The effects of saving time and labor and being high in excavating speed and easy to operate are achieved, the air cylinder stretches out and draws back, a breaking hammer is driven to continuously break ores, meanwhile, an excavating hoe continuously excavates the ores, and the two actions can be finished at the same time.

The invention relates to a sweep-saw type tree mover. The tree mover is characterized in that the tree mover comprises a base (1); a handrail (1a) is arranged on the base (1); the lower part of the base (1) is connected with wheels (1b); a power machine (5), a driving device, a rotary handle (9), a saw fixing ring (13), a saw blade (14), matched sliding wheels and pulling wires (10) are arranged on the base; and the pulling wires (10) are connected with the sliding wheels. The invention has the following advantages: (1) the sweep-saw type tree mover has small size and convenient and rapid operation and can remove the seedling with soil balls from small spaces in which the large and medium machinery can not enter; (2) the completeness of the soil ball can be ensured, thereby avoiding the loss due to the damage of the soil balls; (3) the seedling can be quickly moved in time, the seedling can maintain fresh, and the survival rate can be enhanced; (4) the size of the moved seedling soil ball is same, and the shape is uniform, thereby being convenient for package and transportation; (5) the labor efficiency can be greatly enhanced, thereby saving a great amount of labor and moving cost.

The invention relates to a digging and transporting device, particularly relates to a stable building waste digging and transporting device and aims to provide a stable building waste digging and transporting device with high digging and transporting efficiency. The stable building waste digging and transporting device comprises a trolley, a first oscillating rod, a first sliding block, a connection rod, a third sliding block, a first sliding rail, a digging bucket, a first rotating motor, a third oscillating rod, a support rod, a first elastic component, a pressing rod, a guide hole, a fixed baffle block, a contact rolling wheel, a second rotating motor, a cam wheel, a guide plate, a bracket, a second elastic component, a lifting rod, a connection block, a second oscillating rod, a second sliding block and a second sliding rail, wherein the trolley is arranged on the ground; the bracket is arranged at the top of the trolley. The stable building waste digging and transporting device achieves the effects of rapid digging and transporting speed, high digging and transporting efficiency, long service life and simple operation.

The invention discloses a drum-type jacking excavator, which comprises a cylinder body, a cylinder group arranged on the front panel of the cylinder body, and a soil conveyor belt fixed in the cylinder body; The upper roller and the lower roller, the two ends of the rotating shafts of the upper roller and the lower roller are respectively connected to the left and right side walls of the cylinder; the surface of the upper roller is equipped with evenly distributed upper scrapers, and the surface of the lower roller is equipped with evenly distributed lower scrapers and upper scrapers. There is a gap between the scraper and the lower scraper; the soil conveyor belt is set close to the junction of the upper scraper and the lower scraper. The beneficial effects of the invention are: through the cooperation of the drill and the scraper, the soil-breaking ability is greatly strengthened, the excavation speed is fast, the jacking operation efficiency is high, the degree of automation is high, and the amount of manual labor is reduced.

The invention discloses a seedling transplanting device. The seedling transplanting device comprises an operation platform, and four rectangular running wheels are installed on the lower side wall ofthe operation platform. The seedling transplanting device has the advantages that the inclination angle of digging plates and the distance between the two digging plates can be adjusted according to the specific growth condition of seedlings, and the adaptability is high; the seedlings can be righted in the digging process through a righting soft cushion and effectively prevented from the risks ofdeviation and even breakage; by adopting a non-labor digging mode, the time and labor are saved, the speeding of digging the seedlings is high, and the efficiency is high.

The invention discloses a natural energy uninterrupted cooling pit-digging device used for tree planting. When the device provided by the invention is used, a pit digging depth is controlled by upperlimit sleeves and lower limit sleeves, a rotation shaft is prevented from shifting through a balance component, a probe cone part is firstly in contact with soil to open the soil, so that a pit digging speed is improved, and abrasion of a spiral blade is effectively reduced; in the falling process of the rotation shaft, the lower part of a spring protective cover is in contact with the ground andgradually compressed, an injury accident caused by contact of a human body and the spiral blade is effectively avoided while splashing of the soil is effectively reduced, safety performance of the device is greatly improved, and normal operation of the device is not hindered; and uninterrupted cooling is performed on the spiral blade through a wind energy component, damage caused by high temperature of the spiral blade is avoided, and safety and service life of the device are further improved.

The invention discloses a pit digging device for peach tree planting. A lifting plate moves up and down along a supporting plate under the action of a lifting motor, and the lifting plate drives a driving mechanism on the lifting plate, a drill rod connected with the driving mechanism and a spiral blade arranged on the drill rod to move up and down while moving up and down; the drill rod drives the spiral blade to rotate to dig holes, dug soil is driven to the upper portion under the action of the spiral blade and discharged from a gap between the front and back portions of the two transition plates, and therefore, when the hole digging device digs holes, the soil in the holes can be cleared away in time; and a feeding box is filled with fertilizer and water, the fertilizer and the water can enter the area between a spiral outer cylinder and a spiral inner cylinder from the pipeline after the pit is dug, and are injected into the pit from the opening in the bottom, and growth of the peach trees is promoted. The pit digging device is high in digging speed, can improve peach tree planting efficiency, and solves the problems that traditional manual digging is low in working efficiency, wastes manpower and material resources and increases labor intensity.
