[0032] Figure 1 It is a schematic diagram of the overall structure of the device provided by an embodiment of the present invention; Figure 2 The embodiment of the present invention provides Figure 1 A magnified schematic diagram of point A; Figure 3 The embodiment of the present invention provides Figure 1 An enlarged schematic diagram of point B; Figure 4 The embodiment of the present invention provides Figure 1 An enlarged schematic diagram of point C; Figure 5 The embodiment of the present invention provides Figure 1 An enlarged schematic diagram of point D; Figure 6 The embodiment of the present invention provides Figure 1 An enlarged schematic diagram of point E; Figure 7 is a schematic side view of the entire device provided by an embodiment of the present invention; Figure 8 Schematic diagram of the bottom frame structure provided by an embodiment of the present invention. Figures 1 to 8 The fruit collecting device shown in the figure comprises: a bottom frame 1, a fruit collecting device 2, a first leak-proof elastic rope 3 and a second leak-proof elastic rope 4. The bottom frame 1 is a box-shaped structure with an open top. The bottom frame 1 comprises a bottom plate 11 and a side plate 12. The side plate 12 is arranged at an obtuse angle to the bottom plate 11. A slot 121 is provided on the side plate 12. The first leak-proof elastic rope 3 is arranged on the side plate 12 and covers the slot 121. The fruit collecting device 2 comprises an opening and closing rod 21, a support rod 22 and a fruit collecting cloth 23. The fruit collecting device 2 is arranged on the bottom frame 1 in an inverted cone shape, two opening and closing rods 21 are provided, and at least one support rod 22 is provided. The opening and closing rod 21 and the support rod 22 are arranged on the bottom frame 1, and the fruit collecting cloth 23 is sleeved on the opening and closing rod 21 and the support rod 22. The end of the opening and closing rod 21 close to the bottom frame 1 is provided with a bending section 213 matching the slot 121, and a second leakage-proof elastic rope 4 is arranged in the bending section 213. One end of the opening and closing rod 21 is rotatably connected to the bottom frame 1.

[0033] For example, in the embodiment of the present invention, multiple rows of symmetrical circular holes are provided on both sides of the slot hole 121, and the first leak-proof elastic rope 3 is installed in the circular holes so that the first leak-proof elastic rope 3 covers the slot hole 121. Figure 2As shown, the end of the opening and closing rod 21 close to the bottom frame 1 has a bent section 213, and a second leak-proof elastic rope 4 is arranged at the notch of the bent section 213. The opening and closing rod 21 and the support rod 22 are arranged at an angle on the open end of the bottom frame 1, and the opening and closing rod 21 and the support rod 22 are arranged at an obtuse angle with the bottom plate 11. The fruit collecting cloth 23 is arranged on the opening and closing rod 21 and the support rod 22, forming an inverted cone structure. Place the device next to the tree trunk to be collected, rotate the opening and closing rod 21 to move the two opening and closing rods 21 away from each other, move the first leak-proof elastic rope 3 close to the trunk and squeeze it toward the trunk, so that the trunk moves to the inside of the bottom frame 1 through the slot 121, and one side of the trunk is tightly embraced by the first leak-proof elastic rope 3, rotate the opening and closing rod 21 to bring the two opening and closing rods 21 together, and the bent sections 213 on the two opening and closing rods 21 are aligned to form a "C"-shaped recess to cooperate with the other side of the trunk, so that the other side of the trunk is tightly embraced by the second leak-proof elastic rope 4. At this time, the trunk to be collected is surrounded by the first leak-proof elastic rope 3 and the second leak-proof elastic rope 4. The fruits that fall down will fall into the fruit collecting device 2 and then fall into the bottom frame 1, so that the fruits can be collected. Due to the use of an elastic structure, the gap between the trunk and the device for clamping the trunk is filled, thereby preventing the fruits from falling outside the bottom frame 1.

[0034] The embodiment of the present invention provides a fruit collection device and method, which controls the opening and closing of an opening and closing rod 21 so that the tree trunk can smoothly enter the bottom frame 1. At the same time, the first leakage-proof elastic rope 3 is tightly embraced with one side of the tree trunk, and the second leakage-proof elastic rope 4 is tightly embraced with the other side of the tree trunk, so that the fruit can accurately enter the bottom frame 1 when being collected. The first leakage-proof elastic rope 3 and the second leakage-proof elastic rope 4 can adapt to tree trunks of different sizes and shapes and surround the tree trunks therein. Due to the use of an elastic structure, the gap between the tree trunk and the device for clamping the tree trunk is filled, thereby preventing the fruit from falling outside the bottom frame 1, which can effectively solve the problem of low compatibility in the prior art.

[0035] Optionally, a folding component 5 is provided in the middle of the opening and closing rod 21 and the middle of the support rod 22 , and both ends of the opening and closing rod 21 are hinged through the folding component 5 , and both ends of the support rod 22 are hinged through the folding component 5 .

[0036] For example, in an embodiment of the present invention, Figure 3As shown, the folding component 5 includes a first folding square tube 51, a second folding square tube 52 and a connecting piece 53. The opening and closing rod 21 and the supporting rod 22 are disconnected from the middle, and the first folding square tube 51 and the second folding square tube 52 are respectively sleeved on the two ends after disconnection, and the first folding square tube 51 and the second folding square tube 52 are respectively fixed thereon by bolts. The first folding square tube 51 and the second folding square tube 52 are connected by the connecting piece 53, and the two ends of the connecting piece 53 are respectively fixed on the first folding square tube 51 and the second folding square tube 52 by bolts. The contact area of ​​the second foldable square tube 52 is stressed, so the first foldable square tube 51 and the second foldable square tube 52 can be folded together, thereby driving the opening and closing rod 21 and the support rod 22 to fold as a whole. After folding, the overall length of the opening and closing rod 21 and the support rod 22 is shortened, thereby reducing the overall footprint of the device. In a dense fruit forest, the device is easier to move and transport. At the same time, when it is necessary to collect fruits, the foldable component 5 can be opened to increase the area of ​​the fruit collecting device 2, so that more fruits fallen from the trees can be collected, thereby improving the operation convenience of the device.

[0037] Optionally, one end of the support rod 22 is rotatably connected to the bottom frame 1 .

[0038] For example, in an embodiment of the present invention, Figure 4 As shown, the device further comprises a rotating component 6, which comprises a rotating seat 61, an articulated bolt 62, an angle wedge 63 and a pipe support 64. The rotating seat 61 is rotatably arranged at the edge of the opening surface of the bottom frame 1, and a rotating groove 65 is provided in the middle of the rotating seat 61, and the rotating groove 65 is vertically arranged. A matching hole matching the support rod 22 is provided at one end of the pipe support 64, and the support rod 22 and the pipe support 64 are interference-fitted through the matching hole. A mounting hole matching the articulated bolt 62 is provided at the other end of the pipe support 64, and the pipe support 64 is arranged in the rotating seat 61 through the mounting hole at the other end and is articulated through the articulated bolt 62. The angle wedge 63 is a wedge-shaped structure arranged at the bottom of the rotating groove 65. In a natural state, the support rod 22 contacts the inclined surface of the angle wedge 63, so that the support rod is inclinedly arranged on the bottom frame 1, thereby maintaining the overall inverted cone structure of the fruit collecting device 2. The support rod 22 is connected to the bottom frame 1 through the rotating component 6, so that the support rod 22 can rotate around one end close to the bottom frame 1. In the non-fruit collecting state, the fruit collecting device 2 can be gathered by rotating the support rod 22 and the opening and closing rod 21, thereby reducing the occupied space of the fruit collecting device 2. When the device needs to be moved, the device can be more easily moved and transported, further improving the convenience of operation of the device. One end of the opening and closing rod 21 can also be connected to the bottom frame 1 using the rotating component 6 in this embodiment.

[0039] Optionally, a cloth cover 24 is provided at one end of the opening and closing rod 21 and the supporting rod 22 away from the bottom frame 1 .

[0040] For example, in an embodiment of the present invention, Figure 5 As shown, the fruit collecting cloth 23 is sleeved on the opening and closing rod 21 and the support rod 22, and then the cloth cover 24 is sleeved on the fruit collecting cloth 23, so that the fruit collecting cloth 23 is more firmly fixed on the opening and closing rod 21 and the support rod 22, so that the fruit collecting device 2 can receive a larger number of fruits, and the fruit collecting cloth 23 will not fall off, thereby improving the operating stability of the device.

[0041] Optionally, a latch pin 211 is further included, and a latch pin hole 212 is provided at one end of the opening and closing rod 21 away from the bottom frame 1 , and both ends of the latch pin 211 are inserted into the two latch pin holes 212 .

[0042] Exemplarily, in an embodiment of the present invention, after the first leakage-proof elastic rope 3 and the second leakage-proof elastic rope 4 embrace the tree trunk, the device as a whole will be subjected to the reverse force of the tree trunk, and the reaction force will push the opening and closing rod 21 to open. At this time, by opening a latch hole 212 on the two opening and closing rods 21 and inserting a latch 211 in the two latch holes 212, the two opening and closing rods 21 are fixedly connected, so that the first leakage-proof elastic rope 3 and the second leakage-proof elastic rope 4 embrace the tree trunk more tightly, thereby further improving the operating stability of the device.

[0043] Optionally, a walking wheel 13 is provided at the bottom of the bottom frame 1 , a handle 14 is provided on the bottom frame 1 , and a universal wheel 15 is provided below the handle 14 .

[0044] For example, in the embodiment of the present invention, since the fruit collecting device 2 is an inverted cone structure as a whole, and in order to collect as many fruits as possible, the fruit collecting device 2 is generally larger, and a handle 14 is provided on the bottom frame 1, and the handle 14 extends from the bottom of the fruit collecting device 2, so that the operator can push the device conveniently, and the running wheel 13 is provided at the bottom of the bottom frame 1 so that the device can move in a straight line, and a universal wheel 15 is provided below the handle 14 to adjust the walking direction of the device. The universal wheel 15 is provided below the handle 14, and the universal wheel 15 and the running wheel 13 form a triangular structure, so that the chassis of the device is more stable, and it is more labor-saving to push the handle 14 when moving, which further improves the convenience of operation of the device. At the same time, a brake is provided on the universal wheel 15. When the device is ready to collect fruits, the first leak-proof elastic rope 3 will first be pressed against one side of the tree trunk and continue to be squeezed so that the first leak-proof elastic rope 3 will embrace the tree trunk. At this time, the tree trunk will generate a reverse force on the device. The brake provided on the universal wheel 15 can lock and fix the device to offset the reverse force generated by the tree trunk on the device, making it convenient for the operator to perform the next operation. The brake is provided on the universal wheel 15, which further improves the convenience of operation of the device.

[0045] Optionally, a fruit frame 16 is further included, and a slide rail 17 is arranged below the handle 14 , and the fruit frame 16 is slidably arranged on the slide rail 17 .

[0046] Illustratively, in an embodiment of the present invention, a slide rail 17 is provided below the handle 14 along the direction of the handle 14, and a fruit frame 16 can be slidably provided on the slide rail 17 to collect the fruits in the fruit frame 16. After the fruits are collected, the fruits in the fruit frame 16 can be directly transported out through the slide rail 17 for easy collection, without the need for an operator to manually collect the fruits in the fruit collecting device 2 for a second time, thereby saving the labor of the operator and improving the fruit collecting efficiency of the device.

[0047] Optionally, the handle 14 is connected to the side plate 12 on the bottom frame 1 opposite to the slot 121 , and a feed opening 10 is also provided on the bottom frame 1 .

[0048] For example, in an embodiment of the present invention, Figure 8 As shown, by providing a discharge port 10 on the bottom frame 1, the discharge port 10 can be connected with the inside of the fruit frame 16, and the fruits collected in the bottom frame 1 can directly fall into the fruit frame 16 through the discharge port 10, and then the fruit frame 16 full of collected fruits can be transported out through the slide rail 17. By providing the discharge port 10, the collected fruits can directly fall into the fruit frame, thereby further improving the fruit collection efficiency of the device.

[0049] Optionally, a cloth bag support bottom 18 is horizontally arranged above the universal wheel 15 , and a bag support rod 19 is provided between the handle 14 and the cloth bag support bottom 18 .

[0050] For example, in the embodiment of the present invention, the fruits are usually collected and transported by cloth bags. The bag mouth can be opened by the bag support rod 19, and the bottom of the cloth bag is placed on the cloth bag support 18. After the fruit collecting device collects a basket of fruits, the fruit frame 16 containing the fruits is transported to the top of the cloth bag by the slide rail 17. After the fruits in the fruit frame 16 are poured into the cloth bag, the fruit frame 16 returns to the bottom of the bottom frame 1 through the slide rail 17 to continue collecting the fruits. Since the storage space of the bottom frame 1 and the fruit frame 16 is limited, the continuous collection of fruits is facilitated by providing the cloth bag support 18 and the bag support rod 19, and finally the whole bag of collected fruits is packaged and transported, which further improves the fruit collection efficiency of the device.

[0051] A method for collecting fruit trees, based on the aforementioned fruit tree collection device, comprises the following steps:

[0052] Step 1: Rotate the opening and closing rods 21 to move the two opening and closing rods 21 away from each other, move the first leak-proof elastic rope 3 close to the tree trunk, and squeeze it toward the tree trunk, so that the tree trunk moves through the slot 121 to the inside of the bottom frame 1, and one side of the tree trunk is tightly embraced by the first leak-proof elastic rope 3.

[0053] Step 2: Rotate the opening and closing rods 21 to bring the two opening and closing rods 21 together, so that the other side of the tree trunk is tightly embraced by the second leak-proof elastic rope 4, and then start picking fruits.

[0054] Exemplarily, in an embodiment of the present invention, the specific steps of the collecting method are as follows: in the initial state, the folding parts 5 on the opening and closing rod 21 and the support rod 22 are in the folded state, and the opening and closing rod 21 and the support rod 22 are rotated and gathered together by the rotating part 6. At this time, the device is in the state of occupying the minimum space, and the brake on the universal wheel 15 is released, and the handle 14 is pushed to move the device among the fruit trees. When it moves to the side of the target fruit tree, the handle 14 is pushed to bring the first leakage-proof elastic rope 3 close to the trunk and squeeze it toward the trunk, so that the trunk moves through the slot 121 to the inside of the bottom frame 1, and one side of the trunk is tightly embraced by the first leakage-proof elastic rope 3. The brake on the universal wheel 15 is operated to stop the device to prevent the device from moving under the reaction force of the trunk, and the folding part 5 is operated to make the opening and closing rod 21 and the support rod 22 reach the longest state, and the rotating part 6 is controlled to make the opening and closing rod 21 and the support rod 22 rotate and open, so that the fruit collecting device 2 reaches the maximum state, the rotating part 6 is continued to control the opening and closing rod 21 to gather, the other side of the tree trunk is tightly embraced by the second leak-proof elastic rope 4, and the latch 211 is inserted into the two latch holes 212 to fix the opening and closing rod 21. At this time, the collection of forest fruits can begin, and the forest fruits fall into the bottom frame 1, and the fully collected forest fruits fall into the fruit frame 16. After the fruit frame 16 is full, the fruit frame 16 is transported to the top of the cloth bag through the slide rail 17. After the forest fruits in the fruit frame 16 are poured into the cloth bag, the fruit frame 16 returns to the position close to the bottom frame 1 through the slide rail 17 to continue collecting forest fruits. After the collection is completed, the latch 211 is pulled out, the rotating part 6 is controlled to rotate and gather the opening and closing rod 21 and the support rod 22, and the folding part 5 is operated to fold the opening and closing rod 21 and the support rod 22. At this time, the device is in the state of occupying the minimum space. After releasing the brake of the universal wheel 15, the handle 14 is continued to be pushed to move the device to the next target fruit tree for collecting fruits.
