[0002] Garlic is a condiment in daily life, which has a large demand and the planting area is increasing year by year. Manual planting of garlic is labor-intensive and inefficient, so mechanized planting is an inevitable trend.

[0003] At present, the main reasons for the low efficiency of garlic planters are: (1) Due to the large individual differences of garlic, the time for transporting garlic seeds and adjusting the direction of garlic seeds during planting is inconsistent. In order to ensure the uniform row spacing after planting, the garlic seeds with slow bulb adjustment can only be planted together after adjustment. This causes the planting speed of the planter to be set very slowly, thereby limiting the forward speed of the whole machine; (2) In order to ensure the qualified rate of single seed removal, the seed removal speed of the single seed removal device is low; (3) In order to ensure the upright rate of planting during the planting process, the vertical moving speed of the planting device is low. Restricted by the above problems, the garlic planter in the prior art has a slow moving speed and it is difficult to improve the operating efficiency. Summary of the invention

[0010] The ball head adopts an ellipsoidal structure, and there is a smooth transition between the ball head and the push rod.

[0011] A lifting frame is provided on the front side of the frame, the garlic box fixing box is fixed to the lower part of the lifting frame, and rotating support seats for installing a transmission rod are respectively provided on both sides of the upper part of the lifting frame, and guide rod bases are respectively fixedly connected to the left and right sides of the bottom of the lifting frame, and each guide rod base is respectively equipped with a guide rod arranged vertically upward, and fixed rods extending forward are respectively fixed on the left and right sides of the frame, and each fixed rod is respectively provided with a guide sleeve for the guide rod to pass upward, and the guide sleeve is located above the guide rod base.

[0012] The front plow comprises a comb-toothed plow frame and plows fixed on the plow frame at even intervals on the left and right sides. Each fixing rod is fixedly connected with a vertically arranged connecting rod, and the left and right sides of the plow frame are fixedly connected to the two connecting rods.

[0013] A leveling rake is arranged at the rear end of the frame, and the teeth of the leveling rake are arranged downwards.

[0014] The frame is provided with a chain tensioning mechanism, which includes an arc-shaped adjustment seat and a tensioning sprocket. The tensioning sprocket is used to tension the chain between the driven sprocket and the driving sprocket. The arc-shaped adjustment seat is provided with adjustment holes distributed in an arc shape. A connecting shaft is fixed at the center of the tensioning sprocket, and the connecting shaft is installed in the adjustment hole.

[0015] The beneficial effect of the present invention is that the rotation of the front wheel shaft drives the cam to rotate, thereby driving the push rod to move up and down, that is, the power for the push rod to move up and down is provided by the vehicle driving mechanism, and the push rod reciprocates up and down in the garlic box fixed box under the driving mechanism, continuously pushing out the garlic seeds in the garlic storage magazine. The garlic seed bulbs are arranged in a straight line upward in the garlic storage magazine, and the propulsion spring pushes the sliding baffle to move, thereby pushing the garlic seeds to move along the internal channel of the garlic storage magazine toward the garlic box fixed box and enter the internal cavity of the garlic box fixed box. When the push rod moves downward, the ball head at the lower end of the push rod pushes the garlic seeds to move downward, and at the same time, the garlic-dropping baffle opens and the garlic seeds fall. After the garlic seeds have fallen, the cam rotates and enters the return stroke, and the push rod moves upward under the action of the reset spring. At this time, the garlic outlet of the garlic storage magazine is blocked by the ball head of the push rod, and the garlic seeds cannot enter the inner cavity of the garlic box fixed box. At the same time, the garlic-dropping baffle closes, and when the push rod moves upward to no longer block the garlic outlet of the garlic storage magazine, the next garlic seed is pushed into the inner cavity of the garlic box fixed box, completing one garlic seed sowing. The garlic seeding speed can be controlled by the vehicle drive mechanism speed and the chain drive ratio. The garlic magazine pusher adopts an array arrangement, so that the whole machine can complete the simultaneous planting of multiple rows and columns of garlic at one time, improve work efficiency, improve the consistency of sowing plant spacing, and effectively solve the problem that the seeder walking speed cannot be significantly increased and the consistency of plant spacing is poor due to inconsistent adjustment time of bulbils between different rows.

[0016] Preferably, the garlic storage magazine is installed on the garlic box fixing box, and one end of the garlic storage magazine connected to the garlic box fixing box is designed with a fixing structure that cooperates with the garlic box fixing box to form a plug-in structure, which can realize the rapid installation, insertion, disassembly and replacement of the garlic storage magazine.

[0017] Preferably, when the garlic cover is closed, the garlic seeds cannot fall out from the bottom of the garlic box fixed body (that is, the garlic seeds are guaranteed not to fall out due to vehicle vibration and other reasons), and when the garlic cover is opened, the garlic seeds fall out from the bottom of the garlic box fixed body. The principle of opening and closing the garlic cover is as follows: the pressure sleeve is fixed on the push rod, hits the pressure plate, and forces it to move downward, the connecting rod follows the pressure plate to move downward, and the sliding rod moves obliquely upward in the guide groove, driving the garlic cover to open; the push rod moves upward, the pressure sleeve separates from the large push rod, the spring pushes the pressure plate, the connecting rod follows the pressure plate to move upward, the sliding rod moves obliquely downward in the guide groove, driving the garlic cover to open, the spring is compressed when the pressure plate moves downward, and when the pressure plate is not affected by the pressure sleeve, it pushes the pressure plate upward to move, and the connecting rod follows the pressure plate to move upward, driving the garlic cover to close.

[0018] Preferably, the garlic storage magazine and the garlic magazine fixing box are fixed on a lifting frame, and the lifting frame can be connected to the frame through a slide rail. When sowing, the lifting frame is lowered to make it close to the ground, thereby reducing the landing distance of the garlic seeds and improving the efficiency of germination. When replacing the garlic storage magazine or loading garlic seeds, the lifting frame is raised to facilitate the disassembly and assembly of the garlic storage magazine; the guide rod plays a guiding role in the up and down movement of the lifting frame.

[0019] Preferably, a soil furrowing plow is installed at the front end of the frame and is distributed in a horizontal array with a spacing corresponding to the magazine pushing structure on the lifting frame. When the whole vehicle is moving, the soil is pushed away to form spaced planting troughs to ensure that the garlic seeds can fall into the corresponding soil troughs; at the rear end of the frame, a rake-type structure is installed for leveling the soil and burying the garlic seeds.

[0020] Preferably, when the lifting frame is in the process of rising and falling, the transmission chain is easy to loosen, and the tensioning adjustment structure can be used to adjust the tension of the transmission chain when the lifting frame is located at different positions to ensure the transmission efficiency.

[0029] like Fig.17 As shown, a lifting frame 6 is provided on the front side of the frame 1, the garlic box fixing box 5.2 is fixed to the lower part of the lifting frame 6, and rotating support seats 6.1 for installing the transmission rod 4.1 are respectively provided on both sides of the upper part of the lifting frame 6, and guide rod bases 6.4 are respectively fixedly connected to the left and right sides of the bottom of the lifting frame 6, and each guide rod base is respectively equipped with a guide rod 6.2 arranged vertically upward, and fixed rods 1.1 extending forward are respectively fixed on the left and right sides of the frame 1, and each fixed rod 1.1 is respectively provided with a guide sleeve 6.3 for the guide rod 6.2 to pass upward, and the guide sleeve 6.3 is located above the guide rod base 6.4.

[0030] The front plough 7 comprises a comb-tooth plough frame 7.1 and ploughs 7.2 fixed on the plough frame 7.1 at even intervals on the left and right sides. Each fixed rod 1.1 is fixedly connected to a vertically arranged connecting rod 1.2, and the left and right sides of the plough frame 7.1 are fixedly connected to two connecting rods 1.2. A leveling harrow 8 is arranged at the rear end of the frame 1, and the teeth of the leveling harrow 8 are arranged downward.

[0031] like Fig.18As shown, the frame 1 is provided with a chain tensioning mechanism 9, which includes an arc-shaped adjustment seat 9.1 and a tensioning sprocket 9.2. The tensioning sprocket 9.2 is used to tension the chain between the driven sprocket 4.3 and the driving sprocket 4.2. The arc-shaped adjustment seat 9.1 is provided with adjustment holes distributed in an arc shape. A connecting shaft 9.3 is fixed at the center of the tensioning sprocket 9.2, and the connecting shaft 9.3 is installed in the adjustment hole.

[0032] like Figure 1 As shown, the front plow 7, wheels, and leveling harrow 8 are all fixed on the vehicle frame 1, wherein the plow 7.2 in the front plow 7 is a horizontal array structure, the spacing between adjacent plows 7.2 is the same as the spacing between the sowing mechanism 5, and the front plow 7 is provided with positioning holes, and the height of the plow can be adjusted through the positioning holes at the corresponding positions on the connecting rod 1.2 of the vehicle frame 1. When the whole vehicle is moving, the front plow 1 can push the soil away to form spaced planting grooves. The harrow frame structure 9 is used to flatten the soil and bury the garlic seeds.

[0033] The garlic box 5.2 is fixed on the lifting frame 6. A garlic cover is provided at the bottom of the garlic box 5.2. When the cover is closed, the garlic seeds cannot fall down and can only stay in the internal chamber of the garlic box 5.2. The opening and closing of the cover is determined by the movement of the push rod. The push rod 4.5 reciprocates up and down through the rotation of the cam 4.4. When working, the garlic storage magazine 5.1, the garlic box 5.2 and the push rod 4.5 move in coordination with the installation position, size and coordination. The garlic storage magazine 5.1 is in a round tube structure, and the inner wall diameter of the tube only allows the garlic bulbs to face upward and be arranged in a single row. A vertical second through hole 5.16 is provided at the rear end of the garlic storage magazine 5.1, and the diameter of the second through hole allows a single garlic seed to pass through and leave the garlic storage magazine 5.1. A magazine cover is installed at the front end of the garlic storage magazine 5.1, and a sliding baffle is installed inside. A propulsion spring 5.12 is provided between the magazine cover and the sliding baffle. When a single garlic seed is in the garlic storage magazine 5.1, the propulsion spring 5.12 pushes the sliding baffle 5.11 to move, and the push spring 5.12 pushes the sliding baffle 5.11 to move. The movable garlic seeds move along the internal channel of the garlic storage magazine 5.1 toward the garlic box fixed box 5.2 and enter the internal chamber of the garlic box fixed box 5.2. The push rod 4.5 moves downward, and the ball head 4.9 at the lower end of the push rod pushes the garlic seeds downward. At the same time, the pressing sleeve 4.11 on the push rod 4.5 presses the pressing plate 5.24 to move downward. The relative position of the pressing plate 5.24 and the connecting rod 5.25 is fixed by the clamping block 5.28. The connecting rod 5.25 moves downward, the garlic falling blocking cover 5.23 opens, and the garlic seeds fall. After the garlic seeds are dropped, the cam 4.4 rotates and enters the return stroke, and the push rod 4.5 moves upward under the action of the reset spring 4.8. At this time, the garlic outlet of the garlic storage magazine 5.1 is blocked by the ball head 4.9 of the push rod, and the garlic seeds cannot enter the inner cavity of the garlic box fixed body 5.2. At the same time, since the push rod 4.5 moves upward, the pressure plate 5.24 is no longer under pressure, and it resets upward under the action of the spring between the pressure plate 5.24 and the garlic box fixed body 5.2, driving the connecting rod 5.25 to move upward, and the garlic falling blocking cover 5.23 is closed. When the push rod 4.5 moves upward to no longer block the garlic outlet of the garlic storage magazine 5.1, the next garlic seed is pushed into the inner cavity of the garlic box fixed body 5.2, completing a garlic seed sowing.

[0034] The function of the garlic-falling cover is: when it is closed, the garlic seeds cannot fall out from the bottom of the garlic box fixed body (i.e., it is ensured that the garlic seeds will not fall due to vehicle vibration, etc.); when it is opened, the garlic seeds will fall out from the bottom of the garlic box fixed body. The principle of opening and closing the garlic blocking cover is as follows: the pressing sleeve 4.11 is fixed on the pushing rod 4.5, hits the pressing plate 5.24, and forces it to move downward, the connecting rod 5.25 follows the pressing plate 5.24 to move downward, and the sliding rod 5.27 moves obliquely upward in the guide groove 5.26, driving the garlic blocking cover 5.23 to open; the pushing rod 4.5 moves upward, the pressing sleeve 4.11 is separated from the large pushing rod 4.5, the spring pushes the pressing plate 5.24, the connecting rod 5.25 follows the pressing plate 5.24 to move upward, and the sliding rod 5.27 moves obliquely downward in the guide groove 5.26, driving the garlic blocking cover 5.23 to open, the spring is compressed when the pressing plate 5.24 moves downward, and when the pressing plate 5.24 is not affected by the pressing sleeve 4.11, the pressing plate 5.24 is pushed upward to move, and the connecting rod 5.25 follows the pressing plate 5.24 to move upward, driving the garlic blocking cover 5.23 to close.

[0035] The sowing mechanism adopts a magazine-propelled structure and is distributed in an array, so that multiple rows and columns of garlic can be planted at one time, which can improve work efficiency and consistency of sowing spacing. The end of the garlic storage magazine 5.1 connected to the garlic box 5.2 is designed with a fixed structure that cooperates with the garlic box 5.2 to form a plug-in structure, which can realize the rapid insertion and removal and replacement of the garlic storage magazine 5.1, thereby realizing rapid filling of garlic seeds.

[0036] The garlic box fixing box 5.2 and the push rod 4.5 are fixed on the same lifting frame. The interior of the garlic box fixing box 5.2 is a three-way structure. The diameter of the end structure of the push rod 4.5 matches the diameter of the first through hole 5.21 of the garlic box fixing box 5.2. The push rod 4.5 can move back and forth inside the garlic box fixing box 5.2. The reciprocating stroke and speed of the push rod 4.5 are adjusted by the shape of the cam. The speed of the cam rotation can be adjusted by adjusting the transmission ratio of the chain drive to control the reciprocating speed of the push rod. The push stroke (downward movement) and return stroke (upward movement) of the push rod 4.5 pass through the second through hole of the garlic storage magazine 5.1. The size of the second through hole only allows a single garlic seed to pass through.

[0037] The lifting frame 6 can be connected to the frame 1 through a slide rail, and the transmission rod 4.1 is installed on the frame 1 through a rotating support seat 6.1. Guide rods 6.2 are respectively provided on both sides of the lifting frame 6. When the lifting frame 6 adjusts the height position on the frame 1, the guide rod 6.2 moves up and down in the guide sleeve 6.3, thereby constraining the up and down movement of the lifting frame 6. When the seed drill performs sowing operations, the lifting frame is lowered, and the garlic is dropped close to the ground, which reduces the landing distance of the garlic seeds and improves the efficiency of the positive sprout. When it is necessary to fill the garlic storage magazine 5.2 with garlic seeds, or replace the garlic storage magazine 5.2, the lifting frame is raised for easy operation. The transmission rod 4.1 is rotatably set on the lifting frame 6, and the cam 4.4 is distributed in an array on the transmission rod 4.1. The active sprocket drives the transmission rod 4.1 and the cam 4.4 to rotate, providing power for the up and down movement of the guide rod 6.3. The frame 1 is provided with a sprocket tensioning mechanism 9. When the lifting frame 6 is in the process of ascending and descending, the transmission chain between the driving sprocket and the driven sprocket is easy to loosen. The sprocket tensioning mechanism 9 can be used to adjust the transmission chain to make it tight when the lifting frame 6 is in different positions to ensure the transmission efficiency. The arc-shaped adjustment seat 9.1 is a semicircular structure, and the position of the tensioning sprocket can be adjusted through the adjustment holes at different positions.

[0038] The magazine-propelled garlic seeder of the present invention can simultaneously drop multiple rows of garlic at one time, thereby improving operation efficiency and consistency of sowing spacing.
