[0040] See also Figures 1 to 6 .

[0041] The greenhouse-specific bagged fertilizer transport and storage device comprises a weighing conveyor 100, a roller float-out sorting machine 200, a first straightening conveyor 300, a second straightening conveyor 400 and a control circuit 500.

[0042] The upper area of ​​the conveyor belt of the weighing conveyor 100 constitutes a weighing channel 110 for conveying bagged fertilizers. The weighing conveyor 100 is used to weigh the bagged fertilizers.

[0043] The end of the weighing channel 110 is connected to the beginning of the roller float sorting machine 200. The roller float sorting machine 200 is a commercially available product. The roller float sorting machine 200 is divided into two branches from the middle to the end, and the two branches are a good product branch 210 and a bad product branch 220.

[0044] The first correcting conveyor 300 is a belt conveyor. The upper area of ​​the conveyor belt of the first correcting conveyor 300 constitutes a first correcting channel 310 for conveying bagged fertilizers. The end of the good product branch 210 of the roller float-out sorting machine 200 is connected to the starting end of the first correcting conveyor 300. The first correcting conveyor 300 is also provided with a plurality of blocks 320. The plurality of blocks 320 are respectively fixedly connected to the support frame of the first correcting conveyor 300 on both sides of the first correcting channel 310. The plurality of blocks 320 are located on the upper side of the first correcting channel 310. The plurality of blocks 320 are alternately distributed on both sides of the length direction of the first correcting channel 310 in sequence, and the projections of the plurality of blocks 320 in the length direction of the first correcting channel 310 are arranged at equal intervals. There are gaps for bagged fertilizers to pass through between the projection figures of the plurality of blocks 320 in the width direction of the first correcting channel 310.

[0045] The stopper 320 is generally in the shape of a triangle, with a starting end of the stopper 320 close to an edge of a corresponding support frame and a rear end of the stopper 320 extending in the opposite direction toward the center of the first correction channel 310 .

[0046] The second straightening conveyor 400 is a roller conveyor, and the upper side of the second straightening conveyor 400 forms a second straightening channel 410 for conveying bagged fertilizers, and the end of the first straightening channel 310 of the first straightening conveyor 300 is connected to the beginning of the second straightening channel 410 of the second straightening conveyor 400;

[0047] The upper area of ​​the plurality of rollers 420 of the second straightening conveyor 400 constitutes a second straightening channel 410 for conveying bagged fertilizers. The plurality of rollers 420 of the second straightening conveyor 400 rotate synchronously, and the cross-sectional shape of the rollers 420 of the second straightening conveyor 400 is square.

[0048] The rollers 420 of the second straightening conveyor 400 are divided into two groups. The two groups of rollers 420 are spaced apart in sequence. The angles of projections of any two adjacent rollers 420 on the support frame of the second straightening conveyor 400 relative to their respective rotation axes are staggered by 90°.

[0049] Before the bagged fertilizer is put into storage, the bagged fertilizer passes through the special bagged fertilizer conveying and storage device of this greenhouse. The bagged fertilizer is first placed on the weighing channel 110 of the weighing conveyor 100. The weighing conveyor 100 collects the weight information of the bagged fertilizer. The bagged fertilizer is transported from the weighing conveyor 100 to the roller float-out sorting machine 200. The weighing conveyor 100 sends the weight information to the control circuit 500. The control circuit 500 compares the current weight information of the bagged fertilizer with the preset normal weight range.

[0050] If the weight information of the bagged fertilizer is within the normal weight range, when the bagged fertilizer passes through the roller float-out sorting machine 200, it passes through the good product branch 210 to the first correction conveyor 300. The initial posture of the bagged fertilizer is different, and the placement angle of the bagged fertilizer in the lying state cannot be unified. As the first correction conveyor 300 runs, the bagged fertilizer in the lying state will contact with several blocks 320 of the first correction conveyor 300 in turn. The bagged fertilizer is passively corrected to the position on the first correction channel 310 under the action of the blocks 320; the bagged fertilizer It enters the second straightening conveyor 400 through the first straightening conveyor 300. Since the angles of the projections of any two adjacent rollers 420 on the supporting frame of the second straightening conveyor 400 relative to their respective rotation axes are staggered by 90°, the bagged fertilizers are affected by the two groups of rollers 420, and the fertilizers in the bags are relatively evenly distributed in the packaging bags, avoiding the uneven amount of fertilizers in certain areas of the packaging bags. After passing through the first straightening conveyor 300 and the second straightening conveyor 400, the bagged fertilizers are more convenient for subsequent stacking and storage operations.

[0051] If the weight information of the bagged fertilizer is outside the normal weight range, the current bagged fertilizer will pass through the inferior branch 220 when passing through the roller floatation sorting machine 200. Specifically, the roller floatation sorting machine 200 installs a powered oblique roller under the main conveyor. During sorting, the oblique roller floats upward and contacts the bottom of the bagged fertilizer, moving the bagged fertilizer obliquely to the inferior branch 220. Subsequently, workers can unpack and recycle the bagged fertilizer that does not meet the weight requirements at the end of the inferior branch 220.

[0052] The above is only one embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as belonging to the protection scope of the present invention.
