Abstract
Description
Technical Field
[0001] This disclosure belongs to the field of agricultural auxiliary collection device technology, specifically relating to a chestnut collection device. Background Technology
[0002] The statements herein provide only background information in relation to this disclosure and do not necessarily constitute prior art.
[0003] Chestnuts are a popular nut enjoyed by most people. In the traditional harvesting process, workers knock chestnuts from the trees by hand. The naturally fallen chestnuts roll randomly across the trunk and eventually scatter on the ground. To collect these scattered chestnuts, workers typically use canvas to cover the area around the tree trunk. However, this traditional canvas collection method has limitations; the canvas cannot tightly wrap around the trunk, resulting in inefficient collection. Therefore, workers have tried installing canvas on adjustable ring frames to improve contact between the canvas and the trunk. However, these adjustable ring frames often cannot flexibly adapt to trunks of varying diameters. This results in excessive gaps between the ring frame and the trunk, preventing the canvas from adhering tightly to the surface and affecting both the efficiency and quality of chestnut collection. Utility Model Content
[0004] The purpose of this disclosure is to provide a chestnut collecting device that can at least solve one of the above-mentioned technical problems.
[0005] To achieve the above objectives, one or more embodiments of this disclosure provide a chestnut collecting device, including a first fixing ring and a second fixing ring. The first fixing ring and the second fixing ring are hinged together by a pin to form an openable and closable annular structure. The first fixing ring is provided with a fixing buckle, and the second fixing ring is provided with an adjusting buckle. Both the first fixing ring and the second fixing ring are provided with multiple sets of oblique mounting screw holes, which are connected to the screw rod supporting the canvas.
[0006] Furthermore, a connecting plate for mounting the pin is provided at the hinge joint of the first and second fixed rings.
[0007] Furthermore, the connecting plate is also provided with a rectangular cross-section folding frame, and the folding frame is provided with clips for clamping the woven bag.
[0008] Furthermore, the long side of the folding frame is provided with a hinge point that is consistent with the opening and closing direction of the first and second fixing rings.
[0009] Furthermore, the fixing buckle is fixedly provided with an adjusting band that cooperates with the adjusting buckle.
[0010] Furthermore, the surface of the adjustment belt is provided with a ratchet structure, and the adjustment buckle is provided with a pawl that engages with the ratchet and a torsion spring that resets the pawl.
[0011] Furthermore, the screw is obliquely upward on the side of the first and second fixing rings, forming an acute angle with the horizontal plane.
[0012] Furthermore, the canvas covers the screw in a conical collecting surface.
[0013] Furthermore, the edge of the canvas is provided with straps that connect to the screw.
[0014] Furthermore, the conical collecting surface has an opening at the hinge of the first and second fixing rings.
[0015] The beneficial effects of one or more of the above technical solutions are as follows:
[0016] This disclosure utilizes a hinged, openable annular structure consisting of a first fixed ring and a second fixedly fitted adjusting belt with a ratchet structure and an adjusting buckle with a pawl that engages with the ratchet. This allows the collecting device to adapt to tree trunks of different diameters. Simultaneously, a tapered collecting surface covered by a canvas on the screw forms a funnel-shaped chute that slopes outward and downward from the tree trunk surface. Chestnuts falling on the trunk or branches naturally roll onto the canvas surface and then gather along this slope, thus effectively collecting them. Attached Figure Description
[0017] The accompanying drawings, which form part of this application, are used to provide a further understanding of this application. The illustrative embodiments of this application and their descriptions are used to explain this application and do not constitute a limitation thereof.

[0020] Figure 3 As described in this embodiment of the disclosure Figure 1 Enlarged view of point A;

[0023] like Figures 1 to 3As shown, this embodiment provides a chestnut collecting device, including a first fixing ring 2, a second fixing ring 3, and an adjusting belt 5.
[0024] like Figure 1 As shown, the first fixing ring 2 and the second fixing ring 3 are hinged together by a pin to form an openable and closable ring structure. The openable and closable ring structure allows the collecting device to be easily fitted onto the trunk or the base of a thicker branch.
[0025] A connecting plate 7 for mounting pins is provided at the hinge joint of the first fixing ring 2 and the second fixing ring 3; multiple sets of oblique mounting screw holes are provided on the first fixing ring 2 and the second fixing ring 3, and the mounting screw holes are connected to the screw rod 8 supporting the canvas; the screw rod 8 is obliquely upward on the side of the first fixing ring 2 and the second fixing ring 3, and is set at an acute angle to the horizontal plane.
[0026] Specifically, such as Figure 2 As shown, the canvas covers the screw 8 and is set in a conical collecting surface; through the screw 8 installed obliquely upward and the conical collecting surface covering it, a funnel-shaped slide is formed from the surface of the trunk outward and downward. Chestnuts falling on the trunk or branches naturally roll onto the canvas surface and then gather along the slope.
[0027] The conical collecting surface has an opening at the hinge of the first fixing ring 2 and the second fixing ring 3. The design of the opening structure allows the collecting device to flexibly adapt to the irregular shape of the tree trunk or branches when it is fitted onto the tree trunk or branches, ensuring that the canvas can completely cover the area around the tree trunk or branches and reducing the gaps between the first fixing ring 2 and the second fixing ring 3 and the tree trunk. The edge of the canvas is provided with a strap that connects to the screw 8. The strap device enhances the stability between the canvas and the screw 8, ensuring the collection effect.
[0028] like Figure 3 As shown, a fixing buckle 4 is provided on the first fixing ring 2, and an adjusting buckle 6 is provided on the second fixing ring 3; an adjusting band 5 that cooperates with the adjusting buckle 6 is fixedly provided on the fixing buckle 4.
[0029] Specifically, the surface of the adjusting band 5 is provided with a ratchet structure, and the adjusting buckle 6 is provided with a pawl that engages with the ratchet and a torsion spring that resets the pawl. By pressing the adjusting buckle 6, the pawl can be released from the ratchet. After tightening the adjusting band 5, the adjusting buckle 6 is released, and the pawl automatically engages with the ratchet of the adjusting band 5 under the action of the torsion spring, achieving reliable one-way locking. Furthermore, through the cooperation of the adjusting band 5 and the adjusting buckle 6, the user can easily adjust the spacing between the fixing rings according to the diameter of the tree trunk, thereby adapting to the irregular shape of the tree. In addition, the ratchet structure and the pawl can prevent the adjusting band 5 from accidentally loosening during the adjustment process.
[0030] like Figure 1 and Figure 3As shown, the connecting plate 7 is also provided with a rectangular cross-section folding frame 9. The long side of the folding frame 9 is provided with a hinge point that is consistent with the opening and closing direction of the first fixing ring 2 and the second fixing ring 3. At the same time, the folding frame 9 is provided with a clip 1 for clamping the woven bag. The clip 1 can firmly grasp the opening of the woven bag, ensuring that the woven bag will not easily loosen or fall off during use.
[0031] The working principle of this utility model:
[0032] Workers unfold the hinged first fixing ring 2 and second fixing ring 3 and slip them onto the tree trunk. They then pull the adjusting strap 5 to reduce the ring diameter. At this point, the pawl inside the adjusting buckle 6 automatically engages under the action of the torsion spring. Through the ratchet teeth of the adjusting strap 5, the two rings tightly hug the tree trunk, adapting to the trunk's diameter and forming a rigid support base. Next, multiple screws 8 are inserted into the slanted mounting holes on the side of the fixing rings. The canvas is secured to the screws 8 and the folding frame with straps. Clips fixed around the folding frame hold the woven bag in place. Because the screws 8 extend radially upwards, the canvas naturally forms a tapered dynamic slide that slopes outwards and downwards from the tree trunk surface. Chestnuts falling on the trunk or branches naturally roll onto the canvas surface and then gather along this slope, converging at the folding frame. The chestnuts then flow directly into the woven bag through the folding frame, effectively collecting the chestnuts.
[0033] While the specific embodiments of this disclosure have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this disclosure. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this disclosure are still within the scope of protection of this disclosure.
