Description

Technical Field

[0001] The invention belongs to the technical field of animal husbandry equipment, and in particular is an environmentally friendly cattle breeding feed recovery and reuse device. Background Art

[0002] Protein is an essential nutrient for the human body. People need to consume a lot of protein in their daily lives to ensure good health and balanced nutrition. Beef is a high-protein food that plays an important role in maintaining muscle tissue, bone health and body repair. Beef also contains protein, fat, cholesterol, creatine, minerals and other ingredients, which can supplement minerals, promote muscle growth and repair, provide sufficient energy, and improve blood circulation.

[0003] As people's material living standards continue to improve, the demand for beef is increasing, and the scale of cattle farming is also expanding. However, in order to respond to the advocacy of environmentally friendly life and maximize resource utilization, cattle farming methods and equipment are also constantly improving, but the existing cattle farming equipment generally uses conveyor belt devices to participate in daily feed delivery and feces sewage recovery, reducing the labor cost of daily feeding and improving work efficiency. Few devices are specially used to treat waste feed in cattle farming, and daily waste feed is uniformly treated by centralized composting. It is impossible to observe the proportion of remaining feed, so it is impossible to judge the picky eating of cattle, and it is impossible to accurately adjust the cattle feed ratio and observe the cattle's eating situation to reflect the health of cattle. In addition, cattle are fed hay on a daily basis. Hay can provide nutrition, promote digestion, increase milk fat rate and maintain rumen health. If the hay in the leftovers is not soaked and deteriorated, it can continue to be fed, which can achieve environmentally friendly feeding and ensure the maximum utilization of feed resources.

[0004] Since there is no device to integrate the detection of the proportion of residual feed and the separation of reusable hay in the operation of handling residual feed in cattle farming, it is necessary to propose an environmentally friendly cattle farming feed recovery and reuse device that can detect the proportion of residual feed and separate the reusable hay at the same time. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide an environmentally friendly cattle breeding feed recovery and reuse device, which detects the weight of various types of leftovers through sensors, analyzes the proportion of leftovers through controllers, and separates the leftovers and reusable hay through fans.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an environmentally friendly cattle breeding feed recovery and reuse device, comprising a box body, a box cover movably connected to the top of the box body, the box cover provides a closed condition for fermentation, a screening component for screening and separating leftovers of different particle sizes is provided on the inside of the box body, a detection component for detecting the weight of the screened and separated particles is provided on the screening component, a fermentation component for composting and fermenting the waste leftovers is provided at the bottom of the box body, fan components are respectively provided on the sides of the box body, an oscillation component and a swing component are provided in the box body, the fan component includes a fan cavity, a rotating motor is fixedly connected to the side wall of the fan cavity, the output shaft of the rotating motor passes through the side wall of the fan cavity and is coaxially fixedly connected to the fan blade, and the side of the bottom of the box body is connected to an output component for centrally outputting organic fertilizer after fermentation is completed.

[0007] The principle of the basic solution is: the opening and closing of the box cover provides a closed condition for fermentation, the screening and detection of the screening component and the detection component can obtain the proportion of residual materials, the fan component drives the fan blades through the rotating motor to generate wind force to push and separate the hay with lighter weight and larger volume, and the mutual cooperation between the fan component, the oscillation component and the swing component can more thoroughly achieve the separation of hay and impurities.

[0008] The beneficial effects of the basic scheme are: 1. In some pastures, the leftovers contain a large amount of stems, moldy silage blocks and feed with poor palatability. According to the existing technology, such leftovers should be discarded. If they are not specially treated, these leftovers are prone to produce bacteria that pollute the environment. However, the fermentation component can ferment the leftovers to produce organic fertilizer. Compared with the existing technology, organic fertilizer can be used for farming to increase soil fertility and avoid pollution to the environment. It is more in line with the requirements of environmentally friendly life and promotes the recycling of resources.

[0009] 2. The proportion of each type of leftover feed varies every day. The detection component will collect and count the weight information of various types of particles after screening, and then compare the proportions to see the picky eating and eating habits of cattle. Compared with the existing technology, analyzing the daily leftover feed proportion can more humanely adjust the feed ratio and observe the eating habits of cattle, which is convenient for accurate control of the health status of cattle and reduce the waste of leftover feed.

[0010] 3. The hay in the leftovers can be evaluated for its quality and then fed a second time. The fan assembly can separate and collect it according to its weight. By separating the reusable hay from the non-reusable hay, the discarding of waste can be accurately controlled to avoid unnecessary waste of resources and maximize resource utilization.

[0011] Furthermore, the screening assembly includes a plurality of sieve plates, each of which is provided with a plurality of filter holes, the diameter of the filter holes of the sieve plates decreases from top to bottom, springs are fixedly connected to the four corners of the sieve plates, and the other ends of the springs are fixedly connected to the inner wall of the adjacent box body.

[0012] The beneficial effects of the basic solution are: the filter holes with different diameters on the screen plate can separate the residual particles from large to small, and the spring can vibrate when the residual material hits the screen plate, which assists in screening and reduces the problem of clogging the filter holes.

[0013] Furthermore, the detection component includes a number of sensors corresponding to the sieve plates, the sensors are fixedly connected to the corresponding sieve plates, the outer side wall of the box is fixedly connected with a display and a controller, the sensors are connected to the controller signals, and the controller is connected to the display signals.

[0014] The beneficial effect of the basic solution is that the sensor can detect the weight of the residual material separated by each sieve plate and transmit the signal to the display for real-time display, so that the proportion of particles of different sizes in the residual material can be observed at any time.

[0015] Furthermore, the fermentation component includes a fermentation chamber, a stirring motor is fixedly connected to the bottom wall of the fermentation chamber, the output shaft of the stirring motor extends into the fermentation chamber and is fixedly connected to a plurality of stirring blades, a feeding port is provided on the side wall of the fermentation chamber, a pressure relief valve is provided on the inner side wall of the fermentation chamber, a temperature sensor is fixedly connected in the fermentation chamber, the temperature sensor is connected to the display signal, and the temperature sensor detects the temperature of the fermentation box and displays it in real time through the display.

[0016] The beneficial effects of the basic solution are: the fermentation chamber provides a fermentation environment, the stirring motor drives the stirring rod to drive the stirring blades to mix the upper and lower layers of the fermentation, which helps the fermentation bacteria and the fermentation to contact, promotes fermentation, and also helps the discharge of fermentation gas, preventing the fermentation from settling and agglomerating, and then exhausts the gas through the vent.

[0017] Furthermore, the fan assembly includes a fan cavity, which is connected to the box body. An impurity port is opened on the side wall of the fan cavity close to the box body, and the fan cavity is connected to the fermentation cavity through the impurity port.

[0018] The beneficial effects of the basic scheme are: 1. The forward rotation of the rotating motor can blow the lighter hay to the side away from the fan chamber for collection and processing. The wetted hay is not dry enough and is easy to deteriorate and cannot be fed a second time. The wetted hay becomes heavier and will be retained on the screen plate, thereby achieving the purpose of separating the deteriorated hay.

[0019] 2. Reversing the rotation of the motor can suck the impurities that cannot pass through the sieve plate into the fan chamber, and the impurities that fall into the fan chamber will enter the fermentation chamber through the impurity port for fermentation.

[0020] Furthermore, the rocking assembly includes several fixed plates corresponding to the positions of the sieve plates, the fixed plates are fixedly connected to the side walls of the oscillation chamber, the fixed plates are fixedly connected to fixed rods, the other ends of the fixed rods are rotatably connected to rotating rods, the other ends of the rotating rods are fixedly connected to rotating plates, the fixed plates are fixedly connected to positioning rubber bands, the other ends of the positioning rubber bands are fixedly connected to the rotating plates, the side walls of the rotating rods are fixedly connected to positioning plates, a guide rope is provided on one side of the rotating plate close to the positioning plate, the guide rope is wound around the rotating rod, and the other ends of the guide ropes are fixedly connected to the corresponding sieve plates.

[0021] The beneficial effect of the basic scheme is: when the leftover material is continuously put onto the screen plate, the impact of gravity will pull the guide rope out, causing the rotating disk to rotate, and the rotating disk will pull the positioning rubber band to cause elastic deformation, forming an energy storage process. When the putting is completed and the impact force is reduced, the positioning rubber band will restore its original elastic force to make the rotating disk rotate in the opposite direction, and the guide rope will be rewound around the rotating rod. At this time, the screen plate is pulled by the tension and swings, helping the leftover particles to pass through the screen plate.

[0022] Furthermore, the oscillation assembly includes an oscillation chamber, an oscillation motor is fixedly connected to the top of the oscillation chamber, a cam rod is coaxially fixedly connected to the output shaft of the oscillation motor, four cams corresponding to the screen plate are fixedly connected to the cam rod, and a hay opening is opened at the bottom of the oscillation chamber away from the box body.

[0023] The beneficial effects of the basic solution are: the hay blown into the oscillation chamber by the fan assembly is collected and processed through the hay port, and the cam is driven to rotate by the cam rod driven by the oscillation motor, continuously hitting the corresponding screen plate, causing the screen plate to continuously perform lateral reciprocating motion, assisting the screen plate to screen out the remaining material and reducing the problem of clogging of the screen plate filter holes.

[0024] Furthermore, the output component includes an output port, the output port is connected to an output pipe, a valve is provided at the connection between the output port and the output pipe, and the output port is arranged on the side wall of the fermentation chamber.

[0025] The beneficial effect of the basic scheme is that the organic fertilizer after fermentation needs to be discharged, and the valve and output pipe can make the organic fertilizer discharged more thoroughly and centrally, reducing the pollution to the surrounding environment.

[0026] Furthermore, the bottom of the fan cavity and the bottom of the oscillation cavity are both inclined surfaces.

[0027] The beneficial effect of the basic solution is that the fan assembly collects impurities and licorice to the bottom of the fan chamber and the bottom of the oscillation chamber through forward and reverse rotation respectively. However, impurities and hay are prone to accumulate at the bottom of the chamber. If they are not cleaned in time for a long time, they are prone to corruption. Setting the bottom of the chamber as an inclined surface can make the impurities and licorice slide toward the mouth, reducing accumulation and clogging of the outlet.

[0028] Furthermore, the area of ​​the sieve plate increases from top to bottom.

[0029] The beneficial effect of the basic solution is: as the residual material is continuously put into the screen plate, the screen plate shakes to screen the residual material. During the shaking process, there will be overflow due to the large amount of residual material on the upper layer. The larger area of ​​the screen plate below will catch the overflow and continue to screen, ensuring that all residual material particles are screened and separated.

The output component includes an output port, and the output port is connected to an output pipe 28. A valve 29 is provided at the connection between the output port and the output pipe 28. The output port is arranged on the side wall of the fermentation cavity, which can control the output of organic fertilizer in real time to prevent pollution.A vibration component and a swing component are also provided in the box. The oscillation component includes an oscillation chamber 15. An oscillation motor 16 is fixedly connected to the top of the oscillation chamber 15 by bolts. A cam rod 17 is coaxially welded to the output shaft of the oscillation motor 16. Four cams 18 corresponding to the sieve plate 3 are welded on the cam rod 17. A hay port 19 is opened at the bottom of the bottom of the oscillation chamber 15 away from the box 1. The swing component includes a plurality of fixed plates 20 corresponding to the position of the sieve plate 3. The fixed plates are welded and fixed to the side walls of the oscillation chamber. Fixed rods 21 are welded to the fixed plates 20. The other ends of the fixed rods 21 are rotatably connected to rotating rods 22. The other ends of the rotating rods 22 are welded to rotating plates 23. Positioning rubber bands 25 are bonded to the fixed plates 20. The other ends of the positioning rubber bands 25 are bonded to the positioning plates 24. Positioning plates 24 are welded to the side walls of the rotating rods 22. A guide rope 26 is provided on the side of the rotating plate 23 close to the positioning plate 24. The guide rope 26 is wound around the rotating rod 22, and the other ends of the guide ropes 26 are bonded to the corresponding sieve plate 3.

[0038] The specific implementation process is as follows: when using the device, open the box cover 2, put the leftover material into the box body 1, and finally close the box cover 2. Under the action of gravity, the particles in the leftover material that are larger than the sieve holes are retained on the corresponding sieve plate 3, and those that are smaller than the sieve holes fall onto the next sieve plate 3 for the next screening, until they pass through all the sieve plates 3 and enter the fermentation chamber 7. During this process, the leftover material hits the sieve plate 3, driving the spring 5 to stretch, and finally the spring 5 rebounds, driving the sieve plate 3 to shake. Due to inertia, the leftover material on the surface of the sieve plate 3 can temporarily break away from the sieve plate 3, thereby reducing the probability of the leftover material clogging the sieve holes.

[0039] During the up and down swinging of the sieve plate 3, the sieve plate 3 drives the guide rope 26 to gradually separate from the rotating rod 22. During this process, the rotating rod 22 rotates, thereby driving the rotating disk 23 to rotate, and the rotating disk 23 drives one end of the rubber band to move, thereby causing the rubber band to deform, forming an energy storage process. When the feeding is completed, the impact force of the residual material on the sieve plate 3 gradually decreases. When the force applied by the sieve plate 3 on the guide rope 26 can no longer continue to deform the rubber band, the rubber band rebounds, driving the rotating disk 23 to reset, thereby driving the rotating rod 22 to reset, and rewinding the guide rope 26 around the rotating rod 22. The guide rope 26 drives the sieve plate 3 to move, thereby causing the sieve plate 3 to shake, assisting the residual material particles to pass through the sieve holes. The design of the swing component makes full use of the impact force of the residual material on the sieve plate 3 when it is put in, and prolongs the shaking time of the sieve plate 3. No power components are required in this process, effectively saving energy consumption.

[0040] At the same time, the sensor continuously collects weight information on the sieve plate 3. After the weight information becomes constant, the sensor calculates the proportion of particles of various sizes in the remaining material based on the weight of the remaining material on each sieve, so as to observe the eating conditions of the cattle and determine whether the cattle are picky eaters, so as to accurately control the health status of the cattle.

[0041] During this process, the oscillation motor is started, and the output shaft of the oscillation motor drives the cam rod 17 to rotate, and the cam rod 17 drives the cam 18 to rotate, continuously hitting the adjacent screens, further assisting the residual material to pass through the corresponding screen holes, further reducing the probability of residual material particles blocking the holes, and reducing the possibility of large particles blocking the holes, making it impossible for small particles on the upper part to pass through the screen holes and enter the screen below, thereby causing errors in particle ratio calculation.

[0042] During the shaking of the sieve plate 3, the rotating motor 12 is started. Since the hay in the residual material is light in weight and not easy to rot and deteriorate, it can be fed for secondary feeding. The forward rotation of the rotating motor 12 can blow the light hay. Due to inertia, the hay briefly separates from the sieve plate 3 during the shaking of the sieve plate 3. At this time, the rotating fan blows the hay into the oscillation chamber 15 to facilitate the subsequent secondary feeding. Then the rotating motor 12 is reversed. Compared with the forward rotation, the rotation speed is increased, which makes the suction force greater, so that the heavier impurities that cannot pass through the sieve plate 3 can be sucked into the fan chamber 11, and the impurities that fall into the fan chamber 11 will enter the fermentation chamber 7 through the impurity port 14 for fermentation treatment. The forward and reverse rotation of the rotating motor 12 can realize the centralized collection of hay and impurities, which simplifies the device structure and reduces energy consumption.

[0043] The leftover material entering the fermentation chamber 7 can be fermented in the fermentation chamber 7. At this time, calcium cyanamide is kneaded into the fermentation chamber 7 through the feeding port 30 to promote fermentation. The stirring motor 8 drives the stirring rod 27 to drive the stirring blade 9 to mix the upper and lower layers of the fermented material, help the fermentation bacteria and the fermented material to contact and promote the contact of calcium cyanamide with the fermented material. While promoting fermentation, it also helps the discharge of fermentation gas to prevent the fermented material from depositing and agglomerating. In order to ensure that the compost is evenly decomposed inside and outside, it is turned over every three or four weeks, and then the pressure relief valve is used for exhaust treatment. After about three months, it can be used. During the fermentation process, the temperature in the fermentation chamber 7 is detected in real time and displayed through the display 6. Generally, the compost fermentation temperature is about 50 degrees Celsius. When the temperature of the fermentation chamber 7 is too low, a film covering insulation method can be used for heating care. When the temperature is too high, the stirring motor 8 can be started for stirring and heat dissipation to ensure the normal temperature of the fermentation. After fermentation, organic fertilizer is obtained, and resource utilization is maximized and environmental pollution is reduced.

[0044] After the fermentation is completed, the valve 29 is opened to discharge the fertilizer through the output pipe 28 to reduce the pollution to the surrounding environment.

[0045] Embodiment 2, basically as attached Figure 2 As shown:

[0046] The difference from the above embodiment is that the bottom of the fan chamber 11 and the bottom of the oscillation chamber 15 are both inclined surfaces.

[0047] The specific implementation process is as follows: the discarded impurities and wet hay carry a certain amount of moisture. The fan assembly collects the impurities and licorice to the bottom of the fan chamber 11 and the bottom of the oscillation chamber 15 through forward and reverse rotation. However, the impurities and hay are easy to accumulate at the bottom of the chamber. If they are not cleaned in time for a long time, they are easy to corrupt. Setting the bottom of the chamber as an inclined surface can make the impurities and licorice slide toward the mouth, reducing accumulation and clogging of the outlet.

[0048] Embodiment 3 is basically as shown in Appendix 2:

[0049] The difference from the above embodiment is that the area of ​​the sieve plate 3 increases from top to bottom.

[0050] The specific implementation process is as follows: as the leftovers are continuously put into the screen plate 3, the screen plate 3 is shaken to screen the leftovers. During the shaking process, there will be overflow due to the large amount of leftovers on the upper layer. The lower screen plate 3 with a larger area will receive the overflow and continue to screen, ensuring that all the leftover particles are screened and separated, which can more accurately reflect the proportion of leftovers and observe the health of the cattle.
