Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fruit harvesting equipment, and specifically relates to a floor fruit picking device. BACKGROUND

[0002] The fruit industry is the third largest industry in China after grain and vegetables, and the total area of various types of fruit cultivation and planting has been the largest in the world. Fruits generally have the highest nutritional value when they naturally fall off after ripening. In order to facilitate harvesting and maintain their nutritional value, mechanical vibration or manual knocking is generally used to make the ripe fruits on the tree fall off, and then a floor fruit picking device is used to pick up and separate the impurities. The planting environment of red jujube, walnut, chestnut, Chinese red pine, pistachio, apricot, olive, tea fruit or coffee meets the conditions for agricultural machinery operation, so this method can be used for harvesting.

[0003] Chinese Patent No. ZL202322504177.2 discloses a green walnut collecting device, which includes a frame, a collecting plate vertically arranged on the frame, a plurality of rollers rotatably arranged on one side of the collecting plate, a feeding motor drivingly connected to the rollers, the rollers being arranged parallel to the width direction of the collecting plate, the plurality of rollers being arranged in sequence along the length direction of the collecting plate, a gap being arranged between the rollers and the collecting plate, a collecting box being arranged on the side of the collecting plate away from the rollers, the top of the collecting box being open, a collecting cover being arranged between the top of the collecting plate and the opening of the collecting box, an inlet being arranged at one end of the collecting cover, an outlet being arranged at the other end of the collecting cover, the inlet being connected to the top of the collecting plate, the outlet being arranged corresponding to the opening of the collecting box, the collecting cover being arranged downwardly inclined towards the collecting box. This device replaces manual walnut collecting work, reduces labor intensity and labor cost, and improves collecting efficiency. However, this device is only suitable for the inter-row road of trees with the same width as the rollers, and the road with a width greater than the rollers will cause the fallen fruits on both sides of the road to be unable to be collected, which requires back-and-forth collection. Secondly, when encountering complex inter-row roads, the protruding road surface is easy to cause damage to the stirring rods on the rollers, and the fruits falling on the concave ground cannot be in contact with the rollers, so they cannot be collected, thus the use effect is limited.

[0004] Chinese Patent No. ZL201520004784.5 discloses a fruit picking mechanism and a red jujube harvester with the mechanism, which comprises a fruit sweeping unit, a fruit shoveling unit, a fruit raking unit and a belt conveying mechanism. The fruit sweeping unit is arranged in front of the fruit shoveling unit and is used to sweep the scattered fruits on the ground into the fruit shoveling unit. The fruit raking unit and the belt conveying mechanism are arranged above and behind the fruit shoveling unit respectively. The fruit raking unit is used to rake the fruits on the fruit shoveling unit to the belt conveying mechanism. The fruits that have fallen on the ground before harvesting can be picked up together with the fruits on the harvesting machine on the harvesting tree. The technical solution comprises two parallel sweeping discs to form the fruit sweeping unit, which can sweep the scattered fruits on the ground into the fruit shoveling unit without being limited by the flatness of the ground. However, the range of collecting scattered fruits still cannot be adjusted, and the collection needs to be back and forth. Secondly, the sweeping disc is always in contact with the ground, and the problem of accelerated wear of the sweeping disc exists in non-working form and when encountering ground undulations.

[0005] Chinese Patent No. ZL202220617404.5 discloses a red jujube picking device, which comprises a driving vehicle, a rack, a cleaning mechanism, a conveyor belt, a feeding driving mechanism, a screening roller way and a material collecting tank arranged on the rack. The discharge end of the conveyor belt is arranged directly above the feeding end of the screening roller way, and the discharge end of the screening roller way extends to the slot opening of the material collecting tank. A plurality of shovel plates are arranged on the conveyor belt and on the outer side of the conveyor belt. During the forward movement of the driving vehicle, the red jujubes on the ground are swept to the conveyor belt with the shovel plates by the cleaning device, and the conveyor belt is driven by the feeding driving mechanism to move the feeding to the screening roller way. The leaves and dust in the red jujubes are screened out by the screening roller way, and the screened red jujubes are sent to the material collecting tank. The device has low energy consumption, can ensure the quality of red jujube picking, and can remove leaves and dust. However, the effect of removing impurities such as leaves, branches or soil clumps by vibration is very limited. Red jujubes and impurities need to be slowly and in small batches conveyed to the cleaning screen. If the speed is too fast or the conveying amount is too large, the impurities will roll into the material collecting tank with the red jujubes before being screened out, so the impurity removal effect is very limited.

Specifically, the multi-way reversing valve 111 controls the extension and retraction of the first hydraulic rod 214 close to the side of the road surface unevenness. If the road surface unevenness is wide or when the device is not in operation, the two first hydraulic rods 214 are controlled to extend and retract simultaneously. When the first hydraulic rod 214 retracts, the tension beam 213 is pulled, the angle between the tension beam 213 and the mounting plate 11 is reduced, the lifting frame 211 is translated upward under the action of the tension beam 213 and the connecting rod 212, and the converging part 22 is lifted upward to avoid the protruding road surface or to avoid the cleaning brush 2251 in the converging part 22 from contacting the ground when the device is not in operation, thereby preventing the converging part 22 from colliding with the protruding road surface and preventing the cleaning brush 2251 from rubbing unnecessarily and causing resistance to the driving mechanism 1 when the device is not in operation.

Specifically, the multi-way reversing valve 111 controls the extension and retraction of the second hydraulic rod 221 close to the side or both sides. If the road width decreases, the second hydraulic rod 221 is controlled to extend, the second hydraulic rod 221 pushes the converging part 22 to rotate around the lifting frame 211, the front end of the converging part 22 approaches the converging part 22 on the other side, or the two converging parts 22 rotate to approach each other, thereby preventing the front end of the converging part 22 from colliding with the tree trunk.

[0092] If a road section with gradually increasing road width is encountered, the second hydraulic rod 221 is controlled to retract through the multi-way reversing valve 111, the second hydraulic rod 221 pulls the converging part 22 to rotate the converging part 22 around the lifting frame 211, the front end of the converging part 22 approaches the road edge, or the two converging parts 22 rotate away from each other, so that the fallen fruits on the road are collected into the two converging parts 22.
