Technical Field

[0001] The utility model relates to the field of tea processing and transportation, in particular to a leakage-proof material conveying device. Background Art

[0002] The picked fresh tea leaves generally go through processes such as withering, rolling, fermentation and drying, and the tea leaves are usually transported between processes by conveyors. For example, the elevator used for tea screening and transportation receives the tea leaves processed in the previous step at the bottom, and transports the tea leaves obliquely upward with the corrugated baffle skirt, which can prevent leakage and make the tea leaves fall into the hopper screening machine.

[0003] At present, tea powder will be formed in the process of tea processing, and it contains a certain amount of moisture. When transported by the elevator, it will adhere to the conveyor belt and the inner wall of the machine body parts, and needs to be cleaned regularly to avoid affecting the elevator transportation. However, the hopper that mainly receives the tea is generally fixedly connected to the machine body, and the discharge end of the hopper is very close to the conveying part of the machine body, which makes it very inconvenient to clean the inside of the hopper and the discharge end.

[0035] See also Figure 1-5 A leakage-proof material conveying device includes a lifting component 1, a connecting component 2, a supporting arm 3, a material receiving hopper 4 and a limiting component 5. The connecting component 2 includes a plug-in portion 21 symmetrically arranged on the lifting component 1, a positioning piece 22 is arranged on the plug-in portion 21, and a supporting platform 23 located below the positioning piece 22 is arranged on the plug-in portion 21. The supporting arm 3 can move along the plug-in portion 21, the material receiving hopper 4 is arranged between the supporting arms 3, and the limiting component 5 is arranged on the lifting component 1 and is located outside the discharge port of the material receiving hopper 4.

[0036] The prior art tea screening equipment generally uses an elevator for feeding and conveying. The elevator conveyor belt is provided with a corrugated baffle skirt to block the lateral movement of the tea leaves during the tea lifting and conveying process, and prevent the tea leaves from falling between the conveyor belt and the equipment body to prevent leakage.

[0037] Based on the above, in this embodiment, the support arm 3 is inserted into the combination of the connecting component 2, and the receiving hopper 4 is inserted into the limiting component 5 through the lower material port and placed on the lifting component 1. When the docking hopper 4 is cleaned, the support arm 3 can be pulled to move along the plug-in portion 21 to drive the receiving hopper 4 to leave the limiting component 5. When the support arm 3 hits the positioning piece 22, the support arm 3 can be lowered onto the support platform 23, so that a larger gap is formed between the receiving hopper 4 and the lifting component 1. The lower material port of the receiving hopper 4 is grasped and rotated in the direction away from the lifting component 1 to expose the lower material port for cleaning, which is convenient for the staff to clean.

[0038] See also Figure 1-5 The plug-in portion 21 includes a guide plate 211 symmetrically arranged on the same side of the lifting assembly 1 , and a connecting plate 212 is arranged on the opposite side of the guide plate 211 , and a fixing member 213 is arranged on the connecting plate 212 .

[0039] The receiving hopper 4 is arranged at the insertion and plug-in portion 21 of the support arm 3, and a guide plate 211 which is an L-shaped long plate is symmetrically installed on the lifting assembly 1 to form a middle channel for movement. The support arm 3 is inserted into the channel, and at the same time, the opposite side of the guide plate 211 is combined with a fixing member 213 through a connecting plate 212. The fixing member 213 which is preferably a bolt group draws the connecting plate 212 toward the middle to reinforce the guide plate 211 forming the channel to prevent the support arm 3 from expanding the channel due to movement.

[0040] Based on the fact that the support arm 3 can move in the channel, one end of the positioning member 22 of this embodiment is connected to the connecting plate 212, and the other end of the positioning member 22 is connected to the connecting plate 212 on the other side. The support arm 3 includes a support rod 31 arranged between the guide plates 211, and a sliding protrusion 32 is arranged on the support rod 31. The sliding protrusion 32 is located between the connecting plates 212, and the support platform 23 is arranged on the connecting plate 212, and the support platform 23 is located below the support rod 31.

[0041] The support rod 31 moves between the guide plates 211, and the sliding protrusion 32 moves between the connecting plates 212, and is closed by the concave-shaped positioning piece 22 between the ends of the connecting plates 212. When the support rod 31 is pulled out from between the guide plates 211, the sliding protrusion 32 remains stationary in the positioning piece 22, and the support rod 31 is restricted and positioned. Finally, the support rod 31 is placed on the support platform 23 to determine the separation distance between the receiving hopper 4 and the lifting assembly 1.

[0042] Taking into account that the receiving hopper 4 is installed by plugging the support rod 31 and the guide plate 211, a stop block 214 is provided between the guide plates 211 in this embodiment, and the stop block 214 abuts against the support rod 31. The distance between the guide plates 211 is limited by the combination of the connecting plate 212 and the fixing member 213, and the stop block 214 placed between the guide plates 211 can be indirectly fixed, thereby limiting the insertion distance of the support rod 31, and at the same time supporting the support rod 31, and installing the support rod 31 in cooperation with the guide plate 211.

[0043] See also Figure 1-5 The limiting assembly 5 includes a pressing plate 51 and a cover plate 52, both of which are arranged on the lifting assembly 1, the pressing plate 51 is located above the discharge port of the receiving hopper 4, and the cover plate 52 is located below the discharge port of the receiving hopper 4.

[0044] When the receiving hopper 4 is inserted into the connecting assembly 2 along with the supporting arm 3 and close to the lifting assembly 1 , the material outlet of the receiving hopper 4 is inserted between the pressing plate 51 and the cover plate 52 . Meanwhile, the receiving hopper 4 is restricted by the pressing plate 51 and the cover plate 52 , and the receiving hopper 4 is fixed on the lifting assembly 1 .

[0045] Since the tea leaves are discharged to the lifting assembly 1 through the receiving hopper 4, the fallen tea leaves may directly fall along the conveying part of the lifting assembly 1 and fall to the ground. Therefore, a discharge port is provided on the cover plate 52 of this embodiment, and a switch door is provided on the discharge port. The cover plate 52 is installed at the bottom of the conveying part of the lifting assembly 1 to collect the fallen tea leaves. At the same time, a flippable switch door is provided to clean out the fallen tea leaves inside and pour them into the receiving hopper 4 to fall into the lifting assembly 1 for transportation.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
