Description

Technology Field

[0001] The present invention relates to a towable garlic planter that is towed by a tractor or the like, which can gently plow the soil with rotary blades to form ridges, form furrows in multiple rows on top of them to sow garlic, and then compact the ridges. Background Technology

[0003] Generally, mechanized garlic planters are classified into towed and self-propelled types. The intended use of these towed and self-propelled planters depends on the scale of the farm and other conditions, and each type has its own advantages and disadvantages.

[0004] Meanwhile, prior art regarding towed garlic planters related to the present invention is disclosed in Patent Documents 1 to 5, etc. However, towed garlic planters according to these prior art generally have a long front-to-rear length (overall length) of the sieve (planter body). Consequently, when planting garlic seeds in fields or paddy fields while towed behind a tractor, the long sieve causes wide areas at the beginning and end of the ridge where garlic cannot be planted, resulting in a reduction in the planting area. Additionally, there is a problem where missing plants frequently occur during the process of scooping garlic seeds fed into the hopper into planting cups attached at regular intervals on an endless track chain and dropping them into the chute. Furthermore, after planting the garlic seeds on the ridge, the seeds are not completely covered by soil and remain exposed to the outside, hindering normal growth. Additionally, although the shoulder portion of the ridge is formed at a specific angle by the forming blade, it is not properly compacted, causing this part to easily collapse and resulting in soil loss. Finally, after the planting operation is completed, the garlic seeds remaining in the hopper are... There was a problem that the withdrawal process took a considerable amount of time and was cumbersome. Prior art literature

[0006] Korean Published Patent No. 10-2002-0026395 (April 10, 2002) Korean Registered Patent No. 10-0933133 (December 11, 2009) Korean Registered Patent No. 10-1700430 (January 20, 2017) Korean Registered Patent No. 10-2435100 (August 18, 2022) Korean Registered Patent No. 10-2609561 (November 29, 2023) The problem to be solved

[0007] The present invention was devised to solve the aforementioned problems, and the purpose of the present invention is to provide a towable garlic planter with an improved structure that, first, can maximize the planting area in the field by manufacturing a structure that is as compact as possible despite being a towable type; second, can minimize missing plants when the garlic seeds fed into the hopper are scooped up by the garlic conveying device and dropped into the chute; third, can prevent damage to the ridges even if it rains after planting by pressing down and compacting the shoulder portion so that the shoulder portion of the ridge can be pressed down to ensure smooth covering of the garlic seeds after planting and prevent the ridge portion from collapsing; and fourth, can easily extract the garlic seeds remaining in the hopper to the outside after the planting operation is completed. means of solving the problem

[0009] To achieve the above-mentioned objective, the present invention comprises a towable garlic planter having a rotary blade at the front lower part of the body to be towed by a tractor or the like, which rotates by the power of the tractor to plow the soil and form ridges; a planting unit at the rear of the rotary blade to form furrows on the ridges and drop garlic seeds contained in a hopper into the furrows; and a ridge forming unit at the rear of the planting unit to press and compact the sides and top of the ridges where the garlic seeds have been planted.

[0010] A towable garlic planter is provided, wherein a rear wheel that travels along a furrow is provided at the rear of the body, a garlic conveying device that receives rotational force from the rear wheel and adjusts the front-to-rear planting interval of garlic through a transmission is provided at the planting unit, and a discharge port for extracting garlic seeds remaining in the hopper after the planting operation is completed is provided at the front of the hopper.

[0011] The present invention also allows the garlic conveying device to rise vertically from the inner front of the hopper and descend vertically from the outer front of the hopper to feed the garlic seeds from the hopper into the chute, thereby minimizing the loss of garlic seeds and making the front-to-back length of the garlic planter more compact.

[0012] In another embodiment of the present invention, the hopper is equipped with a oscillating cam to relieve the bottleneck of the garlic seeds filled inside, and the oscillating cam is operated in conjunction with the drive of the garlic conveying device, and the rear surface of the hopper forms an inclined surface toward the front lower side, while the lower portion has an inclined surface steeper than the inclined surface.

[0013] The present invention further comprises an auxiliary compaction blade for pressing the shoulder portion of the ridge again in the ridge forming portion, thereby preventing the shoulder portion of the ridge from easily collapsing and soil from being lost. Effects of the invention

[0015] According to the embodiment of the present invention described above, although it is a towable type, the distance from the rotary blade at the front to the furrow forming section at the rear is minimized, thereby maximizing the sowing space in the field. Additionally, due to the cross-sectional shape of the hopper and the oscillating cam, the garlic conveying device can scoop up garlic seeds and drop them into the chute, thereby minimizing missing plants. Furthermore, after sowing the garlic seeds, soil covering and furrow forming are performed, and the shoulder portion of the furrow can be pressed and compacted to prevent the shoulder portion of the furrow from collapsing, thus preventing damage to the furrow. Additionally, there is convenience in that the garlic seeds remaining in the hopper can be easily removed to the outside through the discharge port and tray after the sowing operation is completed.

Specific details for implementing the invention

[0018] Hereinafter, preferred embodiments of the present invention that do not limit the invention will be described in detail with reference to the attached drawings.

[0019] Figures 1 to 4 show actual photographs of a garlic planter according to one embodiment of the present invention.

[0020] As can be seen from the attached photograph of the actual product, the towable garlic planter (1) according to the present embodiment is towed by a tractor (not shown in the illustration) and rotates by the power of the tractor to plow the soil and form a ridge, and a rotary blade (20; tilling blade) is provided at the front lower part of the body (10), and a planting section (40) is provided behind the rotary blade (20) to form a furrow on the ridge and drop garlic seeds contained in a hopper (30) into the furrow, and a furrow forming section (50) is formed behind the planting section (40) to press and compact the side and top of the ridge where the garlic seeds are planted;

[0021] At the rear of the body (10), a rear wheel (60) that travels along a furrow is provided, and at the planting unit (40), a garlic conveying device (70) that receives the rotational force of the rear wheel (60) via a power transmission chain (62) and adjusts the front and rear planting interval of garlic through a transmission (64) is provided, and at the front of the hopper (30), an outlet (32) for extracting garlic seeds remaining in the hopper (30) after the planting operation is completed is provided.

[0023] In this embodiment, as can be seen in the actual photograph of FIG. 4, the discharge port (32) is structured to be openable in an up-and-down sliding shutter manner on the lower front side of the hopper (30), and the discharge port (32) is divided into three sections across the entire width of the hopper (30) so that all garlic seeds remaining inside the hopper (30) can be quickly and conveniently removed to the outside after the sowing operation is completed.

[0025] Reference numeral 34 in the drawing is a tray provided on the outer lower side of the discharge port (32), and when the discharge port (32) is opened, the garlic seeds remaining in the hopper (30) can be poured out into the tray (34) by gravity, so there is an advantage of being able to omit the cumbersome and time-consuming task of manually removing the garlic seeds remaining in the hopper (30) from the top of the hopper after the garlic planting work is completed.

[0026] The above tray (34) is attached to the upper side of the body (10), and when a separate detachable auxiliary tray is placed on the tray (10) to extract garlic seeds, the extracted garlic seeds can be transferred more conveniently into a bag or other container box.

[0028] In addition, in the drawing, reference numeral 12 is a three-point traction unit attached to the front of the body (10), reference numeral 14 is a power transmission shaft for generating driving force on the rotary blade (20) and is connected to the PTO of the tractor, and reference numeral 16 is a drive shaft connected perpendicularly to the power transmission shaft (14), and the rotary blade (20) and the pump (110) of the liquid spraying unit (100) described later are connected to the drive shaft (16) to drive it.

[0030] Meanwhile, reference numeral 80 is a plow blade installed on both front sides of the body (10) to gather soil inward in order to form a ridge, and reference numeral 90 is an adjustable auxiliary wheel installed on the outer side of the sowing section (40).

[0031] Additionally, the symbol 100 is a chemical spraying unit for spraying water or chemicals (herbicides), and a pump (110) is axially coupled to one side of the drive shaft (16). It is connected by a hose to a chemical tank mounted on the tractor side (not shown) and is configured to spray water or herbicides onto the ridge where garlic seeds are sown through a spray nozzle (120) installed at the rear of the sowing unit (40).

[0033] In the towed garlic planter (1) according to the present embodiment, the length from the towing part (12) at the front of the body (10) and the plow blade (90) at the bottom to the rear wheel (60) at the rear is minimized, so the overall length (overall length) is short even when towed by a tractor, so the unplantable area at the beginning and end of the ridge can be minimized.

[0035] FIGS. 5 to 10 illustrate the general structure of a towed garlic planter (1) according to the second embodiment of the present invention. The towed garlic planter according to the present embodiment is basically the same as the garlic planter of the first embodiment described above, except that there are differences in the cross-sectional structure of the hopper (30) and the oscillating cam (130) provided to prevent a bottleneck from occurring in the garlic seeds inside the hopper (30), and the structure of the discharge port (32) due to the change in the cross-sectional shape of the hopper.

[0037] First, in this embodiment as well, although not shown in detail in the actual photograph of the first embodiment described above, the garlic conveying device (70) for supplying garlic seeds contained in the hopper (30) to the sowing section (40), similar to the first embodiment, is configured to rise vertically from the inner rear of the hopper (30) and descend vertically from the outer side of the hopper (30) so that the garlic seeds of the hopper (30) can be directly fed into the chute (42) forming the sowing section (40).

[0038] In this way, as the garlic conveyor (70) rises vertically inside the hopper (30), the planting cups (74) attached at regular intervals to the chain (72) are configured to scoop up garlic seeds. This not only resolves the problem where garlic seeds easily fall out of the planting cups due to vibrations during operation when the garlic conveyor rises inside the hopper with a certain incline rather than vertical as in the conventional method, but also has the advantage of contributing to the design of minimizing the front-to-back length, i.e., the overall length, of the garlic planter.

[0040] In addition, in this embodiment, the front (31) of the hopper (30) is inclined at a predetermined angle toward the rear lower side, and the lower part of the front (31) is formed to have a slope (31a) steeper than the angle of inclination of the front (31). When the garlic seed car is filled inside the hopper (30), the compressive load is applied from the upper front (31) downwards, causing a bottleneck phenomenon to occur at the lower part of the hopper (30) due to the excessive compressive load. Consequently, even though the garlic conveyor (70) is raised, a phenomenon may occur where the garlic seeds cannot climb onto the planting cup (74) of the garlic conveyor (70). However, in the space inside the lower slope (31a), the aforementioned excessive compressive load is somewhat alleviated, thereby resolving the bottleneck phenomenon in the lower space of the hopper (30) and additionally resolving the phenomenon where the garlic seeds cannot climb onto the planting cup (74) of the garlic conveyor (70), i.e., the missing plant phenomenon. There are advantages.

[0042] In this embodiment, a triangular guide bracket (36) is installed on the inner lower part of the hopper (30) to guide the garlic seeds contained inside the hopper (30) toward the garlic conveyor (70) of each row, as shown in FIG. 9.

[0044] In addition, in this embodiment, the hopper (30) is further provided with a oscillating cam (130) on the lower side of the front (31) to further resolve the bottleneck phenomenon of the garlic seeds filled inside, and the oscillating cam (130) is driven in conjunction with the operation of the garlic conveying device (70) by means of a crank shaft (132) and a connecting rod (134), that is, the crank shaft (132) is axially coupled to a driving sprocket (76) located on the upper side of the endless track chain (72) of the garlic conveying device (70) so as to be operated, thereby providing fluidity to the garlic seeds receiving a compressive load inside the hopper (30) so as to resolve the bottleneck phenomenon.

[0045] As can be seen in FIGS. 9 and 10, a plurality of oscillating cams (130) are attached to an oscillating shaft (131) to correspond to a plurality of garlic conveying devices (70) arranged parallel to each other, and each is located at the rear of the garlic conveying device (70).

[0047] In addition, in this embodiment, the ridge forming part (50) basically includes an upper blade (52) and a side blade (54) as in the first embodiment described above, and further includes an auxiliary compaction blade (56) attached to the left and right sides of the upper blade (52) to press down the shoulder part of the ridge. As shown in FIG. 6, the auxiliary compaction blade (56) formed in a delta shape (triangle) is attached to the left and right sides of the upper blade (52) to form the upper surface of the ridge by compacting it, thereby further pressing down the shoulder part (S) of the ridge (B) as shown in FIG. 7, so as to prevent the shoulder part (S) from collapsing.

[0048] In the drawing, symbol 53 is a finishing blade made of soft rubber or the like attached to the rear end of the upper blade (52), and this finishing blade (53) finally covers the furrow formed on the ridge with soil, thereby preventing the garlic seeds sown inside the furrow from being exposed to the outside.

[0050] Meanwhile, the upper blade (52) of the furrow forming part (50) is configured to allow the degree of downward pressing to be adjusted by an angle adjustment device (58).

[0052] In addition, in this embodiment, the discharge port (32) is formed with a steeper slope (31a) than the front (31) at the lower end of the front (31) of the hopper (30), so as can be seen in FIG. 8 and FIG. 10, the discharge port (32) can be opened by connecting it to the lower slope (31a) with a bolt (33) and disassembling it, which is different from the vertical slide opening / closing method applied in the first embodiment described above.

[0054] Although not illustrated in the drawings, it is obvious that a covering device for covering with a mulching film can be installed and operated on the garlic planter of the present invention.

[0056] As explained above, according to the embodiments of the present invention described above, the garlic planter has the advantage of being able to maximize the planting space in the field by having a short overall length, minimizing missing plants during the garlic conveying process by the cross-sectional shape of the hopper and the oscillating cam, effectively covering the garlic seeds with soil by pressing and compacting the shoulder portion with an auxiliary compacting blade after planting, and easily extracting the garlic seeds remaining in the hopper after planting through the discharge port and tray.
