Description

Technical Field

[0001] The invention relates to the technical field of sowing, in particular to a film-side planting shallow-buried drip irrigation seeder. Background Art

[0002] When planting wheat, the film-side seeding technique (planting on both sides of the mulch) is a crucial measure for coping with adverse conditions such as drought and cold weather, and is particularly widely used in regions such as Qinghai and Gansu. This technique, by creating furrows on both sides of the mulch for seeding, not only utilizes the mulch to raise ground temperature and reduce evaporation, but also prevents high temperatures under the mulch from inhibiting seed germination, facilitating subsequent topdressing and irrigation. Before sowing, wheat seeds must be thoroughly mixed with pesticides (such as a pentamethylenetetrachloride / imidacloprid suspension seed coating for take-all disease control and thiamethoxam for aphid control) to achieve early disease and insect pest control.

[0003] At present, traditional mixing equipment mostly uses a single power source when mixing wheat seeds and pesticides, and only relies on the continuous rotation of the central axis, which leads to obvious defects in the mixing process. In particular, although single rotary stirring can drive the overall flow of seeds, "mixing dead corners" are easily formed in the edge areas. Under the action of centrifugal force, the pesticides are easy to gather towards the center, resulting in insufficient adhesion of the pesticides to the edge seeds, which also directly affects the germination rate and seedling resistance of wheat.

[0004] To this end, we proposed a film-side planting shallow buried drip irrigation seeder to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0030] Example 1, with reference to Figures 1 to 4 , which is the first embodiment of the present invention.

[0031] Specifically, the sowing assembly 100 includes a frame 101, running wheels 1011 provided on the frame 101, two crossbeams 102 screwed to the frame 101, and a discharge member 103 provided on the outer wall of the crossbeam 102; wherein, a soil breaking blade 1021 and a soil covering wheel 1022 are respectively installed on the two crossbeams 102 by bolts;

[0032] The travel wheels 1011 support the movement of the entire seeder, which is also equipped with drip irrigation components for post-seeding drip irrigation. These travel wheels 1011 are powered by a diesel engine (this is well documented in the prior art and will not be elaborated upon here). During seeding, the soil-breaking blades 1021 break up the soil on both sides of the film, followed by the discharging member 103 for intermittent sowing, which is then covered with soil by the covering wheels 1022.

[0033] It should be noted that before sowing, the wheat seeds and the medicine in the frame 201 need to be mixed by the supporting assembly 200. Sowing can only be done after the mixture is evenly mixed. The discharge member 103 is also provided with a solenoid valve for opening or closing the discharge channel.

[0034] The supporting assembly 200 includes a frame 201 disposed above the discharge member 103; wherein the frame 201 is used to load seeds and chemicals, and supports various components to mix the wheat seeds and chemicals.

[0035] The first stirring assembly 300 comprises a rotating ring 301 movably mounted within the frame 201 and an extension plate 302 integrally formed on the outer wall of the rotating ring 301. The first stirring assembly 300 is affected by the stirring action of the second stirring assembly 400, causing intermittent stirring. When the rotating ring 301 rotates, the extension plate 302 on the rotating ring 301 rotates synchronously, stirring a localized area within the frame 201.

[0036] The second stirring assembly 400 includes a rotating shaft 401 movably disposed in the frame 201 and a stirring blade 4011 mounted on the outer wall of the rotating shaft 401 via bolts. The rotating shaft 401 continuously stirs the vicinity of the axis of the frame 201 via the stirring blade 4011 .

[0037] Preferably, the discharging member 103 includes a receiving ring 1031 and a funnel 1032 integrally formed on the end surface of the receiving ring 1031; a distributing frame 1033 is provided below the funnel 1032. The receiving ring 1031 on the discharging member 103 is used to connect to the frame 201, and the two are detachably connected by a threaded fit, while the distributing frame 1033 is used to intermittently sow seeds.

[0038] Preferably, a sowing plate 1036 is integrally formed on the bottom of the outer wall of the distribution frame 1033. A distribution wheel 1034 is rotatably mounted within the distribution frame 1033. The outer wall of the distribution wheel 1034 is provided with a plurality of discharge troughs 1035 arranged in a circular array. Two discharge members 103 are horizontally disposed, and output shafts 104 are axially disposed on the two distribution wheels 1034. A handlebar 105 is provided on the frame 101. The mixed seeds with the drug are intermittently fed into the distribution frame 1033 through the funnel 1032.

[0039] Specifically, the dividing wheel 1034 is controlled to rotate, and each time the discharge trough 1035 on the dividing wheel 1034 rotates and passes through the funnel 1032, some seeds will be brought into the dividing frame 1033 and discharged from the discharge trough 1035 to realize the sowing action.

[0040] It should be noted that there are two horizontally arranged discharge members 103, and the middle channel of the two discharge members 103 can ensure that the film is not affected during the sowing process. The output shaft 104 can be connected to the diesel engine by means of a belt or chain.

[0041] In summary, considering that agglomerates are easily formed when seeds and agrochemicals are mixed, the continuous stirring of the second stirring assembly 400, combined with the intermittent stirring of the first stirring assembly 300, can break up agglomerates to a certain extent. This stirring method not only ensures a uniform mixing of the two, but also breaks up agglomerates with a stronger force as they form or are about to form, thereby destroying the forces that cause agglomeration between the seeds and the agrochemicals.

[0042] Example 2, reference Figures 1 to 8 , which is the second embodiment of the present invention.

[0043] Specifically, a feeding channel 2011 is formed through the outer wall of the frame 201. An output motor 203 is mounted at the end of the frame 201, with the output end of the output motor 203 connected to the rotating shaft 401. The output motor 203 serves as the power source for the second stirring assembly 400, rotating the rotating shaft 401. The feeding channel 2011 facilitates the addition of various reagents to be mixed as needed.

[0044] An installation channel 3022 is defined between every two adjacent extension plates 302 . The first stirring assembly 300 further includes a transmission member 303 . The transmission member 303 includes a fixing ring 3031 disposed at the end of the rotating ring 301 .

[0045] The transmission member 303 is provided so that the first stirring assembly 300 can generate intermittent motion in a force-accumulating manner according to the rotation of the rotating shaft 401 .

[0046] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention.

[0047] Specifically, the outer wall of the fixing ring 3031 has a plurality of protrusions 3032 arranged in a circumferential array, and the outer wall of each protrusion 3032 extends into the installation channel 3022. The protrusions 3032 are used to fill the gaps between the extension plates 302.

[0048] One of the protrusions 3032 has a slot 3033 formed on its outer wall. That is, there is only one slot 3033. When the slot 3033 engages with the insertion rod 2021, the transmission member 303 keeps the swivel 301 stationary. Once the insertion rod 2021 is released from the slot 3033, the swivel 301 rotates until the slot 3033 engages with the other insertion rod 2021.

[0049] A connecting ring 402 is sleeved on the outer wall of the rotating shaft 401, and a buffer frame 4021 is integrally formed on the outer wall of the connecting ring 402. The buffer frame 4021 is hollow, with an opening at one end. A tension spring 404 is attached to the outer wall of the buffer frame 4021, and the end of the tension spring 404 away from the buffer frame 4021 is connected to the fixing ring 3031. This tension spring 404 provides a certain force accumulation effect for the fixing ring 3031 during rotation.

[0050] A first elastic member is disposed within the buffer frame 4021, and a push rod 403 is movably disposed within the buffer frame 4021, one end of the first elastic member being connected to the push rod 403. The first elastic member is a compression spring, and the push rod 403 can be reset when it is extended or retracted within the buffer frame 4021 due to the arrangement of the first elastic member.

[0051] The outer wall of the frame 201 is formed into a circumferential array of limit frames 202, and a second elastic member is disposed within the limit frame 202. A rod 2021 is movably disposed within the limit frame 202, and one end of the rod 2021 extends into the frame 201. One end of the second elastic member is connected to the rod 2021. The second elastic member is also a compression spring, and when the rod 2021 is displaced within the limit frame 202, it also has a reset effect.

[0052] The outer wall of the rotating ring 301 is provided with a matching groove 3011, and the outer wall of the extension plate 302 is provided with a buffer block 3021. Among them, the matching groove 3011 is used for the frame 201 to support the rotating ring 301 to rotate, and the buffer block 3021 is used to increase the stirring range.

[0053] In summary, before stirring, the staff can place the wheat seeds in the receiving ring 1031, connect the frame 201 to the receiving ring 1031, and then start the output motor 203 to make the rotating shaft 401 enter a rotating state.

[0054] The rotating shaft 401 stirs the seeds in the bottom frame 1011 through the stirring blades 4011. Workers can add additional reagents to the frame 201 through the feeding channel 2011 according to actual sowing needs. During the rotation of the shaft 401, the buffer frame 4021 on the connecting ring 402 rotates synchronously with the shaft 401. The push rod 403 on the buffer frame 4021 contracts when it contacts the extension plate 302. It rebounds and resets when it passes through the extension plate 302, knocking the rod 2021 stuck in the slot 3033, causing the rod 2021 to disengage from the slot 3033. Once the rod 2021 disengages from the slot 3033, the fixing ring 3031, under the force of the tension spring 404, pulls the rotating ring 301 to rotate, thereby achieving the stirring action of the first stirring assembly 300. It should be noted that when the fixed ring 3031 rotates until the slot 3033 engages with the other insertion rod 2021, the rotating ring 301 returns to a stationary state, and the intermittent motion of the stored force is completed in this reciprocating manner.

[0055] When the push rod 403 passes through the extension plate 302 , it will come into contact with the extension plate 302 , causing the extension plate 302 to shake slightly. This shaking can also prevent materials from sticking to the extension plate 302 .

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
