Description

Technical Field

[0001] This invention pertains to sea buckthorn fruit harvesters, and more particularly to a fully automatic, multi-functional sea buckthorn fruit harvester. Background Technology

[0002] Sea buckthorn, grapes, goji berries, jujubes and other forest and fruit plants are important economic plants in my country and are cultivated on a large scale in many parts of the country. However, harvesting is a major problem. Traditional methods of harvesting sea buckthorn fruits involve picking them by hand or using hand vibrating sticks. The fruits are then collected in baskets or on plastic sheets on the ground and transported manually. This method is labor-intensive, time-consuming and inefficient. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic multi-functional harvester for sea buckthorn fruit. Its structure is reasonable, and it can not only replace manual labor with mechanization, but also complete the harvesting, cleaning, collection and loading of sea buckthorn fruit in one go. There is no waste in the harvesting. Moreover, this harvester is easy to operate, has stable and reliable working performance, and high working efficiency.

[0004] The objective of this invention is achieved as follows: A fully automatic multi-functional harvester for sea buckthorn fruit comprises a self-propelled frame equipped with liftable wheels controlled by lifting cylinders; a conical guide is located at the front end of the self-propelled frame; a casing with front and rear openings is mounted on the self-propelled frame via an upper frame; two annular conveyors with scrapers evenly distributed along both sides of the casing are installed inside the casing; an inverted V-shaped rubber baffle is fixed along the center line of the frame between the two annular conveyors; and two symmetrical rubber curtains are installed on the front and rear openings of the casing. Located inside two annular conveyors, two sets of arc-shaped vibrating frames and two sets of rotary vibrators driven by power are successively installed on both sides of the front of the frame. The rotary vibrator is a eccentric vibrating shaft driven by power, with the tube shaft mounted on the eccentric vibrating shaft through bearings. Vibrating rods are evenly distributed radially on the tube shaft. On the outside of the two annular conveyors, which are higher than the top surface of the machine casing at the rear of the frame, there are collection boxes that are driven by unloading cylinders to unload. The unloading end of the annular conveyor is connected to the inlet of the collection box through a guide chute. Spiral cleaners are installed at the lower rear of the two annular conveyors.

[0005] This invention includes a cab, an engine system, a hydraulic operating system, an electronic control system, a mechanical transmission system, and a control system. Four lifting wheels are mounted on a self-propelled frame, each equipped with a lifting cylinder. Under the action of the cylinders, the four wheels can move up and down synchronously. A conical guide is installed at the front end of the frame. Inside the front end of the frame, there are two sets of annular conveyors with evenly distributed scrapers. Multiple sets of support rollers are fixed to the frame. The annular conveyors run around the support rollers and drive wheels under the drive of a hydraulic motor. Two rubber curtains are also fixed, one side of which is hinged to the frame fixing plate. The eccentric shaft is hinged to the frame via bearings, with a swing arm fixed to its upper end. The shafts of the left and right eccentric turntables fixed to the hydraulic motor and the swing arm with the elongated hole are connected to form a left and right eccentric force. Arc-shaped vibration rods coated with a flexible material layer are evenly distributed and hinged to the eccentric shaft. One end of the connecting arm is hinged to the arc-shaped vibration rod, and the other end is hinged to the shaft fixed to the frame. Vibration rods coated with a flexible material layer are evenly distributed around the two sets of rotary vibrators. The bearings at both ends of the tube shaft are sleeved on the eccentric vibration shaft. The high-speed rotation of the eccentric vibration shaft generates a high-frequency vibration, and it can also rotate on its own axis. The lower end of the eccentric main shaft is sleeved with... It features angled slant plates, with a pressure bearing fixed between the upper and lower slant plates. The upper slant plate, under axial force, rotates in conjunction with the slant plate fixed to the frame, generating a reciprocating thrust. The actuator, under this thrust, produces an up-and-down vibration frequency. Two connecting arms are hinged to bearing seats at both ends of one eccentric main shaft, and to a fixed seat on the frame at the other end. The upper end of the eccentric main shaft is connected to a reducer, which is hinged to a connecting rod. Both ends of the eccentric main shaft are hinged to the reducer. The middle reduction input shaft is hinged to the engine output power via the eccentric main shaft. The front and rear sections are also fixed... It has two rubber curtains, one side of which is hinged to the frame beam; the bottom of the frame is horizontally hinged with a drive shaft and a driven shaft, and a rubber conveyor belt is attached to it to transport the shaken-down sea buckthorn fruits to the circular conveyor. Rubber baffles are evenly hinged to one side of the frame of the conveyor, and the other side is connected to the circular conveyor; the lower rear of the circular conveyor is hinged at an angle to the hydraulic motor shaft, and a spiral shaft is sleeved on it to form a spiral cleaner; the upper front of the frame is fixed with the control cab and engine, and the rear top of the circular conveyor is fixed with a cleaner fan. A V-belt connects the cleaner fan pulley reducer pulley to the pulley, which transmits power. The air inlet is connected to the guide chute of the circular conveyor, and the air outlet blows out the impurities; the guide chute sends the fruits into the collection box. One end of the unloading cylinder is hinged to the collection box, and the other end is hinged to the frame. Under the action of the cylinder, the collection box is lifted, and the sea buckthorn fruits are unloaded into the transport vehicle.

[0006] In actual production, this invention is a self-propelled harvester, including an engine system, hydraulic system, electronic control system, mechanical transmission system, and control system. When the engine starts, four lifting wheels are installed on the self-propelled frame, each wheel equipped with a lifting cylinder. Under the action of the hydraulic system, the four wheels under the cylinders can move up and down synchronously, adjusting the working distance of the whole machine from the ground. A conical guide is set at the front end of the frame to gather branches inside the machine. There are two sets of circular conveyors at the front end of the frame, with scrapers evenly distributed. Multiple sets of support rollers are fixed to the frame. The circular conveyors run around the support rollers and drive wheels under the drive of a hydraulic motor, lifting the sea buckthorn fruit to the collection box. Two rubber curtains are also fixed, one side of which is hinged to the frame fixing plate to prevent shaking and falling. The fruit falls into the machine; the first-stage arc-shaped vibrator has two sets of eccentric rotating shafts hinged to the frame via bearings, with a swing arm fixed at the top. The left and right eccentric rotating disks fixed to the motor are connected to the swing arm with the elongated hole. The motor rotates at high speed, generating left and right eccentric forces. Arc-shaped vibrating rods coated with a flexible material layer are evenly hinged to the eccentric rotating shafts. One end of the connecting arm is hinged to the arc-shaped vibrating rod, and the other end is hinged to the rotating shaft fixed to the frame. The arc-shaped vibrating rods contact the branches, causing the branches to resonate and shake the fruit off; the second-stage rotary vibrator has two sets of rotary vibrators with vibrating rods coated with soft rubber material evenly distributed around them. The bearings at both ends of the tube shaft are connected to the eccentric vibrating shaft. During high-speed eccentric rotation, a high-frequency vibration is generated. It can also rotate on its own. An angled downward-sloping disk is fitted at the lower end of the eccentric vibrating shaft, and the upper... A pressure bearing is fixed between the two lower inclined plates. Under the rotational power of the eccentric vibration shaft, the upper inclined plate and the lower inclined plate fixed on the frame generate a reciprocating thrust. The rotary vibrator generates an up-and-down vibration frequency under the action of the thrust. The two connecting arms are respectively hinged to the bearing fixing seats at both ends of one end of the eccentric main shaft, and the other end is hinged to the fixing seat on the frame. The upper end of the eccentric shaft is sleeved with the reducer, the reducer is hinged to the connecting rod, the two ends of the drive shaft are hinged to the reducer, and the middle reduction input shaft is hinged to the engine output power via the drive shaft. Two rubber curtains are also fixed at the front and rear, one side of which is hinged to the frame fixing plate to prevent fruit from falling into the machine. The bottom of the frame is horizontally hinged with the drive shaft and the driven shaft, and a rubber conveyor belt is attached to them to send the fallen fruit into the circular conveyor. The side frame is evenly fitted with upward-sloping rubber baffles that automatically seal against the main trunk, preventing fruit from falling to the ground through gaps. A transverse conveyor feeds the fallen fruit into a circular conveyor. At the rear of the circular conveyor, a spiral shaft is hinged to a hydraulic motor shaft, forming a spiral cleaner that pushes fallen branches and impurities out of the machine to prevent blockage. The control cab and engine are fixed at the front of the upper part of the frame, and a cleaning fan is fixed at the top of the circular conveyor at the rear. The air inlet is connected to the guide chute of the circular conveyor to suck in impurities, and the air outlet blows them out, cleaning the fruit. The guide chute feeds the fruit into a collection box. One end of the unloading cylinder is hinged to the collection box, and the other end is hinged to the frame. The cylinder lifts the collection box, unloading the sea buckthorn fruit into the transport vehicle.

[0007] This invention employs a self-propelled power system, allowing the machine to straddle the fruit trees in a sea buckthorn forest to harvest the fruit. Four wheels, controlled by hydraulic cylinders, can be raised and lowered synchronously to adjust for optimal working conditions. The first stage uses two sets of arc-shaped vibrators that swing left and right, their curved vibrating rods contacting the branches to generate a resonant force that shakes the fruit off. If any fruit remains, the second stage uses two sets of rotating vibrators to dislodge it. The vibrating rods insert into each branch, generating a resonant force that shakes all remaining fruit off. Two sets of rubber baffles, forming a V-shape, contact the tree roots to guide the fruit into the conveyor, preventing it from falling to the ground. Two sets of rubber curtains at the front and rear contact the fruit trees to prevent fallen fruit from entering the machine, significantly reducing waste. A spiral cleaning machine removes fallen branches to prevent blockage of the conveyor channel, while a cleaning fan removes leaves from the fruit, resulting in clean fruit. The primary conveyor collects the fruit and sends it to the circular conveyor. The circular conveyor then sends the clean fruit into the collection box. Under the action of the unloading cylinder, the collection box pours the fruit into the transport vehicle, automatically completing the collection, feeding, and loading process.

[0008] This invention achieves fully automated mechanized harvesting of sea buckthorn fruit by having the farmer straddle a sea buckthorn tree and vibrate the branches with a high-frequency vibration device. The fruit is then shaken off the branches and fed into a collection box via a conveyor and a cleaning system.

[0009] This invention has a reasonable structure, which can not only replace manual labor with mechanization, but also realize the complete harvesting, cleaning, collection and loading of sea buckthorn fruits in one go; there is no waste in harvesting, and this harvester is easy to operate, has stable and reliable working performance and high work efficiency.
