Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural machinery technology, and in particular to a yam and bean planter. Background Technology
[0002] Yam, also known as Dioscorea opposita or Dioscorea glutinosa, has the effects of aiding digestion, reducing night sweats, and stopping diarrhea.
[0003] Currently, yam cultivation faces the following technical challenges: Yam cultivation requires deep, loose sandy loam or light loam soil, ideally slightly acidic to neutral. Planting yams necessitates digging cultivation trenches, typically about 1 meter apart, 0.6-1.0 meters deep, and 25 centimeters wide. Clay soil and hard black soil are unsuitable for yam cultivation. These soil conditions severely limit the planting area for yams.
[0004] Therefore, there is an urgent need to design a yam planting machine to overcome the limitations imposed by soil conditions during yam cultivation. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to provide a yam bean planter that can effectively solve the soil condition limitations when planting yams, so that yams can also be planted in clay soil or black soil.
[0006] The present invention solves the above-mentioned technical problems through the following technical means:
[0007] The yam bean planter of the present invention includes a walking mechanism, a ditching mechanism, a soil and filler mixing mechanism, and a sowing mechanism. The ditching mechanism, soil and filler mixing mechanism, and sowing mechanism are all mounted on the walking mechanism. The ditching mechanism is used to dig cultivation trenches approximately 15 cm wide and 0.6–1.0 m deep in the field, and to transfer the soil removed during ditching to the soil and filler mixing mechanism. The soil and filler mixing mechanism is used to mix the soil removed during ditching with filler material and then backfill the cultivation trenches. The sowing mechanism is used to sow yam beans into the backfilled cultivation trenches. Preferably, the width of the cultivation trench is 13–16 cm.
[0008] Furthermore, the trenching mechanism includes a support frame, a drive unit, a drive sprocket, a driven sprocket, and a transmission chain sleeved on the drive sprocket and driven sprocket. The drive sprocket is drively connected to the power output shaft of the drive unit. Multiple buckets are arranged side-by-side along the length of the transmission chain. The drive unit and drive sprocket are mounted on the support frame. It also includes a swing arm and a telescopic cylinder. One end of the swing arm is free, and the other end is hinged to the support frame via a hinge shaft. The driven sprocket is located at the free end of the swing arm, and the drive sprocket is located on the hinge shaft. The two ends of the telescopic cylinder are respectively hinged to the swing arm and the support frame. Alternatively, the sprockets and transmission chain on the trenching mechanism can be replaced by pulleys and a conveyor belt. The telescopic cylinder can be a hydraulic telescopic cylinder or an electric telescopic cylinder.
[0009] Furthermore, the soil and filler mixing mechanism includes a mixing box, on which filler and soil inlets are provided. The filler and soil inlets are located below the drive sprocket. When the bucket is driven by the transmission chain to the top of the filler and soil inlets, the soil in the bucket can be poured into the filler and soil inlets.
[0010] Furthermore, the mixing chamber is equipped with a mixing chamber and a screw conveyor pump located at the bottom of the mixing chamber. The mixing chamber is equipped with a mixer. The screw conveyor pump includes a motor-driven screw and a cylindrical conveying pipe. The axial directions of the screw and the conveying pipe are parallel to the length direction of the cultivation ditch. The soil and filler mixing mechanism also includes discharge pipes. Multiple discharge pipes are provided. The top openings of the multiple discharge pipes are arranged sequentially along the bottom of the conveying pipe, and the bottom openings of the multiple discharge pipes are arranged sequentially along the direction of the cultivated ditch.
[0011] Furthermore, it also includes a filler crushing mechanism, which is located above the soil and filler mixing mechanism. The filler crushing mechanism includes a straw crushing chamber, with a straw feeding port at the top and a straw discharge pipe at the bottom. The straw discharge pipe is connected to the filler and soil inlets on the mixing box.
[0012] Furthermore, the sowing mechanism includes a seed box and a yam seed conveying mechanism. The lower part of the seed box is funnel-shaped and has a vertically arranged vertical sidewall. The yam seed conveying mechanism includes a conveyor belt and a drive mechanism for driving the conveyor belt. The drive mechanism includes a drive motor, a driving pulley, and a driven pulley. The driving pulley is connected to the power output shaft of the drive motor. Multiple seed holders are arranged in parallel along the length of the conveyor belt. The bottom of the seed box has a channel that allows the conveyor belt and seed holders to pass through. The driving pulley and the driven pulley are respectively located above and below the vertical sidewall. The conveyor belt is sleeved on the driving pulley and the driven pulley. The conveyor belt surrounds the vertical sidewall inside the conveyor belt. One end of the conveyor belt passes through the channel and extends upward along the inner side of the vertical sidewall to the driving pulley.
[0013] Furthermore, the seeding mechanism also includes baffles and guide troughs for guiding seeds to the ground. The baffles are located outside the seed box and on both sides of the conveyor belt. The bottom of the guide trough is located behind the discharge pipe. The two side walls of the top of the guide trough are respectively connected to the baffles on both sides of the conveyor belt. Soil covering plates are provided on the left and right sides behind the bottom of the guide trough.
[0014] Furthermore, it also includes a fertilization device, which includes a fertilizer tank and a fertilizer discharge pipe located at the bottom of the fertilizer tank. The fertilizer discharge pipe is equipped with an electromagnetic valve that can control the amount of fertilizer discharged per unit time. The bottom opening of the fertilizer discharge pipe is connected to the top end of the conveying pipe, or the bottom opening of the fertilizer discharge pipe is connected to a discharge pipe near the end of the conveying pipe.
[0015] Furthermore, the walking mechanism is equipped with a speed sensor, and also includes a controller and a power supply. The controller is connected to the speed sensor, screw conveyor pump, mixer, solenoid valve, and drive motor circuit, respectively.
[0016] The present invention has the following beneficial effects:
[0017] 1) The yam bean planter of the present invention includes a walking mechanism, a ditching mechanism, a soil and filler mixing mechanism, and a sowing mechanism. The ditching mechanism is mounted on the walking mechanism and is used to dig cultivation trenches approximately 15 cm wide and 0.6–1.0 m deep in the field, and to transfer the soil removed during ditching to the soil and filler mixing mechanism. The soil and filler mixing mechanism is used to mix the soil removed during ditching with filler material and then backfill the cultivation trenches. The sowing mechanism is used to sow yam beans into the backfilled cultivation trenches. The yam bean planter of the present invention effectively solves the soil condition limitations in yam cultivation by mixing the soil removed during ditching with filler material such as straw and then backfilling it, enabling yams to be planted in clay soil or black soil.
[0018] 2) The yam bean planter of the present invention also improves the ditching mechanism, so that the soil taken out during ditching can be smoothly transported to the soil and filler mixing mechanism.
[0019] 3) The yam bean planter of the present invention also improves the fertilization device so that fertilizer can be added to a suitable depth when backfilling the cultivation trench. Attached Figure Description
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Figure 1 This is a three-dimensional structural diagram of the yam and bean planter of the present invention;
[0022] Figure 2 This is a side view of the yam and bean planter of the present invention.
[0023] Figure 3 This is a rear view of the yam and bean planter of the present invention. Detailed Implementation
[0024] The present invention will now be described in detail with reference to the accompanying drawings:
[0025] like Figure 1-3 As shown: The yam bean planter in this embodiment includes a walking mechanism, a ditching mechanism 3, a soil and filler mixing mechanism 4, and a planting mechanism 5. It includes a frame 1 and wheels 2 mounted on the frame 1. The ditching mechanism 3 is located near the front end of the walking mechanism, as shown below. Figure 2 As shown in the figure, the right side of the walking mechanism is the front end, and the left side is the rear end. The trenching mechanism 3 includes a support frame 30, a drive device 31, a drive sprocket 32, a driven sprocket 33, and a transmission chain 34 sleeved on the drive sprocket 32 and the driven sprocket 33. The drive sprocket is connected to the power output shaft of the drive device. Multiple buckets 35 are arranged in parallel along the length of the transmission chain. The drive device and the drive sprocket are mounted on the support frame 30. The mechanism also includes a swing arm 36 and a telescopic cylinder 37. One end of the swing arm 36 is a free end, and the other end of the swing arm 36 is hinged to the support frame 30 through a hinge shaft. The driven sprocket 33 is located at the free end of the swing arm, and the drive sprocket is located on the hinge shaft. The two ends of the telescopic cylinder 37 are respectively hinged to the swing arm 36 and the support frame 30.
[0026] The working principle of the yam bean planter of this invention is as follows: Before sowing, the walking mechanism is attached to the back of the tractor, and corn stalks or sawdust are added to the soil and filler mixing mechanism 4. Alternatively, sand can be added directly. Yam beans are added to the sowing mechanism 5. During sowing, the drive device 31 on the ditching mechanism is controlled to work, and the swing arm 36 is controlled to swing downward through the telescopic cylinder 37. As the bucket digs out the soil and transports it upward, the swing arm will gradually enter the soil. The ditching mechanism opens a cultivation ditch 15 cm wide and 0.6-1.0 m deep in the field, and the soil taken out during ditching is transferred to the soil and filler mixing mechanism 4. The soil and filler mixing mechanism 4 mixes the soil taken out during ditching with straw or sawdust and then backfills the cultivation ditch. The sowing mechanism 5 sows the yam beans into the backfilled cultivation ditch.
[0027] As a further improvement to the above technical solution, the soil and filler mixing mechanism 4 includes a mixing box 40 and a discharge pipe 42. The mixing box 40 is equipped with a filler and soil inlet 41, which is located below the drive sprocket 32. When the bucket 35 is driven by the transmission chain 34 to the top of the filler and soil inlet, the soil in the bucket 35 can be poured into the soil inlet. The mixing box 40 is equipped with a mixing chamber 44 and a screw conveyor pump located at the bottom of the mixing chamber. The mixing chamber is equipped with a mixer. The screw conveyor pump includes a motor-driven screw 45 and a cylindrical conveyor pipe 46. The axial directions of the screw 45 and the conveyor pipe are parallel to the length direction of the cultivation trench. Multiple discharge pipes 42 are provided, with their top openings arranged sequentially along the bottom of the conveyor pipe 46, and their bottom openings arranged sequentially along the direction of the cultivated trench. In this embodiment, as... Figure 2 As shown, during operation, the transmission chain 34 in the figure is clockwise, so the mixing box 40 is located in front of and below the trenching mechanism 3. Since the discharge pipe 42 is located behind the trenching mechanism 3, the conveying pipe 43 has a relatively long length, thereby connecting the bottom of the mixing box 40 with the top openings of multiple discharge pipes 42.
[0028] As a further improvement to the above technical solution, such as Figure 2 and 3 As shown, it also includes a filler crushing mechanism 6, located above the soil and filler mixing mechanism. The filler crushing mechanism includes a straw crushing chamber 60, with a straw inlet 61 at the top and a straw discharge pipe 62 at the bottom. The straw discharge pipe is connected to the filler and soil inlets on the mixing box. During operation, the filler crushing mechanism 6 can simultaneously crush straw and replenish filler for the soil and filler mixing mechanism.
[0029] As a further improvement to the above technical solution, the sowing mechanism 5 includes a seed box 50 and a yam seed conveying mechanism. The lower part of the seed box is funnel-shaped and has a vertically arranged vertical sidewall. The yam seed conveying mechanism includes a conveyor belt 51 and a drive mechanism for driving the conveyor belt. The drive mechanism includes a drive motor 52, a drive pulley 53, and a driven pulley 54. The drive pulley is connected to the power output shaft of the drive motor. Multiple seed holders 55 are arranged in parallel along the length of the conveyor belt. The bottom of the seed box 50 is provided with a channel that allows the conveyor belt and seed holders to pass through. The drive pulley and the driven pulley are respectively arranged above and below the vertical sidewall. The conveyor belt is sleeved on the drive pulley and the driven pulley. The conveyor belt surrounds the vertical sidewall inside the conveyor belt. One end of the conveyor belt passes through the channel and extends upward along the inner side of the vertical sidewall to the drive pulley.
[0030] As a further improvement to the above technical solution, the sowing mechanism 5 also includes a baffle 56 and a guide trough 57 for guiding the seeds to the ground. The baffle is located outside the seed box and on both sides of the conveyor belt. The bottom of the guide trough is located behind the discharge pipe. The two side walls of the top of the guide trough are connected to the baffles on both sides of the conveyor belt. Soil covering plates 7 are provided on the left and right sides behind the bottom of the guide trough. The soil falling on both sides of the cultivation ditch during ditching is pushed into the cultivation ditch to cover the yam beans through the soil covering plates 7.
[0031] As a further improvement to the above technical solution, a fertilization device 8 is also included. The fertilization device includes a fertilizer box 80 and a fertilizer discharge pipe 81 set at the bottom of the fertilizer box. The fertilizer discharge pipe is equipped with an electromagnetic valve 82 that can control the amount of fertilizer discharged per unit time. The bottom opening of the fertilizer discharge pipe is connected to the top end of the conveying pipe. The above arrangement ensures that the applied fertilizer can be located in the upper layer of the backfill soil layer, so that the fertilizer can be close to the yam beans after planting.
[0032] As a further improvement to the above technical solution, the walking mechanism is equipped with a speed sensor, and also includes a controller and a power supply. The controller is connected to the speed sensor, screw feed pump, mixer, solenoid valve, and drive motor circuit. During sowing, the speed sensor detects the traveling speed of the walking mechanism, and the controller controls the sowing and fertilization speed based on the traveling speed. By setting up the controller and speed sensor, the amount of fertilizer and sowing can be automatically adjusted according to the traveling speed during sowing, thus achieving more precise control of the plant spacing.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
