Description

A handheld digging structure Technical Field

[0001] The utility model relates to the field of pit digging devices, in particular to a handheld pit digging structure. Background Art

[0002] A pit digger is a special machine for afforestation and fertilization in mountainous, hilly and gully areas. It frees people from heavy physical labor and is widely used in afforestation, fruit orchards, fences, and fertilizing fruit trees in autumn. There are many types of pit diggers. Large pit diggers use tractors and excavators as power sources and are equipped with hydraulic systems to dig soil pits. The equipment is generally composed of three parts: a power system (tractor or excavator), a hydraulic system, and a mechanical drilling and digging system. The pit digger can be roughly divided into three categories: a portable pit digger, a front-mounted pit digger, and a rear-mounted pit digger. The front-mounted The handheld excavator is powerful and can complete a pit with a diameter of 50 cm and a depth of 2 meters in about 1 minute. Its efficiency is more than 100 times that of traditional manual digging methods and 5-7 times that of rear-mounted excavating equipment. Therefore, it can be widely used in power and telecommunications projects, municipal projects, greening and tree planting projects, construction projects, solar photovoltaic power generation projects, etc. However, the equipment is large in size and is not suitable for operations in smaller spaces. When digging small holes, a handheld excavator is used. When using a handheld excavator, the excavator can be operated by holding the handle, which is convenient for field operations.

[0003] However, the current excavator has some shortcomings. When the excavator is not in use, the staff is required to move the excavator to the road surface. However, since the excavator has a certain weight, it takes not only a lot of time but also more physical effort to move the excavator to the road surface.

When the digging machine is moved, the digging machine is tilted and the pulley is used to drag the digging machine to move. This can effectively save physical effort and can quickly move the digging machine to the designated position. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] As shown in Figures 1-4, a handheld digging structure includes a starter 1, a drill rod 4, a support plate 2 and a handle 3. The support plate 2 is fixedly installed on the lower surface of the starter 1, the drill rod 4 is fixedly installed on the output end of the starter 1, the handles 3 are fixedly installed on both side surfaces of the support plate 2, and a U-shaped rod 5 is fixedly installed on the side surface of the handle 3 on one side of the support plate 2. A movable frame 7 is movably installed on the lower end of the U-shaped rod 5, and locking blocks 6 are movably embedded in the lower surfaces of both sides of the U-shaped rod 5.

[0024] The U-shaped rod 5 has two inner surfaces and a connection block 501 fixedly installed at the upper end. The lower surface of the U-shaped rod 5 is provided with an embedding groove 502 near both sides. The U-shaped rod 5 has an extrusion groove 503 inside both sides and above the embedding groove 502. A spring 504 is provided inside the extrusion groove 503. The rear surface of the U-shaped rod 5 is provided with a connection shaft 505 fixedly installed on both sides of the lower end. The surface of the connection shaft 505 is provided with a sleeve groove. The spring 504 has a downward thrust on the stop block 602. The upper surface of the locking block 6 is fixedly installed with a guide rod 601. The upper end of the guide rod 601 passes through the embedding groove 502 and extends into the extrusion groove 503. The upper end surface of the guide rod 601 is fixedly installed. There is a stop block 602, and a push-pull block 603 is fixedly installed on the front surface of the locking block 6. After the locking block 6 is embedded in the locking groove 705, the mobile frame 7 can maintain the unchanged state after the flip. The mobile frame 7 is composed of a U-shaped sleeve 701, an extension rod 702, a fastener 704, a sleeve 706, a pulley 703, a support block 708 and a connecting plate 709. The U-shaped rod 5 is fixed to the handle 3 through the connecting block 501. The lower surface of the U-shaped sleeve 701 is fixedly installed with sleeves 706 on both sides of the rear end. The sleeves 706 are sleeved in the sleeve groove. The mobile frame 7 is movably connected to the U-shaped rod 5 through the sleeve 706. There is a certain distance between the sleeve 706 and the sleeve groove of the connecting shaft 505. The friction force can keep the mobile frame in a vertical state after being folded; an extension rod 702 is movably embedded in the interior of the U-shaped sleeve 701, and a connecting plate 709 is fixedly installed between the extension rods 702 and at the upper end; the upper end surface of the extension rod 702 and fixedly installed with support blocks 708 on both sides, and a pulley 703 is movably installed between the support blocks 708; the front surface of the extension rod 702 and the upper and lower ends thereof are provided with threaded holes 707, and the lower surface of the U-shaped sleeve 701 and the front of the shaft sleeve 706 are provided with a locking groove 705; the rear surface of the U-shaped sleeve 701 and the upper ends thereof are embedded with fasteners 704, and the rear end of the fasteners 704 is embedded in the threaded holes The U-shaped sleeve 701 is provided with a slide groove 710 on both sides below, and the rear surface of the U-shaped rod 5 is provided with a slide groove 701 on both sides below. The slide groove 710 is connected with the locking groove 705. The sum of the lengths of the U-shaped rod 5, the U-shaped sleeve 701 and the extension rod 702 is greater than the length of the drill rod 4. The upper end of the spring 504 is fixed to the inner upper surface of the extrusion groove 503, and the lower end of the spring 504 is fixed to the stop block 602. The locking block 6 is embedded in the embedding groove 502, and the push-pull block 603 is embedded in the slide groove 710. The upper end of the drill rod 4 passes through the support plate 2 and is fixed to the output end of the starter 1. The push-pull block 603 can be used to conveniently move the locking block 6.

[0025] It should be noted that the present invention is a handheld digging structure. When the digging machine is not in use, the mobile frame 7 is flipped over. During the flipping process of the mobile frame 7, the locking block 6 is squeezed into the embedding groove 502 of the U-shaped frame 5. When the mobile frame 7 is flipped over to a certain angle, the external force squeezing the locking block 6 can be released. At this time, the locking block 6 will extend out of the embedding groove 502 under the pushing action of the spring 504 until the locking block 6 is embedded in the locking groove 705 of the mobile frame 7. In this way, the mobile frame 7 can always be in a straight line with the U-shaped frame 5. Then, the fastener 704 is removed and the extension frame 702 is pulled out from the sleeve 701 to the maximum length. Finally, the rear end of the fastener 704 is embedded in another threaded hole 707 of the extension frame 702, so that the extension frame 702 can be fixed. When moving the digging machine, the digging machine is tilted and the pulley 703 is used to drag the digging machine to move. This can effectively save physical effort and can quickly move the digging machine to the designated position. When the digging machine is used normally, the mobile frame 7 is flipped and folded upward so that the mobile frame 7 is in contact with the U-shaped frame 5. Since there is a certain friction between the shaft sleeve 706 and the sleeve groove of the connecting shaft 505, the mobile frame 7 can be kept in contact with the U-shaped frame 5 when the digging machine is used.
