Description

[0001] This application is a divisional application of application number 202210870600.8, filed on July 22, 2022, entitled "A Garlic Planter". Technical Field

[0002] This invention relates to the field of garlic planting machinery technology. Background Technology

[0003] Our company filed a patent application in 2010 entitled "A Garlic Planter," Chinese Patent Publication No. CN111630987A, published on September 8, 2020. This product received a positive market response. However, after long-term in-depth research, our R&D team has identified areas for further improvement in this technical solution:

[0004] The product has the following structure: In order to prevent the garlic seed from rebounding and jumping due to the large distance between the garlic seed outlet and the bottom of the furrow, the garlic seed outlet is located in the gap between the left wing and the right wing of the furrow opener.

[0005] The following problems exist: Due to the limitations of the shape and structure of the composite seed spoon, its width cannot be reduced arbitrarily, thus limiting the width of the garlic seed outlet. At the same time, it limits the minimum width between the left and right wings, preventing the angle between the left and right wings from being further reduced. This results in greater resistance to trenching and is not conducive to energy conservation. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a furrow opener for a garlic planter, which has the characteristics of compact structure, low energy consumption and accurate planting position.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A furrow opener for a garlic planter includes a left wing, a right wing, and a seed furrow retainer. The seed furrow retainer is positioned at the rear end of the garlic seed discharge port, and its front end is embedded in the gap between the left and right wing of the furrow opener.

[0009] The furrow opener is equipped with a transition belt conveyor mechanism, which includes a garlic seed conveyor belt, an upper pulley and a lower pulley. The garlic seed conveyor belt includes a conveyor belt and garlic receiving bodies spaced apart on the conveyor belt. The conveyor belt is supported on the upper pulley and the lower pulley. The transition belt conveyor mechanism is equipped with a conveyor mechanism drive component for connecting with the sprocket drive of the garlic seed metering device to drive the garlic seed conveyor belt to rotate.

[0010] When the garlic planter is planting, a garlic seed falling from the seed discharge port is caught by the garlic receiving body. Under the operation of the garlic seed conveyor belt, the garlic receiving body transports the garlic seed downward. When it is close to the bottom of the furrow opened by the furrow opener, the garlic receiving body flips over, and the garlic seed falls from the garlic receiving body to the bottom of the furrow in front of the seed furrow retainer.

[0011] The invention is further improved in that:

[0012] The conveyor belt is a leather belt, and the garlic receiving body is a leather support plate set perpendicular to the surface of the leather belt. The leather belt and the leather support plate are integrally formed.

[0013] The leather tray is wide enough to accommodate one garlic clove, minimizing the width of the transition belt conveyor mechanism and thus minimizing the angle between the left and right wings. The left and right wings of the furrow opener located on both sides of the leather tray block the garlic clove to prevent it from falling off the sides of the leather tray.

[0014] The driving component of the conveying mechanism is an upper pulley drive sprocket mounted on the pulley of the conveyor belt.

[0015] The beneficial effects of adopting the above technical solution are as follows:

[0016] The garlic seed outlet is located above the furrow opener. The furrow opener is equipped with a transition belt conveyor mechanism, which is used to receive garlic seeds falling from the garlic seed outlet and transport them to the bottom of the furrow opened by the furrow opener in front of the seed furrow holder. This prevents the garlic seeds from bouncing and jumping over due to the large distance between the garlic seed outlet and the bottom of the furrow, thus ensuring the accuracy of the garlic seed planting position. The width of the transition belt conveyor mechanism is designed to be smaller than the width of the garlic seed outlet, thereby avoiding the limitation on the minimum included angle between the left and right wings of the furrow opener, which is located in the gap between the left and right wings of the furrow opener. This further reduces the included angle, thereby further reducing furrowing resistance and saving energy.

[0017] It features a compact structure, low energy consumption, and accurate planting location. Attached Figure Description

[0026] The orientation description in this application is based on the orientation of the garlic planter, with the direction in which the garlic planter moves forward being the front, and the left and right sides being determined by this orientation. Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] For ease of explanation, a garlic planter will be used as an example for detailed description.

[0029] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0030] Depend on Figures 1-7As shown in the embodiment, this embodiment includes a frame 1, on which a garlic planting device is provided; the garlic planting device includes one or more garlic planting mechanisms and a garlic seed metering box (5); the garlic planting mechanism includes a planting mechanism frame 2, a garlic seed metering device and a furrow opener 11 set on the planting mechanism frame 2; the garlic seed metering device includes a garlic conveying chain support structure, a garlic conveying chain and a garlic seed drop protection cover 6; the garlic conveying chain support structure includes a set of sprockets rotatably connected to the planting mechanism frame 2; the garlic conveying chain includes a chain 3 and a composite seed spoon 4, the composite seed spoon 4 being fixed at intervals on the chain 3; the chain 3 is meshed with and supported by each sprocket to form a ring-shaped garlic conveying chain transmission connection structure with a garlic seed conveying and planting channel, the garlic seed conveying and planting channel is arranged from front to back in the forward direction of the chain 3 as follows: first, the garlic seed picking section is conveyed from bottom to top, the upper end of the garlic seed picking section is conveyed to the rear sprocket 7. The garlic seed conveyor enters the rear-to-front section via a forward folding mechanism. The front end of this section then folds downwards via a front sprocket 8 into the top-to-bottom section for planting garlic seeds. The lower end of the planting section folds via a lower front sprocket 9, and a protective cover 6 prevents the garlic seeds from falling out. This covers the planting section, confining the seeds within the protective cover 6 and preventing them from slipping through the gap between the inner wall of the protective cover 6 and the composite seed spoon 4. A corresponding protective cover is also present at the lower end of the planting section. The lower end of the garlic seed drop cover 6 is the garlic seed discharge port 10. Each garlic planting mechanism is arranged horizontally at intervals and is equipped with a garlic seed metering linkage structure for transmission connection with the drive device. The furrow opener 11 includes a left wing 11-1 and a right wing 11-2, and also includes a seed furrow retainer 12. The seed furrow retainer 12 is located at the rear end of the garlic seed discharge port 10, and its front end is embedded in the gap between the left wing 11-1 and the right wing 11-2 of the furrow opener.

[0031] The composite seed spoon 4 includes a seed selection spoon 4-2 and a garlic receiving guide plate 4-1. The cavity of the seed selection spoon 4-2 can hold one garlic seed. In the garlic seed picking section, the opening of the seed selection spoon 4-2 faces rearward. The garlic receiving guide plate 4-1 is located below and behind the seed selection spoon 4-2, and its upper surface is the garlic seed receiving surface. The garlic seed receiving surface smoothly transitions to the lower inner wall of the cavity of the seed selection spoon 4-2, and the garlic seed receiving surface slopes downward from the rear end to the front end to form a garlic seed introduction channel to guide the garlic seed into the cavity of the seed selection spoon 4-2. The garlic planting device is equipped with a seed picking structure, which is located at the fitting part of the garlic seed picking section and the garlic seed metering box 5. The seed picking structure includes a seed picking cavity 20 and a garlic seed picking section that cooperates with the seed picking cavity 20. The gap between the inner wall of the seed picking cavity 20 and the composite seed spoon 4 should not allow the garlic seed to slip. The upper port of the seed-taking chamber is connected to the bottom of the garlic seed metering box 5. When the garlic planter is planting, the drive device drives the garlic conveying chain of each garlic seed metering device to rotate through the linkage structure of the garlic seed metering device. The chain 3 drives the composite seed spoon 4 to be conveyed from the lower port of the seed-taking chamber to the upper port of the seed-taking chamber. After the composite seed spoon 4 in the seed-taking chamber 20 rises out of the upper port of the seed-taking chamber, the garlic seeds in the box of the garlic seed metering box 5 fall from the upper port of the seed-taking chamber into the seed-taking chamber 20. Before the garlic seeds fall to the lower port of the seed-taking chamber, they are blocked by the next composite seed spoon 4 that has entered the seed-taking chamber 20. The garlic seeds received by the garlic receiving guide plate 4-1 are introduced into the cavity of the seed selection spoon 4-2 through the garlic seed introduction channel, so that the seed selection spoon 4-2 completes the action of selecting a garlic seed in the seed-taking structure.

[0032] The composite seed scoop 4, which selects a single garlic seed, rises from the seed-taking chamber 20 into the garlic seed-discharging box 5. Then, it is folded forward by the rear sprocket 7 and enters the garlic seed conveying section from back to front. The composite seed scoop 4 is flipped accordingly, and the seed selection scoop 4-2, which has already collected a single garlic seed, faces upward to prevent the garlic seed from falling during the conveying process. The garlic receiving guide plate 4-1 is erected so that the garlic seed on the garlic receiving guide plate 4-1 falls into the garlic seed-discharging box 5. Then, it is folded downward by the front sprocket 8 and enters the garlic seed sowing section from top to bottom. The composite seed scoop 4 is flipped accordingly, and the cavity of the seed selection scoop 4-2 tilts downward from the inside to the outside so that a single garlic seed in the seed selection scoop 4-2 slides out of the seed selection scoop 4-2 and falls downward in the closed channel formed by the inner wall of the anti-garlic seed falling cover 6. It is then received on the back of the composite seed scoop 4 below and discharged from the garlic seed discharging port 10.

[0033] The garlic seed outlet 10 is located above the furrow opener 11. The furrow opener 11 is equipped with a transition belt conveyor mechanism, which includes a garlic seed conveyor belt, an upper pulley 21 and a lower pulley 22. The garlic seed conveyor belt includes a conveyor belt 23 and garlic receiving bodies 24 spaced apart on the conveyor belt 23. The conveyor belt 23 is supported on the upper pulley 21 and the lower pulley 22 for transmission connection. The transition belt conveyor mechanism is connected to the sprocket drive of the garlic seed outlet 10 through a conveyor belt transmission structure to drive the garlic seed conveyor belt. The transition belt conveyor mechanism is used to receive garlic seed seed outlet 10. The fallen garlic seeds are conveyed to the bottom of the furrow opened by the furrow opener 11 in front of the seed furrow retainer 12; this prevents the garlic seeds from bouncing and jumping due to the large distance between the garlic seed outlet 10 and the bottom of the furrow, thus ensuring the accuracy of the garlic seed planting position; the width of the transition belt conveyor mechanism is smaller than the width of the garlic seed outlet 10, thus avoiding the limitation of the minimum included angle between the left wing 11-1 and the right wing 11-2 of the furrow opener because the garlic seed outlet 10 is located in the gap between the left wing 11-1 and the right wing 11-2 of the furrow opener, so as to further reduce the included angle, thereby further reducing the furrow opening resistance and saving energy;

[0034] When the garlic planter is planting, a garlic seed falling from the seed discharge port 10 is caught by the garlic receiving body 24. Under the operation of the garlic seed conveyor belt, the garlic receiving body 24 transports the garlic seed downward. When it is close to the bottom of the furrow opened by the furrow opener 11, the garlic receiving body 24 flips over, and the garlic seed falls from the garlic receiving body 24 to the bottom of the furrow in front of the seed furrow retainer 12.

[0035] The back of the composite seed spoon 4 is a garlic seed tray 4-3 formed by the rear end face of the seed selection spoon 4-2 and the garlic receiving guide plate 4-1, so as to receive the garlic seeds falling from the seed selection spoon 4-2 above within the garlic seed falling protection cover 6.

[0036] The garlic seed drop prevention cover 6 is fixedly connected to the planting mechanism frame 2; in the garlic conveyor chain support structure, there are four sprockets rotatably connected to the planting mechanism frame 2, namely the rear sprocket 7, the front sprocket 8, the lower front sprocket 9, and the lower rear sprocket 13, thus forming an oblique quadrilateral support for the garlic conveyor chain; in order to reduce the height of the annular garlic conveyor chain transmission connection structure, the garlic seed planting section is inclined from top to bottom and backward, thereby reducing the space occupied at the bottom of the garlic planter and making the garlic planter smaller; the garlic seed picking section is inclined from bottom to top and forward, in order to facilitate the design of the garlic seed inlet channel tilt angle in the garlic receiving guide plate 4-1.

[0037] The upper port of the seed-taking chamber is located at the lowest point of the garlic seed-raising box 5. The inner wall of the garlic seed-raising box 5 has a garlic seed guide ramp. The garlic seed guide ramp gradually slopes and converges from top to bottom toward the upper port of the seed-taking chamber, so that the garlic seeds in the garlic seed-raising box 5 slide down the garlic seed guide ramp and are guided into the seed-taking chamber 20. When there are few garlic seeds in the garlic seed-raising box 5, it will not affect the operation of the seed-taking structure.

[0038] The conveyor belt drive structure includes an upper pulley drive sprocket 28 mounted on the upper pulley 21 of the conveyor belt, a garlic seed metering device drive sprocket 29 coaxially fixed with the lower front sprocket 9, and a transition belt conveyor mechanism drive chain 25. The upper pulley drive sprocket 28 and the garlic seed metering device drive sprocket 29 are connected by the transition belt conveyor mechanism drive chain 25.

[0039] The conveyor belt 23 is a leather belt, and the garlic receiving body 24 is a leather support plate set perpendicular to the surface of the leather belt. The leather belt and the leather support plate are integrally formed.

[0040] The leather tray has a width to accommodate one garlic clove, so as to minimize the width of the transition belt conveyor mechanism, thereby minimizing the angle between the left wing 11-1 and the right wing 11-2. The left wing 11-1 and the right wing 11-2 of the furrow opener located on both sides of the leather tray form a barrier to prevent the garlic clove from falling off the sides of the leather tray.

[0041] The garlic seed metering device linkage structure is a shaft-hub connection structure: the inner hole of the lower front sprocket 9 in each garlic seed metering device is fixedly connected to the bushing 14. The inner hole of the bushing 14 is a transmission hole with a polygonal cross-section. The garlic planting mechanism linkage shaft 15 is slidably connected to the transmission hole of each garlic seed metering device. The cross-section of the garlic planting mechanism linkage shaft 15 is a polygon that matches the cross-section of the inner hole of the bushing 14, so as to fix them together circumferentially. The lower front sprocket 9 and the garlic seed metering device transmission sprocket 29 are fixed together coaxially through the garlic planting mechanism linkage shaft 15.

[0042] A drive unit, a wheel drive chain, and a garlic seed metering device transmission structure are provided on the frame 1. The drive unit includes a diesel engine or gasoline engine 16, a main clutch 17, and a transmission 18. The transmission 18 converts the high-speed output of the diesel engine or gasoline engine 16 into a low-speed, high-torque power output through the wheel drive output shaft 26 of the transmission 18. The main clutch 17 connects or disconnects the power transmission between the diesel engine or gasoline engine 16 and the transmission 18. The wheel drive output shaft 26 of the transmission 18 drives the wheels to rotate through the wheel drive chain.

[0043] The garlic seed metering device transmission structure includes a secondary clutch, a seed metering device gearbox (plant spacing adjustment device) 19, and a garlic planting mechanism drive shaft 27. The planter drive power output shaft (not shown in the figure) of the gearbox 18 is speed-changed by the seed metering device gearbox 19 (to adjust the plant spacing), and then connected to the garlic planting mechanism linkage shaft 15 through the garlic planting mechanism drive shaft 27, thereby driving the garlic conveyor chain of each garlic seed metering device to rotate. The secondary clutch connects or disconnects the power output shaft of the main clutch 17 with the power output shaft of the planter drive of the gearbox 18 to transmit power. The secondary clutch is located inside the gearbox 18.
