The towing arm 14 is connected with a tractor, and the vehicle body 1 travels and sows seeds under the driving of the tractor.

[0026] Further, referring to Figure 1 and 3 , in order to ensure that the seeds are more smooth in the transmission process and are not blocked, the unequal distance spiral separation transmission assembly 41 comprises a transmission sleeve 410, a transmission rod 411 and unequal distance spiral blades 412 arranged in the transmission sleeve 410. An inlet is arranged on the top of one end of the transmission sleeve 410, and the inlet is communicated with the outlet of the seed storage mechanism through the first flexible connecting pipe 3. An outlet is arranged on the bottom of the other end of the transmission sleeve 410, and the outlet is communicated with the inlet of the seed metering mechanism through the second connecting pipe 5. One end of the transmission rod 411 penetrates through the transmission sleeve 410 and is fixedly connected with the output end of the transmission motor 40. The unequal distance spiral blades 412 are fixedly arranged on the transmission rod 411, and the distance between adjacent unequal distance spiral blades 412 gradually increases along the transmission direction.

[0027] In the embodiment, first flange type bearing seats 413 are arranged on the two ends of the transmission sleeve 410 respectively, and the transmission rod 411 is sleeved in the first flange type bearing seats 413 respectively. When the transmission rod 411 is driven to rotate by the transmission motor 40, the transmission rod 411 can rotate more stably.

[0028] In the embodiment, since the distance between adjacent unequal-pitch spiral vanes 412 gradually increases along the conveying direction, the seeds in the state of dense distribution when falling into the inlet are conveyed to the state of sparse distribution and grain separation when reaching the outlet, and enter the seed metering mechanism in the state of grain separation, solving the problem of blockage in the seed conveying process, realizing smooth conveying of the seeds, and laying a foundation for uniform seed metering in the seed metering mechanism.

[0029] Further, please refer to Figure 1 、 4 , 5, in order to ensure that the seeds can be uniformly and smoothly metered during the seed metering process, the seed metering mechanism comprises a seed metering assembly 60, a transmission assembly 61 and a control assembly.

[0030] The seed metering assembly 60 comprises a disc sleeve 600, a seed guide pipe 601 and a seed metering disc 602. The disc sleeve 600 is arranged below the unequal-pitch spiral separation and conveying assembly 41 and is fixedly connected with the vehicle body 1. An inlet is formed on the upper end surface edge of the disc sleeve 600, which is communicated with the outlet of the conveying sleeve 410 through the second connecting pipe 5. An outlet is formed on the lower end surface edge of the disc sleeve 600, which is communicated with the inlet of the seed guide pipe 601. The outlet position of the seed guide pipe 601 is matched with the cultivation mechanism, which is used for guiding the seeds into the seed holes. The seed metering disc 602 is arranged in the disc sleeve 600 and can be driven by the transmission assembly 61 to rotate unidirectionally relative to the disc sleeve 600. Under the control of the control assembly, the seed metering disc 602 cooperates with the unequal-pitch spiral separation and conveying mechanism to realize the gathering of the seeds in the slots. Through the gathering of the seeds in the slots by the seed metering mechanism, the device can gather the seeds according to the required number of seeds in each seed hole and further seed into the seed holes, realizing uniform seed sowing.

[0031] In the embodiment, the disc sleeve 600 is in the shape of a hollow flat cylinder and is enclosed by an upper disc cover 6000, a lower disc cover 6001 and a side disc body 6002. Through the cooperation of the transmission assembly 61 and the control assembly, the seed metering disc 602 can rotate unidirectionally in the disc sleeve 600, realizing the gathering of the seeds in the slots and further realizing uniform seed sowing.

[0032] Further, please refer to Figure 4 、 5and 6, in order to realize the seed in the seed plate 602 in the slot aggregation, ensure the uniformity of seed, seed plate 602, cylindrical; Seed plate 602 disc surface along the circumference is uniformly provided with several seed slots 6020, each seed slot 6020 is vertically through the seed plate 602; The position of seed slot 6020 matches the position of disc sleeve inlet 6004 and disc sleeve outlet 6005; The side of seed plate 602 is inwardly provided with a groove along the circumference; The groove is uniformly provided with several pawls 6021; One end of pawl 6021 is rotatably connected with the upper and lower end surfaces of the groove of seed plate 602; Each pawl 6021 is correspondingly provided with a brake spring piece 6022; One end of brake spring piece 6022 is fixedly connected with the inner end surface of seed plate 602, and the other end is pressed against the inner end surface of corresponding pawl 6021; The inner side of disc sleeve 600 is provided with a tooth groove 6003 matched with pawl 6021, that is, the inner side of side disc body 6002 is provided with tooth groove 6003; The interval distance between disc sleeve inlet 6004 and disc sleeve outlet 6005 in the horizontal direction matches the interval distance between two adjacent seed slots 6020 on seed plate 602;

[0033] In the embodiment, by setting pawl 6021 and tooth groove 6003 on the inner side of side disc body 6002 of disc sleeve 600, seed plate 602 can be driven by transmission assembly 61 to rotate unidirectionally in disc sleeve 600 in a predetermined direction; And by correspondingly setting brake spring piece 6022 beside each pawl 6021, when seed plate 602 needs to stop rotating, the inertia effect of seed plate 602 is weakened under the interaction of tooth groove 6003 and brake spring piece 6022, so that seed plate 602 can stop rotating immediately, and the uniformity of seed is improved;

[0034] In the embodiment, when seed plate 602 stops rotating, a certain seed slot 6020 on seed plate 602 is communicated with second connecting pipe 5 through disc sleeve inlet 6004, and then connected with unequal distance spiral separation transmission mechanism, so that seeds can fall into seed slot 6020; The required number of seeds falling into each seed slot 6020 can be set according to the type of seeds, for example, 8-10 buckwheat, 3-5 soybeans and corn; The interval between adjacent seed slots 6020 is determined by the interval between adjacent seed holes; The size of seed slot 6020 is determined by the size of the required seeds and the number of seeds required to be sown in each seed hole;

[0035] By matching the interval distance between disc sleeve inlet 6004 and disc sleeve outlet 6005 in the horizontal direction with the interval distance between two adjacent seed slots 6020 on seed plate 602, the seeds in the seed slot 6020 that has completed filling can fall into the seed hole as soon as possible with the operation of the equipment, complete sowing, avoid the seeds staying in the seed slot 6020 for too long, and the seeds and disc sleeve 600 rubbing with the operation of seed plate 602, causing seed wear.

[0036] Further, referring to Figure 6 and 7 , in order to achieve the seed in the seed plate 602 in the slot and the uniformity of the seeding, the transmission assembly 61, disposed below the seed plate 602, comprises: a first bevel gear 610, a second bevel gear 611, a first transmission shaft 612, a center shaft 613, an incomplete gear 614 and a complete gear 615; the first bevel gear 610 is fixedly sleeved on the front axle 11 of the vehicle body 1; the second bevel gear 611 is fixedly sleeved on one end of the first transmission shaft 612 and engaged with the first bevel gear 610; the incomplete gear 614 is fixedly sleeved on the other end of the first transmission shaft 612; the first transmission shaft 612 is at a 90-degree angle with the front axle 11 of the vehicle body 1; the top end of the center shaft 613 penetrates the bottom center of the disc sleeve 600, i.e. the lower disc cover 6001, and is fixedly connected with the bottom center of the seed plate 602 through a second flange type bearing 616; the bottom end of the center shaft 613 is fixedly connected with the complete gear 615; the incomplete gear 614 and the complete gear 615 are both arranged parallel below the seed plate 602; the complete gear 615 is engaged with the incomplete gear 614.

[0037] In the present embodiment, through the above arrangement, a first bevel gear 610-second bevel gear 611-first transmission shaft 612-incomplete gear 614 transmission path is formed, so that the incomplete gear 614 can be rotated under the drive of the front axle 11; and further, an incomplete gear 614-complete gear 615-center shaft 613-seed plate 602 transmission path is formed, so that the seed plate 602 can be rotated in one direction in the disc sleeve 600 under the drive of the front axle 11; at the same time, through the arrangement of the incomplete gear 614 and the complete gear 615, when the tooth surface of the incomplete gear 614 is engaged with the complete gear 615, the seed plate 602 rotates, and when the toothless surface of the incomplete gear 614 is opposite to the complete gear 615, the seed plate 602 is stationary; when the seed plate 602 is stationary, a certain seed groove 6020 thereon is in communication with the second connecting pipe 5, so that seeds can fall into the seed groove 6020 in a predetermined amount, completing the "seeding" of the seed groove 6020; when the seed plate 602 rotates, the seeds that have been gathered in the last seed groove 6020 are pushed by the seed plate 602, and when the seed groove 6020 coincides with the disc sleeve outlet 6005, the seeds fall into the seed hole through the seed guide pipe 601, completing the seeding; the size of the tooth surface and the toothless surface on the incomplete gear 614 is determined by the interval between adjacent seed holes and the number of seeds required for each seed hole.

[0038] Further, referring to Figure 3 and 6In order to realize the seed gathering in the seed plate 602 and ensure the uniform seeding, the control assembly includes an infrared counting sensor 620, a laser displacement sensor 621 and a receiving controller (not shown in the figure); the infrared counting sensor 620 and the laser displacement sensor 621 are in communication connection with the receiving controller (not shown in the figure); wherein the infrared counting sensor 620 is fixedly arranged on the inner wall of the second connecting pipe 5, used for counting the seeds falling into the seed plate assembly 60 from the unequal distance spiral separation and transmission assembly 41, and sending a stop signal to the receiving controller (not shown in the figure) when a counting cycle is completed; the laser displacement sensor 621 is fixedly arranged near the intersection of the incomplete gear 614 and the complete gear 615; when the laser displacement sensor 621 detects that the incomplete gear 614 and the complete gear 615 stop engaging, a start signal is sent to the receiving controller (not shown in the figure); when the laser displacement sensor 621 detects that the incomplete gear 614 and the complete gear 615 start engaging, a stop signal is sent to the receiving controller (not shown in the figure); the receiving controller (not shown in the figure) is in communication connection with the start switch of the transmission motor 40, and controls the start and stop of the transmission motor 40 according to the received start or stop signal, thereby controlling the operation of the unequal distance spiral separation and transmission assembly 41.

[0039] In the embodiment, the detection lens of the laser displacement sensor 621 is directly opposite the intersection of the incomplete gear 614 and the complete gear 615; when the tooth surface of the incomplete gear 614 engages with the tooth surface of the complete gear 615, and the toothless surface of the incomplete gear 614 is opposite to the tooth surface of the complete gear 615, the information of the scattered laser beams received by the detection lens is different, so that whether the tooth surface of the complete gear 615 engages with the tooth surface of the incomplete gear 614 can be detected; therefore, when the incomplete gear 614 and the complete gear 615 start engaging, the laser displacement sensor 621 can send a “stop” signal to the receiving controller (not shown in the figure) according to the signal; when the incomplete gear 614 and the complete gear 615 stop engaging, the laser displacement sensor 621 can send a “start” signal to the receiving controller (not shown in the figure) according to the signal;

[0040] The “start” signal and the “stop” signal are used to control the start and stop of the transmission motor 40, and also match the rotation of the seed plate 602 in the disc sleeve 600;

[0041] According to the structure of the transmission assembly 61, when the incomplete gear 614 starts to mesh with the complete gear, the seed plate 602 starts to rotate, the disc sleeve inlet 6004 starts to transfer from coinciding with one seed groove 6020 to another adjacent seed groove 6020, that is, the seed groove 6020 is in transition, and the seed groove 6020 cannot receive the seeds from the non-equidistant spiral separation transmission assembly 41 at this time, so the receiving controller (not shown in the figure) controls the transmission motor 40 to stop working according to the received “stop” signal, and the seeds in the non-equidistant spiral separation transmission assembly 41 also stop being delivered to the seed groove 6020; when the incomplete gear 614 stops meshing with the complete gear 615, the seed plate 602 stops rotating, the transition of the seed groove 6020 is completed, and a new seed groove 6020 is in communication with the second connecting pipe 5 through the disc sleeve inlet 6004, so the receiving controller (not shown in the figure) controls the transmission motor 40 to start working according to the received “start” signal, and the seeds in the non-equidistant spiral separation transmission assembly 41 also start to be delivered to the new seed groove 6020;

[0042] At the same time, the infrared counting sensor 620 is arranged to count the seeds falling into the seed groove 6020 from the non-equidistant spiral separation transmission assembly 41, and when the falling seeds reach the initial value of the set range, the infrared counting sensor 620 sends a “stop” signal to the receiving controller (not shown in the figure), and the receiving controller (not shown in the figure) controls the transmission motor 40 to stop working according to the received “stop” signal, at this time, the number of seeds required to be gathered in this seed groove 6020 has reached the set requirement, and the seed delivery is temporarily stopped.

[0043] Therefore, with the rotation of the wheel 12, the incomplete gear 614 and the complete gear 615 are driven to rotate, thereby driving the transition of the seed groove 6020, and through the start-stop cooperation of the control assembly on the transmission motor 40, the gathering of the seeds in different seed grooves 6020 and the sowing of the seeds from the seed guide pipe 601 to the seed holes are realized, and the above process forms a cycle, realizing the smooth transmission, gathering and uniform sowing of the seeds.

[0044] Further, in order to ensure that the seeds can accurately fall into the seed groove 6020, the transition time between adjacent seed grooves 6020 during the rotation of the seed plate 602 is matched with the transition time between the initial meshing and the terminal meshing of the incomplete gear 614 and the complete gear 615.

[0045] Further, referring to Figure 1 , the seed storage mechanism comprises a seed storage bin 20 arranged on the top of the vehicle body 1, four legs of the seed storage bin 20 are connected with the vehicle body 1 through springs 21, an outlet is formed in the bottom of the seed storage bin 20, the outlet is in communication with the inlet of the non-equidistant spiral separation transmission assembly 41 through a first flexible connecting pipe 3, and a vibration motor 22 is fixedly arranged on the outer side of the seed storage bin 20.

[0046] In the embodiment, by arranging the vibration motor 22 on the outer side of the seed storage bin 20, when the seeds are sent from the seed storage bin 20 to the non-equidistant spiral separation transmission mechanism, the vibration of the vibration motor 22 can make the stacked seeds fall into the non-equidistant spiral separation transmission mechanism more smoothly through the first soft connecting pipe 3; the vibration motor 22 is provided with a switch, and the vibration motor 22 can be selectively used according to the falling condition of the seeds; and the springs 21 are arranged at four corners of the seed storage bin 20, and cooperate with the first soft connecting pipe 3, so that the seed storage bin 20 can be smoothly vibrated when being driven to vibrate by the vibration motor 22, and the influence of the seed storage bin 20 on other connecting mechanisms on the vehicle body 1 during vibration is reduced.

[0047] Further, referring to Figure 1 and 2 , in order to make the seeds accurately fall into the seed holes and smoothly germinate, the reclamation mechanism comprises: a furrow opener 70 fixedly arranged on the middle line of the bottom of the front end of the vehicle body 1; and a coverer 71 fixedly arranged on the middle line of the bottom of the rear end of the vehicle body 1; the positions of the furrow opener 70 and the coverer 71 are matched with the outlet position of the seed sowing mechanism.

[0048] In the embodiment, by arranging the positions of the furrow opener 70 and the coverer 71, on the one hand, the seeds can accurately fall into the seed holes, and on the other hand, the seeds falling into the seed holes can be timely covered by the soil along with the operation of the hole sowing seeding machine, so that the smooth germination of the seeds is ensured.

[0049] The working principle and process of the utility model are as follows:

[0050] Taking sowing buckwheat as an example, 8-10 seeds are gathered in each seed groove 6020 according to the required number of seeds for each seed hole:

[0051] Firstly, in the initial stage, the operator places buckwheat seeds in the seed storage bin 20, and hangs the utility model on the tractor through the trailing arm 14 of the vehicle body 1, and under the traction of the tractor, the utility model starts to operate;

[0052] With the traction of the tractor, the front wheel shaft 11 is driven to rotate by the wheel 12, and then the incomplete gear 614 is driven to rotate by the first bevel gear 610, the second bevel gear 611 and the first transmission shaft 612;

[0053] When the laser displacement sensor 621 detects that the tooth surface of the incomplete gear 614 starts to mesh with the complete gear 615, a first “stop” signal is sent to the receiving controller (not shown in the figure); at this time, since the transmission motor 40 has not been started, this signal will be ignored;

[0054] With the wheel 12 rotating, when the laser displacement sensor 621 detects that the incomplete gear 614 and the complete gear 615 stop engaging, a "start" signal is sent to the receiving controller (not shown in the figure), which controls the transmission motor 40 to start and drive the unequal pitch spiral 412 to start running, and the seeds falling into the unequal pitch spiral transmission assembly from the seed storage bin 20 are transmitted; with the transmission of the seeds in the unequal pitch spiral transmission assembly 41, the seeds change from a dense distribution at the entrance to a single seed separation state when reaching the exit, and the unequal pitch spiral transmission assembly 41 is also filled with seeds in a dense to sparse state along the transmission direction;

[0055] With the wheel 12 continuing to rotate, when the laser displacement sensor 621 detects that the incomplete gear 614 and the complete gear 615 start engaging, a "stop" signal is sent to the receiving controller (not shown in the figure), and the transmission motor 40 stops running; at the same time, the central shaft 613 is driven by the complete gear 615 to drive the seed plate 602 to rotate in the sleeve 600 in a predetermined direction, and during the process of the incomplete gear 614 and the complete gear 615 from starting to engaging to stopping engaging, the sleeve entrance 6004 also rotates from being opposite to one seed groove 6020 to being opposite to another adjacent seed groove 6020, and the seed plate 602 completes the conversion of the seed groove 6020;

[0056] With the wheel 12 continuing to rotate, when the laser displacement sensor 621 detects that the incomplete gear 614 and the complete gear 615 stop engaging, a "start" signal is sent to the receiving controller (not shown in the figure), and the transmission motor 40 stops running; at the same time, the central shaft 613 is driven by the complete gear 615 to drive the seed plate 602 to rotate in the sleeve 600 in a predetermined direction, and during the process of the incomplete gear 614 and the complete gear 615 from starting to engaging to stopping engaging, the sleeve entrance 6004 also rotates from being opposite to one seed groove 6020 to being opposite to another adjacent seed groove 6020, and the seed plate 602 completes the conversion of the seed groove 6020;

[0057] Then, when the laser displacement sensor 621 detects that the incomplete gear 614 and the complete gear 615 start engaging again, the stopped transmission motor 40 receives a "stop" signal again, and the current seed groove 6020 starts to convert to the next seed groove 6020, and during the conversion process, the last seed groove 6020 that has completed the seed filling, with the rotation of the seed plate 602, rotates to a position opposite to the seed guide pipe 601, and under the pushing force of the seed plate 602, the seeds fall into the seed hole along with the seed guide pipe 601, completing a "seeding" of a seed hole,

[0058] Next, as the wheel 12 runs, the above-mentioned "filling" - "sowing" process is repeated in cooperation with the furrower 70 arranged at the front of the vehicle body 1 and the coverer 71 arranged at the rear of the vehicle body 1.

[0059] The seed drill has the advantages that: on the one hand, the unequal-distance spiral separation transmission mechanism is arranged, so that the seeds are separated and transmitted from the seed storage mechanism to the seed distribution mechanism, and the problem of blockage of the seeds in the transmission process due to dense distribution is solved; on the other hand, the seed distribution mechanism is arranged, so that when the separated seeds are received, the seeds are gathered in slots according to the number of seeds required by each seed hole according to planting requirements, and the seeds are sown in the corresponding seed holes in cooperation with the reclamation mechanism, the uniform sowing of the seeds is realized, compared with the prior art, the transmission of the seeds is smoother, the sowing is more uniform, the planting efficiency is improved, the resource waste is reduced, the spread and diffusion of diseases and pests are reduced through the improvement of the uniformity of crops, and finally the yield and quality of crops are improved.

[0060] The above only discloses the preferred embodiments of the utility model, of course, cannot with this to limit the utility model right scope, the person skilled in the art can understand that the whole or part processes of the above-mentioned embodiments are realized, and equivalent changes made according to the utility model claim still belong to the range covered by the utility model.
