Description

Tree-pruning and fruit-picking gun

The utility model is the instrument that a kind of fruit-picking and pollard are used.Name is said and is only to be similar to rifle by rifle, and tool is not pulled the trigger function.

Fruit-picking on taller and bigger fruit tree often need be climbed the tree, ladder or use the stock kinking, and labour intensity is big, and efficient is low.For the fruit tree that is grown in river, lake, the pool and cliff limit, pluck more difficult.Connect the fruit that branch is plucked together for need such as lichee, longan, Calusena lansium in addition, kinking is plucked and can be damaged branch, influences 1 year to bear fruit, and also makes fruit tree that damage by disease and insect takes place easily.

The purpose of this utility model provides a kind of fruit branch of cutting off, the carpopodium that clamping is simultaneously cut off, and the instrument that the fruit of being cut off a handle is not directly fallen, this instrument also can be made pollard and use.

Described Tree-pruning and fruit-picking gun has the pikestaff similar to pistol, and it is all size of 0.3M-5M that its gun barrel has length, regards the industry desired height as, can arbitrarily change the gun barrel of respective length.

The cocking mechanism that slide block is housed in the pikestaff and affects slide block to move backward has pull bar to be connected with slide block in the gun barrel, the gun barrel front end is equipped with the beta pruning clamping device that is affected by pull bar.The machine of trigger is done to be delivered to the beta pruning clamping device by slide block, pull bar, it is finished cut off a handle, and the action of a handle is cut off in clamping.

The beta pruning clamping device has former and later two blades.Back blade does not move by the front end that back tool rest is fixed on gun barrel.Preceding blade is fixed on the front rest, and front rest inserts in the gun barrel and is connected with pull bar.When not pulling trigger, forward and backward blade is pulled trigger at a distance of more than the 1cm, and blade moved backward before pull bar will drive, and tangent staggered with the back blade, finishes shear action.Front plate and rear plate also are housed respectively on forward and backward two blades.Two clamping plate each have spring-loaded, and the phase mutual edge distance of two clamping plate is not identical with the phase mutual edge distance of forward and backward two blades when stressing.Before blade drive front plate when moving and move, when tangent, two clamping plate are adjacent to two blades, when two blades interlock, two clamping plate were adjacent to and compress support spring, lean on the expansion force of support spring, improve the clamping force between two clamping plate.

Cocking mechanism can adopt to the pistol trigger and stir the similar shift fork structure of striker; Also can adopt trigger to affect the structure of pull bar by cable wire; Also can adopt trigger and pull bar to be fastenedly connected, trigger is translation backward, affects the structure of pull bar.

Use described Tree-pruning and fruit-picking gun, needn't ladder, climb the tree, the ground of standing can be finished and be plucked fruit, beta pruning operation on the tall and big tree.As long as its carpopodium length of fruit of being plucked is greater than 2cm, the utility model all is suitable for.Be particularly useful for the harvesting of lichee, longan, Calusena lansium, guava, shaddock, mango, orange, tangerine, pear and other fruits.Its fruit-picking is that the branch handle is cut off, and can not tear the fruit tree branch and influences and bear fruit the coming year, and the carpopodium of cutting off is held, and fruit can not fall, and fruit is put to the appropriate location, unclamps trigger, and clamping plate reset, fruit with pluck the disengaging of fruit rifle.

Below in conjunction with accompanying drawing the utility model is further described.
