Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, and specifically relates to a seeder hopper with an excess material warning device. Background Technology

[0002] In agricultural seeding operations, monitoring the remaining seed in the seeder hopper directly affects seeding efficiency and continuity. Currently, because the seeding nozzle of existing seeders is usually inserted into the soil, workers cannot directly observe the amount of seed remaining in the hopper. This easily leads to the phenomenon of "empty seeding"—seeding continues even after the seed in the hopper is depleted, resulting in uneven seeding or missed seeding.

[0003] Although existing technologies all include sensors for residual monitoring, the vibration of the seeder during field operations can affect the stability of the detection, causing fluctuations or misjudgments. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing a seeder hopper with a residual material warning device. The specific technical solution is as follows:

[0005] The seeder hopper with a residual material warning device includes the following components connected in sequence along the vertical direction:

[0006] The hopper body has a feeding port at the top and a discharge port at the bottom, with a buzzer and indicator light installed on the top edge;

[0007] The transmission connection frame is connected around the outside of the hopper body;

[0008] The weighing assembly includes at least three sets of L-shaped load cells. The horizontal section of the load cell is fixed to the end face of the support base, and the vertical section is embedded in the connecting groove at the bottom of the conductive connecting frame. The detection surface is perpendicular to the ground.

[0009] The support base has a control module installed on the side. There is a gap between the support base and the transmission connection frame, and the gap is filled with a buffer material to absorb the vertical vibration of the hopper body.

[0010] The control module receives the pressure signal from the weighing sensor and triggers a buzzer and indicator light alarm when the weight of the remaining material is lower than the threshold.

[0011] As a further technical solution of this utility model, the number of weighing sensors is at least three sets, which are evenly distributed around the connection surface of the conductive connecting frame and the support base.

[0012] As a further technical solution of this utility model, the buffer filler is an elastic polymer material, which is filled in the gap between the conductive connecting frame and the support base, and the compression deformation direction is consistent with the sensitive axis of the weighing sensor.

[0013] As a further technical solution of this utility model, the inner side of the transmission connecting frame is connected to the hopper body through a connector and a reserved gap is formed to accommodate the expansion deformation of the hopper body.

[0014] As a further technical solution of this utility model, the control module is connected to the weighing sensor, the buzzer and the indicator light respectively via cables.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) In this application, the weight change of the hopper body is transmitted to the weighing sensor through the combined design of the transmission connection frame and the weighing component. Combined with the signal processing of the control module, the weight of the remaining material can be measured in real time and accurately. Furthermore, the detection surface of the weighing sensor is perpendicular to the ground. With the help of the buffer filling material, the influence of vertical vibration during the operation of the seeder on the detection results can be effectively filtered.

[0017] (2) In this application, a connecting piece and a reserved gap are provided between the transmission connecting frame and the hopper body to avoid interference from lateral force caused by material expansion or thermal deformation, and to ensure the measurement accuracy of the weighing sensor.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Figure 1A schematic diagram of the overall structure of the seeder hopper with an excess material warning device is shown. Figure 2 An exploded structural diagram of a seeder hopper with a residual material warning device is shown. Figure 1 and Figure 2 The seeder hopper with residual material warning device includes a hopper body 100, a transmission connecting frame 200, a weighing component 300, and a support base 400 connected in sequence along the vertical direction. The transmission connecting frame 200 is connected around the outside of the hopper body 100 to transmit the weight of the hopper body 100 to the weighing component 300. The weighing component 300 is connected between the transmission connecting frame 200 and the support base 400 to measure the weight of residual material in the hopper body 100. The support base 400 can be installed on the frame of the seeder to support the entire hopper device.

[0026] Figure 3 A schematic diagram of the structure of the hopper body 100 is shown; Figure 3 In the hopper body 100, the top has a feeding port 101 for feeding material into the hopper body 100, and the bottom has a discharge port 102. During installation, the discharge port 102 is connected to the seed delivery pipe for sowing. A buzzer 110 and an indicator light 120 are installed on the top edge of the hopper body 100 to issue an alarm when the remaining material is insufficient, so as to replenish the material into the hopper body 100 in time. The buzzer 110 is set to sound continuously, and the indicator light 120 is set to stay on.

[0027] Figure 4 A schematic diagram of the connection structure of the conduction connection frame 200, the weighing component 300, and the support base 400 is shown. Figure 4 In the process, the inner side of the transmission connecting frame 200 is connected to the hopper body 100 through the connector 220, forming a reserved gap 230 between them. Several sets of connectors 220 are provided and evenly distributed around the circumference. On the one hand, this ensures a stable connection between the transmission connecting frame 200 and the hopper body 100. On the other hand, the reserved gap 230 between the transmission connecting frame 200 and the hopper body 100 can prevent the hopper body 100 from squeezing the transmission connecting frame 200 when it expands due to material accumulation or thermal deformation, thus avoiding the lateral force generated by the hopper body 100 from affecting the measurement accuracy of the weighing component 300.

[0028] See also Figure 4The weighing assembly 300 includes at least three sets of load cells 310. These load cells 310 are evenly distributed around the connection surface between the conductive connecting frame 200 and the support base 400. Each load cell 310 has an L-shaped structure. The horizontal section is bolted to the end face of the support base 400. The bottom of the conductive connecting frame 200 has a corresponding connecting groove 210 for each load cell 310. The vertical section of each load cell 310 is embedded in the connecting groove 210, creating a gap between the conductive connecting frame 200 and the support base 400, filled with a buffer filler 420. The detection surface of the load cell 310 is perpendicular to the ground. The vertical section of the load cell 310 is rigidly connected to the conductive connecting frame 200. The system can accurately transmit force, ensuring the measurement accuracy of the load cell 310. The buffer filler 420 fills the contact surface between the transmission connecting frame 200 and the support base 400, absorbing the vertical vibration generated by the hopper body 100. When the detection surface is perpendicular to the ground, the load cell 310 is only sensitive to vertical loads. At the same time, during field operations, the vibration of the seeder is mainly vertical. The vertical detection surface makes the sensitive axis of the load cell 310 consistent with the main vibration direction. Combined with the energy absorption characteristics of the compression deformation of the buffer filler 420, it can filter the detection fluctuations caused by vibration, which is beneficial to the detection accuracy. The buffer filler 420 is an elastic polymer material, such as thermoplastic elastomer or traditional rubber.

[0029] See also Figure 4 A control module 410 is installed on the side of the support base 400. The control module 410 can trigger the buzzer 110 and the indicator light 120 based on the pressure signal received from the weighing sensor 310. That is, the weighing sensor 310, the buzzer 110 and the indicator light 120 are all connected to the control module 410 through cables to realize signal transmission. When the amount of residual material in the hopper body 100 is lower than the preset threshold, the weighing sensor 310 sends a pressure signal to the control module 410. The control module 410 can trigger the buzzer 110 to sound continuously and the indicator light 120 to light continuously based on the pressure signal to realize the alarm.
