Description

Technical Field

[0001] The invention relates to a reciprocating chestnut picking device and method, belonging to the technical field of agricultural auxiliary equipment. Background Art

[0002] When chestnuts mature, most of their involucral pods (chestnut pods) crack, allowing the chestnuts to burst from their pods and fall naturally to the ground. The chestnut ripening period often experiences high temperatures and heavy rain. Failure to harvest in a timely manner can significantly impact chestnut quality and farmers' income. Current harvesting methods rely primarily on manual picking, which is labor-intensive, costly, and inefficient. This is particularly true in high-quality chestnut-growing areas, where chestnut trees grow on the undulating slopes of mountains and hills or on terraced fields that wind around the mountains. The complex and diverse environment beneath the trees contributes to the high labor costs of harvesting and is a fundamental obstacle to mechanized harvesting. Chinese patent CN2017216853889 "A fully automatic chestnut picking machine" uses air suction to automatically pick chestnuts, and Chinese patent CN2010205509585 "Chestnut picker" uses semi-mechanized picking of chestnuts. The problems are: 1. Semi-mechanized picking is inefficient or contains a high amount of impurities; 2. Mechanized operations cannot be performed due to the complex environment of the chestnut garden or the small row spacing; 3. The air suction picking equipment is prone to picking up weeds, stones, soil, etc. during the picking process. Summary of the Invention

[0003] The purpose of the present invention is to provide a reciprocating chestnut picking device and method, which can be used to pick chestnuts on the ground under chestnut trees, saving manpower, reducing labor intensity and automatically cleaning. It is easy to use and has a compact structure, solving the above-mentioned technical problems existing in the existing technology.

[0004] The technical solution of the present invention is:

[0005] A reciprocating chestnut picking device comprises a picking roller, a bracket and a handle, the two ends of the bracket are respectively connected to the centers of the two side surfaces of the picking roller and serve as the rotating shaft of the picking roller, and the middle part of the bracket is connected to the handle; the two side surfaces of the picking roller are side end plates, and the two side end plates are connected as a whole by multiple transverse steel bars; multiple T-shaped picking plates are arranged between the two side end plates, and the T-shaped picking plates are made of elastic rubber material and consist of arc segments and connecting ribs. The connecting ribs are perpendicular to the tangent of the arc segments to form a T shape, and the lower end of the connecting ribs is connected to the transverse steel bars. The arc segments of multiple T-shaped picking plates are combined together to form a complete circular ring, and multiple circular rings with the same structure are parallel It is arranged between the two side end plates to form the outer circle of the picking roller; the width of the gap between two adjacent circular rings is slightly smaller than the outer diameter of the chestnut; since the T-shaped picking plate is made of elastic rubber material and has a certain degree of elasticity, the pressure generated between the picking roller and the ground during the rotation (forward or backward) of the handle pushes the picking roller, and the chestnuts on the ground are squeezed into the gap between the two adjacent circular rings. As the pressure between the picking roller and the ground increases, the chestnuts squeezed into the gap between the two adjacent circular rings pass through the gap and fall into the picking roller, completing the chestnut picking; shaking the picking roller during the picking process can clean up stones, soil blocks, weeds, etc. that are mixed in the picking process.

[0006] The arc segment thickness of the T-type picking plate is less than the outer diameter of 1 / 2 Chinese chestnut. If the arc segment thickness is too large, the Chinese chestnut that squeezes into the space between two adjacent rings is difficult to fall into the picking roller.

[0007] The outer diameter of the side end plate is the same as the outer diameter of the picking roller composed of a plurality of T-shaped picking plates, and plays a supporting role in the picking operation.

[0008] The side end plate is provided with a discharge door, which is connected to the side end plate via a spring hinge.

[0009] The discharge door is provided with a discharge door switch.

[0010] The handle is a telescopic handle.

[0011] A reciprocating chestnut picking method adopts the above-mentioned picking device, and pushes the picking roller forward or backward through the handle. The pressure generated between the picking roller and the ground during the rotation squeezes the chestnuts on the ground into the gap between two adjacent rings; as the pressure between the picking roller and the ground increases, the chestnuts squeezed into the gap between the two adjacent rings pass through the gap and fall into the picking roller, completing the chestnut picking; during the picking process, the picking roller is shaken to clean up debris.

[0012] After all the chestnuts are picked, open the unloading door and take out the picked chestnuts.

[0013] The positive effects of the present invention are as follows: when the ground environment under the chestnut trees is relatively complicated, the chestnut orchard is closed, the environment under the trees is complex, or the row spacing is too small, chestnut picking operations can be carried out, which can save labor, reduce labor intensity, and automatically clean the chestnuts. It is easy to use and has a compact structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below through embodiments with reference to the accompanying drawings.

[0021] A reciprocating chestnut picking device comprises a picking roller, a bracket 6 and a handle 7. The two ends of the bracket 6 are respectively connected to the centers of the two side surfaces of the picking roller and serve as the rotating shaft of the picking roller. The middle part of the bracket 6 is connected to the handle 7. The two side surfaces of the picking roller are side end plates 2, and the two side end plates 2 are connected as a whole by multiple transverse steel bars 3. A plurality of T-shaped picking plates 1 are arranged between the two side end plates 2. The T-shaped picking plates 1 are made of elastic rubber material and consist of an arc segment 8 and a connecting rib 10. The connecting rib 10 is perpendicular to the tangent of the arc segment 8 to form a T shape. The lower end of the connecting rib 10 is connected to the transverse steel bar 3. The arc segments of multiple T-shaped picking plates 1 are combined together to form a complete circular ring. Identical circular rings are arranged in parallel between the two side end plates 2 to form the outer circle of the picking roller; the width of the gap 11 between the two adjacent circular rings is slightly smaller than the outer diameter of the chestnuts; since the T-shaped picking plate 1 is made of elastic rubber material and has a certain degree of elasticity, the pressure generated between the picking roller and the ground during the rotation (forward or backward) of the handle pushes the picking roller, and the chestnuts on the ground are squeezed into the gap 11 between the two adjacent circular rings. As the pressure between the picking roller and the ground increases, the chestnuts squeezed into the gap 11 between the two adjacent circular rings pass through the gap and fall into the picking roller, completing the chestnut picking; shaking the picking roller during the picking process can clean up stones, soil blocks, weeds, etc. that are mixed in the picking process.

[0022] The arc section 8 thickness of described T-type picking plate 1 is less than the outer diameter of 1 / 2 Chinese chestnut.If arc section 8 thickness is too large, the Chinese chestnut that squeezes into the space 11 between adjacent two circular rings is difficult to fall in the picking roller.

[0023] The outer diameter of the side end plate is the same as the outer diameter of the picking roller composed of a plurality of T-shaped picking plates, and plays a supporting role in the picking operation.

[0024] The side end plate 2 is provided with a discharge door 5 , which is connected to the side end plate 2 via a spring hinge 4 .

[0025] The discharge door 5 is provided with a discharge door switch 9 .

[0026] The handle 7 is a telescopic handle.

[0027] A reciprocating chestnut picking method adopts the above-mentioned picking device, and pushes the picking roller forward or backward through the handle. The pressure generated between the picking roller and the ground during the rotation squeezes the chestnuts on the ground into the gap 11 between two adjacent rings; as the pressure between the picking roller and the ground increases, the chestnuts squeezed into the gap 11 between the two adjacent rings pass through the gap and fall into the picking roller, completing the chestnut picking; during the picking process, the picking roller is shaken to clean up debris.

[0028] After finishing picking up all chestnuts, open the discharge door 5 and take out the picked chestnuts.

[0029] In an embodiment, the handle is a retractable metal handle with a length of 1-2 meters, which is used to facilitate the space under the tree and can be appropriately adjusted to suit different heights of people. The discharge door is self-locking at the discharge port via a spring hinge to prevent chestnuts from being scattered on the ground during the picking operation.

[0030] In this embodiment, the two side end plates are connected by 14 transverse steel bars, and a number of T-shaped pick-up plates are set on the transverse steel bars. The transverse steel bars are 50mm long ordinary steel bars, which serve as the skeleton of the pick-up roller. The length of the transverse steel bars is selected to consider the picking flexibility during the picking process.

[0031] The T-shaped picking plate is made of rubber. The chestnuts are picked up by the squeezing force of the picking roller. The chestnuts fall into the inside of the picking roller under the action of gravity as the picking roller moves.

[0032] The length of the telescopic metal handle is adjusted according to the work site environment to achieve the best working posture and the best working method for workers - saving effort and achieving picking efficiency; first, during the operation, the picking roller is manually pushed and pulled to pick up the freely falling chestnuts, and then after completing a pushing and pulling operation, the picking roller is shaken left and right to clean and remove impurities (remove stones, soil blocks and weeds mixed in the picking equipment during the picking process), and finally the unloading door is opened to unload the picked chestnuts to the designated location, completing a picking operation.

[0033] The most important innovations of the invention are: 1. T-shaped picking plate; the width of the gap between the circular rings is slightly smaller than the outer diameter of the chestnut. During the picking process, the chestnuts are picked up by squeezing force and collected by gravity; 2. Self-cleaning; after completing the picking operation, shake it left and right to clean and remove impurities; 3. The telescopic metal handle is used to facilitate appropriate adjustment according to the space under the tree and the height of people.
