The pineapple continues to move backward and falls on the drainage plate and then into the collection box through the drainage plate. The picking function of the pineapple is realized through the sprocket and the cutting knife, which has the advantages of good picking effect, high picking efficiency, and simple and reliable structure.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and particularly relates to a pineapple picking device. Background Art

[0002] Pineapples are widely planted in our country and can often be seen in some coastal areas. If pineapples are to be harvested, the time is very short, only less than one month. However, at present, the picking operation of pineapples mainly relies on manual labor, and the manpower required for the entire harvesting operation in the short term accounts for a large part of the production cost. Farmers are eager to reduce the labor burden through some mechanized means. Therefore, it is very necessary for pineapple picking to develop towards mechanization, automation, and humanization. Corresponding to the reduction of the labor force, it is of great significance to improve the quality of the picking operation, productivity, pineapple harvesting efficiency, and reduce the picking intensity, which is the future development trend. Therefore, it is necessary to invent a pineapple picking device. Summary of the Invention

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a pineapple picking device, which has the advantages of good picking effect, high picking efficiency, and simple and reliable structure.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is:

[0005] A pineapple picking device includes a vehicle body bottom plate. Wheels are installed at the rear end of the vehicle body bottom plate, and a universal wheel is provided at the front end of the vehicle body bottom plate;

[0006] A gasoline engine is installed on the vehicle body bottom plate. A collection box is installed in the middle of the vehicle body bottom plate. A belt pulley transmission shaft is installed at the front end of the vehicle body bottom plate through a gear fixing frame. A large belt pulley is installed on the belt pulley transmission shaft. A small belt pulley is installed on the output shaft of the gasoline engine. The large belt pulley and the small belt pulley are connected by a V-belt; Two downwardly inclined guide plates are installed at the front end of the vehicle body bottom plate through a triangular support frame. A gap for the branches to pass through is reserved between the two guide plates. A diversion plate is provided between the guide plates and the collection box;

[0007] Shaft three and shaft one respectively vertically pass through the two guide plates and are fixed to the two guide plates through bearing seats. A gear two and a gear one are rigidly connected to shaft three and shaft one respectively. A large bevel gear is also installed at the lower part of shaft one. The gear two, the gear one, and the large bevel gear are all located below the guide plates. A bevel gear is installed in the middle of the belt pulley transmission shaft. The bevel gear meshes with the large bevel gear, and the gear one meshes with the gear two;

[0008] Above the two guide plates, sprockets are installed in the middle of the first shaft and the third shaft. A double sprocket is installed in the middle of the guide plates through the second shaft. A front cutting blade is also installed on the second shaft. Front sprockets are installed at the front sections of the two guide plates. A stem-pushing chain is installed on the front sprockets and the double sprocket. Pushing plates are provided on the stem-pushing chain. A transport chain is installed between the sprocket and the double sprocket.

[0009] Further, a rear axle is fixed to the rear end of the vehicle body floor through a bearing seat. A wheel is connected to the rear axle through a flange. A small sprocket is also installed on the rear axle. A large sprocket is installed at the other end of the belt pulley drive shaft. The large sprocket and the small sprocket are connected by a chain.

[0010] Further, upper fixing plates are installed on both guide plates through support rods. Both the third shaft and the first shaft vertically pass through the upper fixing plates and are fixed to the upper fixing plates through bearing seats. Upper sprockets are installed on the upper parts of the first shaft and the third shaft on both upper fixing plates. A driven sprocket is provided on the other side of the upper fixing plate. An upper chain is installed on the upper sprocket and the driven sprocket.

[0011] Further, a rear cutting blade is installed on the first shaft. The rear cutting blade is located above the sprocket.

[0012] Further, an auxiliary sprocket is installed on the guide plate. The auxiliary sprocket cooperates with the stem-pushing chain.

[0013] Further, the front gap between the two guide plates is in a flared shape.

[0014] Further, the two guide plates and the parts installed on the two guide plates are symmetrically distributed along the center of the device.

[0015] Further, a small belt pulley is installed on the output shaft of the gasoline engine through a key.

[0016] Further, the universal wheel is fixed to the vehicle body floor through a support seat, and a bearing is provided at the mating part.

[0017] The beneficial effects of the present invention:

[0018] Through the combined action of the belt drive and chain drive of the gasoline engine, the shaft is driven to rotate under the action of the bevel gear set and the meshing of the two gears. The rotation of the shaft drives the sprockets, upper sprockets and rear cutting blade on the shaft to rotate. At the same time, under the action of the chain drive, the stem-pushing chain and the transport chain at the front end of the guide plate both rotate. The pushing plates on the stem-pushing chain gather the leaves of the pineapple, and the front cutting blade cuts the pineapple off from the plant. When the pineapple moves to the rear cutting blade, the rear cutting blade will cut off the redundant fruit stalk. The pineapple continues to move backward and falls on the drainage plate and then into the collection box through the drainage plate. The picking function of the pineapple is realized through the sprocket and the cutting knife, which has the advantages of good picking effect, high picking efficiency and simple and reliable structure.

[0019] The rear axle is equipped with a small sprocket, and the large sprocket installed at the other end of the belt pulley drive shaft is connected to the small sprocket through a chain. The rear axle is rotated by a gasoline engine, thereby enabling the gasoline engine to drive the vehicle forward and reducing the labor intensity of workers.

[0020] Upper fixing plates are installed on both guiding plates through support rods, and upper chains are installed on the upper parts of two shafts located on the two upper fixing plates, realizing synchronous conveying on both sides, improving the conveying efficiency, and preventing the cut pineapples from falling.

[0021] Both guiding plates and the parts installed on the two guiding plates are symmetrically distributed along the center of the device. The front end gap between the two guiding plates converges in a trumpet shape, facilitating the gathering of trees and their entry into the gap between the two guiding plates, and achieving higher harvesting efficiency.

[0038] The working principle of the present invention:

[0039] When picking pineapples, align the middle of the front end of the pineapple picking device with the pineapple planting row. Start the gasoline engine 14. Under the combined action of belt drive and chain drive, the gasoline engine 14 makes the rear wheels 17 rotate. With the cooperation of the rear wheels 17 and the front universal wheels 30 at the front end, the whole device moves forward. While moving forward, under the action of the bevel gear set and the meshing of two gears, the shaft rotates. The rotation of the shaft drives the sprockets 46, upper sprockets 4 and rear cutting blades 48 on the shaft to rotate. Under the action of chain drive, the stem-pulling chain 2, transport chain 9 and upper chain 4 at the front end of the guide plate all rotate.

[0040] When the pineapple enters the picking area, first, the stem-pulling plate on the stem-pulling chain 2 gathers the leaves of the pineapple. The device continues to move forward. When the pineapple reaches the front cutting blade 3, the front cutting blade 3 cuts the pineapple off the plant. At this time, the pineapple continues to move backward under the combined action of the transport chain 9 and the upper chain 4. When the pineapple moves to the rear cutting blade 48, the rear cutting blade 48 cuts off the redundant fruit stalk. The pineapple continues to move backward and falls on the drainage plate 11, and then falls into the collection box 5 through the drainage plate 11, thus completing the pineapple picking process.

[0041] The present invention has been described in detail with reference to the above embodiments. Those of ordinary skill in the art should understand that: modifications or equivalent substitutions can still be made to the specific embodiments of the present invention, and any modification or equivalent substitution that does not depart from the spirit and scope of the present invention shall be covered by the scope of these claims.
