Technical Field

The invention relates to the technical field of lifting machinery, in particular to a fruit picking ladder capable of preventing fruit from sliding off.

Background

The lifting means the meaning of ascending a height and descending, can adjust device's height, and in the life, the elevation structure all can be used in many places, often all can combine other devices to use together. For example, when vertical transportation is performed in logistics systems such as factories and automated warehouses, various plane transportation devices are often installed on the lifting platform as connection devices for transportation lines with different heights. Fruit need pick after ripe, but the height that different fruit grows is different, consequently needs the ladder to make things convenient for the staff to pick the fruit of eminence.

current ladder is at the picking in-process, because the slope of staff's body or other limbs action for the ladder appears sliding with the contact position on ground, can lead to the staff to fall from the ladder, cause the health harm, moreover, current ladder all is fixed height usually, can only use in injecing the height, otherwise just need add the backing plate and increase the height, just can adapt to the not fruit tree of co-altitude, can cause the waste in time for the picking work of fruit, and the structure is unstable, cause the harm of fruit easily.

Disclosure of Invention

In order to realize the purposes of strengthening the ground gripping force of the ladder, avoiding the ladder from slipping off and enabling the ladder to adapt to fruit trees with different heights, the invention provides the following technical scheme: the utility model provides a can prevent ladder is picked to fruit of landing, includes PMKD, PMKD's left side upper end is rotated and is installed the lifter, the upper end fixed mounting of lifter has the roof, it is connected with extension ladder to rotate between the right side of roof and PMKD's the right side, the movable rod has been cup jointed in both ends activity about PMKD's inside, the lower extreme fixed mounting of movable rod has the fixed disk, the outside movable mounting of fixed disk has the stationary dog, the lower extreme intermediate position fixed mounting of fixed disk has the spud pile, extension ladder can stretch out and draw back, can adjust the height of ladder, can conveniently pick the fruit of higher position department.

Preferably, the outer sides of the lifting rod and the extension ladder are both rotatably provided with fixed seats, and a limiting spring is fixedly connected between the fixed seats.

Preferably, the fixed shaft is fixedly mounted on the outer side of the fixed disc, the fixed claws are rotatably mounted on the outer side of the fixed shaft, and the fixed claws have good ground grabbing force, so that the ladder can be well fixed on the ground.

Preferably, guardrails are fixedly mounted on two sides of the outer side of the interior of the extension ladder.

preferably, the inner loop bar is movably sleeved inside the extension ladder, and the upper end of the extension ladder is provided with a clamping groove.

Preferably, a fixed spring located in the stabilizing groove is fixedly mounted on the left side of the inner loop bar, a bayonet lock is fixedly connected to the upper end of the fixed spring, and the bayonet lock is matched with the clamping groove.

Preferably, a clamping plate is fixedly mounted on the left side of the top plate, the right end of the clamping plate penetrates through the left wall of the top plate and is in meshed connection with the upper end of the rotating connecting rod, the lower end of the rotating connecting rod is in meshed connection with a fixed connecting rod, and the right end of the fixed connecting rod is in meshed connection with the rear end of the rotating gear.

the invention has the beneficial effects that:

1. Through the arrangement of the fixed claws, when the ladder is installed, when the clamping plate is in contact with a fruit tree, the clamping plate is enabled to move towards the inside of the top plate through pressing, and further through the transmission action of the rotating connecting rod and the fixed connecting rod, the rotation of the rotating gear can be driven, and further through the transmission action of the transmission rod, the movable rod can move towards the outer side of the fixed bottom plate under the action of the transmission rod, so that a fixed pile fixedly installed at the lower end of the fixed disc can be tightly inserted into the ground, meanwhile, the fixed claws on the outer side of the fixed disc can have good ground gripping force, the ladder can be fixed after being in contact with the fruit tree, the fixed claws can be well fixed with the ground, and workers can be prevented from sliding down to cause personnel damage in; simultaneously through the inside inner loop pole of extension ladder make the extension ladder can obtain tensile, match each other between the bayonet lock through inner loop pole outside movable mounting and the draw-in groove that the extension ladder surface was seted up simultaneously for the extension ladder can adjust different heights, and then makes the extension ladder can adapt to the fruit tree of co-altitude not, can make things convenient for the staff to carry out the picking work of fruit to the fruit tree of co-altitude not.

2. Through the setting of injecing the spring, when not using the ladder, through the rotation of fixing base for the extension ladder takes place to rotate, makes the extension ladder can be parallel with the lifter, and then PMKD presents vertical state through rotating, makes the ladder can carry out fine regulation, can be better deposit the processing to the ladder, can practice thrift more spaces.
