Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, and in particular to a nutrient preparation device and method for restoring degraded grassland. Background Art

[0002] Grassland degradation is a global environmental problem, especially in arid and semi-arid areas. Grassland degradation is usually caused by a variety of natural and human factors such as overgrazing, climate change, soil erosion, salinization, etc. These factors reduce grassland vegetation coverage, reduce soil fertility, and lose biodiversity, which in turn affects the stability and service functions of grassland ecosystems. In the prior art, nutrients used for grassland restoration are generally composed of various fertilizer raw materials and water.

[0003] Existing nutrient preparation devices for grassland restoration are generally composed of a material dividing device and a stirring device. In the stirring device, a stirring rod is usually directly installed on the output shaft of the driving member. This method can effectively proportion and mix various raw materials to prepare nutrients for grassland restoration. Due to the large area of ​​grassland, more nutrients are required, resulting in a very large preparation amount each time. This results in the existing device requiring multiple driving members to drive multiple groups of stirring rods to increase the stirring amount and achieve the preparation of a large amount of nutrients, which greatly increases the preparation cost of nutrients.

[0004] In summary, how to solve the problem that the nutrient preparation device for grassland restoration in the prior art requires multiple driving parts to drive multiple groups of stirring rods to increase the stirring amount and achieve the preparation of a large amount of nutrients, which greatly increases the preparation cost of nutrients has become a difficult problem that needs to be solved in the current field. Therefore, it is necessary to propose a nutrient preparation device and method for degraded grassland restoration that can reduce mechanical wear. Summary of the invention

[0005] To solve the above problems, the present invention provides a nutrient preparation device and method for degraded grassland restoration. Through the design of the stirring component, multiple groups of stirring rods can be driven to rotate together through only a single driving part, so that the stirring range and stirring amount are greatly improved, thereby improving the utilization rate of raw materials and effectively reducing the preparation cost of nutrients.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a nutrient preparation device for restoring degraded grassland, comprising a distribution box, a mixing box and several raw material boxes, the bottoms of the raw material boxes are fixedly connected to the top of the distribution box, a feeding trough is opened at the bottom of the distribution box, the bottom of the feeding trough is connected to the top of the mixing box, and a feeding valve is fixedly connected at the connection point.

[0007] A stirring assembly for stirring raw materials and a material taking assembly for obtaining materials are arranged in the stirring box; a material dividing assembly for quantitatively distributing raw materials is arranged in the dividing box.

[0008] The stirring assembly includes a controller, a center rod and a plurality of supporting rods. The bottom of the center rod is fixedly connected to the bottom wall of the stirring box, the top of the center rod is fixedly connected to a driving member for generating stirring power, the output shaft of the driving member is coaxially fixedly connected to a connecting rod, and a slider is hinged on the end of the connecting rod away from the driving member; the slider is slidably matched with a sliding ring, the side of the sliding ring away from the connecting rod is fixedly connected to a rack, the side of the rack away from the sliding ring is slidably matched with a limit plate, and the side of the limit plate away from the rack is fixedly connected to the support rod adjacent to it.

[0009] The bottoms of the support rods are fixedly connected to the bottom wall of the mixing box and are symmetrically distributed on both sides of the center rod; the upper side walls of the support rods are rotatably connected to gears, and the gears are meshed with racks; a number of stirring rods are fixedly connected to the side of the gear away from the sliding ring; the controller is used to control the operation of the drive and the feeding valve.

[0010] The technical principles of the above scheme are as follows:

[0011] First, various types of raw materials are placed in various raw material boxes respectively. After the raw materials are placed, the required amount of each raw material is input through the controller, and the material distribution component is started, so that each raw material is placed into the feeding trough according to the required amount.

[0012] After all the raw materials are put into the feeding trough according to the required amount, the controller opens the feeding valve, and all the raw materials fall into the mixing box; at this time, the controller starts the driving part, and the output shaft of the driving part drives the connecting rod to rotate. Since the connecting rod and the slider are hinged, and the slider and the sliding ring are slidingly matched, when the connecting rod rotates, it will drive the slider to rotate. At the same time, the slider will also slide in the sliding ring and generate thrust on the sliding ring; and since the sliding ring is fixedly connected to the rack, and the rack and the limit plate are slidingly matched, the thrust generated by the rotation of the slider will push the sliding ring and the rack to slide along the length direction of the limit plate. Since the rack and the gear are meshed with each other, all the gears will rotate, thereby driving multiple sets of stirring rods to rotate, so as to achieve large-scale stirring and mixing of the raw materials.

[0013] The above scheme has the following beneficial effects:

[0014] 1. The present invention adopts a combined structure of connecting rods, sliders, sliding rings, racks and gears, and realizes the synchronous rotation of multiple driving parts and multiple groups of stirring rods through a single power source of the driving part, thereby increasing the stirring range, increasing the mixing volume, and improving the principle utilization rate and the uniformity and efficiency of raw material mixing. The operation of the entire device is completed through the controller. The user only needs to input the required amount of raw materials and the start command to automatically complete the distribution, stirring and mixing of the raw materials. The operation is simple and easy.

[0015] 2. The arrangement of the material distribution assembly in the present invention ensures that each raw material is accurately distributed to the feed trough according to the required amount, avoiding the problem of raw material waste and inaccurate proportions, and helping to obtain a nutrient formula that meets the requirements.

[0016] 3. In the present invention, the support rods are symmetrically distributed on both sides of the central rod, which not only provides a stable support structure, but also enables the stirring rods to be evenly distributed in the stirring box, further improving the stirring effect.

[0017] Furthermore, the material dividing assembly includes a plurality of material dividing shells, the tops of the material dividing shells are respectively connected to the bottoms of the raw material boxes adjacent thereto, and the bottoms of the material dividing shells are connected to the feeding troughs; a material dividing block is rotatably fitted inside the material dividing shells, and a plurality of receiving grooves are provided on the material dividing blocks; a weight sensor is fixedly connected to the bottom wall of the receiving groove, and a control valve is fixedly connected to the side of the receiving groove close to the material dividing shell; a rotating part for rotating the material dividing block is fixedly connected to the inner wall of the material dividing shell, and the output shaft of the rotating part is coaxially fixedly connected to the material dividing block; a controller is used to control the operation of the rotating part and receive signals from the weight sensor; a sealing layer is fixedly connected between the inner wall of the material dividing shell and the rotating gap of the material dividing block.

[0018] Beneficial effect: After the raw materials are put in, the required amount of each raw material is input through the controller, and the control valve is opened through the controller, so that each raw material flows into the receiving trough through the control valve. When the weight sensor detects that the weight of the raw materials in the receiving trough has reached the required amount, the controller will close the control valve and start the rotating part at the same time; at this time, the output shaft of the rotating part will drive the dividing block to rotate 180°, aligning the receiving trough containing the raw materials with the feeding trough, and then the controller will open the control valve to discharge the raw materials into the feeding trough.

[0019] Since the volumes of the receiving tanks are the same, the amounts of raw materials they can accommodate are also the same, and the maximum storage weights of the same raw materials are also the same; if the required amount of raw material weight is greater than the maximum storage weight, when the weight sensor detects that the weight of the raw material in the receiving tank has reached the maximum storage weight, the controller will close the control valve and start the rotating part at the same time; at this time, the output shaft of the rotating part will drive the material dividing block to rotate 90°, aligning the receiving tanks that are not filled with raw materials with the raw material box in turn, and opening the control valves in turn until the total amount of this type of raw material delivered reaches the required amount, at which time the controller will close all control valves and stop the delivery of this type of raw material.

[0020] In this process, the sealing layer can effectively prevent the slag from entering the rotation gap between the inner wall of the dividing shell and the dividing block, thereby affecting the rotation of the dividing block and the dividing shell.

[0021] Furthermore, the material taking component includes a material taking pump, which is fixedly connected to the lower side wall of the mixing box, and the controller is used to control the operation of the material taking pump.

[0022] Beneficial effect: After the raw materials are stirred and mixed, the required nutrients are obtained; when the materials need to be taken for use, only the required weight of the nutrients needs to be input through the controller, and the controller will turn on the material pump and discharge the corresponding weight of the nutrients.

[0023] Furthermore, scrapers are fixedly connected to both sides of the rack, and the scrapers are slidably matched with the upper and lower inner walls of the mixing box.

[0024] Beneficial effect: When the rack slides left and right, it will also slide left and right with the scrapers on both sides; the scrapers will scrape the raw materials on both sides of the stirring rod and push them to the stirring rod, making the stirring of the raw materials more uniform and comprehensive.

[0025] Furthermore, a protection box for protecting the operation of the gear and the rack is fixedly connected to the bottom wall of the mixing box, the limit plate passes through the protection box and is fixedly connected to the protection box, and the rack is slidably matched with the protection box.

[0026] Beneficial effects: The protective box can provide independent operating space for gears and racks, greatly reducing the problem of gear and rack jamming due to excessive raw materials. It also prevents raw materials and water from entering the driving parts and rotating parts, affecting the operation of the driving parts and rotating parts; thereby ensuring the normal operation of the entire device.

[0027] Furthermore, a gravity sensor is embedded in the bottom wall of the mixing box, and the controller is used to receive a signal from the gravity sensor.

[0028] Beneficial effects: During the entire configuration process, the gravity sensor can detect the total weight of the raw materials; after the configuration is completed, the gravity sensor can detect the total weight of the finished nutrient products; it is convenient for users to judge the weight of the required nutrients and whether the subsequent material collection amount is sufficient.

[0029] Furthermore, a top cover is detachably connected to the top of the raw material box.

[0030] Beneficial effects: When the raw materials are put in, the top cover can be opened to facilitate the feeding; after the feeding is completed, the top cover is closed to prevent foreign impurities from entering the device, thereby ensuring the operating stability of the device and protecting the quality of the finished nutrient product.

[0031] Furthermore, the feeding trough is arranged in a conical shape.

[0032] Beneficial effects: The tapered feeding trough makes the feeding port larger and the storage space larger, so that more raw materials can be transported and stored. Due to the tapered structure, the side wall of the feeding trough has a certain slope, so that the raw materials will slide to the bottom of the feeding trough, thereby facilitating the transmission of the raw materials.

[0033] Furthermore, one end of the stirring rod away from the gear is fixedly connected with an elastic brush.

[0034] Beneficial effects: During the mixing process, some raw materials will adhere to the scraper and the side wall of the mixing box; the brush can effectively clean and scrape the raw materials attached to the scraper and the side wall of the mixing box, thereby improving the utilization rate of the raw materials; at the same time, it also reduces the weight of the scraper and the mixing box, reducing the burden on the device.

[0035] Furthermore, a method for preparing nutrients for restoring degraded grasslands comprises the following steps:

[0036] S1, raw material placement: determine the required raw materials according to the condition of the grassland to be restored; and place the raw materials into each raw material box respectively.

[0037] S2, raw material distribution: after the raw materials are put in, according to the proportion of each raw material in the required nutrients, the distribution valve corresponding to each raw material box is opened, the rotating parts are started, and each raw material is transported to the mixing box, and the output weight of each raw material is monitored at the same time.

[0038] S3, raw material mixing: after the raw material transportation is completed, the driving part is started to stir and mix the raw materials.

[0039] S4, finished product extraction: open the extraction pump, obtain the specified amount of nutrients, and then use it.

[0040] Beneficial effects: The present invention can accurately control the amount and ratio of each raw material through the design of the material dividing shell and the material dividing block, ensuring the accuracy and effectiveness of the nutrient configuration process. At the same time, it improves the mixing efficiency and uniformity of the raw materials and greatly improves the quality of the finished nutrient products.

[0041] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The following is further described in detail through specific implementation methods:

[0051] Embodiment 1:

[0052] As attached Figure 1-Figure 6 As shown, a nutrient preparation device for degraded grassland restoration includes a distribution box 1, a mixing box 3 and a plurality of raw material boxes 2. The bottom of the raw material box 2 is bolted and connected to the top of the distribution box 1. A feeding trough is opened at the bottom of the distribution box 1. The bottom of the feeding trough is connected to the top of the mixing box 3. A feeding valve is bolted and connected at the connection point.

[0053] The mixing box 3 is provided with a mixing component for mixing raw materials and a material taking component for obtaining materials; the material dividing box 1 is provided with a material dividing component for quantitatively distributing raw materials.

[0054] like Figure 3 and Figure 4 As shown, the stirring assembly includes a controller, a center rod 4 and a plurality of support rods 401. The bottom of the center rod 4 is bolted fixedly connected to the bottom wall of the stirring box 3, and the top of the center rod 4 is bolted fixedly connected to a driving member for generating stirring power. In this embodiment, the driving member is a motor 5. The output shaft of the motor 5 is coaxially bolted fixedly connected to a connecting rod 6, and the connecting rod 6 is hinged with a slider 7 at one end away from the motor 5; the slider 7 is slidably matched with a sliding ring 8, and the sliding ring 8 is bolted fixedly connected with a rack 9 on the side away from the connecting rod 6, and the rack 9 is slidably matched with a limiting plate 12 on the side away from the sliding ring 8, and the limiting plate 12 is bolted fixedly connected to the support rod 401 adjacent to it on the side away from the rack 9.

[0055] The bottom of the support rod 401 is bolted to the bottom wall of the mixing box 3 and is symmetrically distributed on both sides of the center rod 4; the upper side walls of the support rod 401 are rotatably connected to the gear 10, and the gear 10 is meshed with the rack 9; the side of the gear 10 away from the sliding ring 8 is bolted to a plurality of stirring rods 11; the controller is used to control the operation of the motor 5 and the feeding valve.

[0056] like Figure 3 As shown, the bottom wall of the mixing box 3 is bolted and fixedly connected with a protection box 18 for protecting the gear 10 and the rack 9, the limit plate 12 passes through the protection box 18 and is bolted and fixedly connected with the protection box 18, and the rack 9 is slidably matched with the protection box 18. The protection box 18 can provide an independent operating space for the gear 10 and the rack 9, greatly reducing the problem of the gear 10 and the rack 9 running jamming due to excessive raw materials, and also prevents raw materials and water from entering the motor 5 and the rotating parts, affecting the operation of the motor 5 and the rotating parts; thereby ensuring the normal operation of the entire device.

[0057] like Figure 2 As shown, the material dividing assembly includes a plurality of material dividing shells 13, the tops of the material dividing shells 13 are respectively connected to the bottoms of the raw material boxes 2 adjacent thereto, and the bottoms of the material dividing shells 13 are all connected to the feeding trough.

[0058] like Figure 5 and Figure 6 As shown, a dividing block 14 is rotatably fitted inside the dividing shell 13, and a plurality of receiving grooves are provided on the dividing block 14; a weight sensor 15 is bolted to the bottom wall of the receiving groove, and a control valve 16 is bolted to the side of the receiving groove close to the dividing shell 13; a rotating part for rotating the dividing block 14 is bolted to the inner wall of the dividing shell 13, and in this embodiment, a motor 19 is selected as the rotating part, and an output shaft of the motor 19 is coaxially bolted to the dividing block 14; a controller is used to control the operation of the motor 19 and receive signals from the weight sensor 15; a sealing layer is fixedly bonded between the inner wall of the dividing shell 13 and the rotating gap of the dividing block 14.

[0059] like Figure 1 As shown, the material taking assembly includes a material taking pump 17 , which is bolted and fixedly connected to the lower side wall of the mixing box 3 , and the controller is used to control the operation of the material taking pump 17 .

[0060] The specific implementation process is as follows: Figure 2 For example, first, various types of raw materials are placed in each raw material box 2 respectively. After the raw materials are placed, the required amount of each raw material is input through the controller, and the control valve 16 is opened by the controller, so that each raw material flows into the receiving tank through the control valve 16. When the weight sensor 15 detects that the weight of the raw material in the receiving tank has reached the required amount, the controller will close the control valve 16 and start the motor 19 at the same time; at this time, the output shaft of the motor 19 will drive the dividing block 14 to rotate 180°, aligning the receiving tank filled with raw materials with the feeding tank, and then the controller will open the control valve 16 to discharge the raw materials into the feeding tank.

[0061] Since the volumes of the receiving tanks are the same, the amounts of raw materials that can be accommodated are also the same, and the maximum storage weights of the same raw materials are also the same; if the required amount of raw material weight is greater than the maximum storage weight, when the weight sensor 15 detects that the weight of the raw material in the receiving tank has reached the maximum storage weight, the controller will close the control valve 16 and start the motor 19 at the same time; at this time, the output shaft of the motor 19 will drive the material dividing block 14 to rotate 90°, aligning the receiving tanks that are not filled with raw materials with the raw material box 2 in turn, and opening the control valves 16 in turn until the total amount of this type of raw material delivered reaches the required amount, at which time the controller will close all the control valves 16 and stop the delivery of this type of raw material.

[0062] During this process, the sealing layer can effectively prevent the slag from entering the rotation gap between the inner wall of the dividing shell 13 and the dividing block 14 , thereby affecting the rotation of the dividing block 14 and the dividing shell 13 .

[0063] After all the raw materials are put into the feeding trough according to the required amount, the controller will open the feeding valve, and all the raw materials will fall into the mixing box 3; Figure 3 For example, at this time, the controller starts the motor 5, and the output shaft of the motor 5 drives the connecting rod 6 to rotate. Since the connecting rod 6 and the slider 7 are hinged, and the slider 7 is slidably matched with the sliding ring 8, when the connecting rod 6 rotates, it will drive the slider 7 to rotate. At the same time, the slider 7 will also slide in the sliding ring 8 and generate thrust on the sliding ring 8; and since the sliding ring 8 is fixedly connected with the rack 9 with bolts, and the rack 9 and the limit plate 12 are slidably matched, the thrust generated by the rotation of the slider 7 will push the sliding ring 8 and the rack 9 to slide along the length direction of the limit plate 12. Since the rack 9 and the gear 10 are meshed with each other, all the gears 10 will rotate, thereby driving the multiple groups of stirring rods 11 to rotate. In this process, the output shaft of the motor 5 drives the connecting rod 6 to rotate, so that the rack 9 slides left and right, and drives the gear 10 to rotate repeatedly, so as to achieve large-scale stirring and mixing of the raw materials.

[0064] When the raw materials are stirred and mixed, the required nutrients are obtained; when the materials need to be taken for use, only the required weight of the nutrients needs to be input through the controller, and the controller will turn on the material pump 17 and discharge the corresponding weight of the nutrients.

[0065] The present invention adopts a combined structure of a connecting rod 6, a slider 7, a sliding ring 8, a rack 9 and a gear 10, and realizes the synchronous rotation of multiple motors 5 and multiple groups of stirring rods 11 through a single power source of a motor 5, thereby increasing the stirring range, increasing the mixed volume, and improving the principle utilization rate and the uniformity and efficiency of raw material mixing. The operation of the entire device is completed through a controller. The user only needs to input the required amount of raw materials and a start command to automatically complete the distribution, stirring and mixing process of the raw materials, and the operation is simple and easy. The design of the material distribution shell 13 and the material distribution block 14 in the present invention ensures that each raw material is accurately distributed to the feed trough according to the required amount, avoids the problem of raw material waste and inaccurate proportions, and helps to obtain a nutrient formula that meets the requirements.

[0068] The specific implementation process is as follows: when the rack 9 slides left and right, the rack 9 will also slide left and right with the scrapers 901 on both sides; the scrapers 901 will scrape the raw materials on both sides of the stirring rod 11 and push them to the stirring rod 11, so that the stirring of the raw materials is more uniform and comprehensive.

[0070] As attached Figure 3 As shown, the difference from the above embodiment is that a gravity sensor is embedded in the bottom wall of the mixing box 3, and the controller is used to receive the signal of the gravity sensor.

[0071] The specific implementation process is as follows: during the entire configuration process, the gravity sensor can detect the total weight of the raw materials; after the configuration is completed, the gravity sensor can detect the total weight of the finished nutrient products; this makes it easy for users to judge the weight of the required nutrients and whether the subsequent material intake is sufficient.

[0072] Embodiment 4:

[0073] As attached Figure 1 and Figure 2 As shown, the difference from the above embodiment is that a top cover 201 is detachably connected to the top of the raw material box 2 by threads.

[0074] The specific implementation process is as follows: when the raw materials are added, the top cover 201 can be opened to facilitate the feeding; after the feeding is completed, the top cover 201 is closed to prevent foreign impurities from entering the device, thereby ensuring the operating stability of the device and protecting the quality of the finished nutrient product.

[0075] Embodiment 5:

[0076] As attached Figure 3 and Figure 4 As shown, the difference from the above embodiment is that an elastic brush is fixedly bonded to one end of the stirring rod 11 away from the gear 10 .

[0077] The specific implementation process is as follows: during the mixing process, part of the raw materials will adhere to the scraper 901 and the side wall of the mixing box 3; the brush can effectively clean and scrape the raw materials attached to the scraper 901 and the side wall of the mixing box 3, thereby improving the utilization rate of the raw materials; at the same time, it also reduces the weight of the scraper 901 and the mixing box 3, reducing the burden on the device.

[0078] Embodiment 6:

[0079] As attached Figure 2 As shown, the difference from the above-mentioned embodiment is that the feeding trough is arranged in a conical shape.

[0080] The specific implementation process is as follows: during the feeding process, the conical feeding trough makes the feed port larger and the storage space larger, so that more raw materials can be transported and stored. Due to the conical structure, the side wall of the feeding trough has a certain slope, so that the raw materials will slide to the bottom of the feeding trough, thereby facilitating the transmission of the raw materials.

[0086] S4, finished product taking: open the taking pump 17, take out a specified amount of nutrients, and then use it.

[0087] The specific implementation process is as follows: according to the specific needs of the grassland to be restored, determine the type and quantity of raw materials required, and then put these raw materials into the pre-prepared raw material boxes 2 respectively. After the raw materials are put in, input the proportion of each raw material in the required nutrients through the controller, and then start the motor 19 to transport each raw material to the mixing box 3 according to the specified ratio; at this time, start the motor 5 again to stir and mix the raw materials to make nutrients; finally, open the material pump 17 to obtain the specified amount of nutrients for use.

[0088] The present invention can accurately control the amount and ratio of each raw material through the design of the material dividing shell 13 and the material dividing block 14, ensuring the accuracy and effectiveness of the nutrient configuration process, while improving the mixing efficiency and uniformity of the raw materials, and greatly improving the quality of the finished nutrient product.

[0089] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
