[0001] The utility model relates to the technical field of agricultural machinery, in particular to a control and monitoring device for a stubble tiller. Background Art

[0002] Stubble removal involves clearing the soil and removing the stubble left behind by the autumn crop harvest. Stubble removal plays a vital role in agriculture. In arid regions, shallow tillage is a moisture-conserving farming practice. By loosening the topsoil and breaking up crop residue, it cuts soil capillaries, reduces evaporation, and conserves soil moisture. With the widespread adoption of agricultural mechanization, stubble removal is now performed by rotary tillers.

[0003] Through searching, a stubble destroyer with publication number CN221532052U is found, which includes a frame, an engine is provided on the upper surface of the front end of the frame, one end of the engine is connected to a gearbox, a transmission mechanism is provided on one side of the frame, two gears of the second driven gear group of the transmission mechanism are respectively connected to one end of the stubble destroying roller and the rotary tillage roller, the other ends of the stubble destroying roller and the rotary tillage roller are rotatably connected to a side of the frame away from the transmission mechanism, the output shaft end of the gearbox is connected to the driving gear of the transmission mechanism, a scraper plate is provided on the frame behind the rotary tillage roller, a walking wheel is provided behind the scraper plate, and a pressing roller and a shaping roller are provided behind the walking wheel in sequence.

[0004] The above-mentioned stubble chopper is connected to the rear of a large tractor. Since the stubble chopper is large, its working power comes from its own engine. However, the stubble chopper has the following problems: first, the temperature and water volume of the cooling water of the stubble chopper engine cannot be monitored in real time; second, the temperature of the circulating cooling lubricating oil of a large number of gears in the transmission mechanism cannot be monitored in real time. Utility Model Content

[0005] In response to the existing problems, the utility model provides a stubble tiller control and monitoring device to solve the problem mentioned in the background technology that the temperature and water volume of the stubble tiller engine cooling water cannot be monitored in real time and the temperature of the circulating cooling lubricating oil of a large number of gears in the transmission mechanism cannot be monitored in real time.

[0006] In order to solve the existing problems, the utility model provides a control and monitoring device for a stubble tiller, including a power supply, a display, and a controller. The power supply and the display are electrically connected to the controller. The controller is electrically connected to a temperature sensor A, a water volume sensor, and a temperature sensor B, respectively. The temperature sensor A and the water volume sensor are installed on the cooling water tank of the engine to detect the temperature and water volume of the coolant. The temperature sensor B is installed on the gear transmission mechanism to monitor the temperature of the circulating lubricating oil inside the gear transmission mechanism.

[0007] The controller is electrically connected to a reduction motor that controls an engine throttle via a pull wire, and the controller is electrically connected to a starter installed on the engine for starting the engine.

[0008] Furthermore, the controller is electrically connected to a camera installed on the stubble tiller.

[0009] Furthermore, the temperature sensor A, water volume sensor and temperature sensor B are all equipped with protective devices, and the protective devices include a lower protective shell and an upper protective shell. The outer side of the lower end of the lower protective shell is provided with an external thread, and the inner and outer sides of the upper end of the lower protective shell are provided with threads. The outer side of the lower end of the upper protective shell is provided with an external thread that is compatible with the inner thread of the lower protective shell, and the lower end of the lower protective shell and the upper end of the upper protective shell are both provided with through holes.

[0010] Furthermore, the probes of the temperature sensor A, the water volume sensor, and the temperature sensor B can all pass through the through hole of the lower end of the lower protective shell and can be screwed to the internal thread of the lower protective shell.

[0011] Furthermore, the controller is also electrically connected to a display for displaying monitoring data.

[0012] Furthermore, the outer side of the middle portion of the lower protective shell is in the shape of a hexagonal prism.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a temperature sensor A and a water volume sensor, which can monitor the water temperature and water volume of the engine cooling water tank in real time and display them on the display. If the water temperature is higher than the set value or the water volume is less than the set amount, the display will also alarm to facilitate the operator to check, thereby reducing the engine failure of the stubble tiller.

[0015] 2. The temperature sensor B of the present invention monitors the temperature of the lubricating oil flowing in the gear transmission mechanism and displays it on the display. If the temperature sensor B detects that the temperature of the lubricating oil in the gear transmission mechanism is higher than the set value, the display can alarm to remind the operator. The operator can check whether the lubricating oil circulation pump installed on the engine or the engine cooling fan is faulty, causing the lubricating oil temperature to rise, and thus repair and eliminate the fault.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 A stubble tiller control and monitoring device includes a power supply 1, a display 2, and a controller 3. The power supply 1 and the display 2 are electrically connected to the controller 3. The controller 3 is electrically connected to a temperature sensor A4, a water level sensor 5, and a temperature sensor B6, respectively. The temperature sensor A4 and the water level sensor 5 are mounted on a cooling water tank 7 of an engine 9 to detect the temperature and water level of the coolant. The temperature sensor B6 is mounted on a gear transmission mechanism 8 to monitor the temperature of the circulating lubricating oil inside the gear transmission mechanism 8.

[0023] It should be noted that there are many meshing gears in the gear transmission mechanism 8. When the stubble tiller is working, these gears rotate at high speed and bear large torque. Therefore, the lubricating oil inside the gear transmission mechanism 8 is circulated through the oil pump and cooled by the engine cooling fan.

[0024] The controller 3 is electrically connected to a reduction motor 10 that controls the throttle of the engine 9 through a pull wire, and the controller 3 is electrically connected to a starter 11 installed on the engine for starting the engine 9 .

[0025] It should be noted that: since the stubble tiller is equipped with an engine separately and is connected to the rear of the tractor, the throttle of the stubble tiller is connected to the output shaft of the reduction motor 10 located in the tractor cab through a pull wire, and the reduction motor 10 drives the pull wire to control the throttle of the engine 9.

[0026] The controller 3 is electrically connected to a camera 12 installed on the stubble tiller.

[0027] By installing the camera 9, the working status of the stubble tiller can be viewed on the display in real time.

[0028] Among them, the temperature sensor A4, the water volume sensor 5 and the temperature sensor B6 are all installed with a protective device 13, which includes a lower protective shell 1301 and an upper protective shell 1302. The outer side of the lower end of the lower protective shell 1301 is provided with an external thread, and the inner and outer sides of the upper end of the lower protective shell 1301 are provided with threads. The outer side of the lower end of the upper protective shell 1302 is provided with an external thread that is compatible with the internal thread of the lower protective shell 1301, and the lower end of the lower protective shell 1301 and the upper end of the upper protective shell 1302 are both provided with a through hole 1303.

[0029] It should be noted that: since the stubble tiller works in a field in a harsh environment, installing a protective device on the temperature sensor A4 and the temperature sensor B6 can protect them.

[0030] Among them, the probes of the temperature sensor A4, the water volume sensor 5, and the temperature sensor B6 can all pass through the through hole 1303 at the lower end of the lower protective shell 1301, and can be screwed to the internal thread of the lower protective shell 1301.

[0031] The controller 3 is also electrically connected to a display 2 for displaying monitoring data.

[0032] The outer side of the middle portion of the lower protective shell 1301 is in the shape of a hexagonal prism.

[0033] It should be noted that the outer side of the middle portion of the lower protective shell 1101 is in the shape of a hexagonal prism, which makes it easy to disassemble the lower protective shell 1101 with a wrench.

[0034] Working principle: Before working, the stubble tiller is connected to the rear of the tractor. During working, the starter 11 is rotated by operating the operation controller 3. The rotation of the starter 11 can start the engine 9 installed on the stubble tiller, and then the tractor pulls the stubble tiller to work in the farmland. During the operation, the controller 3 controls the output shaft of the reduction motor 10 to rotate to drive the pull wire to control the throttle of the engine 9 to the appropriate position. During the movement of the stubble tiller, the temperature sensor A4 and the water volume sensor 5 can monitor the water temperature and water volume of the engine cooling water tank 7 in real time and display them on the display 2. At the same time, if the water temperature is higher than the set value or the water volume is less than the set amount, the display 2 will also alarm to facilitate the operator to check.

[0035] During operation, temperature sensor B6 monitors the temperature of the lubricating oil flowing within gear transmission mechanism 8 and displays it on display 2. If temperature sensor B6 detects that the lubricating oil temperature within gear transmission mechanism 8 is higher than a set value, display 2 will alarm the operator, who can then check whether the lubricating oil circulation pump or engine cooling fan installed on the engine is malfunctioning, causing the lubricating oil temperature to rise. This can then be repaired and corrected. During operation, camera 12 also displays the working conditions of the stubble tiller and its surroundings on display 2 in real time for the operator to view.

[0036] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
