The reduction in yield caused by the seeding depth of peanut has always been a problem that farmers are troubled by. Therefore, the control of the seeding depth is of great significance to improve the yield of peanut. The existing peanut seeding machine is to seed first and then to form ridges, and the higher the ridge surface is, the deeper the seeding is.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0041] The purpose of the present application is to provide a peanut seeding machine capable of ridge seeding.

[0042] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments. Embodiments

[0043] Reference Figures 1-6 As shown in the drawings, the peanut seeding machine provided in the embodiments includes a frame 1, a ridging mechanism, a compacting mechanism, an opener 21, a seed box 6, a seed dispenser 5, a covering mechanism 16 and a walking mechanism.

[0044] Specifically, the ridging mechanism is used for ridging, the compacting mechanism is used for compacting and shaping the ridges, the opener 21 is used for opening trenches on the ridges, the seed box 6 is used for containing seeds, the seed dispenser 5 is connected with the seed box 6 and is used for discharging the seeds in the seed box 6, the covering mechanism 16 is used for covering soil, and the ridging mechanism, the compacting mechanism, the opener 21, the seed dispenser 5 and the covering mechanism 16 are all arranged on the frame 1 in sequence along the width direction of the frame 1, and the compacting mechanism is rotatably connected with the frame 1. The walking mechanism is used for realizing the walking of the peanut seeding machine, where the walking specifically refers to the movement of the peanut seeding machine, and the walking mechanism is rotatably arranged on the frame 1. It should be noted that the peanut seeding machine provided in the present application is arranged in the manner as shown in the drawings, where the left-right direction is the width direction of the frame, and the front-rear direction is the length direction of the frame. Figure 2

[0045] The ridging mechanism, the compacting mechanism, the opener 21, the seed box 6, the seed dispenser 5 and the covering mechanism 16 are in one-to-one correspondence with each other, and in the specific use process, the peanut seeding machine sequentially completes the operations of ridging, compacting and shaping the ridges, opening trenches, seeding and covering soil as the peanut seeding machine moves. More specifically, after the ridging mechanism ridges, the compacting mechanism compacts and shapes the ridges, then the opener 21 opens trenches for seeding on the ridges, then the seed dispenser 5 discharges the seeds into the trenches, and finally the covering mechanism 16 covers the seeds with soil, thereby completing the entire seeding process. It can be seen that the seeding manner of the peanut seeding machine provided in the present application is to first ridge and then seed, which has less influence on the germination rate of peanut seeds and subsequent growth than the manner of first seeding and then ridging, and the yield of peanuts is higher.

[0046] As an optional embodiment, as shown in the drawings, the covering mechanism 16 is a covering plate, the covering plate is arranged along the length direction of the frame 1, the position of the covering plate is opposite to the position of the ridges, so as to cover the trenches on the ridges, and the covering plate is connected with the frame 1 through a connecting piece 17.

[0047] As an optional embodiment, as shown in the drawings, the covering mechanism 16 is a covering plate, the covering plate is arranged along the length direction of the frame 1, the position of the covering plate is opposite to the position of the ridges, so as to cover the trenches on the ridges, and the covering plate is connected with the frame 1 through a connecting piece 17.

The ground wheel shaft is rotatably arranged on the frame 1, and the ground wheel shaft and the seed sowing shaft of the seed sowing device 5 are in transmission connection through the intermediate transmission mechanism. The intermediate transmission mechanism is, for example, a chain transmission mechanism, and more specifically, a gearbox 12 is arranged on the frame 1, an input shaft of the gearbox 12 is in transmission connection with the ground wheel shaft through a first chain transmission mechanism 10, and an output shaft of the gearbox 12 is in transmission connection with the seed sowing shaft through a second chain transmission mechanism 11. The specific structure of the seed sowing device 5 belongs to the prior art and is not the focus of the present application, and thus will not be described here.

[0048] As an optional implementation manner, as shown in Figure 1 As shown, the ridging mechanism comprises a first plow blade 13 and a second plow blade 28 which are symmetric to each other and sequentially arranged along the length direction of the frame 1, the first plow blade 13 and the second plow blade 28 are close to each other at the two ends close to the compacting mechanism, the first plow blade 13 and the second plow blade 28 are fixedly connected with the frame 1, and the first plow blade 13 and the second plow blade 28 have a spacing therebetween. The detailed number and specific arrangement manner of the ridging mechanism are determined according to actual needs, one ridging mechanism corresponds to one ridge, and then the first plow blade 13 and the second plow blade 28 form a ridge. Figure 1 The number of the ridging mechanisms is six, and all the ridging mechanisms are arranged in two rows along the width direction of the frame 1.

[0049] Further, as shown in Figures 1-2 As shown, the first plow blade 13 is connected with the frame 1 through a second linear extension mechanism, the second plow blade 28 is connected with the frame 1 through a third linear extension mechanism, and the first linear extension mechanism 3 and the second linear extension mechanism have the same structure, for example, are linear extension mechanisms which can be manually adjusted. More specifically, for example, the second linear extension mechanism comprises a first inner sleeve, a first outer sleeve and a first connecting column, the first inner sleeve is connected with the first plow blade 13, the first outer sleeve is connected with the frame 1, the first outer sleeve is sleeved outside the first inner sleeve and is in sliding connection with the first inner sleeve, the first inner sleeve sequentially has at least two first holes in the height direction thereof, the axis of the first hole is perpendicular to the axis of the first inner sleeve, the first outer sleeve is provided with a second hole, the axis of the second hole is perpendicular to the axis of the first outer sleeve, and the first connecting column passes through the second hole and one of the first holes to realize the connection between the first outer sleeve and the first inner sleeve, and by making the connecting column pass through different positions of the first holes, the axial relative position of the first outer sleeve and the first inner sleeve can be adjusted, and then the height of the first plow blade 13 can be adjusted.

[0050] As an optional implementation manner, as shown inFigure 1 and Figure 4 As shown, the pressing mechanism includes a first pressing wheel 2 and a second pressing wheel 4 arranged symmetrically along the length of the frame 1. Both the first pressing wheel 2 and the second pressing wheel 4 are conical structures, with their small ends facing each other. Both the first pressing wheel 2 and the second pressing wheel 4 are rotatably connected to the frame 1. The first pressing wheel 2 is positioned opposite to the first plow blade 13, and the second pressing wheel 4 is positioned opposite to the second plow blade 28. One pressing mechanism corresponds to one row, and the number of pressing mechanisms is determined according to actual needs. When there are two or more pressing mechanisms, the peanut planter also includes a central shaft 40. All pressing mechanisms are arranged sequentially along the axial direction of the central shaft 40. Each first pressing wheel 2 and each second pressing wheel 4 is fitted onto the central shaft 40 and is drivenly connected to the central shaft 40, for example, by a key connection, to rotate synchronously with the central shaft 40. Both ends of the central shaft 40 are rotatably connected to the frame 1.

[0051] Furthermore, such as Figures 4-5 As shown, the trencher 21 is connected to the frame 1 via a third linear telescopic mechanism, which is, for example, a manually adjustable linear telescopic mechanism. More specifically, for example, the third linear telescopic mechanism includes a second inner sleeve, a second outer sleeve, and a second connecting post. The trencher 21 is connected to the second inner sleeve, and the second outer sleeve is connected to the frame 1. The second outer sleeve is fitted over the second inner sleeve, and the two are slidably connected. The second inner sleeve has at least two third openings sequentially along its height direction, with the axis of the third opening perpendicular to the axis of the second inner sleeve. The second outer sleeve has a fourth opening, with the axis of the fourth opening perpendicular to the axis of the second outer sleeve. The second connecting post passes through both the fourth opening and one of the third openings to connect the second outer sleeve and the second inner sleeve. By having the second connecting post pass through the third openings at different positions, the axial relative position of the second outer sleeve and the second inner sleeve can be adjusted, thereby adjusting the height of the trencher 21. Example

[0052] like Figures 4-5 As shown, the difference between this embodiment and Embodiment 1 is that the peanut planter provided in this embodiment also includes a ridge-protecting mechanism 22 for ridge protection. The ridge-protecting mechanism 22 is connected to the frame 1, and the furrow opener 21 is positioned opposite to the ridge-protecting mechanism 22. In the length direction of the frame 1, both the furrow opener 21 and the ridge-protecting mechanism 22 are located between the first press wheel 2 and the second press wheel 4. The ridge-protecting mechanism 22 can protect the ridges during furrow opening, thereby preventing damage to the ridge shape during furrow opening. At the same time, the ridge-protecting mechanism 22 also has a certain ridge-pressing effect.

[0053] As an alternative implementation method, such as Figure 4The furrow opener 21 passes through the ridge protection mechanism 22, the furrow opener 21 is fixedly connected with the frame 1, and the furrow opener 21 is connected with the ridge protection mechanism 22. Preferably, in order to facilitate installation, the furrow opener 21 is hingedly connected with the ridge protection mechanism 22. For example, by providing a mounting sleeve 27 on the furrow opener 21, by mounting a pin shaft in the mounting sleeve 27, and by connecting the pin shaft with a first connecting seat 29 on the ridge protection mechanism 22, the hinged connection of the furrow opener 21 with the ridge protection mechanism 22 is achieved.

[0054] As an optional embodiment, as shown in Figure 6 The ridge protection mechanism 22 includes a ridge protection plate, the shape of the ridge protection plate matches the shape of the two sides of the ridge and the surface of the ridge, the ridge protection mechanism 22 is oppositely arranged with the seed box 6 and the soil covering mechanism 16, and the soil covering mechanism 16 is fixedly connected with the ridge protection mechanism 22.

[0055] As an optional embodiment, as shown in Figure 3 and Figure 5 The seed metering device 5 is connected with a seed metering channel 19, the outlet of the seed metering channel 19 is oppositely arranged with the ridge protection mechanism 22, the position of the ridge protection mechanism 22 opposite to the outlet of the seed metering channel 19 is provided with a seed dropping channel 31, and the seed dropping channel 31 is located between the soil covering mechanism 16 and the furrow opener 21. Embodiment

[0056] As shown in Figure 4 The difference between the present embodiment and the second embodiment is that, in order to facilitate the adjustment of the seeding depth, the peanut seeding machine further includes a connecting mechanism and a first linear extension mechanism 3, the first linear extension mechanism 3 is, for example, a push rod motor, and the specific number of the first linear extension mechanism 3 is determined according to actual needs. When the number of the first linear extension mechanism 3 is at least two, all the first linear extension mechanisms 3 are sequentially arranged along the length direction of the frame 1. The connecting mechanism includes a first connecting frame 24 and a second connecting frame 25, one end of the first connecting frame 24 is connected with the second connecting frame 25, and the angle between the two is an obtuse angle. The first connecting frame 24 is hingedly connected with the frame 1, the first linear extension mechanism 3 is hingedly connected with the frame 1, the first linear extension mechanism 3 is hingedly connected with the second connecting frame 25, the pressing mechanism is rotationally connected with the first connecting frame 24, and the furrow opener 21 is fixedly connected with the second connecting frame 25. As an optional embodiment, the number of the connecting mechanism is two, the two connecting mechanisms are arranged at the two ends of the length direction of the frame 1, and the two second connecting frames 25 of the two connecting mechanisms are connected through a third connecting frame 23. More specifically, the two ends of the center shaft 40 of the pressing mechanism are hingedly connected with the two first connecting frames 24, respectively, and each third linear extension mechanism is fixedly connected with the third connecting frame 23, so as to achieve the fixed connection of the furrow opener 21 with the second connecting frame 25.

[0057] In practical use, when the peanut planter is placed on a level surface, the second connecting frame 25 is horizontally positioned. As the first linear telescopic mechanism 3 extends and retracts vertically, the second connecting frame 25 moves accordingly. Since the pressing mechanism and the furrow opener 21 are both connected to the second connecting frame 25, and the ridge-protecting mechanism 22 is indirectly connected to the second connecting frame 25 via the furrow opener 21, when the second connecting frame 25 moves, the pressing mechanism, furrow opener 21, and ridge-protecting mechanism 22 move synchronously, thereby adjusting the sowing depth. Furthermore, during sowing, the pressing mechanism, furrow opener 21, and ridge-protecting mechanism 22 move together in a contour-following motion, effectively ensuring the consistency of sowing depth and the integrity of the ridge shape.

[0058] It should also be noted that as the first linear telescopic mechanism 3 extends and retracts, the angle between the second connecting frame 25 and the first linear telescopic mechanism 3, as well as the angle between the first connecting frame 24 and the frame 1, all change accordingly. It is understandable that the pressure applied to the soil by the compaction mechanism of the first linear telescopic mechanism 3 and the pressure applied to the soil by the ridge protection mechanism 22 also change accordingly. Example

[0059] like Figures 7-9 As shown, the difference between this embodiment and Embodiment 3 is that the peanut planter provided in this embodiment further includes a first buffer mechanism and a second buffer mechanism. The first linear telescopic mechanism 3 is hinged to the frame 1 through the first buffer mechanism, and the ridge protection mechanism 22 is connected to the frame 1 through the second buffer mechanism. Under the action of the first buffer mechanism and the second buffer mechanism, when the ridge protection mechanism 22, the furrow opener 21, and the pressing mechanism are subjected to external forces, buffering can occur, avoiding damage to the ridge protection mechanism 22, the furrow opener 21, and the pressing mechanism caused by external forces.

[0060] As an alternative implementation method, such as Figures 6-8 As shown, the first buffer mechanism includes a first connecting rod 32, a second connecting rod 33, and a first elastic element 26. The first connecting rod 32 is hinged to the first linear telescopic mechanism 3, and the second connecting rod 33 is hinged to the second connecting frame 25. The first connecting rod 32 and the second connecting rod 33 are connected by the first elastic element 26, which is, for example, a spring. More specifically, a fixed seat 18 is provided on the third connecting frame 23, and the second connecting rod 33 is hinged to the fixed seat 18.

[0061] As an alternative implementation method, such as Figure 9As shown, the second buffer mechanism includes a middle connecting rod 34, a second elastic element 35, a third elastic element 36, a separator 37, a first limiting element 38, and a second limiting element 39. The intermediate connecting rod 34 is hinged to the ridge protection mechanism 22. The second elastic element 35 and the third elastic element 36 are both sleeved on the intermediate connecting rod 34 and are arranged sequentially along the axial direction of the intermediate connecting rod 34. The separator 37 is movably sleeved on the intermediate connecting rod 34 and is located between the second elastic element 35 and the third elastic element 36. The opposite ends of the first elastic element 26 and the second elastic element 35 are distributed at both ends of the separator 37 and abut against each other. The separator 37 is rotatably connected to the frame 1, and the rotation axis of the separator 37 is perpendicular to the axis of the intermediate connecting rod 34. The first limiting element 38 and the second limiting element 39 are both arranged on the intermediate connecting rod 34. The end of the second elastic element 35 away from the separator 37 abuts against the first limiting element 38, and the end of the third elastic element 36 away from the separator 37 abuts against the second limiting element 39. The second elastic element 35 and the third elastic element 36 are, for example, springs. The first limiting member 38 is, for example, a first limiting pin, and the second limiting member 39 is, for example, a second limiting pin. The ridge protection mechanism 22 is provided with a second connecting seat 30, and the intermediate connecting rod 34 is hinged to the second connecting seat 30.

[0062] Furthermore, the intermediate connecting rod 34 is provided with at least two first limiting holes along its own axis, and a first limiting member 38 is disposed in one of the first limiting holes to be mounted on the intermediate connecting rod 34. The intermediate connecting rod 34 is provided with at least two second limiting holes along its own axis, and a second limiting member 39 is disposed in one of the second limiting holes to be mounted on the intermediate connecting rod 34. The number of second limiting holes is determined according to actual needs. By placing the first limiting member 38 in the first limiting holes at different positions, the buffering force provided by the second elastic member 35 can be adjusted. By placing the second limiting member 39 in the second limiting holes at different positions, the buffering force provided by the third elastic member 36 can be adjusted. Example

[0063] like Figures 1-2 As shown, the difference between this embodiment and Embodiment 1 is that the peanut planter also includes a drip irrigation mechanism. The drip irrigation mechanism is rotatably mounted on the frame 1. The ridging mechanism, compaction mechanism, furrow opener 21, seed metering device 5, soil covering mechanism 16, and drip irrigation mechanism are arranged sequentially along the width of the frame 1. With this configuration, the peanut planter provided by the present invention also has a drip irrigation function, enabling drip irrigation operation after soil covering is completed.

[0064] In one optional implementation, the drip irrigation mechanism includes a support frame 9, a guide sleeve 14, a support shaft 8, and at least two retaining rings 7. The support frame 9 is connected to the frame 1, and the two are preferably detachably connected, for example, by bolts. Each retaining ring 7 is fitted onto the support shaft 8 and is fixedly connected to the support shaft 8. Both ends of the support shaft 8 are rotatably connected to the support frame 9. A space for accommodating the drip irrigation pipe is formed between any two adjacent retaining rings 7. The inside of the guide sleeve 14 is used to install the outlet end of the drip irrigation pipe.

[0065] The number of retaining rings 7 depends on actual needs. Two retaining rings 7 correspond to one row. The distance between the two retaining rings 7 is, for example, equal to the width of the row. In actual use, the drip irrigation pipe is wound around the support shaft 8, and the water outlet end of the drip irrigation pipe is placed inside the guide sleeve 14. The guide sleeve 14 plays a guiding and positioning role, and the guide sleeve 14 can keep the water outlet end of the drip irrigation pipe vertically downward. Figure 1 The number of center rings 7 is specifically 6. Example

[0066] like Figure 3 As shown, the difference between this embodiment and Embodiment 2 is that the peanut planter also includes a terrain acquisition device 20 for collecting terrain data, which is mounted on the frame 1. The terrain acquisition device 20 is, for example, a lidar sensor. The terrain acquisition device 20 can collect real-time data on the flatness of the ridge surface to detect whether the ridge protection mechanism 22 is in contact with the ridge surface, thereby determining the planting depth.

[0067] Furthermore, the peanut planter also includes a controller. The terrain acquisition device 20 is communicatively connected to the controller to transmit the acquired terrain information to the controller. The controller is connected to the first linear telescopic mechanism 3 to adjust the telescopic amount of the first linear telescopic mechanism 3 according to the received terrain information, thereby realizing the adjustment of the planting depth, the pressure provided by the ridge guard plate, and the pressure provided by the press wheel. This configuration enables dynamic adjustment of the ridging effect.
