DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 4 As shown, a seed box replenishing device provided by the present invention comprises a replenishing device body 100, a seed delivery tube 200 connected to the lower end of the replenishing device body 100, and a swing device connected to the seed delivery tube 200;

[0029] The swing device causes the seed transport tube 200 to swing repeatedly so that the seed transport tube 200 transports seeds to a plurality of seed boxes 300 .

[0030] In some embodiments, the replenishing device body 100 can be loaded with seeds, and the seed tube 200 of the replenishing device body 100 swings repeatedly under the action of the swing device; the outlet of the seed tube 200 is located above the seed box 300, and when the seeds flow out of the seed tube 200, they flow into the seed box 300.

[0031] Since the seed delivery tube 200 can swing repeatedly and move on multiple seed boxes 300, one seed delivery tube 200 can supply the seeds in the supply device body 100 to multiple different seed boxes 300, thereby achieving instant replenishment of the consumed seeds in the seed boxes 300, allowing the seed drill with the seed boxes 300 to sow farther.

[0032] Generally, seeds are added to the seeder on the flat ground at the edge of the farmland, i.e. the edge of the field; the sowing distance of the seeder is at least greater than twice the length of the field, thereby achieving the addition of seeds at the edge of the field.

[0033] The seed replenishing device increases the sowing distance of the seeder, so that a large length of farmland can be sown at least once, thereby avoiding adding seeds at other positions of the farmland, increasing the labor intensity of farmers, and reducing the efficiency of sowing.

[0034] The replenishing device body 100 of the seed box replenishing device provided by the present invention can store a large number of seeds, and the seed delivery tube 200 is used to transport the seeds in the replenishing device body 100; and under the action of the swing device, the seed delivery tube 200 is repeatedly swung, so that the seed delivery tube 200 can transport the seeds to multiple seed boxes 300, thereby realizing reseeding to the seed boxes 300, so that the direct seeding machine has better endurance, enabling it to travel back and forth between the seeding locations, thereby improving the sowing efficiency.

[0035] like Figure 2 As shown, based on the above embodiment, further, the swing device includes a push rod motor 400 and a fixed frame 500, the fixed frame 500 is mounted on the seed tube 200, and the driving rod of the push rod motor 400 is connected to the fixed frame 500, so that the seed tube 200 swings under the action of the push rod motor 400.

[0036] The push rod motor 400 has a driving rod, and the push rod motor 400 can extend and retract the driving rod. Since the driving rod is connected to the fixing frame 500 mounted on the seed tube 200, the pushing motor can make the seed tube 200 swing repeatedly driven by the driving rod, so that the outlet of the seed tube 200 can be switched to the openings on multiple seed boxes 300, thereby realizing the use of the seed tube 200 to transport the seeds in the replenishing device main body 100 to multiple seed boxes 300, thereby realizing one seed tube 200 to replenish multiple seed boxes 300.

[0037] In order to limit the moving range of the seed delivery tube 200 and make the seed delivery tube 200 move within the limited range, the swing device further includes a limiting guide groove 700, and the lower end of the fixed frame 500 is provided with a guide wheel 600 that cooperates with the limiting guide groove 700, and the limiting guide groove 700 is used to limit the movement trajectory of the guide wheel 600.

[0038] For example, a seed tube 200 can supply seeds to five seed boxes 300. A guide wheel 600 is provided on the fixed frame 500 of the seed tube 200. The guide wheel 600 is located in a guide groove. Within the moving range of the seed tube 200, the seed tube 200 can supply seeds to five seed boxes 300. The guide groove limits the moving trajectory of the guide wheel 600, so that the seed tube 200 moves repeatedly within the range of supplying seeds to the five seed boxes 300.

[0039] like Figure 1 As shown, based on the above embodiment, it further includes a base 800 and a support frame 900, and the replenishing device body 100 is arranged on the base 800 through the support frame 900.

[0040] A support frame 900 is arranged on the base 800, and the supply device body 100 is arranged on the support frame 900. Generally, the base 800 is used to be fixed on a seeder, and the supply device body 100 is arranged on the support frame 900 so that the supply device body 100 has a certain height, so that the seeds in the supply device body 100 can flow downward due to their own gravity, and finally flow into the seed box 300 through the seed transport tube 200.

[0041] Based on the above embodiment, further, the seed delivery pipe 200 includes a lower connecting pipe 202 for connecting to the replenishing device body 100 and a seed delivery main pipe 201 rotatably connected to the lower connecting pipe 202 , and the fixing frame 500 is sleeved on the seed delivery main pipe 201 .

[0042] The lower connecting tube 202 of the seed transport tube 200 is used to be fixedly connected to the replenishing device body 100. The seeds in the replenishing device body 100 enter the seed transport tube 200 through the lower connecting tube 202. The main seed transport tube 201 and the lower connecting tube 202 are rotatably connected, that is, the main seed transport tube 201 and the lower connecting tube 202 are sleeved, and the connection between the main seed transport tube 201 and the lower connecting tube 202 can rotate. When the lower connecting tube 202 is fixedly connected to the replenishing device body 100, the main seed transport tube 201 can also rotate, thereby realizing the swing of the main seed transport tube 201.

[0043] The connection between the seed transport main pipe 201 and the lower connecting pipe 202 is located on the same straight line. The seed transport main pipe 201 has a bend, which makes the seed transport main pipe 201 face the seed box 300. The relative rotation between the bent upper end of the seed transport main pipe 201 and the lower connecting pipe 202 causes the bent lower end of the seed transport main pipe 201 to swing.

[0044] Based on the above embodiment, further, the replenishing device body 100 has a cavity 101 for accommodating seeds, an opening for loading seeds into the cavity 101, and at least one seed delivery device located at the lower end of the cavity 101 for delivering the seeds in the cavity 101 to a seed delivery tube 200; a covering plate 102 for sealing the cavity 101 is provided on the opening.

[0045] In some embodiments, the replenishing device body 100 has a cavity 101, and seeds are loaded into the replenishing device body 100 from the opening of the cavity 101. In order to prevent foreign matter from entering and prevent seeds from flowing out of the cavity 101, a covering plate 102 is provided at the opening of the cavity 101.

[0046] like Figure 2 As shown, based on the above-mentioned embodiment, the seed transport device further includes a seed transport guide tube 110 respectively connected to the cavity 101 and the seed transport tube 200, an outer groove wheel 160 for transporting seeds in the cavity 101 to the seed transport tube 200, and a transmission wheel 130 located outside the seed transport guide tube 110 and connected to the outer groove wheel 160; the transmission wheel 130 rotates synchronously with the outer groove wheel 160.

[0047] like Figure 3 and Figure 4 As shown, further, a guide plate 120 is provided in the seed transport guide tube 110 , and the guide plate 120 is used to guide the seeds flowing from the cavity 101 to the outer groove wheel 160 in the seed transport guide tube 110 .

[0048] The seed transport guide tube 110 of the seed transport device is connected between the cavity 101 and the seed transport tube 200 . The seeds in the cavity 101 flow into the seed transport tube 200 through the seed transport guide tube 110 , and finally flow into the seed box 300 .

[0049] The seed transport guide tube 110 has an outer groove wheel 160. As the outer groove wheel 160 rotates, the seeds at the upper end of the outer groove wheel 160 flow to the lower end of the outer groove wheel 160 through the outer groove wheel 160. In order to make the seeds in the cavity 101 of the replenishing device body 100 flow to the outer groove wheel 160, a guide plate 120 is provided at the upper end of the outer wheel groove. Generally, there are two guide plates 120. When the seeds flow to the guide plates 120, the two guide plates 120 guide the seeds to the middle, so that the seeds flow to the groove at the upper end of the outer groove wheel 160, and also avoid the seeds from flowing out from the gap between the outer groove wheel 160 and the inner wall of the seed transport guide tube 110, ensuring that the seeds can only enter the seed transport tube 200 through the transportation of the outer groove wheel 160.

[0050] The seed delivery guide tube 110 and the seed delivery tube 200 are generally connected via a flange, and the seed delivery tube 200 and the seed delivery guide tube 110 connected via a flange are convenient for disassembly and maintenance.

[0051] Furthermore, a driving motor 140 is included, and a driving wheel 150 of the driving motor 140 is connected to the transmission wheel 130 to rotate the outer groove wheel 160 .

[0052] The driving wheel 150 of the driving motor 140 is connected to the transmission wheel 130. Generally, the driving wheel 150 and the transmission wheel 130 are connected by a chain or a belt. The driving motor 140 drives the driving wheel 150 to rotate, so that the transmission wheel 130 drives the outer groove wheel 160 to rotate, and then the seeds on the upper end of the outer groove wheel 160 are transported to the seed delivery tube 200; that is, the driving motor 140 controls whether the supply device body 100 supplies seeds to the seed box 300, and the push rod motor 400 controls which seed box 300 the seed delivery tube 200 supplies seeds to.

[0053] Furthermore, it also includes a control system and a plurality of detection devices, wherein the detection device is used to detect the height of the seeds in the seed box 300; the control system is used to control the swing device and the seed feeding device;

[0054] When the detection device detects that the height of seeds in a certain box 300 is lower than a preset height, the detection device sends the detection information to the control system, and the control system controls the swing device to swing the seed delivery tube 200 onto the seed box 300 and start the seed delivery device to reseed the seed box 300.

[0055] In some embodiments, the detection device is generally an ultrasonic ranging module, and a detection device is provided on each seed box 300; as the sowing process proceeds, the seed amount gradually decreases and the measured distance gradually increases. When the set value is reached, the detection device sends a signal to the control system, and the control system controls the swing device to move the seed delivery tube 200 to the seed box 300 corresponding to the detection device and controls the seed delivery device to replant the seed box 300. When the seed delivery device continues for a predetermined time, the control system controls the seed delivery device to stop replanting.

[0056] Other methods may also be used, for example, as the amount of seeds increases, the measured distance gradually decreases. When the set value is reached, the detection device sends a signal to the control system, and the control system controls the seed transport device to stop reseeding.

[0057] When adding seeds to the seed boxes 300, due to various objective reasons, it is not possible to ensure that the seed amounts in each seed box 300 are consistent; during the sowing process, the sowing amount of each seed meter is not completely consistent; as a result, when one seed box 300 is out of seeds, there are still a lot of seeds left in other seed boxes 300.

[0058] By arranging a detection device in the seed box 300 to detect the seed quantity in the seed box 300 in real time, when a seed box 300 lacks seeds, the detection device in the seed box 300 sends a signal to the control system, which is generally a single-chip microcomputer. The control system controls the extension and retraction length of the driving rod of the push rod motor 400 according to the signal of the detection device. The multiple detection devices respectively correspond to the extension length of the driving rod by the push rod motor 400. When the push rod motor 400 extends the driving rod to the length corresponding to the detection device, the seed delivery tube 200 is just located above the seed box 300, and the seed delivery device is controlled to start replanting. Generally, after the control system receives the signal sent by the detection device, it delays driving the seed delivery device for 3 seconds so that the swing device has enough time to move the seed delivery tube 200 to the seed box 300. The control system controls the opening time of the seed delivery device. When the seed delivery device replants the seed box 300 for a preset time, the control system stops the replanting of the seed delivery device and resets the swing device, that is, the push rod motor 400 restores the driving rod to its initial state.

[0059] The present invention also provides a direct seeding machine, comprising the seed box replenishing device described above.

[0060] like Figure 5 As shown, the base 800 of the seed box replenishing device can be fixed on the overall structure of the 2BDXZ-10SC type rice direct seeding machine, and the seed box replenishing device can also be applied to other direct seeding machines.

[0061] When used in a 2BDXZ-10SC rice direct seeding machine, the lower end of the seed box replenishing device is provided with two seed delivery devices, each of which is connected to a seed delivery tube 200 , and each seed delivery tube 200 is responsible for reseeding five seed boxes 300 .

[0062] The direct seeding machine provided by the present invention has such a seed box replenishing device, which can move with the direct seeding machine and can replenish seeds into the seed box 300 at any time after the seeds in the direct seeding machine are consumed, so that the direct seeding machine can sow at a longer distance, thereby reducing the number of times the seed is added to the direct seeding machine and improving the efficiency of sowing.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
