Description

High-altitude fruit picker

The invention relates to the technical field of fruit picking appliances, in particular to a high-altitude fruit picking appliance.

Early fruit harvesting was mostly manual picking. For fruits on high-altitude branches, people had to use ladders or climb to the fruit trees to pick them. This not only requires high labor costs, but also low efficiency and high risk.

With the progress of the times, there are currently a variety of more advanced high-altitude picker structures, including fruit picking knives, cables, handles, and net pockets. The movable blades of the fruit picking knives are pulled by the cables to cut and pick the fruits at high places. Take it and drop it into a net bag. Although it allows people to pick fruits on the ground without climbing trees, it improves the efficiency of fruit picking and the safety of labor.

However, the structural design of the existing aerial pickers is not perfect. When operating, you must hold the telescopic rod in one hand, and the other hand must pull the cable to perform the cutting action indirectly to complete the fruit picking operation. It is impossible to use one hand at all. During work, manually keeping the hand-held posture for picking puts a heavy burden on the human body, and the pulling is also quite laborious and the effect is not obvious, especially when the fruit branches grow and extend in different directions. The wind causes the fruit to waver and it is difficult to accurately introduce the fruit stems effectively. The cutting range is cut, and it is difficult to quickly pick the position with an elongated fruit picker.

In view of this, the main purpose of the present invention is to provide a high-altitude fruit picker, which mainly includes: a support base, a cutting knife set, and an elastic reset mechanism:

A mounting part is provided on the support seat to pivotally connect the cutting knife set;

The cutting knife set has at least a first blade and a second blade, which cross each other to form a shearing configuration, and the cutting knife set is provided with a pivot part to be assembled to the mounting part;

The elastic reset mechanism is correspondingly configured on the cutting knife set, so that the first blade and the second blade can be restored to open after cutting.

Preferably, the first blade and the second blade are arranged in an X-shaped cross to form a front slit and a rear slit. The front slit and the rear slit are arranged opposite to each other, but they are not Limited by this.

In a preferred implementation, each of the slits has a movable V-shaped guiding portion and a U-shaped cutting portion connected to the tail end of the V-shaped guiding portion, but the actual situation is not limited to this.

Preferably, one end of the support base is provided with a post portion for connecting an elongated rod body, and a plurality of hooks are further provided under the support base for attaching a net bag for fruit picking and storage, but in reality Not limited to this.

The overall structure design is simple and practical, so that the support seat can be pushed and pulled deformed when it is stressed, and at the same time the cutting knife set is driven to shear. A movable V-shaped guide part in the cutting mouth can be used ingeniously to guide the high-altitude fruit homeopathically. Gradually shrink and close the mouth, pinch the limit in a U-shaped cutting part, using the principle of leverage to make the force ingeniously combined, and even can be operated with one hand, which can effectively and accurately cut the fruit pedicle from the support A net bag for fruit picking is attached under the seat to quickly complete fruit picking operations and improve picking efficiency.

In order to facilitate the understanding of the content of the present invention and the effects that can be achieved, specific embodiments are listed in conjunction with the drawings. The detailed description is as follows: Please refer to Figures 1 to 4, which is a high-altitude fruit picker provided by the present invention. , Mainly includes: a support seat 1, a cutting knife set 2, and an elastic reset mechanism 3.

The elastic reset mechanism 3 is correspondingly configured on the cutting knife set 2, so that the first blade 21 and the second blade 22 can be restored to open after shearing.

Preferably, the first blade 21 and the second blade 22 are arranged in an X-shaped cross to form a front slit 24 and a rear slit 25, and the front slit 24 and the rear slit 25 are opposite to each other. Set, but the actual is not limited to this.

Preferably, the front cutting opening 24 or the rear cutting opening 25 has a movable V-shaped guiding portion 201 and a U-shaped cutting portion 202 connected to the tail end of the V-shaped guiding portion 201, wherein the V The guiding portion 201 may be provided in a shape without a sharp edge, and the U-shaped cutting portion 202 may be provided in a sharp shape, but it is not limited in practice.

In a preferred implementation, as shown in Figures 1 to 4, the supporting base 1 is more specifically composed of a large frame 100, and a rail 101 is provided on the left and right sides of the support seat. There are three transverse members 102, 103, 104 on the middle and lower spacer pivots, so that the big frame 100 is divided into two small frames, namely the front frame part 124 and the rear frame part 125, which can be pushed and pulled deformed under force;

Preferably, the mounting portion 11 is arranged on the middle cross member 103 of the large frame 100, so that when the cutting knife set 2 forms an X-shaped configuration, the front slit 24 is correspondingly arranged on the front frame portion 124, and the The rear cutting opening 25 is correspondingly arranged on the rear frame 125;

In a preferred implementation, the elastic reset mechanism 3 is composed of two springs 301 and 302, and the first blade 21 and the second blade 22 of the cutting knife set 2 are each provided with a fork 230 on the back of the two ends. The springs 301 and 302 are hooked and arranged on the left and right sides of the cutting knife set 2 in parallel, but they are not limited to this.

In a preferred implementation, a plurality of hooks 18 are further provided under the support base 1 to attach a net bag 8 for fruit picking and storage.

In a preferred implementation, one end of the support base 1 is provided with a post portion 19 for connecting and setting an elongated pole body 9.

The overall structure combination is simple and seemingly ordinary, but the design is reasonable and practical. In particular, the VU-shaped design on the cutting knife set 2 is the most distinctive feature of the fruit picker of the present invention. In application, the support base 1 can be pushed and pulled deformed when subjected to force, and the cutting knife set 2 is driven to cut at the same time. The movable V-shaped guide part 201 in the front cutting opening 24 and the rear cutting opening 25 is used cleverly to bring the high-altitude fruit homeopathically. The U-shaped cutting part 202 is guided, gradually retracted, and pinched in the U-shaped cutting part 202. The lever is used to make the force ingeniously combined. It can even be operated with one hand, which can effectively cut the fruit accurately and neatly. A net bag 8 for fruit picking is attached to the stalk under the support base 1, to quickly complete fruit picking operations and improve picking efficiency.

In fact, the high-altitude fruit picker of the present invention has two operation modes: 1. a front-up push type and 2. a rear pull-down type. The operation methods of the two are roughly the same.

1. Front-up push operation method: Use the front frame portion 124 of the support 1 to insert the fruit, and then use the front cutting opening 24 of the cutting knife set 2 to cut the fruit, and the fruit stalk can be easily cut Break into the net bag 8.

2. Rear pull-down operation method: Use the rear frame 125 of the support 1 to insert the fruit, and then pull the rear cutting opening 25 of the cutting knife set 2 for cutting, and the fruit stalk can be easily cut off Drop into the net bag 8.

As shown in Figures 1 to 5A-5D, the following only uses the rear pull-down operation to explain the entire picking process of the high-altitude fruit picker of the present invention in detail:

First, use the rear cutting opening 25 of the support base 1 to select the fruit to be inserted, and then pull it back to use the movable V-shaped guide part 201 in the rear cutting opening 25 to introduce the high-altitude fruit stems into the U-shaped cutting part 202 ( Fig. 5A), pull the fruit picker with force, even with one hand, use the lever principle to leverage the force to combine the force ingeniously. At this time, the large frame 100 of the support base 1 will be pulled and tilted, and at the same time The cutting knife set 2 is also driven to produce a continuous motion to play a shearing effect.

When the large frame 100 is inclined from 0 degrees to about 22.5 degrees, the cutting knife set 2 is also linked to change its corresponding angle. At this time, the U-shaped cutting portion 202 will first become a conical closing shape with a large belly and a small mouth ( Figure 5B), use the forceps to pinch the fruit pedicle, so that the pedicle will not slip off and be restricted to the cutting range. With the continuous change and reduction of the angle related to the back pulling force, the U-shaped cut portion 202 will become a smaller teardrop shape (Figure 5C). At this moment, the fruit pedicle will be cut off by about 80% of its diameter.

When the big frame 100, the inclination angle continues to shrink, and the cutting knife set 2 in it is driven by leverage and force to continue to reduce the inclination angle to the limit of about 45 degrees, so that the U-shaped cutting portion 202 becomes completely closed. The state of the type (5D diagram). The whole components play their due role in succession, so the last 20% of the fruit stalks are forced to break instantly. The entire cutting process can be completed in only about 2 seconds, and the fruit will naturally fall into the net bag 8 inside.

After the fruit is harvested, due to the disappearance of the relative pulling force of the lever fulcrum, the support base 1 and the cutting knife set 2 are restored to their original state under the action of the elastic reset mechanism 3, and the entire rear pull-down operation is completed to wait for the next fruit picking action. The same front push-up operation method of the present invention is the same as this type, and will not be repeated here.

The characteristics of the high-altitude fruit picker of the present invention include a support seat that is easy to carry and store, a hidden cutting knife set 2, an elastic reset mechanism 3, a blunt face upside-down V-shaped guide part 201, and a sharp upside-down U-shaped cutting part 202. Various exquisite and practical designs such as special hook-and-hook net bag 8, movable extension rod body 9 and so on, the composition is simple in structure, low in cost, and easy to manufacture. It is very conducive to the future promotion of the product. It can solve the problem of too large and difficult-to-harvest causal trees for fruit farmers and the industry, and increase the willingness of fruit farmers to plant large-scale fruit trees. At the same time, it also responds to the government's promotion of afforestation and lungs, greening the environment, and purifying the air. The purpose of promoting an environmentally friendly life.

In summary, the novelty and practicality of the present invention fully meets the requirements of the patent, and an application for a patent for invention is filed.
