[0037] The fertilization mechanism includes a fixed block and a driving shaft. A storage box is fixedly connected to the upper side of the tiller. A rubber hose is fixedly connected to the lower end of the storage box. A connecting part is fixedly connected to the lower end of the rubber hose.

[0038] When the connecting shaft moves upward, it drives the pressure block to move upward. When the connecting shaft contacts the rubber friction block inside the vertical groove, the connecting shaft rotates clockwise under the friction force of the rubber friction block. The pressure block rotates leftward along with the connecting shaft to further increase the inclination of the chute and accelerate the falling of the fertilizer in the chute.

[0039] The tamping mechanism includes a bearing plate, an eccentric part and a right eccentric wheel.

[0041] The front side of the mounting plate is rotatably connected to the right end of the tiller with a connecting plate, the front end of the driven shaft is rotatably connected to the connecting plate, and the front end surface of the connecting plate is fixedly connected to the rear end surface of the left eccentric wheel; the right side of the mounting plate is rotatably connected to the right driven sprocket, the front side of the right driven sprocket is fixedly connected to a transmission shaft, the transmission shaft is rotatably connected to the connecting plate, and the transmission sprocket is transmission-connected to the right driven sprocket through a chain; by adjusting the transmission ratio between the transmission sprocket and the right driven sprocket and the left driven sprocket, the mobile wheel rotates to drive the fertilizing device to move, the left side of the fertilizing device performs pit-breaking and fertilizing work, and the right side performs soil tamping work on the soil pit filled with fertilizer through a tamping mechanism.

[0042] In order to further improve the fertilization effect of the present invention, two groups of connecting plates, driven shafts and transmission shafts are arranged symmetrically along the mounting plate. Several groups of tillers, pressure mechanisms, fertilization mechanisms and tamping mechanisms are arranged. Each group of pressure mechanisms is arranged on the right side of the tiller, so that when the fertilization device moves to the right, the fertilization device can perform multiple groups of fertilization operations at the same time.

[0043] Working principle: Place the fertilization device at the fertilization site, and use the traction device to drive the fertilization device to move to the left. When the fertilization device moves to the left, the tiller loosens the soil surface;

[0044] When the moving wheel rotates, it drives the transmission sprocket fixedly connected to it to rotate, and the transmission sprocket drives the left driven sprocket and the right driven sprocket to rotate through the chain, and the left driven sprocket drives the driven shaft fixedly connected to it to rotate;

[0045] The driven shaft drives the left eccentric wheel fixedly connected thereto to rotate centrifugally. When the protruding part of the left eccentric wheel rotates to the lower side to apply pressure to the upper end of the arc rod, the arc rod is forced to drive the connecting shaft connected thereto to move downward, and the connecting shaft drives the pressure block connected thereto to move downward, so that the pressure block exerts pressure on the loosened soil to create a soil pit when moving downward. The kinetic energy of the pressure block moving downward is converted into stress and deformation energy between the ground and the pressure block, causing the ground to be subjected to the stress and pressure of the pressure block, causing extrusion and deformation, thereby increasing the hardness and density of the soil;

[0046] When the pressure block moves downward, the driving shaft drives the baffle plate connected to it to move downward under the elastic force of the connecting spring, and the baffle plate gradually rotates to a horizontal state under the limit of the horizontal groove inside the connecting part to block the fertilizer;

[0047] When the pressure block completes the pit-breaking work and moves upward to reset under the elastic force of the reset spring, the pressure block applies thrust to the drive shaft through the push block, and the baffle rotates under the limit of the horizontal groove as the drive shaft moves upward, so that the left and right drive shafts rotate relatively. When the drive shaft rotates, a gap is generated between the connecting part, and the fertilizer falls on the upper part of the pressure block through the gap, and falls into the soil pit through the inclined groove, thereby realizing the fertilization of wheat;

[0048] When the right driven sprocket rotates, it drives the transmission shaft fixedly connected thereto to rotate, and the transmission shaft drives the eccentric part and the right eccentric wheel fixedly connected thereto to rotate. When the eccentric part rotates centrifugally, the pressure effect of the right eccentric wheel on the compacting part is accelerated;

[0049] When the protruding part of the right eccentric wheel rotates to the lower side to apply pressure to the force-bearing plate, the force-bearing plate drives the sliding rod fixedly connected thereto to move downward, and the sliding rod drives the compacting part fixedly connected thereto to move downward. When the compacting part moves downward, the soil pit filled with fertilizer is compacted, thereby realizing the fertilization of wheat; the loosened soil is pitted front and back to increase the density and hardness of the soil pit, and then fertilizer is added to the soil pit, and then the soil is buried above the fertilizer under the pressure of the compacting part, and the buried soil is squeezed under the squeezing of the compacting part to increase the density of the buried soil, so that the fertilizer is well sealed, and the slow release of fertilizer is realized by strengthening the sealing of the soil, so as to avoid complicated labor operations such as secondary soil turning and fertilization after fertilizer loss.

[0050] However, after analysis, it was found that the patent is mainly used for fertilizing cultivated land or before planting, but cannot be used for topdressing, and the scope of use is insufficient.

[0051] Reference Figure 1-6 As shown, this embodiment provides a fertilizing device for wheat planting, comprising:

[0052] A bracket 1, the bracket 1 is connected to the traction device, and a plurality of running wheels 3 are arranged on the bracket 1;

[0053] A plurality of fertilizer hoppers 2, wherein the plurality of fertilizer hoppers 2 are independently arranged on the bracket 1; a regulating component for controlling the outflow speed of the fertilizer is arranged at the bottom outlet of the fertilizer hopper 2;

[0054] A material distribution component, the material distribution component includes a material distribution channel 4 arranged at the bottom of the fertilizer hopper 2, and the regulating component is arranged corresponding to the material distribution channel 4, and the regulating component extends into the material distribution channel 4; a spiral material guide rod 5 is rotatably connected in the material distribution channel 4, and the spiral material guide rod 5 is transmission-connected to the walking wheel 3;

[0055] The bulk material assembly includes a bulk material plate 6 which is rotatably connected to the bottom end of the spiral material guide rod 5. The fertilizer sent down by the spiral material guide rod 5 falls on the bulk material plate 6 and is thrown off to be bulked;

[0056] The tail plate 7 is rotatably arranged at the tail end of the bracket 1 and is used for shaking the wheat plants and sweeping off the fertilizer that has fallen onto the plants.

[0057] The present invention discloses a fertilizing device for wheat planting. The bracket 1 enables the whole device to be connected with a tractor, so that the device can be towed by the tractor, and no manual fertilization is required, which can improve the efficiency of fertilization and facilitate the improvement of the efficiency of wheat topdressing. The regulating component at the bottom of the fertilizer hopper 2 can adjust the outflow speed of the fertilizer in the fertilizer hopper 2, which is convenient for fertilizing wheat at different periods, thereby improving the application scope of the device and facilitating its popularization and use. When fertilizing, the walking wheel 3 touches the ground and rotates, driving the spiral guide rod 5 to transport the fertilizer flowing down from the regulating component, so that the ability of the spiral guide rod 5 to transport fertilizer is similar to that of the walking wheel. The distance hook ensures that the amount of fertilizer within a unit distance is fixed, avoiding the disadvantage of uneven fertilizer amount per unit area in manual fertilization, and improving the uniformity of fertilization. At the same time, when the walking wheel 3 does not rotate, the fertilizer cannot fall through the spiral guide rod 5. Therefore, after the tractor lifts the equipment through the bracket 1, the fertilizer will not fall, avoiding the waste of fertilizer, avoiding the accumulation of fertilizer when turning or reversing, and avoiding the accumulation of fertilizer to burn seedlings; when fertilizing, the walking wheel 3 drives the bulk plate 6 to rotate, and the fertilizer falling on the bulk plate 6 is thrown away, the force is constant, the fertilizer application range is fixed, and the uniformity of fertilization is improved. The present invention has a simple structure, is easy to use, can automatically control the efficiency of fertilization, and is suitable for the fertilization needs of wheat in different growth periods; and the fertilizer can be evenly spread during fertilization, which improves the uniformity of fertilizer distribution during the fertilization process, improves the effect of fertilization, and increases the yield of wheat.

[0058] In one embodiment of the present application, a traction hole 39 is provided on the bracket 1 to facilitate traction by a tractor. At the same time, the bracket 1 can be lifted and lowered under the control of the tractor. When turning during mid-transportation and fertilization, the device can be lifted to prevent the fertilizer from falling.

[0059] In one embodiment of the present application, a tail rack 36 is provided at the rear of the bracket 1, a tail shaft 37 is provided at the rear of the tail rack 36, and a tail plate 7 is rotatably connected to the tail shaft 37 via a deflection frame 38. When fertilizing, the tail plate 7 is used to move the wheat plants at the rear to cause the fertilizer to fall.

[0060] In one embodiment of the present application, the angle of the tail plate 7 can be adjusted according to the growth period of the wheat, which is suitable for shifting wheat in different growth periods, thereby ensuring the shifting effect and reducing damage to the wheat.

[0061] A further optimized solution is provided, wherein the regulating and controlling component comprises a first control plate 8 fixedly connected to the bottom end of the inner wall of the fertilizer hopper 2, and a second control plate 9 is slidably connected to the lower end surface of the first control plate 8; a plurality of first through holes 10 are arranged in an array on the first control plate 8, and a plurality of second through holes 11 are arranged in an array on the second control plate 9, and the first through holes 10 and the second through holes 11 are arranged correspondingly; an adjusting component is arranged on the side wall of the second control plate 9; the adjusting component comprises an adjusting rack 12 fixedly connected to the side wall of the second control plate 9, the adjusting rack 12 is meshingly connected to an adjusting gear 13, an adjusting shaft 14 is fixedly connected to a side of the adjusting gear 13 away from the second control plate 9, the adjusting shaft 14 extends out of the distributing channel 4 and is rotatably connected to the distributing channel 4, and an adjusting handle 15 is fixedly connected to one end of the adjusting shaft 14 extending out of the distributing channel 4. When it is necessary to adjust the falling speed of the fertilizer, the adjusting handle 15 is rotated, and the adjusting gear 13 is driven to rotate through the adjusting shaft 14. The adjusting gear 13 drives the adjusting rack 12 meshing therewith to move parallel to each other, and drives the second control plate 9 to slide. The sliding of the second control plate 9 causes the relative position of the second through hole 11 and the first through hole 10 to be misaligned and offset, thereby changing the flow area of ​​the fertilizer and changing the flow rate of the fertilizer. The adjustment range is that the fertilizer flow rate is the largest when the first through hole 10 and the second through hole 11 are directly opposite to each other, and the fertilizer will not flow when the first through hole 10 and the second through hole 11 are completely offset. It can be determined according to the growth of wheat, the fertility of the land and the rainfall conditions, and it is convenient to fertilize in different growth processes of wheat, thereby expanding the scope of application of the fertilization device and facilitating its promotion and application.

The area of ​​the second control plate 9 is smaller than the cross-section of the material distribution channel 4. When fertilizing, the spiral guide rod 5 drives the eccentric drive block 17 to rotate, and the eccentric drive block 17 pushes the inner wall of the force frame 16, so that the second control plate 9 slides at the bottom end of the first control plate 8, thereby causing the first through hole 10 and the second through hole 11 to produce misaligned shaking, thereby crushing the agglomerated fertilizer and preventing the fertilizer blocks from affecting the fertilization process; the reset spring 33 is compressed and reset with the movement of the second control plate 9 to prevent it from getting stuck, thereby improving the smoothness of the movement of the second control plate 9 and improving the stability of the equipment operation; and the support plate 32 is supported at the bottom end of the second control plate 9 to ensure that the second control plate 9 is within the support range of the support plate 32 during the movement process, thereby ensuring its stability.

[0063] In one embodiment of the present application, the cross-section of the first through hole 10 is designed to be an inverted cone with a large inlet and a small outlet, which can prevent small pieces of fertilizer from clogging the first through hole 10; the agglomerated fertilizer falls to the bottom of the first through hole 10 and is crushed by the staggered movement of the first through hole 10 and the second through hole 11 to avoid affecting fertilization.

The outer wall of the central shaft 18 is provided with a spiral guide plate 19, when the central shaft 18 does not drive the guide plate 19 to rotate, it can prevent the fertilizer from passing through, and prevent the fertilizer from falling and causing the seedlings to burn due to fertilizer accumulation; when fertilizing, the central shaft 18 drives the guide plate 19 to rotate, which can drive the fertilizer to pass through, and at the same time can control the dropping speed of the fertilizer; the driven pull slides longitudinally in the inner cavity at the bottom end of the central shaft 18, and the walking wheel 3 drives the driven shaft 20 to rotate through the transmission assembly, thereby driving the central shaft 18 to rotate, and then driving the bulk material plate 6 to evenly spread the fertilizer to the surroundings.

[0065] Further optimization scheme, the transmission assembly includes a driving shaft 21 connected to the travel wheel 3, the driving shaft 21 is fixed with a driving disk 22, and a plurality of L-shaped connecting rods 23 are provided on the driving disk 22 for transmission, and the L-shaped connecting rods 23 are connected to the driven disk 24 provided at the bottom of the driven shaft 20 for transmission. When the travel wheel 3 travels, the driving shaft 21 is driven to rotate, and the driving disk 22 at the end of the driving shaft 21 drives the driven disk 24 to rotate through a plurality of L-shaped connecting rods 23, thereby driving the driven shaft 20 to rotate, so that when the travel vehicle traction device moves forward, it can provide power for the bulking plate 6 to throw fertilizer around, without the need for additional power input, reducing the complexity of the structure, facilitating maintenance, and combining the equipment forward movement and fertilizer spreading together for easy control.

[0066] In one embodiment of the present application, a plurality of active holes 25 are provided on the active plate, and a plurality of driven holes 26 corresponding to the active holes 25 are provided on the driven plate 24. The two parts of the L-shaped connecting rod 23 are slidingly connected to the active hole 25 and the driven hole 26 respectively to realize right-angle transmission of power.

[0067] In one embodiment of the present application, the included angle of the L-shaped connecting rod 23 is matched with the included angle between the driving disk 22 and the driven disk 24 to facilitate adjustment, which will not be described in detail here.

[0068] A further optimized solution is that the bulk plate 6 includes a bottom plate 27 arranged below the guide plate 19, the bottom plate 27 is coaxially arranged with the driven shaft 20 and is transmission-connected, and a plurality of arc-shaped vertical plates 28 are fixedly connected to the top end of the bottom plate 27 at circumferentially equal intervals, and the fertilizer falls onto the bottom plate 27 and is thrown off and scattered by the vertical plates 28.
