[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 5 The utility model provides a pneumatic planting hole-making device, comprising a support frame, a cylinder fixedly connected to the middle part of the support frame; a pneumatic shaft is slidably connected to the output end of the cylinder; a connecting plate is fixedly connected to the lower end of the pneumatic shaft; a motor is fixedly connected to the bottom of the connecting plate; a rotating shaft is fixedly connected to the output end of the motor; a mounting block is fixedly connected to the lower end of the rotating shaft; a drill bit is installed inside the mounting block; a mounting groove is provided at a position corresponding to the drill bit below the mounting block, and the drill bit is slidably connected in the mounting groove; a mounting assembly is provided at a position corresponding to the drill bit on the outside of the mounting block, and the mounting assembly includes a bidirectional screw rod, a slide plate and an insertion rod; the slide plate is slidably connected to the outside of the bidirectional screw rod; the insertion rod is fixedly connected to a side of the slide plate close to the mounting block, and the insertion rod is inserted into the mounting block and the drill bit.

[0026] During operation, in the current prior art, although the drill bit can be fixed by the cooperation of the limit block and the limit spring, the drill bit will vibrate when the drilling rig is used. At the same time, the limit spring is an elastic part. During the vibration of the drill bit, the limit spring may fall off from the drill bit, causing the drill bit to lose its fixation and thus unable to work normally. The device rotates through a two-way screw rod, and the rotation of the two-way screw rod drives the slide plate to move outside the two-way screw rod and move away from each other. During the process of the slide plate moving away from each other, the insertion rod will be driven to move and disengage from the slot. At this time, the drill bit loses its fixation, and the drill bit can be removed, and a new drill bit can be taken and inserted into the installation slot. The two-way screw rod is reversed and the insertion rod is inserted into the slot again, thereby fixing the new drill bit.

[0027] Further, such as Figure 1-Figure 4 As shown, the mounting assembly also includes L-shaped plates symmetrically arranged and fixedly connected to both sides of the mounting block, and a bidirectional screw is rotatably connected between the two L-shaped plates; one end of the bidirectional screw passes through one of the L-shaped plates; one end of the bidirectional screw passing through one of the L-shaped plates is fixedly connected to a worm gear; a worm is meshed on the outer side of the worm gear; a rotating ring is fixedly connected to the upper end of the worm; slots are respectively provided at the positions of the mounting block and the drill bit corresponding to the insertion rod, and the insertion rod is inserted into the slots.

[0028] During operation, when the drill bit is damaged and needs to be replaced, the user first rotates the rotating ring, which drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate, and the rotation of the worm wheel drives the two-way lead screw to rotate, and the rotation of the two-way lead screw drives the slide plate to move on the outside of the two-way lead screw and move away from each other. In the process of the slide plates moving away from each other, the plug rod will drive to move and disengage from the slot. At this time, the drill bit loses its fixation, and the drill bit can be removed, a new drill bit can be taken, and the new drill bit can be inserted into the installation slot. The user reverses the rotating ring, and under the action of the two-way lead screw, the plug rod is inserted into the slot again, thereby fixing the new drill bit. The worm wheel and the worm have a self-locking function, and the vibration of the drill bit will not cause the worm wheel and the worm to rotate, thereby preventing the drill bit from falling off and affecting normal work.

[0029] Further, such as Figure 1-Figure 4 As shown, a symmetrically arranged limiting rod is fixedly connected to the position of the slide plate on the outer side of the mounting block; the other end of the limiting rod is fixedly connected to the L-shaped plate, and the slide plate is slidably connected to the outer side of the limiting rod.

[0030] During operation, the slide plate is slidably connected to the outer side of the limit rod through the installation block and the limit rod fixed on the L-shaped plate. The position of the slide plate can be limited in cooperation with the bidirectional screw rod to prevent the slide plate from deflecting.

[0031] Further, such as Figure 5 As shown, a symmetrically arranged positioning rod is fixedly connected to the outer side above the drill bit; a symmetrically arranged positioning groove is opened at the position of the mounting block corresponding to the positioning rod, and the positioning rod is slidably connected in the positioning groove.

[0032] During operation, the positioning rod fixed on the outer side above the drill bit and the positioning groove opened on the mounting block can be used to make the positioning rod slidably connected in the positioning groove, so as to limit the position of the drill bit, thereby making the drill bit more stable and more convenient to install.

[0033] Further, such as Figure 5 As shown, a first arc surface is provided on the upper end of the drill bit; a second arc surface is provided at a position corresponding to the mounting groove below the mounting block, and the first arc surface and the second arc surface are used in conjunction with each other.

[0034] During operation, through the No. 1 arc surface opened on the upper end of the drill bit and the No. 2 arc surface opened on the mounting block, when the drill bit is inserted into the mounting groove, the No. 1 arc surface will first contact the No. 2 arc surface, thereby facilitating the insertion of the drill bit.

[0035] Further, such as Figure 2 As shown, a protection box is fixedly connected to one of the L-shaped plates at a position corresponding to the worm wheel and the worm, and the worm wheel and the worm are located in the protection box.

[0036] During operation, the protection box fixed on the L-shaped plate can protect the worm wheel and the worm, and can also support the worm.

[0037] Working principle:

[0038] When the drill bit is damaged and needs to be replaced, the user first rotates the rotating ring, which drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate, and the rotation of the worm wheel drives the two-way lead screw to rotate. The rotation of the two-way lead screw drives the slide plate to move on the outside of the two-way lead screw and move away from each other. In the process of the slide plates moving away from each other, the plug rod will move and disengage from the slot. At this time, the drill bit loses its fixation, and the drill bit can be removed, a new drill bit can be taken, and the new drill bit can be inserted into the installation slot. The user reverses the rotating ring, and under the action of the two-way lead screw, the plug rod is inserted into the slot again, thereby fixing the new drill bit. The worm wheel and the worm have a self-locking function, and the vibration of the drill bit will not cause the worm wheel and the worm to rotate, thereby preventing the drill bit from falling off and affecting normal work.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
