Embodiment 1

[0032] Embodiment 1: For the tree stump that wood is softer and has certain length on the ground surface, select A type grasping device (such as Image 6 , 7 , Shown in 8, 9) cooperate with tripod and hydraulic cylinder to use, and the contact area of ​​this grabbing device and stump is larger.

Embodiment 2

[0033] Embodiment 2: For the tree stump that wood is harder and has certain length on the ground surface, select B type grasping device (such as Figure 10 , 11 , shown in 12 and 13) are used in conjunction with tripod and hydraulic cylinder, and the contact area of ​​this grabbing device and tree stump is little, and the pressure is strong and it is easier to grasp tree stump firmly.

Embodiment 3

[0034] Embodiment 3: For tree stumps with no exposed parts above the ground, use a C-type grasping device to cooperate with a tripod and a hydraulic cylinder. The left and right grippers are driven into the ground and hug the tree stump tightly.

Abstract

The invention relates to a stump lifting device comprising a tripod, a hydraulic cylinder (1) and a gripping device. The hydraulic cylinder is arranged at the top end of the tripod, and an extension bar of the hydraulic cylinder is connected with the gripping device through a steel wire rope. When in work, the hydraulic cylinder is driven to make the extension bar of the hydraulic cylinder run upwards, and a stump is tightly clasped and lifted by the gripping device. The device can reduce the labor intensity of people in the stump digging process.

Description

technical field [0001] The invention is a tree stump lifting device, which belongs to the field of machinery. Background technique [0002] At present, after the trees have grown into talents, the trees are generally sawed off from the roots first, and then the stumps are dug out. Planing tree stumps consumes a lot of manpower and material resources, usually three or four people planing a day. I saw a machine for pulling rubber trees on the Internet, but it has to be used with a tractor, the structure is complicated and the cost is high, so it has not been popularized. Contents of the invention [0003] In order to reduce the labor intensity of people when planing tree stumps and improve production efficiency, the invention provides a tree stump lifting device. [0004] The technical solution adopted for solving the technical problem is: the stump lifting device comprises a tripod, a hydraulic cylinder (1) and a grabbing device. The tripod is made up of suspension plate...
