[0002] In the production process of feed additives, warehouse top feeding is a key process in the raw material conveying link. Usually, ton bags loaded with raw materials such as compound vitamins and mineral premixes are transferred to the warehouse top feeding hopper through the feeding equipment.

[0003] In the traditional feeding process, there is a lack of effective sealing structure between the ton bag and the feeding hopper. The dust generated when the raw materials fall is easy to escape into the production environment, which not only harms the health of the operators.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0045] Embodiment: refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 10The application relates to a warehouse top feeding vehicle for feed additive production, which comprises a feeding vehicle 1, a feeding hopper 101 mounted on the feeding vehicle 1, a lifting platform 203 slidably connected to the feeding hopper 101, a bellows 202 mounted at the bottom of the lifting platform 203, one end of the bellows 202 being fixedly connected to the feeding vehicle 1, the bellows 202 being used for sealing the space between the lifting platform 203 and the feeding hopper 101, a mounting frame 3 located in the lifting platform 203, the mounting frame 3 being provided with an empty opening used for placing a ton bag, four groups of corner air bags 401 mounted on the corners of the empty opening in the mounting frame 3, four groups of side air bags 402 mounted on the sides of the empty opening in the mounting frame 3, a plurality of air pumps 7 mounted on the mounting frame 3, the air outlet end of each air pump 7 being connected with an air outlet pipe provided with an electromagnetic valve, the air outlet pipe being connected with the corner air bags 401 and the side air bags 402, and a clamping jaw assembly mounted below the corner air bags 401 and used for clamping the corners of the ton bag so that the ton bag can keep a square shape. The corner air bags 401 and the side air bags 402 can be inflated by the air pumps 7, so that the side of the ton bag located in the empty opening can be wrapped, and meanwhile the ton bag can be clamped by the clamping jaw assembly so that the ton bag can keep a square shape and the corners and the sides of the ton bag can be tightly attached to the corner air bags 401 and the side air bags 402.

[0046] When the device is used, a zippered ton bag (the ton bag is square-shaped and the corners match the empty opening corners of the mounting frame) filled with feed additive raw materials (such as compound vitamins and mineral premixes) is lifted by a travelling crane or a forklift, the height is adjusted to about 20-50 cm above the feeding hopper 101, and the center of gravity of the ton bag is aligned with the center of the feeding hopper 101.

[0047] Then the lifting platform 203 slides upwards along the outer wall of the feeding hopper 101 until the top of the empty opening of the mounting frame 3 in the lifting platform 203 contacts the bottom of the ton bag (at this time, the ton bag is still supported by the lifting device, and the mounting frame only plays a supporting and guiding role), at this time, the bellows 202 is stretched, and since the two ends of the bellows 202 are fixedly connected to the bottom of the lifting platform 203 and the feeding vehicle 1 respectively, the bellows 202 is tightly attached to form a closed space, thereby avoiding dust flying.

[0048] Then the position of the ton bag is slightly adjusted by manually pulling the rope, so that the four corners of the ton bag correspond to the four corners of the empty opening of the mounting frame 3, and the subsequent air bags and the clamping jaw assembly can accurately act on the side of the ton bag. It should be noted that at this time, the zip of the ton bag is in a closed state, the pulling rope is located outside the ton bag and is held by the worker, and then the corners of the ton bag are clamped and fixed by the clamping jaw assembly. At this time, the ton bag is completely fixed in the empty opening of the mounting frame 3 and keeps a square shape.

[0049] Then start the air pump 7, open the corresponding electromagnetic valve of the corner air bag 401 and the side air bag 402, slowly inflate the air bag, at this time the air bag slightly expands, contacts the side of the ton bag but does not completely fit, and leaves the operation space of the ton bag zipper pull, then pull the zipper pull at the bottom of the ton bag, at this time the pull rope passes out of the gap between the side air bag 402 and the ton bag, slowly pulls it apart along the zipper direction, because the air bag is only pre-inflated, there is no obstruction during the pulling of the pull rope, and the closed space formed by the corrugated pipe 202 has preliminarily blocked the dust overflow, at this time the gap between the air bag and the ton bag can be seen by the naked eye, and the pull rope is completely pulled out, the zipper is completely opened, and the subsequent air bag is completely inflated, tightly wrapping the four corners and four sides of the ton bag, seamlessly fitting the surface of the ton bag, and filling the gap after the pull rope is pulled out, forming a ring-shaped sealing band, blocking the dust dispersion path.

[0050] It should be noted that at this time, a small amount of dust may be discharged through the gap between the air bag and the ton bag which is not completely inflated.

[0051] After the ton bag zipper is opened, the raw materials fall from the bottom opening under the action of gravity, enter the feeding hopper 101 through the empty opening of the mounting frame 3 and the internal space of the lifting platform 203, and the dust generated during the falling of the raw materials is limited in the closed space and cannot escape to the outside due to the wrapping effect of the corner air bag 401 and the side air bag 402.

[0052] Further, as shown in Figure 6 The clamping jaw assembly includes a telescopic rod two 502, two groups of connecting rods one 503, two groups of connecting rods two 504, and two groups of clamping plates 505. The telescopic rod two 502 is located on the corners of the empty opening in the mounting frame 3, and a mounting bracket is installed on the telescopic rod two 502. One end of the connecting rod one 503 is rotatably connected to the mounting bracket, the connecting rod two 504 is L-shaped, the bending part of the connecting rod two 504 is rotatably connected to the telescopic end of the telescopic rod two 502, the other end of the connecting rod one 503 is rotatably connected to one end of the connecting rod two 504, and the other end of the connecting rod two 504 is fixedly connected to the clamping plate 505. By shortening the telescopic end of the telescopic rod two 502, the two groups of clamping plates 505 can be synchronously approached, thereby clamping and fixing the corners of the ton bag. A telescopic rod one 501 is fixedly connected to the corners of the empty opening in the mounting frame 3, and the telescopic rod two 502 is installed on the telescopic end of the telescopic rod one 501. The telescopic rod one 501 can make the clamping plate 505 approach and move away from the side of the ton bag, and the clamping surface of the clamping plate 505 is provided with anti-skid lines.

[0053] When the corner of the ton bag is clamped by the clamp jaw assembly, the telescopic rod 1 501 at the corner of the mounting frame 3 is started to make its telescopic end extend, and then drive the telescopic rod 2 502 on the mounting frame to move, and then the telescopic end of the telescopic rod 2 502 is shortened, and through the transmission of the connecting rod 1 503 and the connecting rod 2 504, the two groups of L-shaped connecting rod 2 504 drive the clamping plate 505 to rotate synchronously to the middle, until the anti-skid lines of the clamping plate 505 are in close contact with the corner of the ton bag, at this time the ton bag is completely fixed in the empty opening of the mounting frame 3, and keeps the square state.

[0054] Further, as shown in Figure 8 、 Figure 9 , a plurality of groups of inflatable air bags 6 are annularly installed in the lifting platform 203, the side wall of the mounting frame 3 abuts against the inflatable air bag 6, a plurality of groups of sub-pipes with electromagnetic valves are connected to the gas outlet pipe, and the plurality of groups of sub-pipes are connected to the plurality of groups of inflatable air bags 6, and the gas outlet pipe and the sub-pipe are both provided with a pressure relief electromagnetic valve for discharging the gas inside the air bag. The bottom of the lifting platform 203 is fixedly connected with a supporting plate, which is used to support the mounting frame 3, so as to facilitate the sliding of the mounting frame 3 in the lifting platform 203.

[0055] In order to avoid the accumulation of raw materials in the ton bag, especially at the corner, at this time the inflatable air bag 6 is started, the corresponding sub-pipe electromagnetic valve of the air bag at the first position in the clockwise direction of the annularly distributed inflatable air bag 6 is opened, and the pressure relief electromagnetic valve of the air bag at the opposite position is also opened. At this time, the air bag at this position is inflated and expanded, pushing the mounting frame 3 to tilt in the opposite direction, while the air bag at the opposite position is deflated and shrunk, cooperating with the movement of the mounting frame 3, and the air bags are switched in sequence according to the clockwise sequence. Each air bag inflates for 2 seconds and deflates for 2 seconds, so that the mounting frame 3 slowly shakes in the clockwise direction in the lifting platform 203, and the inertia is used to make the raw materials in the ton bag fall evenly, improving the falling speed.

[0056] Another embodiment, as shown in Figure 9 , a plurality of groups of chambers 301 are arranged in the mounting frame 3, and a gas pump 7 is arranged in the chamber 301. A cover plate 302 is detachably arranged on the chamber 301.

[0057] When the device is assembled, the gas pump 7 is installed in the chamber 301, and the chamber 301 plays a role in fixing and protecting the gas pump 7. During the working process of the gas pump 7, the chamber 301 can reduce the interference of external factors on the gas pump 7, such as the adhesion of raw material dust and the impact of device shaking on the gas pump 7, to ensure the stable operation of the gas pump 7. It should be noted that the gas inlet end of the gas pump is in communication with the outside world, which is used to suck clean gas.

[0058] A plurality of groups of lifting telescopic cylinders 201 are fixedly connected to the feeding vehicle 1, and the telescopic ends of the lifting telescopic cylinders 201 are fixedly connected to the lifting platform 203.

[0059] Feed additive production with warehouse top feeding method, for feed additive production with warehouse top feeding car, mainly includes the following operation steps:

[0060] Step one, through the lifting device zippered ton bag is lifted, and moves to the feeding hopper 101 above;

[0061] Step two, through the lifting telescopic cylinder 201, the lifting platform 203 is moved to the ton bag bottom, the bellows 202 is stretched to form a preliminary closed space;

[0062] Step three, manually rotate the ton bag, align the corners with the corners of the air port, and stabilize the alignment to stop shaking;

[0063] Step four, through the jaw assembly, the corners of the ton bag are clamped and fixed;

[0064] Step five, start the air pump 7, inflate the corner air bag 401 and the side air bag 402, then pull the zipper at the bottom of the ton bag through the pull rope, so that the feed additive raw materials in the ton bag are discharged from the bottom into the feeding hopper 101 below;

[0065] Step six, by opening the electromagnetic valve in the auxiliary pipe, the ring-shaped installed expansion air bag 6 is inflated clockwise one by one, and the expansion air bag 6 located on the opposite side is reduced synchronously under the action of the pressure relief electromagnetic valve, so that the installation frame 3 constantly shakes in the lifting platform 203;

[0066] Step seven, when the ton bag is emptied, open the pressure relief electromagnetic valve, reset the jaw assembly and the lifting platform 203, and move the ton bag out.
