Description

A Jujube Picking Machine Based on Synchronous Distance Adjustment Mechanism

technical field

The invention relates to the field of agricultural machinery, in particular to a jujube picking machine based on a synchronous distance adjustment mechanism.

Background technique

In the existing field of agricultural machinery, there have been many inventions for picking and collecting jujubes, most of which are based on people holding jujube sticks, mainly manual harvesting, but this kind of labor intensity is high and the harvesting efficiency is high. Low cost, high cost, great damage to jujube trees, and obvious disadvantages; there are also a few parts that are composed of complex mechanical settings such as air blowing picking devices, picking and conveying devices, fans, vibration excitation devices, and conveying devices, but they are bulky , the structure is complex, the transmission efficiency is low, and it is impossible to harvest the ground red dates. The incomplete collection of dates requires manual secondary picking. This kind of red date harvester has a large turning radius and requires a large turn-around space during harvesting operations. When working in the jujube orchard, the space for turning around in the jujube orchard is limited, which makes it difficult for the harvester to turn around and affects the harvesting efficiency. Or crush jujube trees, causing losses and increasing harvest costs. Moreover, the current jujube harvester has a poor effect on gathering jujube trees before they enter the picking device, which in turn affects the harvesting effect. Therefore, there is an urgent need for mechanical equipment with small size, high efficiency in beating and harvesting jujubes, labor saving, and less damage to jujube trees.

After retrieval, there is a fully hydraulic self-propelled jujube picking and harvesting machine (patent number: 2017203434849), which is mainly composed of an air blowing picking device, a picking and conveying device, a fan, a vibration exciting device, and a conveying device. One, vertically hinged on both sides of the middle of the frame, two rows of conveying devices are installed horizontally directly below the excitation devices on both sides. The shaped wheel is in contact with the ground, the rear end of the conveying device leads to the jujube collecting box, and the jujube collecting box is fixed at the rear end of the frame. It is at the front end of the frame and is located obliquely above the pick-up and conveying device. Its inner side is hinged with the frame, and its outer side is connected with the fan outlet pipe. The upper part of the rear end of the frame, the driver's cab is fixedly connected to the upper part of the front end of the frame, and the frame is installed on the traveling wheel system. At the same time, the vibrating device shakes off the jujubes on the tree and rolls them to the conveying device along the inclined brush. The conveying device transports the jujubes to the jujube box, and completes the harvesting of jujubes on the trees and jujubes on the ground. Compared with the existing self-propelled jujube harvester, this device has the advantages of hydraulic drive, high transmission efficiency, simple structure, and an air-blown pick-up device at the front that can pick up fallen jujubes, but its jujube vibrating mechanism vibrates The direction is single, and it is impossible to achieve all-round jujube beating so as to ensure that no dates are leaked during the beating process. The efficiency of beating dates is low, and the beating device is fixed below the machine, and only jujube trees within the specified height can be hit. For jujube trees in different regions Due to the lack of agronomic technology and the difference in the growth status of the crops, the straightness error of the trunk of the jujube tree is relatively large. The distance between the symmetrical jujube beating vibration devices of this device is fixed, which cannot ensure that the machine will pass through the trunk smoothly during the process of moving without correcting the jujube tree. Trees do damage. Therefore, it is not suitable for picking and collecting large-scale jujubes.

After searching, there is a self-propelled jujube harvester (patent number: 2016108830391), including: frame, picking system, conveying system, self-propelled chassis, drive system and control system; the middle part of the frame is an inverted "U" shape The channel is used to pass jujube trees; the front end of the frame is provided with a branch supporter; the picking system is arranged on the frame; the conveying system is used to transport and collect red dates; the self-propelled chassis is set on the frame; the self-propelled chassis includes : Walking system and time-sharing four-wheel steering system; the drive system is set on the frame for driving the picking system, conveying system and self-propelled chassis; the control system is set on the frame for controlling the drive system, picking system, Conveyor system and self-propelled chassis. The main working steps of the device are that the picking system shakes off the red dates through vibration, the fruit collecting conveying device receives and transports the red dates shaken off by the picking system, guides the red dates to the first chain conveying device, and then passes through the second chain conveying device, The jujube is transported to the fruit collection box, or the jujube is transported to the outside car box. Although compared with the fully hydraulic self-propelled jujube picking and harvesting machine, the device is equipped with a torsion spring reset unit to avoid damage to the jujube trees caused by the jujube punching mechanism during the machine's travel, but due to the different maturity periods of different jujubes, there will be Some jujubes will fall on the ground before the picking period, so when picking and collecting jujubes on the tree, the jujubes on the ground should also be collected, but this equipment does not have the function of collecting jujubes on the ground. During the application process, it is necessary to manually collect the fallen dates on the ground, which increases the production cost and labor force, and has no promotional value.

Through the above analysis, it can be seen that the jujube puncher designed by the existing jujube punching machine has a single vibration direction, and it is impossible to realize all-round jujube punching so as to ensure that no dates are leaked during the jujube punching process. Jujube trees within the height range have poor adaptability to jujube trees in different regions; on the other hand, since the jujube puncher cannot perform lateral avoidance movement, it is impossible to adjust the distance according to jujube trees of different sizes, and it is easy to damage the fruit trees during the machine’s travel. In addition, the existing technology generally cannot guarantee that the jujubes on the ground can be completely collected. Due to the different maturity periods of jujubes, in the actual picking process, there will be many jujubes on the ground that need to be manually collected. When the jujube is collected, it is easy to cause damage to the jujube on the ground when the equipment is moving, and it will increase labor and production costs.

Compared with prior art, effective gain of the present invention is:

(1) This equipment has the advantages of high jujube picking rate, strong adaptability, high degree of mechanization, and little damage to fruit trees and jujubes. The jujube picking equipment currently on the market generally does not have the function of collecting jujubes on the ground. This equipment Through the ingenious design of the mechanical structure, the pillow can completely collect the fallen dates on the ground, and at the same time reduce the labor cost, and has a wide application prospect.

(2) Through the combination of bevel gear transmission and lead screw transmission mechanism, the synchronous distance adjustment function of the jujube puncher is realized. The power of the motor can be reversed to the left and right sides through the bevel gear, and through the two driven bevel gears. Connecting the lead screws with the same rotation direction realizes the rectilinear reciprocating motion of the date cutters on the left and right sides in opposite directions. At the same time, the connection between the synchronous nut and the spline sleeve is realized through the use of rolling bearings, which ensures that the nut and the spline sleeve are connected in the actual application process. The key sets can only realize the transmission of horizontal power, but cannot complete the transmission of torque. At the same time, it ensures that the cam can perform horizontal linear reciprocating motion with the jujube cutter at the same time, and then the distance between the date cutters on both sides can be adjusted according to the thickness of the jujube fruit tree. In this way, the damage to the Junzao fruit tree during the movement of the equipment is avoided, and the adaptability of the equipment is improved at the same time, so that the device has a wide application prospect.

(3) The equipment realizes the first-level collection of fallen jujubes by adopting the "eight-shaped" collection sieve, which ensures that the jujubes can be smoothly dropped into the collection box after falling from the tree. The separation of the leaves doped in the Chinese jujube ensures the cleanliness and tidiness during the picking process of the jujube.

(4) This equipment enables the jujube puncher to move up and down during the actual working process by using the vibration device. The preliminary design of the jujube puncher’s movement stroke is 20mm, which ensures that the jujubes on the jujube tree can be picked in all directions and ensure The picking rate of Jun jujube. At the same time, a spring is designed on the top of the jujube punching device to enhance the vibration of the jujube punching device during the jujube hitting process. The jujube punching device is composed of a main rod and several jujube hitting rods, and the jujube hitting rods are fastened vertically in a single row.

The length of the overall single-row rods is different, and the outline is similar to the outline of the jujube tree, which ensures that each jujube rod can be used reasonably and fully. , easy to reach into the jujube tree.

(5) The use of the second-stage jujube collection device ensures that jujubes that have not been collected in the first stage can be completely collected. Because jujubes have different maturity stages, jujubes that mature earlier will generally fall to the ground first. The second-stage jujube collecting device can collect the landed jujubes under the jujube centrifugal drum by using the swash plate, and at the same time, the swash plate of the second-stage jujube collecting device can move along the machine under the action of the linear slide rail. The movement of the frame chute can be avoided according to the size of the jujube trees. Under the action of the spring, the second-stage jujube collecting device can be reset smoothly, so that the jujube falling around the jujube tree can be collected to the centrifugal drum The jujubes below the centrifugal drum will enter the conveyor belt under the centrifugal force of the centrifugal drum to collect the jujubes that have fallen to the ground.

(6) Through the use of linear slide rails, it is ensured that during the actual operation of the equipment, both the jujube beater and the second-stage jujube collection device can be avoided according to the size of the jujube tree. A brush is designed on the side close to the jujube tree. The brush can avoid the thicker trunks and ensure the complete collection of the jujubes dropped by the jujube puncher for the thinner trunks. The jujubes will not fall to the ground along the trunk. The closedness around the trunk is guaranteed, the production efficiency of the equipment is improved, the production cost of the equipment is reduced, and the utility model has wide application prospects.
