Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting machinery, and in particular to an intelligent taro planting and film covering integrated machine. Background Art

[0002] Taro grows vigorously, the plants are relatively tall, and the leaf area index is large, so it is necessary to make full use of the land and space. Figure 1 As shown in the figure, the best planting method and density are: high ridge planting, ridge width 130-135cm (including furrows), ridge height 20-25cm; double row planting, large row 65-70cm, small row 40-45cm, plant spacing 35-40cm, every 667m 2 Plant 2,800 to 3,000 plants. Taro corms have the habit of growing upwards, so they should be planted deeply. The planting depth should be about 10 cm. The temperature is low during planting, so we should take adequate cold-proof and heat-insulating measures. Mulching is the best way. After planting back into the hole, cover the bed surface with a 140 cm wide agricultural film, which can not only keep warm, but also keep moisture and prevent weeds. About 20 days after sowing, the taro sprouts will emerge from the ground. At this time, holes should be opened in time to allow the taro sprouts to grow naturally. The holes should be small rather than large. The ridge width of the taro field is generally 300 mm, the ridge height is 150 mm, the row spacing is 800 mm, and the plant spacing is 300 mm.

[0003] At present, most taro planting is done manually, which consumes a lot of manpower and has low planting efficiency.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments.

[0035] The utility model embodiment provides an intelligent taro planting and film covering integrated machine, such as Figure 2 As shown, the intelligent taro planting and film covering machine includes a chassis 1, a driving wheel assembly 2, a furrow opener 3, a planting mechanism 4, a soil covering mechanism 5 and a film covering mechanism 6, the driving wheel assembly 2 is connected to the chassis 1, and the furrow opener 3, the planting mechanism 4, the soil covering mechanism 5 and the film covering mechanism 6 are installed on the chassis 1 in sequence along the moving direction of the driving wheel assembly 2.

[0036] In the specific implementation, the driving wheel assembly 2 is made to move in a set direction, wherein the set direction is usually determined by the specific taro planting terrain. During the movement of the driving wheel assembly 2, the furrow opener 3 will first open the furrow, and then the taro seeds will be sown in the furrow body through the planting mechanism 4. The soil covering mechanism 5 behind the planting mechanism 4 will move the soil produced by the previous excavation of the furrow opener 3 to the furrow body where the taro seeds have been sown, so as to achieve soil covering. After the soil covering is completed, the subsequent film covering mechanism 6 will cover the soil body of the planted taro seeds with a layer of ground film, so that the planting and film covering of taro can be efficiently realized.

[0037] In an exemplary embodiment, when the driving wheel assembly 2 is driven by electric energy, the intelligent taro planting and film covering integrated machine also includes an energy supply mechanism, such as Figure 2 As shown, the energy supply mechanism includes a solar panel 7 and a battery panel. The solar panel 7 and the battery panel (not shown in the figure) are both arranged at the upper end of the chassis 1. The solar panel 7 is connected to the battery panel by wire to charge the battery panel, and the battery panel is connected to the driving wheel panel 2 by wire to provide electrical energy to the driving wheel panel.

[0038] The solar energy component 7 may include two solar panels, which are fixed obliquely on both sides of the upper end of the chassis 1. The battery component may be a power lithium battery, and the two solar panels are used to supplement the power lithium battery with electric energy.

[0039] It is understandable that when the driving wheel assembly 2 is driven by electric energy, the solar energy assembly 7 is not necessary, and only one battery assembly may be provided to provide an energy source for the driving wheel assembly 2 .

[0040] In an exemplary embodiment, Figure 3 As shown, the driving wheel assembly 2 includes two driving units 21, and the two driving units 21 are symmetrically arranged about the axis of the chassis 1. The driving unit 21 includes a walking wheel 211, a motor 212, a sprocket assembly 213 and a rotating shaft 214. The rotating shaft 214 is rotatably arranged below the chassis 1, and the rotating shaft 214 is coaxially connected to the walking wheel 211. The output end of the motor 212 is connected to the rotating shaft 214 through the sprocket assembly 213.

[0041] The driving wheel assembly 2 uses two driving units 21 arranged in front of the chassis 1 and symmetrically about the chassis 1. The power comes from the motor 212. When the motor 212 is working, the power is transmitted to the rotating shaft 214 through the sprocket assembly 213. The rotating shaft 214 rotates to make the walking wheel 211 move on the ground.

[0042] In a specific embodiment, if Figure 4As shown, the specific structural composition of the sprocket assembly 213 is provided, and the sprocket assembly 213 includes a first sprocket 2131, a second sprocket 2132 and a chain 2133, the first sprocket 2131 is arranged at the output end of the motor 212, the first sprocket 2131 is connected to the second sprocket 2132 through the chain 2133, and the second sprocket 2132 is arranged on the rotating shaft 214.

[0043] It should be noted that the driving wheel assembly 2 is not limited to being driven by electric energy, but can also be driven by petroleum energy. For example, when driven by petroleum energy, the motor can be replaced by a gasoline engine or a diesel engine.

[0044] In an exemplary embodiment, Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, the planting mechanism 4 includes a planting box 41, a first conveying sprocket 42, a second conveying sprocket 43, a conveying chain 44, a conveying trough plate 45, a conveying motor 46 and a tuber carrying plate 47. The upper end of the planting box 41 is open, and the conveying trough plate 45 is installed on one side of the planting box 41 and cooperates with the planting box 41 to form a first space 48 and a second space 49 on the inner and outer sides of the planting box. The first conveying sprocket 42 and the second conveying sprocket 43 are respectively rotatably installed on the conveying trough plate 45, and the first conveying sprocket 42 or the second conveying sprocket 43 is connected to the conveying motor 46. The conveying chain 44 connects the first conveying sprocket 42 and the second conveying sprocket 43, and under the drive of the conveying motor 46, the conveying chain 44 operates in the first space 48 and the second space 49, and the tuber carrying plate 47 is set to be multiple and evenly distributed on the conveying chain 44.

[0045] The working principle of the implantation mechanism 4 is as follows:

[0046] The planting box 41 is used to temporarily store taro seeds to be sown. During the movement of the intelligent taro planting and film covering machine, the transmission motor 46 works to rotate the first transmission sprocket 42, and the transmission chain 44 is installed on the first transmission sprocket 42 and the second transmission sprocket 43 to form a closed loop. Therefore, the transmission chain 44 will run up and down in the first space 48 and the second space 49. At this time, the taro seeds to be sown are located in the first space 48. The tuber carrying plate 47 can take out a taro seed during the operation of the transmission chain 44, and arrive at the second space 49 with the operation of the transmission chain 44 and finally pour out the taro seeds it carries into the excavated ditch, so as to carry out a cycle, and realize the automatic planting of taro seeds.

[0047] It should be noted that since the conveying chain 44 is mounted on the first conveying sprocket 42 and the second conveying sprocket 43 to form a closed loop, a through hole 410 should be provided at the bottom of the planting box 41 to allow the conveying chain 44 and the tuber bearing plate 47 mounted on the conveying chain 44 to pass through. In the through hole 410, the size should ensure that the taro seeds cannot fall from the left and right sides of the conveying chain 44, that is, the distance between the conveying chain 44 and the through hole 410 should be as small as possible. The taro seeds may fall from the part of the through hole 410 that allows the tuber bearing plate 47 to pass through. At this time, the fallen taro seeds will be caught by the unloaded tuber bearing plate 47, so as to ensure that the taro seeds in the planting box 41 will not fall out of the through hole 410, but will be sown under the load of the tuber bearing plate 47.

[0048] In this embodiment, Figure 7 As shown, in order to prevent taro seeds from falling from the portion of the through hole 410 that allows the tuber carrying plate 47 to pass through, a plurality of elastic baffles 411 are provided corresponding to the portion of the through hole 410 that allows the tuber carrying plate 47 to pass through. The elastic baffles 411 can only be opened by pushing upward, that is, when the conveying chain 44 is running, the elastic baffles 411 are opened by the pushing of the tuber carrying plate 47 to allow the tuber carrying plate 47 to pass through. After the tuber carrying plate 47 passes through, the elastic baffles 411 return to their original positions under their own elastic force, thereby preventing taro seeds from falling out.

[0049] In a specific embodiment, if Figure 8 As shown, the tuber carrier plate 47 includes a bottom plate 471, a plurality of pillars 472 and a circular plate 473. The bottom plate 471 is fixed on the conveying chain 44, and the upper end of the bottom plate 471 is connected to the circular plate 473 through a plurality of pillars 472. The tuber carrier plate 47 serves to load taro seeds. Usually, one tuber carrier plate 47 is loaded with one taro seed.

[0050] In an exemplary embodiment, Fig. 9 As shown, the soil covering mechanism 5 comprises a first soil covering plate 51, a second soil covering plate 52, a third soil covering plate 53 and a fourth soil covering plate 54 which are connected in a slanting manner in sequence, and the first soil covering plate 51, the second soil covering plate 52, the third soil covering plate 53 and the fourth soil covering plate 54 are fixed to the lower end of the chassis 1. By using four soil covering plates connected in a slanting manner in sequence, the taro seeds after sowing can be better buried.

[0051] In an exemplary embodiment, Figure 5As shown, the film covering mechanism 6 includes two first soil leveling shovels 61, a film clamp 62, a film pressing rod wheel 63 and two second soil leveling shovels 64, wherein the two first soil leveling shovels 61 and the two second soil leveling shovels 64 are symmetrically installed on both sides of the chassis, and on the chassis 1, the two first soil leveling shovels 61, the film clamp 62, the film pressing rod wheel 63 and the two second soil leveling shovels 64 are installed in sequence along the traveling direction of the driving wheel assembly.

[0052] The two first soil leveling shovels 61 are used to dig a small pit on both sides of the land where taro seeds are sown, and the ground film clamp 62 is used to clamp one end of the ground film. The other end of the ground film is pre-fixed to the ground. The fixing method includes but is not limited to using soil and stones to press and cover the other end of the ground film. As the all-in-one machine moves, the ground film unfolds and covers the ground. Finally, two second soil leveling shovels 64 are used to cover the soil dug out by the two first soil leveling shovels 61 on both sides of the ground film to ensure the coverage stability of the ground film.

[0053] In general, the film covering mechanism 6 is designed with four soil leveling shovels. Two first soil leveling shovels 61 are used to turn out part of the soil at both ends of the ridge slope before laying the ground film. After the ground film is laid, two second soil leveling shovels 64 are used to cover the turned soil on both sides of the ground film to prevent the natural external force factors from destroying the covered ground film. The four soil leveling shovels are made of manganese steel with high hardness, which is not easy to deform and has good support. The entire film covering mechanism is designed to be integrated, and the left and right soil leveling shovels are welded to form a stable whole in the back half. The integrated film covering structure integrates multiple functional units together, avoiding structural problems caused by connecting the parts, saving space, and making the film covering mechanism structure more compact.

[0054] In a specific embodiment, if Figure 3 As shown, the ground film clamp 62 includes a fixed rod 621, a roller 622 and a bracket 623. The bracket 623 is provided in two and the two brackets 623 are symmetrically fixed on the chassis 1. The two ends of the fixed rod 621 are provided on the two brackets. The roller 622 is rotatably provided on the fixed rod 621, and the roller is used as a carrier of the ground film.

[0055] In a specific embodiment, if Figure 3 As shown, the film pressing rod wheel 63 is a wheel-like structure, with large wheels at both ends compacting the ground film on both sides of the ridge, and a long rod compacting the ground film on the ridge, and the two cooperate to limit the position of the ground film on the ridge, making the ground film laying process more coherent and smooth. Specifically, the film pressing rod wheel 63 includes a film pressing shaft 631, a pressing wheel 632 and a support member 633, and the support member 633 is provided in two and the two support members 633 are symmetrically fixed on the chassis 1, and the two ends of the film pressing shaft 631 are rotatably provided on the two support members 633, and the pressing wheel 632 is coaxially connected to the film pressing shaft 631.

[0056] In this embodiment, Figure 6 As shown, a hole opener 634 is provided on the film pressing shaft 631. As the film pressing rod rotates, the hole opener 634 opens holes on the ground film at a fixed distance, making it easier for taro to germinate.

[0057] For example, as shown in Table 1, the overall parameters of the intelligent taro planting and film covering machine are shown.

[0058] Table 1 Overall parameters

[0059] Dimensions (mm) 1197×957×949 Structural mass (kg) 105.7 Working speed (km / h) 2-5 Seed box volume (L) 60 Basic row spacing (mm) 800 Motor power(W) 750

[0060] The power consumption of the intelligent taro planting and film covering machine is composed of the driving unit moving forward, the furrow opener breaking the soil, the covering device covering the soil, the soil leveling shovel covering the soil, the film covering rod removing the film and the friction loss of the transmission system. Calculated according to the power formula:

[0061] F=F q +F k +F f +F z +F g +F m

[0062] Where: F is the total power consumption of the whole machine; F q F is the power consumption of driving the unit forward; k F is the power consumption of the trench opener when breaking the soil; f F is the power consumption of the soil cover device; z F is the power consumption of soil shoveling and covering; g F is the power consumption of the film-laying rod when producing film; m The power consumption is the power consumption of transmission and friction. In the total power consumption of the whole machine, the power consumption of the trench opener breaking the soil and the power loss of the driving unit forward are the main ones, accounting for more than 80% of the total power consumption.

[0063] Refer to the formula for calculating and analyzing the power consumption of trenching in the "Agricultural Machinery Design Manual". This formula meets the requirements for calculating power. The power consumption of trenching is calculated by selecting various parameters of the intelligent taro planting and film covering machine and different correction coefficients:

[0064]

[0065] In the formula: represents the furrowing power of the furrow opener: KW; h is the furrowing depth of the furrow opener: cm; v is the forward speed of the machine: m / s; d is the furrowing width of the furrow opener: m; K is the furrowing resistance: N / cm 2 .

[0066] The intelligent taro planting and film covering machine needs to overcome various operating resistances during field operation, including air resistance, ground rolling resistance, and internal resistance of the transmission system. Since the influence of air resistance on the operation of the machine is small and difficult to calculate, it is omitted here. Therefore, the power formula consumed by driving the machine forward is:

[0067] F q =f mgv×10 -3

[0068] Where: f is the tire rolling friction coefficient; m is the mass of the whole machine: kg.

[0069] The driving wheel assembly is driven by two rubber wheels. Since the row spacing of the general taro planting mode is 800mm, and the ditch width is generally 300mm or even smaller, wheels are used as the travel mode. Since the ground pressure distribution requirements in the ditch are low, the use of wheels can have better passability than crawlers.

[0070] In order to increase the grip of the traveling tire, multiple protrusions are designed on the traveling wheel to improve the grip and provide sufficient traction. The tread pattern of the traveling tire usually adopts a deep and wide pattern design, which can effectively increase the contact area between the tread and the ground and improve the grip. The protrusions and grooves in the pattern design can effectively drain water and prevent the tire from slipping. The tread material of the traveling tire is usually made of wear-resistant and cut-resistant rubber material, and the hardness is controlled appropriately, which not only ensures durability but also provides good grip. Such a design can ensure that the tire can perform well in various terrains and working conditions.

[0071] Regarding the planting mechanism, through data review, it is calculated that the weight of a piece of taro seed is about 0.1kg. There are 16 bearing plates on the transmission mechanism. At the same time, other factors such as the weight of the chain and the weight of the taro bearing plate need to be considered. It is estimated that the required traction force is about 75N. For reliability considerations, the traction force required for the transmission chain belt to rotate is 90N, which is 120% of the original, recorded as F. According to the preset machine travel speed and considering the need for machine action coordination, the speed of the transmission chain is controlled at 80mm / s~120mm / s, and the average is 100mm / s, recorded as v. According to the power calculation formula:

[0072] P=Fv

[0073] The power on the transmission shaft is calculated to be P = 9W. The mechanical efficiency n1 is set to 0.75, and the transmission efficiency of the motor is set to n2 = 0.8. The motor power can be calculated, that is,

[0074]

[0075] It can be calculated that P1 = 15W, so a 15W 42 stepper motor is selected as the transmission motor of the implant mechanism.

[0076] In order to prevent the stepper motor from losing steps, stalling, or losing steps during operation, which may cause the taro seeds to fall out of the carrier plate, we introduced a gradient acceleration and deceleration algorithm to deal with such problems.

[0077] In order to maximize energy efficiency and reduce soil compaction, the core zinc opener is used. Fig.10 When working, the core zinc enters the soil to open the trench, and the two side plates separate the soil to form a seed trench. The core zinc type trench opener has a larger trenching width and good soil penetration performance, but the working resistance is relatively large.

[0078] Finally, SolidWorks Simulation was used to perform finite element analysis on the walking mechanism frame (i.e. chassis 1). After applying the set load, the stress cloud diagram of the frame was obtained (e.g. Fig.11 As shown in the figure, there is stress concentration at the horizontal bar of the frame. The maximum stress intensity of the frame is 5.350e 7 (N / m 2 ), within the strength range of the materials selected for the frame, the frame structure strength meets the design requirements.

[0079] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
