Description

Technical Field

[0001] This invention relates to the field of fertilizer application machines, specifically a fertilizer application machine for potatoes grown in strip planting with soybeans during the potato growth period. Background Technology

[0002] In recent years, the potato-soybean strip intercropping model has been widely promoted and applied in my country and even worldwide due to its advantages such as effectively improving land utilization, light energy utilization, increasing yield per unit area and economic benefits, improving soil structure, and reducing the occurrence of pests and diseases. Alternating strip planting is employed. The two crops grow in staggered spaces and may have overlapping or interleaved growth periods. Potatoes are a crop with high fertilizer requirements, especially during tuber formation and expansion stages (usually around budding and flowering), when their demand for nutrients such as potassium and nitrogen reaches its peak. At this time, basal fertilizer alone is insufficient to meet their rapid growth needs. Timely and precise topdressing (especially potassium fertilizer and appropriate amounts of nitrogen fertilizer) is crucial for increasing potato tuber yield and improving quality (such as dry matter content and starch content).

[0003] Current topdressing methods often use a scattered application method, which has low precision and poor fertilizer utilization efficiency. At the same time, the duckbill-style perforation method is prone to clogging, affecting the efficiency of topdressing. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a topdressing machine for potato and soybean strip planting during the potato growth period, comprising a fertilizer box, a topdressing device rotatably connected to the side of the fertilizer box via a bracket, an extraction device rotatably connected to the side of the topdressing device, a fixed end of a spring telescopic rod fixedly connected to the top of the fertilizer box, an equipment bracket fixedly connected to the movable end of the spring telescopic rod, and rollers fixedly connected to the bottom of the equipment bracket; The topdressing device includes a lower base plate with an arc-shaped sliding hole at its top. An upper top plate is rotatably connected to the top of the lower base plate, and a straight sliding hole is provided at its top. A guide component is slidably connected to the inner wall of the straight sliding hole. A topdressing component is fixedly connected to the side of the guide component, and an adjustment component is fixedly connected to the side of the lower base plate. The side of the extraction device communicates with the side of the guide component. The side of the lower base plate is rotatably connected to the side of the fertilizer box via a bracket. The adjustment component can be manually rotated, causing relative movement between the lower base plate and the upper top plate, which in turn moves the guide component. The movement of the guide component moves the topdressing component, thereby changing the spacing between multiple sets of topdressing components to perform topdressing operations at different spacings. The adjustment component's characteristics ensure that it remains in a fixed position after adjustment, facilitating continuous operation. The guide component is used to adjust the position of the topdressing components and intermittently supply water to them, preventing waste of powdered fertilizer when topdressing is not being performed.

[0005] Preferably, the guide assembly includes a sliding base, a limit rod fixedly connected to the center of the bottom of the sliding base, limit sliders fixedly connected to the bottom of the sliding base on both sides of the limit rod, a support plate fixedly connected to one side of the top of the sliding base, a hollow telescopic rod extending through and fixedly connected to the side of the support plate, a fixed end of the hollow telescopic rod communicating with a fixed cylinder, a rotating cylinder rotatably connected to the inner wall of the fixed cylinder, a through hole adapted to the hollow telescopic rod on the side of the rotating cylinder, a bottom of the rotating cylinder communicating with the side of the extraction device, a lower base plate and an upper top plate sleeved on the side of the fixed cylinder and rotatably connected to the fixed cylinder, the sliding base slidingly connected to the top of the upper top plate via the limit sliders, and the support plate being far from the top of the sliding base. One side of the hollow telescopic rod is fixedly connected to the side of the topdressing component. Powdered fertilizer is introduced through a rotating cylinder, which is fixed to the extraction device, allowing the rotating cylinder and the fixed cylinder to rotate relative to each other. This allows the powdered fertilizer to enter the hollow telescopic rod and be discharged when the through hole on the side of the rotating cylinder connects with the fixed end of the hollow telescopic rod. A limiting rod guides the sliding base, guided by the combined action of an arc-shaped sliding hole and a straight sliding hole. This allows the limiting rod to drive the sliding base to slide on the top of the upper plate, and the limiting sliding strip prevents the sliding base from detaching from the surface of the upper plate. The topdressing component is supported by a support plate, facilitating drilling and topdressing.

[0006] Preferably, the topdressing component includes an insulation pipe, a fixing pipe is sleeved and fixedly connected to the side of the insulation pipe, a first sliding groove is opened on the side of the fixing pipe, a driving component is slidably connected to the inner wall of the first sliding groove, an expansion component is fixedly connected to the bottom of the insulation pipe, the driving component is slidably connected to the expansion component through a sliding shaft, the top of the fixing pipe is fixedly connected to the side of the support plate, and the top of the insulation pipe is connected to the movable end of the hollow telescopic rod.

[0007] Preferably, the driving assembly includes a driving slide rod, a contact base is fixedly connected to the bottom of the driving slide rod, a second slide groove is provided on the side of the driving slide rod, a driving rod is fixedly connected to the side of the driving slide rod, a connecting seat is fixedly connected to the top of the driving slide rod, a first spring is fixedly connected to the top of the connecting seat, the end of the first spring away from the connecting seat is fixedly connected to the side of the fixing tube, and a slide bar adapted to the second slide groove is fixedly connected to the side of the fixing tube.

[0008] Preferably, the reaming assembly includes a fixed base, a rotating base rotatably connected to the side of the fixed base via a rotating shaft, a sliding hole on the side of the rotating base, a reaming cone fixedly connected to the bottom of the rotating base, a guide groove on the side of the reaming cone, a fixed base fixedly connected to the bottom of the fixed tube, and a second sliding groove slidably connected to the rotating base via the sliding hole. When the lower base plate rotates as a whole, the upper top plate drives the limiting rod to rotate, the limiting rod rotation drives the support plate to rotate along the rotation center of the lower base plate, the through hole of the rotating cylinder points downward, the support plate drives the insulation tube to move, the insulation tube drives the fixed tube to move, the fixed tube drives the first spring to move, the first spring drives the connecting base to move, the connecting base movement drives the drive slide rod to move, the drive slide rod movement drives the contact base to move, when the contact base moves to contact the ground, the ground's reaction force on the contact base drives the contact base to slide along the side of the fixed tube, thereby driving the drive rod to move, the drive rod movement drives the sliding hole to move, the sliding hole movement drives the rotating base to move, the rotating base movement drives the reaming cone to slide along the side of the fixed base. The rotation causes the expanding cone to unfold. After the expanding cone penetrates the ground to a certain depth, it unfolds further. Under the influence of gravity, the powdered fertilizer enters the interior of the insulation pipe along the inner wall of the hollow telescopic rod and then enters the side of the guide groove, directly reaching the ground for targeted topdressing. During the movement, when the contact base leaves the ground, the elastic force provided by the first spring drives the drive slide rod downwards. The downward movement of the drive slide rod drives the drive rod downwards, which in turn moves the sliding hole, causing the rotating seat to return to its original position. This keeps the expanding cone closed again, and at this time, the through hole of the hollow telescopic rod and the rotating cylinder are misaligned. The powdered fertilizer stops entering the hollow telescopic rod, preventing waste and achieving precise topdressing at designated locations. The second sliding groove restricts the sliding trajectory of the drive slide rod, and the insulation pipe keeps the powdered fertilizer warm, preventing clumping and affecting the topdressing effect. This also avoids the clogging problems caused by traditional duckbill-style perforation designs, facilitating long-term continuous operation.

[0009] Preferably, the adjustment assembly includes a first movable seat, a first connecting plate rotatably connected to the top of the first movable seat via a pivot, a screw rotatably connected to the side of the first movable seat, a second movable seat sleeved and threadedly connected to the side of the screw, a second connecting plate rotatably connected to the top of the second movable seat via a pivot, a handle turntable fixedly connected to the end of the screw away from the second movable seat, a side of the first connecting plate fixedly connected to the side of the lower base plate, and a side of the second connecting plate fixedly connected to the side of the upper top plate.

[0010] Preferably, the extraction device includes an electric air pump. The inlet end of the electric air pump is connected to an inlet pipe. An inlet hole is provided on the side of the inlet pipe. A rotating ring is sleeved and rotatably connected to the side of the inlet pipe at the position of the inlet hole. An agitator blade is fixedly connected to the side of the rotating ring. The outlet end of the electric air pump is connected to an outlet pipe. The end of the outlet pipe away from the electric air pump is connected to a rotating cylinder. The bottom of the electric air pump is slidably connected to the inner wall side of the fertilizer tank.

[0011] This invention provides a potato topdressing machine for potato-soybean strip planting. It has the following beneficial effects: 1. This potato-soybean strip planting potato growth period topdressing machine is equipped with a lower base plate. The adjustment component is manually driven to rotate. The rotation of the adjustment component causes relative movement between the lower base plate and the upper top plate, which in turn moves the guide component. The movement of the guide component moves the topdressing components, thereby changing the spacing between multiple sets of topdressing components, thus performing topdressing operations at different intervals. The characteristics of the adjustment component ensure that it remains in a fixed position after adjustment, which facilitates continuous operation. The guide component is used to adjust the position of the topdressing components and intermittently supply water to the topdressing components, thereby preventing the waste of powdered fertilizer when topdressing is not performed.

[0012] 2. This potato-soybean strip planting topdressing machine is equipped with a rotating drum. Powdered fertilizer is introduced through the rotating drum. The rotating drum and the extraction device are kept fixed, so that the rotating drum and the fixed drum rotate relative to each other. When the through hole on the side of the rotating drum connects with the fixed end of the hollow telescopic rod, the powdered fertilizer enters the interior of the hollow telescopic rod and is then discharged. A limiting rod is used to guide the sliding base. Under the combined action of the arc-shaped sliding hole and the straight sliding hole, the limiting rod drives the sliding base to slide on the top of the upper plate. Under the restriction of the limiting sliding strip, the sliding base is prevented from detaching from the surface of the upper plate. The topdressing component is supported by a support plate, which facilitates drilling and topdressing.

[0013] 3. This potato-soybean strip planting topdressing machine is equipped with a limit rod. When the lower base plate rotates as a whole, the upper top plate drives the limit rod to rotate. The rotation of the limit rod causes the support plate to rotate along the rotation center of the lower base plate. The through hole of the rotating cylinder points downward. The support plate drives the insulation pipe to move, the insulation pipe drives the fixed pipe to move, the fixed pipe drives the first spring to move, the first spring drives the connecting seat to move, the connecting seat moves the drive slide rod to move, and the drive slide rod moves the contact base to move. When the contact base moves to contact the ground, the reaction force of the ground on the contact base causes the contact base to slide along the side of the fixed pipe, thereby driving the drive rod to move. The drive rod moves the sliding hole to move, the sliding hole moves the rotating seat to move, and the rotating seat moves the expanding cone to rotate along the side of the fixed seat, thereby causing the expanding cone to unfold. After the expanding cone penetrates the ground to a certain depth, it unfolds, and the powdered fertilizer is then applied. Under the action of force, the fertilizer enters the interior of the insulation pipe along the inner wall of the hollow telescopic rod and then enters the side of the guide groove, thus directly entering the ground for targeted topdressing. During the movement, when the contact base leaves the ground, the elastic force provided by the first spring drives the drive slide rod downward, which in turn drives the drive rod downward. The drive rod's movement drives the sliding hole, thereby causing the rotating seat to return to its original position. This keeps the expansion cone closed again, and at this time, the through hole of the hollow telescopic rod and the rotating cylinder are misaligned. At this point, the powdered fertilizer stops entering the hollow telescopic rod, thus preventing waste and achieving precise topdressing at the designated location. The second slide groove restricts the sliding trajectory of the drive slide rod, and the insulation pipe keeps the powdered fertilizer warm, preventing it from clumping and affecting the topdressing effect. This also avoids the clogging problem caused by the traditional duckbill-style perforation design, facilitating long-term continuous operation.

[0014] 4. This potato-soybean strip planting potato topdressing machine is equipped with a handle turntable. The handle turntable drives the screw to rotate, and the screw rotation causes the first moving seat to move closer to or away from the second moving seat, thereby causing the first connecting plate to move closer to or away from the second connecting plate. This causes relative movement between the lower bottom plate and the upper top plate, thereby adjusting the distance between the support plate and the lower bottom plate, thus achieving topdressing operations at different intervals. When the electric air pump is started, the electric air pump drives the fertilizer to flow along the feed hole, thereby driving the stirring blade to rotate. The rotation of the stirring blade drives the fertilizer to stir, thereby mixing the powdered fertilizer and avoiding insufficient fertilizer mixing that would affect the fertilization effect.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-2The present invention provides a technical solution: a potato topdressing machine for potato and soybean strip planting, comprising a fertilizer box 1, a topdressing device 2 rotatably connected to the side of the fertilizer box 1 via a bracket, an extraction device 3 rotatably connected to the side of the topdressing device 2, a fixed end of a spring telescopic rod 5 fixedly connected to the top of the fertilizer box 1, an equipment bracket 4 fixedly connected to the movable end of the spring telescopic rod 5, and a roller 6 fixedly connected to the bottom of the equipment bracket 4.

[0019] Fertilizer box 1 stores powdered fertilizer. Topdressing device 2 guides the powdered fertilizer and enlarges the holes at the fertilization location to accurately inject the powdered fertilizer into the designated position. It also enlarges the holes in the ground through corresponding components to improve fertilizer utilization. Compared with the traditional duckbill-style soil breaking method, it prevents soil from clogging the delivery hole, thus avoiding additional manual cleaning. The spacing of the topdressing can be adjusted through corresponding components to adapt to different topdressing situations. The cooperation between the equipment support 4, the spring telescopic rod 5, and the roller 6 maintains the stable position of fertilizer box 1. The extraction device 3 stirs the powdered fertilizer inside fertilizer box 1 to avoid insufficient mixing of powdered fertilizer, which may lead to excessive local fertilizer content and affect the topdressing effect.

[0020] The topdressing device 2 includes a lower base plate 201, with an arc-shaped sliding hole 202 on the top of the lower base plate 201. An upper top plate 203 is rotatably connected to the top of the lower base plate 201. A straight sliding hole 204 is opened on the top of the upper top plate 203. A guide component 205 is slidably connected to the inner wall of the straight sliding hole 204. A topdressing component 206 is fixedly connected to the side of the guide component 205. An adjustment component 207 is fixedly connected to the side of the lower base plate 201. The side of the extraction device 3 communicates with the side of the guide component 205. The side of the lower base plate 201 is rotatably connected to the side of the fertilizer box 1 through a bracket.

[0021] The adjustment component 207 is manually rotated, which causes relative movement between the lower base plate 201 and the upper top plate 203, thereby moving the guide component 205. The movement of the guide component 205 moves the topdressing component 206, thereby changing the spacing between multiple sets of topdressing components 206, thus enabling topdressing operations at different spacings. The characteristics of the adjustment component 207 ensure that it remains in a fixed position after adjustment, facilitating continuous operation. The guide component 205 is used to adjust the position of the topdressing component 206 and intermittently supply water to the topdressing component 206, thereby preventing the waste of powdered fertilizer when topdressing is not performed.

[0022] Please see Figures 1-3The present invention provides a technical solution: the guide assembly 205 includes a sliding base 2051, a limiting rod 2052 is fixedly connected to the center of the bottom of the sliding base 2051, limiting slide bars 2053 are fixedly connected to the bottom of the sliding base 2051 on both sides of the limiting rod 2052, a support plate 2054 is fixedly connected to one side of the top of the sliding base 2051, a hollow telescopic rod 2055 is passed through and fixedly connected to the side of the support plate 2054, and the fixed end of the hollow telescopic rod 2055 is connected to a fixing cylinder 2056. A rotating cylinder 2057 is rotatably connected to the inner wall of the cylinder 2056. The side of the rotating cylinder 2057 is provided with a through hole that matches the hollow telescopic rod 2055. The bottom of the rotating cylinder 2057 is connected to the side of the extraction device 3. The lower bottom plate 201 and the upper top plate 203 are sleeved on the side of the fixed cylinder 2056 and rotatably connected to the fixed cylinder 2056. The sliding base 2051 is slidably connected to the top of the upper top plate 203 through the limiting slide strip 2053. The side of the support plate 2054 away from the hollow telescopic rod 2055 is fixedly connected to the side of the topdressing component 206.

[0023] Powdered fertilizer is introduced through a rotating cylinder 2057, which is fixed to the extraction device 3, allowing relative rotation between the rotating cylinder 2057 and the fixed cylinder 2056. This allows the powdered fertilizer to enter the hollow telescopic rod 2055 and then into the topdressing component 206 when the through hole on the side of the rotating cylinder 2057 connects with the fixed end of the hollow telescopic rod 2055, thus facilitating the extraction of the powdered fertilizer. A limiting rod 2052 guides the sliding base 2051, guided by the combined action of the arc-shaped sliding hole 202 and the straight sliding hole 204. This allows the limiting rod 2052 to drive the sliding base 2051 to slide on the top of the upper plate 203, and prevents the sliding base 2051 from detaching from the surface of the upper plate 203 under the restriction of the limiting sliding strip 2053. The topdressing component 206 is supported by the support plate 2054, facilitating the drilling and topdressing.

[0024] Please see Figures 1-6 The present invention provides a technical solution: the topdressing component 206 includes an insulation pipe 2061, a fixing pipe 2062 is sleeved and fixedly connected to the side of the insulation pipe 2061, a first sliding groove 2063 is opened on the side of the fixing pipe 2062, a driving component 2064 is slidably connected to the inner wall of the first sliding groove 2063, a hole-expanding component 2065 is fixedly connected to the bottom of the insulation pipe 2061, the driving component 2064 is slidably connected to the hole-expanding component 2065 through a sliding shaft, the top of the fixing pipe 2062 is fixedly connected to the side of the support plate 2054, and the top of the insulation pipe 2061 is connected to the movable end of the hollow telescopic rod 2055.

[0025] The drive assembly 2064 includes a drive slide rod 20641, a contact base 20642 fixedly connected to the bottom of the drive slide rod 20641, a second slide groove 20643 opened on the side of the drive slide rod 20641, a drive rod 20644 fixedly connected to the side of the drive slide rod 20641, a connecting seat 20645 fixedly connected to the top of the drive slide rod 20641, a first spring 20646 fixedly connected to the top of the connecting seat 20645, one end of the first spring 20646 away from the connecting seat 20645 being fixedly connected to the side of the fixing tube 2062, and a slide bar adapted to the second slide groove 20643 being fixedly connected to the side of the fixing tube 2062.

[0026] The enlarging assembly 2065 includes a fixed base 20651, a rotating base 20654 rotatably connected to the side of the fixed base 20651 via a rotating shaft, a sliding hole 20655 on the side of the rotating base 20654, an enlarging cone 20652 fixedly connected to the bottom of the rotating base 20654, a guide groove 20653 on the side of the enlarging cone 20652, a fixed top of the fixed base 20651 fixedly connected to the bottom of the fixed tube 2062, and a second sliding groove 20643 slidably connected to the rotating base 20654 via the sliding hole 20655.

[0027] When the bottom plate 201 rotates as a whole, the top plate 203 drives the limiting rod 2052 to rotate. The rotation of the limiting rod 2052 causes the support plate 2054 to rotate along the rotation center of the bottom plate 201. The through hole of the rotating cylinder 2057 points downward. The support plate 2054 drives the insulation pipe 2061 to move. The insulation pipe 2061 drives the fixing pipe 2062 to move. The fixing pipe 2062 drives the first spring 20646 to move. The first spring 20646 drives the connecting seat 20645 to move. The movement of the connecting seat 20645 drives the drive slide rod 20641 to move. The movement of the drive slide rod 20641 drives the contact base 2064. 2. Movement: When the contact base 20642 moves to contact the ground, the reaction force from the ground causes the contact base 20642 to slide along the side of the fixed tube 2062, thereby driving the drive rod 20644 to move. The movement of the drive rod 20644 causes the sliding hole 20655 to move, which in turn causes the rotating seat 20654 to move. The movement of the rotating seat 20654 causes the expanding cone 20652 to rotate along the side of the fixed seat 20651, thereby causing the expanding cone 20652 to unfold. After the expanding cone 20652 penetrates the ground to a certain depth... The expanding cone 20652 unfolds, and the powdered fertilizer, under the influence of gravity, enters the interior of the insulation pipe 2061 along the inner wall of the hollow telescopic rod 2055 and then into the side of the guide groove 20653, thus directly entering the ground for targeted fertilization. During the movement, when the contact base 20642 leaves the ground, the elastic force provided by the first spring 20646 drives the drive slide rod 20641 downwards. The downward movement of the drive slide rod 20641 drives the drive rod 20644 downwards, which in turn drives the sliding hole 20655, thereby moving the rotating seat 2065. 4. Returning to its original position, the expansion cones 20652 are re-closed, and the through holes of the hollow telescopic rod 2055 and the rotating cylinder 2057 are misaligned. At this time, the powdered fertilizer stops entering the hollow telescopic rod 2055, thus preventing waste of the powdered fertilizer and achieving precise topdressing at the designated location. The sliding trajectory of the drive slide rod 20641 is restricted by the second slide groove 20643, and the powdered fertilizer is kept warm by the heat insulation pipe 2061, thus preventing the powdered fertilizer from clumping and affecting the topdressing effect. It also avoids the clogging problem caused by the traditional duckbill-style perforation design, thus facilitating long-term continuous operation.

[0028] Please see Figures 1-8The present invention provides a technical solution: the adjustment component 207 includes a first movable seat 2071, the top of the first movable seat 2071 is rotatably connected to a first connecting plate 2072 via a rotating shaft, the side of the first movable seat 2071 is rotatably connected to a screw 2073, the side of the screw 2073 is sleeved and threadedly connected to a second movable seat 2074, the top of the second movable seat 2074 is rotatably connected to a second connecting plate 2075 via a rotating shaft, the end of the screw 2073 away from the second movable seat 2074 is fixedly connected to a handle turntable 2076, the side of the first connecting plate 2072 is fixedly connected to the side of the lower base plate 201, and the side of the second connecting plate 2075 is fixedly connected to the side of the upper top plate 203.

[0029] The extraction device 3 includes an electric air pump 301. The feed end of the electric air pump 301 is connected to a feed pipe 302. A feed hole 303 is opened on the side of the feed pipe 302. A rotating ring 304 is sleeved and rotatably connected to the side of the feed pipe 302 at the position of the feed hole 303. An agitator blade 305 is fixedly connected to the side of the rotating ring 304. The discharge end of the electric air pump 301 is connected to a discharge pipe 306. The end of the discharge pipe 306 away from the electric air pump 301 is connected to a rotating cylinder 2057. The bottom of the electric air pump 301 is slidably connected to the inner wall side of the fertilizer box 1.

[0030] Rotating the handle turntable 2076 causes the screw 2073 to rotate. The rotation of the screw 2073 causes the first movable seat 2071 to move closer to or further away from the second movable seat 2074, thereby causing the first connecting plate 2072 to move closer to or further away from the second connecting plate 2075. This causes relative movement between the lower bottom plate 201 and the upper top plate 203, thereby adjusting the distance between the support plate 2054 and the lower bottom plate 201, thus achieving topdressing operations at different intervals. Starting the electric air pump 301 causes the fertilizer to flow along the feed hole 303, thereby causing the stirring blade 305 to rotate. The rotation of the stirring blade 305 stirs the fertilizer, thereby mixing the powdered fertilizer and avoiding insufficient mixing of fertilizer which would affect the fertilization effect.

[0031] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
