Technical Field

[0001] The utility model belongs to the technical field of microbial agent placement devices, and in particular relates to a microbial agent-based placement device for improving saline-alkali land. Background Art

[0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. The formation of alkaline soil and alkaline soil in my country is mostly related to the accumulation of carbonates in the soil. Therefore, the alkalinity is generally high, and plants can hardly survive in severe saline-alkali soil areas.

[0003] Microbial agents refer to live bacterial preparations made by industrially expanding the target microorganisms (effective bacteria) and using porous materials as adsorbents (such as peat and vermiculite) to absorb the fermentation liquid of the bacteria. This kind of agent is used for seed dressing or root dipping, and has the functions of directly or indirectly improving the soil, restoring soil fertility, preventing soil-borne diseases, maintaining the balance of rhizosphere microbial flora, and degrading toxic substances. The proper use of agricultural microbial agents can increase the yield of agricultural products, improve the quality of agricultural products, reduce the use of chemical fertilizers, reduce costs, improve the soil, and protect the ecological environment.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] like Figure 1-5 As shown, a delivery device for improving saline-alkali land based on microbial agents comprises a frame 1, a wheel 2 is installed at the bottom end of the frame 1, a push handle 3 is welded to one side of the frame 1, a box body 4 is welded to the frame 1, a feed port 5 and a discharge port 6 are respectively arranged at the upper and lower ends of the box body 4, a bottom plate 7 is welded at the discharge port 6, a movable plate 8 is plugged into the box body 4 below the bottom plate 7, a plurality of strip holes 9 are opened on the bottom plate 7 and the movable plate 8, a cloth plate 10 is welded obliquely on the inner wall of the box body 4 below the movable plate 8, an adjusting rod 11 is rotatably connected to one side of the movable plate 8, the adjusting rod 11 is penetrated by a support frame 12, the support frame 12 is welded to the outside of the box body 4, a spring 13 is sleeved on the adjusting rod 11 in the support frame 12, a portion of the adjusting rod 11 located outside the support frame 12 is sleeved on a limit rod 14, and a handle 15 is fixed to the end of the adjusting rod 11 located outside the support frame 12.

[0029] The discharge port 6 at the lower end of the box body 4 is open, the upper part of the box body 4 is square, one side of the middle part of the box body 4 is inclined to the inner side of the box body 4, and the lower part of the box body 4 is square, so that the length of the discharge port 6 of the box body 4 is the same as the length of the box body 4 and the width of the discharge port 6 is smaller than the width of the box body 4. A plurality of support plates 16 are welded between the inner walls on both sides of the lower part of the box body 4. The inclined design of the middle part of the box body 4 is to make the microbial agent better gather at the lower part of the box body 4. The support plate 16 is used to support the movable plate 8.

[0030] The bottom plate 7 is located at the connection between the middle and lower parts of the box body 4. The strip holes 9 on the bottom plate 7 are arranged in a square array. The long sides of the strip holes 9 are parallel to the width direction of the box body 4. The support plate 16 is located below the bottom plate 7 and the position of the support plate 16 is staggered with the position of the strip holes 9. The strip holes 9 are used to allow the microbial inoculant to fall and be placed.

[0031] The strip holes 9 on the movable plate 8 are arranged in the same manner as the strip holes 9 on the bottom plate 7. The movable plate 8 passes through the box body 4 from one side of the long side of the box body 4 and is located between the support plate 16 and the bottom plate 7. A connector 17 is welded to one end of the movable plate 8 located outside the box body 4, and a circular slot 18 is provided on the connector 17.

[0032] When the movable plate 8 moves forward and backward, the strip holes 9 on the movable plate 8 and the strip holes 9 on the bottom plate 7 appear in three states in the vertical direction. One is that they do not overlap at all. At this time, the movable plate 8 completely blocks the strip holes 9 on the bottom plate 7, thereby blocking the bottom plate 7 from dropping materials. This state is used when dropping is not required. The second is partial overlap. At this time, the microbial agent falls from the overlapping strip holes 9, thereby performing controllable dropping. The more overlapping parts there are, the greater the amount of dropping, and vice versa. The third is complete overlap, at which time the maximum amount of dropping is reached.

[0033] The purpose of such design is: if the strip holes 9 are not used, but the bottom plate 7 is removed, and the strip holes 9 on the movable plate 8 are removed at the same time, a structure similar to a plug valve is formed. Although the material can be discharged evenly, the material is discharged only by the gap between the movable plate 8 and the inner wall of the box body 4, and the discharge amount is not easy to control. If the gap is too large, the discharge amount will exceed the amount, and if the gap is too small, the material will be stuck.

[0034] By providing the strip holes 9, the above-mentioned gaps are evenly distributed on the strip holes 9, but the bacterial agent will aggregate. Therefore, the bacterial agent is evenly distributed through the distribution plate 10 below. The bacterial agent falls on the distribution plate 10 and bounces off in a fan shape, thereby achieving the purpose of uniform falling.

[0035] A circular block 19 is welded at one end of the adjusting rod 11, and a cover plate 20 is sleeved on the adjusting rod 11. The block 19 is inserted into the slot 18, and the cover plate 20 presses the block 19 and is bolted to the connecting piece 17. The adjusting rod 11 is rotatably connected to the movable plate 8 through the block 19, the slot 18, and the cover plate 20.

[0036] There are two cover plates 20 , both of which are semicircular, and the two cover plates 20 form a complete ring after being butted together.

[0037] The clamping block 19 is pressed by two cover plates 20 , and when disassembly is required, only the pressing cover needs to be removed, and the adjusting rod 11 can be pulled out from the through hole 22 , so the disassembly is convenient.

[0038] The middle part of the limiting rod 14 is annular, and the two ends of the limiting rod 14 are cylindrical. A thread hole 21 is opened in the middle part of the annular limiting rod 14, and a bolt 24 is threadedly connected to the thread hole 21. The tail end of the bolt 24 is pressed on the adjusting rod 11, and the adjusting rod 11 is sleeved in the inner cavity of the middle part of the annular limiting rod 14.

[0039] By loosening and tightening the bolt 24, the limit rod 14 can be fixed on the adjusting rod 11 in an adjustable position, so that the size of the overlapping portion of the movable plate 8 and the strip hole 9 on the bottom plate 7 can be adjusted, thereby achieving adjustable delivery amount.

[0040] The support frame 12 is in the shape of a door, and is provided with a through hole 22, the shape of which matches the outer contour of the limiting rod 14. The support frame 12 is provided with a slot 23, the shape of which matches the shapes of the cylindrical ends of the limiting rod 14, and the slot 23 is connected to the through hole 22.

[0041] The three sides of the cloth plate 10 are welded to the inner wall of the box body 4, and there is a gap between the other side of the cloth plate 10 and the inner wall of the box body 4, and the side of the cloth plate 10 with the gap between the inner wall of the box body 4 faces the support frame 12. The purpose of this design is to prevent the debris on the ground from entering the box body 4 along the cloth plate 10 when pushing forward.

[0042] The working principle of the utility model is:

[0043] When the microbial agent is released, the handle 15 is pulled to move the movable plate 8 outward. At this time, the strip holes 9 on the bottom plate 7 and the strip holes 9 on the movable plate 8 partially overlap in the vertical direction. The amount of overlap is determined according to the release amount. After determination, the limit rod 14 is fixed to the adjustment rod 11 by the bolt 24, so as to realize the rapid adjustment of the release amount.

[0044] The handle 15 is turned to make the limit rod 14 pass through the through hole 22. After the handle 15 is released, one end of the movable plate 8 is pressed against the inner wall of the box body 4 under the action of the spring 13. At this time, the movable plate 8 completely blocks the strip hole 9 on the bottom plate 7. At this time, the microbial agent is added into the box body 4 through the feed port 5. After the feeding is completed, the handle 15 is pulled to make the limit rod 14 pass through the through hole 22, and the handle 15 is rotated to make the two ends of the limit rod 14 stuck in the card slot 23. The microbial agent in the box body 4 begins to fall onto the cloth plate 10 and bounces in a fan shape, so that it falls evenly on the ground, and the hand push handle 3 is pushed to release the microbial agent.

[0045] When it is necessary to stop feeding, the handle 15 is rotated to allow the limit rod 14 to pass through the through hole 22. After the handle 15 is released, one end of the movable plate 8 is pressed against the inner wall of the box body 4 under the action of the spring 13. At this time, the movable plate 8 completely blocks the strip hole 9 on the bottom plate 7, thereby realizing a rapid stop of feeding. If a material is stuck, repeatedly pulling and releasing the handle 15 can quickly clear the blockage.

[0046] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.
