Description

Technical Field

[0001] The utility model relates to the technical field of forestry picking, in particular to a forestry picking device with adjustable height. Background Art

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. It is an important part of the national economy. The trees planted in the forestry industry also include fruit trees. Planting fruit forests on the mountains can not only protect the environment and prevent soil erosion, but also increase farmers' income. When the fruits on the fruit trees are ripe, they need to be picked from the trees or fruit racks. Since many fruit trees are tall, the fruits on the trees cannot be picked directly. You can use the hook on the picking rod to hook the fruit stalk, and then pull the fruit down hard to make the fruit fall.

[0003] The utility model patent with the authorization announcement number CN214508056U discloses "A high-altitude apple picking scissors", which includes a first picking rod, a second picking rod, a first picking blade and a second picking blade, wherein the first picking rod and the second picking rod are rotatably connected, and the first picking blade and the second picking blade are respectively fixed to one end of the first picking rod and the second picking rod; an apple collecting mechanism is installed on the top of the first picking rod, and the apple collecting mechanism includes a collecting box and a supporting plate, a card slot is provided on the supporting plate, a slider slidably connected to the card slot is fixed on the collecting box, and a lifting component driving the collecting box is installed on the supporting plate. The high-altitude apple picking scissors are reasonably designed and suitable for picking fruits in higher places, avoiding apples from falling directly after picking and thus causing damage to the apples.

[0004] However, the above-mentioned prior art solutions still have the following deficiencies: the first picking rod cannot be adjusted, and fruits at different heights cannot be picked, which has great limitations. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a height-adjustable forestry picking device, which can be adjusted according to the height of the fruit, making it easy to pick fruits at different heights and greatly reducing the limitations during picking.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A height-adjustable forestry picking device comprises an outer support rod, a screw rod is arranged inside the outer support rod, a telescopic rod is threadedly connected to the surface of the screw rod, and a mounting plate is fixedly connected to the top of the telescopic rod;

[0008] The bottom of the screw rod movably passes through the outer support rod and is fixedly connected with a handle, the two ends of the telescopic rod are respectively fixedly connected with a limited sliding block, and the left and right inner walls of the outer support rod are respectively provided with sliding grooves.

[0009] Preferably, the telescopic rod is slidably disposed in the outer support rod, and the limit sliding blocks are slidably disposed in the sliding grooves respectively.

[0010] Preferably, the outer surface of the bottom of the outer support rod is covered with a first protective sleeve, and the surface of the first protective sleeve is covered with an anti-slip ring.

[0011] Preferably, a first picking rod is rotatably provided on the left side of the outer support rod, a second picking rod is slidably inserted on the top of the first picking rod, and a top plate is fixedly connected to the top of the second picking rod.

[0012] Preferably, a picking knife is fixedly connected to the right side of the top plate, a sliding rod is fixedly connected to the bottom of the top plate, and an arc-shaped sliding sheet is fixedly connected to the bottom of the sliding rod.

[0013] Preferably, a bracket is fixedly connected to the right side of the mounting plate, and a collecting bag is fixedly connected to the right side of the bracket.

[0014] Preferably, a semicircular limiting block is fixedly connected to the top of the mounting plate, and an arc-shaped sliding groove is provided on the outer surface of the semicircular limiting block, and the arc-shaped sliding groove is adapted to the arc-shaped sliding sheet.

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0016] First, by turning the handle, the screw rod can be rotated, thereby driving the telescopic rod to slide upward in the outer support rod. At the same time, the limit sliders at both ends of the telescopic rod slide in the slide groove respectively to limit the telescopic rod, so that the telescopic rod can move upward normally, and the mounting plate can be moved upward, and then it can be adjusted according to the height of the fruit, which is convenient for picking fruits at different heights, greatly reducing the limitations during picking.

[0017] Secondly, the first protective cover arranged on the outer support rod ensures the comfort of the pickers when holding the picker, and prevents the pickers from wearing the picker's hands. The sliding rod and the arc-shaped slide plate are arranged so that when the top plate rotates, the arc-shaped slide plate slides along the arc-shaped slide groove of the semicircular limit block, ensuring that the picker can perform cutting work according to the predetermined trajectory.
