[0024] like Figures 1 to 6As shown, a feed bag feeding and clamping device described in an embodiment of the utility model comprises a feeding assembly mounting frame 1; a fixing rod 12 is fixedly connected to the bottom of the feeding assembly mounting frame 1; a connecting rod 13 is rotatably connected to the bottom end of the fixing rod 12; a motor 14 is fixedly connected to the inner side wall of the connecting rod 13; a cross shaft 15 is fixedly connected to the output end of the motor 14; an extension rod 16 is slidably connected to the middle part of the cross shaft 15; the extension rod 16 and the connecting rod 13 are threadedly matched; a first collar 17 is slidably connected to the middle part of the extension rod 16; a plurality of first push rods 18 are hingedly connected to the middle part of the first collar 17; a second collar 19 is slidably connected to the middle part of the connecting rod 13; a plurality of second push rods 110 are hingedly connected to the middle part of the second collar 19; the second push rods 110 and the first push rods 18 are arranged in corresponding numbers; the second push rods 110 and the first push rods 18 are arranged in corresponding numbers; It is hinged by an articulated shaft column 111; a screw transmission assembly 112 is installed in the middle of the feeding assembly mounting frame 1; a moving block 113 is threadedly connected to the middle of the screw of the screw transmission assembly 112; a first electric cylinder 114 is fixedly connected to the bottom of the moving block 113; the output end of the first electric cylinder 114 is arranged to face downward, and an air intake box 115 is fixedly connected to the bottom of the output end of the first electric cylinder 114; the air inlet of the air intake box 115 is opened at the bottom; an air pump 116 is fixedly connected to the top of the feeding assembly mounting frame 1; an air intake pipe 117 is fixedly connected to the air intake end of the air pump 116; the other end of the air intake pipe 117 is connected to the air intake box 115; a second electric cylinder 118 is fixedly connected to the bottom of the feeding assembly mounting frame 1; a pair of pull ropes 119 are fixedly connected to the output end of the second electric cylinder 118; the other end of the pull rope 119 is fixedly connected to the middle of the connecting rod 13;During operation, the feeding assembly mounting frame 1 is moved to the top of the stacked feed bags, and then the air inlet box 115 is driven to descend by the operation of the first electric cylinder 114, so that the air inlet box 115 contacts the upper surface near the mouth of the feed bag, and then the air pump 116 is started to extract the air inside the air inlet box 115 through the air extraction pipe 117, so that negative pressure is formed inside the air inlet box 115, so that the air inlet box 115 will suck the part above the mouth of the feed bag, and then the air inlet box 115 is driven to move by the operation of the first electric cylinder 114. The feed bag is lifted up, and the air inlet box 115 drives the upper part of the feed bag opening to rise, thereby opening the feed bag opening. After the cross shaft 15 rises to the right position, the second electric cylinder 118 is started to shrink, and then the connecting rod 13 is pulled to rotate by the pull rope 119, so that the connecting rod 13 rotates to the direction of the open bag opening of the feed bag, and then the feed bag is driven to move in the direction of the connecting rod 13 through the operation of the screw transmission assembly 112. At this time, the multiple first push rods 18 and the second push rods 110 enter the feed bag along the bag opening. The inside of the feed bag is then driven by the motor 14 to rotate the cross shaft 15, thereby driving the extension rod 16 to rotate. When the extension rod 16 rotates, it is threadedly matched with the connecting rod 13, thereby moving the extension rod 16 toward the inside of the connecting rod 13, thereby reducing the distance between the non-joined ends of the multiple first push rods 18 and the multiple second push rods 110, thereby moving the first push rod 18 and the second push rod 110 through the end of the joint of the hinged shaft column 111 in a direction away from the connecting rod 13, thereby squeezing the inside of the feed bag, so that the feed bag is opened by the multiple second push rods 110 and the first push rod 18, and then the second electric cylinder 118 is extended to make the connecting rod 13 rotate downward under its own gravity, thereby driving the feed bag to rotate downward, so that the opening of the feed bag faces upward, and then the feed bag is transported to the bottom of the feed discharge port for feed packaging. Through the above structure, the feed bag can be automatically opened when the feed is packaged, and feed bags with different bag opening sizes can be opened and clamped, which improves the application range of the device. ;

[0025] like Figures 1 to 4As shown, the air outlet end of the air pump 116 is fixedly connected with an exhaust pipe 2; the other end of the exhaust pipe 2 is connected to the connecting rod 13; a plurality of ventilation pipes 21 are opened in the middle of the cross shaft 15; an exhaust hole 22 is opened at one end of the extension rod 16 away from the connecting rod 13; during operation, in the process of putting the feed bag on the hinged joints of the plurality of first push rods 18 and the second push rod 110, the air pump 116 will continue to operate to allow the air inlet box 115 to adsorb the feed bag, and at the same time, the gas discharged by the air pump 116 will enter the interior of the connecting rod 13 through the exhaust pipe 2, and then the gas will flow through the ventilation pipe 21 and then be discharged through the exhaust hole 22, and then the air flow will spray to the bag mouth of the feed bag, thereby filling the feed bag with gas, so that the bag mouth of the feed bag can be kept open, and then it can be conveniently put on the hinged joints of the plurality of second push rods 110 and the first push rod 18. Through the above structure, the bag mouth of the feed bag can be kept open during the bagging process, which is convenient for bagging and reduces the occurrence of bagging failure.

[0026] like Figures 1 to 4 As shown, the middle part of the connecting rod 13 is threadedly connected with an adjusting ring 3; the second ring 19 is rotatably connected to the side wall of the adjusting ring 3; when working, the second ring 19 is driven to approach or move away from the first ring 17 by rotating the adjusting ring 3, so that the maximum distance between the hinges of the multiple groups of second push rods 110 and the first push rods 18 and the connecting rod 13 is increased or decreased, further enabling the device to bag and clamp feed bags with more bag opening sizes, further improving the scope of application of the device.

[0027] like Figures 1 to 4 As shown, a fixed head 4 is fixedly connected to the end of the extension rod 16; the fixed head 4 is communicated with the exhaust hole 22; a plurality of diversion ports 41 are opened in the middle of the fixed head 4; during operation, when bagging, the airflow ejected from the exhaust hole 22 will be ejected in a diffused manner through the plurality of diversion ports 41, so that when the bag opening of the feed bag passes through, the bag opening is blown open, the opening force of the bag opening is increased, and the occurrence of bagging failure is reduced.

[0028] like Figures 1 to 5 As shown, a pair of elastic ropes 5 are fixedly connected to both ends of the hinged shaft column 111; a plurality of supporting rubber plates 51 are fixedly connected to the ends of the elastic ropes 5; when working, the plurality of supporting rubber plates 51 will be attached to the hinge of the second top rod 110 and the first top rod 18 under the pulling of the elastic ropes 5, and then when the extension rod 16 moves toward the inside of the connecting rod 13, the supporting rubber plates 51 will be driven to squeeze toward the inside of the feed bag, thereby increasing the contact area between the feed bag and the device in the clamping state, thereby increasing the friction, reducing the occurrence of the feed bag falling off, and reducing the occurrence of the feed bag being broken.

[0029] like Figures 1 to 6As shown, the side wall of the air inlet box 115 is provided with a plurality of air inlet grooves 6; the plurality of air inlet grooves 6 are evenly arranged on the side wall of the air inlet box 115; during operation, when the air permeability of the material of the feed bag is poor, it is difficult for the bottom of the air inlet box 115 to inhale enough gas, which may cause the air pump 116 to be overloaded and damaged. By setting the air inlet grooves 6, external air can be inhaled into the air pump 116 through the air inlet grooves 6, thereby reducing the occurrence of overload and damage to the air pump 116.

[0030] like Figure 6 As shown, a blocking net 7 is fixedly connected to the bottom of the air inlet box 115; the blocking net 7 surrounds the air inlet at the bottom of the air inlet box 115; when working, the setting of the blocking net 7 can reduce the situation where the middle part of the feed bag is sunk into the air inlet of the air inlet box 115 due to strong suction, thereby reducing the occurrence of suction marks inside the feed bag.

[0031] During operation, the feeding assembly mounting frame 1 is moved to the top of the stacked feed bags, and then the operation of the first electric cylinder 114 drives the air inlet box 115 to descend, so that the air inlet box 115 contacts the upper surface near the mouth of the feed bag, and then the air pump 116 is started, and the air inside the air inlet box 115 is extracted through the air suction pipe 117, so that a negative pressure is formed inside the air inlet box 115, so that the air inlet box 115 will suck the upper part of the mouth of the feed bag, and then the operation of the first electric cylinder 114 drives the air inlet box 115 to rise, at this time, the air inlet box 115 will drive the upper part of the mouth of the feed bag to rise, and then the mouth of the feed bag is opened, and after the cross shaft 15 rises to the position, the second electric cylinder 118 is started to shrink, and then the pull rope 119 is used to pull the pull rope 119. The connecting rod 13 is pulled to rotate, so that the connecting rod 13 rotates to the direction of the bag opening of the feed bag, and then the feed bag is driven to move toward the direction of the connecting rod 13 through the operation of the screw transmission assembly 112. At this time, multiple first push rods 18 and second push rods 110 will enter the interior of the feed bag along the bag opening of the feed bag, and then the motor 14 is started to drive the cross shaft 15 to rotate, thereby driving the extension rod 16 to rotate. While the extension rod 16 rotates, it is threadedly engaged with the connecting rod 13, so that the extension rod 16 moves toward the inside of the connecting rod 13, thereby reducing the distance between the non-joined ends of the multiple first push rods 18 and the multiple second push rods 110, so that the first push rods 18 and the second push rods 110 are moved toward the far end through the end of the joint of the hinged shaft column 111 The feed bag is moved in the direction away from the connecting rod 13, thereby squeezing the inside of the feed bag, so that the feed bag is stretched open by the multiple second push rods 110 and the first push rod 18, and then the second electric cylinder 118 is extended to make the connecting rod 13 rotate downward under its own gravity, thereby driving the feed bag to rotate downward, so that the opening of the feed bag faces upward, and then the feed bag is transported to the bottom of the feed discharge port for feed packaging. In the process of putting the feed bag on the hinges of the multiple first push rods 18 and the second push rod 110, the air pump 116 will continue to operate to make the air inlet box 115 adsorb the feed bag, and at the same time, the gas discharged by the air pump 116 will enter the inside of the connecting rod 13 through the exhaust pipe 2, and then the gas will flow through the ventilation pipe 21 and then be discharged through the exhaust hole 22, and then the air flow The air will be sprayed toward the mouth of the feed bag, thereby filling the feed bag with gas, so that the mouth of the feed bag can be kept open, and then it can be conveniently put on the hinge of the multiple sets of second top rods 110 and the first top rod 18. By rotating the adjustment ring 3, the second ring 19 is driven to move closer to or away from the first ring 17, so that the maximum distance between the hinge of the multiple sets of second top rods 110 and the first top rod 18 and the connecting rod 13 is increased or decreased. When bagging, the air flow ejected from the exhaust hole 22 will be ejected in a diffused manner through the multiple diversion ports 41, so that when the mouth of the feed bag passes by, the mouth of the bag is blown open, and the opening force of the mouth of the bag is increased. The multiple supporting rubber plates 51 will be attached to the hinge of the second top rod 110 and the first top rod 18 under the pulling of the elastic rope 5.When the extension rod 16 moves toward the inside of the connecting rod 13, the supporting rubber plate 51 will be driven to squeeze toward the inside of the feed bag, thereby increasing the contact area between the feed bag and the device in the clamping state, thereby increasing the friction. When the air permeability of the feed bag is poor, it is difficult for the bottom of the air inlet box 115 to absorb enough air, which will cause the air pump 116 to be overloaded and damaged. By setting the air inlet groove 6, external air can be sucked into the air pump 116 through the air inlet groove 6, reducing the occurrence of overload damage to the air pump 116.
