Detailed implementation manners

[0016] The following are specific embodiments of the present invention. In combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0017] The side-turning structure of the tea collection box of this tea picking machine is applied to a tea box for storing tea. The tea box includes a bracket 1, a frame 2, a box body 3 and a cover plate 4. The front end of the bottom of the box body 3 is rotatably arranged on the frame 2, the frame 2 is vertically movable on the bracket 1, an outlet for pouring out tea is provided at the front end of the box body 3, and the cover plate 4 is rotatably hung at the outlet of the box body 3.

[0018] As Figures 1 to 4 shown, the side-turning structure of the tea collection box of this tea picking machine includes a lifting component for changing the height position of the frame 2 relative to the bracket 1, a tilting component for changing the tilting angle of the box body 3 relative to the frame 2, and an opening plate component for changing the closing degree of the cover plate 4 relative to the outlet.

[0019] When the tea box in the box body 3 is full of tea and needs to be poured out, first, the box body 3 needs to be lifted to a sufficient height through the lifting component, so that objects such as collection bags can be placed below the box body 3 to complete the collection. Then, in order to pour out the tea, the tilting component is required to realize the side-turning and pouring function of the box body 3. At the same time, the cover plate 4 cannot always cover the outlet of the box body 3, otherwise the tea cannot come out. Then, the opening plate component is used to change the opening and closing angle of the cover plate 4 so that the tea can be poured out.

[0020] The tilting component includes a tilting fixed block 5 fixedly arranged on the frame 2 and a tilting moving block 6 fixedly arranged on the box body 3. A driving hydraulic cylinder 7 and a first rocker 8 are coaxially rotatably arranged on the tilting fixed block 5. A second rocker 9 is rotatably arranged on the tilting moving block 6. The ends of the first rocker 8 and the second rocker 9 are rotatably connected, and the end of the piston rod of the driving hydraulic cylinder 7 is rotatably connected to the middle of the second rocker 9.

[0021] The functions of the first rocker 8 and the second rocker 9 are to make the positional relationship of the entire tilting component on the frame 2 and the box body 3 become uniquely fixed. From a mechanical perspective, it is limited to one degree of freedom or a kinematic pair. Then, through the pressing action of the driving hydraulic cylinder 7, the second rocker 9 is stressed to change the positional relationship. However, because the entire tilting component itself only has one degree of freedom, no matter the piston rod of the driving hydraulic cylinder 7 extends or retracts to any position point, the state of the box body 3 relative to the frame 2 is unique, which has good reliability and can change the tilting position of the box body 3.

[0022] In an ideal state, the cover plate 4 can be freely hung relative to the box body 3. Because after the box body 3 is tilted, the cover plate 4 will automatically hang down to expose the outlet. And when the box body 3 is placed upright, the cover plate 4 will be perpendicular to the ground due to the action of gravity, so the box body 3 can also cover the outlet. However, all of these are in an ideal state. Because the tea leaves in the box body 3 will press against the cover plate 4 from the side after having a certain weight, which causes the cover plate 4 to open. Moreover, due to the unevenness of the ground, if the cover plate 4 is only hung without being limited during the stepping process of the tea picking machine, it will vibrate and open and close, resulting in the tea leaves falling out from the outlet. Therefore, an opening plate assembly is still needed to controllably open and close the cover plate 4.

[0023] The opening plate assembly includes a first fixing body 10 fixedly arranged on the frame 2, a second fixing body 11 fixedly arranged on the cover plate 4, an opening plate chain 12, and an opening plate reversing wheel set. The two ends of the opening plate chain 12 are respectively fixed on the first fixing body 10 and the second fixing body 11. The opening plate reversing wheel set is arranged on the frame 2 and the box body 3 to ensure that the opening plate chain 12 is always in a taut state.

[0024] Because the cover plate 4 needs to change its angle relative to the box body 3, the two ends of the opening plate chain 12 cannot be fixed on the box body 3 and the cover plate 4. Since the opening plate chain 12 needs to be in a taut state to play its traction benefit function, if the opening plate chain 12 is fixed on the box body 3 and the cover plate 4 and is taut, then the opening plate chain 12 cannot play the function of opening and closing.

[0025] In this regard, in this design, the two ends of the opening plate chain 12 are fixed on the cover plate 4 and the frame 2. Because the box body 3 needs to operate relative to the frame 2, and the cover plate 4 needs to operate relative to the box body 3, so both the cover plate 4 and the frame 2 are movable relative to the box body 3. Then the box body 3 can act as an intermediate medium. By reasonably designing the opening plate reversing wheel set and changing the path direction of the chain, the chain can pull the cover plate 4 to change its position while being taut.

[0026] The opening plate reversing wheel set includes a first reversing sprocket 13 rotatably arranged on the frame 2, a second reversing sprocket 14 rotatably arranged on the box body 3, a third reversing sprocket 15 rotatably arranged on the frame 2, and a fourth reversing sprocket 16 rotatably arranged on the box body 3. The opening plate chain 12 passes through and is hung on the first reversing sprocket 13, the second reversing sprocket 14, the third reversing sprocket 15, and the fourth reversing sprocket 16 in sequence.

[0027] The function of the first reversing sprocket 13, the second reversing sprocket 14, the third reversing sprocket 15 and the fourth reversing sprocket 16 is to allow the opening chain 12 to be in a tensioned state, and then through the limitation of the length of the opening chain 12 itself, after the box body 3 is tilted relative to the frame 2, the cover plate 4 will also be opened due to its own gravity, but because of the tensioning and limiting effect of the opening chain 12, the degree of opening of the cover plate 4 is fixed, which is a pop-up process, and the main purpose of this design is still for the closing function of the cover plate 4. When the tilting assembly aligns the box body 3 relative to the frame 2, the opening chain 12 will pull the cover plate 4 tightly, so that the cover plate 4 will not be opened freely, thereby playing a reliable blocking function.

[0028] The opening plate assembly further comprises a telescopic rod 17, and the two ends of the telescopic rod 17 are respectively rotatably arranged on the box body 3 and the cover plate 4. The telescopic rod 17 provides a reliable function, ensuring that the cover plate 4 is stable and slow in the process of opening or closing.

[0029] The lifting assembly includes a lifting drive motor 18 fixedly arranged above the bracket 1, a fixed sliding sprocket 19 fixedly sleeved on the end of the output shaft of the lifting drive motor 18, a lifting fixed body 20 fixedly arranged below the bracket 1, and a lifting chain 21 with one end fixedly arranged on the lifting fixed body 20 and hung on the fixed sliding sprocket 19, and the other end of the lifting chain 21 is fixedly connected to the frame 2. After the lifting drive motor 18 is operated, the fixed sliding sprocket 19 rotates and pulls the lifting chain 21 through the fixed sliding sprocket 19 to realize the change of the height position of the frame 2 relative to the bracket 1.

[0030] During the lifting process, the lifting drive motor 18 drives the entire frame 2 to lift, and only after lifting can the box 3 pour out the tea leaves from top to bottom. Because the box 3 is originally in a bottom-handed position, in order to collect the tea leaves immediately from the bottom after pouring out the tea leaves in the box 3, the box 3 needs to have a lifting function.

[0031] from Figures 1 through 4 The present side-turning structure embodies the entire process of pouring out tea leaves in one process. First, the box body 3 needs to be lifted to a sufficiently high height along with the frame 2, and then a packaging bag for collecting the poured tea leaves is placed at the tail of the tea picking machine. Then, the tea leaves automatically complete the opening function of the cover plate 4 by flipping the inclination angle of the box body 3 relative to the frame 2, and then the tea leaves can fall out of the outlet into the packaging bag.

[0032] It should be understood that in the claims and description of the present invention, all "including..." should be understood as an open-ended meaning, that is, its meaning is equivalent to "at least contains...", and should not be understood as a closed meaning, that is, its meaning should not be understood as "only includes...".
