Description

a fruit harvester

technical field

The utility model belongs to the technical field of agricultural machinery, in particular to a fruit harvester.

Background technique

In fruit harvesting operations such as citrus or apples, in order not to damage the fruit by bumps, most of them use traditional manual harvesting. The operator holds the fruit to be harvested in one hand and cuts the fruit from the tree with scissors in the other hand. Next, carefully put the harvested fruit into the basket. The work efficiency of this operation method is very low, and because the length of the arm of the person is limited, the operator needs to frequently move the position to pick the fruit, and the operator is prone to fatigue. In addition, citrus trees and apple trees are often relatively tall. When people harvest citrus or apples in the conventional way, they need to use ladders to climb up to work, which is prone to falling accidents. In citrus producing areas, frequent falling accidents that cause people to be disabled occur every year.

The Chinese patent authorization announcement number is CN104584782B, which discloses an anti-collision receiving device for fruit harvesting. It is mainly composed of a bracket and a delivery tube made of cloth hose fixed on the bracket. The delivery tube is spirally wound And be fixed on the support, the fruit receiving inlet of the upper free section of the cloth hose is connected to the harvester head of the fruit harvester, and the lower free section of the cloth hose is connected on the fruit basket. When harvesting citrus or apples, the citrus or apples harvested from the fruit tree enter the upper free section of the fabric hose, and then slowly drop into the fruit basket in a spiral manner along the fabric hose coiled on the support , so as to prevent the citrus or apples from being bumped by tree poles or other objects. Although the "anti-collision receiving device for fruit harvesting" can prevent fruit from colliding, the device needs the help of a driving device to complete picking, and when picking fruit in a relatively dense orchard, it is convenient to use the picking device due to the small gap. Bring a lot of inconvenience.

Including connecting rod 1, harvesting seat 2 and handle 3, connecting rod 1 is connected with handle 3 and harvesting seat 2 respectively; In the inner cavity, the telescopic rod 11 passes through the center of the driving coil 13, one end of the telescopic rod 11 is connected with the harvesting seat 2, the other end of the telescopic rod 11 is fixed on the inner wall of the connecting rod 1, and the driving coil 13 is connected with the outer wall of the connecting rod 1 The harvesting seat 2 is provided with a harvesting head 22, a claw 23 fixedly connected with the harvesting head 22 and a pulley 21 fixed on the harvesting seat 2, and the cavity 24 for accommodating the fruit is formed after the claw 23 is closed; the pulley 21 is provided with a pull cord for controlling the opening and closing of the claw 23, one end of the pull rope is connected with the claw 23, and the other end is connected with the telescopic rod 11; The coil 13 is electrically connected to an electric wire 32, and the other end of the electric wire 32 is connected to a power source.

It should be noted that the picker is not limited to the claw-type fruit grabber, and can also be a fruit setter, a fruit cutter or other forms. Its purpose is to pick the fruit from the tree and place it in a semi-enclosed space. Just make sure the fruit doesn't fall to the ground.

When in use, align the harvesting head 22 with the fruit that needs to be picked, place the fruit in the inner cavity of the claw 23 and press the button switch 31 on the handle 3 with one hand to make the claw 23 close automatically, and finally push the picker The fruit can be picked in the opposite direction of the growth of the fruit and the branches.

The utility model controls the opening and closing of the claws through the button on the handle, which is easy to operate and accurate and flexible for fruit picking. fruit. The harvester effectively solves the inconvenience caused by the orchard growers on ladders or trees, and also greatly reduces the safety hazards of the orchard growers, making it safe and convenient for the orchard growers to pick fruits.

Example 2:

The difference from Embodiment 1 is that the harvesting seat 2 is provided with a return spring for opening the jaws 23 . Pulley 21 is three, is respectively 120 ° and is distributed on the harvesting seat 2, and back-moving spring is three, is respectively fixed on the harvesting seat 2. The telescopic rod 11 is a hollow structure, and the inner cavity of the telescopic rod 11 is provided with at least one pair of magnetic cores 12 , and the magnetic cores 12 are respectively arranged on both sides of the driving coil 13 . The magnetism of the side of the magnetic core 12 close to the driving coil 13 is the same. The claw 23 is made of soft plastic material. Also be provided with handle on the connecting rod 1, handle is fixed on the outer wall of connecting rod 1. The telescopic rod 11 is also provided with a manual telescopic switch.

It should be pointed out that the cross section of the telescopic rod 11, the cavity structure of the connecting rod 1 and the hollow part of the driving coil 13 can be an elliptical cross section or a polygonal cross section; it is preferable to set a shock-absorbing rubber block at the connection between the telescopic rod 11 and the connecting rod 1; The connecting rod 1 is provided with a threading tunnel, and the threading tunnel is isolated from the inner chamber of the connecting rod 1 for the expansion and contraction of the telescopic rod 11, and the connecting wire 32 of the drive coil 13 passes through the threading tunnel; a 6-volt storage battery is used as a harvester The battery supplies power to the drive coil 13 through the drive circuit. The circuit board of the drive circuit is arranged in the handle 3. The power supply wire 32 of the battery enters the handle 3 from the tail of the handle 3 and is connected to the input interface of the drive circuit. The drive circuit The output interface on the top is connected to the input interface of the drive coil 13 by wires.

Then press the button switch 31, and the drive circuit will energize the drive coil 13, so that the front end of the drive coil 13 will generate a magnetic force of the same polarity as the magnetic core 12. core 12, so that the front-end magnetic core 12 moves forward, and at the same time, the rear end of the drive coil 13 produces a magnetic force of opposite polarity to the front end of the rear-end magnetic core 12. According to the principle of opposite sex attraction, the magnetic force at the front end of the drive coil 13 attracts the front end The magnetic core 12 moves forward, and the forward movement of the front-end magnetic core 12 and the rear-end magnetic core 12 drives the telescopic rod 11 to move forward, thereby driving the closing of the claws 23, and pushing the picker to the opposite direction of the fruit and branch growth The fruit can be picked. After the operator takes off the fruit, the drive circuit cuts off the power to the drive coil 13, so that the magnetic force of the drive coil 13 disappears. Under the action of the return spring, the claw 23 is pulled by the pull cord to open, so that the claw 23 returns to the initial state, thereby Drive the telescopic rod 11 to retract backwards so as to harvest the next fruit and vegetable.

The utility model controls the opening and closing of the claws through the button on the handle, which is easy to operate and accurate and flexible for fruit picking. fruit. The harvester effectively solves the inconvenience caused by the orchard growers on ladders or trees, and also greatly reduces the safety hazards of the orchard growers, making it safe and convenient for the orchard growers to pick fruits.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
