Description

Technical Field

[0001] This utility model belongs to the field of potato cultivation technology, specifically relating to a potato cultivation machine. Background Technology

[0002] Potato cultivation encompasses soil treatment, seedling transplanting, water and fertilizer management, and pest and disease control. Among these, stratified fertilization based on plant nutrient requirements, soil moisture, and climate characteristics, along with scientifically proportioned and controlled fertilization sites, can achieve a balanced nutrient supply, significantly increasing yield while improving tuber quality.

[0003] Chinese patent document CN222814864U discloses a quantitative fertilization device for potato cultivation. By adding a fertilization depth limiting device, which is fixed to the metal material cylinder by a metal fixing sleeve, to the outside of the quantitative fertilization cylinder and the metal material cylinder, the operator can use the depth limiting plate that is blocked from entering the soil to adjust the depth of the fertilization cylinder into the soil, thereby achieving precise control of quantitative fertilization and fertilizer placement position.

[0004] However, in the existing technology, the fertilization device relies on manual carrying, and repeated lifting and pressing operations are required during use, which is labor-intensive. In addition, the depth limiting plate is prone to sinking into the soil when pressing, resulting in unstable fertilization depth. Therefore, a potato cultivation machine is proposed.

[0018] The beneficial effects of this utility model are as follows: Based on the fact that the moving component can be moved easily and the transmission component can drive the fertilizer application component to operate due to the movement of the moving component, by setting an application component below the pressing valve that can swing together with it and periodically insert into the soil to a set depth, when the insert is inserted to the deepest point, the press valve is pressed to open its internal channel and the flip cover is pulled to open the lower end of the insert when the insert is blocked from entering the soil. This allows the fertilizer supplied by the feeding component to the guiding component to be applied to the specified depth of the soil through the insert, ensuring precise fertilization.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1-5 As shown, a potato cultivation machine includes a moving component 1 that can move the fertilizer to be applied conveniently in the planting area. Below the moving component 1 is a fertilizer application component 2 that can apply fertilizer to a specified depth in the soil at a fixed frequency. On one side of the fertilizer application component 2 is a transmission component 3 that can make it rotate due to the movement of the moving component 1.

[0031] In this embodiment: the mobile component 1 includes a frame 101, a housing 102 is fixedly installed inside the frame 101, a support leg 103 is movably connected to one side of the frame 101, an adjusting rod 104 is provided between the frame 101 and the support leg 103, a first roller 105 is fixedly installed on the lower side of the frame 101 away from the support leg 103, and a second roller 106 is fixedly installed on the lower side of the support leg 103;

[0032] The frame 101 is rotatably connected to the support leg 103. Both the frame 101 and the support leg 103 are rotatably connected to the adjusting rod 104. The adjusting rod 104 consists of an internal threaded cylinder that is rotatably connected to the frame 101 and the support leg 103 respectively, and an external threaded lever that is threaded between two adjacent internal threaded cylinders.

[0033] The crop grower is supported by a frame 101 and outriggers 103. The first roller 105 and the second roller 106 replace the frame 101 and outriggers 103 in contact with the ground, making the crop grower easy to move when subjected to external forces. The fertilizer to be applied is held in a box 102 installed in the frame 101. The length of the adjusting rod 104, which is composed of an external threaded lever and two internal threaded cylinders, can be changed when the external threaded lever rotates relative to the internal threaded cylinders, thereby changing the angle of the outriggers 103 relative to the frame 101.

[0034] In this embodiment: the fertilizer application component 2 includes a guide component that can swing up and down under the action of the transmission component 3, a feeding component that can feed fertilizer placed in the box 102 into the guide component in batches, and an application component that can apply fertilizer after being inserted into the soil to a specified depth.

[0035] The material guiding component includes a press valve 207 located below the housing 102. The feeding component includes an insert 210 fixedly connected below the press valve 207. A flip cover 211 is movably connected to the lower end of the insert 210. A ring frame 212 is fixedly connected to the outer side of the insert 210. A lever 213 is movably connected to one side of the ring frame 212. A pull rope 214 is fixedly connected between the flip cover 211 and the lever 213. The feeding component includes a material guide bin 201 fixedly connected below the housing 102. A bin cover 202 is fixedly connected to both the front and rear of the material guide bin 201. The bin covers 202 are movably connected to each other. A feeding shaft 203 is connected to the outer side of the feeding shaft 203, and a feeding rack 204 located in the guide bin 201 is fixedly connected to the outer side of the feeding shaft 203. The guide component also includes a telescopic cylinder 205 fixedly connected to the bottom of the guide bin 201. A lifting cylinder 206 is fixedly connected to the bottom of the telescopic cylinder 205. A pressing valve 207 is fixedly connected to the bottom of the lifting cylinder 206. Flange end caps are fixedly connected to the lower end of the guide bin 201, the upper and lower ends of the telescopic cylinder 205 and the lifting cylinder 206, and the upper end of the pressing valve 207. A vertical rod 208 is provided between the flange end caps. A nut 209 is provided at the upper end of the vertical rod 208.

[0036] The inner cavity of the feed hopper 201 has a circular inner circumferential surface, and the outer side of the feed rack 204 has a circular outer circumferential surface. The radii of the circular inner circumferential surface and the circular outer circumferential surface are the same. The hopper cover 202 is rotatably connected to the feed shaft 203. The flange end caps connected to the lower end of the telescopic cylinder 205, the lifting cylinder 206, and the pressing valve 207 are all slidably connected to the upright 208. The upright 208 is connected to the nut 209 by a thread. The insert 210 and the flip cover 211, as well as the ring frame 212 and the lever frame 213 are all rotatably connected by a rotating shaft. A torsion spring is provided on the rotating shaft. The lever frame 213 is located near the pressing end of the pressing valve 207.

[0037] Fertilizer flowing from the housing 102 is received by the feed hopper 201. The feed shaft 203, installed inside the feed hopper 201 via the cover 202, rotates and drives the feed frame 204 to rotate within the feed hopper 201. The feed frame 204 contacts the circular inner circumferential surface of the feed hopper 201, dividing this section of the feed hopper 201 into multiple non-interconnected, variable-position, and fixed-volume fertilizer storage areas. A controllable channel for conveying fertilizer to the insert cylinder 210 is formed by the telescopic cylinder 205, lifting cylinder 206, and press valve 207. The nut 209 ensures the fixation of the upright 208 between the flange end cap at the lower end of the feed hopper 201 and the upper end of the telescopic cylinder 205, allowing the upright 208 to stably support the telescopic cylinder 205. 5. The lifting cylinder 206 and the pressing valve 207 provide guidance. The telescopic cylinder 205 can ensure the smooth flow of material between the guide bin 201 and the lifting cylinder 206 when the lifting cylinder 206 moves relative to the upright 208. The fertilizer that enters through the pressing valve 207 is introduced into the soil through the insert 210 after it is inserted into the soil and the lower end is opened. The opening and closing of the lower end of the insert 210 is controlled by the flip cover 211. The lever 213 is installed near the pressing end of the pressing valve 207 by the ring frame 212. The flip cover 211 and the lever 213 are connected by the pull rope 214. The torsion springs set on different rotating shafts can make the flip cover 211 automatically close the lower end of the insert 210 and make the lever 213 move away from the pressing end of the pressing valve 207, respectively.

[0038] In this embodiment: the transmission assembly 3 includes a first rotating group 301 fixedly installed on the lower side of the housing 102, and a second rotating group 302 is provided on the side of the first rotating group 301 near the guide hopper 201. The first rotating group 301 and the second rotating group 302 are both composed of two bearing seats with the same lateral position and a transmission shaft rotatably connected between the two bearing seats with the same lateral position. A first pulley group 303 is provided between the rollers of the two first rollers 105 and the transmission shaft of the first rotating group 301. A second pulley group 304 is provided between the transmission shaft of the first rotating group 301 and the transmission shaft of the second rotating group 302. A third pulley group 305 is provided between the transmission shaft of the second rotating group 302 and the feeding shaft 203. Cams 306 are fixedly connected to the front and rear ends of the transmission shaft of the second rotating group 302. A connecting rod 307 is movably installed between the lifting cylinder 206 and the cam 306.

[0039] The first pulley group 303 consists of pulleys respectively connected to the first roller 105 and the first rotating group 301 transmission shaft, and a belt between two pulleys in the same longitudinal position. The second pulley group 304 and the third pulley group 305 are also arranged in this way. The lifting cylinder 206 and the cam 306 are rotatably connected to the connecting rod 307.

[0040] The rotation of the first roller 105 is transmitted to the second rotating group 302 through the first pulley group 303, the first rotating group 301, and the second pulley group 304. The rotation of the drive shaft of the second rotating group 302 is transmitted to the feeding shaft 203 through the third pulley group 305, so that the feeding shaft 203 drives the feeding frame 204 to rotate in the guide bin 201. The rotation of the drive shaft of the second rotating group 302 is transmitted to the lifting cylinder 206 through the cam 306 and the connecting rod 307, so as to drive the lifting cylinder 206, whose movable range is limited by the upright 208, to swing along the length of the upright 208.

[0041] Working principle: When this cultivation machine is installed for potato cultivation, it is necessary to select the first pulley group 303, the second pulley group 304, and the third pulley group 305 with appropriate transmission ratios according to the required fertilization spacing and depth. This selection is based on the fact that when the first roller 105 travels at a single required fertilization spacing, the feeding frame 204 rotates due to the first roller 105 and the transmission component 3, and the lifting cylinder 206 swings up and down, etc., which can complete one feeding and one up and down swing respectively. Next, the length of the adjusting rod 104 is adjusted. This adjustment aims to adjust the distance of the insert 210 from the ground by changing the inclination of the frame 101 and other components, thereby changing its soil penetration depth.

[0042] After the above adjustments are completed, the frame 101 can be connected to the agricultural machinery with the pulling function, or the staff can push the planter and, after the box 102 contains sufficient fertilizer, the planter can move at a constant speed in the potato planting area to complete the fertilization operation.

[0043] Specifically, when the feeding rack 204 rotates, the fertilizer falling from the box 102 that it receives will fill the fertilizer temporary storage area between it and the inner circular surface of the guide bin 201. The fertilizer that falls into this area will move towards the telescopic cylinder 205 as the feeding rack 204 rotates, and will fall into the telescopic cylinder 205 and enter the lifting cylinder 206 because it is no longer blocked by the guide bin 201. When the lifting cylinder 206 swings, it will drive the pressing valve 207 and the insert cylinder 210 and other components to swing along the length of the upright 208. The lower-positioned insert cylinder 210 will repeatedly insert into the soil during the swing. When the insert cylinder 210 falls to the lowest position, the lever 213, which is set outside the main body of the insert cylinder 210, will be blocked by the soil after contacting the soil and flip towards the pressing valve 207 to press the pressing end of the pressing valve 207 to open its internal channel. The pull rope 214 pulls the flip cover 211 to open the opening at the lower end of the insert cylinder 210, so that the fertilizer in the lifting cylinder 206 can fall into the insert cylinder 210 through the pressing valve 207, and then enter the soil at the lower opening of the insert cylinder 210 to complete the fertilization.

[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
