DETAILED DESCRIPTION

[0037] In order to make the content of the utility model more easily be clearly understood, the following according to specific embodiment and combining with the drawings, the utility model is further explained in detail.

[0038] Example 1:

[0039] Please refer to Figures 1 to 4 The embodiment provides a kind of unloading valve assembly, including: discharge port 1, the discharge pipe body 2 of being located in the outer side of discharge port 1, and the plug for blocking discharge port 1 and the movable carrier 3 for fixing plug are located in discharge pipe body 2;Movable carrier 3 is also connected with the drive structure for driving the rotating motion of this movable carrier 3 around its one side edge;Discharge pipe body 2 is formed with discharge port 21, and discharge pipe body 2 has hollow cavity 22 for accommodating movable carrier 3 and plug.Theoretically speaking, the shape of discharge pipe body 2 here can be straight pipe also can be other shape pipe body, for this from the angle of simplifying processing technology, the embodiment is explained with the case of using straight pipe.

[0040] Next, an optional case is described in detail in conjunction with the drawings, and the drive structure includes at least one pressing rod 4 suitable for pushing the plug from the side away from discharge port 1, connecting rod 5 movably connected with movable carrier 3, rotating shaft 6 for simultaneously driving at least one pressing rod 4 and connecting rod 5 to rotate, and power unit for driving rotating shaft 6 to rotate;Wherein movable carrier 3 is provided with sliding groove 31 suitable for sliding cooperation with connecting rod 5.Rotating shaft 6 is rotatably connected with the side wall of discharge pipe body 2, and the axial direction of rotating shaft 6 is perpendicular to the depth direction of cavity 22 of discharge pipe body 2, and at least one pressing rod 4 and connecting rod 5 can rotate in cavity 22.From the stability of the pushing action on the plug, the drive structure includes two pressing rods 4, which can respectively push the plug at different positions.When a pair of pressing rods 4 pushes the plug to block discharge port 1, the pair of pressing rods 4 is respectively located on both sides of movable carrier 3.

[0041] Based on the above, when the rotating shaft 6 rotates in the first direction, the rotating shaft 6 drives the at least one pressing rod 4 to rotate in a direction away from the discharge port 1, and the connecting rod 5 moves in the positive direction along the sliding groove 31, so that the plug rotates in a direction away from the discharge port 1 to release the plugging of the discharge port 1; when the rotating shaft 6 rotates in the second direction opposite to the first direction, the rotating shaft 6 drives the at least one pressing rod 4 to rotate in a direction close to the discharge port 1, and the connecting rod 5 moves in the reverse direction along the sliding groove 31, so that the plug rotates in a direction close to the discharge port 1 to achieve the plugging of the discharge port 1. That is, in the two different cases of plugging and unplugging of the discharge port 1 by the plug, the directions of movement of the rotating shaft 6, the pressing rod 4 and the connecting rod 5 are opposite. The end of the connecting rod 5 away from the rotating shaft 6 can be movably connected to the sliding groove 31 through a shaft pin.

[0042] In addition, it should be further pointed out that in a specific optional embodiment, the line connecting the pair of pressing rods 4 can be parallel to the axis of the rotating shaft 6, and each pressing rod 4 is formed with a central angle of 45-90° with respect to the axis of the rotating shaft 6 with respect to the connecting rod 5. In this structure, when it is necessary to release the plugging state of the plug to the discharge port 1, the pressing rod 4 can gradually move away from the plug until completely leaving the plug, so that the angle of rotation of the plug with respect to the discharge port 1 is sufficient for the discharge of the material, and the connecting rod 5 is used to prevent the plug from rotating too much and hitting the rotating shaft 6. It is found through actual test that when the angle of rotation of the plug with respect to the discharge port 1 is between 50-80°, both the discharge of the material and the avoidance of hitting the rotating shaft 6 can be achieved.

[0043] It is also necessary to point out that regarding the shape of the pressing rod 4, in an optional case, the pressing rod 4 includes a straight rod-shaped body 41 fixedly connected to the rotating shaft 6 and a hook head 42 provided at one end of the straight rod-shaped body 41 away from the rotating shaft 6; wherein the hook head 42 is bent towards the side of the plug with respect to the straight rod-shaped body 41. The pressing rod 4 of this structure requires relatively small space for rotation compared to the pressing rod 4 which is entirely straight, so that the occupancy rate of the cavity 22 space of the discharge pipe body 2 can be reduced.

[0044] Moreover, it also needs to be explained that, in order to improve the reliability of the plug for the plugging state formed by the discharge port 1, first of all, an annular positioning member 7 is arranged on the outer side edge of the discharge port 1. Secondly, the plug adopts a T-shaped structure; more specifically, the plug includes a main body part 201 for plugging the discharge port 1 and an extension part 202 arranged on the side end of the main body part 201 away from the discharge port 1 for matching with the positioning member 7; a sealing ring 8 is arranged between the extension part 202 and the positioning member 7. Moreover, the size of the extension part 202 is greater than that of the main body part 201, and for the sealing ring 8 here, it can be fixed on the positioning member 7 itself, so that whether the plug rotates relative to the discharge port 1 or not will not affect the sealing ring 8. As for the movable carrier 3 of the present embodiment, the overall size and shape thereof do not need to be the same as that of the plug, for example, the length size of the movable carrier 3 can be the same as that of the plug, while the width size can be smaller than that of the plug, at this time, only by arranging the movable carrier 3 at the middle position of the width size of the plug, the plug can be smoothly driven to move by the movable carrier 3, and based on this, the extension direction of the chute 31 can be along the length direction of the movable carrier 3.

[0045] Next to be explained is that, for the power unit for driving the rotation of the rotating shaft 6, as long as it can drive the rotating shaft 6 to make forward rotation and reverse rotation in theory, it meets the use requirement of the present embodiment, here an optional case is taken as an example, the power unit includes a worm wheel 92 connected with one end of the rotating shaft 6, a worm gear 91 in transmission cooperation with the worm wheel 92, and a driver for driving the worm gear 91 to rotate. Wherein the driver adopts a manual rotating wheel 93 or a motor. The power unit here is arranged outside the discharge pipe body 2, and is connected with the end of the rotating shaft 6 which penetrates through the side wall of the discharge pipe body 2 and extends to the outside of the discharge pipe body 2, so that the power unit does not need to be built-in in the discharge pipe body 2, and will not interfere with the material discharging process.

[0046] In summary, for the present embodiment, the plug is relatively opened and closed in a rotating manner relative to the discharge port 1, which can avoid interference with the discharge process in the front of the discharge port 1, thereby improving the applicability to different drying kettles 10.

When it is a horizontal drying machine, the discharge port 1 is arranged on the side wall of the vertical drying machine facing the ground, and the discharge port 21 of the discharge pipe body 2 is arranged on the side wall of the discharge pipe body 2 facing the ground, so that the discharge port 1 and the discharge port 21 are approximately straight, at this time, the rotation direction of the plug relative to the discharge port 1 is to the left side or the right side (perpendicular to the ground), so that the plug does not interfere with the material discharge path, and for the drying machine based on this condition, the driver can be selected as a motor or a manual rotating wheel 93, which is convenient to use, and the drawings of the embodiment only take the case of the horizontal drying machine as an example.
