Description

Technical Field

[0001] This invention relates to the field of total daily ration (TDRN) preparation machine manufacturing technology, and in particular to a vehicle-mounted TDRN preparation machine. Background Technology

[0002] In the livestock farming sector, Total Mixed Ration (TMR) machines are core equipment for achieving scientific and large-scale feeding. They are used to uniformly mix various raw materials such as roughage, concentrates, minerals, and vitamins according to a formula to produce a nutritionally balanced total mixed ration. With the development of intensive farming models, vehicle-mounted TMR machines are widely used due to their high mobility and wide applicability.

[0003] However, most existing total ration (TCR) production machines are driven by diesel tractors, and there are still several technical problems that need to be solved in terms of structural design, drive method, and system integration. These problems are specifically reflected in the following aspects: Firstly, traditional total ration preparation machines typically have ample chassis space at the bottom of the carriage, so the reducer is installed "from bottom to top," meaning it is vertically fixed to the bottom plate from the outside of the carriage. However, this installation method requires operators to crawl under the vehicle to work, which is difficult and time-consuming. This not only increases the difficulty and time cost of equipment maintenance but also restricts the improvement of equipment maintenance efficiency.

[0004] Secondly, traditional total ration (TRN) generator drive systems use hydraulic transmission, resulting in a complex system configuration that requires auxiliary components such as hydraulic pump stations, oil tanks, valve groups, and cooling devices. This not only increases the overall weight and fuel consumption but also leads to short maintenance cycles and the risk of hydraulic oil leakage. Over the long term, the overall operating cost of hydraulic drive systems is relatively high.

[0005] Third, traditional total ration (TCR) preparation machines often use a front-to-back or single-direction long-stroke discharge structure, which complicates the installation process and results in lower overall equipment reliability.

[0006] Fourth, traditional total ration (TRN) preparation machines typically have several sets of weighing sensors installed in a specific area of ​​the vehicle. The concentrated sensor layout makes it difficult to accurately characterize the weight distribution of materials, and the sensors are not securely installed, posing a risk of sensor damage and failure.

[0007] Fifth, traditional total ration (TCR) preparation machines cannot display relevant data in real time, resulting in a low level of intelligence.

[0008] In summary, there is an urgent need to research a new type of vehicle-mounted total daily ration (TDR) preparation machine that can effectively overcome the above problems. Summary of the Invention

[0009] The purpose of this invention is to provide a vehicle-mounted total ration (TCR) preparation machine to solve the problems existing in traditional TCR preparation machines in terms of structural design, drive method and system integration.

[0013] As a preferred embodiment, a vehicle-mounted total daily ration (TDR) preparation machine includes a weighing component comprising a first support column fixed to the rear of a crossbeam on the chassis of the vehicle, with a first weighing sensor fixedly mounted on both ends of the first support column, and a support component installed on the upper side of the pressure-bearing end of the first weighing sensor, the support component being fixedly installed at the bottom of the vehicle compartment.

A second weighing sensor is fixedly installed inside the fixed end sleeve. The pressure-bearing end of the second weighing sensor is fixedly installed at the bottom of the carriage through a support assembly. Triangular brackets are installed on the upper side of the head of each crossbeam. A second support column is fixedly inserted between two of the triangular brackets. A third load cell is fixedly fitted at both ends of the second support column. A vertical support plate is fixedly fitted at the pressure end of each third load cell. A support strip is fixedly connected to each vertical support plate along the length of the carriage. The support strip is installed at the bottom of the carriage.

[0014] The solution requires detailed explanation of a vehicle-mounted total daily ration (TDR) preparation machine, wherein the two supporting components include a load-bearing plate bolted to the pressure end of a first weighing sensor or a second weighing sensor, the load-bearing plate being fixed to a base plate, the base plate being fixedly installed at the bottom of the vehicle compartment, and a reinforcing plate being installed between the load-bearing plate and the base plate.

[0015] The solution requires further detailed explanation of a vehicle-mounted total daily ration (TDR) preparation machine, wherein weight display screens are installed on both sides of the vehicle compartment, and the weight display screens are electrically connected to the display host.

[0016] In a preferred embodiment, a vehicle-mounted total daily ration (TDR) preparation machine is provided. The drive assembly includes a drive motor that is fixedly connected to the vehicle chassis via the connecting mounting plate. The drive motor is electrically connected to the motor driver and is located below the motor driver. One end of the output shaft of the drive motor is connected to a reducer corresponding to the bladed spiral rotor inside the vehicle via a universal coupling and a connecting shaft. The reducer is suspended from top to bottom through the mounting hole via the connecting assembly and connected to the bottom of the bladed spiral rotor.

[0017] The solution requires further detailed explanation of a vehicle-mounted total daily ration (TDR) preparation machine. The connecting assembly includes a transition flange connected to the lower floor plate of the vehicle body by bolts, a reducer flange and a reducer mounting flange fixed to the outer periphery of the reducer, and a connecting flange fixed to the output shaft of the reducer and the bottom of the bladed screw rotor. An annular baffle plate is fixed between the transition flange and the reducer mounting flange. The reducer flange and the reducer mounting flange are connected by bolts. The reducer and the bladed screw rotor are fixedly connected through the connecting flange.

[0018] The solution requires further elaboration on a vehicle-mounted total ration preparation machine, wherein a tapered tube is fixed to the outer periphery of the bottom connecting flange of the bladed spiral rotor, and the bottom of the tapered tube extends to the annular baffle plate.

[0019] The solution requires further detailed explanation of a vehicle-mounted total ration (TCR) preparation machine, wherein the installation method of the reducer and the bladed screw rotor includes: Mounting holes corresponding to the bladed spiral rotor are provided on the lower bottom plate of the carriage. The diameter of the mounting holes is larger than the maximum outer diameter of the reducer housing and smaller than the outer diameter of the transition flange. The transition flange and the reducer mounting flange are welded together by means of an annular baffle plate, and the reducer flange and the reducer mounting flange are bolted together to form a combination with the reducer; The assembly is installed from top to bottom through the mounting holes onto the lower floor plate of the carriage, and the transition flange is made to abut against the inner side of the lower floor plate of the carriage. The transition flange is then fixed to the lower floor plate of the carriage with bolts. The bladed spiral rotor is hoisted into the carriage, and the bottom connecting flange of the bladed spiral rotor is aligned with the connecting flange at the top of the output shaft of the reducer. Then, the two connecting flanges are fixedly connected by bolts. The tapered tube is fixed to the outer periphery of the bottom connecting flange of the bladed spiral rotor, and the bottom of the tapered tube extends to the annular baffle plate. The exposed part of the reducer is connected to the connecting shaft via a universal coupling.

[0020] Compared with the prior art, the vehicle-mounted total ration preparation machine provided by the present invention has at least the following beneficial effects: 1. By integrating electrical components such as the motor driver and circuit board into the protective shell at the front of the truck bed, and using heat dissipation plates on the inner sidewalls of the protective shell, efficient integration of the drive system and the vehicle body structure is achieved. Simultaneously, the use of a battery pack to power the drive components replaces the hydraulic transmission of traditional fuel-powered tractors, reducing fuel consumption and maintenance costs. Furthermore, the use of weighing components distributed at the front, middle, and rear of the chassis accurately characterizes the weight distribution of materials within the truck bed, avoiding measurement deviations and potential damage risks caused by the centralized arrangement of traditional weighing sensors, significantly improving weighing accuracy and system reliability.

[0021] 2. By installing discharge output components on both sides of the front end of the carriage, a bidirectional short-stroke discharge structure is achieved, which not only enables uniform and efficient discharge operations but also simplifies the installation process and improves the overall operational reliability of the equipment. The display host enables real-time display of material weight, allowing operators to easily monitor the loaded weight information. Centralized monitoring and management of weighing data, discharge control, and drive status are achieved, significantly enhancing the equipment's intelligence level.

[0022] 3. By adopting a "top-down" installation method for the reducer and the bladed screw rotor, that is, the reducer assembly is inserted from the bottom of the carriage through the mounting hole from top to bottom and fixedly connected to the bottom plate via the transition flange, the operator can complete the installation without crawling under the carriage, which greatly reduces the difficulty of installation and disassembly and shortens the equipment maintenance time. At the same time, the combination of the annular baffle plate and the tapered tube effectively prevents materials from entering the reducer installation area along the bottom of the bladed screw rotor, ensuring the safety and reliability of the reducer operation.

[0026] The core of this invention is to provide a vehicle-mounted total ration (TCR) preparation machine to solve the problems existing in traditional TCR preparation machines in terms of structural design, drive method and system integration.

[0028] Example 1 A vehicle-mounted total mixed ration (TMR) preparation machine includes: a chassis 1, a cargo box 2, and a driver's cab 3. A protective shell 4 and a motor driver and circuit board (not shown) are installed at the front end of the cargo box 2. A heat dissipation plate (not shown) is installed on the inner wall of the protective shell 4 to dissipate heat generated by the motor driver and circuit board during operation, ensuring that the electrical components operate within a suitable temperature range. Ventilation holes are provided on the top or side walls of the protective shell 4, and dust screens are installed at the ventilation holes to facilitate the convection and discharge of hot air. Discharge output components 5 are installed on both sides of the front end of the cargo box 2 to discharge the prepared TMR from both sides of the front end of the cargo box 2. A ladder 17 is installed at the rear end of the cargo box 2 to facilitate operators to climb and inspect and maintain the interior of the cargo box 2. A reducer oil reservoir 1240 is also installed on the outside of the cargo box 2 to supply oil to the reducer 124. A guide plate 02 is installed inside the cargo box 2 to prevent material from remaining between the two bladed spiral rotors 13 at the bottom of the cargo box 2 and being unable to be discharged.

[0029] The chassis 1 has a cab 3 mounted at the front and headlights 6 and a bumper 7 mounted at the rear. A heat shield 30 is located on the rear side of the cab 3 near the battery pack 8. The battery pack 8, located behind the cab 3, is mounted on the chassis 1 via a battery mounting bracket 01. The battery pack 8 serves as the power source for the entire vehicle, providing power to the drive assembly 12 and various electrical devices. Weighing components 9 are installed on the chassis 1 at the front, middle, and rear positions. The cargo box 2 is mounted on the weighing components 9. Through the combined action of the three weighing components 9, accurate measurement of the weight and weight distribution monitoring of the materials inside the cargo box 2 are achieved.

[0030] An integrated controller display host 10 is installed in the cab 3. The display host 10 is electrically connected to the weighing component 9 and the discharge output component 5, respectively, to receive the weight signal detected by the weighing component 9 and control the start, stop, and operating status of the discharge output component 5. A drive component 12 is mounted on the chassis 1 near the battery pack 8 via a connecting mounting plate 11. The drive component 12 is hoisted from top to bottom through mounting holes 15 at the bottom of the cargo compartment 2 and connected to the bladed spiral rotor 13 inside the cargo compartment 2, to drive the bladed spiral rotor 13 to rotate, thereby cutting, mixing, and stirring various feed ingredients inside the cargo compartment 2. A motor driver is electrically connected to both the battery pack 8 and the drive component 12. The motor driver converts the DC power from the battery pack 8 into electrical energy suitable for the operation of the drive component 12 and controls the speed and direction of the drive component 12. A circuit board is electrically connected to both the display host 10 and the motor driver, respectively, for signal conversion and transmission.

[0031] This embodiment integrates electrical components within the protective housing 4, powered by the battery pack 8 and driven by the motor driver, replacing the hydraulic transmission method of traditional fuel-powered tractors. This simplifies the overall vehicle power system structure, avoids the risk of hydraulic oil leakage, and reduces fuel consumption and maintenance costs. Simultaneously, the use of front, middle, and rear distributed weighing components 9 accurately characterizes the weight distribution of materials within the cargo box 2, improving weighing accuracy and system reliability.

[0032] Example 2 Based on Embodiment 1, this embodiment further defines the specific structure of the discharge output component 5. The discharge output component 5 includes: discharge ports (not shown in the figure) located on both sides of the front end of the carriage 2, a lateral mounting plate 51 installed on the side of the discharge port, and a bottom mounting plate 52 installed on the chassis 1 and located below the discharge port; the carriage 2 is used to accommodate the total mixed ration after being mixed and stirred by the bladed spiral rotor 13. The opening position of the discharge port corresponds to the pushing end of the bladed spiral rotor 13 inside the carriage 2, so that the material is pushed to the discharge port under the action of the bladed spiral rotor 13.

[0033] A baffle plate 53 is installed on the side of the side mounting plate 51 and the bottom mounting plate 52 facing the discharge direction. The baffle plate 53 is designed to prevent material from piling up on the side discharge belt 57 and improve the uniformity of discharge. A drive shaft 54 ​​and a driven shaft 55 are rotatably mounted on the bottom mounting plate 52. The drive shaft 54 ​​is located closer to the side of the carriage 2, and the driven shaft 55 is located away from the side of the carriage 2. A hydraulic motor 56 is fixedly mounted to the mounting bracket 520 on the outside of the bottom mounting plate 52 by bolts. The output shaft of the hydraulic motor 56 is connected to the drive shaft 54 ​​via a coupling. The hydraulic motor 56 is connected to the oil supply line of the vehicle's hydraulic system, and its start, stop, and speed are controlled by the control valve on the main display unit 10 in the cab 3. The drive shaft 54 ​​is driven by the hydraulic motor 56, and the side discharge belt 57 is installed on the drive shaft 54 ​​and the driven shaft 55. The hydraulic motor 56 drives the drive shaft 54 ​​to rotate, which in turn drives the driven shaft 55 to rotate synchronously via the side discharge belt 57, thereby conveying the material discharged from the carriage 2 to both sides of the front end of the carriage 2. In other words, the material in the carriage 2 falls from the discharge port and is discharged outward along the conveying direction (width direction of the carriage) of the side discharge belt 57, falling into the receiving vehicle parked on the side or at a designated location.

[0034] A vertically extending ridge 58 is provided on the outer side of the carriage 2 near the discharge port. A groove 59 is provided on the inner side of the ridge 58, facing the center of the discharge port. A hydraulic cylinder 60 is fixedly installed on the upper outer side of the carriage 2. The hydraulic cylinder 60 is supplied with oil through an oil supply line 600. The piston rod of the hydraulic cylinder 60 extends vertically downwards and has a door 61. The left and right edges of the door 61 are slidably fitted into the grooves 59 on both sides. The extension and retraction of the hydraulic cylinder 60 causes the door 61 to slide up and down along the grooves 59, thereby opening and closing the discharge port. When discharge is needed, the hydraulic cylinder 60 retracts, the door 61 slides upwards, the discharge port opens, and the material falls onto the lateral discharge belt 57 under the action of gravity and the thrust of the bladed spiral rotor 13. After discharge, the hydraulic cylinder 60 extends, the door 61 slides downwards, gradually blocking the discharge port and finally pressing it against the upper surface of the lateral discharge belt 57, closing the discharge port. By controlling the extension of the hydraulic cylinder 60, the opening of the gate 61 can be adjusted, thereby controlling the discharge flow rate.

[0035] The display host 10 is electrically connected to the hydraulic motor 56 and the oil cylinder 60 respectively. The operator can control the start, stop and speed of the hydraulic motor 56 and the extension and retraction of the oil cylinder 60 through the display host 10 to realize centralized control of the material discharge operation.

[0036] In this embodiment, by setting up a bidirectional discharge structure on both sides of the front end of the carriage 2, and cooperating with the lateral discharge belt 57 for material conveying, uniform and efficient discharge operation is achieved. At the same time, by driving the door 61 to rise and fall along the slide 59 through the hydraulic cylinder 60, flexible opening and closing control of the discharge port is achieved, which improves the convenience and automation level of the discharge operation.

[0037] Example 3 Based on Example 2, this example further defines the belt tensioning structure of the discharge output component 5.

[0038] The discharge output assembly 5 also includes a mounting base 62 installed on the bottom mounting plate 52, on which a belt tensioning screw 63 is screwed. Correspondingly, an installation notch 64 is provided at the outer end of the bottom mounting plate 52 (i.e., the side away from the carriage 2). The installation notch 64 is an elongated through groove along the conveying direction of the lateral discharge belt 57. A connecting plate 65 is slidably installed at the installation notch 64, and a driven shaft 55 is rotatably installed on the connecting plate 65. The connecting plate 65 can slide back and forth along the length of the installation notch 64, and the driven shaft 55 is rotatably installed on the connecting plate 65 through a bearing. One end of the belt tensioning screw 63 passes through the mounting base 62, and the other end is rotatably connected to the connecting plate 65 (i.e., the two can rotate relative to each other, but axial displacement is limited). Nuts 66 located on both sides of the mounting base 62 are screwed onto the belt tensioning screw 63. After installation, the nuts 66 are fixedly connected to the mounting base 62.

[0039] When tensioning of the lateral discharge belt 57 is required, the operator can adjust the tension by turning the belt tensioning screw 63, which allows the connecting plate 65 to slide outward or inward along the mounting notch 64. This adjusts the distance between the driven shaft 55 and the driving shaft 54, thereby adjusting the tension of the lateral discharge belt 57. This adjustment process does not require drilling under the vehicle, significantly reducing maintenance difficulty and shortening maintenance time.

[0040] In practical design, several raised scraping ribs 570 can be spaced along the conveying direction on the surface of the side discharge belt 57. The cross-section of the scraping ribs 570 is trapezoidal or semi-circular. The scraping ribs 570 and the side discharge belt 57 can be made using an integral vulcanization molding process to enhance the connection strength; alternatively, they can be made as independent rubber strips that are detachably connected to the surface of the side discharge belt 57 using fasteners such as bolts and rivets, so as to facilitate individual replacement after wear. A sealing strip made of wear-resistant rubber or polyurethane material can also be fixedly embedded at the lower edge of the door 61. When the hydraulic cylinder 60 drives the door 61 to the closed position, the bottom surface of the sealing strip abuts tightly against the upper surface of the side discharge belt 57, forming a seal. This abutting state can effectively prevent material leakage and can also clean residual material on the surface of the side discharge belt 57 by friction when the side discharge belt 57 is accidentally started.

[0041] In this embodiment, the gate 61 is initially in the closed position. When the vehicle reaches the feeding area, the hydraulic motor 56 is activated to drive the lateral discharge belt 57. The operator controls the cylinder 60 to retract, raising the gate 61. The mixed feed in the compartment 2 is pushed axially by the bladed spiral rotor 13 to the discharge port. The material falls onto the lateral discharge belt 57 under the action of gravity and the bladed spiral rotor 13, and is transported laterally (i.e., perpendicular to the vehicle's direction of travel) to an external receiving vehicle or a designated location under the friction of the belt and the scraping action of the scraping ribs 570. After feeding is completed, the control cylinder 60 extends, the gate 61 descends and closes, and the sealing strip presses against the surface of the lateral discharge belt 57 to achieve effective sealing.

[0042] Example 4 Based on Example 1, this example further defines the specific structure of the symmetrical component 9.

[0043] The crossbeam 18 is a support component in the chassis 1. There are two crossbeams 18, which extend horizontally along the length of the carriage 2. After installation, the carriage 2 is located above the crossbeam 18 but does not directly contact it.

[0044] The weighing assembly 9 includes a first support column 91 fixed to the rear of a crossbeam 18 on the chassis 1. The first support column 91 is a cylindrical metal rod with both ends extending from the outside of the crossbeam 18. Two first load cells 92 are fixedly mounted on both ends of the first support column 91. The two first load cells 92 are located on the outside of the two crossbeams 18 and are used to detect the load on the left and right sides of the rear of the carriage 2. The first load cell 92 has a cylindrical structure, with one end as the mounting end and the other as the bearing end. To ensure the correct installation of the first load cell 92, end sleeves for installation are provided at both ends of the first support column 91. The mounting end of the first load cell 92 is horizontally inserted into the end sleeves at both ends of the first support column 91.

[0045] A support assembly is installed on the upper side of the pressure-bearing end of the first weighing sensor 92. The support assembly is fixedly installed at the bottom of the carriage 2. The load at the rear of the carriage 2 is transferred to the pressure-bearing end of the first weighing sensor 92 through the support assembly. Through the cooperation of the first support column 91 and the two first weighing sensors 92, the weight at the rear of the carriage 2 is detected.

[0046] An auxiliary support frame 94 is fixedly strung between the two crossbeams 18. The upper side of the auxiliary support frame 94 is flat and does not contact the bottom of the carriage 2, while the lower side is V-shaped to facilitate the installation of the drive shaft. The lower side is welded between the two crossbeams 18. To ensure stability, a groove is first cut into the lower side of the auxiliary support frame 94, which is then inserted into the crossbeam 18 before welding. This ensures the stability of the auxiliary support frame 94. Fixed end sleeves 95 are fixedly installed at both ends of the auxiliary support frame 94. The fixed end sleeves 95 are horizontally arranged cylindrical structures. A second load cell 96 is fixedly installed inside the fixed end sleeve 95. The pressure-bearing end of the second load cell 96 extends horizontally out of one side of the fixed end sleeve 95 and is fixedly installed at the bottom of the carriage 2 via a support assembly. The load in the middle of the carriage 2 is transferred to the pressure-bearing end of the second load cell 96 through the support assembly. Through the cooperation of the auxiliary support frame 94 and the two second load cells 96, the weight in the middle of the carriage 2 is detected.

[0047] Triangular brackets 97 are installed on the upper side of the head (i.e., the front of the vehicle) of the crossbeam 18. Each triangular bracket 97 is a triangular support structure, with its bottom fixed to the upper surface of the crossbeam 18 and its top extending upwards. A second support column 98 is fixedly inserted between the two triangular brackets 97. The second support column 98 has the same structure as the first support column 91, being a cylindrical metal rod. Both ends of the second support column 98 extend from the outside of the two triangular brackets 97. A third load cell 99 is fixedly fitted onto both ends of the second support column 98. Similarly, both ends of the second support column 98 are also provided with end sleeves for installation. The mounting ends of the third load cells 99 are installed inside the end sleeves at both ends of the second support column 98. The two third load cells 99 are located on the outside of the two triangular brackets 97. Each third load cell 99 has a vertical support plate 100 fixedly fitted to its pressure-bearing end. The vertical support plate 100 is a vertically arranged plate-shaped component, with its lower end fixedly fitted onto the pressure-bearing end of the third load cell 99 and its upper end extending upwards towards the carriage 2 and fixed to the structural components on the side of the carriage 2. Each vertical support plate 100 is fixedly connected to a support bar 101 arranged along the length of the carriage 2. The support bar 101 is installed at the bottom of the carriage 2, and the load at the head of the carriage 2 is transferred to the pressure-bearing end of the third load cell 99 through the support bar 101 and the vertical support plate 100. At the same time, the support bar 101 significantly increases the stability of the third load cell 99 in bearing the load of the carriage 2. In this embodiment, multiple auxiliary support plates 1011 are also connected between two support bars 101. The multiple auxiliary support plates 1011 extend along the length of the carriage 2, and their two ends are fixedly connected to the two support bars 101 respectively, to increase the overall rigidity and load uniformity of the support bars 101.

[0048] A limiting sleeve 102 is fixedly installed at the end of the pressure-bearing end of the third weighing sensor 99. The limiting sleeve 102 is a circular component that is sleeved on the end of the pressure-bearing end of the third weighing sensor 99 and fixed by bolts. It is used to limit the axial displacement of the vertical support plate 100 on the pressure-bearing end and prevent the vertical support plate 100 from coming off. Through the cooperation of the triangular bracket 97, the second support column 98, the two third weighing sensors 99, the vertical support plate 100 and the support bar 101, the weight of the front of the carriage 2 is detected.

[0049] The first support column 91 and the first weighing sensor 92, the fixed end sleeve 95 and the second weighing sensor 96, and the second support column 98 and the third weighing sensor 99 are all connected and fixed by a fixing pin 103. The fixing pin 103 passes through the corresponding support column, the fixed end sleeve 95 and the weighing sensor radially to prevent the weighing sensor from rotating or sliding axially on the support column or the fixed end sleeve 95, and is easy to disassemble and assemble.

[0050] In this embodiment, multiple connecting stiffeners 180 are installed between the two crossbeams 18. The inner sides of the two crossbeams 18 are welded to the connecting stiffeners 180 to form an integral frame structure, which can significantly improve the stability between the two crossbeams 18. Its shape is similar to that of the auxiliary support frame 94, with a planar structure on the upper side that does not contact the bottom of the carriage 2, and a V-shaped structure on the lower side, which facilitates the installation of the drive shaft and avoids interference.

[0051] The display host 10 is electrically connected to the first weighing sensor 92, the second weighing sensor 96, and the third weighing sensor 99 via a data junction box 104 installed on one side of the support bar 101. The weight signals detected by each weighing sensor are collected by the data junction box 104 and transmitted to the display host 10, where the display host 10 processes and displays the data.

[0052] This embodiment utilizes multiple sets of weighing sensors distributed at the front, middle, and rear to achieve weight distribution monitoring across the entire length of the carriage 2, effectively preventing sensor damage or failure due to off-center loading or vibration, and extending the equipment's service life. In this embodiment, the first weighing sensor 92, the second weighing sensor 96, and the third weighing sensor 99 are all mobile weighing sensors with anti-off-center loading and anti-vibration performance, suitable for vehicle-mounted mobile conditions.

[0053] Example 5 Based on Example 4, this example further defines the specific structure of the support component.

[0054] The two support components include a load-bearing plate 931 bolted to the pressure-bearing end of the first load cell 92 or the second load cell 96. The load-bearing plate 931 is a vertically arranged thick metal plate with an arc-shaped groove on its lower surface, which can be fitted across the pressure-bearing end of the first load cell 92 or the second load cell 96 and is fixedly connected by bolts. The load-bearing plate 931 is welded to the base plate 932, which is bolted to the bottom of the carriage 2, facilitating disassembly of the base plate 932 from the carriage 2 during maintenance. A reinforcing plate 933 is also installed between the load-bearing plate 931 and the base plate 932. The reinforcing plate 933 is a vertically symmetrical rib structure. The installation of the reinforcing plate 933 effectively improves the structural strength of the support components, ensuring that the weight of the carriage 2 can be stably and reliably transmitted to each load cell.

[0055] Example 6 Based on Embodiment 5, this embodiment installs weight display screens 14 on both sides of the carriage 2. The weight display screens 14 are digital displays and are electrically connected to the display host 10. The display host 10 transmits the weight data detected by the weighing component 9 to the weight display screens 14 for real-time display, allowing operators to monitor the loading weight information at different locations at any time. This, in conjunction with the display host 10, enables centralized monitoring and management of weighing data.

[0056] During feed loading, the weight of the truck bed 2 is transmitted to the first weighing sensor 92, the second weighing sensor 96, and the third weighing sensor 99 through various support components and structures. Specifically, the weight at the rear of the truck bed 2 is transmitted to the first weighing sensor 92 through the support components; the weight in the middle of the truck bed 2 is transmitted to the second weighing sensor 96 through the support components; and the weight at the front of the truck bed 2 is transmitted to the third weighing sensor 99 through the support bar 101 and the vertical support plate 100. Each of the six weighing sensors detects its own weight signal and transmits the detected weight signal to the display host 10. The display host 10 summarizes, processes, and calculates the signals from each sensor to determine the total weight of the material in the truck bed 2, and transmits the weight data to the display screen of the display host 10 in the driver's cab 3 and the weight display screens 14 on both sides of the truck bed 2 for real-time display. During feed preparation, the driver can adjust the amount of each ingredient added in a timely manner based on the real-time weight data displayed on the display host 10 to ensure the accuracy of the ration formula.

[0057] Example 7 Based on Embodiment 1, this embodiment further defines the specific structure of the driving component 12.

[0058] The drive assembly 12 includes a drive motor 121 fixedly connected to the chassis 1 via a connecting mounting plate 11. The drive motor 121 is electrically connected to a motor driver and is located below the motor driver. The connecting mounting plate 11 is welded and fixedly connected to the crossbeam 18. The drive motor 121 passes through the connecting mounting plate 11 and is fixedly connected to it. The drive motor 121 is a permanent magnet synchronous motor, and its output shaft extends horizontally along the front-rear direction of the vehicle. The motor driver is electrically connected to the battery pack 8 via a high-voltage power cable, and the motor driver is electrically connected to the drive motor 121 via a cable. The motor driver is used to convert the DC power output from the battery pack 8 into electrical energy suitable for the operation of the drive motor 121, and to adjust the speed and torque of the drive motor 121 according to control commands. One end of the output shaft of the drive motor 121 is connected to a reducer 124 corresponding to the bladed spiral rotor 13 inside the vehicle compartment 2 via a universal coupling 122 and a connecting shaft 123. Specifically, apart from the final reducer 124, each of the remaining reducers 124 corresponds to two universal couplings 122, and the output shaft of the drive motor 121 is also connected to a universal coupling 122. The universal couplings 122 are preferably cross-type universal couplings, allowing for a certain axial angle between the input and output ends. The universal couplings 122 effectively compensate for angular deviations and axial displacements between the output shaft of the drive motor 121 and the input shaft of the reducer 124, thereby compensating for installation errors and frame deformation during vehicle operation, ensuring smooth power transmission. The connecting shaft 123 is a solid round shaft, and its length is determined based on the distance between the output shaft of the drive motor 121 and the input shaft of the reducer 124. The reducer 124 is a Commail 30 cubic meter traction reducer.

[0059] The reducer 124 is hoisted from top to bottom through the mounting hole 15 via the connecting assembly 125 and connected to the bottom of the bladed screw rotor 13. The diameter of the mounting hole 15 is larger than the maximum outer diameter of the reducer 124 housing and smaller than the outer diameter of the transition flange 1251, so that after the reducer 124 passes through the mounting hole 15 from top to bottom, the transition flange 1251 can be locked inside the lower floor plate 19 of the carriage 2.

[0060] The drive motor 121 rotates under the control of the motor driver. The power is transmitted to the reducer 124 through the universal coupling 122 and the connecting shaft 123. After the reducer 124 reduces the speed and increases the torque, it transmits the power to the bladed spiral rotor 13, which drives the bladed spiral rotor 13 to rotate, cutting and mixing the material in the carriage 2.

[0061] Example 8 Based on Embodiment 7, this embodiment further defines the specific structure of the connecting component 125.

[0062] The connecting assembly 125 includes a transition flange 1251 bolted to the lower base plate 19 of the carriage 2, a reducer flange 1252 and a reducer mounting flange 1253 fixed to the outer periphery of the reducer 124, and a connecting flange 1254 fixed to the output shaft of the reducer 124 and the bottom of the bladed screw rotor 13. The reducer flange 1252 and the reducer mounting flange 1253 are preferably integrally cast with the reducer 124 housing or fixed by welding, and are located slightly above the axial center of the reducer 124 housing. An annular baffle 1255 is welded and fixed between the transition flange 1251 and the reducer mounting flange 1253, further preventing material from seeping downwards into the mounting hole 15 area. The reducer flange 1252 and the reducer mounting flange 1253 are bolted together, and the reducer 124 and the bladed screw rotor 13 are fixedly connected by the connecting flange 1254. The connecting flange 1254 includes an upper connecting flange and a lower connecting flange. The upper connecting flange is fixed to the bottom of the bladed spiral rotor 13, and the lower connecting flange is fixed to the top of the output shaft of the reducer 124. The upper and lower connecting flanges are coaxially fixedly connected by bolts. Thus, the output shaft of the reducer 124 is fixedly connected to the bottom of the bladed spiral rotor 13 through the connecting flange 1254, realizing torque transmission.

[0063] The connecting flange 1254, transition flange 1251, reducer flange 1252, and reducer mounting flange 1253 are all annular. The outer diameter of the transition flange 1251 is larger than the diameter of the mounting hole 15. The transition flange 1251 is fixedly connected to the lower base plate 19 by bolts. The reducer flange 1252 and reducer mounting flange 1253 are connected by bolts, and the bolts are evenly distributed around the circumference of the transition flange 1251 or the reducer flange 1252 and reducer mounting flange 1253.

[0064] Example 9 Based on Embodiment 8, this embodiment further includes a tapered tube 16 fixed to the outer periphery of the bottom connecting flange 1254 of the bladed spiral rotor 13. The bottom of the tapered tube 16 extends to the annular baffle plate 1255. The tapered tube 16 and the annular baffle plate 1255 together form a material isolation barrier, effectively guiding the material to slide down the outer wall of the tapered tube 16, preventing material accumulation in the installation area of ​​the reducer 124, and preventing wear and corrosion of the reducer 124 output shaft and sealing structure. The tapered tube 16 is a frustoconical tubular structure, with its lower diameter larger than its upper diameter, exhibiting a shape that is smaller at the top and larger at the bottom. The upper edge of the tapered tube 16 is welded and fixedly connected to the outer periphery of the connecting flange 1254, and the bottom (i.e., the larger end) of the tapered tube 16 extends to the annular baffle plate 1255, maintaining an axial clearance with the inner bottom of the carriage 2 to avoid motion interference. The tapered tube 16 rotates along with the bladed spiral rotor 13 when it rotates, and can use centrifugal force to throw the material outward, preventing the material from accumulating on the upper surface of the annular baffle 1255, and further enhancing the leak prevention effect.

[0065] Example 10 Based on Example 9, this example provides a more detailed description of the installation method of the reducer 124 and the bladed spiral rotor 13.

[0066] The installation method of the reducer 124 and the bladed screw rotor 13 includes the following steps: Step 1: A mounting hole 15 corresponding to the bladed screw rotor 13 is made on the lower base plate 19 of the carriage 2. The diameter of the mounting hole 15 is larger than the maximum outer diameter of the reducer 124 housing and smaller than the outer diameter of the transition flange 1251. The diameter design of the mounting hole 15 ensures that the reducer 124 can pass smoothly through the mounting hole 15, while allowing the transition flange 1251 to overlap on the lower base plate 19.

[0067] Step two: The transition flange 1251 and the reducer mounting flange 1253 are welded together using the annular baffle plate 1255. The reducer flange 1252 and the reducer mounting flange 1253 are then bolted together to form an assembly with the reducer 124. In other words, before installing the reducer 124 into the carriage 2, the transition flange 1251, the annular baffle plate 1255, the reducer mounting flange 1253, and the reducer flange 1252 are pre-assembled with the reducer 124 into a single unit to facilitate subsequent overall hoisting.

[0068] Step three: Install the assembly from top to bottom through the mounting hole 15 onto the lower floor plate 19 of the carriage 2, ensuring the transition flange 1251 abuts against the inner side of the lower floor plate 19. Then, secure the transition flange 1251 to the lower floor plate 19 of the carriage 2 with bolts, ensuring a reliable seal. During this installation process, the operator vertically lowers the assembly into the mounting hole 15 from inside the carriage 2, ensuring the output shaft of the reducer 124 faces upwards. The operator does not need to crawl under the carriage; the operation can be completed from inside the carriage 2 and above the lower floor plate 19, significantly reducing the installation difficulty.

[0069] Step four: Hoist the bladed screw rotor 13 into the carriage 2, aligning the bottom connecting flange 1254 of the bladed screw rotor 13 with the top connecting flange 1254 of the output shaft of the reducer 124. Then, secure the two connecting flanges 1254 together with bolts. This step is also completed inside the carriage 2, making the operation convenient.

[0070] Step 5: Fix the tapered tube 16 to the outer periphery of the bottom connecting flange 1254 of the bladed spiral rotor 13, and extend the bottom of the tapered tube 16 to the annular baffle plate 1255 to form a material isolation structure. Specifically, the upper small end of the tapered tube 16 is welded and fixed to the connecting flange 1254, ensuring that the axis of the tapered tube 16 coincides with the axis of the bladed spiral rotor 13. After installation, the bottom of the tapered tube 16 maintains a circumferential gap with the annular baffle plate 1255 to ensure that the tapered tube 16 can operate normally with the bladed spiral rotor 13.

[0071] Step six: Connect the exposed part of the reducer 124 to the connecting shaft 123 through the universal coupling 122, thereby realizing the complete power transmission path from the drive motor 121 to the bladed spiral rotor 13.

[0072] In actual installation, it is important to note that after the connecting flange 1254 and the tapered tube 16 are installed, manually rotate the bladed spiral rotor 1 to 2 turns to check for any jamming or abnormal noise. After confirming that there is no interference between the bottom of the tapered tube 16 and the annular baffle 1255, then perform the final tightening.

[0073] Using the above installation method, the installation and disassembly of the reducer 124 and the bladed spiral rotor 13 can be completed inside and above the carriage 2, without the need to crawl under the carriage, greatly reducing the difficulty of installation and disassembly and shortening equipment maintenance time. In the actual installation process, alignment lines can be marked on the outside of the reducer 124 and on the lower base plate 19 to avoid deviations in the installation of the reducer 124 and failure to align it with the connecting shaft 123.
