt plate 2, a slide plate 3, a bracket 4, a roller group 5, and a shield 6.
[0024] The roller group 5 is of a three-roller trough type structure. The three groups of rollers are respectively fixed on the base 8. The middle roller group is axially horizontal, and the two short roller groups on both sides are respectively inclined 35° upward obliquely. The middle roller and the two short rollers on both sides bear most of the material weight.
[0025] The main body of the conveyor belt 7 is placed above the roller group 5 and is supported by the roller group. The outer edges on both sides of the conveyor belt overlap on the slide plate 3. The slide plate 3 is fixed on the bracket 4, and the bracket 4 is welded to the side wall of the shield 6.
[0026] As Figure 1 、 Figure 2 and Figure 3 shown, there are two diversion hard seal plates 1 on the left and right, which are relatively arranged on both sides above the conveyor belt 7. The diversion hard seal plate 1 includes a main board 11 and a side board 12. The main board is vertically arranged along the edge of the conveyor belt 7. Its upper edge is welded to the top of the shield 6, and its lower edge is close to the surface of the conveyor belt 7.
[0027] As Figure 3 shown, the main board 11 includes a steel plate 111 and a lining plate 112. The material of the steel plate 111 is Q235 steel plate, and the lining plate 112 is a ceramic wear-resistant material. Round holes are drilled on the steel plate 111, and counterbore holes are drilled on the lining plate 112. The lining plate and the steel plate are connected by countersunk head bolts 113. The main board 11 can guide the material flow to the center of the belt, which belongs to the first seal, reduces the outward flying particles of the material, and reduces the probability of belt deviation.
[0028] As Figure 1 、 Figure 2 and Figure 3 shown, the side board 12 is welded to the side of the main board facing away from the material and is perpendicular to the inclined surface of the conveyor belt 7. The Y-shaped double-layer dust-proof skirt plate 2 is buckled on the side board 12. As shown in Figure 4 a, the Y-shaped double-layer dust-proof skirt plate 2 is a rubber material plate with a cross-section of "Y". The edges of the double-layer plate at the end are in sliding contact with the conveyor belt 7, effectively isolating dust.
[0029] As Figure 4 b shown, the Y-shaped double-layer dust-proof skirt plate 2 is fixed on the side board 12 through a fastener 21. The fastener 21 is screwed with a nut 211 welded on the side board 12. The fasteners 21 are arranged in groups every 500 mm. Through the pressing angle steel or angle aluminum 212, the Y-shaped double-layer dust-proof skirt plate 2 is closely attached to the side board 12. The angle steel or angle aluminum 212 is equal in length to the Y-shaped double-layer dust-proof skirt plate 2.
[0030] The Y-shaped double-layer dust-proof skirt board has excellent sealing performance and belongs to the second seal to prevent dust and small particles from overflowing from the material chute. The material of natural rubber also reduces the wear on the conveyor belt.
[0031] The material of the slide plate 3 is UPE ultra-high molecular weight polyethylene, which continuously supports the belt and forms the third seal together with the belt to prevent dust from overflowing.
[0032] The shield 6 is the fourth seal. The top is designed in an arc shape, which increases the area of the material chute, reduces the induced wind speed generated when the material falls, reduces the amount of dust, and prevents the dust from spreading into the environment.
[0033] The length of the material chute is 150 - 200 cm. The height of the diversion hard seal plate 1 is 30 - 100 cm.
[0034] This material chute has a total of four seals, which can seal most of the particles and dust inside the material chute. Used in conjunction with a dust collector, the dust-containing air sealed inside the material chute is drawn away and treated, which can prevent dust from spreading into the environment and has important significance in dust suppression and environmental protection.
