[0030] Through the mixing device, the feed can be directly fed into the feeding trough for beef cattle after mixing. When mixing, the bidirectional motor works to drive the stirring assembly and the moving assembly at the same time. The first stirring rod and the second stirring rod in the stirring assembly evenly mix the feed entering from the feed inlet. At this time, the transmission shaft in the moving assembly rotates to drive the moving wheels to rotate, and the entire device is driven by the moving wheels to move along the feeding trough. During the movement, the feed is stirred and mixed;

[0031] When moving to the other end of the feeding trough, the bidirectional motor works in the reverse direction and at this time the adjusting assembly also works. Due to the reverse rotation of the bidirectional motor, the moving wheels rotate in the reverse direction to drive the mixing device to move back. The adjusting assembly drives the mixing barrel to rotate so that the discharge port moves to the blanking pipe. The feed in the mixing barrel is discharged into the feeding trough from the discharge port and the blanking pipe through the second stirring rod and the harrow teeth in the stirring assembly. The movement of the mixing device can be used for comprehensive blanking of the feeding trough, which is convenient for the feeding of beef cattle. Description of the Drawings

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0041] Next, the embodiments of the present invention will be described according to its overall structure.

[0042] Embodiment

[0043] Please refer to Figure 1 , a fattening method for beef cattle to save costs and increase efficiency, including the following steps:

[0044] Step 1. Fattening

[0045] 1. Continuous fattening of replacement heifers:

[0046] The replacement heifers start fattening at 7 - 8 months old for about 10 months, divided into 3 stages. Using the method of drylot feeding and a complete diet, the growing cattle are kept with a relatively high daily weight gain until they reach the slaughter weight and are sold. Generally, they are fattened to 15 - 18 months old and sold when the weight reaches 500 - 600 kg.

[0047] Early fattening stage: about 1 month; free access to feed and water; the ratio of concentrate to roughage in the diet is 35%:65%, and the crude protein level is 13% - 14%. The main purpose is to let the calves adapt to the fattening environment, and also to deworm, dehorn, and prevent diseases.

[0048] Mid - fattening stage: 6 - 7 months; free access to feed and water; the ratio of concentrate to roughage in the diet is 45%:55%, and the crude protein level of the diet is 11% - 12%.

[0049] Late fattening stage: about 2 months; free access to feed and water; the ratio of concentrate to roughage in the diet is about 55%:45%, and the crude protein level in the diet is 10%.

[0050] 2. Short - term fattening of feeder cattle:

[0051] Purchase feeder cattle at 1 - 1.5 years old with a weight of 300 - 400 kg. After 4 - 6 months of fattening, they are sold when the weight reaches over 550 kg. Generally, it is divided into three stages:

[0052] The first stage: about 1 month, which requires 7 - 10 days to recover and adapt, and gradually transition to the fattening diet.

[0053] The ratio of concentrate to roughage is 30%:70%, and the crude protein level of the diet is about 12%. The concentrate is gradually increased to 2.5 kg.

[0054] The second stage: 1 - 2 months, the dry matter gradually increases to 7 - 8 kg, the crude protein is about 11%, and the ratio of concentrate to roughage is 60%:40% or 70%:30%, with a daily weight gain of over 1.3 kg.

[0055] The third stage: 61 - 120 days, the dry matter gradually increases to 9 - 10 kg, the crude protein is about 10%, and the ratio of concentrate to roughage is 90%:10% or 80%, with a daily weight gain of about 1.5 kg. The maximum amount of concentrate fed is 6 - 7 kg.

[0056] Step 2. Feeding method: Group the cattle according to age and weight for feeding. It is appropriate to have 10 - 12 heads in each group. Adopt the method of total mixed ration feeding, and feed once in the morning and once in the evening.

[0057] Step 3: Deworming and strengthening the stomach. At 10 - 12 months old, deworm once with Chongkexing or levamisole. The oral dose of Chongkexing per cow is 0.1 grams per kilogram of body weight; the oral dose of levamisole per cow is 8 milligrams per kilogram of body weight. Use Jianweisan or rhubarb soda tablets to strengthen the stomach and increase appetite.

[0058] The formula for roughage is: silage 20% - 30%, straw feed 10% - 20%, high-quality forage 70% - 50%; the formula for concentrate is: corn 60% - 70%, rapeseed meal 15% - 25%, wheat bran 6% - 10%, beef cattle premix 2% - 5%, rumensin 0.1% - 0.2%, salt 0.5% - 1.5%, baking soda 1% - 2%. The feeds are all mixed using the mixing device 8.

[0059] This cost-saving and efficiency-increasing fattening method for beef cattle is different from traditional beef cattle breeding. It entirely uses rapeseed meal instead of soybean meal and cottonseed meal, and adopts a feeding method of once a day instead of the traditional twice a day. At the same time, during the three growth stages of beef cattle, namely the calf stage, bone growth stage, and rapid growth stage, deworm for 7 consecutive days. After deworming, use Jianweisan and Jianpisan to regulate the spleen and stomach and increase appetite. Through this adjustment of the feed formula and the change in the number of feedings, and deworming and conditioning the gastrointestinal tract of beef cattle at different feeding times, it can maximize the growth potential of beef cattle on the basis of saving breeding costs, improve the growth rate of beef cattle, with reasonable nutritional collocation, thereby improving economic benefits and reducing labor costs, equipment operation costs, and loss costs.

[0060] The electrical components in the device are all controlled by an external controller. Initially, the discharge port 301 of the mixing barrel 3 intersects with the feeding pipe 201, and the discharge port 301 is blocked by the inner wall of the housing 2.

[0061] For the embodiment, please refer to Figures 2 - 5, the mixing device 8 includes a housing 2 and a mixing barrel 3 disposed inside thereof. Feeding troughs 1 are provided on both sides of the housing 2. Feeding pipes 201 are opened above the outer walls on both sides of the housing 2 at the positions of the feeding troughs 1. Guide blocks 101 are provided on the outer walls of both feeding troughs 1 close to the housing 2. Strip-shaped grooves 1011 are opened on the upper and lower surfaces of the two guide blocks 101. Guide grooves 202 matching the guide blocks 101 are opened on the outer walls of both sides of the housing 2 at the positions of the guide blocks 101. First balls 2021 are embedded in the top and bottom walls of the two guide grooves 202. Each first ball 2021 is in contact with the inner wall of the strip-shaped groove 1011. The top of the mixing barrel 3 is open and its outer wall is in contact with the inner cavity wall of the housing 2. Discharge ports 301 are opened at the positions of the feeding pipes 201 at the bottoms of the outer walls on both sides of the mixing barrel 3. A stirring assembly 5 is provided at the inner bottom of the mixing barrel 3, and adjusting blocks 303 are symmetrically provided at the top of the inner wall of the mixing barrel 3. A feeding port 203 is opened on the upper surface of the housing 2. Adjusting assemblies 4 are provided on both sides of the feeding port 203 on the inner top wall of the housing 2. The two adjusting assemblies 4 are matched with the adjusting blocks 303. A moving assembly 7 is provided on the lower surface of the housing 2, and a bidirectional motor 6 is provided below the mixing barrel 3 inside the housing 2. The two output ends of the bidirectional motor 6 are respectively connected to the stirring assembly 5 and the moving assembly 7.

[0062] When feeding beef cattle, the staff sequentially feeds the concentrate feed formula in the above text into the mixing barrel 3 inside the housing 2 from the feeding port 203. At this time, the bidirectional motor 6 is started through an external controller. The bidirectional motor 6 drives the stirring assembly 5 and the moving assembly 7 to work through the two output ends respectively. The stirring assembly 5 works to mix the feed in the mixing barrel 3. At the same time, the moving assembly 7 drives the mixing device 8 to move along the guide block 101 provided on the outer wall of the feeding trough 1. During the movement, the embedded first ball 2021 will roll along the strip-shaped groove 1011 to improve the moving effect until it moves from one end of the feeding trough 1 to the other end. During this process, the feed can be fully stirred. Then the adjusting assembly 4 works, drives the mixing barrel 3 to rotate through the adjusting block 303, and makes the discharge port 301 communicate with the feeding pipe 201. At this time, the bidirectional motor 6 works in the reverse direction, and drives the stirring assembly 5 and the moving assembly 7 to work in the reverse direction as well. At this time, the moving assembly 7 drives the mixing device 8 to return along the route. The stirred feed is pushed out from the discharge port 301 and the feeding pipe 201 under the action of the stirring assembly 5 and falls into the feeding trough 1 passing below, so that the feeding can be spread after mixing during feeding, and at the same time, the residue in the mixing barrel 3 can be reduced.

[0063] For the embodiment, please refer to Figures 3 - 6, adjustment grooves 3031 are formed in the inner walls of both adjustment blocks 303, internal toothed channels 3032 are provided in both adjustment grooves 3031, both adjustment blocks 303 are arc-shaped, second balls 302 are symmetrically embedded in the lower surface of the mixing barrel 3, an annular groove 204 is formed in the inner cavity bottom plate of the housing 2, and both second balls 302 are in contact with the inner wall of the annular groove 204. The two adjustment assemblies 4 include trapezoidal blocks 401. Mounting grooves 4011 matching the adjustment blocks 303 are formed in the arc surfaces of both trapezoidal blocks 401. Rotating shafts 403 are vertically provided in both mounting grooves 4011. Driving gears 402 are sleeved on both rotating shafts 403. Both driving gears 402 are meshed and connected with the internal toothed channels 3032. Adjustment motors 404 are installed inside both trapezoidal blocks 401. The output ends of both adjustment motors 404 are flange-connected to the bottom ends of the rotating shafts 403. Both trapezoidal blocks 401 are fixedly connected to the inner top wall of the housing 2. Both driving gears 402 are fixedly installed on the rotating shafts 403. Both adjustment motors 404 are fixed in the trapezoidal blocks 401 by bolts. The top ends of both rotating shafts 403 are rotatably connected to the top walls of the mounting grooves 4011.

[0064] When the adjustment motor 404 in the adjustment assembly 4 works, its output end drives the driving gear 402 to rotate through the rotating shaft 403. The rotating driving gear 402 drives the adjustment block 303 to move in the adjustment groove 3031 through the meshed internal toothed channel 3032. The moving adjustment block 303 drives the mixing barrel 3 to rotate along the inner cavity wall of the housing 2. The rotating mixing barrel 3 drives the second balls 302 to roll along the annular groove 204 to improve the rotating effect of the mixing barrel 3 until the discharge port 301 formed in the outer wall of the mixing barrel 3 communicates with the blanking pipe 201, and then the adjustment motor 404 stops working, thus facilitating the discharging process of the feed.

[0065] For the embodiment, please refer to Figure 3 , the stirring assembly 5 includes a stirring shaft 501. Two groups of first stirring rods 502 and one group of second stirring rods 503 are successively arranged on the outer wall of the stirring shaft 501. The second stirring rods 503 are inclined, and a plurality of rake teeth 5031 are provided on the lower surfaces of the second stirring rods 503. The bottom ends of the plurality of rake teeth 5031 are in contact with the sloping inner bottom plate of the mixing barrel 3. One output end of the bidirectional motor 6 penetrates through the bottom wall of the mixing barrel 3 and is fixedly connected to the stirring shaft 501. The two groups of first stirring rods 502 are located above the second stirring rods 503. The two groups of first stirring rods 502 and one group of second stirring rods 503 are fixedly connected to the outer wall of the stirring shaft 501, and the second stirring rods 503 are longer than the first stirring rods 502. The plurality of rake teeth 5031 are fixedly connected to the second stirring rods 503.

[0066] The two-way motor 6 operates, and one of its output ends drives the connected stirring shaft 501 to rotate. The rotating stirring shaft 501 drives the first stirring rod 502 and the second stirring rod 503 connected to the outer wall to rotate. The first stirring rod 502, the second stirring rod 503, and the rake teeth 5031 perform mixing treatment on the feed in the mixing barrel 3. When discharging, the second stirring rod 503 and the rake teeth 5031 can also push the feed to discharge it from the discharge port 301 and the feeding pipe 201. At the same time, the rake teeth 5031 can prevent the feed from remaining in the mixing barrel 3.

[0067] For the embodiment, please refer to Figure 3 and Figure 7 As shown in FIGS. 5 and 6, the moving assembly 7 includes mounting brackets 705 symmetrically installed on both sides of the lower surface of the housing 2. Below the two mounting brackets 705, moving wheels 7042 are movably installed. A transmission shaft 704 is provided between the two mounting brackets 705. Both ends of the transmission shaft 704 penetrate through the side walls of the mounting brackets 705 and are connected to the hubs of the moving wheels 7042. A protective housing 701 is provided at the center of the lower surface of the housing 2. The other output end of the two-way motor 6 is connected to a rotating shaft 702. The bottom end of the rotating shaft 702 extends into the protective housing 701, and a horizontal bevel gear 703 is sleeved on the outer wall. One side below the horizontal bevel gear 703 is meshed and connected with a vertical bevel gear 7041. The vertical bevel gear 7041 is sleeved on the transmission shaft 704. The two mounting brackets 705 are connected to the housing 2 by bolts. The parts of the two ends of the transmission shaft 704 in contact with the mounting brackets 705 are rotatably connected, and the ends of the transmission shaft 704 are fixedly connected to the moving wheels 7042. The protective housing 701 is welded to the housing 2. The transmission shaft 704 penetrates through the protective housing 701 and is rotatably connected to the contact part. The horizontal bevel gear 703 is fixedly installed on the rotating shaft 702, and the vertical bevel gear 7041 is fixedly installed on the transmission shaft 704.

[0068] The other output end of the two-way motor 6 drives the connected rotating shaft 702 to rotate. The rotating rotating shaft 702 drives the horizontal bevel gear 703 to rotate. The rotating horizontal bevel gear 703 drives the meshed vertical bevel gear 7041 to rotate. The rotating vertical bevel gear 7041 drives the transmission shaft 704 to rotate. The transmission shaft 704 drives the moving wheels 7042 connected to the ends to rotate. Thus, the housing 2 can be driven to move along the path through the moving wheels 7042. While moving, it cooperates with the stirring assembly 5 to uniformly mix and discharge the feed.

[0069] The working principle of the present invention is as follows: When feeding beef cattle, the staff feeds the concentrate feed formula described above into the mixing barrel 3 inside the housing 2 from the feed inlet 203 in sequence. At this time, the bidirectional motor 6 is started through an external controller. The bidirectional motor 6 drives the stirring assembly 5 and the moving assembly 7 to work through its two output ends respectively. One output end of the bidirectional motor 6 drives the connected stirring shaft 501 to rotate. The rotating stirring shaft 501 drives the first stirring rod 502 and the second stirring rod 503 connected to the outer wall to rotate. The first stirring rod 502, the second stirring rod 503 and the rake teeth 5031 perform mixing treatment on the feed in the mixing barrel 3. The other output end of the bidirectional motor 6 drives the connected rotating shaft 702 to rotate. The rotating rotating shaft 702 drives the horizontal bevel gear 703 to rotate. The rotating horizontal bevel gear 703 drives the meshing vertical bevel gear 7041 to rotate. The rotating vertical bevel gear 7041 drives the transmission shaft 704 to rotate. The transmission shaft 704 drives the moving wheel 7042 connected to the end to rotate. The housing 2 is driven to move through the moving wheel 7042. The moving housing 2 moves along the path between the two feeding troughs 1 and the guiding blocks 101 arranged on the outer wall until it moves from one end of the feeding trough 1 to the other end. During this process, the feed can be fully stirred. Then, the adjusting motor 404 in the adjusting assembly 4 works. Its output end drives the driving gear 402 to rotate through the rotating shaft 403. The rotating driving gear 402 drives the adjusting block 303 to move in the adjusting groove 3031 through the meshing inner track teeth 3032. The moving adjusting block 303 drives the mixing barrel 3 to rotate along the inner cavity wall of the housing 2. The rotating mixing barrel 3 drives the second ball 302 to roll along the annular groove 204 to improve the rotating effect of the mixing barrel 3 until the discharge port 301 opened on the outer wall of the mixing barrel 3 communicates with the blanking pipe 201. The adjusting motor 404 stops working. At this time, the bidirectional motor 6 works in reverse, driving the stirring assembly 5 and the moving assembly 7 to work in reverse as well. The moving assembly 7 working in reverse drives the housing 2 to return along the route. The stirred feed is pushed by the second stirring rod 503 and the rake teeth 5031 to be discharged from the discharge port 301 and the blanking pipe 201 and fall into the passing feeding trough 1, completing the laying of the feed.
