[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] A rope-type vegetable seeder according to an embodiment of the present invention includes a frame 100, a sowing unit 200, a monitoring unit, a controller and an alarm. The sowing unit 200 includes a first disc 1 and a second disc 2, which are respectively mounted on the frame 100, and the first disc 1 and the second disc 2 are arranged relative to each other in the width direction of the frame 100. The first disc 1 and the second disc 2 are rotatable relative to the frame 100. The monitoring unit includes a first sensor and a second sensor. The first sensor is used to monitor the rotational speed of the first disc 1, and the second sensor is used to monitor the rotational speed of the second disc 2.

[0029] Specifically, if Figure 1As shown, the sowing unit 200 is located at the front side of the frame 100. A suspension frame is installed at the front end of the frame 100 for connecting to a traction device, for example, the traction device can be a tractor. The first and second discs 1 and 2 are mounted on the upper end of the frame 100. The first and second discs 1 and 2 are arranged opposite each other in the left-right direction. The first and second discs 1 and 2 have the same height, and the rotation axes of the first and second discs 1 and 2 extend in the front-to-back direction. The first sensor is located on the side of the frame 100 where the first disc 1 is mounted, and the second sensor is located on the side of the frame 100 where the second disc 2 is mounted. For example, the first and second sensors can be Hall sensors.

[0030] Controller and alarm, the controller is connected to the monitoring unit, the alarm is connected to the controller,

[0031] For example, the controller may be a single chip microcomputer, the alarm may be a buzzer, or the first sensor, the second sensor and the buzzer may be connected to different interfaces of the single chip microcomputer respectively.

[0032] It should be noted that the breaking of the seed rope is achieved by obtaining and comparing the rotational speeds of the first disc 1 and the second disc 2, and is a passive operation. After the seed rope is first manually guided and buried in the soil, the seed rope will drive the rotation of the seed disc under the traction of a tractor or other traction equipment, and will match the speed of the traction equipment. In other words, the greater the speed of the traction equipment, the greater the rotational speed of the first disc 1 and the second disc 2. The speed difference between the first disc 1 and the second disc 2 is limited, but if the seed rope on the first disc 1 or the second disc 2 breaks or the sowing is completed, the seed disc where the seed rope is located will reduce its speed due to the loss of guidance, but at this time the speed state of the other seed discs is still matched with the state of the traction device. Based on this characteristic, the seed disc rotation speed is measured by a Hall sensor and the measurement results are compared. If there is a large difference in speed between the seed discs, the buzzer alarm is triggered to remind the driver to check the seed rope status, thereby realizing the seed rope breaking alarm and improving the sowing quality.

[0033] In some embodiments, the monitoring unit further includes a magnetic sheet 3 installed on the first disk 1 and the second disk 2, the installation position of the magnetic sheet 3 on the first disk 1 corresponds to the first sensor, and the installation position of the magnetic sheet 3 on the second disk 2 corresponds to the second sensor.

[0034] Specifically, if Figure 2 As shown, multiple magnetic sheets 3 are installed on the first disk 1 and the second disk 2. For example, the number of magnetic sheets 3 can be four, and the four magnetic sheets 3 are distributed in a ring shape on the seed disk. The position of the magnetic sheet 3 corresponds to the position of the sensor. The magnetic sheet 3 rotates with the seed disk, and the seed disk rotation speed will be measured when passing through the Hall sensor.

[0035] In some embodiments, the sowing unit 200 further includes a first furrow opener 4 , and the number of the first furrow openers 4 is multiple, and the multiple first furrow openers 4 are arranged at intervals in the width direction of the frame 100 .

[0036] Specifically, if Figure 1 As shown, the first furrow opener 4 is installed at the lower end of the frame 100. There are four first furrow openers 4, and the four first furrow openers 4 are evenly spaced in the left and right directions. It should be noted that the number of the first furrow openers 4 is the same as the number of the seed discs.

[0037] In some embodiments, the first trench opener 4 includes a feed pipe 41 and a trenching portion 42. The feed pipe 41 extends in the up and down directions, and the interior of the feed pipe 41 is hollow. The trenching portion 42 is installed at the bottom of the feed pipe 41. In the direction of forward movement of the frame 100, the trenching portion 42 is located upstream of the feed pipe 41, and the trenching portion 42 has an arc transition section adjacent to one side of the feed pipe 41.

[0038] Specifically, if Figure 3 As shown, the interior of the feed pipe 41 is hollow, and the feed pipe 41 extends in the up and down directions. The seed rope passes through the feed pipe 41 from top to bottom. The outlet of the feed pipe 41 is located behind the groove portion 42. The connection between the inner side of the groove portion 42 and the outlet of the feed pipe 41 is an arc transition section, which can reduce the friction between the seed rope and the groove portion 42 and reduce the risk of the seed rope breaking.

[0039] In some embodiments, the height of the groove portion 42 on the feed pipe 41 is adjustable.

[0040] Specifically, if Figure 3 As shown, a mounting frame is provided at the lower end of the feed pipe 41, and a plurality of holes are distributed on the mounting frame in the up and down directions. The pin passes through the holes to connect the groove portion 42 to the mounting frame. Holes of different heights can be selected according to the sowing depth, thereby achieving fine-tuning of the sowing depth to a certain extent.

[0041] In some embodiments, the sowing unit 200 also includes a plurality of first soil covering devices 5 and a first pressing roller 6. The first soil covering devices 5 are installed at the bottom of the feed pipe 41. In the forward direction of the frame 100, the first soil covering devices 5 are located downstream of the feed pipe 41. The plurality of first soil covering devices 5 correspond one-to-one to the plurality of first furrow openers 4. In the forward direction of the frame 100, the first pressing roller 6 is located downstream of the first furrow opener 4. The first pressing roller 6 extends along the width direction of the frame 100.

[0042] Specifically, if Figure 1 and Figure 3As shown, the first soil covering device 5 is installed at the rear end of the conveying pipe 41. The first soil covering device 5 is generally L-shaped. The front end of the first soil covering device 5 is installed on the mounting frame at the bottom of the conveying pipe 41. The rear end of the first soil covering device 5 is in contact with the ground, covering the soil onto the seed rope sown into the ground.

[0043] The first pressing roller 6 extends in the left-right direction, and the left and right ends of the first pressing roller 6 are respectively connected to the frame 100, and the first pressing roller 6 is rotatable relative to the frame 100. The outer surface of the first pressing roller 6 is in contact with the ground. The first pressing roller 6 can slightly compact the ground to prevent the seed rope from being exposed to the ground, thereby improving the quality of sowing.

[0044] In some embodiments, a rope-type vegetable seeder also includes a drip tape laying unit 300. In the direction of forward movement of the frame 100, the drip tape laying unit 300 is located downstream of the sowing unit 200. The drip tape laying unit 300 includes a belt reel 7 and a second furrow opener 8. The belt reel 7 is connected to the frame 100, and the belt reel 7 is rotatable relative to the frame 100. The second furrow opener 8 is connected to the frame 100, and the second furrow opener 8 is between two adjacent first furrow openers 4.

[0045] Specifically, if Figure 1 As shown, the drip irrigation tape laying unit 300 is located behind the sowing unit 200. The tape reel 7 is mounted on the upper end of the frame 100. The rotating shaft of the tape reel 7 extends in the left-right direction and the tape reel 7 can rotate relative to the frame 100. The second furrow opener 8 is mounted on the lower end of the frame 100 and is located between two adjacent first furrow openers 4. In other words, the drip irrigation tape is laid between two sowing rows.

[0046] In some embodiments, the drip tape laying unit 300 also includes a tensioning assembly 9, which includes a tensioning frame 91 and a tensioning roller 92. The tensioning frame 91 is installed on the frame 100, and the tensioning roller 92 is connected to the tensioning frame 91. The tensioning roller 92 is rotatable relative to the tensioning frame 91, and the tensioning roller 92 extends along the width direction of the frame 100.

[0047] Specifically, if Figure 1 As shown, the tensioning frame 91 is installed on the frame 100, and the tensioning roller 92 is installed at the rear end of the tensioning frame 91. The tensioning roller 92 extends in the left and right directions, and the position of the tensioning roller 92 in the front and rear directions is adjustable, and the tightening rod is rotatable relative to the tensioning frame 91. There is a gap between the tensioning roller 92 and the tensioning frame 91 to form a channel, and the drip irrigation belt passes through the channel. The tensioning roller 92 is used to smooth the drip irrigation belt, and because the tensioning frame 91 is away from the belt reel 7, when the drip irrigation belt passes through the tensioning roller 92, the tensioning roller 92 will apply a part of the pulling force to the drip irrigation belt to prevent the drip irrigation belt from curling.

[0048] In some embodiments, the rope-type vegetable planter further includes a fertilizer application unit 400 . In the direction in which the frame 100 moves forward, the fertilizer application unit 400 is located downstream of the drip tape laying unit 300 .
