The following describes each embodiment of the present invention in detail with reference to the drawings.

[0037] Embodiment 1

[0038] Please refer to Figures 1 to 10, the present invention preferably provides a technical solution: a quality inspection sampling device for feed additive production, including: a frame; a to-be-conveyed mechanism disposed on the frame; and two baffles 113 disposed on the frame, wherein the to-be-conveyed mechanism and the two baffles 113 form a region for the flow detection and conveyance of feed additives; the to-be-conveyed mechanism includes two driving rollers 116, a driving belt 114 driven by the two driving rollers 116, sampling inspection parts evenly distributed on the driving belt 114; and an opening and closing channel plate assembly disposed at the center of each sampling inspection part; further includes a sampling cylinder assembly disposed on one of the baffles 113, a driving bracket is installed on the sampling cylinder assembly, when the sampling cylinder assembly is placed directly below one of the sampling inspection parts, the driving bracket operates and drives the sampling inspection part to gather and contract inwards, so that the opening and closing channel plate assembly is opened, and the feed additives in this sampling inspection part fall and enter the interior of the sampling cylinder assembly.

[0039] In this embodiment, the provided to-be-conveyed mechanism and the two baffles 113 can jointly form a region for the flow detection and conveyance of feed additives. As shown in combination with Figure 1 , the setting of this region can not only efficiently complete the conveyance of feed additives, but also randomly or at equal intervals realize the sampling process of feed additives during the conveyance process. Specifically, in combination with Figure 2 , 3 , as shown in Figure 4, the driving belt 114 sleeved on the driving roller 116 is evenly provided with sampling inspection parts, an opening and closing channel plate assembly is disposed at the center of each sampling inspection part, and a sampling cylinder assembly placed in the middle of the driving belt 114 is further disposed on the baffle 113. Therefore, under the rotation of the driving belt 114, by adjusting the sampling inspection part above the sampling cylinder assembly, the equal-interval or random sampling of feed additives is realized. The driving bracket installed below the sampling cylinder assembly, when driven, on the one hand, can drive the sampling inspection part to gather and contract inwards, so that the feed additives converge towards the opening and closing channel plate assembly; on the other hand, the gathering and contraction inwards of the sampling inspection part can also drive the opening and closing channel plate assembly to open, completing the process of the feed additives falling into the interior of the sampling cylinder assembly to complete the sampling process. The present invention can convey feed additives in a pipeline manner and sample them at equal intervals or randomly by setting the to-be-conveyed mechanism, improving the practicability of the device. At the same time, the setting of the driving bracket can make the sampling inspection part gather and contract inwards, and the power of this gathering not only completes the convergence of the feed additives towards the opening and closing channel plate assembly, but also drives the opening and closing channel plate assembly to open, realizing the process of the feed additives falling and entering the interior of the sampling cylinder assembly to complete the sampling.

[0040] Further, the frame includes a frame base 111, two groups of frame bodies 112 provided at both ends of the frame base 111, two driving rollers 116 are respectively rotatably installed on the opposite surfaces of the two groups of frame bodies 112; and a driving motor 115 provided on one of the frame bodies 112, the telescopic end of the driving motor 115 passes through a through hole opened on the side wall of one of the frame bodies 112 and is fixedly connected to the corresponding driving roller 116; it further includes a speed reducer provided on the driving motor 115 for controlling the speed of the driving motor 115.

[0041] Combined with Figure 1 、 2 As shown in Figure 3, the driving motor 115 can be used as the driving structure of the driving roller 116 here. Combined with the speed reducer, the intermittent driving process of the driving roller 116 at equal intervals or randomly can be completed, and then the position adjustment process of several sampling and testing parts above the sampling cylinder assembly can be realized. The speed reducer is a mature existing technology and will not be elaborated here.

[0042] Embodiment 2

[0043] As another embodiment of the present invention, each sampling and testing part includes a flexible part 211, where the flexible part 211 is composed of a wrinkled part and a flat part; several installation grooves provided on the flat part, each installation groove is provided with a support bar 212, a groove 213 for holding feed additives is opened on the upper surface of the support bar 212, and the inner ends of several grooves 213 converge towards the center and are fixed with an elastic ring 214; and a support block 215 fixed in the middle of the elastic ring 214; it further includes a through groove 216 opened in the middle of the support block 215, and an opening and closing channel plate assembly is used to control the opening and closing of the through groove 216.

[0044] Here, the support bars 212 are preferably four, and are distributed in a cross shape as a whole. At the same time, the grooves 213 opened on them are in a converging and communicating state at the center. An elastic ring 214 is fixed in the middle of the four grooves 213. The through groove 216 opened on the support block 215 fixed in the middle of the elastic ring 214 can be above the sampling cylinder assembly. Combined with Figure 5 、 6 As shown, it is used for the dropping of feed additives. It should be noted that the opening and closing channel plate assembly is used to control the opening and closing of the through groove 216, and the flexible part 211 as a whole has elasticity and is composed of a wrinkled part and a flat part. Therefore, when the transmission bracket is running, as Figure 5 、 7 As shown, it can make the flexible part 211 and the elastic ring 214 deform by pushing the four support bars 212 to gather upward and inward, so that the feed additives placed on the sampling and testing part gather towards the through groove 216. And at this time, the power of the four support bars 212 gathering inward and upward can drive the opening and closing channel plate assembly to open, that is, the through groove 216 is opened, and the sampling cylinder assembly can realize the sampling process of feed additives.

[0045] Embodiment 3

[0046] As other embodiments of the present invention, the opening and closing channel plate assembly includes a retaining strip 217 fixed to the lower surface of each support bar 212, and each retaining strip 217 includes a straight plate at the outer end and a sector plate at the inner end. When a plurality of retaining strips 217 are brought together, the plurality of sector plates are combined into a complete circle and cover the bottom of the through groove 216 for closing the through groove 216.

[0047] In this embodiment, in combination with Figure 8 、 9 as shown, each retaining strip 217 includes a straight plate at the outer end and a sector plate at the inner end. When the four support bars 212 are driven by the transmission bracket to move upward and inward, the retaining strips 217 fixed to the bottom of each support bar 212 are flipped, and the sector plates combined into a complete circle are separated and disengaged from the through groove 216, so that the through groove 216 is opened, and vice versa to close the through groove 216.

[0048] Embodiment 4

[0049] As other embodiments of the present invention, the sampling cylinder assembly includes an L-shaped frame 311 fixed to the middle of one of the baffles 113. A support frame 312 is fixed to the horizontal section of the L-shaped frame 311, and a cylinder body 313 is provided on the support frame 312. The top of the cylinder body 313 is aligned below the through groove 216 for receiving the feed additive dropped from the through groove 216.

[0050] In combination with Figure 5 、 6 as shown, the top of the cylinder body 313 is open and aligned below the through groove 216. When a plurality of retaining strips 217 are disengaged from the through groove 216, the through groove 216 can be made to face the cylinder body 313, and the feed additive converging above the through groove 216 drops through the through groove 216 into the interior of the cylinder body 313 to complete sampling.

[0051] Furthermore, the transmission bracket includes a transmission sleeve 314 sleeved on the cylinder body 313, a first transmission rod 315 annularly fixed to the upper part of the transmission sleeve 314, and each first transmission rod 315 is rotatably installed with a third transmission rod 316 at one end away from the transmission sleeve 314 through a first pin shaft provided at its end; and a second transmission rod 318 annularly fixed to the upper part of the cylinder body 313, the second transmission rod 318 corresponds to the support bar 212 one by one, and each second transmission rod 318 is rotatably installed with a V-shaped rod 317 through a second pin shaft. Among them, one end of the V-shaped rod 317 is rotatably installed with the end of the third transmission rod 316 away from the first transmission rod 315 through a third pin shaft, and the other end thereof is placed below the corresponding support bar 212; it further includes a cam transmission assembly provided on the horizontal section of the L-shaped frame 311 for the longitudinal sliding of the transmission sleeve 314.

[0052] In combination with Figure 5 、 6As shown, a first transmission rod 315 and a second transmission rod 318 are respectively and annularly fixed on the transmission sleeve 314 and the upper part of the cylinder body 313. One end of a V-shaped rod 317 rotatably connected to each second transmission rod 318 is connected to the corresponding first transmission rod 315 through a third transmission rod 316, and the other end is placed below the corresponding support bar 212. Moreover, the transmission sleeve 314 and the cylinder body 313 are slidably installed. Therefore, when the transmission sleeve 314 longitudinally slides on the cylinder body 313 by the power provided by the cam transmission assembly, it pushes the four V-shaped rods 317 to turn upward or downward and pushes the four support bars 212 to gather upward and inward or to spread downward and outward.

[0053] Furthermore, the cam transmission assembly includes a seat body 411, a first motor 412 provided on the seat body 411, and a transmission disk 413 fixed to the output end of the first motor 412; and a transmission groove 414 opened on the side wall of the transmission disk 413, wherein the transmission groove 414 is composed of a concave section and a convex section; it also includes a first support rod 415 fixed on the L-shaped frame 311. The first support rod 415 is rotatably installed with a second support rod 416 through a rotating shaft. Among them, a transmission column 417 provided on the second support rod 416 is limited to slide inside the transmission groove 414. Installation shafts 418 are respectively rotatably installed on the opposite surfaces of the U-shaped end of the second support rod 416, and a limiting block 419 is provided on each installation shaft 418; and a limiting sleeve 420 fixed in the middle of the transmission sleeve 314, and the two limiting blocks 419 are placed on both sides of the limiting sleeve 420 and are installed with it in a limiting manner.

[0054] Combined with Figure 6 As shown, the transmission disk 413 is rotated by the first motor 412. The transmission groove 414 opened on the side wall of the transmission disk 413 is installed in a limiting manner with the transmission column 417 provided on the second support rod 416. The limiting blocks 419 rotatably installed at the U-shaped end of the second support rod 416 are also installed in a limiting manner with the limiting sleeve 420 fixed on the transmission sleeve 314. Therefore, when the transmission disk 413 rotates, when the convex end of the transmission groove 414 is connected to the transmission column 417, it pushes the transmission column 417 to swing upward, and then drives the limiting block 419 to deflect adaptively and move upward, so that the transmission sleeve 314 moves upward on the outer wall of the cylinder body 313 and pushes the V-shaped rod 317 upward. On the contrary, when the concave section of the transmission groove 414 is connected to the transmission column 417, the second support rod 416 swings downward, the transmission sleeve 314 moves downward on the outer wall of the cylinder body 313, and the V-shaped rod 317 deflects downward.

[0055] Embodiment 5

[0057] Combined with Figure 6As shown in the figure and in combination with the above text, the V-shaped rod 317 deflects with the second pin shaft on the second transmission rod 318 as the axis. Specifically, taking the right V-shaped rod 317 in Figure 6 as an example, when the transmission sleeve 314 moves upward, it pushes the V-shaped rod 317 to deflect counterclockwise upward. Conversely, the V-shaped rod 317 deflects clockwise downward. During the downward deflection process, the knocking ball 612 on the knocking rod 611 can knock the L-shaped frame 311, causing the L-shaped frame 311 to vibrate and reducing the feed additive adhered to its interior.

[0058] Embodiment 6

[0059] As other embodiments of the present invention, a diverse transmission mechanism is provided on the frame base 111.

Among them, each mounting member 514 includes a block portion and a ring portion, and the block portion is fixedly connected to the transmission belt 715, and its ring portion is used to place the sample extraction cylinder 513; the sample extraction cylinder 513 includes a lower storage portion and an upper stepped portion, and the stepped portion overlaps with the ring portion where the mounting member 514 is located; a first transmission rod 315 close to the diverse transmission mechanism, on which a mounting rod 511 is fixed, and a first electromagnetic block 512 is provided at the bottom of the mounting rod 511; and mounting blocks 515 provided on the stepped portions where each sample extraction cylinder 513 is located, and a second electromagnetic block provided in the mounting block 515 is magnetically attracted to the first electromagnetic block 512; it further includes a second motor 716 provided on one of the mounting plates 713, and the output end of the second motor 716 passes through the mounting plate 713 and is fixed to the corresponding transmission wheel 714.

[0060] Combined with Figure 1 、 2As shown in Figures 3 and 4, the conveyor belt 715 is sleeved on four conveyor wheels 714, and the four conveyor wheels 714 can rotate under the action of the second motor 716, thereby driving the rotation of the conveyor belt 715. At this time, a number of mounting members 514 provided on the conveyor belt 715 can send the sampling cylinders 513 placed thereon one by one to the lower part of the cylinder body 313 where the sampling cylinder assembly is located. Since the first electromagnet 512 provided at the bottom of the mounting rod 511 is magnetically attracted to the second electromagnet provided in the mounting block 515, and at the same time the mounting block 515 and the second electromagnet inside it are fixed to the sampling cylinder 513, before the drive sleeve 314 where the drive bracket is located moves upward, the first electromagnet 512 and the second electromagnet are energized, so that the drive sleeve 314 where the drive bracket is located is connected to the sampling cylinder 513. Then, when the drive sleeve 314 moves upward, the sampling cylinder 513 is docked and communicated with the bottom end of the cylinder body 313, which is used to receive the falling feed additive and complete the collection of the feed additive. When the drive sleeve 314 moves downward, the sampling cylinder 513 is separated from the cylinder body 313. Then, the first electromagnet 512 and the second electromagnet are de-energized. At this time, the conveyor belt 715 continues to rotate to realize the stepping of the next sampling cylinder 513.
