Description

Technical Field

[0001] The utility model relates to the technical field of agricultural production, in particular to a tomato seed uniform sowing device. Background Art

[0002] Tomato is an agricultural crop and one of the most commonly cultivated fruits and vegetables in the world. To grow tomatoes, the tomato seeds need to be sown into the soil for cultivation. There are mostly two ways to sow the seeds, one is to use a spreader, and the other is to sow them manually.

[0003] For example, the public document with application number 202022783538.8 discloses a high-quality pure white popping corn seed sowing device. The utility model is equipped with a second motor, a screw rod, an electric push rod, a compression spring, a guide column and a stopper. When the corn seeds enter the interior of the discharge pipe, under the action of the second motor and the electric push rod being electrically connected to the outside world, the second motor drives the screw rod to rotate, so that the movable block moves along the screw rod through the threaded sleeve, driving the electric push rod to move, and at the same time driving the telescopic rod to contract. During the movement, the electric push rod moves the block at one end into the slot of the guide column, and then the electric push rod contracts, and the force of the block on the slot is used to make the guide column compress the compression spring, thereby driving the stopper to move to the bottom end of the discharge pipe. When the seed falls into the upper part of the stopper, the second motor drives the screw rod to rotate in the opposite direction. The movable block drives the electric push rod to return. When the block leaves the slot, the compression spring rebounds and pushes the guide column to move at high speed along the guide sleeve. The rubber limit block on the upper mouth of the guide sleeve is used to limit and protect the guide column. The guide column drives the block to move at high speed to eject the corn seeds from the discharge pipe. This setting can effectively sow the seeds, improve the sowing efficiency, save time and effort. However, this sowing equipment, like the tomato seed sowing, belongs to the sowing device used for agricultural planting. When sowing seeds, this equipment directly ejects the seeds through the discharge pipe, which makes it difficult to effectively control the landing point of the seeds, resulting in inaccurate seed sowing and making the seed sowing position messy, making it difficult to achieve uniform and equidistant sowing at the same interval. Ejection sowing is also difficult to control the number of seeds sown in the same area.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a tomato seed uniform sowing equipment is proposed. Utility Model Content

The double-axis motor drives the rotating disks at both ends to rotate at a constant speed and the same frequency. When the bevel head block is flush with the through cavity, the thrust spring will push the baffle rod and the bevel head block to move and insert into the through cavity. At this time, the baffle rod will move out of the middle cavity of the front and rear bevel block blocks, thereby connecting the middle of the sowing tube for sowing. As the rotating disk continues to rotate, the inner wall of the through cavity will push the bevel head block and the baffle rod out of the through cavity through the bevel of the bevel head block, thereby pushing the baffle rod The rod is reinserted into the middle cavity of the inclined stopper to block the sowing tube, and the opening and closing of the sowing tube is controlled in such a reciprocating cycle, while the turntable rotates at a constant speed, so that the time for each movement of the stopper to open and close the sowing tube is the same, and the interval time for each operation of the stopper to open and close the sowing tube is the same, so that the tomato seeds can be sown in the same quantity after each sowing tube is opened, and sowed once every certain time and distance of movement of the device, and the seeds can be sown evenly, in equal quantities and at equal distances automatically;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, a tomato seed uniform sowing device comprises a connecting frame 1, a double-axis motor 2 is fixedly installed in the middle part above the surface of the connecting frame 1, a turntable 3 is arranged at both ends of the double-axis motor 2, a through cavity 4 is opened on the surface of the turntable 3, and a sowing pipe 5 is penetrated through the inner walls of the left and right ends of the surface of the connecting frame 1, and the inner surface of the sowing pipe 5 is located above the connecting frame 1 and has two inclined surface blocks 6 symmetrically arranged along the center, and an inclined head block 7 is arranged inside the through cavity 4, and a stopper rod 8 is fixedly installed at one end of the inclined head block 7 close to the sowing pipe 5, and a thrust spring 9 is sleeved on the outside of the stopper rod 8, one end of the thrust spring 9 is fixedly connected to the end of the inclined head block 7, and the other end of the thrust spring 9 is fixedly connected to the outer surface of the sowing pipe 5, the stopper rod 8 and the inclined surface block 6 are located in the same horizontal plane and slide through the sowing pipe 5, and the gap left in the middle part of the two inclined surface blocks 6 is just enough to enable the stopper rod 8 to be inserted and tightly fit with the two inclined surface blocks 6, and the width of the through cavity 4 and the inclined head block 7 is the same as the length of the stopper rod 8 at one end inside the sowing pipe 5.

[0023] Furthermore, the dual-axis motor 2 can drive the turntable 3 to rotate synchronously. The end of the bevel block 7 away from the sowing tube 5 is provided with a bevel, and the setting direction of the bevel is opposite to the rotation direction of the turntable 3. In the process of the dual-axis motor 2 driving the turntable 3 to rotate, when the side wall of the through cavity 4 is against the bevel on the bevel block 7, as the turntable 3 rotates, the bevel block 7 will move toward the direction close to the sowing tube 5, and then drive the gear rod 8 to enter the gap between the two bevel blocks 6 to prevent the seeds in the sowing tube 5 from falling. The bevel block 7 can be inserted into the through cavity 4 flush at the same time interval, and will stay in the through cavity 4 for the same length of time, and will be pushed out by the bevel, so as to control the gear rod 8 to open and close at the same time interval, and each opening and closing time length is the same, so that the seeds can be evenly sown in equal amounts and at equal distances.

[0024] Furthermore, the thrust spring 9 enables the blocking rod 8 and the bevel block 7 to be pushed into the through cavity 4 when they are aligned with the through cavity 4 , thereby opening the spreading tube 5 .

[0025] Furthermore, in the same sowing tube 5, the gaps left in the middle of the two inclined stoppers 6 on the front and rear sides can fit closely with the stopper rod 8, so that the stopper rod 8 can completely block the flow of seeds when inserted.

[0026] Furthermore, the two inclined stoppers 6 on the front and rear sides are both inclined toward the middle, so that after the stopper 8 is moved out to open the sowing tube 5, the seeds can flow downward smoothly and stably for sowing.

[0027] like Figure 1 and Figure 4 As shown, a double-slot material storage box 10 is fixedly installed on the upper end of the sowing tube 5, and the bottom ends of the slots on both sides of the double-slot material storage box 10 are arranged as inclined surfaces inclined toward the sowing tube 5, a push rod 11 is fixedly installed on the front end of the surface of the connecting frame 1, and a support rod 12 is fixedly installed on the middle part of the push rod 11, a connecting shaft 13 is rotatably provided on the inner wall of the bottom end of the connecting frame 1 through a bearing, and a moving mechanism 14 is provided at both ends of the connecting shaft 13, and the moving mechanism 14 consists of a wheel disc 1401, a convex rod 1402 and a fixed plate 1403, a wheel disc 1401 is fixedly installed on both ends of the connecting shaft 13, six convex rods 1402 are evenly distributed and fixedly provided on the surface of the wheel disc 1401, and a fixed plate 1403 is fixedly installed at the end of the convex rod 1402.

[0028] Furthermore, the two side troughs of the double-trough material storage box 10 can store materials, and the bottom is inclined, so that the seeds can flow to the sowing tubes 5 on both sides for simultaneous sowing, thereby improving the sowing efficiency.

[0029] Furthermore, the connecting shaft 13 rotates, thereby causing the moving mechanism 14 to rotate as a whole, pushing the device forward.

[0030] Furthermore, the moving mechanism 14 enables the device to contact the ground through a plurality of horizontally annularly arranged fixing plates 1403, thereby increasing the contact area between the device and the ground, dispersing the pressure, and enabling the device to move forward stably even in wet mud.

[0031] Furthermore, a flat plate-shaped fixing plate 1403 is used to replace the conventional circular wheel. During the movement, the flat plate-shaped fixing plate 1403 will generate vibration when rotating at intervals for mobile support, so that the entire device can be subjected to a certain vibration force to prevent seeds from being blocked in the sowing tube 5.

[0032] Working principle: When using the tomato seed uniform sowing equipment, first, pour the tomato seeds into the two side troughs of the double-trough storage box 10 respectively. The seeds will flow into the sowing tube 5 through the inclined surface and be blocked by the barrier surface formed by the blocking rod 8 and the inclined surface block 6. After the seeds are added, the push rod 11 is used to support the moving mechanism 14 to lift the entire device, and then the dual-axis motor 2 is started to push the entire device forward. By pushing the moving mechanism 14, the driving force is transmitted to the connecting shaft 13 to rotate, and then the moving mechanism 14 is rotated as a whole to push the device forward. The moving mechanism 14 makes the device contact with the ground through multiple horizontally annular fixed plates 1403, which increases the contact area between the device and the ground and disperses the pressure, so that the device can move forward stably even in wet mud. The fixed plate 1403 will vibrate during the movement, so that the entire device can be subjected to a certain vibration force to avoid the seeds from being blocked in the sowing tube 5. The dual-axis motor 2 drives the turntables at both ends. 3 rotates at a constant speed and frequency. When the inclined head block 7 is flush with the through cavity 4, the thrust spring 9 pushes the blocking rod 8 and the inclined head block 7 to move and insert into the through cavity 4. At this time, the blocking rod 8 moves out of the middle cavity of the two inclined surface blocking blocks 6 on the front and rear sides, thereby connecting the middle part of the sowing tube 5 for sowing. As the turntable 3 continues to rotate, the inner wall of the through cavity 4 pushes the inclined head block 7 and the blocking rod 8 out of the through cavity 4 through the inclined surface of the inclined head block 7, thereby pushing the blocking rod 8 to be reinserted into the middle cavity of the inclined surface blocking block 6, so that the sowing tube 5 Blocking, and controlling the opening and closing of the sowing tube 5 in such a reciprocating cycle, while the turntable 3 rotates at a constant speed, so that the time length of each movement of the blocking rod 8 to open and close the sowing tube 5 is the same, and the interval time of each operation of the blocking rod 8 to open and close the sowing tube 5 is the same, so that the tomato seeds can be sown in the same quantity each time the sowing tube 5 is opened, and sowed once every certain time and distance moved by the device. This is the working principle of the tomato seed uniform sowing equipment.
