Description

Technical Field

[0001] This invention relates to the field of porridge making machine technology, and particularly to a mixing and dust-reducing porridge making machine. Background Technology

[0002] Existing porridge feeders primarily use a feed hopper and water pipes above the trough to separately deliver water and feed into the trough, allowing pigs to root and mix them during feeding. However, this mixing method has the following problems: water and feed can only be delivered separately to the trough, making it impossible to directly produce porridge-like feed, resulting in poor palatability for pigs and the generation of dust; the water pipe has only one outlet with a large flow rate, leading to uneven water distribution and uneven mixing of water and feed. These problems can result in low immunity in pigs, a high risk of disease, and a high mortality rate. Summary of the Invention

[0003] The purpose of this invention is to provide a mixing and dust-reducing porridge feed machine, which aims to solve the technical problems of existing porridge feed machines that can only put water and feed into the trough separately, cannot directly produce porridge-like feed, have poor palatability for pigs, and also generate some dust; the water pipe has only one outlet and the flow rate is large, resulting in uneven water output and uneven mixing of water and feed.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] The mixing and dust-reducing porridge machine includes a hopper and a feeding trough located below the hopper. It also includes a water sprayer and a mixer located between the hopper and the feeding trough. The water sprayer has a water storage chamber and an inlet pipe connected to the water storage chamber. The bottom of the water sprayer has multiple outlets connected to the water storage chamber. The mixer is located below the water sprayer and has an upward-opening mixing chamber. The mixing chamber is equipped with a stirrer driven by a drive mechanism. The side wall of the mixer has multiple outlets connected to the mixing chamber.

[0006] With the above structure, a porridge-like feed can be directly dispensed by a mixer, which is palatable to pigs. Water is sprayed from multiple outlets, which can absorb dust that falls during the feed process. Water is dispensed from multiple outlets at the same time, ensuring uniform water distribution and achieving uniform mixing of the feed.

[0007] Preferably, the water storage chamber has a ring-shaped cross-section and a conical longitudinal section, with the width of the longitudinal section gradually narrowing downwards. The conical shape of the water storage chamber results in a gradually decreasing cross-sectional area and a gradually increasing water pressure, giving the water flow a certain speed and impact force. This allows for better absorption of dust generated during feed descent, and the water jet from the outlet can wash away feed adhering to the mixer and feed trough.

[0008] Preferably, the longitudinal section of the water outlet is tapered, and the diameter of the water outlet gradually narrows downwards. The tapered shape of the water outlet causes the water pressure to gradually increase as the water flows through the outlet, enhancing the dust suction and rinsing effects of the water flow.

[0009] Preferably, the agitator includes a mounting block and a plurality of agitating rods uniformly fixed to the outer side of the mounting block circumferentially. The agitator, including the mounting block and agitating rods, facilitates installation, improves mixing efficiency, and ensures more uniform mixing of water and materials.

[0010] Preferably, the mixing and dust-reducing porridge feeder also includes several sensing mechanisms. Each sensing mechanism includes a sensing frame, a trigger plate mounted on the sensing frame, a liquid level probe hinged to the sensing frame and capable of swinging to contact the trigger plate, and a first elastic mechanism for driving the liquid level probe to reset. The liquid level probe extends into the feeding trough. The liquid level probe detects the liquid level of the porridge in the feeding trough. When the liquid level reaches the target level, the detection circuit is activated. When pigs eat, they nudge the liquid level probe, causing it to swing and contact the trigger plate, generating a trigger signal. The sensing mechanism simultaneously performs liquid level sensing and trigger sensing. Feed is supplied to the feeding trough when the pig nudges the probe to generate a trigger signal and the porridge level reaches below the liquid level probe. Feeding stops when the porridge level reaches the liquid level probe. This avoids overfeeding due to misjudgment, saves feed, and improves stability.

[0011] Preferably, the bottom of the sensing frame is provided with a limiting plate, and a limiting through hole is formed on the limiting plate. A trigger plate is set above the limiting plate, and a trigger through hole is formed on the trigger plate. The first elastic mechanism is an elastic sleeve covering the trigger through hole, and a sleeve hole is formed on the top of the elastic sleeve for the liquid level probe to pass through. The swing position of the liquid level probe is limited by the limiting through hole, and the liquid level probe is reset after swinging by the elastic sleeve. The liquid level probe contacts the trigger plate, generating a trigger sensing to identify pigs eating feed.

[0012] Preferably, the diameter of the trigger hole is larger than the diameter of the level probe, and the diameter of the limiting through hole is larger than the diameter of the trigger hole. This structure avoids interference when the level probe swings.

[0013] Preferably, the upper end of the level probe is provided with a spherical body, and the upper end of the sensing frame is provided with a spherical hole that matches the spherical body. Through the cooperation of the spherical body and the spherical hole, the level probe can swing omnidirectionally through the spherical hole, thus enabling the level probe and the sensing frame to be hinged.

[0014] Preferably, the hopper includes a cylinder and a top cover. The top cover has an inclined mounting part, and the controller is inclinedly embedded in the mounting part. The controller controls the operation of the drive mechanism. The controller is inclinedly embedded in the top cover, which provides good overall protection, facilitates personnel viewing and operation, and also protects the sealing area between the top cover and the cylinder, increasing waterproof safety.

[0015] Preferably, the upper end of the water storage chamber is connected to a sliding chamber, the diameter of which is the same as the upper diameter of the water storage chamber. A pressure plate is slidably installed inside the sliding chamber. Above the pressure plate is a second elastic mechanism located inside the sliding chamber. Multiple vertically arranged insert rods are fixedly connected to the bottom of the pressure plate, each corresponding to a water outlet. The insert rods can be inserted into the water outlets. A scraper is rotatably installed at the lower end of each insert rod, and multiple circumferentially arranged blades are fixedly connected to the scraper. When water is supplied to the water storage chamber through the inlet pipe, the water presses down on the pressure plate, causing it to rise and the insert rods to move out of the water outlets. When the water supply stops, the pressure plate moves downward under the action of the elastic mechanism and its own gravity, squeezing the water in the water storage chamber downwards. The insert rods are then inserted into the water outlets to expel scale from the outlets. The scraper and blades rotate under the impact of the water, cleaning the scale on the side walls of the water outlets and removing any porridge that splashes into the outlets, preventing the outlets from becoming clogged with scale after prolonged use.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are:

[0017] This invention, by setting up a mixer, can directly produce porridge-like material with good palatability for pigs; water is sprayed out from multiple outlets, which can absorb dust that falls during the feed process, and the water is discharged from multiple outlets at the same time, so as to achieve uniform mixing of feed.

Detailed Implementation

[0029] The invention will now be further described with reference to the accompanying drawings.

[0030] The orientations mentioned in this specification are based on the orientation of the mixing and dust-reducing porridge machine of this invention during normal operation, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, the mixing and dust-reducing porridge machine includes a hopper 1 and a feeding trough 2 located below the hopper 1. It also includes a water sprayer 4 and a mixer 3 located between the hopper 1 and the feeding trough 2. The water sprayer 4 has a water storage chamber 40 and an inlet pipe 41 connecting to the water storage chamber 40. Multiple outlets 42 connecting to the water storage chamber 40 are located at the bottom of the water sprayer 4. The mixer 3 is located below the water sprayer 4 and has an upward-opening mixing chamber 30. A stirrer 31 driven by a drive mechanism is installed in the mixing chamber 30. Multiple outlets 32 connecting to the mixing chamber 30 are located on the side wall of the mixer 3. Preferably, the mixing chamber 30 is cylindrical, the outlets 42 are circular holes, and the outlets 32 are arranged in two layers, with a rectangular shape. The multiple outlets 32 are evenly distributed along the circumference of the mixer 3.

[0033] The water sprayer 4 is located inside the feed inlet 15 at the bottom of the hopper 1, and there is a feeding gap between the outer wall of the water sprayer 4 and the inner wall of the feed inlet 15. The upper end of the mixer 3 is closed and connected to the lower end of the feed inlet 15. The mixer 3 is installed on the feed trough 2 or the hopper 1. The rotating shaft 10 is rotatably installed inside the hopper 1, and the lower end of the rotating shaft 10 passes through the water sprayer 4 and the mixer 3, and the rotating shaft 10 is rotatably connected to the water sprayer 4 and the mixer 3. Above the water sprayer 4 is a lever 11 fitted on the rotating shaft 10. The lever 11 rotates with the rotating shaft 10 to push the feed on the water sprayer 4 between the water sprayer 4 and the feed inlet 15, so that the feed in the hopper 1 falls into the mixer 3. The agitator 31 is fitted on the rotating shaft 10. The drive mechanism can be a motor, with the motor's output shaft connected to the upper end of the rotating shaft 10 via a coupling. Various drive mechanisms exist, but the drive mechanism is a standard structure for porridge makers and will not be elaborated upon here. The drive mechanism drives the rotating shaft 10 to rotate, thereby driving the agitator 31 to rotate.

[0034] In use, the feed in hopper 1 falls into the mixing chamber 30 of the mixer. Water entering the water storage chamber 40 through the water inlet pipe 41 is sprayed out from multiple outlets 42, spraying the feed in the mixing chamber 30 from multiple directions. The drive mechanism drives the agitator 31 to rotate, thoroughly mixing the feed and the water sprayed in the mixing chamber 30 into a porridge-like feed. The rotation of the agitator 31 causes the porridge-like feed to overflow into the feed trough 2 through the discharge outlet 32. This invention, by setting up the mixer 3, can directly discharge porridge-like material, which has good palatability for pigs; the water sprayed from multiple outlets 42 can absorb the dust during the feed falling process, and the simultaneous discharge of water from multiple outlets ensures uniform water output and achieves uniform mixing of the feed.

[0035] The agitator 31 includes a mounting block 310 and multiple agitator rods 311 that are uniformly fixed to the outer side of the mounting block 310 circumferentially. The mounting block 310 is fitted onto the rotating shaft 10 and rotates with the rotating shaft 10. The agitator 31, including the mounting block 310 and the agitator rods 311, facilitates the installation of the agitator 31, improves the mixing efficiency, and makes the water and materials mix more evenly.

[0036] As a preferred embodiment, the water storage chamber 40 has an annular cross-section and a conical longitudinal section, with the width of the longitudinal section gradually narrowing downwards. The conical shape of the water storage chamber 40 results in a gradually decreasing cross-sectional area and a gradually increasing water pressure, giving the water flow a certain speed and impact force. This allows for better absorption of dust generated during the feed's descent, and the water jet from the outlet 42 can wash away feed adhering to the mixer 3 and the feed trough 2.

[0037] Furthermore, the longitudinal section of the outlet 42 is tapered, and the diameter of the outlet 42 gradually narrows downwards. The tapered shape of the outlet 42 causes the water pressure to gradually increase as it flows through the outlet 42, enhancing the dust suction and rinsing effects of the water flow.

[0038] To save costs, the water sprayer 4 includes an annular housing 43 with a tapered longitudinal section. The width of the longitudinal section of the annular housing 43 gradually narrows downwards. The water storage chamber 40 and the water outlet 42 are located on the annular housing 43. The annular housing 43 adopts the above structure, which can save materials, facilitate processing, and reduce costs.

[0039] The annular housing 43 has an opening at the top, and the water sprayer 4 also includes a cover plate 44 that closes the upper end of the annular housing 43. The cover plate 44 is installed on the hopper 1. Both the inner and outer rings of the annular housing 43 have annular grooves at their upper ends, and sealing rings are installed in these grooves. The cover plate 44 and the annular housing 43 are fastened together with bolts. The water sprayer 4 is assembled from the cover plate 44 and the annular housing 43, which facilitates the processing of the water sprayer 4 and further reduces costs.

[0040] In a preferred embodiment, the cross-sectional width of the water storage chamber 40 is greater than the cross-sectional width of the outlet 42. The upper end of the outlet 42 is connected to the lower end of the water storage chamber 40 through a semi-circular hole. The greater cross-sectional width of the water storage chamber 40 compared to the outlet 42 further increases the flow rate of water from the outlet 42, better absorbing dust during the feed falling process and rinsing feed adhering to the mixer 3 and the feed trough 2.

[0041] In a preferred embodiment, the annular shell 43 is coaxially arranged with the mixing chamber 30, and multiple water outlets 42 are evenly distributed along the circumference of the annular shell 43. The water outlets 42 are arranged as a group, and the multiple water outlets 42 evenly distributed along the circumference of the annular shell 43 can improve the uniformity of water output and the uniformity of feed mixing.

[0042] As a preferred embodiment, the bottom of the annular shell 43 has an upward-facing process groove 45 located between two adjacent outlets 42. Preferably, the process groove 45 is elongated. The process groove 45 reduces the bottom wall thickness of the annular shell 43, avoiding the problem of shrinkage in the injection mold.

[0043] In a preferred embodiment, a control valve and a flow meter are installed on the inlet pipe 41. The control valve can be a solenoid valve. The control valve is used to control the opening and closing of the inlet pipe 41, and the flow meter is used to monitor the water flow rate.

[0044] Example 2:

[0045] like Figures 1 to 6As shown, as a further improvement to Embodiment 1, the mixing and dust-reducing porridge machine also includes several sensing mechanisms 5, which are located outside the hopper 1. Each sensing mechanism 5 includes a sensing frame 50, a trigger plate 51 mounted on the sensing frame 50, a liquid level probe 52 hinged to the sensing frame 50 and capable of swinging to contact the trigger plate 51, and a first elastic mechanism for driving the liquid level probe 52 to reset. The liquid level probe 52 extends into the feeding trough 2.

[0046] The level probe 52 detects the level of porridge in the feed trough 2. When the porridge level reaches the target level, the detection circuit is activated. When pigs eat, they nudge the level probe 52, causing it to swing and contact the trigger plate 51, generating a trigger signal. The sensing mechanism 5 combines level sensing and trigger sensing. Feeding begins when the pig nudges the probe, generating the trigger signal, and the porridge level reaches below the level probe 52. Feeding stops when the porridge level reaches the level probe 52. This avoids overfeeding due to misjudgment, saves feed, and improves stability.

[0047] The conduction structure of the detection circuit of the liquid level probe 52 is a conventional structure. The two ends of the ground wire are connected to the controller 14 and the feed tank 2 respectively, and the two ends of the liquid level probe wire are connected to the controller 14 and the liquid level probe 52 respectively.

[0048] In a preferred embodiment, the porridge feeder has two interlocking partitions on both sides. Two sensing mechanisms 5 are provided, and the liquid level probes 52 of the two sensing mechanisms 5 form a conductive loop when the liquid level is reached. The probe lines of the two liquid level probes are connected to the controller. The two sensing mechanisms 5 are respectively located in the chambers where the two partitions interlock, with the liquid level probes 52 extending out of the chambers and into the feed trough 2. When the liquid level probes 53 contact the liquid level probes 52, they form their own conductive loops, without connection to the overall frame; this solves the problem of probe misalignment and ensures high system stability.

[0049] With continuous water and feed supply, the porridge level in feed trough 2 gradually increases. When the level touches the level probe 52, the level circuit is activated, transmitting a closed signal to the controller 14. The controller 14 determines that feed trough 2 is full based on the closed signal. When the level probe 52 touches the trigger piece 51, the trigger circuit is activated, transmitting a trigger signal to the controller 14. When the pig arching rod generates a trigger signal and the porridge level reaches below the level probe 52, the controller 14 drives the drive mechanism to operate. The rotating shaft 10 rotates, causing the paddle block 11 to rotate, feeding downwards, and the agitator 31 rotates to mix the porridge. When the porridge level reaches the level probe 52, the drive mechanism stops operating, the paddle block 11 stops rotating, and feeding and mixing cease.

[0050] In a preferred embodiment, the bottom of the sensing frame 50 is provided with a limiting plate 53, and a limiting through hole 54 is provided on the limiting plate 53. A trigger plate 51 is disposed above the limiting plate 53, and a trigger through hole 55 is provided on the trigger plate 51. The first elastic mechanism is an elastic sleeve 56 covering the trigger through hole 55, and a sleeve hole 57 for the liquid level probe 52 to pass through is provided on the top of the elastic sleeve 56. The swing position of the liquid level probe 52 is limited by the limiting through hole 54, and the liquid level probe 52 is reset by the elastic sleeve 56 after swinging. The liquid level probe 52 contacts the trigger plate 51 to generate a trigger sensing and identify that the pig is eating feed.

[0051] The trigger piece 51 has a boss 59, and the elastic sleeve 56 is installed on the boss 59.

[0052] The porridge feeder has two interlocking partitions on both sides. There are two sensing mechanisms 5, which are respectively set in the chambers where the two partitions are interlocked. The liquid level probe 52 extends out of the chamber and into the feed trough 2.

[0053] The elastic sleeve 56 is made of rubber and polyurethane. When the pig moves the liquid level probe 52 by rubbing against it while eating, the elastic sleeve 56 deforms. When the pig stops moving the liquid level probe 52, the elastic sleeve 56 returns to its original position, so that the liquid level probe 52 returns to its vertical position.

[0054] The liquid level probe 52 has a spherical body 520 at its upper end, and the sensing frame 50 has a spherical hole 500 at its upper end that matches the spherical body 520. The top of the sensing frame 50 has a mounting bracket 501, which has a spherical hole 500 for accommodating the spherical body 520 and a cylindrical mounting hole 502 for accommodating the upper end of the liquid level probe 52. There is a gap between the spherical hole 500 and the spherical body 520, and a gap between the liquid level probe 52 and the cylindrical mounting hole 502, allowing the liquid level probe 52 to swing slightly around the spherical hole 500 without interference from the sensing frame 50. Through the cooperation of the spherical body 520 and the spherical hole 500, the liquid level probe 52 can swing omnidirectionally around the spherical hole 500, thus achieving a hinged connection between the liquid level probe 52 and the sensing frame 50.

[0055] The diameter of the trigger hole is larger than the diameter of the level probe 52, and the diameter of the limiting through hole 54 is larger than the diameter of the trigger hole. This structure prevents interference when the level probe 52 swings.

[0056] In a preferred embodiment, the level probe 52 is fitted with guide blocks 58 spaced vertically apart, and a limiting plate 53 is disposed between the two guide blocks 58. The guide blocks 58 can move on the limiting plate 53 as the level probe 52 swings. The guide blocks 58 are made of rubber and polyurethane, and deform to adapt to the swing angle when the level probe 52 swings. By using guide blocks 58, wear on the level probe 52 can be avoided, thus improving its service life.

[0057] Example 3:

[0058] like Figure 1 and Figure 7 As shown, as a further improvement to Embodiment 1, the hopper 1 includes a cylinder 12 and a top cover 13. The top cover 13 is provided with an inclined mounting part 16, and the controller 14 is inclinedly embedded in the mounting part 16. The controller 14 controls the operation of the drive mechanism. The controller 14 is inclinedly embedded in the top cover 13, which provides good overall protection, facilitates personnel viewing and operation, and can also protect the sealing area between the top cover 13 and the cylinder 12, increasing waterproof safety.

[0059] The controller 14 features a transparent solid ABS membrane with no cavities. The buttons and lights have built-in rubber pads and are made using an in-mold injection molding process, which can withstand high-pressure washing with a pressure gun of over 180kg. The upper and lower shells of the controller 14 have multiple reinforcing ribs to increase overall strength, and the four fixing points use M8 plastic bolts with high locking force.

[0060] Example 4:

[0061] like Figure 8 and Figure 9 As shown, as a further improvement to Embodiment 1, the upper end of the water storage cavity 40 is connected to a sliding cavity 6. The diameter of the sliding cavity 6 is the same as the diameter of the upper end of the water storage cavity 40. A pressure plate 7 is slidably installed inside the sliding cavity 6. A second elastic mechanism is provided above the pressure plate 7 and located inside the sliding cavity 6. A plurality of vertically arranged insert rods 70 are fixedly connected to the bottom of the pressure plate 7. The insert rods 70 are arranged one-to-one with the water outlets 42 and can be inserted into the water outlets 42. A scraper block 71 is rotatably installed at the lower end of the insert rod 70. A plurality of circumferentially arranged blades 72 are fixedly connected to the scraper block 71. The sliding cavity 6 is opened on the annular shell 43. Preferably, there are four blades 72.

[0062] When the inlet pipe 41 supplies water to the water storage chamber 40, the water presses the pressure plate 7 upward, causing the pressure plate 7 to move upward and the insertion rod 70 to move out of the outlet 42. When the water supply stops, the pressure plate 7 moves downward under the action of the elastic mechanism and its own weight, squeezing the water in the water storage chamber 40 downward, and the insertion rod 70 is inserted into the outlet 42 to squeeze out the scale at the outlet 42. The scraper 71 and blade 72 rotate under the impact of the water to clean the scale on the side wall of the outlet 42 and the porridge that splashes into the outlet 42, preventing the outlet 42 from being blocked by scale after long-term use.

[0063] The sliding cavity 6 has a cylindrical longitudinal section, and its diameter is equal to the diameter of the flared end of the water storage cavity 40. Sealing rings are installed on both the outer and inner sides of the pressure plate 7. The elastic mechanism is a compression spring 73 installed within the sliding cavity 6.

[0064] Two symmetrically arranged guide rods 46 are fixed to the cover plate 44. The lower end of the guide rods 46 is inserted into the bottom of the annular shell 43. The guide rods 46 are positioned to avoid the water outlets 42 and are located between two adjacent water outlets 42. A guide hole 47 is provided on the pressure plate 7, through which the guide rods 46 pass. The pressure plate 7 moves up and down along the two guide rods 46, which can prevent the pressure plate 7 from rotating in the circumferential direction.

[0065] Example 5:

[0066] like Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that the annular shell 43 is provided with multiple water outlet pipes 8 arranged around the edges of the inner and outer rings. The upper and lower ends of the water outlet pipes 8 pass through the bottom of the annular shell 43, and the water outlet 42 is located on the water outlet pipes 8. The arrangement of the water outlet pipes 8 facilitates the processing of the annular shell 43 and increases the water storage volume of the water storage cavity 40. The water outlet pipes 8 are arranged in two sets: one set is evenly arranged around the inner ring of the annular shell 43, and the other set is evenly arranged around the outer ring of the annular shell 43. In this embodiment, the wall thickness of the annular shell 43 is uniform, and it is not necessary to reserve a large thickness dimension at the bottom for opening the water outlet 42. Therefore, it is not necessary to reduce the unevenness of the wall thickness by opening a process groove.

[0067] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
