Description

TECHNICAL FIELD

[0001] The utility model relates to a pit digging device technical field, specifically a portable pit digging device for fruit tree planting. BACKGROUND

[0002] The fruit tree planting pit digging device is a mechanical equipment for efficiently and accurately digging planting pits in the process of orchard construction and fruit tree cultivation. For example, the handheld pit digger is mainly composed of an engine, a transmission device and a drill bit and is operated by one person. The engine provides power to drive the drill bit to rotate through the transmission device. The drill bit is usually spiral-shaped and cuts into the soil during rotation to bring the soil out of the pit. This pit digger is small in size, flexible in operation and suitable for use in small-area orchards, mountains or complex terrain areas and can be operated in the case of small fruit tree plant spacing.

[0003] Chinese patent publication No. CN 208581468 U discloses a pit digger. The utility model discloses a drill rod and drive device that drives the drill rod to rotate. The drive device is rotatably arranged on the frame through a drive frame. The drill rod and the drive device are located behind the wheels. The drill rod and the drive device are located in front of the handle. A switch is arranged on the handle to control the operation of the drive device.

[0004] The above-mentioned patent provides a portable pit digging device mainly used in mountains or hilly areas. When going uphill or downhill, the pit digging device needs to be pushed. The height of the front wheel is different from the height of the operator, so the drill is easy to scratch the ground. The operator needs to hold the drill high to avoid such situations. However, this action cannot be maintained for a long time, and it is extremely inconvenient and labor-intensive to operate. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a portable pit digging device for fruit tree planting. The pit digging mechanism can be turned over when pushing, which has good controllability whether going uphill, downhill or on flat ground, greatly reduces the labor intensity of the operator and makes pushing easier.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A portable pit digging device for fruit tree planting includes a movable frame body. A pit digging assembly is installed on the movable frame body.

[0008] The pit digging assembly has two fixed sleeve plates fixed with the movable frame body, a turnover frame is arranged between the two fixed sleeve plates, convex shafts are arranged on the two sides of the turnover frame, the convex shafts are rotationally connected with the fixed sleeve plates, outer threads are formed on the outer ends of the convex shafts, and locking caps are threadedly connected with the outer threads.

[0009] A gasoline engine is fixed on the turnover frame, and a Jiaolong drill is connected with the driving part of the gasoline engine.

[0010] As a further technical scheme of the utility model, the movable frame body comprises a front fork, a walking wheel is cooperatively installed at one end of the front fork, a connecting piece is connected with the front fork through a pin shaft, and the connecting piece is further movably connected with the supporting frame through the pin shaft.

[0011] A locking sleeve is further sleeved at the connecting position of the front fork and the supporting frame.

[0012] As a further technical scheme of the utility model, the end of the supporting frame away from the locking sleeve is further integrally provided with a holding part.

[0013] As a further technical scheme of the utility model, a groove is formed at the end of the locking sleeve close to the front fork, and the groove is arranged in a J shape; and a T-shaped column for locking the groove is welded on the front fork.

[0014] As a further technical scheme of the utility model, an inner thread is formed at the end of the locking sleeve close to the front fork; and an outer thread is formed on the outer side of the end of the connecting piece.

[0015] Compared with the prior art, the utility model has the advantages that:

[0016] 1. After the Jiaolong drill is turned to a certain angle, the Jiaolong drill will not be scraped with the ground when being pushed on the ground or uphill or downhill, and the pushing is more convenient.

[0017] 2. When the pit digging assembly is in a horizontal state, the locking sleeve is slid to one side to separate the locking sleeve from the front fork; then the front fork and the supporting frame are folded under the cooperation of the connecting piece, so that the space occupation area of the whole pit digging device is reduced, and a good portable effect is achieved.

[0018] 3. After the front fork and the supporting frame are unfolded, the locking sleeve is slid to the front fork, and then the locking sleeve is rotated to be threadedly locked with the front fork; compared with the connection mode of the T-shaped column and the groove, the connection mode is more reliable and has higher stability.

[0032] Please refer to Figures 1-2 , in the utility model embodiment, a portable pit digging device for fruit tree planting, mobile frame body 1 is installed on the cooperation and has pit digging assembly 2.

[0033] By adopting the technical scheme, when digging the pit, the hand-held movable frame body 1 is pressed down at the end, so that the pit digging assembly 2 is drilled into the ground, thereby throwing the soil in the pit, and the pit digging for planting fruit trees is realized.

[0034] Embodiment two

[0035] Please refer to the attached Figures 3-4 and Figure 7 The pit digging assembly 2 has two fixed sleeve plates 21 fixed with the movable frame body 1, and a turnover frame 22 is arranged between the two fixed sleeve plates 21, the turnover frame 22 is provided with convex shafts on both sides, the convex shafts are rotationally connected with the fixed sleeve plates 21, and outer ends of the convex shafts are provided with external threads and are threadedly connected with locking caps 23.

[0036] A gasoline engine 24 is fixed on the turnover frame 22, and the driving part of the gasoline engine 24 is connected with a Jiaolong drill 25.

[0037] By adopting the technical scheme, when pushing, first, the locking cap 23 is loosened, the turnover frame 22 is turned over by 90 degrees to one side, so that the Jiaolong drill 25 is away from the ground or arranged horizontally with the ground, then the locking cap 23 is locked to keep the horizontal effect of the Jiaolong drill 25, in order to prevent the loosening of the locking cap 23, the operator can use the iron wire or rope to constrain and fix the Jiaolong drill 25 on the movable frame body 1, so as to prevent the Jiaolong drill 25 from falling by itself when pushing.

[0038] After the Jiaolong drill 25 is turned over by a certain angle, whether pushing on the flat ground or going uphill or downhill, the Jiaolong drill 25 will not be scraped with the ground, and the pushing is more convenient.

[0039] Embodiment three

[0040] Please refer to the attached Figures 5-6 and Figure 8 In the embodiment, the movable frame body 1 comprises a front fork 11, one end of the front fork 11 is cooperatively provided with a walking wheel 12, the other end is connected with a connecting plate 16 through a pin shaft, and the connecting plate 16 is further movably connected with a supporting frame 14 through a pin shaft; a locking sleeve 13 is further sleeved at the connecting position of the front fork 11 and the supporting frame 14.

[0041] Further, one end of the supporting frame 14 away from the locking sleeve 13 is further integrally provided with a holding part 15.

[0042] By adopting the technical scheme, when not in use or when the vehicle needs to be carried, the whole pit digging device can be folded;

[0043] When the pit digging assembly 2 is in a horizontal state, the locking sleeve 13 is slid to one side so that the locking sleeve 13 is separated from the front fork frame 11; then, under the cooperation of the connecting piece 16, the front fork frame 11 and the supporting frame 14 are folded, so that the space occupation area of the whole pit digging device is reduced, and a good portable effect is achieved.
