Description

Technical Field

[0001] This invention mainly relates to the field of coupled fertilization technology, specifically to a method and equipment for coupled fertilization of organic materials and microbial agents. Background Technology

[0002] my country has a vast land area, but in some areas with harsh environments, direct planting of agricultural products is not feasible, such as saline-alkali land. Saline-alkali soil has low organic content, making it difficult for plants to survive. Therefore, soil conditioning is necessary for saline-alkali land. Soil conditioning requires adding organic materials and microbial agents to the soil for fertilization, thereby continuously adjusting the soil structure and stability. Currently, many technologies involve manual fertilization, while some are integrated water and fertilizer machines. However, integrated water and fertilizer machines require powerful irrigation systems, resulting in high costs and complex installation. There are also fertilizer applicators, which require loading fertilizer into the machine's hopper before discharging it. Fertilizer applicators can only add one type of fertilizer at a time, and the addition can only be done by directly discharging it using a spiral roller, making it impossible to control the amount. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] In view of the above-mentioned problems, the present invention provides a method and equipment for coupled fertilization of organic materials and microbial agents, which can apply multiple different organic fertilizers to the soil at one time and control the application amount.

[0005] (II) Technical Solution

[0006] To address the aforementioned technical problems, this invention provides a coupled fertilization device for organic materials and microbial agents, comprising a trolley with an open annular outer shell mounted on top. An annular conveyor belt is located at the bottom of the open annular outer shell. A large support frame is welded inside the annular ring of the outer shell. A screen is fixedly mounted on the side of the large support frame, and a water spraying device with multiple nozzles is positioned above the screen. A central rotating rod is rotatably connected to one side of the large support frame, and a gripping rod is slidably connected to the central rotating rod. The gripping rod has a grab bucket. The large support frame also has a shaped groove, and the gripping rod is slidably mounted within the shaped groove. A rotating rod is rotatably mounted on the large support frame, and a transmission rod is rotatably mounted on the other side of the large support frame. The transmission rod is perpendicular to the rotating rod and connected to the rotating rod by a 90-degree turning rod. A cover-opening assembly is arranged parallel to the transmission rod, and the cover-opening assembly is connected to the transmission rod using a belt drive principle. The gripping rod is slidably connected to a small slider, and a cam is fixedly mounted on the small slider. The cam engages with the cover-opening assembly.

[0007] Furthermore, a cylindrical rod is fixedly installed on the grabbing rod, and the cylindrical rod passes through the groove of the intermediate rotating rod and is slidably connected in the irregular groove; the grab bucket is located at the end away from the cylindrical rod.

[0008] Furthermore, the intermediate rotating rod is fixedly mounted on the rotating rod, which is set through the large bracket and is driven by the power assembly.

[0009] Furthermore, the grab bucket includes a bucket cylinder, one end of which is fixedly installed at the end of the grabbing rod. The movable end of the bucket cylinder is fixedly connected to the bucket cylinder. An upper bucket and a lower bucket are rotatably mounted on the bucket cylinder. The upper bucket has two first long slots, each containing an upper connecting rod. One end of the upper connecting rod is rotatably connected to the inside of the upper bucket, and the other end is rotatably connected to the grabbing rod. The lower bucket has two second long slots, each containing a lower connecting rod. One end of the two lower connecting rods is rotatably connected to the inside of the lower bucket, and the other end is rotatably connected to the grabbing rod.

[0010] Furthermore, the irregularly shaped slide is divided into three parts: the first part is an annular shape, the second part is a vertical section, and the third part is a horizontal section. The second and third parts are perpendicular to each other and close to each other, with a gap between the second and third parts; the pivot point of the middle rotating rod is at the center of the irregularly shaped slide.

[0011] Furthermore, the transmission rod includes a reversing rod, which is arranged parallel to the direction of gravity. One end of the reversing rod is slidably connected to a 90-degree steering rod, and the other end of the reversing rod is fixedly connected to a first pulley. A pull rope is provided between the first pulley and the cover opening assembly, and the pull rope is wrapped in a figure-eight shape.

[0012] Furthermore, the opening assembly includes an opening rod, which is arranged parallel to the reversing rod. A second pulley is fixedly installed on the opening rod, and a pull rope is provided between the second pulley and the first pulley. The opening rod is rotatably connected to a pull ring, and a tension spring is provided at each end of the pull ring. The two tension springs are respectively connected to the large bracket. A cam engagement is formed between the cam and the opening rod.

[0013] Furthermore, an electromagnet block is fixedly installed on the cover-opening rod and below the second pulley.

[0014] A method for coupled fertilization of organic materials and microbial agents, using the aforementioned coupled fertilization equipment, includes the following steps:

[0015] Step 1: Move the trolley to the location where fertilization is needed, place different types of fertilizer buckets on the circular outer shell, and transport them by the circular conveyor belt to the area below the electromagnet block.

[0016] Step 2: Activate the electromagnet block to attract the fertilizer iron cover, then activate the power unit to drive the central rotating rod to rotate. The central rotating rod drives the gripping rod to slide, and the gripping rod drives the small slider to rotate, thereby causing the cam to release the pressure on the opening rod. Under the action of the tension spring, the opening rod will lift the fertilizer iron cover to achieve opening.

[0017] Step 3: When the middle rotating rod rotates, it drives the rotating rod to rotate. Under the action of the 90-degree turning rod, it drives the transmission rod to rotate. Under the action of the pull rope, it drives the opening rod to rotate. The electromagnet block will rotate the fertilizer iron cover to make room for grabbing the fertilizer.

[0018] Step 4: While opening the fertilizer iron lid, the grabbing rod with the grab bucket grabs fertilizer from inside the fertilizer barrel. Then, the power unit is activated to reverse the direction. The fertilizer iron lid will cover the fertilizer barrel, and the grabbing rod with the grab bucket will move horizontally to send the grabbed fertilizer to the sieve.

[0019] Step 5: Start the grab bucket, pour out the fertilizer, sieve it through the screen, and then start the water spraying device to irrigate the soil. While cleaning the grab bucket, irrigate the plants on the land.

[0020] The advantages of this invention compared to existing technologies are as follows: 1. This invention includes a trolley, a circular outer shell, a circular conveyor belt, a large support frame, a sieve, and a water spraying device. This allows the fermented fertilizer buckets to be used directly without needing to be removed and refilled. It can also transport multiple fertilizer buckets at once, enabling the application of various fertilizers to the soil simultaneously and the mixing of different fertilizers. 2. The grab bucket of this invention can open and close automatically. Once the fertilizer bucket reaches the designated position, one or two buckets of fertilizer can be added as needed. 1. Add one or two buckets of other fertilizers, with the amount of fertilizer extracted from each bucket within a controllable range, thereby controlling the amount of fertilizer applied and allowing for the mixing of multiple fertilizers; 2. The mechanism composed of the opening assembly, transmission rod, 90-degree turning rod, irregular slide, intermediate rotating rod, gripping rod, small slider, and cam of this invention enables the opening and material extraction steps to be carried out sequentially and orderly, with a more compact structure and function, achieving automatic fertilization; 3. The method of this invention can automatically apply fertilizer, can mix fertilizers, and can achieve controllable fertilizer application, providing support for improving the environment of saline-alkali land.

[0031] A transmission rod is rotatably mounted on the other side of the large support 107. The transmission rod is perpendicular to the rotating rod 117 and is connected to the rotating rod 117 by a 90-degree turning rod 118. The transmission rod includes a reversing rod 119, which is parallel to the direction of gravity. The reversing rod 119 passes through two second connecting seats 129 and is rotatably mounted on the two second connecting seats 129. The two second connecting seats 129 are arranged vertically and are fixedly mounted on the large support 107. One end of the reversing rod 119 is slidably connected to the 90-degree turning rod 118, and the other end of the reversing rod 119 is fixedly connected to a first pulley 120. A pull rope 121 is provided between the first pulley 120 and the cover opening assembly. The pull rope 121 is wrapped in a figure-eight shape. The rotating rod 117 and the reversing rod 119 are in two perpendicular directions.

[0032] A cylindrical rod is fixedly installed on the gripping rod 108. The cylindrical rod passes through the groove of the intermediate rotating rod 109 and is slidably connected in the irregular groove 110. The grab bucket is located at the end away from the cylindrical rod. The intermediate rotating rod 109 is fixedly connected to the rotating rod 117. The rotating rod 117 is set through the large bracket 107. The rotating rod 117 is driven by a power component, which includes a power motor 116. The power motor 116 is fixedly installed on the large bracket 107 with fasteners. The output shaft of the power motor 116 passes through the large bracket 107, and a small pulley 112 is fixedly installed on the end on the same side as the intermediate rotating rod 109. Another small pulley 112 is fixedly installed on the rotating rod 117. A small belt 111 is sleeved on the two small pulleys 112, and a belt drive is formed between the two small pulleys 112 and the small belt 111.

[0033] The grab bucket includes a bucket cylinder 135, one end of which is fixedly installed at the end of the grabbing rod 108. The movable end of the bucket cylinder 135 is fixedly connected to the bucket cylinder 132. An upper bucket 131 and a lower bucket 133 are rotatably mounted on the bucket cylinder 132. The upper bucket 131 has two first long slots, each containing an upper connecting rod 130.

One end of the two lower connecting rods 134 is rotatably connected to the inside of the lower bucket 133, and the other end is rotatably connected to the grabbing rod 108.

[0034] The irregular-shaped slide 110 is divided into three parts: the first part is circular, the second part is a vertical section, and the third part is a horizontal section. The second part and the third part are perpendicular to each other and close to each other, and there is a gap between the second part and the third part; the pivot point of the middle rotating rod 109 is at the center of the irregular-shaped slide 110.

[0035] The cover opening assembly includes a cover opening rod 124, which is rotatably and slidably mounted on a first connecting seat 125. The first connecting seat 125 is fixedly mounted on a large bracket 107. The cover opening rod 124 is arranged parallel to the reversing rod 119. A second pulley 122 is fixedly mounted on the cover opening rod 124. A pull rope 121 is provided between the second pulley 122 and the first pulley 120. The pull rope 121 is a circular cross-section rope to reduce the friction caused by the rising of the second pulley 122. 121 is wrapped in a figure-eight shape around the second pulley 122 and the first pulley 120. The opening rod 124 is rotatably connected to the pull ring 126. Each end of the pull ring 126 is provided with a tension spring 127, and the two tension springs 127 are respectively connected to the large bracket 107. The gripping rod 108 is slidably connected to the small slider 115. The small slider 115 is rotatably mounted on the large bracket 107. A cam 128 is fixedly mounted on the small slider 115, and a cam engagement is formed between the cam 128 and the opening rod 124.

[0036] An electromagnet block 123 is also fixedly installed on the cover opening rod 124 and below the second pulley 122.

[0037] The working principle of this invention is as follows: First, the trolley 101 is moved to a place where fertilization or soil improvement is needed, such as saline-alkali land. Then, depending on the local soil environment, the amount of fertilizer to be added is determined. Fertilizers can be in various forms, such as straw, cow manure, and biochar. Different amounts and types of fertilizers are added to saline-alkali land according to the situation to improve the soil and irrigate local plants.

[0038] Fertilizer buckets 103 containing different fertilizers are placed on a circular conveyor belt 106. The circular conveyor belt 106 is started to transport the fertilizer buckets 103 sequentially to the area below the electromagnet block 123. Then, a grab bucket is used to grab one or two buckets of fertilizer each time and spread them on the saline-alkali land. Each type of fertilizer is spread in a fixed quantity to control the amount and ratio of fertilizer. When the fertilizer bucket 103 of a certain type of fertilizer reaches the area below the electromagnet block 123, the electromagnet block 123 is started to hold the fertilizer iron cover 104, and then the power motor 116 is started.

[0039] After the power motor 116 starts, it will drive the intermediate rotating rod 109 and the rotating rod 117 to rotate under the action of the small pulley 112 and the small belt 111. When the intermediate rotating rod 109 rotates, it will drive the gripping rod 108 to rotate. Figure 2 As shown, the central rotating rod 109 first rotates counterclockwise. When the gripping rod 108 rotates, it slides inside the small slider 115 and can rotate the small slider 115 at the same time. The rotation of the small slider 115 causes the cam 128 to rotate. The cam 128 changes from lifting stroke to falling stroke. The pull ring 126 will rise under the action of the tension spring 127. The pull ring 126 will also lift the cover opening rod 124 and the electromagnet block 123 to open the cover.

[0040] Rotating rod 117 rotates, and under the action of 90-degree turning rod 118, it drives reversing rod 119 to rotate. At this time, first pulley 120 will drive second pulley 122 to rotate under the action of pull rope 121. Second pulley 122 drives opening rod 124 to rotate. Opening rod 124 rotates, which will cause electromagnet block 123 to drive fertilizer iron cover 104 to rotate, rotating fertilizer iron cover 104 from above fertilizer barrel 103 to one side to make room for grab bucket operation.

[0041] As the grabbing rod 108 rotates, it gradually becomes vertical, and the grabbing rod 108, along with the grab bucket, enters the fertilizer bin 103. The movable end of the bucket cylinder 135 is extended, and under the action of the upper connecting rod 130 and the lower connecting rod 134, the upper bucket 131 and the lower bucket 133 are opened respectively. Then, the movable end of the bucket cylinder 135 is retracted to grab a bucket of fertilizer. At this time, the power motor 116 is started to reverse, and the middle rotating rod 109 will rotate clockwise. At this time, the cam 128 will press the cover rod 124 again, and the electromagnet block 123 will release the fertilizer iron cover 104. The fertilizer iron cover 104 will then be placed back on the fertilizer bin 103.

[0042] The fertilizer in fertilizer bin 103 is not emptied all at once, because it needs to be mixed and added each time, thus ensuring that a certain amount of fertilizer is grabbed by the grab bucket each time.

[0043] The grabbing rod 108 carries the fertilizer to the sieve 114. The movable end of the bucket cylinder 135 is activated and extends, opening the upper bucket 131 and the lower bucket 133 to throw out the fertilizer. After being sieved by the sieve 114, the fertilizer becomes finer and more uniform, ensuring that the soil is fertilized evenly and preventing the fertilizer from clumping together unevenly.

[0044] After spreading the fertilizer, the water spraying device 113 can be activated to spray water and irrigate in small amounts, while also cleaning the grab bucket. In this way, each type of fertilizer can be measured out by grabbing one or two buckets, and then the next type of fertilizer can be used, and the same amount of bucket can be grabbed again. Each bucket of fertilizer is sufficient for use. If there is not enough fertilizer in the bucket for the grab bucket to grab, it can be added manually in time. Because the treatment of saline-alkali land is carried out in sections and blocks, each bucket can guarantee the amount used each time.

[0045] Example 2: A method for coupled fertilization of organic materials and microbial agents, using the above-described coupled fertilization equipment for organic materials and microbial agents, including the following steps:

[0046] Step 1: Move the trolley 101 to the location where fertilization is needed, place different types of fertilizer buckets 103 on the annular outer shell 102, and transport them by the annular conveyor belt 106 to transport the different types of fertilizer buckets 103 to the area below the electromagnet block 123.

[0047] Step 2: Activate the electromagnet block 123 to hold the fertilizer iron cover 104 in place, then start the power motor 116 to drive the intermediate rotating rod 109 to rotate. Figure 2 As shown, the intermediate rotating rod 109 will rotate counterclockwise, and the intermediate rotating rod 109 will drive the gripping rod 108 to slide. While the gripping rod 108 slides on the small slider 115, it will drive the small slider 115 to rotate. The small slider 115 will drive the cam 128 to rotate, thereby causing the cam 128 to release the pressure on the opening rod 124. The tension spring 127 will rebound and reset. Under the action of the tension spring 127, the opening rod 124 will rise with the fertilizer iron cover 104 to open the cover.

[0048] Step 3: When the middle rotating rod 109 rotates, it also drives the rotating rod 117 to rotate. Under the action of the 90-degree turning rod 118, it drives the reversing rod 119 and the first pulley 120 to rotate. Under the action of the pull rope 121, it drives the second pulley 122 to rotate. The second pulley 122 drives the opening rod 124 to rotate. At this time, the electromagnet block 123 will drive the fertilizer iron cover 104 to rotate, making room for grabbing the fertilizer.

[0049] Step 4: While opening the fertilizer iron cover 104, the grabbing rod 108 grabs the fertilizer in the fertilizer bucket 103 with the grab bucket. Then, the power motor 116 is started to reverse, the fertilizer iron cover 104 will cover the fertilizer bucket 103, and the grabbing rod 108 will move horizontally with the grab bucket to send the grabbed fertilizer to the sieve 114.

[0050] Step 5: Start the bucket cylinder 135 of the grab bucket, which rotates and opens the upper bucket 131 and the lower bucket 133 to pour out the fertilizer. The fertilizer is then sieved through the screen 114. At the same time, the water spraying device 113 is started to spray water to clean the grab bucket and irrigate the plants on the land.

[0051] Any aspects not covered in this invention are applicable to existing technologies.
