Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an electric drive fertilizing and sowing multi-mode device. Background Art

[0002] A seeder is a device used for sowing seeds.

[0003] The existing seeder has the following deficiencies when in use:

[0004] For the existing mechanical seeder, the ground wheel rotates to drive the chain, and the chain passes through a series of gear combinations to adjust to the target speed, while driving the fertilizing and sowing of seeds and fertilizers at the same time. Because of the existence of seeds and fertilizers, the load of the ground wheel rotation is greatly increased, and the ground wheel is prone to stall with the vehicle speed during the high-speed rotation process, resulting in uneven fertilizing and sowing, affecting the income of farmers. Moreover, there are some electric drive fertilizing systems or electric drive sowing systems on the market. Often, multiple systems are required to meet the needs of fertilizing and sowing at the same time. When multiple systems are used, some parts are reused, resulting in an increase in the cost of multiple systems, repeated operations, and increased difficulty for users. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies in the prior art that for the existing mechanical seeder, the ground wheel rotates to drive the chain, and the chain passes through a series of gear combinations to adjust to the target speed, while driving the fertilizing and sowing of seeds and fertilizers at the same time. Because of the existence of seeds and fertilizers, the load of the ground wheel rotation is greatly increased, and the ground wheel is prone to stall with the vehicle speed during the high-speed rotation process, resulting in uneven fertilizing and sowing, affecting the income of farmers. Moreover, there are some electric drive fertilizing systems or electric drive sowing systems on the market. Often, multiple systems are required to meet the needs of fertilizing and sowing at the same time. When multiple systems are used, some parts are reused, resulting in an increase in the cost of multiple systems, repeated operations, and increased difficulty for users, and an electric drive fertilizing and sowing multi-mode device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Electric drive fertilization and seeding multi-mode device, including a machine body and a tractor, characterized in that two first fixing plates are fixedly arranged on one side of the bottom of the machine body, two second fixing plates are fixedly arranged on one side of the bottom of the machine body, frames are fixedly arranged at the bottoms of the second fixing plates and the first fixing plates, the same ground wheel is rotatably connected to the inner walls on both sides of the frame, a bracket is fixedly arranged on the top of the machine body, a fertilizer tank for storing liquid fertilizer is fixedly arranged on the top of the bracket, a peristaltic pump is fixedly arranged on the top of the machine body, a first motor for driving the peristaltic pump to operate is fixedly arranged on the top of the machine body, the output end of the first motor is fixedly connected to the output shaft of the peristaltic pump, a display and a controller for controlling the first motor are fixedly arranged in the cab of the tractor, a seed box is fixedly arranged on the top of the machine body, a feeding hopper is fixedly arranged on the top of the seed box, the bottom end of the seed box penetrates through the top of the machine body, and a seed metering device for discharging seeds is fixedly arranged at the bottom end of the seed box;

[0008] A rotational speed detection mechanism, which is arranged on the frame for detecting the rotational speed of the ground wheel;

[0009] A seed metering mechanism, which is arranged on the seed metering device for discharging seeds.

[0010] In a possible design, the rotational speed detection structure includes a rotational speed acquisition sensor and a rotational speed induction block. One side of the rotational speed acquisition sensor is fixedly connected to the inner wall of one side of the frame, one side of the rotational speed induction block is fixedly connected to one side of the ground wheel, and the rotational speed acquisition sensor and the rotational speed induction block are matched with each other.

[0011] In a possible design, the seed metering mechanism includes a second motor and a seed metering disc. One side of the second motor is fixedly connected to one side of the seed metering device, one side of the seed metering disc is rotatably connected to the inner wall of one side of the seed metering device, the output end of the second motor penetrates through one side of the seed metering device and is fixedly connected to one side of the seed metering disc, a seed metering pipe is fixedly arranged at the bottom of the seed metering device, and a seed dropping sensor for detecting seeds is fixedly arranged at the bottom end of the seed metering pipe.

[0012] In a possible design, an input pipe is fixedly arranged at the input port of the peristaltic pump. One end of the input pipe is fixedly connected to and communicated with one side of the fertilizer tank. An output pipe is fixedly arranged at the output port of the peristaltic pump. One end of the output pipe penetrates through the top of the machine body, and a fertilization sensor is installed on the output pipe.

[0013] In a possible design, a pulling plate for facilitating the traction and movement of an external driving machine is fixedly arranged on one side of the machine body.

[0014] In a possible design, an adding pipe for facilitating the addition of fertilizer is fixedly arranged on the top of the fertilizer tank, and a cover body is threadedly connected to the adding pipe.

[0015] In a possible design, a warning horn for giving warnings is fixedly arranged in the cab of the tractor.

[0016] In this application, the first motor, the controller, the second motor, the peristaltic pump, the warning horn and the display are electrically connected to each other. When in use, the tractor and the towing plate are connected, which can be connected by bolts or by a pull rope. The ground wheel is towed by the driving machine (tractor), and the ground wheel rotates. The rotation speed induction block on the ground wheel rotates synchronously with the ground wheel. The rotation speed acquisition sensor collects the rotation speed of the rotation speed induction block in real time and feeds it back to the display. The display controls the first motor for fertilizing and the second motor for sowing to rotate at different rotation speeds through an internal program signal. The first motor drives the peristaltic pump (the rotation of the output end of the first motor drives the operation of the peristaltic pump, thereby generating suction and discharging the liquid fertilizer in the fertilizer tank through the input pipe and the output pipe). The second motor drives the seed discharging disc in the seed metering device to work (the rotation of the output end of the second motor drives the rotation of the seed discharging disc, and the rotation of the seed discharging disc drives the rotation of the seeds coming down from the seed box. After the seed discharging disc rotates 90 degrees, the seeds are discharged through the seed discharging pipe). The rotation speed of the first motor increases as the vehicle speed increases to ensure that the fertilizing amount per unit time is directly proportional to the vehicle speed. The rotation speed of the second motor increases as the vehicle speed increases to ensure that the distance between seeds remains unchanged.

[0017] During the fertilizer application process, the amount of fertilizer is monitored by a fertilizer application sensor and fed back to the display in real time. The fertilizer application sensor monitors the presence, absence and blockage of the fertilizer and gives a prompt to the user through the warning horn. After the user gets the prompt, the user eliminates the fault.

[0018] During the sowing process, the seed dropping is monitored by a seed dropping sensor and fed back to the display in real time. The seed dropping sensor monitors the single-seed, double-seed and missed-seed conditions of the seeds and gives a prompt to the user through the horn. After the user gets the prompt, the user eliminates the fault (the seeds for sowing can be granular seeds such as corn, soybean, sorghum, sugar beet, sesame, etc.).

[0019] Principle of motor rotation speed control: The ground wheel rotation speed sensor collects the ground wheel rotation speed, converts it into an electrical signal and sends it to the display. The display converts the signal into a controller speed signal through an internal algorithm. The controller receives the signal and adjusts the motor voltage or frequency to adjust the motor rotation speed.

[0020] After sowing and fertilizing are achieved through electric drive, the load on the ground wheel is greatly reduced, so that the ground wheel can be synchronized with the vehicle speed during the speed following process, and then the vehicle speed acquisition is synchronized, especially when the soil is moist and the ground wheel slips or jams under heavy load, causing the seeder to be unable to operate. The use of this system (especially the use of millimeter-wave radar as the source of vehicle speed acquisition signals) can operate around the clock, increase operating time, increase equipment utilization, and provide a basis for operators to increase their income. The synchronous acquisition of vehicle speed is used as the signal input of the first motor and the second motor to ensure the synchronization of the first motor and the second motor, ensure the accuracy of fertilization and sowing, increase the amount of fertilizer and sowing rate of crops, and thus increase the income from farming.

[0021] The vehicle speed is collected and input into the system through a vehicle speed collection system. The system converts the signal through an algorithm and outputs it to the controller. The motor can drive one or more fertilizer boxes or peristaltic pumps, and can drive one or more seed meters, which can simplify the complexity of the system and save costs. It can also simplify the operation, simplifying the control of the fertilization system and the seeding system together to reduce the difficulty of operation for the operator. During the operation, through visual monitoring and auditory monitoring, fertilization faults and seeding faults can be discovered in time, providing a basis for the operator to troubleshoot in time and improve the seeding quality.

[0022] The beneficial effects of the present invention are:

[0023] In the utility model, the electric-driven fertilization and sowing multi-mode device uses a speed detection mechanism, and the speed sensing block on the ground wheel rotates synchronously with the ground wheel. The speed acquisition sensor collects the speed of the speed sensing block in real time, thereby detecting the speed of the ground wheel;

[0024] In the utility model, the electric-driven fertilization and sowing multi-mode device, through the seeding mechanism, the rotation of the second motor output end drives the rotation of the seeding disc, and the rotation of the seeding disc drives the rotation of the seeds coming down from the seed box. After the seeding disc rotates ninety degrees, the seeds are discharged through the seeding tube;

[0025] In the utility model, after sowing and fertilizing are achieved by electric drive, the load of the ground wheel is greatly reduced, so that the ground wheel can be synchronized with the vehicle speed during the speed following process, and then the vehicle speed collection is synchronized, ensuring the accuracy of fertilization and sowing, increasing the fertilizer application and sowing rate of crops, and thus increasing the income from farming.
