The discharge gate blocks a part of the discharge port and leaves a part unblocked. The grain seeds flow out from the unblocked part, and the area of ​​the unblocked part is proportional to the volume of the sown grain seeds, and the volume of the sown grain seeds is proportional to the sowing amount; the sowing amount refers to the mass of the grain seeds sown in one acre of land, and the unit is jin / mu.

However, due to the possibility of overlap and blockage during grain sowing, that is, the grains are too close or piled together, this will cause the sowing amount to exceed expectations or be uneven, and flexible intermittent sowing operations cannot be achieved. In intermittent sowing, farmers hope to be able to accurately control the sowing interval and adjust it according to the needs of the crops and the planting method to achieve the best planting effect. A grain sowing amount monitoring device is proposed to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] The invention discloses a grain sowing amount monitoring device, which is installed on a grain sowing machine frame and close to a discharging port of the grain sowing machine frame, and is used to monitor the sowing amount of round grains, such as Figure 1-Figure 10 As shown, it includes a support frame 1 and an L-shaped angle steel bracket 2, the support frame 1 and the L-shaped angle steel bracket 2 are both fixedly mounted on the grain seeder frame, and a hopper 3 and a guide plate 4 are fixedly mounted on the top of the support frame 1 in sequence from top to bottom, the grains are guided to the inside of the hopper 3 through the discharge port of the grain seeder frame, and roll down to the inclined guide plate 4 through the outlet at the bottom of the hopper 3, the grains can be evenly distributed during the rolling process and maintain a certain speed and direction, thereby achieving uniform sowing; each grain has the opportunity to fall at a predetermined position, avoiding aggregation or sparseness between grains, and improving the uniformity and consistency of sowing.

[0036] A guide plate 5 is fixedly installed on the top of the L-shaped angle steel bracket 2, and eight groups of guide grooves 6 are arranged on the upper surface of the guide plate 5. The grains are accurately guided to the inside of the guide groove 6 by the guidance of the guide plate 4, thereby avoiding the deviation and scattering of the grains. The guide plate 4 is located above the guide plate 5, and the guide plate 4 is inclined toward the inside of the guide groove 6. The grains are guided to the inside of the guide groove 6 by the guide plate 4. The grains are linearly arranged and orderly rolled inside the guide groove 6, and a first guide channel 7 is formed inside the guide groove 6, which can better control the distribution and density of the grains; the grains are fully mixed and contacted with each other in the guide groove 6 through mutual rolling and friction, thereby achieving a uniform distribution effect and improving the uniformity of sowing.

[0037] Specifically, the material guide trough 6 includes a first side plate 601 and a second side plate 602, the plate surfaces of the first side plate 601 and the second side plate 602 are parallel to each other, and a first material guide channel 7 is formed between the inner surface of the first side plate 601, the inner surface of the second side plate 602 and the upper surface of the guide plate 5, and the first side plate 601, the second side plate 602 and the guide plate 5 cooperate to form a boundary, which places the grains in the first material guide channel 7, limits the movement range of the grains, and makes them roll along a predetermined path.

[0038] Furthermore, the width of the guide trough 6 is matched with the grain size of a single grain, which can prevent the grain from getting stuck or blocked during the guide process; if the width of the guide trough 6 is much larger than the grain size, the grain may have an excessive lateral deviation during the guide process, resulting in blockage. On the contrary, if the width of the guide trough 6 is much smaller than the grain size, the grain may get stuck in the guide trough 6, resulting in failure to guide the grain normally. Therefore, appropriately matching the width of the guide trough 6 with the grain size can avoid these problems and ensure that the grain rolls smoothly during the guide process.

[0039] A first guide plate 603 and a second guide plate 604 are fixedly installed on the top of the first side plate 601 and the second side plate 602 and near the input end of the first material guide channel 7, respectively. The first guide plate 603 and the second guide plate 604 form a second material guide channel 8 with an "eight"-shaped structure on the upper surface of the guide plate 5. Through the second material guide channel 8 with an "eight"-shaped structure, grains can be sorted and guided within a shorter distance, reducing the retention and blockage of grains during the material guiding process, improving the speed and efficiency of the material guiding, and forming an enlarged end and a reduced end on the second material guide channel 8. The reduced end of the second material guide channel 8 faces the input end of the first material guide channel 7. The grains pass through the guide plate 4 and through the enlarged end of the second material guide channel 8 to enter the second material guide channel 8 with an "eight"-shaped structure. Through the guide component 9 arranged in the second material guide channel 8, a large number of scattered grains are linearly arranged and guided into the first material guide channel 7.

[0040] Specifically, three guide components 9 are respectively arranged along the plate surface direction of the first guide plate 603 and the second guide plate 604. The guide component 9 includes a driving motor arranged inside the guide plate 5. The output end of the driving motor is connected to a rotating shaft 901. Flexible guide strips 902 are evenly distributed on the outer diameter surface of the rotating shaft 901. The driving motor provides power to rotate the rotating shaft 901; the rotating shaft 901 is rotated, and under the rotation action of the flexible guide strips 902, the flexible guide strips 902 and the grains are squeezed and moved. Under the action of the flexible guide strips 902, the grains are pushed one by one to form a linear arrangement and accurately guided into the first material guide channel 7; this can improve the speed and efficiency of the arrangement.

[0041] Furthermore, the material of the flexible guide bar 902 is silicone, which is soft and can adapt to grains of different shapes and sizes; it can bend and deform to meet the specific requirements of the grains; this softness enables the silicone guide bar to better contact the grains, and the silicone guide bar can provide a certain buffering effect, which can reduce the collision and extrusion of the grains during the guiding process; this helps to reduce damage and breakage of the grains and improve the survival rate of grain sowing.

[0042] The inner surface of the flexible guide bar 902 is a 1 / 4 arc structure, which is used to fit the spherical surface of a single grain, reducing the rebound force exerted by the rotating flexible guide bar 902 on the grain, thereby reducing splashing, ensuring that the grain is linearly arranged along a predetermined guide path, improving the guiding effect and maintaining a good arrangement of the grain.

[0043] The guide plate 5 is provided with eight discharging openings 10 matching the number of the guide slots 6. The discharging openings 10 are located at the output end of the first guide channel 7. A connecting block 11 is movably provided inside the discharging opening 10. The connecting block 11 is rotatably connected to the discharging opening 10 through a rotating rod 12. One side of the connecting block 11 and the internal space of the discharging opening 10 form a discharging channel 13 for discharging grains. An intermittently retractable connecting rod 14 is provided inside the connecting block 11. A stopper 15 is provided on the top of the connecting rod 14. The projected area of ​​the stopper 15 is larger than the discharging opening 10. The projection area size of the opening 10 is that when the intermittently retractable connecting rod 14 slides down, the lower surface of the block 15 covers the grain discharge opening 10. At this time, the grain is blocked on one side of the block 15, and the grain discharge channel 13 is in a closed state. When the intermittently retractable connecting rod 14 rises, the lower surface of the block 15 is separated from the covering grain discharge opening 10 until the distance between the lower surface of the block 15 and the upper surface of the grain discharge opening 10 is greater than the particle size of the grain. At this time, the grain enters the grain discharge channel 13 under the action of gravity, and the grain discharge channel 13 is in an open state.

[0044] Furthermore, a limiting shaft 16 is provided on the L-shaped angle steel bracket 2, and a swing rod 17 that can swing intermittently is provided on the limiting shaft 16. One end of the swing rod 17 is rotatably connected to the limiting shaft 16, and the other end of the swing rod 17 is fixedly connected to a support plate 18. The upper surface of the support plate 18 is provided with eight sowing grooves 19 that match the grain discharge port 10. The sowing grooves 19 are located below the connecting rod 14. With the intermittent rotation of the swing rod 17, when the swing rod 17 swings upward, the sowing grooves 19 on the support plate 18 contact and press the connecting rod 14, so that the connecting rod 14 rises upward in the connecting block 11, and the lower surface of the stopper 15 is separated from the covering grain discharge port 10 until the lower surface of the stopper 15 is in contact with the upper surface of the grain discharge port 10. The spacing between the surfaces is greater than the particle size of the grains. At this time, the grain discharge channel 13 is in an open state. Under the action of gravity, the grains enter the grain discharge channel 13 and fall into the sowing groove 19. When the swing rod 17 swings downward, the sowing groove 19 on the support plate 18 moves away from the connecting rod 14, so that the connecting rod 14 slides down due to lack of pressure, and the lower surface of the block 15 covers the grain discharge port 10. At this time, the grains are blocked on one side of the block 15, and the grain discharge channel 13 is in a closed state. At the same time, the sowing groove 19 on the support plate 18 moves downward. When the support plate 18 is tilted downward, the grains in the sowing groove 19 are sown to the ground along the guide slope at the bottom of the sowing groove 19, thereby playing a sowing role.

[0045] Specifically, an insulating sleeve 20 is provided at the bottom of the connecting rod 14, and a mounting groove is provided at the bottom of the insulating sleeve 20. A magnet block is embedded in the mounting groove of the insulating sleeve 20. An iron plate 23 is provided at the bottom of the sowing groove 19. With the intermittent rotation of the swing arm 17, when the swing arm 17 swings upward, the sowing groove 19 on the support plate 18 contacts and presses the connecting rod 14. At this time, the iron plate 23 and the magnet block are adsorbed. The adsorption effect can reduce the looseness between the connecting rod 14 and the sowing groove 19 and the vibration of the connecting rod 14 and the connecting block 11, and reduce the vibration amplitude during the sowing process; this helps to reduce the overflow and sowing of grains, and ensure the accuracy and consistency of sowing; and the adsorption effect of the magnet block and the iron plate 23 can make the position of the connecting rod 14 in the swinging process more accurately positioned, ensuring that the sowing groove 19 and the connecting rod 14 are more accurately docked; this can improve the accuracy of sowing, avoid missing grains or various phenomena, and improve the growth effect of crops.

[0046] When the swing arm 17 swings downward, the sowing groove 19 slides downward together with the connecting rod 14. At this time, the magnet block and the iron plate 23 are firmly attracted, so that the inclined cut surface 21 of the lower surface of the block 15 quickly covers the grain discharge port 10, so that the grain is blocked on one side surface of the block 15, avoiding the grain from being stuck between the baffle and the grain discharge port 10, avoiding damage to the grain, and further avoiding the grain from being stuck at the grain discharge port 10, thereby ensuring the accuracy of sowing amount monitoring.

[0047] When the swing rod 17 swings downward and the magnet block and the iron plate 23 are separated, the spring 22 arranged between the connecting block 11 and the insulating sleeve 20 makes the baffle always abut against the particle discharge port 10, so that the particle discharge channel 13 is always in a closed state.

[0048] An integrated box 24 is fixedly installed on the L-shaped angle steel bracket 2, and a driving component 25 for intermittently driving the rocker arm 17 is arranged inside the integrated box 24. The driving component 25 includes a driving motor 2501 fixedly installed in the integrated box 24 and a special-shaped block 2502 hinged on the rocker arm 17 and close to its own center point. The output end of the driving motor 2501 is connected to a driving turntable 2503, and a first connecting rod 2504 is eccentrically arranged on the surface of the driving turntable 2503. A special-shaped groove 2505 for the first connecting rod 2504 to pass through is arranged inside the special-shaped block 2502. Through the driving component 25, the driving turntable 2503 is driven to rotate, accompanied by relative movement between the first connecting rod 2504 and the special-shaped groove 2505, so as to realize the linkage between the special-shaped block 2502 and the rocker arm 17, thereby realizing intermittent swinging of the rocker arm 17 around the limiting axis 16.

[0049] It is worth noting that the special-shaped groove 2505 is a semicircular arc structure in the middle and a straight line structure at both ends. The driving turntable 2503 rotates one circle, and the rocker arm 17 swings up and down once around the limit shaft 16 to sow the grain once. By recording the number of rotations of the driving turntable 2503, the number of grain sowings can be obtained, and the single grain sowing amount is the total amount that falls into the sowing groove 19. The single grain sowing amount is multiplied by the number of rotations of the turntable to monitor the grain sowing amount.

[0050] In general, mechanical grain seeding amount monitoring is based on the traditional mechanical structure design. By counting the number of rotations of the driving turntable 2503 and the single seeding amount, the total grain seeding amount can be directly obtained. Compared with the complex CNC monitoring system, the mechanical monitoring method is simpler and more reliable, and is not easily affected by problems such as electronic component failure or sensor inaccuracy. Since the mechanical monitoring method is to perform statistics through the rotation of the turntable, the grain seeding amount can be obtained in real time. There is no need to rely on the data transmission and processing process of electronic equipment or external sensors, and the monitoring results can be obtained instantly, which is convenient for farmers or operators to monitor and adjust the seeding plan in real time. Moreover, compared with the CNC monitoring system, the mechanical monitoring method has lower cost. The design of the mechanical structure is relatively simple, and does not require high investment to purchase and maintain expensive electronic equipment and sensors. This is an economical and feasible monitoring solution for farmers or farms with limited resources.

[0051] Moreover, the mechanical monitoring method can adapt to different types of sowing equipment and grain types. It can adapt to different sowing needs by simply adjusting the design of the turntable and the single sowing amount according to the actual situation. This flexibility makes the mechanical monitoring method more suitable for farms of different sizes and conditions.

[0052] A placement groove 26 is provided in the middle of the first side plate 601 and the second side plate 602. A first installation shaft 27 and a second installation shaft 28 are rotatably provided in the placement groove 26 of the first side plate 601 and the placement groove 26 of the second side plate 602 respectively. A first blocking plate 29 and a second blocking plate 30 are provided on the first mounting shaft 27 and the second mounting shaft 28 respectively. The first blocking plate 29 and the second blocking plate 30 move relative to each other. When the first blocking plate 29 and the second blocking plate 30 are close to each other and abut against each other, a physical barrier is formed between the first blocking plate 29 and the second blocking plate 30. The first material guiding channel 7 of the grain is cut off at the physical barrier, and the first material guiding channel 7 is separated into a closed channel 31 and a circulation channel 32. When the grain discharge channel 13 is in an open state, the grains in the circulation channel 32 can be completely introduced into the grain discharge channel 13. Specifically, the placement groove 26 can be set at appropriate positions of the first side plate 601 and the second side plate 602 as required, and is used to control the amount of grains falling into the sowing groove 19 during a single sowing process.

[0053] The L-shaped angle steel bracket 2 is provided with a placement bracket 33, and the placement bracket 33 is provided with an energy-saving linkage component 34. The energy-saving linkage component 34 is used to realize the linkage between the first blocking plate 29 and the second blocking plate 30 and the intermittently swingable rocker 17. By intermittently driving the rocker 17, the first blocking plate 29 and the second blocking plate 30 are linked. Specifically, when the first blocking plate 29 and the second blocking plate 30 are blocked, the grain discharge channel 13 is in an open state, so that the grains in the circulation channel 32 enter the interior of the grain discharge channel 13; when the first blocking plate 29 and the second blocking plate 30 are opened, the grain discharge channel 13 is in a closed state. At this time, the grains in the blocked channel 31 are supplemented to the interior of the circulation channel 32. The energy-saving linkage component 34 intermittently drives the rocker 17 to link the first blocking plate 29 and the second blocking plate 30; this linkage design can avoid continuous energy consumption in the grain discharge process, thereby achieving energy saving.

[0054] The energy-saving linkage assembly 34 includes a through hole 3401 arranged in the guide plate 5 and close to the placement groove 26 and a limiting sleeve 3402 fixedly installed on the placement bracket 33. A sliding rod 3403 is arranged inside the limiting sleeve 3402. The bottom of the sliding rod 3403 is linked to the swing rod 17 through a second connecting rod 3407. The two ends of the connecting rod 14 are respectively hinged to the sliding rod 3403 and the swing rod 17. An integrated top plate 3404 is arranged on the top of the sliding rod 3403. The integrated top plate 3404 and the guide The integrated top plate 3404 is arranged parallel to the plates 5, and a plurality of extrusion rods 3405 are provided on the upper surface of the integrated top plate 3404. The extrusion rods 3405 pass through the interior of the through hole 3401, and a dislocation inclined surface 3406 is provided on the top side of the extrusion rods 3405. Through the intermittent driving of the rocker arm 17 and under the linkage action of the second connecting rod 3407, the sliding rod 3403 slides up and down inside the limiting sleeve 3402, so that the extrusion rods 3405 on the integrated top plate 3404 slide up and down inside the through hole 3401.

[0055] When the rocker arm 17 swings upward, the second connecting rod 3407 is displaced upward, causing the slide rod 3403 to slide upward inside the limiting sleeve 3402 until the top of the extrusion rod 3405 on the integrated top plate 3404 passes through the top of the through hole 3401, and contacts the outer surfaces of the first blocking plate 29 and the second blocking plate 30 respectively, and under the action of the offset inclined surface 3406, the first blocking plate 29 and the second blocking plate 30 rotate around the first mounting axis 27 and the second mounting axis 28 respectively until the first blocking plate 29 and the second blocking plate 30 tend to be closed.

[0056] When the rocker arm 17 swings downward, the second connecting rod 3407 is displaced downward, causing the sliding rod 3403 to slide downward inside the limiting sleeve 3402, so that the top of the extrusion rod 3405 on the integrated top plate 3404 is lower than the top of the through hole 3401, so that the extrusion rod 3405 is disconnected from the outer surfaces of the first blocking plate 29 and the second blocking plate 30, and with the help of the clockwork spring 22 arranged between the first blocking plate 29 and the first mounting shaft 27 and between the second blocking plate 30 and the second mounting shaft 28, the first blocking plate 29 and the second blocking plate 30 are reset until the inner surface of the first blocking plate 29 is flush with the inner surface of the first side plate 601, and the inner surface of the second blocking plate 30 is flush with the inner surface of the second side plate 602. At this time, the blocking channel 31 and the circulation channel 32 are connected, and the grain in the blocking channel 31 is replenished to the inside of the circulation channel 32.

[0057] Working principle: Before use, the user first installs the grain seeding amount monitoring device on the grain seeder frame and close to the grain seeder frame discharge port position, and then moves the grain seeder frame to make the grain seeder frame travel in the planting area.

[0058] During the movement of the grain seeder frame, the grain passes through the discharge port of the grain seeder frame, enters the interior of the hopper 3, and rolls down to the interior of the eight guide troughs 6 through the outlet at the bottom of the hopper 3. The grain first passes through the second guide channel 8 of the "eight"-shaped structure of the guide trough 6, and uses the guide assembly 9 to arrange the numerous scattered grains in a linear and neat manner and guide them to the interior of the first guide channel 7.

[0059] Then, the power supply of the driving motor 2501 is started to rotate the driving turntable 2503 and cause the swing rod 17 to swing up and down around the limiting shaft 16.

[0060] Specifically, during the upward swing of the swing arm 17, the sowing groove 19 on the support plate 18 contacts and presses the connecting rod 14. At this time, the iron plate 23 is adsorbed on the magnet block, and the connecting rod 14 rises upward in the connecting block 11. The lower surface of the stopper 15 is detached from covering the grain discharge port 10 until the distance between the lower surface of the stopper 15 and the upper surface of the grain discharge port 10 is greater than the particle size of the grain. At this time, the grain discharge channel 13 is in an open state, and the five grains of grain in the circulation channel 32 enter the grain discharge channel 13 under the action of gravity and fall into the sowing groove 19.

[0061] When the swing rod 17 swings downward, the sowing groove 19 on the support plate 18 moves away from the connecting rod 14, causing the connecting rod 14 to slide down due to lack of pressure, and the lower surface of the block 15 covers the grain discharge port 10. At this time, the grain is blocked on one side of the block 15, and the grain discharge channel 13 is in a closed state.

[0062] Then, the next five grains of cereals are added to the interior of the circulation channel 32 under the action of gravity.

[0063] At the same time, the rocker arm 17 is intermittently driven, on the one hand, through the energy-saving linkage assembly 34, so that the first blocking plate 29 and the second blocking plate 30 tend to open, and the grain discharge channel 13 is in a closed state. At this time, the grains in the closed channel 31 are supplemented to the inside of the circulation channel 32.

[0064] On the other hand, the sowing groove 19 on the supporting plate 18 moves downward. When the supporting plate 18 is tilted downward, the five grains in the sowing groove 19 are sown to the ground along the guiding slope at the bottom of the sowing groove 19, thereby achieving the sowing effect.

[0065] It is worth mentioning here that the driving turntable 2503 rotates one circle, and the rocker arm 17 swings up and down once around the limit shaft 16 each time to sow the grain once. By recording the number of rotations of the driving turntable 2503, the number of grain sowings can be obtained, and the single grain sowing amount is the total number of grains falling into the 8 sowing slots 19. In this embodiment, the single grain storage capacity of a single sowing slot 19 is 5 grains. In summary, the driving turntable 2503 rotates one circle, and the total number of 8 sowing slots 19 is 40 grains. The single grain sowing amount is multiplied by the number of rotations of the turntable to monitor the grain sowing amount.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
