Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and in particular relates to potato planting and cutting equipment. Background Art

[0002] Seed cutting is a key step in potato cultivation. Cutting seed potatoes into small pieces with buds improves seed potato utilization and promotes uniform seedling emergence. Traditional seed cutting relies heavily on manual labor, which is inefficient and labor-intensive. Furthermore, if the cutter cuts a virus-infected seed potato, it can easily transmit the virus to subsequent cuts, leading to losses in planting and, consequently, potato yield.

[0003] To address the drawbacks of manual seed cutting, various potato seed cutting devices have emerged in the prior art. These devices use mechanical structures to achieve seed potato cutting, which has improved seed cutting efficiency to a certain extent. Chinese utility model patent publication number CN215582571U discloses a potato seed cutting and breeding device for planting potatoes. The device comprises a fixed circular block and multiple cutting mechanisms located above the fixed circular block. The top outer wall of the fixed circular block is rotatably connected to a rotating shaft, and the top outer wall of the rotating shaft is equipped with a circular block. The outer wall of the circular block is also equipped with equidistantly distributed support rods. An electric telescopic rod is inserted into one side of the top outer wall of the support rod. The cutting mechanism includes a mounting frame fixed below the electric telescopic rod. The inner wall of the mounting frame is equipped with a mounting ring, and the inner wall of the mounting ring is equipped with a cutting blade frame. The utility model is provided with a drying mechanism, and the cutting knife frame is located in the disinfectant inside the disinfection shell before cutting, so as to avoid the infection of normal potatoes by pathogens when diseased potatoes are cut, thereby improving the safety of subsequent breeding. When it is needed, the cutting knife frame is lifted by the action of the electric telescopic rod, and the hydraulic rod is opened, so that the triangular sponge wiping block contacts the outer wall of the cutting knife frame, thereby absorbing water stains and the like on the outer wall of the cutting knife frame.

[0004] However, the device still has the following deficiencies: Defect 1: The feeding process of the comparative document requires placing potatoes one by one on the arc block, and then pushing the potatoes into the arc groove by an electric push rod. The entire process requires the coordination of manual and mechanical actions, and it is impossible to achieve continuous batch delivery of seed potatoes. Its seed cutting efficiency is low, and it is difficult to adapt to the efficient seed cutting needs of large-scale planting. Defect 2: The disinfection shell of the comparative document is directly connected to the external environment, without any sealing protection structure. External dust, seed potato debris, moisture, etc. are easily mixed into the disinfectant, causing the disinfectant to be contaminated and reducing the disinfection effect. At the same time, the disinfection and cutting actions of the cutting frame are completely separated: the cutting frame needs to be raised from the disinfectant and rotated to the cutting position through the rotating shaft. During this process, the surface of the cutting blade will be exposed to the air and will inevitably be contaminated with impurities or pathogens in the air. Real-time disinfection before cutting cannot be achieved, and there is still a risk of contamination of the cut surface of the seed potato. In addition, the separation of the disinfection and cutting actions of the cutting frame increases equipment redundancy, which is not conducive to the later maintenance and management of the equipment. Defect 3: Potatoes have a high starch content. After cutting, the surface of the cutter is prone to sticking to the seed potato pieces due to residual starch and disinfectant. If not cleaned in time, it will not only affect the flatness of the next cutting, but may also cause the stuck seed potato pieces to be carried away by the inertia of the cutter, resulting in seed potato waste and inconvenience in unified collection. Although the comparative document can solve this problem to a certain extent by using a triangular sponge wiping block in contact with the outer wall of the cutter frame to absorb water stains on the outer wall of the cutter frame, the anti-sticking timing is delayed and is an independent process after cutting. The anti-sticking problem is not solved synchronously during the cutting process, which increases the action steps and structural complexity of the equipment; and the anti-sticking effect is limited. The triangular sponge wiping block only absorbs moisture on the surface of the cutter frame through the water absorption of the sponge, but lacks the force of active squeezing, so its function of wiping the cutter dry to achieve anti-sticking of the cutter is limited.

[0034] like Figure 1-15 As shown, a potato planting and cutting device comprises a bearing support structure 1, which comprises a bearing plate 11; a notch 12 is provided along its width direction at the center position in the length direction of the bearing plate 11, a disinfectant shell 2 is provided above the bearing plate 11, and a cutter assembly 3 that can move up and down inside the disinfectant shell 2 is provided inside the disinfectant shell 2, the cutter assembly 3 comprises a knife group support frame 31, a knife group 32 with a blade vertically upward installed above the knife group support frame 31, and a first shaft sleeve 33 integrally formed with the center of the bottom of the knife group support frame 31; an anti-sticking support plate 4 is provided above the disinfectant shell 2, and a knife outlet 41 corresponding to the blade of the knife group 32 is provided on the upper surface of the anti-sticking support plate 4; the principle of this arrangement is: before work, disinfectant is injected into the disinfectant shell 2, and the disinfectant should at least cover the blade of the knife group 32. After being transported, the seed potatoes fall on the anti-sticking support plate 4, and at this time the knife group 32 is located in the disinfectant shell When the cutting is needed, the cutting blade 32 of the knife group 3 is driven by the knife outlet 41 of the anti-sticking support plate 4, and the cutting blade 32 is pushed up and cuts the seed potato vertically to complete the cutting action; after cutting, the cutting blade 3 is reset downward, and the blade is retracted into the disinfectant shell 2 and immersed in the disinfectant again; its function is: the cutting blade 3 moves up and down in the disinfectant shell 2 to achieve immediate disinfection after cutting, and avoids the cutting blade from being contaminated with pathogens and contaminating subsequent seed potatoes, thereby reducing the risk of disease transmission; in addition, the cooperation between the anti-sticking support plate 4 and the knife outlet 41 can quickly separate the seed block from the blade after cutting, avoid the seed block from sticking to the cutting blade due to starch residue, and improve the stability of continuous cutting; it should be noted that the shape of the knife group 32 of this embodiment is not limited to that shown in the drawings, and any knife group 32 that can achieve cutting in the prior art can be used here. For example, in order to cut more finely, a cross knife group 32 can be used.

[0035] A through hole is provided at the upper end of the knife group support frame 31, which plays a key role in reducing liquid resistance during equipment operation: when the cutter assembly 3 moves back and forth up and down in the disinfectant in the disinfectant housing 2, the through hole allows the disinfectant to pass smoothly through the knife group support frame 31, avoiding the formation of local liquid pressure difference due to the up and down movement of the support frame, thereby reducing the resistance of the liquid to the lifting and lowering movement of the cutter assembly 3. This design can reduce the driving force loss of the first cylinder 51, ensuring that the lifting and lowering movement of the cutter assembly 3 is smooth and efficient; the shape of the knife group support frame 31 is not limited to that shown in the accompanying drawings.

[0036] The bearing support structure 1 also includes a base plate 13, above which a knife group power assembly 5 is provided; the knife group power assembly 5 is the power source for driving the cutter assembly 3 to move up and down, and can drive the knife group 32 from the disinfectant through the knife outlet 41 of the anti-sticking support plate 4 to complete cutting. After completing cutting, the knife group 32 is driven back into the disinfectant to reset, thereby realizing a cycle of cutting and disinfection.

[0037] The disinfectant housing 2 includes a cylinder shaft through hole 21, a water inlet 22, a water outlet 23, and a sealing groove 24; wherein the cylinder shaft through hole 21 is opened at the center of the bottom of the disinfectant housing 2, the water inlet 22 is opened at the rear side of the disinfectant housing 2, the water outlet 23 is opened at the bottom of the disinfectant housing 2 and is located in front of the cylinder shaft through hole 21, and the water outlet 23 is provided with a pluggable plug 25 adapted to the water outlet 23; the positions of the cylinder shaft through hole 21 and the water outlet 23 correspond to the notch 12 opened at the center position of the length direction of the supporting plate 11 along its width direction; the sealing groove 24 is opened above the water outlet 23, and a sealing ring 26 is provided in the sealing groove 24; the disinfectant housing 2 contains disinfectant, and the cylinder shaft through hole 21 provides a channel for the lifting and lowering of the cutter assembly 3, which cooperates with the sealing ring 26 in the sealing groove 24 to prevent the disinfectant from leaking along the channel; The water inlet 22 is connected to the instant water tank 120 to replenish the disinfectant, and the water outlet 23 is convenient for the discharge of waste liquid, forming a complete disinfectant circulation system; the cylinder shaft through hole 21 and the water outlet 23 correspond to the notch 12 of the supporting plate 11, providing space for the movement of the knife group power component 5 and the discharge of waste liquid, and facilitating the disassembly and maintenance of each component, which is conducive to the practicality and scientific rationality of the present invention; the installation method of the disinfectant shell 2 is: the bottom of the disinfectant shell 2 is fixed to the supporting plate 11 by bolts on all sides, so as to ensure the stability of the disinfectant inside it and the stability of the knife group power component 5 and the cutter assembly 3 when working together; the sealing ring 26 in this embodiment specifically adopts a U-shaped sealing ring 26, which is adapted to the dynamic scene of the reciprocating lifting of the cutter assembly 3 in this embodiment, can automatically stick to the cover, reduce friction and have a good sealing effect.

[0038] The knife group power assembly 5 includes a first cylinder 51, a linear bearing 52, and an extended load-bearing shaft 53; wherein the first cylinder 51 is vertically fixed above the base plate 13, the linear bearing 52 is installed at the bottom of the disinfectant housing 2, and the internal channel of the linear bearing 52 is coaxial with the cylinder shaft through hole 21; a screw hole matching the output shaft of the first cylinder 51 is provided on the surface of one end of the extended load-bearing shaft 53, and the screw hole is connected with the threaded structure at the upper end of the output shaft of the first cylinder 51, and the upper shaft body of the extended load-bearing shaft 53 passes through the linear bearing 52, the cylinder shaft through hole 21, and the sealing ring 26 in sequence, and the other end of the extended load-bearing shaft 53 is fixedly sleeved in the first shaft sleeve 33; the knife group power assembly 5 is connected with the first cylinder 51 through the linear bearing 52, the cylinder shaft through hole 21, and the sealing ring 26 in sequence. The cylinder 51 provides driving force to realize the reciprocating lifting function of the cutter assembly 3. The role of the linear bearing 52 here is to provide high-precision guidance and support for extending the vertical lifting movement of the load-bearing shaft 53, and maintain coaxiality with the cylinder shaft through-hole 21 through its internal channel to ensure that the cutter assembly 3 maintains synchronous vertical precise movement during the lifting process. This design can avoid the radial deviation of the output shaft of the first cylinder 51 during movement, which causes the knife group 32 to be unable to pass through the knife outlet 41 smoothly, effectively prevents the blade from colliding and wearing with the edge of the knife outlet 41, and structurally guarantees the stability of the knife group 32 operation, ensures the stability of the equipment operation and service life, and is conducive to the practicality and scientific rationality of the present utility model.

[0039] The bearing support structure 1 also includes a top plate 14, and a blade guard pad 6 is fixedly installed on the bottom of the top plate 14 by bolts. The lower surface of the blade guard pad 6 is arranged opposite to the upper surface of the anti-sticking support plate 4, and the blade guard pad 6, the anti-sticking support plate 4, and the left and right side vertical plates of the bearing support structure 1 together form a rectangular internal channel 7; the blade guard pad 6 can be made of wood or composite material, and its function is that when the knife group 32 pushes upward to cut the seed potato, the blade guard pad 6 can support the seed potato from above, and cooperate with the bottom support of the anti-sticking support plate 4 to prevent the seed potato from shifting during the cutting process, thereby ensuring cutting accuracy; at the same time, when the knife group 32 contacts the blade guard pad 6, damage to the blade is avoided, reflecting the practicality and scientific rationality of the utility model; the blade guard pad 6, the anti-sticking support plate 4, and the left and right side vertical plates of the bearing support structure 1 together form a rectangular internal channel 7, which is an exclusive space for seed potato cutting, preventing the seed potato from falling or shifting, and ensuring stable operation of the equipment.

[0040] The supporting structure 1 is provided with a supporting platform 8 at the rear, and a discharging assembly 9 is provided above the supporting platform 8. The discharging assembly 9 includes a second cylinder 91, a cylinder shaft joint 92, a push plate 93, and a second shaft sleeve 94 integrally formed with the center of one end face of the push plate 93; wherein, a screw hole is provided on the surface of one end of the cylinder shaft joint 92, which matches the output shaft of the second cylinder 91, and the screw hole is connected with the threaded structure of the output shaft of the second cylinder 91, and the other end of the cylinder shaft joint 92 is sleeved in the second shaft sleeve 94, and the push plate 93 can move in the width direction of the rectangular internal channel 7 formed by the blade guard plate 6, the anti-sticking support plate 4, and the left and right side vertical plates of the supporting structure 1; the function of the discharging assembly 9 is to quickly push the cut seed potato pieces out of the equipment to realize continuous operation. Its working principle is as follows: the second cylinder 91 is connected to the cylinder shaft joint 92 through the threaded structure of the output shaft The push plate 93 is connected to the left and right sides of the rectangular internal channel 7 to transmit the driving force to the push plate 93. When the second cylinder 91 is started, the push plate 93 is translated along the width direction of the rectangular internal channel 7, and the space formed by the blade guard plate 6 and the anti-sticking support plate 4 is used to push the cut seed potato blocks from the back side of the rectangular internal channel 7 to the front side, thereby pushing the seed potato blocks to the specified position, and then the push plate 93 returns to its original position under the action of the second cylinder 91; before the second cylinder 91 is started, the push plate 93 is located at the back side of the rectangular internal channel 7 formed by the blade guard plate 6, the anti-sticking support plate 4, and the left and right side vertical plates of the load-bearing support structure 1. After the second cylinder 91 is started, the farthest stroke of the push plate 93 is that the front end face of the push plate 93 is parallel to the front end face of the load-bearing support structure 1. The shape of the push plate 93 is rectangular and matches the rectangular internal channel 7. This can ensure that the push plate 93 can smoothly push out all the seed potato blocks during operation.

[0041] The front side of the rectangular internal passage 7 is provided with an automatic door closing assembly 110, which includes a movable door 111 and an automatic door closer 112; wherein the upper end of the movable door 111 is hinged to the front side of the top plate 14 by a hinge, and the movable door 111 can cover the front side of the rectangular internal passage 7 when the movable door 111 is closed; the automatic door closer 112 includes a regulating valve 1121, a rotating and telescopic movable bracket 1122 and a limit seat 1123, wherein the regulating valve 1121 is installed on the front end surface of the movable door 111, and the limit seat 1123 is installed on the front side of the bearing support structure 1 at a position corresponding to the regulating valve 1121, and the two ends of the rotating and telescopic movable bracket 1122 are respectively connected to the regulating valve 1121 and the limit seat 1123, so as to realize the automatic closing function of the automatic door closer 112 after the movable door 111 is opened; the automatic door closing assembly 110 is used for the rectangular internal passage The dynamic opening and closing of the front side of the internal channel 7 has a protective function: the movable door 111 is hinged to the front side of the top plate 14 by a hinge, and covers the front side of the channel when closed. At this time, it forms a relatively closed space together with the rectangular internal channel 7 and the push plate 93 on the back side of the rectangular internal channel 7, which has the functions of preventing debris from entering, preventing the seed potatoes entering the rectangular internal channel 7 from falling, and preventing the seed potato blocks from being squeezed out during the seed potato cutting process; when the push plate 93 pushes out the seed blocks, the seed blocks push open the movable door 111, and the seed blocks are discharged from the front side of the rectangular internal channel 7. A container can be placed at the corresponding position for uniformly collecting the cut seed blocks. After the seed blocks are pushed out, the rotating and telescopic movable bracket 1122 of the automatic door closer 112 contracts under the action of the reset force, and cooperates with the regulating valve 1121 and the limit seat 1123 to drive the movable door 111 to close automatically; the automatic door closer 112 is a prior art and will not be described in detail.

[0042] An instant water pool 120 is fixedly arranged above the supporting platform 8. The instant water pool 120 includes a pool body 121. A water inlet 122 is provided at the bottom of the pool body 121, which penetrates the pool body 121 and the supporting platform 8. A filter screen 123 is provided inside the water inlet 122.

The water inlet 122 is connected to the water inlet 22 on the rear side of the disinfectant housing 2 through a pipe 140. The function of the instant water pool 120 is to continuously supply disinfectant to the disinfectant housing 2. The principle is as follows: the slope 124 inside the pool body 121 guides the solution to converge to the bottom, so that the disinfectant naturally flows to the water inlet 122 located at the front side of the bottom of the slope 124; the water inlet 122 is connected to the water inlet 22 on the rear side of the disinfectant housing 2. The filter 123 can filter out undissolved particles and avoid clogging the pipe 140 or contaminating the disinfectant housing 2. The water inlet 122 is connected to the water inlet 22 of the disinfectant housing 2 through the pipe 140, so as to realize the directional delivery of the filtered disinfectant and provide a liquid environment for continuous disinfection for the knife group 32; at the same time, the design of the pool body 121 is convenient for construction scenarios without direct access to a water source. Water can be directly poured in by drawing water from a bucket to replenish it, thereby improving the applicability of the equipment in different environments; for example, potassium permanganate powder can be poured directly into the instant water pool 120, and then water can be directly poured into the instant water pool 120 by drawing water from a bucket. The filter 123 accelerates the dissolution of the potassium permanganate powder, and after forming a potassium permanganate solution, it enters the disinfectant housing 2 through the pipe 140 to prepare for disinfection.

[0043] The upper ends of the left and right side vertical plates of the bearing support structure 1 are provided with feed ports 15 that are positioned opposite to each other and of the same size. Material channels 130 are provided on the outside of the feed ports 15. The extension portion 131 formed by the outer edge of the lower port of the material channel 130 extending outward is provided with a screw hole. The material channel 130 is fixedly installed on the left and right sides of the bearing support structure 1 by bolts and screw holes, so that the lower port of the material channel 130 is connected to the feed port 15; the material channel 130 cooperates with the feed port 15 to provide a directional conveying path for the seed potatoes to be cut, and its function and principle are as follows: the feed ports 15 of the left and right side vertical plates serve as the entrances for the seed potatoes to enter the rectangular internal channel 7, and the material channel 130 is provided on the outside thereof to form a conveying channel from the outside of the equipment to the rectangular internal channel 7. The seed potatoes can be fed into the rectangular internal channel 7 from above the material channel 130 to be cut.

[0044] The lower edge of the feed port 15 is higher than the horizontal position of the anti-sticking support plate 4; the lower edge of the feed port 15 is higher than the horizontal position of the anti-sticking support plate 4, and its raised part forms a limiting barrier: when the seed potatoes in the rectangular internal channel 7 are subjected to the impact force of the knife group 32 or the push force of the push plate 93 during the cutting process, the height difference can prevent the seed potatoes from sliding toward the feed port 15 on the left and right sides, thereby preventing the seed potatoes from accidentally sliding out of the feed port 15 or deviating from the cutting position; at the same time, this design neither affects the seed potatoes from smoothly entering the rectangular internal channel 7 from the feed port 15, but also ensures that the seed potatoes are stably in the channel during cutting through physical limiting, thereby ensuring cutting accuracy and equipment operation stability.

[0045] Specific working principle: the seed potatoes to be cut are fed into the feed port 15 from above the left and right material channels 130. At this time, the knife group 32 of the cutter assembly 3 is immersed in the disinfectant of the disinfectant shell 2, and the push plate 93 is located at the rear side of the channel; during cutting, the first cylinder 51 of the knife group power assembly 5 drives the extended bearing shaft 53 to rise vertically, and the extended bearing shaft 53 drives the cutter assembly 3 to rise synchronously through the first shaft sleeve 33; the linear bearing 52 provides high-precision guidance for the extended bearing shaft 53 to ensure the vertical movement of the cutter assembly 3, so that the blade of the knife group 32 accurately passes through the knife outlet 41 of the anti-sticking support plate 4, and cooperates with the blade guard pad 6 to limit the upper part of the seed potato to complete the top cutting action; after cutting, the first cylinder 51 drives the extended bearing shaft 53 to descend, and the cutter assembly 3 is reset with it, and the knife group 32 is re-immersed in the disinfectant to achieve immediate disinfection after cutting; then, the second cylinder 91 drives the push plate 93 to move horizontally along the rectangular internal channel 7, pushing the seed block forward and opening it. After that, the movable door 111 of the automatic closing assembly 110 pushes the seed block out of the channel. After the push plate 93 is reset, the movable door 111 is closed under the action of the automatic door closer 112; the instant water pool 120 replenishes the consumed disinfectant to the disinfectant housing 2 through the pipe 140. If the disinfectant is exhausted and needs to be replaced, the pluggable plug 25 of the water outlet 23 at the bottom of the disinfectant housing 2 is removed, and the waste liquid is discharged through the water outlet 23 to complete the waste liquid cleaning; thereafter, the pluggable plug of the water outlet 23 is closed, and new disinfectant and water are added to the instant water pool 120. After filtering through the filter 123, new disinfectant and water are transported to the water inlet 22 of the disinfectant housing 2 through the pipe 140 until the disinfectant submerges the blade of the knife group 32, that is, the replacement is completed. This process does not require disassembly of the core components. The convenient replacement of the disinfectant is achieved through the cooperation of water inlet and drainage, ensuring that the knife group 32 is continuously in an effective disinfection environment, maintaining the disinfection effect of the equipment, and ensuring the continuity and safety of the seed cutting operation.
