Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a tillage and fertilization machine suitable for cotton fields. Background Technology

[0002] Years of practical experience in cotton cultivation have shown that cotton is a crop that requires inter-row cultivation. During its growth process, inter-row cultivation, fertilization, and weeding are central aspects of cotton field management. A popular proverb in cotton-growing areas goes, "There's no secret to cotton cultivation; diligent inter-row cultivation and weeding are key," which fully illustrates the importance of inter-row cultivation. Furthermore, inter-row cultivation in cotton needs to be carried out multiple times at different stages of cotton cultivation.

[0003] A cotton inter-row fertilizer applicator, disclosed in the prior art with the publication number "CN206909077U", includes a main frame, a liquid fertilizer spraying mechanism, and an inter-row fertilizer mechanism. A traction frame connected to a tractor traction seat and a lifting frame connected to a tractor hydraulic lifting mechanism are fixed at the front end of the main frame. A support wheel is installed on each side of the bottom of the main frame, and the liquid fertilizer spraying mechanism is fixed on the top of the main frame. An inter-row fertilizer mechanism is located on each side of the main frame. This device integrates inter-row fertilization, weeding, and liquid fertilizer spraying, effectively reducing equipment costs and lowering costs for cotton farmers. After the tractor enters the field, it can complete inter-row fertilization, weeding, and liquid fertilizer spraying in one operation, effectively reducing the number of times the tractor enters the field and avoiding secondary compaction of the soil after weeding, thus ensuring the effectiveness of the inter-row fertilization operation.

[0004] However, the aforementioned device still has some obvious drawbacks in its use: the device achieves cultivation and fertilization through corresponding cultivation and liquid fertilizer spraying mechanisms, but it can only fertilize a single row at a time, resulting in low fertilization efficiency. Furthermore, its fertilization operation requires the drive of electrical components. In addition, the device uses liquid fertilizer for cultivation, and its spraying method is quite extensive, making it difficult to adjust according to the height of the cotton seedlings. Moreover, the device does not select different fertilization mechanisms according to the planting status of the cotton seedlings, which leads to a single fertilization method and poor fertilization effect. Summary of the Invention

[0005] The purpose of this invention is to provide a tillage and fertilization machine suitable for cotton fields, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A type of inter-row cultivation and fertilization machine suitable for cotton fields includes:

[0008] The frame has wheel frames mounted on both sides of the front end of the frame in a fixed-axis rotatable manner, and the side of the wheel frames away from the frame on both sides is equipped with a travel wheel via a rotating shaft;

[0009] The towing frame is fixedly connected to the vehicle frame and connected to the pin shaft of the towing agricultural machine, thereby driving the inter-tillage and fertilization machine to perform inter-tillage and fertilization operations through the towing agricultural machine.

[0010] Multiple inter-row cultivation and fertilization claws are fixedly and equidistantly installed at the bottom of the vehicle frame. The inter-row cultivation and fertilization claws are V-shaped, with the pointed ends of the V-shaped inter-row cultivation and fertilization claws facing the front of the vehicle body in the direction of travel. The two side plates of the inter-row cultivation and fertilization claws are separated to form a fertilization gap.

[0011] The ridge fertilization mechanism is set between multiple inter-ridge cultivation and fertilization claws. The ridge fertilization mechanism includes baffles fixedly installed on the left and right sides and a top plate that is lifted and set on the baffles on both sides. Liquid fertilizer spray holes are provided on the opposite side of the baffles and at the bottom of the top plate. The cotton crop in the ridge is sprayed and fertilized through the liquid fertilizer spray holes.

[0012] The fertilizer storage box is fixedly installed on the vehicle frame. The fertilizer storage box is divided into a water fertilizer box and a granular fertilizer box by a partition. The water fertilizer box is equipped with a water fertilizer application mechanism. The fertilizer application pipe of the water fertilizer application mechanism is connected to the liquid fertilizer spray hole installed on the baffle and the top plate. The granular fertilizer box is equipped with a granular fertilizer application mechanism. The discharge pipe of the granular fertilizer application mechanism extends to the outside of the fertilizer storage box and is set above the fertilization gap of the V-shaped inter-row cultivation fertilizer claw.

[0013] The transmission mechanism includes a main drive shaft and a secondary drive shaft, which are connected by a drive belt. The secondary drive shaft is located inside the fertilizer storage box and is connected to the water and fertilizer application mechanism and the granular fertilizer application mechanism. The main drive shaft is connected to the drive disc of the towing agricultural machine by a drive belt, and the rotation of the drive disc provides power to the water and fertilizer application mechanism and the granular fertilizer application mechanism.

[0014] Preferably, hydraulic telescopic links are also rotatably mounted on both sides of the front end of the frame. The end of the hydraulic telescopic link away from the frame is connected to a pivot on the wheel frame through a pivot hole. The height of the frame off the ground is adjusted by extending and retracting the hydraulic telescopic link.

[0015] Preferably, the main drive shaft is movably inserted into the transmission frame, the transmission frame is fixedly installed on the towing frame, and a transition drive shaft is also provided between the main drive shaft and the auxiliary drive shaft. The transition drive shaft is connected to the main drive shaft and the auxiliary drive shaft through a tire, and the auxiliary drive shaft is fixedly and rotatably disposed at the bottom of the fertilizer storage box.

[0016] Preferably, the number of the inter-row cultivation and fertilization claws is three, and the three inter-row cultivation and fertilization claws are respectively fixedly installed in the middle and on both sides of the frame. The gap between the three inter-row cultivation and fertilization claws is located at the cotton planting ridge. The ridge fertilization mechanism consists of two sets, which are respectively set at the gap formed by the separation of the three inter-row cultivation and fertilization claws.

[0017] Preferably, the fertilizer storage box is equipped with four sets of partitions, thereby dividing the inside of the fertilizer storage box into three sets of granular fertilizer boxes and two sets of water and fertilizer boxes. The three sets of granular fertilizer boxes are set above the cotton planting ridges, and the two sets of water and fertilizer boxes are set above the cotton planting rows.

[0018] Preferably, the granular fertilizer application mechanism includes a fertilizer application turntable and a discharge pipe. The fertilizer application turntable is fixedly installed on the auxiliary drive shaft. Fertilizer application grooves are arranged in a ring array on the fertilizer application turntable. A discharge through hole is provided on the fertilizer storage box at the bottom of the fertilizer application turntable. During the rotation of the fertilizer application turntable, the granular fertilizer in the fertilizer groove is spread into the discharge pipe through the discharge through hole and falls into the fertilizer application gap through the discharge pipe.

[0019] Preferably, the upper part of the water and fertilizer tank is fitted with a sealing cover plate via a hinge. The water and fertilizer application mechanism includes a one-way air intake telescopic cylinder and an eccentric turntable. The one-way air intake telescopic cylinder is fixedly mounted on the sealing cover plate and extends outward. An air intake hole is provided on the outer side of the one-way air intake telescopic cylinder. The telescopic arm of the one-way air intake telescopic cylinder moves against the eccentric turntable. The eccentric turntable is fixedly mounted on the auxiliary drive shaft. The rotational motion of the eccentric turntable drives the telescopic arm of the one-way air intake telescopic cylinder to extend and retract, thereby pumping external gas into the water and fertilizer tank in one direction. The pressure inside the water and fertilizer tank increases, thereby pumping liquid fertilizer outward through the liquid fertilizer spray holes opened on the baffle and the top plate.

[0020] Preferably, the top plate is an arched arc plate, and the top plates on both sides are fixedly connected by a lifting plate. The lifting plate has an internal threaded hole, and a lifting screw is inserted into the internal threaded hole. The lifting screw is fixedly installed on the drive shaft of the lifting motor. The rotation of the lifting motor drives the top plate to move up and down and translate. The lifting motor is fixedly installed at the bottom of the fertilizer storage box.

[0021] Preferably, the baffles of the ridge fertilization mechanism are all fixedly installed at the bottom of the fertilizer storage box, and the liquid fertilizer spray holes on the baffles are arranged vertically. Height adjustment plates are also fixedly installed on both sides of the top plate. The height adjustment plates abut against the liquid fertilizer spray holes on the baffles. During the lifting and lowering process of the top plate, the opening height of the vertically arranged liquid fertilizer spray holes is adjusted, thereby adjusting the spraying height of the liquid fertilizer spray holes on the top plate.

[0022] Preferably, the rear ends of the vehicle frame are also equipped with soil-collecting plow plates via sliders.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention enables simultaneous cultivation and fertilization of two rows of cotton seedlings along a ridge, achieving higher efficiency than single-ridge cultivation and fertilization devices. It is equipped with liquid fertilizer and granular fertilizer application devices to meet the fertilization needs of different locations within and between ridges. Furthermore, the spraying range of the liquid fertilizer can be adjusted according to the growth height of the cotton seedlings at different stages. The cultivation and fertilization process is powered by a towing agricultural machine, simplifying the structure while improving the fertilization effect of the device. Attached Figure Description

[0032] 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.

[0033] Please see Figure 1-6 The present invention provides a technical solution:

[0034] Example 1:

[0035] A type of inter-row cultivation and fertilization machine suitable for cotton fields includes:

[0036] The frame 1 has wheel frames 2 fixedly and rotatably mounted on both sides of the front end of the frame 1. On the side of the wheel frames 2 away from the frame 1, a travel wheel 3 is mounted through a pivot.

[0037] The towing frame 4 is fixedly connected to the vehicle frame 1 and is connected to the pin shaft of the towing agricultural machinery, thereby driving the inter-tillage and fertilizer applicator to perform inter-tillage and fertilizer operations through the towing agricultural machinery.

[0038] Multiple inter-row cultivation and fertilization claws 5 are fixedly and equidistantly installed at the bottom of the frame 1. The inter-row cultivation and fertilization claws 5 are V-shaped, with the pointed end of the V-shaped inter-row cultivation and fertilization claws 5 facing the front of the vehicle body in the direction of travel. The two side plates of the inter-row cultivation and fertilization claws 5 are separated to form a fertilization gap 6.

[0039] The ridge fertilization mechanism is set between multiple ridge cultivation and fertilization claws 5. The ridge fertilization mechanism includes baffles 7 fixedly installed on the left and right sides and a top plate 8 that is lifted and set on the baffles 7 on both sides. Liquid fertilizer spray holes 9 are set on the opposite side of the baffles 7 and the bottom of the top plate 8. The cotton crop in the ridge is sprayed and fertilized through the liquid fertilizer spray holes 9.

[0040] Fertilizer storage box 10 is fixedly installed on the frame 1. Inside the fertilizer storage box 10, a water-fertilizer box 12 and a granular fertilizer box 13 are formed by partition 11. The water-fertilizer box 12 is equipped with a water-fertilizer application mechanism. The application pipe of the water-fertilizer application mechanism is connected to the liquid fertilizer spray hole 9 installed on the baffle 7 and the top plate 8. The granular fertilizer box 13 is equipped with a granular fertilizer application mechanism. The discharge pipe 14 of the granular fertilizer application mechanism extends to the outside of the fertilizer storage box 10 and is set above the application gap 6 of the V-shaped ridge cultivation fertilizer claw 5.

[0041] The transmission mechanism includes a main drive shaft 15 and a secondary drive shaft 16, which are connected by a transmission belt 17. The secondary drive shaft 16 is located inside the fertilizer storage box 10 and is connected to the water and fertilizer application mechanism and the granular fertilizer application mechanism. The main drive shaft 15 is connected to the transmission disc of the towing agricultural machinery via the transmission belt 17, and the rotation of the transmission disc provides power to the water and fertilizer application mechanism and the granular fertilizer application mechanism.

[0042] In this embodiment, the frame 1 serves as the main structure, with a travel wheel 3 mounted on its front end via a wheel frame 2. Hydraulic telescopic connecting rods 18 are also rotatably mounted on both sides of the front end of the frame 1. The end of the hydraulic telescopic connecting rod 18 furthest from the frame 1 is connected to a pivot on the wheel frame 2 via a pivot hole. The height of the frame 1 off the ground is adjusted by extending and retracting the hydraulic telescopic connecting rods 18, thereby adjusting the tillage depth of the device. The frame 1 and the travel wheel 3 move under the towing of a towing machine. The towing machine is fixedly connected to the frame 1 via a towing frame 4, which is connected to the towing machine using a pin connection—a common connection method in existing agricultural machinery. Multiple inter-row tillage and fertilization claws 5 are provided at the bottom of the frame 1. The system can be assembled according to the width of the cultivated rows, enabling simultaneous cultivation of at least two cotton seedling rows. The inter-row cultivation and fertilization claws 5 are V-shaped, serving both to break up the soil between the rows and to act as a ditching mechanism before fertilization. The two side plates of the inter-row cultivation and fertilization claws 5 separate to form a fertilization gap 6, allowing granular fertilizer to be buried below the soil level in the rows. Between the inter-row cultivation and fertilization claws 5 is a row fertilization mechanism for spraying liquid fertilizer onto the cotton seedling rows. This mechanism consists of baffles 7 and a top plate 8 that is raised and lowered on both sides of the baffles 7. The baffles 7 ensure that the cotton seedlings are not damaged during cultivation and also allow liquid fertilizer to be sprayed onto the seedlings through the liquid fertilizer spray holes 9 on their sides. The fertilizer spraying operation offers a more concentrated spraying range and improved accuracy compared to existing liquid fertilizer spraying mechanisms. To accommodate both granular and liquid fertilizers, a fertilizer storage tank 10 is fixedly installed on the frame 1. This tank is divided into a water-fertilizer tank 12 and a granular fertilizer tank 13 by a partition 11. The water-fertilizer tank 12 houses a water-fertilizer application mechanism, whose application pipe connects to the liquid fertilizer spray nozzles 9 installed on the baffle 7 and top plate 8. The granular fertilizer tank 13 houses a granular fertilizer application mechanism, whose discharge pipe 14 extends outward from the storage tank 10 and is positioned above the application gap 6 of the V-shaped ridge-inter-row cultivation fertilizer application claw 5, facilitating the smooth application of both granular and water-fertilizers. Note that... In actual farming, granular fertilizer can be applied only between rows, or liquid fertilizer can be applied separately during cotton seedling growth. Alternatively, both granular and liquid fertilizer can be applied simultaneously. Simply add fertilizer to the corresponding water-fertilizer tank 12 or granular fertilizer tank 13. The application process is achieved through a transmission mechanism, which includes a main drive shaft 15 and a secondary drive shaft 16. The main drive shaft 15 is connected to the drive disc of the towed agricultural machinery via a drive belt 17, and the secondary drive shaft 16 is connected to the water-fertilizer application mechanism and the granular fertilizer application mechanism to complete the fertilization operation. The significance of this setup is that there is no need to introduce a separate power structure; fertilization and cultivation can be carried out using the power provided by the towed agricultural machinery.

[0043] Example 2:

[0044] The main drive shaft 15 is movably inserted into the transmission frame 19, and the transmission frame 19 is fixedly installed on the towing frame 4. A transition drive shaft 20 is also provided between the main drive shaft 15 and the auxiliary drive shaft 16. The transition drive shaft 20 is connected to the main drive shaft 15 and the auxiliary drive shaft 16 through a transmission belt. The auxiliary drive shaft 16 is fixedly and rotatably located at the bottom of the fertilizer storage box 10.

[0045] In this embodiment, the main drive shaft 15 and the auxiliary drive shaft 16 further transmit power through the transition drive shaft 20 and the drive belt 17, thereby ensuring normal power output.

[0046] Example 3:

[0047] There are three inter-row cultivation and fertilization claws 5. The three inter-row cultivation and fertilization claws 5 are fixedly installed in the middle and on both sides of the frame 1. The gap between the three inter-row cultivation and fertilization claws 5 is located at the cotton planting ridge. There are two sets of ridge fertilization mechanisms, which are respectively set at the gap formed by the three inter-row cultivation and fertilization claws 5.

[0048] The fertilizer storage box 10 is equipped with four sets of partitions 11, which divide the inside of the fertilizer storage box 10 into three sets of granular fertilizer boxes 13 and two sets of water and fertilizer boxes 12. The three sets of granular fertilizer boxes 13 are set above the cotton planting ridges, and the two sets of water and fertilizer boxes 12 are set above the cotton planting rows.

[0049] In this embodiment, three inter-row cultivation and fertilization claws 5 are further disclosed, corresponding to two sets of ridge fertilization mechanisms. This allows the device to simultaneously perform inter-row cultivation and fertilization operations on two cotton seedling ridges. The inter-row cultivation and fertilization claws 5 have a V-shaped structure and need to penetrate to a certain depth below the soil during cultivation. This process is achieved by adjusting the extension length of the hydraulic telescopic connecting rod 18. Since it is not necessary to turn over the soil in the ridges during the cultivation process in cotton fields, as large-scale turning may damage the roots and stems of cotton seedlings, the V-shaped inter-row cultivation and fertilization claws 5 can achieve cultivation operations such as breaking and turning the soil. In addition, a rotary tillage mechanism with better soil turning effect can also be installed at this position, and corresponding adjustments can be made later.

[0050] Example 4:

[0051] The granular fertilizer application mechanism includes a fertilizer application turntable 21 and a discharge pipe 14. The fertilizer application turntable 21 is fixedly installed on the auxiliary drive shaft 16. Fertilizer application troughs 22 are arranged in a ring array on the fertilizer application turntable 21. The fertilizer storage box 10 at the bottom of the fertilizer application turntable 21 has a through-hole for discharging. During the rotation of the fertilizer application turntable 21, the granular fertilizer in the fertilizer application trough 22 is spread into the discharge pipe 14 through the discharge hole and falls into the fertilizer application gap 6 through the discharge pipe 14.

[0052] A sealing cover plate 23 is installed on the upper part of the water and fertilizer tank 12 via a hinge. The water and fertilizer application mechanism includes a one-way air intake telescopic cylinder 24 and an eccentric turntable 25. The one-way air intake telescopic cylinder 24 is fixedly installed on the sealing cover plate 23 and extends outward. An air intake hole is opened on the outer side of the one-way air intake telescopic cylinder 24. The telescopic arm of the one-way air intake telescopic cylinder 24 moves against the eccentric turntable 25. The eccentric turntable 25 is fixedly installed on the auxiliary drive shaft 16. The rotation of the eccentric turntable 25 drives the telescopic arm of the one-way air intake telescopic cylinder 24 to extend and retract, thereby pumping external gas into the water and fertilizer tank 12 in one direction. The pressure inside the water and fertilizer tank 12 increases, thereby pumping liquid fertilizer outward through the liquid fertilizer spray holes 9 opened on the baffle 7 and the top plate 8.

[0053] In this embodiment, the specific structures of the granular fertilizer application mechanism and the water-fertilizer application mechanism are further disclosed. Both the fertilizer application turntable 21 and the eccentric turntable 25 are fixedly mounted on the auxiliary drive shaft 16. Multiple sets of fertilizer application turntables 21 and eccentric turntables 25 can be driven by a single auxiliary drive shaft 16. (Refer to the appendix of the instruction manual.) Figure 4-5 The fertilization turntable 21 rotates to deliver the granular fertilizer that has entered the fertilization trough 22 into the discharge pipe 14, and finally falls into the fertilization gap 6. The eccentric turntable 25 rotates to drive the telescopic arm of the one-way air intake telescopic cylinder 24 to reciprocate. The structure of the one-way air intake telescopic cylinder 24 is similar to that of a daily air pump, mainly composed of a built-in piston rod and a one-way air intake valve. During each stroke of the eccentric turntable 25, the telescopic arm of the one-way air intake telescopic cylinder 24 closely abuts against the surface of the eccentric turntable 25 under the action of the built-in compression spring, so that the telescopic arm of the one-way air intake telescopic cylinder 24 can perform reciprocating lifting and lowering movements, so that gas enters the water and fertilizer tank 12 unidirectionally through the air inlet set above the one-way air intake telescopic cylinder 24. The pressure inside the water and fertilizer tank 12 increases, thereby pumping the liquid fertilizer out through the liquid fertilizer spray hole 9 opened on the baffle 7 and the top plate 8, thus completing the fertilization operation.

[0054] Example 5:

[0055] The top plate 8 is an arched plate. The top plates 8 on both sides are fixedly connected by a lifting plate 26. The lifting plate 26 has an internal threaded hole, and a lifting screw 27 is inserted into the internal threaded hole. The lifting screw 27 is fixedly installed on the drive shaft of the lifting motor 28. The rotation of the lifting motor 28 drives the top plate 8 to move up and down. The lifting motor 28 is fixedly installed at the bottom of the fertilizer storage box 10.

[0056] In this embodiment, the lifting drive mechanism of the two top plates 8 is further disclosed. The rotation of the lifting motor 28 drives the lifting screw 27 to rotate, thereby causing the lifting plate 26 to drive the two top plates 8 to move up and down synchronously. In the same cotton planting field, the cotton is sown at the same time and its growth status is similar. Therefore, the plant height is relatively uniform at the same time. During the inter-tillage process, the tiller only needs to adjust the height of the top plate 8 according to the general growth status of the cotton in the same cotton planting field, so that it can be adjusted in a targeted manner according to the growth status of the cotton, thereby ensuring more concentrated spraying. This height adjustment process is achieved by controlling the forward and reverse movement of the lifting motor 28. A button for controlling the forward and reverse movement of the lifting motor 28 is provided on the vehicle body 1, so that the operator can make adjustments independently.

[0057] Example 6:

[0058] The baffles 7 of the row fertilization mechanism are all fixedly installed at the bottom of the fertilizer storage box 10. The liquid fertilizer spray holes 9 opened on the baffles 7 are arranged vertically. Height adjustment plates 29 are also fixedly installed on both sides of the top plate 8. The height adjustment plates 29 abut against the liquid fertilizer spray holes 9 opened on the baffles 7. During the lifting and lowering process, the opening height of the vertically arranged liquid fertilizer spray holes 9 is adjusted, thereby adjusting the spraying height of the liquid fertilizer spray holes 9 set on the top plate 8.

[0059] In this embodiment, height adjustment plates 29 are also fixedly installed on both sides of the baffle 7. The top plate 8 abuts against the baffles 7 on both sides during the lifting and lowering process. When the top plate 8 is at its lowest position, the height adjustment plates 29 block all the liquid fertilizer spray holes 9 on the baffle 7. At this time, the liquid fertilizer can only be sprayed downward through the liquid fertilizer spray holes 9 opened on the top plate 8. When the top plate 8 rises, the liquid fertilizer spray holes 9 on the baffle 7 are opened one by one. The significance of this setting is that, since cotton seedlings need to be cultivated multiple times, and the height of cotton seedlings is different at different cultivation stages, by adjusting the height of the top plate 8, it can be ensured that the cotton seedlings are not damaged during cultivation. At the same time, it can also be more precise to spray liquid fertilizer, ensuring that the liquid fertilizer can act on the top and around the cotton seedlings, thereby ensuring comprehensive fertilization.

[0060] Example 7:

[0061] At both ends of the rear of the frame 1, soil-collecting plow plates 31 are installed via sliders 30. The soil is turned over by the soil-collecting plow plates 31. In addition, a soil-rotating wheel can be added to the frame 1 to further optimize the tillage effect. All of these are within the scope of protection of this invention.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
