Abstract

The utility model relates to a fruit picking device which comprises a long rod. The fruit picking device is characterized in that the long rod is a sleeve tube, the top end of which is provided with a bowl-shaped piece, and the center of the bottom of the bowl-shaped piece is provided with a hole. A push rod arranged inside the sleeve tube is matched with the sleeve tube in a sliding way, and the upper part of the push rod is provided with a shaft which is matched with the central hole at the bottom of the bowl-shaped piece in a sliding way, wherein, the shaft is provided with a pressure spring, and the upper part of the shaft is provided with a threaded shaft which has a smaller diameter than the shaft and is arranged inside a hole at the bottom of a fruit grabbing claw arranged inside the bowl-shaped piece; nuts are used for fixing the elastic fruit grabbing claw with the push rod, and the inner surface of an elastic arc strip of the fruit grabbing claw is provided with a soft layer. The utility model can pick fruits which grow at the place that hand can not reach without damaging the fruits.

Description

Fruit picking apparatus

The utility model belongs to a kind of fruit picking instrument, is applicable to the results of fruit.

To the higher fruit tree that grows, as pear tree, apple tree etc., when plucking the fruit at fruit tree top, how to knock fruit branch with stock, fruit is shaken this method easy damaged fruit.

The purpose of this utility model provide a kind of can handle pluck less than fruit remove and don't damage the fruit picking apparatus of fruit.

Task of the present utility model is to realize like this, it comprises a stock, it is characterized in that: stock is a sleeve pipe, there is a bowl on its top, the bottom centre of bowl opens a hole, be provided with push rod in the sleeve pipe and sleeve pipe is slidingly matched, push rod top has a centre bore with the bowl bottom to be slidingly matched, on the axle compression spring is arranged, axle top has a thread spindle littler than its diameter to place in the interior elasticity fruit graping claw base apertures of bowl, with nut elasticity fruit graping claw and push rod are fixed as one, on the inner surface of the flexible arc bar of fruit graping claw, are provided with soft layer.

The utility model has been owing to taked the elasticity fruit graping claw, fruit beyond reach can be taken off and do not damage fruit, therefore, compared with prior art, has tangible advantage.

Fig. 1 is the structural representation of fruit picking apparatus.

Description of drawings: 1. push rod 2. sleeve pipes 3. compression springs 4. nuts 5. elasticity fruit graping claws

In conjunction with above accompanying drawing embodiment of the present utility model is described further.

One step axle is arranged at the top of push rod 1, and a thread spindle littler than its diameter arranged at step axle top, and push rod 1 places in the hole of sleeve pipe 2 lower ends, can in the hole, slide, establish a compression spring 3 on the step axle, slidably, there is a bowl upper end of sleeve pipe 2 to the step axle in sleeve pipe 2 upper end holes.The structure of elasticity fruit graping claw 5 is uniform three arc resilient metal strips on a disk, and the center of disk is porose, is enclosed within on the thread spindle of push rod, with nut itself and push rod is fixed as one.The elasticity fruit graping claw can be opened or shrink by the restriction of bowl-type in bowl.The elastic force size of spring should be suitable, excessive fruit may being crushed, and elastic force is little when plucking fruit because clamping force is not enough, and fruit skids off from fruit graping claw and plucks to fall fruit.On the inner surface of arc resilient metal strip, paste soft layer just like felt.When plucking fruit with this picking device, a hand-held sleeve pipe, another manual operating push rod upwards slides, the arc resilient metal strip of elasticity fruit graping claw moves on bowl, mouthful magnifying of fruit graping claw when fruit enters in the elastic claw of fruit picking device, stops the thrust to push rod, this moment, compression spring made push rod to moving down, fruit picking device is retracted by the restriction of bowl, and fruit is clamped, and hand-held sleeve pipe pulls down, rotating casing can be removed fruit simultaneously.Fruit picking device is promoted push rod after containing the fruit case, fruit is promptly put into the fruit case.The length of sleeve pipe and push rod can be made into variable flexible trombone slide structure.The arc elastic strip is selected the material manufacturing of good springiness, as metal or engineering plastics.
