[0036] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 7As shown, the silo fixing device provided by the embodiment of the present invention includes a base 100. A first support seat 210 and a second support seat 220 are sequentially arranged on the base 100 along the width direction. The base 100 has a slide rail 310 extending along the width direction. The first support seat 210 is fixedly connected to the slide rail 310, and the second support seat 220 is slidably connected to the slide rail 310. The number of slide rails 310 can be two, and the two slide rails 310 are spaced apart along the length direction. The second support seat 220 is connected to a first driving mechanism, and the first driving mechanism is used to drive the second support seat 220 to move toward or away from the first support seat 210 in the width direction, thereby adjusting the distance between the first support seat 210 and the second support seat 220 and using silos of different widths.

[0038] The top surface of the first support seat 210 has a first stop plate 211 extending along the length direction, and the top surface of the second support seat 220 has a second stop plate 221 extending along the length direction. The first stop plate 211 and the second stop plate 221 are used to clamp on the left and right side walls of the silo to fix the silo in the width direction to prevent the silo from shaking.

[0039] The tail of each of the first support seat 210 and the second support seat 220 is provided with a positioning plate 230, and the positioning plate 230 is an integral structure with the first support seat 210 and the second support seat 220. The first support seat 210 is provided with a limit plate 240 that slides along the length direction. The limit plate 240 extends along the width direction and blocks the front face of the silo. The limit plate 240 is connected to a second driving mechanism, which is used to drive the limit plate 240 to move toward or away from the positioning plate 230, thereby adjusting the distance between the positioning plate 230 and the limit plate 240, and thus adapting to silos of different lengths. The limit plate 240 and the positioning plate 230 are used to clamp on the front and rear sides of the silo.

[0040] After the silo is replaced, the structure of the silo clamping device can be directly adjusted to match the new silo size without replacing the fixing device. Specifically, the first driving mechanism is used to move the second support seat 220 so that the distance between the first support seat 210 and the second support seat 220 matches the width of the silo. The silo is placed on the top surface of the first support seat 210 and the second support seat 220. The first stop plate 211 and the second stop plate 221 can stop on the left and right side surfaces of the silo to prevent the silo from shaking in the left and right directions. ; In the length direction, the rear end of the silo can be abutted against the positioning plate 230, and then the limiting plate 240 is driven by the second driving mechanism to be pressed against the front end of the silo, and the front and rear ends of the silo are clamped and fixed by using the positioning plate 230 and the limiting plate 240. The silo is fixed by clamping and limiting the silo in four directions of front, back, left and right. By adjusting the distance between the first support seat 210 and the second support seat 220, as well as the distance between the limiting plate 240 and the positioning plate 230, the device can be adapted to silos of different sizes, avoiding the need to replace the silo.

[0041] The first driving mechanism includes a first slide 410, a first screw rod 420 and a first knob 430. The first slide 410 is fixedly connected to the second support seat 220. The first screw rod 420 passes through the first support seat 210. The head end of the first screw rod 420 is connected to the first slide 410, and the tail end of the first screw rod 420 is connected to the first knob 430. The user can drive the first screw rod 420 to rotate by rotating the first knob 430, thereby driving the first slide 410 to move along the width direction.

[0042] The first screw rod 420 and the first support seat 210 are relatively stationary in the axial direction. A limit pin 440 can be set inside the first support seat 210, and a circle of annular grooves can be set on the circumferential side wall of the first screw rod 420. When the first screw rod 420 rotates, the limit pin 440 is always in the annular groove.

[0043] The first knob 430 includes an axially arranged mounting hole 431, and the tail end of the first screw rod 420 is inserted into the mounting hole 431. The first screw rod 420 and the first knob 430 are relatively stationary in the circumferential direction, but can move relative to each other in the axial direction. In other words, the first knob 430 can drive the first screw rod 420 to rotate, and the first knob 430 can be pushed or pulled in the width direction. The tail end of the first screw rod 420 has a non-circular section connected to the mounting hole 431. The cross-section of this section can be polygonal, and the cross-sectional shape of the mounting hole 431 corresponds to it, thereby achieving the effect of relative fixity in the circumferential direction and relative sliding in the axial direction.

[0044] The first knob 430 has a first annular tooth 433 on the side facing the first support seat 210, and the side wall of the first support seat 210 has a corresponding second annular tooth 212. The first knob 430 can be used to move axially in a direction away from the first support seat 210 to separate the first annular tooth 433 and the second annular tooth 212. The first knob 430 is used to adjust the position of the second support seat 220. When the adjustment is completed, it needs to be locked and the first knob 430 is pushed in the direction of the first support seat 210. The first annular tooth 433 is engaged with the second annular tooth 212, and the second annular tooth 212 prevents the first knob 430 from rotating. The first knob 430 is stationary relative to the first support seat 210, so that the first knob 430 is locked to prevent the distance between the first support seat 210 and the second support seat 220 from changing.

[0045] The first drive mechanism also includes a positioning rod 450 and a return spring 460. One end of the positioning rod 450 is connected to the tail end of the first screw rod 420, and the length of the positioning rod 450 is aligned with the length of the first screw rod 420. The other end of the positioning rod 450 has a cap having a larger diameter than the positioning rod 450. The first knob 430 is provided with a receiving hole 432 that mates with the mounting hole 431 and has a larger diameter than the mounting hole 431. The receiving hole 432 is further away from the first support seat 210 than the mounting hole 431. A stepped surface is formed at the transition between the mounting hole 431 and the receiving hole 432. The return spring 460 and the cap are both located in the receiving hole 432. One end of the return spring 460 abuts the stepped surface, and the other end abuts the cap. The return spring 460 is used to cause the first knob 430 to move toward the first support seat 210. When the first knob 430 is pulled away from the first support seat 210, the step surface will squeeze the return spring 460, and the first annular tooth 433 and the second annular tooth 212 will separate; when the first knob 430 is released, the first knob 430 moves toward the first support seat 210 driven by the return spring 460, and the first annular tooth 433 and the second annular tooth 212 will engage with each other.

[0046] A tensioning spring 500 is connected between the first support seat 210 and the second support seat 220. There can be two tensioning springs 500. Driven by the tensioning spring 500, the thread inside the first slide 410 can always be in contact with the thread on the first screw rod 420, eliminating the thread gap and avoiding errors caused by repeated movement of the first slide 410.

[0047] The second stop plate is provided with an escape hole on the side facing the first stop plate, and a pressing plate 610 is provided in the escape hole. A third driving mechanism is connected to the pressing plate 610, and the third driving mechanism is used to drive the pressing plate 610 to move toward or away from the first stop plate 211, so that the pressing plate 610 and the first stop plate 211 clamp the left and right side walls of the silo. The third driving mechanism can be a cylinder 620, and the top surface of the first support seat 210 or the second support seat 220 has a groove, and a sensor 630 is provided in the groove. After the silo is placed on the first support seat 210 and the second support seat 220, the silo blocks the sensor 630, which can be a laser displacement sensor 630. When the sensor 630 is triggered, the third driving mechanism immediately drives the pressing plate 610 to extend from the second stop plate, thereby pressing against the side wall of the silo, achieving an automatic pressing effect.

[0048] When the cam 720 is in the closed position, the locking cam 720 is in the closed position, and the locking cam 720 is in the closed position, so that the locking cam 720 can be locked.

[0049] The silo fixing device also includes a lifting mechanism, which is connected to the base 100 and is used to adjust the vertical position of the base 100. Specifically, the lifting mechanism may include a second screw rod 810, a second slide 820, a driving pulley 830, a driven pulley 840, a transmission belt 850, and a motor 860. The driving pulley 830 is connected to the rotating shaft of the motor 860, the driven pulley 840 is connected to the second screw rod 810, and the transmission belt 850 is wound around the driving pulley 830 and the driven pulley 840. The second slide 820 is connected to the second screw rod 810, and the second screw rod 810 is relatively stationary in the axial direction. The second screw rod 810 is used to drive the second slide 820 to move up and down. The motor 860 is arranged next to the second screw rod 810 and is driven by the driving pulley 830, the driven pulley 840, and the transmission belt 850, which can save space in the vertical direction.
