Description

Crank and connecting rod gear cutter

The present invention relates to a device for picking fruits and cutting leaves, and in particular to a crank-link gear cutter for palm fruit picking and foliage trimming.

The palm oil industry is a pillar industry in Thailand and Southeast Asian countries. As a raw material for palm oil production, palm fruit, grown on 3-5 meters of palm trees, traditional palm fruit picking and foliage pruning methods are carried out by farmers holding a shovel weighing about 4,000 grams. This method of operation is labor intensive and has low production efficiency. At the same time, the operator is required to be cautious when working, otherwise it is easy to damage the palm trees, causing the palm fruit to reduce production or even the death of palm trees. Injured palm trees tend to get sick from the scars, causing decay, which can lead to the death of palm trees. Therefore, safe, efficient and versatile palm fruit picking and foliage pruning machines or tools are urgently needed by farmers in palm plantations.

In order to solve the above problems, the present invention provides a mechanized tool for palm fruit picking and leaf trimming, which is flexible in operation, accurate in positioning, safe and reliable, and has high efficiency in picking and trimming, which reduces the labor intensity of the operator and reduces the labor cost. Reduces the damage that palm trees can suffer.

According to the technical solution of the present invention, a palm fruit picking and leaf trimming tool includes a cutter and a cutter driving mechanism; the cutter is mounted on a top end of the cutter bar, and the lower end of the cutter bar is small through a cutter pin and a bearing and a connecting rod The head end is connected, and the big end of the connecting rod is mounted to the crank journal of the crankshaft through a needle bearing. The driven gear is fixedly mounted on the main journal of the crankshaft, and a key is arranged between the main journal and the driven gear; the crank is mounted on the crankshaft The crankshaft, the crank and the connecting rod are combined into a crank-link mechanism, which can convert the rotary motion of the driven gear into a linear reciprocating motion of the cutter bar; the crankshaft and the crankshaft of the crank are mounted with the bearing and then integrally mounted into the casing. The driving gear is mounted on the bearing and the retaining ring and then loaded into the casing, and is inserted into the hole with a circlip; the driving gear meshes with the driven gear, and the driving gear is perpendicular to the axis of the driven gear.

A bushing is arranged between the arbor and the box body, and a circlip for the hole is arranged outside the sleeve, an oil seal is arranged between the arbor and the box, and a guide pin inserted through the box is arranged in the waist hole of the arbor. The guide pin head has a fixing nut.

A positioning pin is arranged on the box body to ensure accurate position when the cover plate is installed, a sealing gasket is arranged between the box body and the cover plate, the cover plate is fixed on the box body by screws, and the crank link gear cutter is integrally mounted to the lawn mower Or on the post of the high-end chain saw, fasten with screws.

The specific implementation of the present creation will be further described below with reference to the accompanying drawings.

In the first figure, the tool 1, the nut 2, the cutter rod 3, the screw 4, the oil seal 5, the circlip for the hole 6, the sleeve 7, the nut 8, the screw 9, the screw plug 10, the cutter pin 11, and the casing 12. The driving gear 13, the bearing 14, the circlip for the shaft 15, the circlip for the hole 16, the screw 17, the guide pin 18, the positioning pin 19, the circlip for the shaft 20, the positioning pin 21, the bearing 22, and the driven Gear 23, crankshaft 24, key 25, needle bearing 26, bearing 27, link 28, crank 29, bearing 30, washer 31, cover plate 32, screw 33, and the like.

As shown in the first figure, this creation is a palm fruit picking and foliage trimming tool, including the cutter 1 and the cutter drive mechanism.

The cutter 1 may be a sickle shape, a zigzag shape or a blade shape, and is mounted on the top end of the cutter bar 3 by screws 4, the nut 2 locks the screw 4, and the cutter bar 3 is slidably fitted in the sleeve 7 of the casing 12, and the cutter drive mechanism It is installed in the casing 12.

The tool drive mechanism includes an intermeshing drive gear 13 and a driven gear 23 mounted in the casing 12, one end of which is connected to the cutter 1 and the other end is fixed to the mast of the lawn mower or the high-end chain saw (see The second picture).

After the driving gear 13 is mounted on the bearing 14, the circlip 15 for the shaft is mounted, and then integrally mounted into the casing 12, and the driving gear 13 is connected with the driving shaft in the stalk of the lawn mower or the high-end chain saw. The moving gear 23 is fixedly mounted on the main journal of the crankshaft 24. The crankshaft 24, the needle bearing 26, the connecting rod 28 and the crank 29 are combined into a crank connecting rod mechanism, and the crank connecting rod mechanism is mounted in the box through the bearing 22 and the bearing 30. In the body 12, the small end of the connecting rod 28 is connected to the shank 3 via a bearing 27 and a shank pin 11.

The working principle of the creation is as follows: the crank connecting rod gear cutter is mounted on the lawn mower or the high-saw oil sawing pole, the driving shaft in the connecting rod is connected with the driving gear 13, the driving shaft rotates, and the driving gear 13 and the driven gear are driven. 23 rotation, the crank link mechanism fixedly coupled with the driven gear 23 converts the rotary motion of the driven gear 23 into a linear reciprocating motion of the cutter bar 3, so that the cutter mounted on the cutter bar 3 cuts the palm fruit and the leaves, and is completed. Palm fruit picking and foliage pruning work.

The creation has the following advantages: the movement design of the gear rotation and the crank linkage mechanism is adopted, and the movement and power transmission of the engine and the motor are effectively realized, that is, the rotary motion of the engine or the electric motor is converted into the linear reciprocating motion of the cutter 1; The driving gear 13 and the driven gear 23 rotate perpendicularly, and the rotational motion of the crank gear mechanism is converted into a linear reciprocating motion of the cutter bar 3; by scientific design, the driven gear 23 and the crank connecting rod mechanism are The motion system can achieve better dynamic balance, thereby reducing the vibration and noise of the machine; the coaxial gear design of the driving gear 13 and the cutter bar 3 makes the machine operator feel comfortable and labor-saving.

This creation can be easily installed on most lawn mowers and high-saw chainsaws sold on the market. Palm fruit picking and foliage trimming can be accomplished with the power provided by the engine or electric motor to achieve lawn mower or high-powder oil. A machine for sawing is more versatile. The utility model has the advantages of compact structure, light weight, flexible operation, accurate positioning, safety and reliability, convenient use and maintenance, and the utility model can effectively reduce the impact wound on the palm tree during work. The tool head can be flexibly replaced according to the needs of the work and used for machines of other tree species.

This creation is ergonomically designed to greatly reduce labor intensity and improve driving efficiency.
