Description

Technical Field

[0001] This utility model relates to the field of feed mixing technology, specifically to a temperature detection device for a premixed feed mixing silo. Background Technology

[0002] Temperature monitoring during feed mixing allows for timely and effective detection of feed temperature during mixing, preventing high temperatures from causing oxidation and decomposition of nutrients such as fats and vitamins. This maintains the nutritional value and palatability of the feed, ensures stable feed quality, and improves farming efficiency.

[0003] A search revealed that patent CN 222250763 U discloses a pig feed fermentation device with a heating and dehumidification mechanism, including a fermentation tank, a mixing component, a stirring component, an electric heating ring, and a temperature controller. The device is powered by a motor that drives an auger assembly and a drive gear to rotate. The rotating spiral blades on the auger assembly cause the feed inside to tumble up and down. The drive gear meshes with the driven gears on both sides, causing the two sets of driven gears to rotate together on the bearings, thereby rotating the main shaft and stirring frame at the bottom.

[0004] However, the above-mentioned device still has the following problems: the temperature sensing unit is located on the tank wall, which makes the monitoring of the temperature inside the fermentation tank, especially the center temperature, inaccurate and not conducive to the temperature control of the feed inside the tank. Utility Model Content

[0005] To address the problem of inaccurate temperature detection in the central area due to the temperature sensing unit being located on the tank wall in the existing technology, this utility model provides a premixed feed mixing silo temperature detection device to solve the problem of feed temperature detection in the central area of ​​the tank.

[0006] The technical solution adopted by this utility model to solve its technical problem is: This utility model proposes a temperature detection device for a premixed material mixing silo, including a tank body, a controller connected externally to the tank body, a stirring rod rotatably connected to the tank body, a motor rotatably connected to the stirring rod, the motor being fixed above the tank body, a first sensor fixed in a suitable area outside the tank body, a gap being provided between the lower end of the stirring rod and the tank body, a second sensor being slidably connected to the lower end of the stirring rod, the second sensor being electrically connected to the controller, and the second sensor being able to extend out of the stirring rod when the stirring rod stops rotating.

[0007] Preferably, the lower end of the stirring rod is fixedly connected to a fixed base, the fixed base is fixed with at least two sets of guide rods, the guide rods are slidably connected to a counterweight slider through a first spring, and the counterweight slider is fixedly connected to the second sensor.

[0008] Preferably, the motor is rotatably connected to a drive wheel, and a driven wheel is fixed at a suitable position on the circumferential surface of the upper end of the stirring rod, with the drive wheel cooperating with the driven wheel.

[0009] Preferably, the lower end face of the drive wheel is connected by a tension spring to a wedge-shaped slider that can only slide horizontally. At least two sets of the wedge-shaped sliders are evenly distributed on the drive wheel, and the wedge-shaped sliders can be moved away from the center of the drive wheel when the drive wheel rotates.

[0010] Preferably, the tank body is slidably connected to a pressure ring via a second spring. The pressure ring can only slide up and down relative to the tank body. The pressure ring is coaxial with the drive wheel. When the wedge-shaped slider cooperates with the pressure ring, the pressure ring slides downward.

[0011] Preferably, a first conductive block is fixed at a suitable position on the pressure ring, and a second conductive block is fixed at a suitable position on the tank. The first conductive block and the second conductive block cooperate to be electrically connected to the second sensor. When the pressure ring slides downward, the first conductive block and the second conductive block can be separated.

[0012] Preferably, the wedge-shaped slider is provided with a vertical surface, which can cooperate with the inner circumferential surface of the pressure ring.

[0013] Preferably, the pressure ring is fixed with a bearing, the vertical surface is fixed with an anti-slip layer, and the inner circumferential surface of the bearing can cooperate with the anti-slip layer of the vertical surface.

[0014] Preferably, a magnet is fixed to the vertical surface, and the magnet is able to attract the inner circumferential surface of the bearing.

[0015] Preferably, the upper end of the stirring rod extends out of the tank body, and an electric slip ring is rotatably connected to the top of the stirring rod. The fixed end of the electric slip ring is fixedly connected to the tank body, the electric slip ring is electrically connected to the controller, and the second sensor is electrically connected to the electric slip ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The stirring rod is connected to the detachable fixed base. The counterweight slider is slidably connected inside the fixed base. The counterweight slider is fixedly connected to the second sensor. The counterweight slider is also equipped with a matching first spring, which enables the second sensor to retract under the centrifugal force of the counterweight slider when the stirring rod rotates. When the stirring rod stops rotating, the second sensor extends to measure the temperature, thus realizing the temperature measurement of the central area of ​​the tank.

[0017] 2. A wedge-shaped slider is horizontally connected to the end face of the drive wheel, and a pressure ring that slides up and down is connected to the tank body. The pressure ring and the tank body are equipped with a first conductive block and a second conductive block that cooperate with each other. Under the action of centrifugal force of the drive wheel rotation, the wedge-shaped slider cooperates with the pressure ring, causing the pressure ring to slide downward, thereby separating the first conductive block and the second conductive block, and de-energizing the second sensor. This prevents the second sensor from working when the tank is being stirred, thus avoiding economic losses caused by inaccurate temperature detection.

[0018] 3. By setting magnets and anti-slip layers on the vertical surface of the wedge slider and setting bearings on the pressure ring, the rotational resistance of the wedge slider when the drive wheel rotates can be reduced, preventing the wedge slider from slipping relative to the pressure ring and avoiding damage to the device.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1: like Figure 1 - Figure 2 As shown in the figure, this embodiment proposes a premixed feed mixing bin temperature detection device, including a tank 1. A sealing block 2 is detachably connected to the bottom of the tank 1. When the sealing block 2 is opened, the mixed feed in the tank 1 can be released. A controller 6 is connected to the outside of the tank 1. A stirring rod 4 is rotatably connected to the tank 1. The upper end of the stirring rod 4 is located outside the tank 1, and the lower end of the stirring rod 4 extends into the tank 1. Several sets of crossbars are evenly distributed on the stirring rod 4 for uniform stirring of the feed in the tank 1. A motor 7 is fixedly connected to the top of the tank 1. A drive wheel 8 is rotatably connected to the motor 7. A passive wheel 10 is fixed at a suitable position on the circumferential surface of the upper end of the stirring rod 4. The drive wheel 8 and the passive wheel 10 cooperate to achieve smooth transmission. A first sensor 5 is fixed in a suitable area outside the tank 1. The motor 7 and the first sensor 5 are electrically connected to the controller 6.

[0023] Specifically, the first sensor 5 measures the temperature of tank 1 in real time to monitor the stirring of feed in tank 1 throughout the entire process, so as to avoid feed waste caused by abnormal temperature in tank 1.

[0024] Specifically, the controller 6 is equipped with start and stop buttons for the motor 7 and an embedded display screen for displaying the temperature of the first sensor 5, so as to intuitively observe and read the monitored temperature.

[0025] Specifically, both the driving wheel 8 and the driven wheel 10 are gears.

[0026] Specifically, the motor 7, controller 6, first sensor 5, drive wheel 8 and driven wheel 10 are all mature products on the market. They can be selected or customized according to design requirements. In addition to fixed type, the first sensor 5 can also be magnetic type. The display screen embedded in the controller 6 for displaying the temperature of the first sensor 5 is a supporting product for the first sensor 5.

[0027] A gap is provided between the lower end of the stirring rod 4 and the tank 1. The lower end of the stirring rod 4 is fixedly connected to the fixing seat 3. The stirring rod 4 is a hollow tube. The fixing seat 3 is detachably connected to the stirring rod 4. The fixing seat 3 is fixed with at least two sets of guide rods 13. The guide rods 13 are slidably connected to the counterweight slider 12 through the first spring. One end of the first spring is connected to the counterweight slider 12, and the other end of the first spring is fixedly connected to the guide rod 13. When the stirring rod 4 rotates, the centrifugal force generated by the counterweight slider 12 is greater than the elastic force of the first spring. The counterweight slider 12 is fixedly connected to the second sensor 11. The second sensor 11 is electrically connected to the controller 6. The controller 6 is also embedded with a display screen that can display the temperature value of the second sensor 11.

[0028] Furthermore, an electric slip ring 9 is rotatably connected to the top of the stirring rod 4. The fixed end of the electric slip ring 9 is fixedly connected to the tank body 1. The electric slip ring 9 is electrically connected to the controller 6. The second sensor 11 is electrically connected to the electric slip ring 9.

[0029] Specifically, the second sensor 11 is also a mature product on the market, using the model WZPK-191 from Suzhou Jingmin Sensor Co., Ltd. The probe diameter is 2mm and the length is 10mm. It adopts a shell-type packaging method with fast thermal response, which can protect the thermocouple during operation and thus extend the service life of the thermocouple. The diameter and length of the thermocouple probe can also be customized according to the wall thickness of the mounting base 3.

[0030] Specifically, the slip ring 9 is a mature product on the market. It uses the MZ086 series rotor flange conductive slip ring from Shenzhen MOFLON Technology Co., Ltd. This type of slip ring can achieve more channels and larger current, and can be used to customize various sensitive signals or encoder signals to achieve smooth power supply and signal transmission. It is widely used in industrial machine processing centers, rotary tables, heavy equipment towers, process control equipment, rotary sensors, robots, exhibition / display equipment, medical equipment, etc.

[0031] Specifically, the controller 6 drives the motor 7 to work, the drive wheel 8 drives the driven wheel 10 to rotate, which in turn rotates the stirring rod 4. Under the action of centrifugal force, the counterweight slider 12 compresses the first spring, causing the second sensor 11 to retract into the fixed seat 3, so that the end of the second sensor 11 is flush with the outer circumference of the fixed seat 3. When the motor 7 stops working, under the action of the first spring, the counterweight slider 12 is reset, and the second sensor 11 extends out of the fixed seat 3 to start measuring the temperature of the feed in the central area of ​​the tank 1. The first sensor 5 simultaneously measures the temperature in real time.

[0032] Example 2: Furthermore, since the second sensor 11 rotates synchronously with the stirring rod 4, the temperature measurement by the second sensor 11 is unstable and inaccurate during the rotation of the stirring rod 4, which is also detrimental to the protection of the second sensor 11 and can easily shorten its service life. To better enable the second sensor 11 to perform temperature measurement and extend its service life, please refer to the attached... Figure 3 Based on Embodiment 1, further modifications are made to the working state of the second sensor 11.

[0033] The lower end face of the drive wheel 8 is connected to a wedge-shaped slider 14 that can only slide horizontally via a tension spring. One end of the tension spring is connected to the center area of ​​the drive wheel 8, and the other end of the tension spring is connected to the wedge-shaped slider 14. At least two sets of wedge-shaped sliders 14 are evenly distributed on the drive wheel 8. The tension of the tension spring is less than the centrifugal force generated by the rotation of the wedge-shaped slider 14. When the drive wheel 8 rotates, it can make the wedge-shaped slider 14 move away from the center of the drive wheel 8.

[0034] Specifically, the wedge-shaped slider 14 and the drive wheel 8 are connected by a dovetail structure, or they can be connected by other methods.

[0035] The tank body 1 is slidably connected to a pressure ring 15 via a second spring. One end of the second spring is connected to the pressure ring 15, and the other end of the second spring is connected to the tank body 1. The pressure ring 15 can only slide up and down relative to the tank body 1. The pressure ring 15 is coaxial with the drive wheel 8. The elastic force of the second spring is less than the centrifugal force of the wedge slider 14. When the wedge slider 14 and the pressure ring 15 are engaged, the pressure ring 15 slides downward.

[0036] Furthermore, the wedge-shaped slider 14 is provided with a vertical surface 19, which can cooperate with the inner circumferential surface of the pressure ring 15.

[0037] A first conductive block 17 is fixed at a suitable position on the pressure ring 15, and a second conductive block 18 is fixed at a suitable position on the tank body 1. The first conductive block 17 and the second conductive block 18 cooperate to be electrically connected to the second sensor 11. When the pressure ring 15 slides downward, the first conductive block 17 and the second conductive block 18 can be separated, thereby de-energizing the second sensor 11.

[0038] Specifically, the rotation of the drive wheel 8 causes the wedge-shaped slider 14 to slide away from the center of the drive wheel 8 under centrifugal force. This causes the inclined surface of the wedge-shaped slider 14 to first contact the pressure ring 15. Under the continuous action of centrifugal force, the pressure ring 15 compresses the second spring downward under the action of the inclined surface of the wedge-shaped slider 14. Finally, the vertical surface 19 is brought into contact with the inner circumferential surface of the pressure ring 15, and the wedge-shaped slider 14 remains in contact with the inner circumferential surface of the pressure ring 15 under the action of centrifugal force. This causes the wedge-shaped slider 14 driven by the drive wheel 8 to make circular motion on the inner circumferential surface of the pressure ring 15. Simultaneously, the first conductive block 17 and the second conductive block 18 are separated, and the second sensor 11 is de-energized. The drive wheel 8 stops rotating, the wedge-shaped slider 14 is reset under the action of the tension spring, and the pressure ring 15 is reset under the action of the second spring. This reconnects the first conductive block 17 and the second conductive block 18, enabling power supply to the second sensor 11. The second sensor 11 then extends out of the fixed base 3 to measure the temperature of the feed in the central area of ​​the tank 1.

[0039] Example 3: Furthermore, since the wedge-shaped slider 14 moves in a circular motion on the inner circumference of the pressure ring 15, frictional heat is generated after prolonged operation, affecting the stability of the device. (Refer to the attached document.) Figure 3 Based on Example 2, further modifications were made to the pressure ring 15.

[0040] A bearing 16 is fixed on the inner circumferential surface of the pressure ring 15. The bearing 16 is a mature product on the market. Considering the operating environment of the device, the bearing 16 is selected to have a sealing function.

[0041] Specifically, under the action of centrifugal force, the wedge slider 14 keeps the vertical surface 19 in continuous contact with the inner circumferential surface of the bearing 16, so that when the drive wheel 8 drives the wedge slider 14 to rotate, the inner ring of the bearing 16 rotates, reducing friction and extending the service life of the device.

[0042] Example 4: Furthermore, since the vertical surface 19 of the wedge slider 14 is rigidly connected to the inner ring of the bearing 16 during operation, relative sliding will occur after long-term operation, affecting the stability of the device. (Refer to the attached diagram.) Figure 6 Based on Example 3, further modifications were made to the vertical plane 19.

[0043] A non-slip layer is fixed on the vertical surface 19. The non-slip layer can be made of rubber with non-slip function or silicone. The non-slip material is a mature product on the market.

[0044] Specifically, after the wedge-shaped slider 14 slides under centrifugal force, the anti-slip layer of the vertical surface 19 fits into the inner circumferential surface of the bearing 16, thus smoothly driving the inner ring of the bearing 16 to rotate.

[0045] Example 5: Furthermore, the anti-slip layer on vertical surface 19 is at risk of aging after prolonged use, and the friction decreases after repeated use, posing a potential risk of relative sliding with bearing 16. (Refer to the attached document.) Figure 4 , Figure 5 Based on Example 4, further modifications were made to the vertical plane 19.

[0046] A magnet 20 is fixed to the vertical surface 19. The anti-slip layer covers the magnet 20. The magnet 20 is a permanent magnet. The magnetic force of the magnet 20 is less than the tension of the tension spring. It is a mature product on the market.

[0047] Specifically, the anti-slip layer of the vertical surface 19 is in contact with the inner circumferential surface of the bearing 16, and the magnet 20 can attract the inner circumferential surface of the bearing 16. Under the action of the bearing 16, the relative rotation of the wedge slider 14 and the pressure ring 15 is realized. When the drive wheel 8 rotates, when the wedge slider 14 slides to the vicinity of the bearing 16, the attraction force of the magnet 20 and the centrifugal force can be combined to shorten the contact time between the vertical surface 19 and the inner circumferential surface of the bearing 16, further accelerating the separation of the first conductive block 17 and the second conductive block 18, making the second sensor 11 de-energized faster, which is more conducive to extending the service life of the second sensor 11. When the drive wheel 8 stops rotating, the tension spring can make the wedge slider 14 overcome the attraction force of the magnet 20 and reset.

[0048] It should be noted that this device also has an external power supply, which is not shown in the diagram.

[0049] The working principle and usage process of this utility model.

[0050] S1: The motor 7 is started by the controller 6, the active wheel 8 drives the passive wheel 10 to rotate, and the stirring rod 4 rotates. The first sensor 5 measures the temperature in real time.

[0051] S2: Under the centrifugal force of the rotating drive wheel 8, the wedge slider 14 slides away from the center of the drive wheel 8, causing the pressure ring 15 to slide downward, separating the first conductive block 17 from the second conductive block 18, thus de-energizing the second sensor 11. With the cooperation of the bearing 16, the vertical surface 19, the magnet 20, and the anti-slip layer, the wedge slider 14 and the pressure ring 15 can rotate smoothly relative to each other. At the same time, under the centrifugal force of the rotating stirring rod 4, the counterweight slider 12 drives the second sensor 11 to retract into the fixed seat 3.

[0052] S3: The motor 7 stops rotating through the controller 6, the wedge slider 14 is reset under the action of the tension spring, the constraint force of the pressure ring 15 is eliminated, the pressure ring 15 is reset under the action of the second spring, the first conductive block 17 and the second conductive block 18 re-cooperate, and the second sensor 11 is energized. At the same time, the counterweight slider 12 is reset under the action of the first spring, causing the second sensor 11 to extend out of the fixed seat, so as to measure the temperature of the feed in the central area of ​​the tank 1.

[0053] S4: After all is completed, open the sealing block 2 and transfer the feed in tank 1 to the subsequent process.
