[0040] Please see attached Figure 1-5 In one embodiment of the present invention, a tea fruit picking structure 10 includes a fixed plate 110, a first driving mechanism 120, a rotating wheel group, and a picking cage group 140, and the rotating wheel group is arranged on the fixed plate 110. First of all, it should be noted that the tea fruit picking method in the prior art is usually manual picking, which is labor-intensive, time-consuming, labor-intensive, and inefficient; there is also a method of holding the fruit tree with a picking device and using vibration to shake the tea fruit off, and then collecting it, but this method is more troublesome when holding the fruit tree, and it is more harmful to the tree trunk, and the fruit is shaken off and scattered all over the ground. If a cloth is set up under the fruit tree to collect the fallen tea fruits, it is also time-consuming and labor-intensive to set up. The present application solves the above-mentioned defects by providing a tea fruit picking structure 10 and a tea fruit picking machine 20. The details are as follows:

[0041] The picking cage group 140 includes two picking cage units which are arranged side by side in the horizontal direction and have the same rotation direction, and the picking cage unit includes a cage body 141, a transmission gear 142 arranged at the top of the cage body 141, an auger shaft 143 built into the cage body 141, and a transmission wheel 144 sleeved on the top of the auger shaft 143, and the transmission wheel 144 is installed above the fixed plate 110; the fixed plate 110 has a chamber for installing the transmission gear 142, the transmission gear 142 is arranged in the chamber and is circumferentially trasmissively arranged, and the bottom of the fixed plate 110 is also provided with a through hole for the auger shaft 143 to pass through; the cage body 141 has a feeding space for sucking in oil tea fruit branches.

[0042] Specifically, the picking cage group 140 is used to pick the oil-tea fruit. It is arranged side by side in the horizontal direction. When it rotates, it breaks the branches of the oil-tea fruit and squeezes the oil-tea fruit into another picking cage unit. Each picking cage unit includes a cage body 141, a transmission gear 142 arranged at the top of the cage body 141, an auger shaft 143 built into the cage body 141, and a transmission wheel 144 sleeved on the top of the auger shaft 143, and the transmission wheel 144 is installed above the fixed plate 110, wherein the transmission gear 142 is used to drive the cage body 141 to rotate, and the auger shaft 143 is used to collect the tea fruits squeezed into the cage body 141 and slide them down in an orderly manner along the track of the auger shaft 143, and the transmission wheel 144 is used to drive the auger shaft 143 to rotate; the fixed plate 110 is used for fixing and installing the picking unit, and the fixed plate 110 has a chamber (not shown in the figure), and the chamber is used for installing the transmission gear 142, but does not limit the rotation of the transmission gear 142 in the circumferential direction. Since the transmission wheel 144 is installed above the fixed plate 110, a through hole for the auger shaft 143 to penetrate is required to be opened at the bottom of the fixed plate 110;

[0043] Among them, the outer side of the cage body 141 is surrounded by multiple vertically extending columns 221 and the interior of the cage body 141 to form a feeding space, and the feeding space is used to accommodate oil-tea fruits and tree branches. After the oil-tea fruits enter the track of the auger shaft 143, they slide down through the track of the auger shaft 143, and the tree branches fall from the outside after rotation.

[0044] The rotating wheel group includes two synchronous wheels 130 arranged on both sides of the picking cage group 140, the synchronous wheel 130 includes an upper synchronous pulley 131 and a lower gear 132, the lower gear 132 and the upper synchronous pulley 131 are fixedly connected, the upper synchronous pulley 131 and the transmission wheel 144 are connected by a transmission belt 150, and each lower gear 132 is meshed with one of the transmission gears 142; the driving end of the first driving mechanism 120 is fixedly connected to one of the transmission wheels 144.

[0045] In detail, the rotating wheel group (not shown) is used to drive the cage body 141 to rotate, and includes two synchronous wheels 130 relatively arranged on both sides of the picking cage group 140, and the synchronous wheel 130 includes an upper synchronous belt wheel 131 and a lower gear 132. The lower gear 132 is driven to rotate by the upper synchronous belt wheel 131. The two upper synchronous belt wheels 131 and the transmission wheel 144 are distributed in a quadrilateral and are connected by a transmission belt 150. This means that the first driving mechanism 120 drives one of the upper synchronous belt wheels 131 to rotate. The synchronous pulley 131 rotates, and under the action of the transmission belt 150, the two upper synchronous pulleys 131 and the transmission wheel 144 can be driven to rotate synchronously at the same time, thereby driving the lower gear 132 to rotate. Since the lower gear 132 is engaged with one of the transmission gears 142, one of the cage bodies 141 will be driven to rotate under the rotation of the transmission gear 142, and the other lower gear 132 is also engaged with the other transmission gear 142, so that the two cage bodies 141 can rotate in the same direction.

[0046] Among them, the first driving mechanism 120 drives the transmission wheel 144 to rotate, and drives the transmission wheel 144 and the upper synchronous pulley 131 to rotate through the transmission belt 150 at the same time, the upper synchronous pulley 131 drives the lower gear 132 to rotate, and the lower gear 132 drives the transmission gear 142 to rotate, thereby driving the cage body 141 to rotate, and the two cage bodies 141 rotating in the same direction squeeze the oil tea fruits into the feeding space to pick and collect the oil tea fruits.

[0047] It is worth noting that the driving end of the first driving mechanism 120 is fixedly connected to one of the transmission wheels 144, and the first driving mechanism 120 drives the transmission wheel 144 to rotate, and the transmission wheel 144 and the upper synchronous pulley 131 connected together via the transmission belt 150 rotate synchronously. At this time, the transmission wheel 144 directly drives the auger shaft 143 to rotate, and the upper synchronous pulley 131 drives the lower gear 132 to rotate, and the lower gear 132 drives the transmission gear 142 to rotate, thereby driving the cage body 141 to rotate. Due to the gear meshing transmission, the rotation direction of the cage body 141 is opposite to that of the auger shaft 143. Therefore, the two cage bodies 141 rotating in the same direction squeeze the oil tea fruits into the feeding space, and the auger shaft 143 rotating in the opposite direction causes the collected oil tea fruits to slide along the channel 2811 to complete the picking.

[0048] It is worth mentioning that since the branches of the oil tea tree itself also need to be pruned, there is no need to worry about damage to the branches. This is different from the existing technology that uses vibration to harm the tree trunk.

[0049] As a preferred embodiment of the present invention, the cage body 141 includes a cage body 1411 and a plurality of reinforcing bars 1412 arranged at intervals along the circumference of the cage body 1411, and the reinforcing bars 1412 are wavy. It should be noted that the reinforcing bars 1412 are used to squeeze the oil tea fruit into the feeding space. The plurality of reinforcing bars 1412 are arranged at intervals along the circumference of the cage body 1411, and the oil tea fruit is inserted into the feeding space through the interaction between two adjacent reinforcing bars 1412. Since the oil tea fruit is mostly spherical or elliptical, the reinforcing bars 1412 are arranged in a wavy shape to facilitate the oil tea fruit to enter better.

[0050] As a preferred embodiment of the present invention, a protective cover 160 is further included, and the protective cover 160 is disposed on the top of the fixing plate 110, and the protective cover 160 is fixedly connected to the fixing plate 110. It can be understood that the protective cover 160 can be provided in a rectangular parallelepiped shape to cover the top of the fixing plate 110 to protect the components disposed above the fixing plate 110 from damage and influence.

[0051] Furthermore, the spacing between two adjacent reinforcing bars 1412 is 30 mm to 40 mm. It is worth noting that the spacing between two adjacent reinforcing bars 1412 can be selected by those skilled in the art according to the diameter of the oil-tea fruit, and preferably, can be set to 30 mm to 40 mm.

[0052] The present invention also provides a tea fruit picking machine 20, comprising a picking machine 210, an arm extension mechanism, and the tea fruit picking structure 10 as described above; wherein the picking machine 210 comprises a picking machine body 211, a control mechanism 212 and a starting device 213 for providing power, wherein the control mechanism 212 is arranged in the middle of the picking machine body 211, and the starting device 213 is fixed to the tail end of the picking machine body 211; the arm extension mechanism is used for adjusting the position of the tea fruit picking structure 10, and comprises A horizontal rotation adjustment mechanism 220, a vertical adjustment mechanism 230 and a telescopic adjustment mechanism 240, wherein the horizontal rotation adjustment mechanism 220 is fixed to the front end of the picking machine body 211, the vertical adjustment mechanism 230 is vertically rotatable around the top of the horizontal rotation adjustment mechanism 220, the telescopic adjustment mechanism 240 is fixed to the top of the vertical adjustment mechanism 230 and is telescopically arranged along its own extension direction, and the oil tea fruit picking structure 10 is fixedly connected to the telescopic adjustment mechanism 240.
