Description

Technical Field

[0001] The present application relates to the technical field of feed spraying equipment, and in particular to a quantitative sprayer. Background Art

[0002] During the feed production process, many important nutrients need to be added to the feed, such as oil, molasses, enzyme preparations, vitamins, organic acids and other nutrients. These ingredients will be damaged to a great extent during the feed preparation and granulation process. Therefore, in order to avoid the loss of nutrients, these nutrients need to be sprayed on the feed.

[0003] Most existing feed spraying equipment can only perform simple spraying of feed. The final feed quality is closely related to the amount of nutrient sprayed and the amount of feed sprayed. If the amount of nutrient sprayed does not match the amount of feed sprayed, the quality of the final sprayed feed will be affected. Moreover, if the amount of nutrient sprayed far exceeds the amount of feed sprayed, it will result in nutrient waste.

[0004] However, the amount of nutrient sprayed is related to the spraying time, so it is easier to control the amount of nutrient sprayed, while it is more difficult to control the amount of feed sprayed. Therefore, in order to improve the effect and efficiency of feed spraying, a sprayer that can easily control the amount of feed sprayed is urgently needed. Summary of the Invention

[0005] The present application provides a quantitative sprayer, which can facilitate users to control the amount of feed to be sprayed, thereby effectively improving the effect and efficiency of feed spraying.

[0006] This application provides a quantitative spraying machine, which adopts the following technical solutions:

[0007] A quantitative spraying machine comprises a spraying device and a feeding device, wherein the feeding device is arranged above the spraying device;

[0008] The feeding device includes a silo, a feed hopper, and a feeding assembly. The feed hopper is arranged between the silo and the spraying device. The interior of the silo has a storage space for storing feed to be sprayed, and the storage space is communicated with the interior of the spraying device through the feed hopper. The feeding assembly is located in the storage space near the feed hopper. The feeding assembly includes a frame, a plurality of storage units, a plurality of elastic members, a plurality of columns, a plurality of first discharge ports that can be controlled to open and close, and a plurality of remotely controlled positioning members.

[0009] The storage unit is connected to the frame in a sliding manner in the vertical direction, the elastic member is located below the storage unit, the two ends of the elastic member are connected to the storage unit and the frame respectively, and the storage unit can drive the storage unit to slide upward to the limit position and maintain it; the interior of the storage unit has a quantitative space, the column is arranged on the frame, and the storage unit is passed through the vertical direction; the top of the column has a plurality of feeding channels communicating with the storage space, and the bottom of the column has a plurality of discharging channels communicating with the internal space of the feed hopper; the quantitative When the weight of the feed in the space is less than a certain amount, the feed channel is communicated with the quantitative space and the storage unit blocks the discharge channel; when the weight of the feed in the quantitative space reaches a certain amount, the discharge channel is communicated with the quantitative space and the storage unit blocks the feed channel; the first discharge port is located at the bottom of the frame, and the feed discharged from the discharge channel enters the feed hopper through the first discharge port; the positioning member is provided on the frame, and when the weight of the feed in the quantitative space reaches a certain amount, the positioning member drives the storage unit to be fixed in position.

[0010] By adopting the above technical solution, after the feed in the storage space enters the corresponding quantitative space through several feed channels respectively, when the feed entering the quantitative space reaches a certain weight, the feed channel is closed and the discharge channel is connected to the quantitative space, and the positioning member will fix the position state of the storage unit at this time. The user remotely controls the first discharge port to open, so that a certain mass of feed in the quantitative space can enter the spraying device through the feed hopper for spraying. At the same time, the user remotely controls the positioning member to release the positioning of the storage unit, so that the storage unit can slide and reset under the action of several elastic members; it can facilitate the user to control the amount of feed sprayed each time the sprayer sprays the feed, thereby effectively improving the effect and efficiency of feed spraying.

[0011] Optionally, the frame includes an axis body, three horizontal plates and several vertical plates, the three horizontal plates are spaced apart and sleeved on the axis body, and the several vertical plates are respectively arranged between adjacent horizontal plates, and a sliding space for the storage unit to slide is formed between adjacent vertical plates and the two horizontal plates away from the feed hopper; the two ends of the column are respectively connected to the two horizontal plates away from the feed hopper, and a transition space is formed between adjacent vertical plates and the two horizontal plates close to the feed hopper, and the first discharge port is located on the horizontal plate closest to the feed hopper, and the transition space distribution is connected to the feed channel and the first discharge port.

[0012] By adopting the above technical solution, when the quantitative space inside the storage unit has a certain mass of feed, before the user controls the corresponding first discharge port to open, part of the feed in the quantitative space can enter the transition space through the discharge channel under the action of its own gravity. At this time, there is sufficient space above and below the position where the feed is gathered, so that after the subsequent first discharge port is controlled to open, the feed can smoothly pass through the first discharge port into the interior of the feed hopper, reducing the probability that the feed discharge process will be affected due to the feed at the bottom blocking the first discharge port after the first discharge port is controlled to open.

[0020] The column is provided with a first spiral blade in the feed channel. When the frame rotates relative to the silo, the column rotates relative to the frame, and the first spiral blade rotates accordingly to drive the feed in the storage space into the quantitative space through the feed channel.

[0024] Optionally, the storage unit is in a constricted shape at the bottom of the quantitative space toward the feed hopper.

[0025] By adopting the above technical solution, it is possible to further facilitate the feed in the quantitative space to enter the transition space through the discharge channel.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-6 This application is described in further detail.

[0042] An embodiment of the present application discloses a quantitative sprayer for spraying nutrients required for feed production onto the surface of feed particles. The nutrients used for each feed spraying and the feed to be sprayed can be quantified, thereby improving the efficiency and effect of feed spraying and reducing the waste of nutrients during the feed spraying process.

[0043] Reference Figure 1 and Figure 2 The quantitative spraying machine includes a feeding device 1 and a spraying device 2. The spraying device 2 is fixedly mounted on a base (such as the ground), and the feeding device 1 is fixedly mounted above the spraying device 2. In actual application, it is preferred that the feeding device 1 is fixedly mounted above the spraying device 2 via a support frame. In this embodiment, the support frame is omitted in the drawings to facilitate the representation of other structures.

[0044] The feeding device 1 includes a silo 11, a feed hopper 12, and a feeding assembly 3. The silo 11 is used to store feed to be sprayed; the feed hopper 12 is used to guide the feed in the silo 11 into the spraying device 2; and the feeding assembly 3 is used to quantitatively load the feed in the silo 11, allowing the required mass of feed to be sprayed to enter the spraying device 2 through the feed hopper 12.

[0045] Reference Figure 2 and Figure 3 The silo 11 is a cylindrical structure 34 as a whole. The interior of the silo 11 has a storage space 111 for storing feed, and the storage space 111 is in the shape of a cylindrical structure 34 coaxial with the silo 11.

[0046] The feed hopper 12 is funnel-shaped as a whole. The expanded end of the feed hopper 12 is fixedly connected to the bottom of the silo 11 , and the contracted end of the feed hopper 12 is connected to the spraying device 2 and communicates with the interior of the spraying device 2 .

[0047] The loading assembly 3 is installed in the storage space 111 near the feed hopper 12 . The loading assembly 3 includes a frame 31 , a plurality of storage units 32 , a plurality of elastic members 33 , a plurality of columns 34 and a plurality of first discharge ports 36 that can be opened and closed controllably.

[0048] Reference Figure 3 The frame 31 includes a shaft 311, three horizontal plates 312, and a plurality of vertical plates 313. In this embodiment, the frame 31 preferably includes eight vertical plates 313 in total.

[0049] The shaft body 311 is in the form of a cylindrical body 34 . The shaft body 311 is installed in the storage space 111 with its axis vertical and aligned with the axis of the silo 11 .

[0050] The transverse plates 312 are generally annular plate-like structures. Each of the three transverse plates 312 is sleeved and mounted on the shaft body 311, with the axis of the transverse plates 312 coinciding with the axis of the shaft body 311. The three transverse plates 312 are spaced apart along the axis of the shaft body 311, with two of the transverse plates 312 located at either end of the axis of the shaft body 311. In this embodiment, the radial dimensions of the transverse plates 312 are preferably equal to the inner diameter of the silo 11, and the three transverse plates 312 are preferably equally spaced along the axis of the shaft body 311.

[0051] The vertical plates 313 are rectangular plates in overall structure, with eight vertical plates 313 positioned between two adjacent horizontal plates 312. Four of the vertical plates 313 are located between two horizontal plates 312 away from the feed hopper 12. The vertical plates 313 are installed in a vertical position, with their vertical ends fixedly connected to the two adjacent horizontal plates 312 and their horizontal ends fixedly connected to the shaft 311 and the inner wall of the silo 11. The four vertical plates 313 are arranged in a circular array around the axis of the shaft 311, and sliding spaces 314 are formed between two adjacent vertical plates 313 and two adjacent horizontal plates 312, which are adapted to the storage units 32 and allow the storage units 32 to slide vertically.

[0052] The other four vertical plates 313 are located between the two horizontal plates 312 close to the feed hopper 12, and are also installed in a vertical position. They are aligned with the above four vertical plates 313 in the vertical direction, so that a transition space 315 with the same shape as the sliding space 314 is formed between two adjacent vertical plates 313 and two adjacent horizontal plates 312.

[0053] The frame 31 is rotatably connected to the hopper 11, and the rotation axis of the frame 31 coincides with the axis of the shaft 311. The loading assembly 3 also includes a first driving member 35 for driving the frame 31 to rotate. In this embodiment, the first driving member 35 is preferably a servo motor, and the first driving member 35 is preferably fixedly connected to the feed hopper 12 via a support frame.

[0054] The storage unit 32 is a prism 34 with a sector-shaped cross section. The storage unit 32 is located in the sliding space 314 and is vertically slidably connected to the frame 31. The storage unit 32 has a quantitative space 321 for storing a predetermined amount of feed. The shape of the quantitative space 321 is similar to that of the storage unit 32.

[0055] Reference Figure 3 and Figure 4 The storage unit 32 has limitations during its sliding in the sliding space 314. When the storage unit 32 slides upward to the extreme position, the top of the storage unit 32 will fit and abut against the corresponding horizontal plate 312 away from the feed hopper 12; when the storage unit 32 slides downward to the extreme position, the bottom of the storage unit 32 will fit and abut against the corresponding horizontal plate 312 close to the feed hopper 12.

[0056] The plurality of columns 34 corresponds to the plurality of storage units 32 on a one-to-one basis. In this embodiment, the loading assembly 3 preferably includes four storage units 32 and four columns 34 in total.

[0057] The column 34 is mounted on two transverse plates 312 away from the discharge hopper. The column 34 is generally cylindrical, with its axis parallel to the axis of the shaft 311. The two ends of the column 34 are connected to the two transverse plates 312, and the two ends of the column 34 are respectively inserted through and engaged with the two transverse plates 312. The end of the column 34 that penetrates the transverse plate 312 away from the feed hopper 12 blocks the opening 6 formed in the transverse plate 312. The end of the column 34 that penetrates the transverse plate 312 closer to the feed hopper 12 has several openings around it.

[0058] The column 34 passes through the corresponding storage unit 32, and the column 34 and the corresponding storage unit 32 remain in engagement during the sliding process of the storage unit 32. In this embodiment, the position where the column 34 passes through the storage unit 32 is centered.

[0059] The top and bottom of the column 34 respectively have several feed channels 341 and several discharge channels 342. In this embodiment, it is preferred that the top of the column 34 has a total of one feed channel 341, and the top of the feed channel 341 passes through the top of the column 34 and communicates with the storage space 111 above the frame 31, and the bottom of the feed channel 341 has multiple branches, and the multiple branches are distributed in a circular array with the axis of the column 34 as the axis, and the end of each branch passes through the circumferential surface of the column 34 to form an outlet; when the top of the storage unit 32 is in contact with the corresponding horizontal plate 312 away from the feed hopper 12, the feed channel 341 makes the storage space 111 above the frame 31 communicate with the quantitative space 321 inside the storage unit 32, and at this time the bottom of the storage unit 32 maintains a penetration fit with the column 34, that is, there is no space at the bottom of the storage unit 32 for feed to leave the quantitative space 321.

[0060] In this embodiment, the bottom of the column 34 preferably has a discharge channel 342, which surrounds the bottom of the column 34 and has a plurality of outlets; when the bottom of the storage unit 32 is in contact with the corresponding horizontal plate 312 close to the feed hopper 12, the discharge channel 342 makes the quantitative space 321 inside the storage unit 32 communicate with the corresponding transition space 315, and at this time the top of the storage unit 32 is kept in contact with the column 34, that is, there is no space at the top of the storage unit 32 for feed to enter the quantitative space 321.

[0061] Furthermore, the storage unit 32 has a vertically downward constriction structure at the bottom of the quantitative space 321 , so as to facilitate the feed in the quantitative space 321 to enter the transition space 315 through the discharge channel 342 .

[0062] Furthermore, it is preferred that during the sliding process of the storage unit 32, the feed channel 341 is closed when and only when the bottom of the storage unit 32 is in contact with the corresponding horizontal plate 312 close to the feed hopper 12, and at this time the size of the discharge channel 342 can meet the requirements of the feed in the quantitative space 321 entering the transition space 315 through the discharge channel 342.

[0063] Reference Figure 3 and Figure 5 A plurality of elastic members 33 are respectively installed below the plurality of storage units 32. The ends of the elastic members 33 are respectively fixedly connected to the storage units 32 and the adjacent horizontal plate 312 below the storage units 32. The elastic members 33 are capable of driving the storage units 32 to slide upward to the limit position and maintain it. In this embodiment, the elastic members 33 are preferably compression springs.

[0064] When the amount of feed entering the quantitative space 321 through the feed channel 341 is less than a certain amount, there is always a gap between the bottom of the storage unit 32 and the corresponding transverse plate 312 close to the feed hopper 12; when the amount of feed entering the quantitative space 321 through the feed channel 341 just reaches a certain amount, the bottom of the storage unit 32 is in contact with the corresponding transverse plate 312 close to the feed hopper 12.

[0065] Furthermore, the frame 31 is preferably equipped with a plurality of second driving members 37 and a plurality of movable members 38 on a transverse plate 312 adjacent to and below the storage unit 32. The movable members 38 are movably connected to the transverse plate 312, with their movable directions being parallel to the sliding direction of the storage unit 32. The ends of the elastic members 33 distal to the storage unit 32 are fixedly connected to the movable members 38. When the movable members 38 move upward to their extreme positions, the upper end surfaces of the movable members 38 are flush with the upper end surfaces of the transverse plate 312 on which they are located.

[0066] The second driving member 37 is fixedly mounted within the same horizontal plate 312 and is located below the movable member 38. The second driving member 37 is capable of driving the movable member 38 relative to the horizontal plate 312 and can be remotely controlled by a user. In this embodiment, the second driving member 37 is preferably a hydraulic cylinder; since hydraulic cylinders are common in the prior art, they will not be described in detail here and are only briefly illustrated in the accompanying drawings.

[0067] By controlling the second driving member 37 to move the movable member 38, the amount of compression applied to the elastic members 33 can be changed, thereby adjusting the quantitative standard of the feed in the quantitative space 321. When the movable member 38 moves upward, the amount of compression applied to the elastic members 33 increases. At this point, the quantitative space 321 requires more feed before the weight of the feed forces the storage unit 32 to slide downward to its limit position, overcoming the force applied by the elastic members 33. When the movable member 38 moves downward, the amount of compression applied to the elastic members 33 decreases. At this point, the quantitative space 321 requires less feed before the weight of the feed forces the storage unit 32 to slide downward to its limit position, overcoming the force applied by the elastic members 33.

[0068] Reference Figure 4 and Figure 6 Furthermore, in order to drive the storage unit 32 downward to the limit position after the feed in the quantitative space 321 reaches a certain amount, the storage unit 32 can slide back to its original position only after the feed in the quantitative space 321 is completely discharged. A number of positioning parts 39 are also fixedly installed on the frame 31.

[0069] The plurality of positioning members 39 correspond to the plurality of storage units 32 in a one-to-one manner. In this embodiment, the loading assembly 3 preferably includes a total of four positioning members 39. In this embodiment, the positioning member 39 is preferably a remotely controlled electric latch, and the plurality of positioning members 39 are preferably fixedly mounted on the circumference of the shaft 311.

[0070] The storage unit 32 has an engaging slot 322 at one end thereof, adjacent to the corresponding positioning member 39, into which the positioning member 39 is inserted and engaged. When the storage unit 32 slides downward to its limit position, the positioning member 39 is triggered, causing the positioning member 39 to engage with the storage unit 32 and restrict the vertical movement of the storage unit 32. When the storage unit 32 needs to be slid back to its original position, the user remotely controls the positioning member 39 to release the positioning function of the storage unit 32. In this embodiment, since the electrically controlled latch and the method of remotely controlling the electrically controlled latch are both common prior art, they will not be described in detail herein, and the positioning member 39 is only briefly illustrated in the accompanying drawings.

[0071] Reference Figure 3 and Figure 4 The first discharge ports 36 correspond to the transition spaces 315 in a one-to-one manner. In this embodiment, the loading assembly 3 preferably includes four first discharge ports 36 and four transition spaces 315. The first discharge ports 36 are located on the horizontal plate 312 closest to the feed hopper 12, and the first discharge ports 36 communicate with the corresponding transition spaces 315.

[0072] A movable cover is mounted on the horizontal plate 312 closest to the feed hopper 12 to control the opening and closing of the first discharge port 36. In this embodiment, the cover is preferably movable by a pivoting connection, and its rotation can be remotely controlled. In this embodiment, since the cover with the above-mentioned function is common in the prior art, it will not be described in detail here, and only a brief description is provided in the accompanying drawings.

[0073] Furthermore, to reduce the probability of the feed remaining on the inner wall of the feed hopper 12 after being discharged into the feed hopper 12 through the first discharge port 36, a plurality of scrapers 4 are fixedly mounted below the horizontal plate 312 at the bottom of the frame 31. In this embodiment, preferably, a total of four scrapers 4 are fixedly mounted below the horizontal plate 312 at the bottom of the frame 31, and the four scrapers 4 are arranged in a circular array around the axis of the shaft 311.

[0074] The tops of the scrapers 4 are fixedly connected to the corresponding transverse plates 312, and the bottoms of the scrapers 4 are located inside the feed hopper 12, with one end surface of the bottom of the scrapers 4 abutting against the inner wall of the feed hopper 12. As the first drive member 35 drives the frame 31 to rotate relative to the hopper 11, the scrapers 4 also rotate relative to the feed hopper 12, thereby scraping off any feed remaining on the inner wall of the feed hopper 12, allowing it to pass through the feed hopper 12 and into the spraying device 2.

[0075] Furthermore, to facilitate the flow of feed from the storage space 111 above the frame 31 into the quantitative space 321 through the feed channel 341, the loading assembly 3 further includes a scraping member 5 for scraping the feed above the top transverse plate 312 of the frame 31 and forcing the feed into the feed channel 341. In this embodiment, the scraping member 5 preferably abuts against the transverse plate 312 at the top of the frame 31, and is radially arranged with the center of the adjacent transverse plate 312 as the center. The scraping member 5 is also fixedly connected to the silo 11.

[0076] During the rotation of the frame 31 relative to the silo 11 , the scraping member 5 rotates relative to the horizontal plate 312 at the top of the frame 31 , thereby scraping the feed above the horizontal plate 312 at the top of the frame 31 , making it easier for the feed to enter the quantitative space 321 through the feed channel 341 .

[0077] Furthermore, the loading assembly 3 preferably includes a ring gear 346 and several gears 345. The two ends of the column 34 along its axis are preferably rotatably connected to the corresponding horizontal plate 312, with the axis of rotation of the column 34 coinciding with its own axis. The gears 345 correspond one-to-one with the columns 34. In this embodiment, the loading assembly 3 preferably includes four gears 345.

[0078] The gear 345 is fixedly mounted on the bottom of the column 34 . The axis of the gear 345 coincides with the axis of the column 34 . The gear 345 is located between the two horizontal plates 312 close to the feed hopper 12 .

[0079] The ring gear 346 is fixedly mounted inside the silo 11. The outer end surface of the ring gear 346 abuts against the inner wall of the silo 11, and the axis of the ring gear 346 coincides with the rotation axis of the frame 31. The ring gear 346 surrounds and meshes with the four gears 345 simultaneously. The vertical plates 313 that form the transition space 315 each have a recessed groove that allows for the ring gear 346 to move in. During the rotation of the frame 31, there is no positional interference with the ring gear 346, and the gap between the ring gear 346 and the vertical plates 313 cannot allow feed to enter the transition space 315 to pass through.

[0080] A first spiral blade 343 is fixedly mounted on the top of the column 34 within the feed channel 341, with the spiral centerline of the first spiral blade 343 coinciding with the axis of the column 34. When the frame 31 rotates relative to the silo 11, the relative movement of the gear 345 and the ring gear 346 causes the column 34 to rotate relative to the frame 31. The rotation of the first spiral blade 343 guides feed located above the cross plate 312 at the top of the frame 31 into the feed channel 341, thereby accelerating the flow of feed through the channel.

[0081] A second spiral blade 344 is also sleeved and mounted on the circumference of the cylinder 34, with the spiral centerline of the second spiral blade 344 coinciding with the axis of the cylinder 34. The second spiral blade 344 is located in the quantitative space 321 and remains in the quantitative space 321 during the sliding of the storage unit 32. When the frame 31 rotates relative to the silo 11, the relative movement of the wheel and the ring gear 346 drives the cylinder 34 to rotate relative to the frame 31. At this time, the second spiral blade 344 rotates accordingly, guiding the feed in the quantitative space 321 into the discharge channel 342, while also accelerating the speed at which the feed enters the transition space 315 from the quantitative space 321.

[0082] Reference Figure 1 and Figure 2 The spraying device 2 includes a body 21, a pot 22, a third drive member 23, a spraying member 24, and a feed box 25. The body 21 is used to provide a space isolated from the outside for spraying the feed; the pot 22 serves as a carrier for spraying the feed, that is, the feed is sprayed inside the pot 22; the third drive member 23 is used to drive the feed inside the pot 22 to move, so that the nutrients are sprayed evenly on the surface of the feed; the spraying member 24 is used to spray the nutrients onto the surface of the feed; and the feed box 25 is used to store nutrients and provide raw materials for the spraying member 24.

[0083] The body 21 preferably has an overall rectangular parallelepiped structure and is hollow. A control panel 211 is provided on the surface of the body 21 for controlling the first drive member 35, the second drive member 37, the third drive member 23, the positioning member 39, and the opening and closing of the first discharge port 36. Since remote control is a common technology, the principles of this function will not be elaborated upon here.

[0084] The pot body 22 is spherical in structure and includes an outer shell 221 and an inner shell 222, with the outer shell 221 enclosing the inner shell 222. The outer shell 221 is located inside the body 21 and is fixedly connected to the body 21. The inner portion of the outer shell 221 has an inner cavity 2211 that matches the inner shell 222. The inner cavity 2211 has an opening 6 formed at one end of the outer shell 221, and the outer shell 221 is installed with the opening 6 tilted upward. The inner shell 222 has a spraying space 2221 inside for spraying feed. The spraying space 2221 also has an opening 6 formed at one end of the inner shell 222. In this embodiment, the opening 6 on the outer shell 221 and the opening 6 on the inner shell 222 are preferably both circular and of equal size.

[0085] The outer surface of the inner shell 222 fits against the wall of the inner cavity 2211, and the inner shell 222 is rotatably connected to the outer shell 221. The rotation axis of the inner shell 222 coincides with the axis of the opening 6 on the inner shell 222, and the axis of the opening 6 on the outer shell 221 coincides with the rotation axis of the inner shell 222, and the opening 6 on the outer shell 221 is connected to the opening 6 on the inner shell 222.

[0086] The end of the feed hopper 12 away from the silo 11 is fixedly connected to the machine body 21, and the feed hopper 12 has a pipe extending in an inclined downward direction toward the pot body 22. The end of the pipe away from the feed hopper 12 passes through the opening 6 of the outer shell 221 and the opening 6 of the inner shell 222 and extends into the spraying space 2221.

[0087] The third driving member 23 is fixedly mounted on the end of the outer shell 221 away from the opening 6 thereof, and the third driving member 23 can drive the inner shell 222 to rotate relative to the outer shell 221. In this embodiment, the third driving member 23 is preferably a servo motor.

[0088] The material box 25 is also fixedly installed on the base (ie, the ground), and the material box 25 is located on one side of the machine body 21 .

[0089] The spraying element 24 is fixedly mounted on the body 21, extending through the top of the body 21 and located on one side of the feed hopper 12. One end of the spraying element 24 also extends through the opening 6 of the outer shell 221 and the opening 6 of the inner shell 222 into the spraying space 2221 and is centered therein. The other end of the spraying element 24 is connected to a pipe that is connected to the feed box 25. Nutrients in the feed box 25 can be pumped into the spraying element 24 via a liquid pump, and the spraying element 24 can evenly spray the nutrients onto the surface of the feed in the spraying space 2221. In this embodiment, since the use of the spraying element 24 and the feed box 25 in combination is conventional in the art, neither will be described in detail herein, and both are only briefly illustrated in the accompanying drawings.

[0090] The control panel 211 can control the speed at which the nutrients in the material box 25 are fed into the spraying member 24 and the spraying time, thereby enabling the user to conveniently control the amount of the nutrients sprayed.

[0091] The inner shell 222 has a plurality of leakage openings 2222 arranged around the inner shell 222 in a circular array about the inner shell 222's axis of rotation. The bottom of the outer shell 221 also has a second discharge opening 2212 that can be controlled to open and close. When the inner shell 222 is rotated to any position, a leakage opening 2222 can always communicate with the second discharge opening 2212. When the second discharge opening 2212 is opened, the sprayed feed in the spraying space 2221 can be discharged through the second discharge opening 2212. The discharged feed is then sent to the next feed processing equipment via a pipeline. In this embodiment, the opening and closing of the second discharge opening 2212 can preferably also be controlled on the control panel 211, and the aforementioned pipeline and the next feed processing equipment are omitted in the accompanying drawings.

[0092] The implementation principle of a quantitative spraying machine in the embodiment of the present application is:

[0093] During the rotation of the frame 31, the feed to be sprayed in the storage space 111 first enters the quantitative space 321 through the feed channel 341. At this time, the scraper 5 rotates relative to the frame 31 to drive the feed in the storage space 111 into the feed channel 341. At this time, the first spiral blade 343 rotates along with the rotation of the column 34, further facilitating the feed in the storage space 111 to enter the quantitative space 321 through the feed channel 341.

[0094] When the feed enters the quantitative space 321, the gradually increasing gravity of the feed will drive the storage unit 32 to overcome the force of the several elastic members 33 and slowly slide downward; when the feed in the quantitative space 321 reaches a certain amount, the bottom of the storage unit 32 contacts and abuts against the corresponding horizontal plate 312, at which time the feeding channel 341 is closed, the discharging channel 342 is opened, and the storage unit 32 is positioned by the corresponding positioning member 39; and at this time, the user can operate the corresponding first discharge port 36 to open the control panel 211, so that the feed in the quantitative space 321 enters the transition space 315 through the discharge channel 342 and then enters the feed hopper 12 through the first discharge port 36, and then enters the spraying space 2221 through the feed hopper 12, so that the quantitative feed to be sprayed can be sent to the spraying device 2 for spraying; thereafter, the positioning member 39 is controlled by the control panel 211 to release the positioning of the storage unit 32, and the storage unit 32 can slide back to repeat the above steps;

[0095] After a certain amount of feed is delivered into the spraying space 2221, the user can control the rotation of the inner shell 222 through the control panel 211, and at the same time control the spraying part 24 to evenly spray the nutrients in the material box 25 onto the surface of the feed in the spraying space 2221. A certain amount of feed to be sprayed is sprayed with a certain amount of nutrients, thereby obtaining feed with a better spraying effect and significantly improving the feed spraying efficiency.

[0096] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
