[0041] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0042] like Figure 1-Figure 7As shown, the utility model discloses a double-sealed conveying system, including a frame 1, a conveyor belt 2 and a dust cover 3. The conveyor belt 2 is arranged on the frame 1 and is transmitted from left to right. The dust cover 3 is arranged above the conveyor belt 2 to cover the conveyor belt 2. A dustproof chamber 31 is surrounded by the dust cover 3 and the conveyor belt 2.

[0043] Therefore, the material to be transported is placed on the conveyor belt 2, and the conveyor belt 2 is operated to transport the material from left to right. Under the action of the dust cover 3, the dust raised on the conveyor belt 2 is confined to the dustproof chamber 31, thereby achieving a dustproof effect.

[0044] Among them, the conveyor belt 2 includes a main transmission section 21 and inclined transmission sections 22 located on both sides of the width of the main transmission section 21. The main transmission section 21 is horizontal, and the inclined transmission section 22 is inclined upward along the horizontal direction away from the main transmission section 21. Therefore, the upper space of the conveyor belt 2 is a trapezoidal structure that is narrow at the bottom and wide at the top, so that the materials falling on the conveyor belt 2 are mainly concentrated in the main transmission section 21, and under the action of the inclined transmission section 22, the materials are prevented from falling out of the conveyor belt 2 to the front and rear sides, making the transmission more stable.

[0045] In addition, the frame 1 is provided with a support plate 11 that fits the inclined transmission section 22 below each inclined transmission section 22 to support the inclined transmission section 22. In addition, the dust cover 3 is provided with a first seal 4 and a second seal 5 above each inclined transmission section 22, wherein the first seal 4 and the second seal 5 are both made of elastic material, such as rubber material, silicone material, and the first seal 4 is in an arc-shaped deformation state that is inclined downward and toward the main transmission section 21, so that one side of the first seal 4 abuts against the upper surface of the inclined transmission section 22, and the second seal 5 extends vertically downward and abuts against the upper surface of the inclined transmission section 22.

[0046] Therefore, 1. under the action of the support plate 11, the inclined transmission section 22 is supported so that the upper surface of the inclined transmission section 22 presents a flat plane structure, so that the first seal 4 and the second seal 5 abutting on the inclined transmission section 22 have a better sealing effect, and prevent the inability to fully seal due to the uneven upper surface of the inclined transmission section 22; 2. The first seal 4 is bent so that one side surface abuts against the upper surface of the inclined transmission section 22. Under the elastic reset of the first seal 4, the inclined transmission section 22 is clamped by the support plate 11 and the first seal 4 to perform the first sealing; 3. The second seal 5 abuts against the upper surface of the inclined transmission section 22 by facing downward, and the inclined transmission section 22 is clamped by the support plate 11 and the second seal 5 to perform the second sealing; 4. The first seal 4 has a high-strength sealing effect, and the second seal 5 has a sealing reinforcement effect. The combined sealing of the two can achieve a stable seal at the inclined transmission section 22.

[0047] Among them, the conveyor belt 2 is a runway type as a whole. Since the conveyor belt 2 is relatively long, the figure only shows the upper part of the conveyor belt 2 used for transmission, while the lower part of the conveyor belt 2 used for rotation and the rollers, motors and other structures used to drive the conveyor belt 2 to move are not shown through the view.

[0048] Preferably, the first seal 4 in the present embodiment is located on the side of the second seal 5 toward the main transmission section 21, so that the material on the conveyor belt 2 is first sealed by the first seal 4 with high strength sealing. Among them, since the inclination direction of the first seal 4 is toward the main transmission section 21, the material and dust are easy to move toward the main transmission section 21 under the action of gravity after contacting the first seal 4, so that the sealing effect is better. In addition, the kinetic energy of the dust and material that crosses the first seal 4 is relatively small, so that the second seal 5 can effectively limit the escape of dust and material, and the second seal 5 only needs a small abutting force to eliminate the gap, so that the friction resistance is small and not easy to wear.

[0049] Preferably, the second sealing member 5 and the inclined transmission section 22 in this embodiment are in line contact, so that the contact area is minimized.

[0050] In addition, the frame 1 in this embodiment is located below the main transmission section 21 and has a plurality of support rollers 12 arranged along the length direction of the main transmission section 21. The axial direction of the support rollers 12 is the same as the width direction of the main transmission section 21, and both ends of the support rollers 12 are rotatably mounted on the frame 1 by means of bearings or the like.

[0051] Therefore, for the main transmission section 21 that mainly bears the gravity of the transmitted material, a rolling support roller 12 is used to support it so as to improve the smoothness of the transmission of the conveyor belt 2.

[0052] In addition, the dust cover 3 in this embodiment is provided with side covers 6 on both sides of the width of the conveyor belt 2. The side covers 6 and the dust cover 3 are combined to form a built-in chamber 61. The conveyor belt 2 and the dust chamber 31 are located in the built-in chamber 61, so that under the action of the built-in type, the dust and materials diffused out of the dust chamber 31 will be restricted by the built-in chamber 61 to prevent the dust from diffusing outward, thereby further improving the dust prevention effect.

[0053] Among them, the built-in chamber 61 includes an upper chamber 611 and a lower chamber 612; the support roller 12, conveyor belt 2, support plate 11, dust cover 3 and other structures are all arranged in the upper chamber 611, so that the space through the lower chamber 612 can prevent scattered materials and diffused dust from accumulating and affecting the operation of the conveyor belt 2.

[0054] In addition, the side cover 6 is provided with an inspection opening 63 and a flip door 7 for opening and closing the inspection opening 63 in the lower chamber 612, and a connecting hinge 8 is provided between the upper side of the flip door 7 and the side cover 6; the flip door 7 flips upward to open the inspection opening 63, and flips downward to close the inspection opening.

[0055] Specifically, the connecting hinge 8 in this embodiment includes a first leaf 81, a second leaf 82, and a locking plug 83, wherein the first leaf 81 and the side cover 6 are fixedly connected, and the second leaf 82 and the flip door 7 are fixedly connected by bolts, wherein first sleeves 811 are provided at both ends of the length of the lower side of the first leaf 81, and a second sleeve 821 is provided on the upper side of the second leaf 82 and between the first sleeves 811, and the number of the locking plug 83 is two, and each locking plug 83 is slidably provided on the second sleeve In 821, each second sleeve 821 is inserted into the corresponding first sleeve 811 by sliding to realize the hinged connection or disengagement of the first page 81 and the second page 82 to realize the separation of the first page 81 and the second page 82. In addition, a control handle 831 is provided on the locking rod 83 to make the locking rod 83 L-shaped. The lower end of the second sleeve 821 is provided with a travel groove 822 extending along the axial direction of the second sleeve 821, and the control handle 831 extends downward from the second sleeve 821 through the travel groove 822.

[0056] Therefore, when the connecting hinge 8 is in the assembled state, the movement of the control handle 831 drives the locking rod 83 in the second sleeve 821 to slide, and the locking rod 83 escapes from the first sleeve 811 and contacts the hinge of the flip door 7 and the side cover 6, so that the flip door 7 can be disassembled to facilitate entry and exit of the built-in chamber 61 for inspection and cleaning.

[0057] In addition, a locking spring 84 for returning the locking rod 83 to the first sleeve 811 is disposed in the second sleeve 821 , so that the locking rod 83 is stably inserted in the first sleeve 811 under the action of the locking spring 84 .

[0058] Among them, in this embodiment, a partition 823 is provided in the second sleeve 821, and the number of locking springs 84 is two. The two locking rods 83 are located on both sides of the partition 823, and the two locking springs 84 are located on both sides of the partition 823, so that the locking rods 83 and locking springs 84 on both sides can be controlled separately to carry out disassembly and assembly with the first sleeve 811.

[0059] Preferably, one end of the locking rod 83 facing the first sleeve 811 is arranged at a chamfered angle, so that the locking rod 83 can be inserted into the first sleeve 811 more smoothly.

[0060] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
