[0012] As a further improvement of the present invention, a reinforcement ring is provided on the outer side of the spiral blade, and the reinforcement ring is connected to the vertical shaft through a connecting frame. The outer side of the fixed plate is fixedly connected to the reinforcement ring, and the outer sides of the sliding plate and the rotating plate are both rotatably connected to the reinforcement ring.

[0013] As a further improvement of the present invention, a rubber strip capable of contacting the inner wall of the storage tank is provided on the outer side of the reinforcement ring.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. By arranging a vertical axis in the storage tank, the vertical axis is connected to the telescopic mechanism, and the telescopic mechanism is connected to the driving motor, so that the driving motor can drive the telescopic mechanism and the vertical axis to rotate, and the telescopic mechanism can drive the vertical axis to move up and down, so that the vertical axis can be raised and lowered while rotating; in addition, by arranging a spiral plate blade structure on the vertical axis, and arranging the spiral plate blade as a structure of a fixed plate, a sliding plate and a rotating plate, and arranging a driving mechanism above the rotating plate, the driving mechanism can drive the rotating plate to rotate, so that the sliding plate can be unfolded in sequence, so that the spiral plate blade is unfolded as a whole, and at this time, the spiral plate blade is circular in the horizontal projection direction, and when the spiral plate blade needs to be closed, the driving mechanism drives the rotating plate to rotate in the opposite direction, so that the rotating plate drives the sliding plate to slide and stack on the fixed plate in sequence. The rotation of the rotating plate allows the spiral plate blade to present a stacked state (unexpanded state) with a fan-shaped projection and a spiral plate-like unfolded state with a circular projection.

[0016] When the spiral blades are in a stacked state (undeployed state), firstly, when feeding the feed, the feeding is avoided from being blocked, that is, when feeding, the spiral blades can be lifted to the uppermost position, and the spiral blades can be rotated to a position away from the feed hopper by the control of the drive motor, so as to facilitate the smooth entry of the feed into the storage tank; secondly, during the feeding process, the fluffy feed can be used for preliminary compaction, and the crispy feed can be crushed, that is, during the feeding process or in the gap of feeding, the telescopic mechanism drives the spiral blades to continuously press down the feed already in the storage tank, and in this process, the drive motor can drive the spiral blades to rotate, thereby adjusting the pressing position of the spiral blades, so as to press down the feed at different positions in the storage tank in all directions, realize the compaction or crushing of the feed, and increase the storage capacity of the storage tank for such feed. Third, during the feeding process, the feed can be broken or spread out, that is, during the process of the feed hopper continuously dropping the feed, the spiral blades continuously rotate at the upper position of the storage tank, thereby breaking and shaking the feed in the falling process to a certain extent, so that the feed is broken and the feed is prevented from being too concentrated under the feed hopper. Fourth, during the feeding process or in the storage state, the feed can be stirred, that is, the spiral blades are adjusted to rotate and move up and down inside the feed. The spiral blades, upper stirring shaft, lower stirring shaft and stirring blades can stir the feed, reduce feed compaction, improve ventilation effect, and reduce feed mildew.

[0017] When the spiral blades are in the expanded state, firstly, after the feeding is completed, the telescopic mechanism is extended and retracted to drive the spiral blades to compact or crush the fluffy feed as a whole. Secondly, the fixed plate, multiple sliding plates and a rotating plate of the spiral blades form a spiral knife structure to crush or stir the feed to a certain extent. That is, after the initial feeding is completed or during long-term storage, the spiral blades can be controlled to rotate and rise or rotate and descend in the feed from time to time. During the movement of the spiral blades, the spiral blades can crush or stir the feed to a certain extent with the structure of the spiral knife. The upper stirring shaft, the lower stirring shaft and the stirring blades can further stir and stir the feed, and the combined effect can reduce the compaction and stickiness between the feed, improve the ventilation and wind effect inside the feed, reduce the mildew of the feed, and improve the storage quality of the feed. Thirdly, during the storage of the feed, it can be used to share the load-bearing weight of the feed and reduce the compaction of the feed at the bottom of the storage tank. That is, during the storage process, especially for For feed with heavier density, the spiral blades can be placed at the middle height of the feed to reduce the pressure on the feed at the lower part of the storage tank, reduce the compaction of the feed, increase the gaps between the feeds, improve the ventilation of the internal feed, and reduce the mildew of the feed; fourthly, it can be used to separate different batches or different types of feeds, that is, for feed that enters the storage tank in batches, the spiral blades can be placed above the first batch of feed in the storage tank before the second batch or different types of feed enters, so as to separate different batches or types of feeds, and facilitate the targeted independent management of different batches or types of feeds in the later stage; fifthly, when sharing the load-bearing weight of the lower feed or separating different feeds, the rotation of the spiral blades can drive the rotation of the upper stirring shaft, the lower stirring shaft and the stirring blades, so as to turn and stir the feed above and below the spiral blades, so as to reduce the compaction of the feed and improve the ventilation uniformity and ventilation effect inside the feed.

[0018] In a word, by adjusting the different states of the spiral blades, various functions of feed processing during feed storage can be solved, and the functionality is strong.

[0019] 2. By setting up a ventilator, a first small air duct is set inside the upper stirring shaft, a second small air duct is set inside the lower stirring shaft, a first air cavity is set inside the rotating plate, a second air cavity is set inside the fixed plate, and two parallel first and second large air ducts are set inside the vertical shaft. The ventilator is connected with the first large air duct through a first hose and connected with the second large air duct through a second hose respectively. An upper ventilation hole is set on the upper stirring shaft, and a lower ventilation hole is set on the lower stirring shaft. The ventilator can ventilate and dry the feed on the upper part of the spiral plate blade through the first large air duct, the first air cavity, the first small air duct, and the upper ventilation hole in sequence, and can ventilate and dry the feed on the lower part of the spiral plate blade through the second large air duct, the second air cavity, the second small air duct, and the lower ventilation hole, thereby improving the ventilation effect inside the feed, drying the feed, reducing moisture inside the feed, and reducing feed mold. In addition, two independent ventilation structures are provided at the upper and lower positions of the spiral blades, so that the two ventilation structures can be controlled independently and separately, thereby enabling ventilation management of the feed at the upper and lower positions of the spiral blades according to actual conditions, or when the spiral blades are in a stacked state, the valve of the first hose can be closed so that the ventilation structure on the upper stirring shaft is in a closed state, and the valve of the second hose can be opened so that the ventilation structure on the lower stirring shaft is in a ventilated state, and the feed can be ventilated in all directions by lifting and lowering the vertical shaft.

[0020] 3. By providing pointed conical cutters at the edges of the sliding plate, the rotating plate and the fixed plate, when the spiral blades rotate in the feed, the feed or feed plate lumps can be crushed and cut, and the resistance of the feed to the spiral blades can be reduced when the spiral blades rotate.

[0021] 4. By arranging at least one telescopic member at the edge of one side of the rotating plate away from the sliding plate, and providing an insertion hole on the fixed plate, when the spiral plate leaves are in the expanded state, the telescopic rod of the telescopic member can be inserted into the insertion hole on the fixed plate. With this arrangement, firstly, during the rotation of the spiral plate leaves, the spikes on the telescopic member can crush the feed or feed blocks, and secondly, the rotating plate and the fixed plate can be connected to a certain extent, thereby improving the overall strength and stability of the spiral plate leaves in the expanded state.

[0022] 5. By providing independent adding ports on the first hose and the second hose, materials (such as anthelmintics, desiccants) can be added to the first hose and / or the second hose according to actual conditions, and the feed above or below the spiral plate blades can be processed separately or together. For example, different batches of feed above and below the spiral plate blades can be treated with targeted dosing.

[0023] 6. By setting a long observation window in the storage tank, it is convenient to observe the condition of the storage tank.

[0024] 7. By arranging a ventilation hole on one side of the storage tank and a ventilation cover on the ventilation hole, the ventilation cover can be opened to ventilate the feed according to actual conditions.

[0025] 8. By providing a reinforcement ring on the outer side of the spiral blade, the reinforcement ring is connected to the vertical shaft through a connecting piece, the outer side of the fixed plate is fixedly connected to the reinforcement ring, and the outer sides of the sliding plate and the rotating plate are rotatably connected to the reinforcement ring. The setting of the reinforcement ring can reinforce and stabilize the spiral blade.

[0026] 9. By providing a rubber strip on the outside of the reinforcement ring, the inner wall of the storage tank can be cleaned during the lifting and lowering of the spiral blades, thereby reducing the accumulation of feed on the inner wall of the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is combined with Figure 1-12 The present invention is further described in detail. For a clearer illustration, only the structures related to the inventive point of the present invention are shown in the figure.

[0042] For the convenience of description, the coordinate system is defined as Figure 2 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0043] The embodiment of the present invention discloses a breeding feed storage device. Figure 1 and Figure 2 A feed storage device for breeding includes a storage tank 1, a leg 33 is arranged on the outside of the storage tank 1, a top cover 2 is arranged on the top of the storage tank 1, a feed hopper 3 is arranged on the top of the top cover 2, and an openable discharge door 4 is arranged on the bottom of the storage tank 1. A transparent long observation window 30 is arranged on the storage tank 1 to facilitate observation of the storage tank 1. In addition, a ventilation hole is arranged on one side of the storage tank 1, and a ventilation cover 31 is arranged on the ventilation hole, so that the ventilation cover 31 can be opened to ventilate the feed according to actual conditions.

[0044] like Figure 2 As shown, the storage tank 1 is provided with a vertical shaft 5, and a telescopic mechanism 6 is provided above the vertical shaft 5 to drive it to rise and fall. The telescopic mechanism 6 can be an electric push rod, and the body of the telescopic mechanism 6 is rotatably connected to the top cover 2 through a bearing. The upper end of the telescopic mechanism 6 extends out of the top of the storage tank 1 and is connected to a driving motor 7 that can drive it to rotate. The driving motor 7 is fixed to the upper part of the top cover 2. Figure 3 , Figure 4 and Figure 5 As shown, a deployable spiral plate blade 8 mechanism is provided at the bottom of the vertical shaft 5, and the spiral plate blade 8 mechanism includes a fixed plate 81, a sliding plate 82 and a rotating plate 83, which are all fan-shaped and of the same size. The fixed plate 81 is fixed to one side of the bottom of the vertical shaft 5, and there are multiple sliding plates 82. In this embodiment, there are four sliding plates 82, and the sum of the fan-shaped angles of all sliding plates 82, one rotating plate 83 and one fixed plate 81 is preferably greater than 400 degrees. Multiple sliding plates 82 are arranged on the top of the fixed plate 81 from top to bottom, and a rotating plate 83 is arranged on the top of the sliding plate 82 of the top layer. Both the sliding plate 82 and the rotating plate 83 are rotatably connected to the vertical shaft 5. Specifically, multiple annular grooves 27 are provided at the bottom of the vertical shaft 5 from bottom to top, and a slide bar 28 that is rotatably matched with the annular groove 27 of the vertical shaft 5 is provided on the sliding plate 82 and the rotating plate 83 on the side close to the vertical shaft 5. There is a rotational connection between the upper and lower adjacent sliding plates 82, between the bottom sliding plate 82 and the fixed plate 81, and between the top sliding plate 82 and the rotating plate 83. Specifically, an arc-shaped slide rail 25 is provided above the fixed plate 81 and the sliding plate 82, and an arc-shaped slide groove 26 that rotates with the arc-shaped slide rail 25 is provided below the sliding plate 82 and the rotating plate 83. Therefore, the bottom sliding plate 82 can rotate on the fixed plate 81 around the vertical axis 5, the upper sliding plate 82 can rotate on the sliding plate 82 of the lower plate around the vertical axis 5, and the rotating plate 83 can rotate on the top sliding plate 82 around the vertical axis 5. A driving mechanism 35 that can drive it to rotate forward and reverse around the vertical axis 5 is provided on the rotating plate 83. The driving mechanism 35 can adopt a travel motor type driving power source commonly used in the prior art, such as a power source of a mobile car or other power source structures. In order to prevent the driving mechanism 35 from being exposed, a protective cover (not shown in the drawings) may be provided on the outer side of the driving mechanism 35 .

[0045] During implementation, the driving mechanism 35 drives the rotating plate 83 to rotate. After the rotating plate 83 rotates forward, it drives all the sliding plates 82 to unfold in sequence. After the rotating plate 83 and the sliding plate 82 are unfolded, the side edge of the rotating plate 83 away from the sliding plate 82 is above the fixed plate 81. After the rotating plate 83 rotates reversely, the rotating plate 83 drives the unfolded sliding plate 82 to rotate counterclockwise in sequence. Finally, the sliding plates 82 are stacked layer by layer above the fixed plate 81. An upper stirring shaft 84 is provided above the rotating plate 83, and a lower stirring shaft 85 is provided below the fixed plate 81. Both the upper stirring shaft 84 and the lower stirring shaft 85 are provided with stirring blades 86.

[0046] In addition, when the rotating plate 83 is rotated and unfolded, the sliding plate 82 connected thereto can be driven to rotate, and after the sliding plate 82 rotates a certain angle, the sliding plate 82 adjacent thereto and below can be driven to rotate in turn. Fig.10 , Fig.11 and Fig.12 A small arc groove 38 is provided above the arc groove 26 of the rotating plate 83 and above the arc groove 26 of the sliding plate 82, and the axis of the small arc groove 38 coincides with the axis of the arc groove 26. A second push block 39 is fixed on the counterclockwise side of the small arc groove 38, and the second push block 39 does not protrude from the bottom surface of the small arc groove 38. A second pushed block 40 is fixed above each arc slide rail 25 at a position corresponding to the small arc groove 38, and the second pushed block 40 is located on the clockwise side of the arc slide rail 25, and the second pushed block 40 does not block the rotation of the small arc groove 38 above it. When the rotating plate 83 rotates clockwise, after the rotating plate 83 rotates a certain angle (greater than 60 degrees), the second pushing block 39 on the rotating plate 83 encounters the second pushed block 40 on the uppermost sliding plate 82, and the second pushing block 39 pushes the second pushed block 40 to push the uppermost sliding plate 82 to rotate, and then the rotating plate 83 drives the uppermost sliding plate 82 to rotate, and then after the uppermost sliding plate 82 rotates a certain angle, the second pushing block 39 on the uppermost sliding plate 82 will encounter the second pushed block 40 on the second sliding plate 82, and the uppermost sliding plate 82 continues to rotate, which will drive the second sliding plate 82 to rotate through the second pushing block 39 and the second pushed block 40, and so on, until all the sliding plates 82 are driven to unfold in sequence.

[0047] In addition, in order to prevent the adjacent sliding plates 82, the sliding plates 82 and the fixed plates 81, and the rotating plates 83 and the sliding plates 82 from being separated during the sliding and unfolding, as shown in FIG. Figure 3 As shown, a stop block 36 is provided at different positions in each of the circular slide grooves 27. The stop block 36 is located at the position where each sliding plate 82 and the rotating plate 83 stop sliding at the corresponding unfolding position, so as to prevent the sliding plate 82 from continuing to slide and sliding out of the fixed plate 81, to prevent the upper sliding plate 82 from sliding out of the lower sliding plate 82, and to prevent the rotating plate 83 from sliding out of the sliding plate 82, thereby ensuring the smooth unfolding of the spiral plate blades 8.

[0048] In addition, if Figure 8 and Fig. 9 As shown, each arc-shaped slide groove 26 of the rotating plate 83 and each arc-shaped slide groove 26 of the sliding plate 82 is provided with a first push block 37 on one side of the instantaneous clockwise direction (along the unfolding direction of the spiral plate leaves 8), so that when the unfolded spiral plate leaves 8 are stacked, that is, the rotating plate 83 drives the sliding plate 82 to rotate counterclockwise, the first push block 37 can drive the sliding plate 82 to rotate and retract in the counterclockwise direction, thereby ensuring the smooth stacking and retraction of the rotating plate 83 and the fixed plate 81.

[0049] In addition, if Figure 3 and Figure 4As shown, the edges of the sliding plate 82, the rotating plate 83 and the fixed plate 81 are all provided with a pointed cone-shaped cutter 21. This arrangement can be used to crush and cut the feed or feed plate lumps when the spiral plate blade 8 rotates in the feed, and secondly, it can reduce the resistance of the feed to the spiral plate blade 8 when it rotates.

[0050] In addition, if Figure 3 and Figure 4 As shown, at least one telescopic member 22 which can be extended and retracted up and down is provided at the edge of one side of the rotating plate 83 away from the sliding plate 82. The telescopic member 22 can also adopt an electric push rod structure. A plurality of spikes 23 are provided on the body of the telescopic member 22. After the rotating plate 83 slides and unfolds, an insertion hole 24 is provided on the fixed plate 81 at a position corresponding to the telescopic rod of the telescopic member 22. The telescopic rod of the telescopic member 22 is inserted into the insertion hole 24. With this arrangement, firstly, during the rotation of the spiral plate leaf 8, the spikes 23 on the telescopic member 22 can crush the feed or feed blocks. Secondly, the rotating plate 83 and the fixed plate 81 can be connected to a certain extent, thereby improving the overall strength and stability of the spiral plate leaf 8.

[0051] In addition, if Figure 6 As shown, a reinforcement ring 32 is provided on the outer side of the spiral blade 8, and the reinforcement ring 32 is connected to the vertical shaft 5 through a connecting frame 34. The outer side of the fixed plate 81 is fixedly connected to the reinforcement ring 32, and the outer sides of the sliding plate 82 and the rotating plate 83 are both rotatably connected to the reinforcement ring 32. The rotatable connection method between the sliding plate 82, the rotating plate 83 and the reinforcement ring 32 can adopt the connection method of the slideway slider commonly used in the prior art. The setting of the reinforcement ring 32 can strengthen and stabilize the spiral blade 8. In addition, a rubber strip (not shown in the figure) that can contact the inner wall of the storage tank 1 is provided on the outer side of the reinforcement ring 32. In the process of the spiral blade 8 rising and falling, the inner wall of the storage tank 1 can be cleaned and cleared, reducing the adhesion of feed on the inner wall of the storage tank 1 and improving the overall functionality.

[0052] In addition, if Figure 6 and Figure 7As shown, the present embodiment also includes a ventilator 9, a first small air duct 10 is arranged inside the upper stirring shaft 84, a second small air duct 11 is arranged inside the lower stirring shaft 85, a first air cavity 12 is arranged inside the rotating plate 83, a second air cavity 13 is arranged inside the fixed plate 81, and two parallel first large air ducts 14 and second large air ducts 15 are arranged inside the vertical shaft 5. The ventilator 9 is connected with the first large air duct 14 through a first hose 16, and is connected with the second large air duct 15 through a second hose 17. Valves are arranged on the first hose 16 and the second hose 17. A ventilation valve 18 is arranged on the vertical shaft 5 at the position after the rotating plate 83 is rotated and unfolded. After the rotating plate 83 slides and unfolds, one end of the first air cavity 12 is connected with the first large air duct 14 through the ventilation valve 18, and the other end is connected with the first small air duct 10. That is, when the rotating plate 83 rotates to the unfolded position, the ventilation valve 18 is opened, so that the first air cavity 12 is connected with the first large air duct 14. One end of the second air chamber 13 is connected to the second large air duct 15, and the other end is connected to the second small air duct 11. The upper stirring shaft 84 is provided with a plurality of upper ventilation holes 19 leading from the outside to the first small air duct 10, and the lower stirring shaft 85 is provided with a plurality of lower ventilation holes 20 leading from the outside to the second small air duct 11.

[0053] By setting the above ventilation structure, the ventilator 9 can ventilate and dry the feed on the upper part of the spiral blade 8 through the first large air duct 14, the first air cavity 12, the first small air duct 10, and the upper ventilation hole 19 in sequence, and can ventilate and dry the feed on the lower part of the spiral blade 8 through the second large air duct 15, the second air cavity 13, the second small air duct 11, and the lower ventilation hole 20, thereby improving the ventilation effect inside the feed, drying the feed, reducing the moisture inside the feed, and reducing the mold of the feed. In addition, two independent ventilation structures are set at the upper and lower positions of the spiral blade 8, so that the two ventilation structures can be controlled independently, so that the feed at the upper and lower positions of the spiral blade 8 can be ventilated according to actual conditions, or when the spiral blade 8 is in a stacked state, the valve of the first hose 16 can be closed, so that the ventilation structure on the upper stirring shaft 84 is in a closed state, and the valve of the second hose 17 can be opened, so that the ventilation structure on the lower stirring shaft 85 is in a ventilation state, and the feed can be ventilated in all directions through the up and down movement of the vertical shaft 5.

[0054] In addition, the first hose 16 and the second hose 17 are both provided with independent adding ports 29, so that materials (such as anthelmintics, desiccants) can be added to the first hose 16 and / or the second hose 17 according to actual conditions, and the feed above or below the spiral plate blade 8 can be processed separately or together. For example, different batches of feed above and below the spiral plate blade 8 can be treated with targeted dosing.

[0055] The present invention sets a vertical shaft 5 in the storage tank 1, and the vertical shaft 5 is connected to the telescopic mechanism 6, and the telescopic mechanism 6 is connected to the driving motor 7. Therefore, the driving motor 7 can drive the telescopic mechanism 6 and the vertical shaft 5 to rotate, and the telescopic mechanism 6 can drive the vertical shaft 5 to move up and down, so that the vertical shaft 5 can be raised and lowered while rotating; in addition, a spiral plate blade 8 structure is set on the vertical shaft 5, and the spiral plate blade 8 is set as a structure of a fixed plate 81, a sliding plate 82 and a rotating plate 83, and a driving mechanism 35 is set above the rotating plate 83. Therefore, the driving mechanism 35 can drive the rotating plate 83 to rotate, so that the sliding plate 82 can be unfolded in turn, so that the spiral plate blade 8 is unfolded as a whole, and at this time, the spiral plate blade 8 is circular in the horizontal projection direction. When the spiral plate blade 8 needs to be closed, the driving mechanism 35 drives the rotating plate 83 to rotate in the opposite direction, so that the rotating plate 83 drives the sliding plate 82 to slide and stack above the fixed plate 81 in turn. The rotation of the rotating plate 83 allows the spiral blades 8 to present a stacked state (undeployed state) projected as a fan and a spiral plate-like expanded state projected as a circle.

[0056] When the spiral blades 8 are in a stacked state (undeployed state), firstly, when feeding the feed, the feeding is avoided from being blocked, that is, when feeding, the spiral blades 8 can be lifted to the uppermost position, and the spiral blades 8 can be rotated to a position away from the feed hopper 3 by the control of the drive motor 7, so as to facilitate the smooth entry of the feed into the storage tank 1; secondly, during the feeding process, the fluffy feed can be used for preliminary compaction, and the crispy feed can be crushed, that is, during the feeding process or the feeding gap, the telescopic mechanism 6 drives the spiral blades 8 to continuously press down the feed already in the storage tank 1, and in this process, the drive motor 7 can drive the spiral blades 8 to rotate, thereby adjusting the pressing position of the spiral blades 8, so as to press down the feed at different positions in the storage tank 1 in all directions, realize the compaction or crushing of the feed, and increase the storage capacity of the storage tank 1 for such feed. Third, during the feeding process, the feed can be broken or spread, that is, during the process of the feed hopper 3 continuously dropping the feed downward, the spiral blade 8 continuously rotates at the upper position of the storage tank 1, thereby breaking and shaking the feed in the falling process to a certain extent, so that the feed is broken and the feed is prevented from being too concentrated under the feed hopper 3. Fourth, during the feeding process or in the storage state, the feed can be stirred, that is, the spiral blade 8 is adjusted to rotate and move up and down inside the feed, and the spiral blade 8, the upper stirring shaft 84, the lower stirring shaft 85 and the stirring blade 86 can stir the feed, reduce the compaction of the feed, improve the ventilation effect, and reduce the mildew of the feed.

[0057] When the spiral blades 8 are in the expanded state, firstly, after the feeding of the feed is completed, the telescopic mechanism 6 is extended and retracted, thereby driving the spiral blades 8 to compact or crush the fluffy feed as a whole; secondly, the fixed plate 81, multiple sliding plates 82 and a rotating plate 83 of the spiral blades 8 form a spiral knife structure to crush or stir the feed to a certain extent, that is, after the initial feeding is completed or during long-term storage, the spiral blades 8 can be controlled to rotate and rise or rotate and descend in the feed from time to time. During the movement of the spiral blades 8, the spiral blades 8 can crush or stir the feed to a certain extent with the structure of the spiral knife, and the upper stirring shaft 84, the lower stirring shaft 85 and the stirring blades 86 can further stir and stir the feed, and work together to reduce the compaction and stickiness between the feeds, improve the ventilation and wind effect inside the feeds, reduce the mildew of the feeds, and improve the storage quality of the feeds; thirdly, during the storage of the feeds, it can be used to share the load-bearing weight of the feeds and reduce the compaction of the feeds at the lower part of the storage tank 1, that is, during the storage process, the spiral blades 8 can be used to share the load-bearing weight of the feeds and reduce the compaction of the feeds at the lower part of the storage tank 1. In particular, for feed with a heavier density, the spiral blade 8 can be placed at the middle height of the feed to reduce the pressure on the feed at the lower position of the storage tank 1, reduce the compaction of the feed, increase the gap between the feeds, improve the ventilation of the internal feed, and reduce the mildew of the feed; fourthly, it can be used to separate different batches or different types of feeds, that is, for feed entering the storage tank 1 in batches, before the second batch or different types of feed enter, the spiral blade 8 can be placed above the first batch of feed in the storage tank 1 to separate different batches or types of feeds, so as to facilitate the targeted independent management of different batches or types of feeds in the later stage; fifthly, when sharing the load-bearing weight of the lower feed or separating different feeds, the rotation of the spiral blade 8 can drive the rotation of the upper stirring shaft 84, the lower stirring shaft 85 and the stirring blade 86, so as to turn and stir the feed at the upper and lower positions of the spiral blade 8 to reduce the compaction of the feed and improve the ventilation uniformity and ventilation effect inside the feed.

[0058] In short, by adjusting the different states of the spiral blades 8, various different functions of feed processing during feed storage can be solved, and the functionality is relatively strong.
