Description

Technical Field

[0001] This utility model relates to the field of greenhouse planting equipment technology, specifically a one-time forming machine for ridge making in greenhouse planting. Background Technology

[0002] In greenhouse cultivation, ridging is an important agricultural operation. Currently, there are various equipment and methods available for ridging in greenhouse cultivation. Common ridging machines are diverse, such as walk-behind ridging machines, which are compact and well-suited for operation in the relatively confined space of greenhouses; and overhead ridging machines, powered by tractors, which can operate efficiently in larger greenhouse areas. These ridging devices typically use rotating blades, plows, or shovels to loosen the soil and pile it into ridges.

[0003] Most existing one-time ridging machines for greenhouse cultivation can only create ridges of a fixed width, failing to adapt to the needs of different crops or planting methods. If multiple crops need to be planted, multiple machines of different specifications are required, increasing purchase costs. Furthermore, the fixed-height smoothing plates of existing one-time ridging machines can only match specific ridge heights. When adjusting the ridge height for different crops, the smoothing plate may not fit the ridge surface, affecting the quality of the ridge. Additionally, existing one-time ridging machines require separate sowing and fertilization after ridging, increasing operational steps and time, extending the planting cycle, and impacting work efficiency.

[0004] To address these issues, this invention provides a one-time ridge-forming machine for greenhouse planting. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-3 A one-time ridge-forming machine for greenhouse planting includes a fixed frame 1. A traction rod 10 is fixedly connected to the front top of the fixed frame 1, and a roller frame 11 is fixedly connected to the front bottom of the fixed frame 1. Rollers 12 are rotatably connected to both sides of the roller frame 11. Several protruding triangular steel bars arranged in a circular array are welded to the outer walls of the two rollers 12. A ridge width adjustment component 2 is provided on the rear bottom of the fixed frame 1, and a smoothing plate height adjustment component 3 is provided on the rear side of the fixed frame 1. Two integrated planting and fertilization components 4 are provided at the middle of the top of the fixed frame 1.

[0028] The fixed frame 1 is welded from high-strength steel and has an overall rectangular frame structure, providing stable support for the entire equipment. The traction rod 10 is made of solid alloy steel and has a hook structure at its front end for connecting with external traction equipment such as a tractor, so as to drive the entire forming machine to move. The roller frame 11 is made of steel plate and the outer walls of the two rollers 12 are welded with several protruding triangular steel bars arranged in a ring array to prevent the equipment from slipping when moving.

[0029] The ridge width adjustment component 2 includes two side plates 20. The two side plates 20 are fixedly connected to the bottom rear side of the fixed frame 1 and are arranged symmetrically on the left and right. The opposing surfaces of the two side plates 20 are rotatably connected to a bidirectional lead screw 21. A self-locking motor 22 is fixedly connected to the left side wall of the left side plate 20. The output end of the self-locking motor 22 passes through to the right side wall of the left side plate 20 and is fixedly connected to the bidirectional lead screw 21.

[0030] A sliding rod 23 is fixedly connected to the inner walls of the left and right sides of the fixed frame 1 directly above the double-acting screw 21. Moving blocks 24 that are slidably connected to the outer walls of the sliding rod 23 are threaded to the left and right sides of the outer wall of the double-acting screw 21. The two moving blocks 24 are symmetrically arranged on the left and right sides and fixed rods 25 are fixedly connected to their rear sides. Ridging pears 26 are fixedly connected to the bottom of the two fixed rods 25.

[0031] When the equipment is working, it is connected to an external traction device, such as a tractor, via the traction rod 10 on the front top of the fixed frame 1. Under the action of traction force, the whole unit moves. The rollers 12 on the roller frame 11 at the front bottom of the fixed frame 1 contact the ground, and the protruding triangular steel strips on their outer walls rotate with the rollers 12 to prevent slippage and prepare for subsequent ridging. As the equipment moves forward, the ridge width adjustment component 2 on the rear bottom of the fixed frame 1 starts to work. According to the planting needs, the self-locking motor 22 on the left side plate 20 is activated to drive the bidirectional lead screw 21 to rotate. Since the threads of the left and right sections of the bidirectional lead screw 21 are opposite, and the moving blocks 2 on its outer walls... 4. Restricted by the upper sliding rod 23, the two moving blocks 24 move towards or away from each other along the bidirectional screw 21. The fixed rod 25 drives the bottom ridging pears 26 to adjust the spacing. Then, the ridging pears 26 are inserted into the soil, pushing the broken soil towards the middle to form a ridge of a set width. The ridge width adjustment component 2 can be used to flexibly change the ridge width. It can meet the planting standards of various crops without replacing the equipment, improving the versatility and applicability of the equipment. At the same time, precise adjustment of the ridge width can avoid space waste, achieve reasonable dense planting in the limited greenhouse space, and increase the yield per unit area.

[0032] Example 2:

[0033] Please see Figure 4 This embodiment provides a technical solution based on embodiment one: the flat plate height adjustment assembly 3 includes a fixed plate 30, which is fixedly connected to the middle of the rear side wall of the fixed frame 1. A rectangular groove is provided inside the fixed plate 30, and a rotating block 36 is rotatably connected inside the rectangular groove. A lead screw 31 is threadedly connected inside the rotating block 36 through a threaded hole. A knob 32 is fixedly connected to the top of the lead screw 31, and the bottom of the lead screw 31 extends through to the bottom of the fixed plate 30 and is rotatably connected to a connecting block 35.

[0034] Two symmetrical connecting rods 33 are rotatably connected to the bottom rear side of the fixed frame 1. A smoothing plate 34 is fixedly connected to the bottom of the two connecting rods 33. The bottom of the smoothing plate 34 has a chamfered structure to facilitate smoothing the soil. A connecting block 35 is rotatably connected to the middle of the rear side wall of the smoothing plate 34.

[0035] The leveling plate height adjustment component 3 at the rear of the equipment adjusts the formed ridges. Rotating the knob 32 causes the lead screw 31 to move axially along the threaded hole inside the rotating block 36. The rotating block 36 rotates in the rectangular groove inside the fixed plate 30 to prevent motion interference. The leveling plate 34 is driven to rotate around the connection point between the connecting rod 33 and the fixed frame 1 through the connecting block 35. After adjusting to a suitable height, the leveling plate 34 moves with the equipment. The chamfered structure at the bottom of the leveling plate smooths and compacts the soil on the ridge surface, realizing a one-time forming operation of ridging, planting, and fertilization. The leveling plate height adjustment component 3 can match ridge surfaces of different heights to ensure uniform smoothing of various ridge types, avoiding insufficient compaction or excessive rolling in some areas due to differences in ridge height, and improving the flatness of the ridges.

[0036] Example 3:

[0037] Please see Figure 5-6 This embodiment provides a technical solution based on embodiment one: an integrated planting and fertilization component 4. The integrated planting and fertilization component 4 includes a material distribution frame 40. The bottom of the material distribution frame 40 is fixedly connected to a feeding pipe 41 that communicates with its interior. The top of the material distribution frame 40 is fixedly connected to a pre-storage frame 42 that communicates with its interior. The outer wall of the material distribution frame 40 is fixedly connected to a fixing member 43 that is fixedly connected to a fixing frame 1. The bottom of the feeding pipe 41 is fixedly connected to a pear blade 44.

[0038] A motor 45 is fixedly connected to the front side of the pre-storage frame 42. A rotating rod 46 is rotatably connected inside the pre-storage frame 42. The output end of the motor 45 passes through the interior of the pre-storage frame 42 and is fixedly connected to the rotating rod 46. Several equidistant stirring rods 47 are fixedly connected to the outer wall of the rotating rod 46. A motor 48 is fixedly connected to the left side of the distribution frame 40. A rotating disk 49 is rotatably connected inside the distribution frame 40. Several distribution partitions 410 arranged in a ring array are fixedly connected to the outer wall of the rotating disk 49. The output end of the motor 48 passes through the interior of the distribution frame 40 and is fixedly connected to the rotating disk 49.

[0039] The planting and fertilization integrated component 4 at the top of the fixed frame 1 operates synchronously. Seeds or fertilizers stored in the pre-storage frame 42 fall into the distribution frame 40. During this process, the motor 45 on the front side of the pre-storage frame 42 drives the rotating rod 46 and the stirring rod 47 to rotate, preventing the seeds or fertilizers from clumping. The motor 48 on the left side of the distribution frame 40 drives the rotating disk 49 to rotate. The distribution partition 410 on its outer wall quantitatively divides the material and transports it to the discharge pipe 41. Finally, the pear knife 44 at the bottom of the discharge pipe 41 completes the sowing or fertilization in the furrows on the ridge surface. With the integrated planting and fertilization component 4, sowing and fertilization can be completed simultaneously while ridging, integrating the three links of ridging, planting, and fertilization into a one-time operation. This reduces the number of times the equipment enters and exits the greenhouse and the operation process, significantly shortens the time cost of traditional step-by-step operations, and greatly improves the efficiency of the early preparation of greenhouse planting.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] During operation, the device first connects to an external traction device, such as a tractor, via the traction rod 10 on the front top of the fixed frame 1. Under traction, the entire device moves. The rollers 12 on the roller frame 11 at the front bottom of the fixed frame 1 contact the ground, and the protruding triangular steel bars on their outer walls rotate with the rollers 12 to prevent slippage, preparing for subsequent ridging. As the device moves forward, the ridge width adjustment component 2 on the rear bottom of the fixed frame 1 begins to work. According to planting needs, the self-locking motor 22 on the left side plate 20 is activated, driving the bidirectional lead screw 21 to rotate. Because the threads of the left and right sections of the bidirectional lead screw 21 are opposite, and the moving blocks on its outer walls... 24 is restricted from rotating by the upper sliding rod 23. The two moving blocks 24 move towards or away from each other along the bidirectional screw 21. The fixed rod 25 drives the bottom ridging pears 26 to adjust the spacing. Then the ridging pears 26 are inserted into the soil, and the broken soil is turned over to the middle to form a ridge of a set width. The width of the ridge can be flexibly changed by the ridge width adjustment component 2. It can meet the planting standards of various crops without changing the equipment, improve the versatility and applicability of the equipment. At the same time, by precisely adjusting the ridge width, space waste can be avoided, and reasonable dense planting can be achieved in the limited greenhouse space, thereby increasing the yield per unit area.

[0042] The leveling plate height adjustment component 3 at the rear of the equipment adjusts the formed ridges. Rotating the knob 32 causes the lead screw 31 to move axially along the threaded hole inside the rotating block 36. The rotating block 36 rotates in the rectangular groove inside the fixed plate 30 to prevent motion interference. The leveling plate 34 is driven to rotate around the connection point between the connecting rod 33 and the fixed frame 1 through the connecting block 35. After adjusting to a suitable height, the leveling plate 34 moves with the equipment. The chamfered structure at the bottom of the leveling plate smooths and compacts the soil on the ridge surface, realizing a one-time forming operation of ridging, planting, and fertilization. The leveling plate height adjustment component 3 can match ridge surfaces of different heights to ensure uniform smoothing of various ridge types, avoiding insufficient compaction or excessive rolling in some areas due to differences in ridge height, and improving the flatness of the ridges.

[0043] The planting and fertilization integrated component 4 at the top of the fixed frame 1 operates synchronously. Seeds or fertilizers stored in the pre-storage frame 42 fall into the distribution frame 40. During this process, the motor 45 on the front side of the pre-storage frame 42 drives the rotating rod 46 and the stirring rod 47 to rotate, preventing the seeds or fertilizers from clumping. The motor 48 on the left side of the distribution frame 40 drives the rotating disk 49 to rotate. The distribution partition 410 on its outer wall quantitatively divides the material and transports it to the discharge pipe 41. Finally, the pear knife 44 at the bottom of the discharge pipe 41 completes the sowing or fertilization in the furrows on the ridge surface. With the integrated planting and fertilization component 4, sowing and fertilization can be completed simultaneously while ridging, integrating the three links of ridging, planting, and fertilization into a one-time operation. This reduces the number of times the equipment enters and exits the greenhouse and the operation process, significantly shortens the time cost of traditional step-by-step operations, and greatly improves the efficiency of the early preparation of greenhouse planting.
