Description

Technical Field

[0001] This invention relates to an orchard ditching and fertilizer mixing machine, in the field of agricultural machinery technology. Background Technology

[0002] Fruit cultivation accounts for a significant proportion of my country's agricultural planting industry, with relatively good economic benefits per unit area. It is easily integrated with modern service industries such as sightseeing, fruit picking, and recreational activities, making it a crucial industry for adjusting rural industrial structure, increasing farmers' income, and promoting rural revitalization. Currently, my country ranks among the world's leading countries in both fruit planting area and output. Trenching and fertilization is an essential step in fruit tree cultivation, and the quality of this process determines the subsequent growth and yield of the fruit trees. Currently, most areas in my country still rely on manual fertilization. This involves manually digging trenches, filling them with fertilizer, and then manually covering them with soil. This method of orchard trenching and fertilization wastes a significant amount of manpower and resources, and cannot precisely control the trench depth and fertilizer amount, leading to large errors, excessive fertilizer waste, increased production costs, and disruption of the soil's elemental balance. It is no longer suitable for the requirements of modern orchard fertilization management. Factors such as varying terrain, soil hardness, and vehicle shape can cause inconsistent trench depths, resulting in low fertilizer utilization. The replacement of chemical fertilizers with organic fertilizers has become an inevitable trend, and many standards now specify a fertilization model of "organic fertilizer + chemical fertilizer" mixed application. my country's unique orchard planting patterns result in dwarfed fruit trees and limited space, leading to small planting distances for orchard crops, making it difficult for existing machinery to operate effectively. To address these issues, there is an urgent need to develop a reliable fertilizer mixing machine with adaptively adjustable trenching depth that can meet the requirements of "organic fertilizer + chemical fertilizer" fertilization, thereby promoting the green development of agricultural production in my country. Summary of the Invention

[0003] The purpose of this invention is to provide an orchard ditching and fertilizer mixing machine with a reasonable structural design and stable working performance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an orchard ditching fertilizer mixing machine, comprising a tracked motor chassis, a frame, an organic fertilizer discharge system, a chemical fertilizer discharge system, and a transmission system. The tracked motor chassis is used to drive the mixing machine to move; the frame is mounted on the tracked motor chassis; the organic fertilizer discharge system and the chemical fertilizer discharge system are installed side by side in the frame, and their discharge ports are arranged along the length of the fertilizer ditch; the transmission system is connected to the organic fertilizer discharge system and the chemical fertilizer discharge system respectively, and realizes the discharge of fertilizer by the organic fertilizer discharge system and the chemical fertilizer discharge system under the action of the power system.

[0005] Furthermore, it also includes a fertilizer mixing system, which is located below the discharge ports of the organic fertilizer discharge system and the chemical fertilizer discharge system; thereby mixing the organic fertilizer discharged from the organic fertilizer discharge system and the chemical fertilizer discharged from the chemical fertilizer discharge system together.

[0006] Preferably, the mixed fertilizer system includes an organic fertilizer discharge system guide plate and a chemical fertilizer discharge system guide plate; the organic fertilizer discharge system guide plate includes an organic fertilizer three-channel guide plate bottom plate, organic fertilizer three-channel guide plate side plates, and organic fertilizer three-channel guide plate inner wall baffle; a groove is opened on the organic fertilizer three-channel guide plate bottom plate; there are two organic fertilizer three-channel guide plate side plates, which are installed on both sides of the organic fertilizer three-channel guide plate bottom plate; the organic fertilizer three-channel guide plate inner wall baffle is installed on the organic fertilizer three-channel guide plate bottom plate and is opposite to the groove.

[0007] The fertilizer discharge system includes a fertilizer guide plate, fertilizer guide plate side plates, fertilizer guide plate cover plate, and fertilizer guide plate diversion plate. There are two fertilizer guide plate side plates, one end of which is connected to both sides of the fertilizer guide plate bottom plate, and the other end of which is connected to both sides of the fertilizer guide plate cover plate. The fertilizer guide plate diversion plate is located in the middle of the fertilizer guide plate bottom plate, and one end of which is connected to the fertilizer guide plate bottom plate.

[0008] The fertilizer guide plate of the chemical fertilizer discharge system is located directly above the fertilizer guide plate of the organic fertilizer discharge system. The chemical fertilizer falls from the fertilizer guide plate of the chemical fertilizer discharge system into the fertilizer guide plate of the organic fertilizer discharge system, and the two fertilizers are mixed through collision.

[0009] Preferably, the organic fertilizer discharge system includes a primary organic fertilizer discharge system and a secondary organic fertilizer discharge system. The primary organic fertilizer discharge system includes an organic fertilizer tank and a primary organic fertilizer discharge spiral chamber. The organic fertilizer tank is installed above the primary organic fertilizer discharge spiral chamber and is used to hold organic fertilizer. There are two sets of primary organic fertilizer discharge spiral chambers arranged side by side. The secondary organic fertilizer discharge system includes a secondary organic fertilizer discharge spiral chamber, and the inlet of the secondary organic fertilizer discharge system is vertically opposite to the outlet of the primary organic fertilizer discharge spiral chamber.

[0010] Preferably, the discharge spiral of the secondary discharge spiral chamber of organic fertilizer is an opposing spiral with the same axis and opposite spiral directions; the feed inlet of the secondary discharge spiral chamber of organic fertilizer is located above the discharge spiral, and the discharge outlet is located below the discharge spiral, with the discharge outlet close to the middle of the two feed inlets; the transmission system is connected to one end of the discharge spiral to provide power to it.

[0011] Preferably, the organic fertilizer box includes an organic fertilizer box body and a fertilizer distribution plate; the fertilizer distribution plate is located at the bottom of the organic fertilizer box body and between the two discharge ports.

[0012] Preferably, the fertilizer discharge system includes a fertilizer tank and a fertilizer discharge spiral chamber. The fertilizer tank is detachably installed above the fertilizer discharge spiral chamber. The fertilizer discharge spiral chamber has two inlets. A fertilizer separating plate is installed between the fertilizer discharge spiral chamber inlet and the fertilizer tank outlet. The two ends of the fertilizer separating plate are close to the fertilizer discharge spiral chamber inlet. Fertilizer slides into the fertilizer discharge spiral chamber inlet from the two ends of the fertilizer separating plate and then slides out from the fertilizer discharge spiral chamber outlet.

[0013] Preferably, the fertilizer distribution plate is inverted V-shaped, with its top close to the fertilizer box outlet and its bottom two ends close to the fertilizer discharge spiral chamber inlet.

[0014] Preferably, the fertilizer discharge spiral chamber includes a fertilizer discharge spiral chamber body and a discharge spiral; the discharge spiral is horizontally installed in the fertilizer discharge spiral chamber body and is a counter-spiral structure with opposite spiral directions, one end of which is connected to a power device and rotates under the action of the power device; the fertilizer discharge spiral chamber inlet is located above the discharge spiral.

[0015] Furthermore, it also includes a trenching depth monitoring and control system, which is installed below the frame and used to control the trenching depth.

[0016] Workflow: Organic fertilizer falls from the organic fertilizer tank into the inlet of the primary organic fertilizer discharge system. A servo motor drives the primary discharge screw to rotate, continuously transporting the fertilizer from the screw chamber to the discharge hopper and then into the secondary organic fertilizer discharge system. The servo motor then drives the secondary discharge screw to continuously transport the organic fertilizer from the screw chamber to the outlet in the middle of the secondary discharge system, where it falls into the three-channel guide plate of the mixed fertilizer system. Chemical fertilizer falls from the chemical fertilizer tank into the chemical fertilizer discharge system. A servo motor drives the chemical fertilizer discharge screw to continuously transport the chemical fertilizer from the screw chamber to the outlet and then into the guide plate of the mixed fertilizer system. The two types of fertilizers entering the mixed fertilizer system are mixed through collision and impact.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The use of double-helix and opposed-helix fertilizer discharge significantly improves fertilization efficiency. By adjusting the speed of the servo motor, it can adapt to the different fertilization requirements of different fruit tree varieties and different ages of the same variety. The organic fertilizer discharge rate is adjustable from 20-120 kg / min, and the chemical fertilizer discharge rate is adjustable from 5-30 kg / min. This is a significant improvement over the fertilizer discharge rate adjustment range of self-propelled orchard ditching and fertilizing machines currently on the market. At the same time, the amount of fertilizer applied can be monitored and adjusted in real time according to the changes in the machine's operating speed to ensure precise fertilization.

[0019] 2. The organic fertilizer tank and chemical fertilizer tank in the organic fertilizer primary discharge system and chemical fertilizer discharge system are placed side by side, one in front of the other. While ensuring a compact machine size, this significantly increases the fertilizer carrying capacity. The machine can carry organic fertilizer up to 30m of continuous operation at maximum discharge capacity. This effectively solves the problem of small fertilizer carrying capacity and short continuous operation distance of current self-propelled orchard ditching and fertilizing machines on the market, which requires frequent stops for fertilization, thus reducing operating costs. It also resolves the contradiction between miniaturization of agricultural machinery and large-volume application of organic fertilizer in hilly and mountainous areas of southern China. This machine combines the large fertilizer carrying capacity of a scraper-driven ditching and fertilizing machine with the precision discharge of a spiral self-propelled ditching and fertilizing machine, and has a wide range of fertilizer adaptability.

[0020] 3. The trenching depth monitoring and control system effectively solves the problem of low fertilizer utilization caused by inconsistent trenching depths due to factors such as uneven terrain, varying soil hardness, and different vehicle postures. It enables the depth of the fertilization trench to be adaptively adjusted in real time according to changes in terrain, soil, and vehicle posture, ensuring good trench depth stability.

[0056] In a preferred embodiment of this invention, the fertilizer discharge spiral chamber is placed parallel to the organic fertilizer secondary discharge spiral chamber and is located on the same plane as the organic fertilizer primary discharge spiral chamber; the left and right ends of the fertilizer side plate guide plate 502018 are fixedly installed with the sleeve support plates 502016 and 502017 respectively, and maintain a 30° angle with the fertilizer discharge spiral chamber side plates 501 and 502; the fertilizer flows from the fertilizer box through the fertilizer distribution plate 502013 to the feed inlets on both sides of the fertilizer discharge spiral chamber, and the fertilizer is filled into the fertilizer discharge spiral sleeve 502010. The fertilizer discharge spiral 509 is driven by a motor to rotate and transport the fertilizer on both sides to the discharge port of the fertilizer discharge spiral chamber and leave the fertilizer discharge spiral chamber.

[0057] like Figure 9As shown, the organic fertilizer secondary discharge system includes an organic fertilizer secondary discharge spiral chamber 701, an organic fertilizer secondary discharge system connecting longitudinal beam 702, an organic fertilizer secondary discharge system connecting longitudinal beam 703, an organic fertilizer secondary discharge system connecting longitudinal beam 704, an organic fertilizer secondary discharge system connecting longitudinal beam 705, an organic fertilizer secondary discharge system long crossbeam 706, an organic fertilizer secondary discharge system long crossbeam 707, an organic fertilizer secondary discharge system short crossbeam 708, an organic fertilizer secondary discharge system short crossbeam 709, an organic fertilizer secondary discharge system support beam 7010, and an organic fertilizer secondary discharge system support beam 7011; the organic fertilizer secondary discharge system connecting longitudinal beam 702 and 703, the connecting longitudinal beams of the secondary organic fertilizer discharge system, are respectively installed at both ends of the connecting crossbeam 3020 of the secondary organic fertilizer discharge system, and can be detachably installed below the connecting crossbeam 3020; 704 and 705, the connecting longitudinal beams of the secondary organic fertilizer discharge system, are respectively installed at both ends of the connecting crossbeam 3021 of the secondary organic fertilizer discharge system, and can be detachably installed below the connecting crossbeam 3021; ​​the left and right ends of the long crossbeam 706 of the secondary organic fertilizer discharge system are connected to the connecting longitudinal beams 702 and 703 of the secondary organic fertilizer discharge system. Beam 703 is fixedly installed below; the left and right ends of the long crossbeam 707 of the organic fertilizer secondary discharge system are fixedly installed below with the connecting longitudinal beams 704 and 705 of the organic fertilizer secondary discharge system; the short crossbeams 708 and 709 of the organic fertilizer secondary discharge system are symmetrically fixedly installed at the left and right ends of the long crossbeam 706 of the organic fertilizer secondary discharge system; the support beams 7010 and 7011 of the organic fertilizer secondary discharge system are symmetrically fixedly installed on the long crossbeams 706 and 707 of the organic fertilizer secondary discharge system. The distance between the primary fertilizer discharge system support beam 7010 and the secondary fertilizer discharge system short crossbeam 708 is 139mm, and the distance between the secondary fertilizer discharge system support beam 7011 and the secondary fertilizer discharge system short crossbeam 709 is 139mm. The secondary fertilizer discharge spiral chamber 701 is detachably installed above the secondary fertilizer discharge system support beams 7010 and 7011. Organic fertilizer enters the secondary fertilizer discharge system inlet through the discharge hopper of the primary fertilizer discharge system, and is transported to the discharge outlet of the secondary fertilizer discharge system and leaves the secondary fertilizer discharge system via the secondary fertilizer discharge spiral chamber 701010.

[0058] like Figure 10As shown, the organic fertilizer secondary discharge spiral chamber 701 includes side plates 70101 and 70102, end covers 70103 and 70104, bearing support plates 70105 and 70106, bearing seats 70107 and 70108, spiral sleeve 70109, spiral 701010, and bottom plate 701011; organic fertilizer... The side plates 70101 and 70102 of the secondary fertilizer discharge spiral chamber are fixedly installed on both sides of the bottom plate 701011 of the secondary fertilizer discharge spiral chamber; the end covers 70103 and 70104 of the secondary fertilizer discharge spiral chamber are fixedly installed at the front and rear ends of the bottom plate 701011 of the secondary fertilizer discharge spiral chamber; the bearing support plates 70105 and 70106 of the secondary fertilizer discharge spiral chamber are detachably installed at the front ends of the end covers 70103 and 70104 of the secondary fertilizer discharge spiral chamber; the bearings of the secondary fertilizer discharge spiral chamber... Seats 70107 and 70108 are detachably installed on the front ends of bearing support plates 70105 and 70106 of the secondary organic fertilizer discharge spiral chamber, respectively; the secondary organic fertilizer discharge spiral sleeve 70109 is detachably installed on the end covers 70103 and 70104 of the secondary organic fertilizer discharge spiral chamber via a slot; the secondary organic fertilizer discharge spiral 701010 is detachably installed on the end covers 70103 and 70104 of the secondary organic fertilizer discharge spiral chamber via bearing seats 70107 and 70108, respectively. The secondary discharge spiral sleeve of the organic fertilizer is installed concentrically with the primary discharge spiral sleeve of the organic fertilizer. The secondary discharge spiral chamber of the organic fertilizer is placed vertically with the primary discharge spiral chamber of the organic fertilizer. The left and right inlets of the secondary discharge spiral chamber of the organic fertilizer are respectively arranged directly below the discharge hopper of the primary discharge spiral chamber of the organic fertilizer. The organic fertilizer from the primary discharge system falls into the secondary discharge spiral chamber of the organic fertilizer and into the secondary discharge spiral sleeve of the organic fertilizer. It is then transported from both sides to the middle by the secondary discharge spiral to the discharge port of the secondary discharge spiral chamber of the organic fertilizer and leaves the secondary discharge spiral chamber of the organic fertilizer.

[0059] In a preferred embodiment of this invention, the organic fertilizer tank 401 and the chemical fertilizer tank 501 are arranged adjacent to each other, one in front of the other. The secondary organic fertilizer discharge system is arranged in front of the chemical fertilizer discharge system. The organic fertilizer tank 401 is detachably connected to the primary organic fertilizer discharge spiral chamber, and the chemical fertilizer tank 501 is detachably connected to the chemical fertilizer discharge spiral chamber. This ensures that the organic fertilizer falls into the fertilization trench first, which is higher than the chemical fertilizer, to meet the requirement that the application depth of organic fertilizer is greater than that of chemical fertilizer.

[0060] like Figure 11As shown, the trenching depth monitoring and control system is detachably installed below the secondary organic fertilizer discharge system. The trenching depth is adjusted via a hydraulic push rod. It includes STP-23L ranging sensors 801, 802, 803, and 804; ground height monitoring sensor mounting plates 805, 806, and 807; and trench depth monitoring sensor mounting plate 808. STP-23L ranging sensors 801, 802, 803, and 804 are detachably installed below the ground height monitoring sensor mounting plate and the trench depth monitoring sensor mounting plate, respectively. Ground height monitoring sensor mounting plate 805... Sensors 806, 807, and trench depth monitoring mounting plate 808 can be detachably installed below the long crossbeam of the organic fertilizer secondary discharge system. The four sensors are installed in pairs on the same plane. The first group of STP-23L distance measuring sensors is mainly responsible for capturing the distance H1 between the sensor and the bottom of the trench after trenching. The second group of STP-23L distance measuring sensors is mainly responsible for measuring the distance H2 between the un-trenched ground and the sensor on the same plane at the same time. After obtaining the two distance values, the trench depth H at a certain time can be obtained by subtracting H1 from H2. The measured trenching depth H is compared with the standard trenching depth S set before operation. When H is greater than S, the microcontroller controls the hydraulic valve to shorten the length of the hydraulic push rod, reducing the trenching depth H; when H is less than S, the microcontroller controls the hydraulic valve to extend the length of the hydraulic push rod, increasing the trenching depth H. This allows the trenching depth H to be adaptively adjusted in real time according to changes in terrain and topography, ensuring consistent trench depth, improving fertilizer utilization efficiency, and reducing the occurrence of inconsistent trenching depths caused by factors such as uneven terrain, different soil hardness, and different vehicle posture.

[0061] In a preferred embodiment of this invention, the fertilizer mixing system includes a three-channel organic fertilizer guide plate and a chemical fertilizer guide plate. The chemical fertilizer discharge guide plate is located directly above the three-channel organic fertilizer guide plate. The chemical fertilizer falls from the chemical fertilizer discharge guide plate into the three-channel organic fertilizer guide plate, and the two fertilizers are mixed through collision. The specific structure is as follows:

[0062] like Figure 12As shown, the three-channel organic fertilizer guide plate includes a base plate 90101, side plates 90102 and 90103, inner wall plates 90104 and 90105, a cover plate 90106, and damping hinges 90107 and 90108. One side of the side plates 90102 and 90103 is fixedly installed on the left and right sides of the base plate 90101, while the other side is free. A groove is opened in the middle of the base plate 90101, and its top is detachably installed on the side plate 70101 or 70102 of the secondary fertilizer discharge spiral chamber via the damping hinges 90107 and 90108, allowing the organic fertilizer application angle to be adjusted according to actual operating conditions. The organic fertilizer three-channel guide plate inner wall panels 90104 and 90105 are triangular in shape and symmetrically fixed on both sides of the trench. The organic fertilizer three-channel guide plate cover plate 90106 is connected to the inner wall panels 90104 and 90105 on both sides, and the bottom is connected to the bottom plate 90101 of the organic fertilizer three-channel guide plate. Thus, the inner wall panels 90104 and 90105 and the top of the organic fertilizer three-channel guide plate cover plate 90106 form an opening. This divides the organic fertilizer into three flow directions. The organic fertilizer in the left and right channels falls into the left and right sides of the fertilization trench under the guidance of the side panels 90102 and 90103 of the organic fertilizer three-channel guide plate, while the organic fertilizer in the middle channel falls directly into the middle of the fertilization trench through the trench. This makes the organic fertilizer in the fertilization trench evenly distributed, effectively accelerating the absorption of organic fertilizer nutrients and improving fertilizer utilization.

[0063] like Figure 13 As shown, the fertilizer guide plate includes a fertilizer guide plate cover plate 90201, fertilizer guide plate side plates 90202 and 90203, fertilizer guide plate bottom plate 90204, fertilizer guide plate diversion plates 90205 and 90206, and fertilizer guide plate damping hinges 90207 and 90208; the fertilizer guide plate side plates 90202 and 90203 are fixedly installed on the left and right sides of the fertilizer guide plate bottom plate 90204; the fertilizer guide plate diversion plates 90205 and 90206 are symmetrically fixedly installed on the fertilizer guide plate bottom plate. At the middle of the bottom plate 90204, the two fertilizer guide plates form a 60° angle, allowing the fertilizer to be transported more evenly to the left and right sides. The fertilizer guide plate cover 90201 is fixedly installed above the side plates 90202 and 90203 of the fertilizer guide plate. The top of the bottom plate 90204 is detachably connected to the fertilizer discharge spiral chamber 502 via the fertilizer guide plate damping hinges 90207 and 90208, enabling the fertilizer guide plate to transport fertilizer at multiple angles.

[0064] The transmission system includes drive motor assemblies for the primary organic fertilizer discharge system, the secondary organic fertilizer discharge system, and the chemical fertilizer discharge system. Upon receiving a corresponding screw speed control signal, the primary organic fertilizer discharge system drive motor transmits power to the driving sprocket in the primary organic fertilizer discharge system. The driving sprocket then transmits power to the driven sprocket via a chain, driving the two discharge screws in the primary organic fertilizer discharge system to rotate. The secondary organic fertilizer discharge system drive motor is directly connected to the secondary organic fertilizer discharge screw via a coupling, ensuring that the speed of the secondary organic fertilizer discharge screw is the same as the speed of the two discharge screws in the primary organic fertilizer discharge system, achieving synchronous transport of organic fertilizer. The chemical fertilizer discharge system drive motor is directly connected to the chemical fertilizer discharge screw via a coupling, driving the chemical fertilizer discharge screw to quantitatively transport fertilizer from the fertilizer tank to the mixing system for fertilizer mixing. This allows for separate control of the screw speed and discharge volume of the three systems: the primary organic fertilizer discharge system, the secondary organic fertilizer discharge system, and the chemical fertilizer discharge system.

[0065] The above embodiments are merely preferred embodiments of the present invention and do not constitute a limitation thereof. Any extensions, modifications, or equivalent substitutions made by those skilled in the art without departing from the principles of the present invention should be included within the scope of protection of the present invention.
