Description

An orchard operation lifting platform with automatic leveling function

technical field

The utility model relates to a novel orchard operation lifting platform, which belongs to the field of lifting equipment.

Background technique

my country is currently one of the world's largest producers and consumers of forest fruits. Improving the efficiency of forest fruit picking is of great significance to the level of my country's forest fruit industrialization and the economic income of Chinese fruit farmers. The operating conditions and requirements of orchards are special. Generally, the fruit trees are relatively low and the planting is relatively dense. Most of the fruits need to be picked at a certain height from the ground, which makes the operation difficult and intensive. At the same time, fruit trees are mostly planted on hillsides and hilly areas. The road conditions are poor and the terrain is undulating. This directly leads to low fruit picking efficiency, and it is difficult to realize large-scale mechanized operations. Therefore, it is particularly important to design a lifting platform that can meet the safe use of fruit farmers, reduce the labor intensity of personnel, and improve the picking rate.

At present, the orchard operation lifting platform on the market generally adopts the scissor lift, which has the advantages of large carrying capacity and large working range at height, but at the same time it has many disadvantages, as follows:

1. When most orchard work platforms encounter rough and undulating roads, the lifting platform will tilt to a certain extent. This will make the operating personnel picking on the platform work tense, easily tired, and the picking efficiency is low.

2. Generally, fruit trees are relatively low and do not require a large lifting height, while the scissor lifts on the market are generally composed of multi-section lifting arms, the lifting distance is large, and the increase in the number of pole layers will lead to poor stability of the lift , Rollover may occur, and maintenance is more complicated.

3. The scissor lift is generally directly fixed to the middle of the lifting arm by a cross bar, so that the current scissor lift can only be lifted vertically to the chassis of the car without leveling function. When encountering uneven roads such as mountains and forests, the shift of the center of gravity may cause the danger of overturning during the lifting process, threatening the safety of operators.

At present, most picking lifting platforms do not have a leveling function, and operators are prone to instability. In addition, the aging structure of fruit farmers in my country is becoming more and more obvious, and the safety of picking is poor. Therefore, there is an urgent need for an orchard operation lifting platform machine that can automatically level the operation platform to improve the picking efficiency, thereby ensuring the safety of the operators.

Contents of the invention

The lower end of the lifting arm is equipped with a pulley and can slide on the track of the carrying device; The rod passes through the long slot of the support frame to connect the lifting arms on both sides, and the cross bar slides in the long slot of the lifting arm and support frame with the movement of the lifting arm; when lifting, the cross bar slides in the slot of the lifting arm and support frame Sliding inside plays the role of limitation and support; the working platform is fixed on the slewing bearing below by bolts, and guardrails are installed on the upper part of the working platform.

The direction leveling device is composed of a three-phase hybrid stepping motor, a base plate, a gear, and a slewing bearing; the three-phase hybrid stepping motor is fixed on the lower part of the base plate through bolts, which can drive the gear on the upper part of the base plate to rotate, and the gear It meshes with the slewing bearing under the work platform to drive the work platform to rotate.

The telescopic hydraulic cylinder is installed on the carrying device, one end is connected and fixed in the middle of the carrying device through a hinge, and the other end is connected to the lower end of the lifting arm through a hinge; thus the telescopic movement of the telescopic hydraulic cylinder can drive the inner and outer lifting arms Movement on carrier rails. By controlling the telescopic length of the two telescopic hydraulic cylinders and allowing the two telescopic hydraulic cylinders to cooperate with each other to achieve different heights and angles of the work platform, and to complete the leveling function is the core of this design.

The dual-axis inclination sensor is used to collect the tilt angle of the platform, transmit the collected data to the control center and then process the signal, and turn it into an output signal to control the expansion and contraction of the hydraulic cylinder and the three-phase hybrid stepping motor. turn.

Compared with the prior art, the present invention has the following advantages:

1. The lifting arm is redesigned. There is a long slot in the middle of the lifting arm. The cross bar passes through the long slot and can slide in the slot when lifting. Change the telescopic hydraulic cylinder to be connected to the lower end of the lifting arm for horizontal push, so that the length of the lifting arm is fully utilized, and the lifting range is larger;

2. One end of the telescopic hydraulic cylinder is connected to the lower end of the lifting arm for horizontal telescopic movement, and the adjustment is more rapid and convenient.

3. The operating platform on which the operator stands can be turned freely at 360 degrees, which is convenient for the orchard operating lifting platform to pass through the woodland.

4. The orchard operation lifting platform has an automatic leveling function for the direction and angle. When the orchard operation lifting platform tilts to a certain angle, the leveling system will send out an alarm, and the leveling work will be carried out in time. In this way, the stability of the orchard operation lifting platform and the safety and comfort of the operators are improved, and the picking efficiency of forest fruits is improved.
