Description

Technical Field

[0001] This utility model belongs to the field of jujube picking tools, specifically relating to a portable jujube picking device. Background Technology

[0002] Fresh jujubes are loved for their rich vitamin C content and crisp, sweet taste. However, harvesting fresh jujubes differs from harvesting dried jujubes. Dried jujubes are usually harvested after the stems have fully grown on the tree, at which point the stems are brittle and can be easily shaken off by tapping the branches with a bamboo pole. For fresh jujubes, the stems are still very tough, making it difficult to shake them off with a bamboo pole. Therefore, to solve the problem of harvesting fresh jujubes, as shown in Chinese Utility Model Patent CN202320068002.9, several teeth are set at the top of the harvesting tube. During harvesting, the harvesting tube is used to net the jujube fruit, so that the jujube fruit and the branch or branch are located on both sides of the teeth. Then, the harvesting tube is pulled to separate the jujube fruit from the branch or branch. The problems with this jujube-picking tool are as follows: when there are many jujubes caught in the picking funnel or the jujube stalks are very tough, a lot of force is needed to pull the picking tube to separate the jujubes. The inertia generated by this pulling is also significant, causing the arm to be unable to retract in time due to inertia, resulting in bumps or scratches from the branches. Furthermore, pulling the picking tube with great force also causes the branches to sway significantly, affecting the accuracy of catching the next jujube. To solve these problems, as shown in Chinese utility model patent 202423164415.0, several lower blades are set at the top of the picking tube, and a cover with several upper blades is set. The opening and closing of the cover is controlled by a hinged handle to cut the jujube stalks or stalks. However, the problem is that the opening range of the cover is limited, and due to the space occupied by the cover, the cover will collide with the jujube branches when catching the jujubes, thus failing to catch the jujubes into the picking tube. This is especially true for jujubes close to the branches, where the cover often collidees with the branches and fails to catch the jujubes. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing jujube picking devices, where the cover occupies space above the picking cylinder, preventing some jujubes from being caught and picked. This invention provides a portable jujube picking device for picking fresh jujubes.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A portable jujube-picking device includes a picker, a picking bag disposed at the bottom of the picker, and a hand-held handle disposed on one side of the picker; the picker includes a picking funnel with an open top, a plurality of jujube-holding rails disposed around the circumference of the picking funnel, a cutting mechanism sleeved on the outside of the picking funnel and rotatably connected to the picking funnel, and a drive mechanism for driving the cutting mechanism to rotate.

[0005] As a further technical solution, an arc-shaped notch is provided at the end of the picking funnel away from the hand handle, thereby forming an arc-shaped baffle on the opposite side of the arc-shaped notch; a plurality of the jujube-holding railings are evenly distributed at the arc-shaped notch; gaps are provided between the arc-shaped baffle and the end jujube-holding railings as well as between adjacent jujube-holding railings.

[0006] As a further technical solution, the cutting mechanism includes an annular base sleeved on the outside of the harvesting funnel via a bearing, and a plurality of cutting blades arranged circumferentially on the annular base. As a further technical solution, the number of cutters is equal to the number of gaps, and the cutters are positioned behind the corresponding gaps according to the rotation direction of the cutter mechanism.

[0007] As a further technical solution, the cutter is provided with a blade, and the blades of several cutters are in the same direction and are all arranged at the front of the cutter along the rotation direction of the cutter.

[0008] As a further technical solution, the height of the jujube-holding railing is at least 1 / 2 the height of the open cylinder of the harvesting funnel.

[0009] The cutter has two states. When not in operation, the cutter is located behind the corresponding gap along the direction of rotation and does not occupy the position of the adjacent gap behind it. When in operation, the cutter rotates, and its rotation path covers at least one gap in front of it.

[0010] As a further technical solution, the driving mechanism includes a first protrusion disposed on an annular base, a second protrusion disposed on a hand handle, a driving rod slidably disposed on the second protrusion, and a transmission rod connecting the driving rod and the first protrusion, wherein the two ends of the transmission rod are respectively hinged to the driving rod and the first protrusion.

[0011] As a further technical solution, a positioning stop bar is also provided on the side wall of the harvesting funnel.

[0012] As a further technical solution, an annular protrusion is provided at one end of the hand handle near the transmission rod, and a return spring is provided between the annular protrusion and the second protrusion, and the return spring is sleeved on the hand handle.

[0013] As a further technical solution, an operating handle or traction rope is provided at the end of the drive rod away from the transmission rod.

[0014] As a further technical solution, a hand grip is provided at the end of the hand handle away from the harvesting funnel.

[0015] As a further technical solution, the handheld stick is a telescopic handheld stick.

[0016] As a further technical solution, the picking bag and the picking funnel are connected by a clamp.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features several jujube-holding rails on a harvesting funnel and a cutting mechanism surrounding the funnel. The jujubes are first held in place by the rails, and then the cutting mechanism is used to cut off the stems or hanging parts of the jujubes. This design makes harvesting fresh jujubes convenient and easy, solving not only the injury problem caused by inertia when the harvesting funnel is pulled directly in existing technology, but also the problem of some jujubes being unable to be harvested due to the space occupied by the cover placed above the funnel in traditional technology.

[0024] Example 1 Figure 1 An embodiment of the portable jujube-picking device of the present invention is shown, including a picker 1, a picking bag 2 disposed at the bottom of the picker 1, and a hand handle 3 disposed on one side of the picker 1; the picker 1 includes a picking funnel 4 with an open top, a plurality of jujube-holding rails 5 disposed around the circumference of the picking funnel 4, a cutting mechanism 7 sleeved on the outside of the picking funnel 4 and rotatably connected to the picking funnel 4, and a driving mechanism 8 for driving the cutting mechanism 7 to rotate. This invention features several jujube-holding railings 5 ​​on a harvesting funnel 4, and a cutting mechanism 7 is fitted over the harvesting funnel 4. First, the jujubes are held in place by the jujube-holding railings 5 ​​inside the harvesting funnel 4. Then, the rotation of the cutting mechanism 7 cuts off the jujube stems or jujube hanging parts. This design makes harvesting fresh jujubes convenient and easy. It not only solves the problem of injury caused by inertia when the harvesting funnel 4 is pulled directly in the prior art, but also solves the problem of some jujubes being unable to be harvested due to the space occupied by the cover above the harvesting funnel 4 in the traditional technology.

[0025] As one embodiment of the portable jujube-picking device of this utility model, an arc-shaped notch is provided at the end of the picking funnel 4 away from the hand-held rod 3, thereby forming an arc-shaped baffle 9 on the opposite side of the arc-shaped notch; a plurality of jujube-holding rails 5 are evenly distributed at the arc-shaped notch, and gaps 6 are provided between the arc-shaped baffle and the end jujube-holding rails and between adjacent jujube-holding rails 5. The arc-shaped baffle 9 of this utility model can prevent jujubes from splashing when the jujube cake or jujube stem is cut, and prevent them from falling out from the other side of the picking funnel 4.

[0026] As an embodiment of the portable jujube-picking device of this utility model, the top of the jujube-clamping railing 5 is spiked, which facilitates the insertion of the jujube stem or jujube hanging into the gap 6 between adjacent jujube-clamping railings 5.

[0027] As an embodiment of the portable jujube picking device of this utility model, the picking funnel 4 includes an upper open cylinder 27, a lower conical cylinder 28 and a funnel outlet 29 at the bottom.

[0028] As an embodiment of the portable jujube picking device of this utility model, the height of the jujube-holding railing 5 is at least 1 / 2 of the height of the open cylinder 27 of the picking funnel 4; or the height of the jujube-holding railing 5 is greater than or equal to 5cm. The above-mentioned height setting of this utility model makes the gap 6 for accommodating the jujube stem or jujube hanging sufficiently deep, so as to avoid it from coming out of the gap 6 during the cutting process and affecting the cutting.

[0029] As an embodiment of the portable jujube picking device of this utility model, the cutting mechanism 7 includes an annular base 11 sleeved on the outside of the picking funnel 4 via a bearing 10, and a plurality of cutting blades 12 arranged circumferentially on the annular base 11.

[0030] As an embodiment of the portable jujube-picking device of this utility model, the number of cutters 12 is equal to the number of gaps 6, and the cutters 12 are arranged behind the corresponding gaps 6 according to the rotation direction of the cutter mechanism.

[0031] As an embodiment of the portable jujube picking device of this utility model, the cutter 12 is provided with a blade 13, and the blades 13 of several cutters 12 are in the same direction and are all arranged at the front of the cutter 12 along the rotation direction of the cutter 12.

[0032] As an embodiment of the portable jujube-picking device of this utility model, the height of the cutter 12 is equal to the height of the jujube-holding railing 5, and the width of the cutter 12 is less than or equal to the width of the jujube-holding railing 5.

[0033] As an embodiment of the portable jujube picking device of this utility model, the cutter 12 has two states. When not in operation, along the rotation direction of the cutter 12, the cutter 12 is located behind the corresponding gap 6 and corresponds to the position of the jujube-catching railing 5 or the arc-shaped baffle so that it does not occupy the position of the adjacent gap behind it. When in operation, the cutter 12 rotates, and its rotation path covers at least one gap 6 in front.

[0034] As one embodiment of the portable jujube-picking device of this utility model, the driving mechanism 8 includes a first protrusion 14 disposed on the annular base 11, a second protrusion 15 disposed on the hand handle 3, a driving rod 16 slidably disposed on the second protrusion 15, and a transmission rod 17 connecting the driving rod 16 and the first protrusion 14. The two ends of the transmission rod 17 are respectively hinged to the driving rod 16 and the first protrusion 14. When using this utility model, simply pulling the driving rod 16 will cause the driving rod 16 to drive the annular base 11 to rotate through the transmission rod 17, thereby realizing the rotational cutting of the cutter 12.

[0035] As an embodiment of the portable jujube picking device of this utility model, a positioning stop bar 18 for positioning the reset end point of the cutting blade 12 is also provided on the side wall of the picking funnel 4; when the first protrusion 14 abuts against the positioning stop bar 18, the cutting blade 12 is accurately reset (completely leaving the gap 6); the setting of the positioning stop bar 18 of this utility model avoids the cutting blade 12 from occupying the gap 6 due to excessive reset of the annular base 11.

Then, pull the operating handle 21 away from the harvesting funnel 4. The drive rod 16 slides away from the harvesting funnel 4, the spring is compressed, and at the same time, the transmission rod 17 transmits force to the first protrusion 14, thereby driving the annular base 11 to rotate. The annular base 11 drives the cutter 12 to rotate through the gap 6, thereby cutting off the jujube stalk or stem. Then, release the operating handle 21. Under the action of the spring, the drive rod 16 returns to its original position, thereby driving the cutter 12 to return to its original position.
