Description

Technical Field

[0001] The invention relates to the field of seed sowing, and in particular to a melon seed sowing device. Background Art

[0002] Melon is a popular fruit and its seeds require several aspects to be paid attention to when sowing to ensure good germination rate and healthy seedling growth.

[0003] When sowing melon seeds, spread the seeds evenly in the pre-opened furrows or sow them in small holes at a certain interval. Place 2-3 seeds in each hole, then lightly cover with a thin layer of soil (about 1-2 cm thick). It should not be too thick so as not to affect the germination speed.

[0004] In the process of automated sowing of melon seeds, since melon seeds are small and flat, errors occur in the delivery of melon seeds, resulting in too many or too few seeds being delivered to a sowing position, which affects the germination rate when the sowing amount is too small, and causes crowded plants and waste of seeds when the sowing amount is too large. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a melon seed sowing device.

[0006] In a first aspect, the present invention provides a melon seed sowing device, comprising a box body, a movable base is installed at the bottom of the box body, and further comprising:

[0007] A storage box, fixedly installed inside the box body;

[0008] A discharge cylinder is fixed inside the box body, and the seeds stored inside the storage box flow into the discharge cylinder through the discharge port;

[0009] A drop hopper is fixed to the bottom of the box and is connected to the box;

[0010] A metering assembly is installed inside the box body, and is used to accurately measure the seeds inside the discharge barrel and convey the measured seeds to the drop hopper;

[0011] A sowing pipe, fixedly connected to the bottom of the drop hopper;

[0012] A coulter is fixed to the outer wall of the sowing tube, and the bottom of the coulter is hollow and connected to the sowing tube;

[0013] During sowing, the operator pushes the mobile base to drive the box to the land where sowing is required. At this time, the land has been turned over, and the storage box stores melon seeds to be sown. At this time, the box drives the plowshare to move, and the plowshare is immersed in the soil, so that the plowshare pushes the soil to both sides to form a sowing groove for sowing melon seeds. The seeds stored in the storage box pass through the discharge port and enter the inside of the discharge barrel. Then, under the action of the metering component, 2-3 seeds are transferred quantitatively to the inside of the hopper, and then the melon seeds slide from the hopper to the discharge barrel, along the discharge barrel into the hollow part of the plowshare, and then fall into the sowing groove. The sowing spacing of the melon seeds is adjusted by controlling the speed of the metering component to transfer the melon seeds and the moving speed of the mobile base, which is beneficial to quantitatively sow the melon seeds in each sowing pit, and to control the sowing amount of melon seeds, thereby helping to avoid affecting the germination efficiency and causing seed waste.

[0014] Preferably, the metering component comprises:

[0015] A mobile frame is installed inside the box body through a mobile driving assembly, and the mobile driving assembly is used to drive the mobile frame to move between the discharge cylinder and the top of the drop hopper;

[0016] A first negative pressure box is fixed on the side wall of the mobile frame;

[0017] A plurality of first negative pressure tubes are arranged in an array at the bottom of the first negative pressure box;

[0018] A plurality of micro pumps are fixed on the side wall of the mobile frame, and one of the micro pumps corresponds to one of the first negative pressure tubes, and an input end of the micro pump is connected to the corresponding first negative pressure tube;

[0019] The mobile driving component drives the mobile frame to move between the discharge barrel and the top of the drop hopper. After the mobile frame moves to the top of the discharge barrel, it moves downward until it moves to the melon seeds inside the discharge barrel, and then the micro pump is started. After the micro pump is started, the air inside the first negative pressure tube is extracted, so that a negative pressure space is formed inside the first negative pressure tube. At this time, the first negative pressure box is against the top of the melon seeds. The melon seeds are adsorbed at the bottom opening of the first negative pressure tube through the negative pressure effect. The bottom opening of the first negative pressure tube is set to flexible rubber, so as to fit the surface curvature of the melon seeds, which is conducive to the melon seeds being adsorbed and transferred. After all the melon seeds are adsorbed, the mobile driving component is controlled to drive the mobile frame to move to the top of the drop hopper, and then the corresponding micro pump is controlled to be closed, so that the adsorbed melon seeds lose the negative pressure effect and fall into the drop hopper to complete the transfer process of the melon seeds. Through the adsorption of one melon seed corresponding to one first negative pressure tube, the transfer amount of the melon seeds is quantitative, which is conducive to avoiding the situation of too little or too much melon seeds when sowing.

[0020] Preferably, the metering component further comprises:

[0021] A plurality of pressure sensors are respectively fixed inside each of the first negative pressure tubes;

[0022] The pressure sensor can detect the air pressure inside the first negative pressure tube. When the melon seeds are not adsorbed on the bottom of the first negative pressure tube, the bottom of the first negative pressure tube is blocked and the airflow cannot flow. At this time, the negative pressure inside the first negative pressure tube rises, so that when the pressure sensor detects that the negative pressure inside the first negative pressure tube reaches a specified amount, the first negative pressure tube completes the adsorption of the melon seeds. When the pressure sensor detects that the air pressure inside the first negative pressure tube does not change, the bottom of the first negative pressure tube is in an airflow circulation state, and the adsorption of the melon seeds is not completed. Therefore, through the setting of the pressure sensor, the adsorption of the melon seeds can be detected, which is conducive to detecting the transfer amount of the melon seeds, thereby facilitating the improvement of the accuracy of melon seed sowing.

[0023] There are multiple first negative pressure tubes, so that the moving frame can transfer multiple seeds each time it performs a transfer. After the moving frame moves to just above the drop hopper, 2-3 micro pumps are controlled to be closed each time, so that 2-3 melon seeds are controlled to fall each time. The pressure sensor can identify the first negative pressure tube that has not absorbed melon seeds. Therefore, when the micro pump is controlled to be closed to drop the melon seeds, the micro pump corresponding to the first negative pressure tube that has not absorbed melon seeds is not counted, so that the first negative pressure tube that has not absorbed melon seeds is skipped, which is beneficial to improve the accuracy of melon seed sowing.

[0024] Preferably, it also includes:

[0025] A fixed box, fixed to the top of the drop hopper;

[0026] A plurality of storage cavities are provided in a circular array through the top of the fixed box;

[0027] A first conveying bucket and a second conveying bucket are rotatably mounted on the bottom and top of the fixed box through a second drive group and a first drive group, respectively, a top inlet of the first conveying bucket is aligned with one of the storage chambers, a bottom of the first conveying bucket is aligned and communicated with the drop bucket, and a bottom outlet of the second conveying bucket is aligned with one of the storage chambers;

[0028] The second driving group and the first driving group both include a driving motor and a driving gear, so that the driving motor drives the driving gear to rotate, and the driving gear drives the first conveying bucket and the second conveying bucket to rotate, thereby realizing the driving of the first conveying bucket and the second conveying bucket;

[0029] The second conveying hopper is located just above the dropping hopper. When the metering component transfers the melon seeds to just above the dropping hopper, the melon seeds first fall into the second conveying hopper, and then enter into one of the storage cavities along the second conveying hopper. By driving the second conveying hopper, the metering component drives the second conveying hopper to rotate the distance of a storage cavity each time 2-3 seeds are released, so that the inside of each storage cavity is filled with seeds in turn, so that a certain amount of seeds is maintained inside the storage cavity, which is conducive to avoiding the situation that no melon seeds fall into the dropping hopper when the metering component takes extra time to transfer the melon seeds, resulting in a situation where the sowing spacing of the melon seeds is too large, thereby helping to improve the uniformity of melon seed sowing;

[0030] During the rotation of the first conveying bucket, the top of the first conveying bucket is aligned with each storage cavity in turn, so that the melon seeds inside the storage cavity fall into the first conveying bucket in turn and then fall into the drop bucket for sowing, which is beneficial to the continuous sowing of melon seeds and helps to improve the uniformity of melon seed sowing.

[0031] Preferably, it also includes:

[0032] A mounting box, fixed to the inner wall of the storage box;

[0033] A first cylinder, fixed inside the installation box;

[0034] A partition is vertically slidably mounted on the edge of the discharge port to block the discharge port, the end of the telescopic rod of the first cylinder is fixedly connected to the top of the partition, and the bottom of the partition passes through the storage box and the bottom of the box body;

[0035] After the first cylinder is started, the telescopic rod drives the partition connected to it to move vertically. When the partition moves downward, the discharge port is exposed, so that the melon seeds inside the storage box can pass through the discharge port and enter the inside of the discharge barrel. When the partition moves upward to block the discharge port, the discharge barrel can be blocked, so that the melon seeds are temporarily unable to enter the inside of the discharge barrel, which helps to avoid excessive overflow of melon seeds inside the discharge barrel.

[0036] Preferably, it also includes:

[0037] A soil storage box is fixedly installed inside the box body, and the top of the soil storage box is a ventilation plate;

[0038] A second guide plate is fixed inside the soil storage box;

[0039] A soil covering pipe, fixedly connected to the bottom of the soil storage box, with the top connected to the bottom of the second guide plate, the bottom connected to the hollow of the coulter and located behind the sowing pipe;

[0040] A collecting assembly is installed between the plow and the interior of the soil storage box, and is used to transport the crushed soil scooped up by the plow to the interior of the soil storage box;

[0041] The collecting component transports the soil dislodged by the plowshare to the interior of the soil storage box, and then the soil slides downward from the second guide plate inside the soil storage box through the soil covering pipe and enters the hollow part of the plowshare. The soil covering pipe is located behind the sowing pipe. The rear here refers to the rear of the moving direction of the box body, that is, the position where the soil covering pipe passes through the sowing pipe, so that the soil covering pipe can cover the soil at the position after the sowing pipe is sown, thereby covering the melon seeds with soil, which helps to avoid the situation where the sown melon seeds are exposed to the outside and affect the germination efficiency.

[0042] Preferably, the collecting assembly comprises:

[0043] Two second negative pressure pipes are symmetrically fixed to the bottom of the box body, the bottom of the second negative pressure pipe faces the plow blade, and the top of the second negative pressure pipe passes through the box body and the bottom of the soil storage box and extends to the inside of the soil storage box;

[0044] Two second negative pressure boxes are respectively fixed on the tops of the two second negative pressure tubes;

[0045] Two negative pressure pumps are respectively fixed on the side walls of the two second negative pressure boxes and are respectively connected to the two second negative pressure boxes;

[0046] Two blocking blocks are respectively inserted vertically and slidably into the bottom openings of the two second negative pressure boxes to block the openings, and the tops of the blocking blocks are arranged as inclined surfaces;

[0047] Two third cylinders are fixed inside the soil storage box, and drive the two blocking blocks to move vertically through the top telescopic rods respectively;

[0048] After the negative pressure pump is started, the soil pushed to both sides by the plowshare by its own strong suction force enters the second negative pressure box along the trajectory of the second negative pressure pipe, and then accumulates inside the second negative pressure box. At this time, the third cylinder is controlled to start, and the third cylinder drives the blocking block to move downward, so that the opening is exposed, so that the soil accumulated inside the second negative pressure box falls along the slope, so that the soil enters above the second guide plate, and the soil is collected and then covered with soil, which is conducive to preventing the plowshare from automatically resetting after pushing the soil away and covering the melon seeds, causing the melon seeds to be exposed.

[0049] The second negative pressure tubes on both sides are alternately arranged so that when some openings are exposed, the openings on the other side are in a blocked state, so that there are always second negative pressure tubes maintaining a negative pressure adsorption state, which is conducive to continuous collection of soil.

[0050] Preferably, it also includes:

[0051] A soil crushing box is fixed inside the soil storage box, and the top of the soil crushing box is located directly above the second guide plate;

[0052] A filter plate is provided through the bottom of the soil crushing box to screen the particle size of the soil blocks entering the second guide plate from the inside of the soil crushing box;

[0053] A second motor is fixed to the top of the soil crushing box;

[0054] A crushing knife, fixed to the output shaft of the second motor and located inside the soil crushing box;

[0055] The soil that falls from the second negative pressure box enters the filter plate inside the soil crushing box. After the second motor is started, it drives the crushing knife to rotate through the output shaft. The crushing knife crushes the collected soil after rotating. The crushed soil can pass through the filter plate and fall along the second guide plate, which is beneficial to crushing the covered soil, and is beneficial to avoiding the situation where the soil clods are too large, resulting in uneven coverage of the melon seeds, causing partial exposure of the melon seeds, and avoiding the situation where the melon seeds are exposed and affect the germination rate.

[0056] Preferably, the mobile drive assembly comprises:

[0057] A screw rod is rotatably mounted on the side wall of the storage box through a bracket;

[0058] A first motor is fixed on the side wall of the storage box, and the first motor drives the screw rod to rotate through an output shaft;

[0059] A moving box, which is threadedly sleeved on the outer ring of the screw rod and is slidably connected to the side wall of the storage box;

[0060] A second cylinder is fixed inside the moving box, and the second cylinder drives the moving frame to move vertically through a telescopic rod;

[0061] After the first motor is started, it drives the screw to rotate through the output shaft. After the screw rotates, it drives the moving box threadedly connected to it to move. The moving box drives the second cylinder and the moving frame to move horizontally, thereby realizing the horizontal drive of the moving frame. After the second cylinder is started, it can drive the moving frame to move vertically through the telescopic rod, thereby realizing the vertical drive of the moving frame, thereby realizing the reciprocating drive of the moving frame between the discharge barrel and the top of the drop hopper.

[0062] Preferably, it also includes:

[0063] A first guide plate fixed inside the storage box;

[0064] The first guide plate can guide the melon seeds inside the storage box so that the seeds inside the storage box can slide toward the discharge barrel, which is beneficial for the melon seeds to converge toward the discharge barrel, thereby achieving the filling of the melon seeds into the discharge barrel.

[0065] Compared with the prior art, the present invention has the following beneficial effects:

[0066] The present invention is advantageous for quantitatively sowing the melon seeds in each sowing pit through the arrangement of the metering component, and is advantageous for controlling the sowing amount of the melon seeds, thereby facilitating avoiding the situation of affecting the germination efficiency and causing seed waste.

DETAILED DESCRIPTION

[0078] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0079] like Figures 2 to 10 The melon seed sowing device shown comprises a box body 1, a movable base 101 is installed at the bottom of the box body 1, and further comprises:

[0080] The storage box 2 is fixedly installed inside the box body 1;

[0081] The discharge cylinder 3 is fixed inside the box body 1, and the seeds stored inside the storage box 2 flow into the discharge cylinder 3 through the discharge port 202;

[0082] The hopper 602 is fixed to the bottom of the box body 1 and is connected to the box body 1;

[0083] The metering assembly is installed inside the box body 1 and is used to accurately measure the seeds inside the discharge cylinder 3 and transport the measured seeds to the drop hopper 602;

[0084] The sowing pipe 6 is fixedly connected to the bottom of the drop hopper 602;

[0085] The coulter 601 is fixed to the outer wall of the sowing tube 6, and the bottom of the coulter 601 is hollow and connected to the sowing tube 6;

[0086] When sowing melon seeds, spread the seeds evenly in the pre-opened furrows or sow them in small holes at a certain interval, placing 2-3 seeds in each hole, and then lightly cover with a thin layer of soil about 1-2 cm thick. It should not be too thick to avoid affecting the germination speed.

[0087] In the process of automatic sowing of melon seeds, since melon seeds are small and flat, there are errors in the delivery process of melon seeds, which causes too many or too few seeds to be delivered to a sowing position, thus affecting the germination rate when the sowing amount is too small, and causing crowded plants and waste of seeds when the sowing amount is too large.

[0088] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. During sowing, the operator pushes the mobile base 101 to drive the box body 1 to the land where sowing is required. At this time, the land has been turned over, and the storage box 2 stores melon seeds that need to be sown. At this time, the box body 1 drives the plow 601 to move, and the plow 601 is immersed in the soil, so that the plow 601 pushes the soil to move to both sides to form a sowing ditch for sowing melon seeds. The seeds stored in the storage box 2 pass through the discharge port 202 and enter the inside of the discharge barrel 3, and then under the action of the metering component , 2-3 seeds are quantitatively transferred to the inside of the drop hopper 602, and then the melon seeds slide from the drop hopper 602 to the discharge cylinder 3, enter the hollow inside the plow 601 along the discharge cylinder 3, and then fall into the inside of the sowing furrow. The sowing spacing of the melon seeds is adjusted by controlling the speed of the metering component to transfer the melon seeds and the moving speed of the mobile base 101, which is beneficial for quantitative sowing of the melon seeds in each sowing pit, and is beneficial for controlling the sowing amount of melon seeds, thereby helping to avoid affecting the germination efficiency and causing seed waste.

[0089] As an optional embodiment, the metering component includes:

[0090] The mobile frame 4 is installed inside the box body 1 through a mobile driving assembly, and the mobile driving assembly is used to drive the mobile frame 4 to move between the discharge cylinder 3 and the top of the drop hopper 602;

[0091] The first negative pressure box 5 is fixed on the side wall of the mobile frame 4;

[0092] A plurality of first negative pressure tubes 501 are arranged in an array at the bottom of the first negative pressure box 5;

[0093] A plurality of micro pumps 502 are fixed on the side wall of the mobile frame 4, and one micro pump 502 corresponds to one first negative pressure tube 501, and the input end of the micro pump 502 is connected to the corresponding first negative pressure tube 501;

[0094] The mobile driving assembly drives the mobile frame 4 to move between the discharge barrel 3 and the top of the drop hopper 602. After the mobile frame 4 moves to the top of the discharge barrel 3, it moves downward until it moves to the melon seeds inside the discharge barrel 3, and then the micro pump 502 is started. After the micro pump 502 is started, the air inside the first negative pressure tube 501 is extracted, so that a negative pressure space is formed inside the first negative pressure tube 501. At this time, the first negative pressure box 5 is against the top of the melon seeds. The melon seeds are adsorbed at the bottom opening of the first negative pressure tube 501 through the negative pressure effect. The bottom opening of the first negative pressure tube 501 is set to be flexible. The rubber can fit the surface curvature of the melon seeds, which is beneficial for the melon seeds to be fitted and adsorbed for transfer. After all the melon seeds are adsorbed, the mobile drive component is controlled to drive the mobile frame 4 to move to the top of the drop hopper 602, and then the corresponding micro pump 502 is controlled to be closed, so that the adsorbed melon seeds lose the negative pressure effect and fall into the drop hopper 602 to complete the transfer process of the melon seeds. Through a first negative pressure tube 501 corresponding to the adsorption of a melon seed, the transfer amount of the melon seeds is quantitative, which is beneficial to avoid the situation where too little or too much melon seeds are sown.

[0095] As an optional embodiment, the metering component further includes:

[0096] A plurality of pressure sensors 503 are respectively fixed inside each first negative pressure tube 501;

[0097] The pressure sensor 503 can detect the air pressure inside the first negative pressure tube 501. When the melon seeds are not adsorbed on the bottom of the first negative pressure tube 501, the bottom of the first negative pressure tube 501 is blocked and the airflow cannot flow. At this time, the negative pressure inside the first negative pressure tube 501 rises, so that when the pressure sensor 503 detects that the negative pressure inside the first negative pressure tube 501 reaches a specified amount, the first negative pressure tube 501 completes the adsorption of the melon seeds. When the pressure sensor 503 detects that the air pressure inside the first negative pressure tube 501 does not change, the bottom of the first negative pressure tube 501 is in a state of airflow circulation, and the adsorption of the melon seeds is not completed. Therefore, through the setting of the pressure sensor 503, the adsorption of the melon seeds can be detected, which is conducive to detecting the transfer amount of the melon seeds, thereby facilitating the improvement of the accuracy of melon seed sowing.

[0098] There are multiple first negative pressure tubes 501, so that the moving frame 4 can transfer multiple seeds each time it performs a transfer. After the moving frame 4 moves to just above the drop hopper 602, 2-3 micro pumps 502 are controlled to be closed each time, so that 2-3 melon seeds are controlled to fall each time. The pressure sensor 503 can identify the first negative pressure tube 501 that does not absorb melon seeds. Therefore, when the micro pump 502 is controlled to be closed to drop the melon seeds, the micro pump 502 corresponding to the first negative pressure tube 501 that does not absorb melon seeds is not counted, so that the first negative pressure tube 501 that does not absorb melon seeds is skipped, which is beneficial to improve the accuracy of melon seed sowing.

[0099] As an optional embodiment, it also includes:

[0100] A fixed box 605 is fixed to the top of the drop hopper 602;

[0101] A plurality of storage chambers 606 are provided in a circular array through the top of the fixed box 605;

[0102] The first conveying bucket 603 and the second conveying bucket 604 are rotatably mounted on the bottom and the top of the fixed box 605 through the second driving group 608 and the first driving group 607, respectively. The top inlet of the first conveying bucket 603 is aligned with one of the storage chambers 606, the bottom of the first conveying bucket 603 is aligned and communicated with the drop bucket 602, and the bottom outlet of the second conveying bucket 604 is aligned with one of the storage chambers 606;

[0103] The second driving group 608 and the first driving group 607 both include a driving motor and a driving gear, so that the driving motor drives the driving gear to rotate, and the driving gear drives the first conveying bucket 603 and the second conveying bucket 604 to rotate, thereby realizing the driving of the first conveying bucket 603 and the second conveying bucket 604;

[0104] The second conveying hopper 604 is located just above the dropping hopper 602. When the metering component transfers the melon seeds to just above the dropping hopper 602, the melon seeds first fall into the second conveying hopper 604, and then enter into one of the storage cavities 606 along the second conveying hopper 604. By driving the second conveying hopper 604, the metering component drives the second conveying hopper 604 to rotate the distance of the space of a storage cavity 606 each time 2-3 seeds are released, so that the inside of each storage cavity 606 is filled with seeds in turn, so that a certain amount of seeds is maintained in the storage cavity 606, which is conducive to avoiding the situation that no melon seeds fall from the dropping hopper 602 when the metering component spends extra time transferring the melon seeds, resulting in a situation where the sowing spacing of the melon seeds is too large, thereby helping to improve the uniformity of melon seed sowing;

[0105] During the rotation of the first conveying bucket 603, the top of the first conveying bucket 603 is aligned with each storage cavity 606 in turn, so that the melon seeds inside the storage cavity 606 fall into the first conveying bucket 603 in turn and then fall into the drop hopper 602 for sowing, which is beneficial to the continuous sowing of melon seeds and the improvement of the uniformity of sowing of melon seeds.

[0106] As an optional embodiment, it also includes:

[0107] The installation box 301 is fixed on the inner wall of the storage box 2;

[0108] The first cylinder 302 is fixed inside the installation box 301;

[0109] The partition 303 is vertically slidably mounted on the edge of the discharge port 202 to block the discharge port 202. The end of the telescopic rod of the first cylinder 302 is fixedly connected to the top of the partition 303. The bottom of the partition 303 passes through the bottom of the storage box 2 and the box body 1.

[0110] After the first cylinder 302 is started, the partition 303 connected thereto is driven to move vertically through the telescopic rod. When the partition 303 moves downward, the discharge port 202 is exposed, so that the melon seeds inside the storage box 2 can pass through the discharge port 202 and enter the inside of the discharge barrel 3. When the partition 303 moves upward to block the discharge port 202, the discharge barrel 3 can be blocked, so that the melon seeds are temporarily suspended from entering the inside of the discharge barrel 3, which helps to avoid excessive overflow of the melon seeds inside the discharge barrel 3.

[0111] As an optional embodiment, it also includes:

[0112] The soil storage box 701 is fixedly installed inside the box body 1, and the top of the soil storage box 701 is a ventilation plate;

[0113] The second guide plate 702 is fixed inside the soil storage box 701;

[0114] The soil covering pipe 7 is fixedly connected to the bottom of the soil storage box 701, and the top is connected to the bottom of the second guide plate 702, and the bottom is connected to the hollow of the coulter 601 and is located behind the sowing pipe 6;

[0115] A collecting assembly is installed between the plow 601 and the inside of the soil storage box 701, and is used to transport the crushed soil scooped up by the plow 601 to the inside of the soil storage box 701;

[0116] The collecting component transports the soil pushed away by the plow 601 to the interior of the soil storage box 701, and then the soil slides downward from the second guide plate 702 inside the soil storage box 701 through the covering tube 7 and enters the hollow part of the plow 601. The covering tube 7 is located behind the sowing tube 6. The rear here refers to the rear of the moving direction of the box body 1, that is, the position where the covering tube 7 moves through the sowing tube 6, so that the covering tube 7 can cover the soil at the position after the sowing tube 6 is sown, thereby covering the melon seeds with soil, which is beneficial to avoid the situation where the sown melon seeds are exposed to the outside and affect the germination efficiency.

[0117] As an optional embodiment, the collection component includes:

[0118] Two second negative pressure pipes 8 are symmetrically fixed to the bottom of the box body 1, the bottom of the second negative pressure pipe 8 faces the plow 601, and the top of the second negative pressure pipe 8 passes through the box body 1 and the bottom of the soil storage box 701 and extends to the inside of the soil storage box 701;

[0119] Two second negative pressure boxes 801 are respectively fixed on the tops of the two second negative pressure tubes 8;

[0120] Two negative pressure pumps 802 are respectively fixed on the side walls of the two second negative pressure boxes 801 and are respectively connected to the two second negative pressure boxes 801;

[0121] Two blocking blocks 803 are respectively inserted vertically into the bottom openings of the two second negative pressure boxes 801 to block the openings, and the tops of the blocking blocks 803 are set as inclined surfaces;

[0122] Two third cylinders 804 are fixed inside the soil storage box 701, and drive the two blocking blocks 803 to move vertically through the top telescopic rods respectively;

[0123] After the negative pressure pump 802 is started, the soil pushed to both sides by the plow 601 through its own strong suction force enters the second negative pressure box 801 along the trajectory of the second negative pressure pipe 8, and then accumulates in the second negative pressure box 801. At this time, the third cylinder 804 is controlled to start, and the third cylinder 804 drives the blocking block 803 to move downward, so that the opening is exposed, so that the soil accumulated in the second negative pressure box 801 falls along the slope, so that the soil enters the top of the second guide plate 702, and the soil is collected and then covered with soil, which is conducive to preventing the plow 601 from automatically resetting after pushing the soil away and covering the melon seeds, causing the melon seeds to be exposed;

[0124] The second negative pressure tubes 8 on both sides are alternately arranged so that when some openings are exposed, the openings on the other side are in a blocked state, so that there are always second negative pressure tubes 8 maintaining a negative pressure adsorption state, which is conducive to continuous collection of soil.

[0125] As an optional embodiment, it also includes:

[0126] The soil crushing box 9 is fixed inside the soil storage box 701, and the top of the soil crushing box 9 is located directly above the second guide plate 702;

[0127] The filter plate 901 is provided through the bottom of the soil crushing box 9 to screen the granularity of the soil blocks entering the second guide plate 702 from the soil crushing box 9;

[0128] The second motor 1001 is fixed to the top of the soil crushing box 9;

[0129] The crushing blade 10 is fixed to the output shaft of the second motor 1001 and is located inside the soil crushing box 9;

[0130] The soil dropped from the second negative pressure box 801 enters the filter plate 901 inside the soil crushing box 9. After the second motor 1001 is started, the crushing knife 10 is driven to rotate through the output shaft. After the crushing knife 10 rotates, the collected soil is crushed. The crushed soil can pass through the filter plate 901 and fall along the second guide plate 702, which is beneficial to crush the covered soil and prevent the soil clods from being too large, resulting in uneven coverage of the melon seeds and partial exposure of the melon seeds. This is beneficial to prevent the melon seeds from being exposed and affecting the germination rate.

[0131] As an optional embodiment, the mobile driving component includes:

[0132] The screw rod 403 is rotatably mounted on the side wall of the storage box 2 through a bracket;

[0133] The first motor 404 is fixed on the side wall of the storage box 2, and the first motor 404 drives the screw rod 403 to rotate through the output shaft;

[0134] The moving box 401 is threadedly sleeved on the outer ring of the screw rod 403 and is slidably connected to the side wall of the storage box 2;

[0135] The second cylinder 402 is fixed inside the moving box 401, and the second cylinder 402 drives the moving frame 4 to move vertically through the telescopic rod;

[0136] After the first motor 404 is started, it drives the screw rod 403 to rotate through the output shaft. After the screw rod 403 rotates, it drives the moving box 401 threadedly connected thereto to move. The moving box 401 drives the second cylinder 402 and the moving frame 4 to move horizontally, thereby realizing the horizontal drive of the moving frame 4. After the second cylinder 402 is started, it can drive the moving frame 4 to move vertically through the telescopic rod, thereby realizing the vertical drive of the moving frame 4, thereby realizing the reciprocating drive of the moving frame 4 between the discharge barrel 3 and the top of the drop hopper 602.

[0137] As an optional embodiment, it also includes:

[0138] A first guide plate 201 is fixed inside the storage box 2;

[0139] The first guide plate 201 can guide the melon seeds inside the storage box 2 so that the seeds inside the storage box 2 can slide toward the discharge barrel 3, which is beneficial for the melon seeds to converge toward the discharge barrel 3, thereby achieving the filling of the melon seeds into the discharge barrel 3.

[0140] The working principle of the present invention is as follows: during sowing, the operator pushes the mobile base 101 to drive the box body 1 in the land to be sown. At this time, the land has been turned over, and the storage box 2 stores melon seeds to be sown. At this time, the box body 1 drives the plow 601 to move, and the plow 601 is immersed in the soil, so that the plow 601 pushes the soil to move to both sides to form a sowing groove for sowing melon seeds. The seeds stored in the storage box 2 pass through the discharge port 202 and enter the inside of the discharge cylinder 3. Then, under the action of the metering component, 2-3 seeds are quantitatively transferred to the inside of the drop hopper 602, and then the melon seeds slide from the drop hopper 602 to the discharge cylinder 3, enter the hollow inside the plow 601 along the discharge cylinder 3, and then fall into the inside of the sowing groove. The sowing spacing of the melon seeds is adjusted by controlling the speed of the metering component to transfer the melon seeds and the moving speed of the mobile base 101, so as to facilitate the quantitative sowing of the melon seeds in each sowing pit, and to control the sowing amount of the melon seeds, so as to avoid affecting the germination efficiency and causing seed waste.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
