[0068] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0069] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention provides:

[0070] A large-scale precision feeding method for mutton sheep is achieved by feeding equipment, the feeding equipment comprises a storage box 1 and a rake roller 2 horizontally arranged at the bottom of the storage box 1, symmetrical spiral blades 21 are arranged on the circumferential surface of the rake roller 2, a first discharge port 11 and a second discharge port 12 are arranged on both sides of the bottom end of the storage box 1, a quantitative feeding mechanism 3 is arranged at the first discharge port 11 and the second discharge port 12, the quantitative feeding mechanism 3 is provided with a feed port 31 penetrating from top to bottom, a feed roller 32 is rotatably arranged in the feed port 31, a feed trough is arranged on the feed roller 32, the storage box 1 is also provided with a driving mechanism 4 transmission-connected to the rake roller 2 and the feed roller 32, the feeding method comprises the following steps,

[0071] Step 1: Set the first discharge port 11 and the second discharge port 12 on the top of the two feed troughs;

[0072] Step 2, start the driving mechanism 4 to rotate the raking roller 2 and the feeding roller 32, push the feed in the storage box 1 to the top of the first discharge port 11 and the second discharge port 12 through the raking roller 2, and rotate the feeding roller 32 to make the feeding trough with feed on the top rotate to the bottom, thereby putting a certain amount of feed into the feed trough.

[0073] It also includes a moving device for moving the feeding device, so that the feeding device can move on the ground, so that the first discharge port 11 and the second discharge port 12 are respectively suspended on the top of the two feed troughs, so that the moving device can drive the feeding device to move between the two feed troughs along the length direction of the feed troughs, so that a certain amount of forage can be evenly placed on the two feed troughs.

[0074] The fodder is stored in the storage box 1. When the driving mechanism 4 is started, the raking roller 2 can rotate stably in the storage box 1, and the inner cavity of the storage box 1 gradually converges toward its bottom end, so that the fodder can move to the bottom end of the inner cavity of the storage box 1 under the action of the inclined surface.

[0075] Because symmetrical spiral blades 21 are provided on the circumferential surface of the raking roller 2, when the raking roller 2 rotates, the rotating and symmetrical spiral blades 21 can gradually move the grass in the storage box 1 to the two ends of the raking roller 2, so that the grass can evenly fall on the first discharge port 11 and the second discharge port 12, so that the grass can pass through the first discharge port 11 and the second discharge port 12 and fall into the quantitative feeding mechanism 3. Because the feeding roller 32 is connected to the driving mechanism 4 in a transmission manner, the feeding roller 32 can stably rotate in the feeding port 31.

[0076] Because a feeding trough extending along the axial direction is provided on the circumferential surface of the feeding pipe, the grass falls into the feeding trough. When the feeding roller 32 rotates in the feeding port 31, the feeding trough containing the grass rotates to the bottom of the feeding port 31, so that the grass in the first discharge port 11 or the second discharge port 12 can gradually pass through the feeding port 31.

[0077] Since the capacity of the feeding trough is constant, the feeding roller 32 rotates and sends out a constant amount of grass downward, so that the grass can be quantitatively added to the feed trough. At the same time, the rotation speed of the feeding roller 32 can be adjusted to adjust the discharge amount of the grass.

[0078] In this embodiment, the quantitative feeding mechanism 3 is respectively arranged at the first discharge port 11 and the second discharge port 12 of the storage box 1, so that after the raking roller 2 rotates to push the grass to the first discharge port 11 and the second discharge port 12, the rotating feeding roller 32 can put a certain amount of grass into the feed trough at the bottom, thereby realizing accurate feeding of meat sheep.

[0079] like Figure 3 As shown, the feed trough has a side wall 33 and a sliding plate 34 arranged in the side wall 33, and the side surface of the sliding plate 34 is slidably matched with the side wall 33. The feed roller 32 is also provided with an adjustment component for radial movement of the feed roller 32.

[0080] In order to adjust the single feeding capacity of the feed trough, the adjustment component is started so that the sliding plate 34 can move radially along the feed roller 32 in the side plate, thereby adjusting the volume of the feed trough. When the feed roller 32 rotates in the feed port 31, the feeding amount of the feed roller 32 can be adjusted by adjusting the volume of the feed trough.

[0081] like Figure 3 As shown, the first material discharging port 11 and the second material discharging port 12 are both provided with a first parallel material drawing roller 13 and a second material drawing roller 14, a material drawing plate 15 is provided on the circumferential surface of the first material drawing roller 13 and the second material drawing roller 14, and one end of the first material drawing roller 13 and the second material drawing roller 14 are provided with a first gear 16 and a second gear 17 meshing with each other, the first material drawing roller 13 is synchronously connected with the feeding roller 32, and the second material drawing roller 14 is synchronously connected with the raking roller 2.

[0082] In order to enable the grass at the first discharge port 11 and the second discharge port 12 to be quickly gathered at the top of the feeding port 31 to avoid the absence of grass at the top of the feeding port 31, a first parallel feeding roller 13 and a second feeding roller 14 are arranged at the first discharge port 11 and the second discharge port 12. Since the outer ends of the first feeding roller 13 and the second feeding roller 14 are respectively provided with a first gear 16 and a second gear 17 that mesh with each other, the first feeding roller 13 and the second feeding roller 14 can rotate inward in opposite directions in the first discharge port 11 and the second discharge port 12, so that the rotating feeding plate 15 can push the grass at the top of the feeding port 31 downward, and further gather the grass at the top of the feeding roller 32, so that the rotating feeding roller 32 can push the grass to the bottom of the feeding port 31, thereby completing the delivery of the grass.

[0083] like Figure 5 and Fig.10 As shown, the adjustment assembly includes an inclined block 36 arranged on the back side of the sliding plate 34, a push rod 37 arranged in the feed roller 32, and a push block 38 arranged on the circumferential surface of the push rod 37, and the push block 38 is slidably matched with the inclined surface of the inclined block 36.

[0084] By setting an inclined block 36 on the back side of the sliding plate 34, when the push rod 37 slides in the feed roller 32, the push block 38 can move along the axial direction of the feed roller 32. Since the sliding plate 34 can be set in the feed trough along the radial sliding direction of the feed roller 32, when the push block 38 slides, under the action of the inclined surface of the inclined block 36, the sliding block can slide in the feed trough to adjust the volume of the feed trough, and then when feeding, the volume of the feed roller 32 feeding downward in a single time can be adjusted.

[0085] like Figure 5 and Fig.10 As shown, the inclined surface of the inclined block 36 is provided with an engaging block 361 extending along the inclined surface direction thereof, and the outer end of the pushing block 38 is provided with an engaging groove engaged and slidably matched with the engaging block 361 .

[0086] In order to enable the push block 38 to move along the axial direction of the feed roller 32 so that the sliding plate 34 can slide in the feed trough, an interlocking block 361 extending along its length direction is provided on the inclined surface of the inclined block 36, and an interlocking groove that can slide with the interlocking block 361 is provided on the push block 38, so that under the sliding action of the interlocking block 361 and the interlocking groove, the sliding plate 34 cannot be separated from the feed trough, and at the same time, the sliding plate 34 can stably move along the radial direction of the feed roller 32 in the feed trough, so as to adjust the feeding capacity of the feed roller 32.

[0087] like Fig. 9 and Fig.10As shown, the quantitative feeding mechanism 3 also includes a driving push cylinder 39, and the driving push cylinder 39 includes a push rod 391 that can move along the axial direction of the feeding roller 32, and one end of the push rod 391 is fixedly connected to one end of the push rod 37.

[0088] In order to make the push rod 37 slide in the feed roller 32 to adjust the volume of the feed trough, the driving push rod 37 extends along the axial direction of the feed roller 32. When the driving push rod 37 is started, the push rod 391 can drive the push rod 37 to slide in the feed roller 32, so that the push block 38 can slide in the feed roller 32 so that the sliding plate 34 can move radially along the feed roller 32 in the feed trough, and further can stably adjust the volume of the feed trough.

[0089] like Fig.10 As shown, a dovetail groove 371 extending along the axial direction of the push rod 37 is provided on the circumferential surface thereof, and a dovetail block 381 engaged with the dovetail groove 371 is provided on the inner side of the push block 38 .

[0090] In order to enable the push block 38 to be stably set on the circumferential surface of the push rod 37, a dovetail groove 371 is provided on the circumferential surface of the push rod 37 along its axial direction, and a dovetail block 381 that can be engaged with the dovetail groove 371 is provided on the inner side of the push block 38, so as to stably set the push block 38 on the circumferential surface of the push rod 37.

[0091] like Figure 5 As shown, the push block 38 is provided with a threaded hole extending radially along the push rod 37 , a threaded column 310 threadedly connected thereto is provided in the threaded hole, and the threaded column 310 abuts against the dovetail groove 371 along the radial direction of the push rod 37 .

[0092] When the push block 38 is set on the push rod 37 with the dovetail groove 371 through the dovetail block 381, sliding is likely to occur between the dovetail block 381 and the dovetail groove 371. In order to complete the stable connection between the push block 38 and the push rod 37, the threaded column 310 is screwed into the threaded hole so that the threaded column 310 can abut against the dovetail groove 371 along the radial direction of the feed roller 32. Due to the mutual fit between the dovetail groove 371 and the dovetail block 381, when the threaded column 310 abuts against the dovetail groove 371, the push block 38 and the push rod 37 can be stably connected.

[0093] like Figure 6 , Figure 7 and Figure 8As shown, a mounting groove 18 is provided at the bottom end of the material storage box 1, and the raking roller 2 passes through the mounting groove 18. The driving mechanism 4 includes a first transmission roller 41 and a second transmission roller 42 which are arranged in the mounting groove 18 and extend radially along the raking roller 2, and a motor 48 which is arranged in the mounting groove 18 and is transmission-connected to the raking roller 2. The raking roller 2 is provided with a first bevel gear 43 which is coaxial with the raking roller 2, and the second transmission roller 42 is provided with a second bevel gear 44 which meshes with the first bevel gear 43. The first transmission roller 41 is provided with a third gear 45, and the second transmission roller 42 is provided with a fourth gear 46, and the third gear 45 and the fourth gear 46 are meshed with each other. The first transmission roller 41 and the second transmission roller 42 are transmission-connected to the second feed roller 14 on the first discharge port 11 and the second discharge port 12 respectively. The push rod 37 is also provided with a spline sleeve 47 which slides with the dovetail groove 371, and the spline sleeve 47 is transmission-connected to the first feed roller 13.

[0094] When the motor 48 is started, the output shaft of the motor 48 can drive the raking roller 2 to rotate in the storage box 1. Since the feed roller 32 and the second transmission roller 42 are connected by the first bevel gear 43 and the second bevel gear 44, the second transmission roller 42 can stably rotate in the mounting groove 18. The first transmission roller 41 and the second transmission roller 42 can rotate in the opposite direction through the mutually meshing third gear 45 and the fourth gear 46. Since the first transmission roller 41 and the second transmission roller 42 are respectively connected to the first discharge port 11 and the second discharge port 11, The second feed roller 14 on 12 is transmission connected, so that the second feed roller 14 on the first discharge port 11 and the second discharge port 12 can rotate in the opposite direction, and further the first feed roller 13 and the second feed roller 14 in the first discharge port 11 and the second discharge port 12 can rotate inward. Because the first feed roller 13 and the spline sleeve 47 are synchronously connected, the feed rollers 32 at the bottom of the first discharge port 11 and the second discharge port 12 can rotate stably, so that the push rod 37 can slide in the spline sleeve 47 and be guided to rotate by the spline sleeve 47.

[0095] like Figure 2 As shown, a large-scale precision feeding device for mutton sheep comprises a storage box 1 and a rake roller 2 horizontally arranged at the bottom of the storage box 1, symmetrical spiral blades 21 are arranged on the circumferential surface of the rake roller 2, a first discharge port 11 and a second discharge port 12 are arranged on both sides of the bottom end of the storage box 1, a quantitative feeding mechanism 3 is arranged at the first discharge port 11 and the second discharge port 12, the quantitative feeding mechanism 3 is provided with a feeding port 31 penetrating from top to bottom, a feeding roller 32 is rotatably arranged in the feeding port 31, a feeding trough is arranged on the feeding roller 32, and a driving mechanism 4 which is transmission-connected to the rake roller 2 and the feeding roller 32 is also arranged on the storage box 1.

[0096] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
