Description

Manual lifting type ground drill capable of automatically fixing working part

Technical Field

The utility model relates to a manual over-and-under type ground auger of ability automatic fixed work portion.

Background

The ground auger generally has two types of manual lifting type and vehicle-mounted type. The manual lifting ground auger is convenient to move due to small occupied space, and is widely used in work of afforestation, hole digging and fertilization in orchards and the like in mountainous regions and hilly regions. The manual lifting ground auger not only relieves people from heavy physical labor, but also improves the working efficiency.

CN 205047153U discloses a manual over-and-under type ground auger, it mainly comprises frame, guide rail, slider, rig work portion and is used for parts such as the crank and the afterburning elevating gear of rig work portion of taking off and land, and this ground auger is more laborsaving, efficiency is higher than ordinary hand-held type ground auger. However, such ground drills need to frequently lift and fix the working portion during working or maintenance, and need to be operated and lifted by one hand during fixing the working portion, so that the ground drills are not beneficial to coordination work, the working efficiency is affected, and the labor intensity is high.

Disclosure of Invention

The utility model aims at the above-mentioned defect, provide a manual over-and-under type ground auger of ability automatic fixed work portion.

The above purpose is realized by the following technical scheme:

the utility model provides a manual over-and-under type ground auger of ability automatic fixed work portion, includes the frame, be equipped with two vertical guide rails in the frame, be equipped with the slider on the guide rail, slider and rig work portion fixed connection, the top of frame is equipped with crank and the afterburning elevating gear who is used for the slider of taking off and land, the bottom of frame is equipped with preceding foot, be equipped with the fixed plate on the slider, be equipped with locating hole and swash plate on the fixed plate, the top of frame is equipped with the spring bolt with locating hole matched with.

The inclined plate inclines to the top end of the spring bolt, and the vertical inclination angle is 30 degrees.

The spring bolt consists of a sleeve, a bolt rod, a bolt cap and a spring.

The utility model discloses increased the automatic fixing device of work portion on current manual over-and-under type ground auger basis, after promoting work portion, utilize the device can be fixed with the automatic screens of work portion to increase the continuity and the harmony of operation, improved work efficiency, reduced intensity of labour simultaneously.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings.

A manual lifting ground drill is shown in a basic structure of the manual lifting ground drill in a figure 1, the manual lifting ground drill comprises a frame 1, two vertical guide rails 2 are arranged on the frame 1, sliding blocks 3 are arranged on the guide rails 2, the sliding blocks 3 are installed on the two guide rails 2 through sleeves at two ends, the sliding blocks 3 are fixedly connected with a drill working part 4, a crank 5 and a force application lifting device 6 which are used for lifting the sliding blocks 3 are arranged at the top of the frame 1, front feet 7 are arranged at the bottom of the frame 1, and the drill working part 4 sequentially comprises a power device, a gearbox and a spiral drill bit from top to bottom. The structure is a basic structure of a manual lifting ground auger, and the working mode and the principle of the structure can be referred to the published report of CN 205047153U.

When the drill is used, the height of the sliding block 3 is required to be adjusted through the crank 5 and the stress application lifting device 6, so that the drilling ground depth of the working part 4 of the drill is controlled, the working part 4 of the drill is required to be lifted by hands when the drilling ground is finished or the maintenance is carried out, and the working part 4 of the drill is required to be lifted by hands because of no fixing device on the working part 4 of the drill, so that the coordinated operation is not facilitated, the working efficiency is influenced, and the labor intensity is increased.

Therefore, an automatic fixing device is added on the sliding block 3, the device is composed of a fixing plate 8 and a spring bolt 10, the structure of the device is shown in fig. 2 and fig. 3, the fixing plate 8 and the sliding block 3 are equal in width and welded on the sliding block 3, the fixing plate 8 is provided with a positioning hole 9 and an inclined plate 11, the inclined plate 11 is located above the sliding block 3 and is integrally formed with the fixing plate 8, the spring bolt 10 is welded on the top of the rack 1, the spring bolt 10 is located right above the positioning hole 9 and is matched with the positioning hole 9, the inclined plate 11 inclines towards the top end of the spring bolt 10, and the inclination angle (vertical angle) is 30 degrees. The spring bolt 10 is composed of a sleeve 14, a bolt rod 12, a bolt cap 15 and a spring 13, and the specific structure of the spring bolt is shown in fig. 4.

After the ground drilling is finished, the working part 4 of the drilling machine is lifted by hand, the sliding block 3 moves upwards along the guide rail 2, the inclined plate 11 firstly contacts the spring bolt 10 and pushes the bolt rod 12 into the sleeve 14, after the positioning hole 9 moves upwards to the horizontal position of the spring bolt 10, the bolt rod 12 is ejected out of the sleeve 14 under the action of the spring 13 and is inserted into the positioning hole 9, the sliding block 3 is fixed at the moment, and the hand is released from the working part 4 of the drilling machine to prepare for next ground drilling operation or maintenance work. Before next earth drilling operation is carried out, the bolt cap 15 is pulled to enable the bolt rod 12 to move out of the positioning hole 9, then the height of the sliding block 3 is adjusted through the crank 5 and the stress application lifting device 6, and the working part 4 of the drilling machine can be started to carry out earth drilling operation.
