Description

Technical Field

[0001] The invention relates to a rice transplanting mechanism. Background Art

[0002] In the field of rice cultivation, the growth of good varieties into strong seedlings and plants has a direct or indirect impact on the high-quality and efficient supporting seedling management model and the corresponding planting and cultivation measures; the quality of seedlings, the quality of transplanting, and the growth rate and quality of seedlings after they turn green ultimately determine the high yield and high quality and efficiency of rice. In recent years, due to the continuous changes in the supply-side structural reform of agriculture, the continuous improvement of rice production technology requirements, the continuous improvement of machine transplanting seedling raising models and methods, and the rapid development of machine transplanting high-yield cultivation technology, a variety of rice seedling raising methods and corresponding machine transplanting cultivation technology models have been formed in production. Most of these seedling raising models use soft plastic tray seedling raising, hard plastic tray seedling raising or pot plastic tray seedling raising, and the machine transplanting model is mostly seedling separation and soil cutting; although these seedling raising models and methods and their supporting technologies are also constantly undergoing great adjustments and changes, the existing technologies of these models still have certain defects and deficiencies in actual production. Soft plastic tray seedling raising, hard plastic tray seedling raising or pot plastic tray seedling raising are all plastic tray seedling raising. The use of plastic seedling trays has led to a large number of waste seedling trays, and the waste seedling trays are discarded at will, causing certain environmental pollution. At the same time, when raising seedlings, the seedling trays are generally placed horizontally, so in the middle and late stages of seedling raising, the ventilation and heat dissipation effects of the seedlings inside the seedling tray are poor due to the blocking effect of the outer seedlings, which in turn affects the late growth of the seedlings in the middle of the seedling tray. Furthermore, the existing mechanical transplanting mode requires the seedlings to be taken out of the seedling tray, and then placed on the seedling tray of the transplanter for transplanting. This method is relatively cumbersome and is not conducive to the further realization of the integrated automation technology of seedling raising and transplanting. Summary of the invention

[0003] The object of the present invention is to provide a rice transplanting mechanism. The strip-shaped degradable seedling plug tray in the seedling raising device will be naturally decomposed after a period of time after being planted in the field along with the seedlings, thereby avoiding the environmental pollution problem caused by the existing plastic seedling raising tray. The strip-shaped degradable seedling plug tray is distributed in a high and low spiral on the conical supporting plate, thereby ensuring the ventilation and heat dissipation effect of each seedling.

DETAILED DESCRIPTION

[0027] The following will be combined with specific embodiments and attached Figure 1-11 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the present invention, rather than all the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] The present invention provides a rice vertical seedling device (such as Figure 1 As shown), it includes a vertical central tube 1, a conical supporting plate 2, and a strip-shaped degradable seedling plug tray 3. The strip-shaped degradable seedling plug tray 3 described in the present invention refers to a seedling plug tray in a strip shape, and the raw materials used to manufacture the seedling plug tray are materials that can be self-degraded in the natural environment of the paddy field. In this specific embodiment, the raw materials for manufacturing the strip-shaped degradable seedling plug tray 3 can be the raw materials used for a degradable seedling plug tray published in the Chinese invention patent with announcement number CN105724108B. The raw materials of the seedling plug tray are composed of deinked pulp, plant fiber and adhesive. The water content of the deinked pulp is 40-60%, and the mass ratio of the deinked pulp, the plant fiber and the adhesive is 60-80:20-40:1.5-2. The plant fiber is composed of rice straw, reed, bulrush and wheat straw, and the mass ratio of rice straw, reed, bulrush, wheat straw and adhesive is 10:10:15:5:1.5-2. The seedling plug tray composed of the above raw materials can be naturally disintegrated within a certain number of days after being placed in a paddy field, thereby achieving subsequent natural degradation. Several of the conical supporting plates 2 are detachably arranged on the vertical center tube 1 from top to bottom. In the present specific embodiment, four conical supporting plates 2 are arranged on the vertical center tube 1, and the middle parts of the conical supporting plates 2 are all sleeved on the vertical center tube 1, and the conical supporting plates 2 can slide up and down on the vertical center tube 1. In order to facilitate the placement and removal of the four conical supporting plates 2 on the vertical center tube 1, a support rod 12 for supporting the positioning of the conical supporting plates 2 is arranged on the vertical center tube 1. The support rod 12 is connected to the side wall of the vertical center tube 1 in a threaded connection manner, that is, when the conical supporting plate 2 needs to be placed on the vertical center tube 1, the corresponding support rod 12 is screwed into the threaded hole set on the vertical center tube 1 in turn, and when the conical supporting plate 2 needs to be removed from the vertical center tube 1, the support rod 12 is unscrewed from the vertical center tube 1 in turn, which can facilitate the conical supporting plate 2 to be detached from the upper part of the vertical center tube 1.

[0029] The bottom of the vertical center tube 1 is in a closed state, and a plurality of nutrient solution output holes 11 located on the vertical center tube are arranged above each of the conical supporting plates 2. When the device is used for seedling cultivation, the configured nutrient solution flows from the nutrient solution output holes 11 to the corresponding conical supporting plates 2, thereby realizing the nutrient transportation during the seedling cultivation process. During the nutrient solution transportation process, the influence of gravity on the nutrient solution is taken into consideration. At the same time, to ensure that each conical supporting plate 2 can obtain sufficient nutrient solution, the flow area of ​​the nutrient solution output hole 11 located above the corresponding conical supporting plate 2 is made larger than the flow area of ​​the corresponding nutrient solution output hole 11 located below it. In this specific implementation, the shape of the nutrient solution output hole 11 can be circular or rectangular, and the size of the circular or rectangular flow area can be determined in turn according to the size of the actual conical supporting plate 2 and the vertical center tube 1.

[0030] A layer of seedling matrix is ​​laid on each of the conical carrier plates 2, and each of the strip-shaped degradable seedling plug trays 3 includes a plurality of seedling pots 31 connected in sequence to each other. Two strip-shaped degradable seedling plug trays 3 are placed on each of the conical carrier plates 2, and the two degradable seedling plug trays 3 are spirally wound on the conical carrier plate 2 in a double-row parallel manner, and the central axis of the seedling pot 31 is parallel to the central axis of the conical carrier plate 2. In actual application, the nutrient solution output hole 11 flows out of the nutrient solution. The liquid flows directly into the seedling matrix on the conical carrier plate 2, and the seedling matrix in the seedling pot 31 absorbs the nutrient solution from the seedling matrix on the conical carrier plate 2, and then meets the growth needs of the seeds in the seedling pot 31. In order to achieve the stable placement of the seedling matrix on the conical carrier plate 2, a detachable annular baffle 21 is provided at the outer edge of each of the conical carrier plates 2. Further, when the seedling matrix fully absorbs the nutrient solution, in order to discharge the excess nutrient solution, a plurality of drainage holes 22 are provided on the conical carrier plate 2. The present invention utilizes a vertical central tube 1 to transport the nutrient solution, thereby preventing the entire seedling pot 31 from contacting the operating liquid, thereby reducing the contact degree of the seedling pot 31 with the nutrient solution during the seedling raising process, and then maintaining the overall strength of the seedling pot 31, so as to realize the subsequent rotation separation of the strip-shaped degradable seedling hole tray 3.

[0031] In this specific embodiment, the seedling pot body 31 can be set to a circular or hexagonal shape. Furthermore, in order to facilitate the vertical center tube 1 to drive the movement of the conical supporting plate 2 to improve the seedling management, a supporting base plate 12 is set at the bottom of the vertical center tube 1, and a plurality of universal wheels 121 with braking devices are set at the lower part of the supporting base plate 12.

[0032] The present invention also provides a rice transplanting mechanism, which includes a conical carrying plate 2, a fixed support frame 4, a movable support frame 5, a supporting transverse axis 6, a pot body separation and conveying mechanism, a pot body separation and straightening mechanism and a furrow opener 9. The conical carrying plate 2 is provided with two strip-shaped degradable seedling plug trays 3 which are spirally wound side by side. At this time, the seedlings in the strip-shaped degradable seedling plug trays 3 have reached the seedling growth requirements. The fixed support frame 4 is fixedly arranged on the traction mechanism. In actual application, the fixed support frame 4 is driven by the traction mechanism to realize the movement of the entire rice transplanting mechanism. Four fixed guide rods 41 are arranged on the fixed support frame 4. The movable support frame 5 is arranged on the corresponding fixed guide rods 41 on all sides. Two hydraulic cylinders 42 are provided, and the fixed ends of the hydraulic cylinders 42 are fixedly connected to the fixed support frame 4, and the movable ends of the hydraulic cylinders 42 are connected to the bottom plane of the movable support frame 5. Through the reciprocating action of the hydraulic cylinders 42, the movable support frame 5 can be reciprocated along the axial direction of the fixed guide rod 41. A support plate 51 is respectively arranged on the front and rear sides of the upper part of the movable support frame 5, and the support transverse axis 6 is sleeved on the two support plates 51. The conical supporting disk 2 can be sleeved on the support transverse axis 6, and the conical supporting disk 2 can rotate freely on the support transverse axis 6. When the conical supporting disk 2 is sleeved on the support transverse axis 6, the strip-shaped degradable seedling hole tray is still wrapped around the conical supporting disk 2, but the seedling pot body 31 thereon and the seedling pot body 31 inside The seedlings are distributed in a tilted state. In practical applications, in order to facilitate the continuous transplanting operation of the rice transplanter within a certain period of time, a first limit pin 61 and a second limit pin 62 are provided at the rear end of the support transverse axis 6. The second limit pin 62 and the first limit pin 61 are distributed front and back on both sides of the corresponding support plate 5. The first limit pin 61 and the second limit pin 62 are used to realize the lateral positioning of the support transverse axis 6 on the movable support frame 5. A fourth limit pin 64 and a third limit pin 63 distributed in a front and back state are provided in the middle part of the support transverse axis 6. A fifth limit pin 65 located at the rear side of the corresponding support plate 51 is provided at the front end of the support transverse axis 6. The first limit pin 61, the second limit pin 62, the third limit pin 63, the fourth limit pin The limit pin 64 and the fifth limit pin 65 can both be fixed and disassembled on the support horizontal axis 6, which makes it easy to move the conical supporting plate 2 on the support horizontal axis 6 according to actual needs. The second limit pin 62 and the third limit pin 63 are between the seedling standby area, and multiple conical supporting plates 2 with strip-shaped degradable seedling hole trays can be placed in the seedling standby area, that is, the seedling standby area is used to provide seedlings to be transplanted. The seedling release area is between the third limit pin 63 and the fourth limit pin 64, and only one conical supporting plate 2 with a strip-shaped degradable seedling hole tray 3 can be stored in the seedling release area, and the conical supporting plate 2 is distributed in a conical forward state in the seedling release area. The empty plate storage area is between the fourth limit pin 64 and the fifth limit pin 65.The empty tray storage area is used to store multiple conical carrier trays 2 without strip-shaped degradable seedling plug trays 3. Through the arrangement of the seedling standby area, seedling release area and empty tray storage area, the intermittent continuous supply process of seedlings during the transplanting process can be ensured.

[0033] The bowl body separation and conveying mechanism includes a connecting main frame 71 and two groups of cutting and clamping mechanisms 72. The upper part of the connecting main frame 71 is fixedly connected to the movable support frame 5, and the connecting main frame 71 is located below the middle part of the movable support frame 5. The two groups of cutting and clamping mechanisms 72 are arranged side by side on the connecting main frame 71. Each group of cutting and clamping mechanisms 72 includes two synchronous belts 721. The two synchronous belts 721 are distributed in a vertical state side by side on the left and right, and the opposite surfaces of the two synchronous belts 721 can move downward synchronously. In this specific embodiment, the specific implementation method for realizing the rotation of the synchronous belt 721 is as follows: a driven synchronous wheel 722 and an active synchronous wheel 723 distributed up and down are provided on the connecting main frame 71, and the synchronous belt 72 The driven synchronous wheel 722 and the active synchronous wheel 723 are sleeved on the driven synchronous wheel 722 and the active synchronous wheel 723, and the active synchronous wheel 723 is rotated by the driving motor 724 arranged on the connecting main frame 71. The rotation of the active synchronous wheel 723 then realizes the rotation of the synchronous belt 721. A plurality of semicircular grooves 7211 distributed at equal intervals are arranged on each of the synchronous belts 721, and the semicircular grooves 7211 on the opposite surfaces of the two synchronous belts 721 in the same cutting and clamping mechanism 72 all move downward in a one-to-one corresponding state. The center distance between the two adjacent semicircular grooves 7211 on the same synchronous belt 721 corresponds to the center distance between the two adjacent seedling pots 31 on the belt-shaped degradable seedling plug tray 3, thereby ensuring that the synchronous belt 72 During operation, the semicircular card grooves 7211 thereon can realize the clamping and fixing of the seedling pot body 31 one by one. The two semicircular card grooves 7211 on the opposite surfaces of the two synchronous belts 721 can clamp one of the seedling pot bodies 31 to move downward, and in the process of the two semicircular card grooves 7211 docking to clamp the seedling pot body 31, the corresponding seedling pot body 31 and the strip-shaped degradable seedling plug tray 3 can be cut and separated synchronously. In order to facilitate the clamping and separation of the adjacent seedling pot bodies 31 by the semicircular card grooves 7211, arc grooves 7212 and cutting blades 7213 are provided on the semicircular card grooves 7211. The two arc grooves 7212 can clamp the seedling pot body 31 during the carding process. When the two cutting blades 7213 are butted together, since the gap between the two butting blades 7213 is very small, after they are butted in place, the connecting belt connecting the two seedling pots 31 is cut off, thereby realizing the separation of adjacent seedling pots 31. In the process of the seedling pot 31 moving downward at a uniform speed along with the synchronous belt 721, in order to further realize the stability of the movement of the seedling pot 31, a pot body auxiliary sliding groove 725 is arranged directly behind the two synchronous belts 721 in each group of the cutting and clamping mechanism 72. The pot body auxiliary sliding groove 725 is U-shaped, and the opening of the pot body auxiliary sliding groove 725 faces the relative gap between the two synchronous belts 721, and the bottom of the seedling pot 31 slides inside the auxiliary sliding groove 725.

[0034] The pot body separation and straightening mechanism includes a separator 8 with a triangular cross-section, the separator 8 is arranged directly below the two groups of the cutting and clamping mechanisms 72, and the separator 8 can realize the mutual isolation of the two seedling pots 31 that fall from the two groups of the cutting and clamping mechanisms 72. Specifically, the separator 8 is fixedly connected to the connecting main frame 71 through a first connecting plate 82, and an inclined straightening plate 81 is arranged on the two opposite surfaces of the upper part of the separator 31. The upper inclined surface of the straightening plate 81 faces the synchronous belt 721. The straightening plate 81 has a blocking and adjusting effect on the seedling pot 31 falling in a horizontal state, so that the seedling pot 31 can be kept after being blocked. It continues to fall downward in an almost vertical state, thereby facilitating the seedlings to maintain a vertical planting state in the field; the furrow opener 9 is arranged on the rear side below the partition 8, and the furrow opener 9 is in a triangular cone shape, and the furrow opener 9 is distributed in a state of low rear and high front. Specifically, the furrow opener 9 is fixedly connected to the connecting main frame 71 through a second connecting plate 91. When performing furrowing operations, the lower end of the furrow opener 9 is inserted into the field. As the furrow opener 9 moves, furrowing is achieved. The two falling seedling pots 31 fall into the grooves opened by the furrow opener 9 under the action of gravity. The grooves have a certain depth, which is convenient for storing water, thereby facilitating the green growth of the seedlings in the seedling pot 31. When the rice transplanting work is not being carried out, the movable support frame 5 is raised by the hydraulic cylinder 42, thereby raising the furrow opener 9, so that the furrow opener 9 is higher than the ground, and then the furrow opener 9 does not hinder the movement of the rice transplanter along the road with the traction mechanism. At the same time, the furrowing depth of the furrow opener 9 can also be controlled by utilizing the lifting and lowering action of the hydraulic cylinder 42 so that there is appropriate amount of water in the opened furrow.

[0035] When the rice transplanter starts working, all the conical carrier plates 2 with seedlings are removed from the vertical central tube 1 in sequence and transported to the transplanting site. Then, a conical carrier plate 2 with a strip-shaped degradable seedling plug tray 3 is placed on the seedling release area of ​​the supporting horizontal axis 6. Then, multiple conical carrier plates 2 with strip-shaped degradable seedling plug trays 3 are placed in sequence on the seedling standby area of ​​the supporting horizontal axis 6. After the above placement is completed, the annular baffle 21 on the conical carrier plate 2 on the seedling release area is removed, so that the two-day strip-shaped degradable seedling plug tray 3 on it can be placed on the seedling standby area of ​​the supporting horizontal axis 6. The outer ring movable end of the seedling cultivation plug tray 3 moves freely downward under the action of gravity, and then, the movable end seedling cultivation pot bodies 31 of the two strip-shaped degradable seedling cultivation plug trays 3 are manually assisted to be respectively clamped in the corresponding semicircular clamping grooves 7211 on the corresponding two synchronous belts 721 (at this time, the two semicircular clamping grooves 7211 have not been completely docked in place, so as to ensure that the arc grooves 7211 on the two semicircular clamping grooves 7211 have a clamping effect on the two sides of the seedling cultivation pot body 31, and the connection belt connecting the two seedling cultivation pot bodies 31 will not be cut. The drive motor 724 is then started, and the drive motor 724 drives the synchronous belt 721 to rotate. During the rotation of the synchronous belt 721, the corresponding conical carrier plate 2 can be slowly rotated through the pulling action of the belt-shaped degradable seedling hole tray 3. The slow rotation of the conical carrier plate 2 is conducive to the slow transportation of the belt-shaped degradable seedling hole tray 3 into the synchronous belt 721. During the movement of the synchronous belt 721, when the two opposing semicircular slots 7211 are fully docked in place, the two cutting blades 7213 are also realized during the docking process. The connecting belt connecting the two seedling pots 31 is cut off, thereby realizing the separation of the seedling pots 31. With the continuous operation of the synchronous belt 721, the seedling pots 31 can continuously enter the corresponding semicircular grooves 721. When the seedling pots 31 move to the lower end of the synchronous belt 721, the seedling pots 31 are separated from the semicircular grooves 721 and directly fall into the grooves opened by the furrow opener 9. By controlling the forward speed of the traction mechanism and the speed ratio of the synchronous belt 721 to continuously output the seedling pots 31, the uniform planting of the seedlings is realized.

[0036] When all the strip-shaped degradable seedling hole trays 3 in the seedling release area have entered the semicircular slots 7211 on the synchronous belt 721, the empty conical supporting plate 2 will be directly pushed into the empty plate placement area. Then, a conical supporting plate 2 with a strip-shaped degradable seedling hole tray 3 in the seedling storage area will be placed in the seedling release area, and the operation process of manually assisting the seedling pot body 31 to be clamped on the synchronous belt 721 will be repeated, and then the rice transplanting operation can be continued.

[0037] In the present invention, "upper", "lower", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0038] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0039] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the present invention, but the present invention is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
