A hand-held brush-type lycium fruit picking device

Abstract

This invention relates to a harvesting device, specifically a handheld vibrating brush-type goji berry harvesting device, belonging to the field of agricultural machinery technology. The invention discloses a handheld vibrating brush-type goji berry harvesting device, which mainly includes a handle, a vibration mechanism, a brushing mechanism, and a collection mechanism. This harvesting device uses two stepper motors for power, which, through a clever gear transmission method, drive the vibration mechanism and the brushing mechanism to rotate, jointly completing the vibration and brushing operation on the goji berry branches. After the mature goji berries are dislodged by the vibration and brushing force, they fall into the collection mechanism under their own gravity. This harvesting device integrates harvesting and collection, avoiding the problem of mature goji berries falling to the ground after being harvested by vibrating brushing and requiring secondary manual collection, thus effectively improving the efficiency of goji berry harvesting.

Description

Technical Field

[0001] This invention relates to a harvesting device, and more particularly to a handheld vibrating brush type goji berry harvesting device, belonging to the field of agricultural machinery technology. Background Technology

[0002] Goji berries belong to the genus *Lycium* in the family Solanaceae, and are perennial deciduous shrubs. Goji berries are inflorescence-less plants, producing small berries, and flowering and fruiting occur simultaneously. The plant has slender, thorny branches, and the fruits ripen quickly, are small in size, and have soft, elastic flesh, but are easily damaged. According to relevant statistics, the economic value of damaged goji berries can drop significantly, sometimes by as much as 90%, which is one of the main factors restricting mechanized harvesting.

[0003] Currently, goji berry harvesting in my country is mostly done manually, which is inefficient and costly. If not harvested in time, the goji berries will quickly spoil, causing significant economic losses. Furthermore, due to rising labor costs in recent years, the hot weather and high labor intensity during peak harvest season often make it difficult to harvest in time, missing the prime harvest period. Given these circumstances, achieving mechanized and intelligent goji berry harvesting is of great significance for increasing growers' income and developing the local economy.

[0004] This invention takes into account the actual working environment and operational requirements of goji berries and designs a handheld vibrating brush goji berry picking device to complete the goji berry picking work. Summary of the Invention

[0005] The purpose of this invention is to provide a handheld vibrating brush-type goji berry harvesting device. The technical problem to be solved by this invention is: how to use the designed vibrating brush-type goji berry harvesting device to complete the high-efficiency and low-damage harvesting of mature goji berries by coordinating the two actions of vibration and brushing.

[0006] To achieve the above objectives, the technical solution adopted in this invention is a handheld vibrating brush goji berry picking device, the main components of which include: handle 1, optical axis fixing mechanism 2, vibration mechanism 3, combing mechanism 4, and collection mechanism 5.

[0007] The feature is that the handle 1 is fixed to the optical axis fixing mechanism 2, the vibration mechanism 3, the combing mechanism 4, and the collecting mechanism 5 by bolts. The optical axis fixing mechanism 2 is symmetrically distributed on both sides of the optical axis 2-1, and the inserted optical axis 2-1 is fixed by bolts. The entire optical axis fixing mechanism 2 is fixed to the handle 1 by bolts. The function of the vibration mechanism 3 is mainly realized by the crank-slider mechanism, which mainly includes a stepper motor 3-1, a small spur gear 3-2, a large spur gear 3-3, a large bevel gear 3-4, a small bevel gear fixing bracket 3-5, a small bevel gear 3-6, a crank 3-7, a connecting rod 3-8, a slider 3-9, an end cap 3-10, a linear bearing 3-11, a linear bearing support 3-12, and an optical axis guide rail 3-13. The combing mechanism 4 mainly uses a stepper motor to drive a large spur gear to perform circular motion around the main shaft to complete the combing. It mainly includes comb teeth 4-1, stepper motor 4-2, end cap 4-3, large spur gear 4-4, main shaft 4-5, small spur gear 4-6, sealing cap 4-7, and main shaft support 4-8. The collecting mechanism 5 is mainly used to store and transport the harvested goji berries, and includes two parts: a fruit storage hopper 5-1 and a conveying pipe 5-2.

[0008] In the entire vibration process, the stepper motor 3-1 is connected to the small spur gear 3-2 and the large spur gear 3-3 by gears. The crank 3-7 and the small bevel gear 3-6 are fixed together. The axis of the small bevel gear 3-6 is perpendicular to the large bevel gear 3-4. The large bevel gear 3-4 transmits power to the small bevel gear 3-6. The small bevel gear 3-6 drives the crank 3-7, the connecting rod 3-8 and the slider 3-9 to perform reciprocating linear motion on the optical axis 2-1 under the limit of the linear bearing. The small bevel gear 3-6 is fixed on the small bevel gear fixing bracket 3-5. There are a total of 8 optical axis guide rails 3-13, all of which are fixed on the end cover 3-10. The linear bearings 3-11 and linear bearing supports 3-12 are both installed on the optical axis guide rails 3-13. There are 32 linear bearings 3-11 and 8 linear bearing supports. The vibration frequency of the entire vibration mechanism is determined by the speed of the stepper motor 3-1. The harvesting effect is determined by the speed and torque of the motor.

[0009] The power transmission process of the combing mechanism 4 in the entire combing process is as follows: the stepper motor 4-2 transmits power to the small spur gear 4-6, the small spur gear 4-6 transmits power to the large spur gear 4-4, and the rotation of the large spur gear 4-4 drives the main shaft 4-5, which in turn drives the comb teeth 4-1 to rotate, thus realizing the combing function of mature goji berries. The large spur gear 4-4 is fixed to the end cover 4-3, and the main shaft 4-5 is fixed by the main shaft bracket 4-8. Finally, the entire machine is sealed with a sealing cover 4-7 to prevent goji berries and branches from falling into the mechanism and affecting its normal operation. When mature goji berries are picked, they fall into the fruit storage hopper 5-1 under the influence of gravity. The goji berries are then transported to a designated location through the conveying pipe 5-2, effectively avoiding the problem of goji berries falling to the ground after being picked by the vibrating brush and requiring secondary manual collection.

[0010] The beneficial effects of the handheld vibrating brush goji berry picking device of the present invention are: when the present invention is used in goji berry picking operations, it can effectively avoid the problem that not all mature goji berries can be picked due to the use of vibration or brushing methods alone, resulting in mature goji berries being left on the branches. This invention can effectively save labor and improve work efficiency. Attached Figure Description

[0019] The working principle of the vibration mechanism of a handheld vibrating brush goji berry picking device is as follows: After the stepper motor 3-1 is powered on and rotates, it drives the small spur gear 3-2 to rotate.

The large bevel gear 3-4 transmits power to the crank 3-7, which is fixedly connected to the small bevel gear, through a spatial meshing angle of 90° with the small bevel gear 3-6. The crank 3-7 drives the connecting rod 3-8, and the connecting rod 3-8 drives the comb teeth 4-1 to perform reciprocating linear motion on the optical axis guide rail 3-13, thus realizing the vibration picking of goji berries by the vibration mechanism.

[0020] The working principle of the combing mechanism of a handheld vibrating brush goji berry picking device is as follows: the stepper motor 4-2 transmits power to the small spur gear 4-6, the small spur gear 4-6 transmits power to the large spur gear 4-4, and the large spur gear 4-4 transmits power to the entire picking head to drive the entire picking device to rotate and comb, thereby realizing the combing function of goji berries.

[0021] After the vibration mechanism 3 and the combing mechanism 4 of a handheld vibrating brush goji berry picking device work together to pick the goji berries, the goji berries fall into the collection mechanism 5 under the action of gravity, and finally the picking and collection of mature goji berries is completed.
