Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to an integrated device for potato cutting and sowing. Background Art

[0002] Potatoes have high nutritional value and are rich in starch, protein, multiple vitamins, trace elements and other nutrients. Mechanical products are now widely used in agriculture. Potato cutting and sowing devices are ubiquitous, but most devices have single cutting and sowing functions. In addition, most of the existing potato planting devices do not have a spraying system, which requires spraying seeds before potato planting. The work efficiency is low, the labor intensity is heavy, and the liquid medicine is not mixed evenly, which is increasingly unable to meet user needs. These stages are often time-consuming and labor-intensive. Purchasing these two devices for sowing is even more time-consuming, labor-intensive, and costly. Utility Model Content

[0003] The utility model aims to provide an integrated potato cutting and sowing device, which integrates the functions of cutting, spraying and sowing, improves the mechanization level of potato sowing, saves costs, reduces labor intensity and improves planting efficiency.

[0004] The specific contents of the plan are as follows:

[0005] A potato seed cutting and sowing integrated device comprises a vehicle body, a seed cutting device, two groups of conveying devices and two groups of sowing devices. The vehicle body comprises a frame and wheels, the wheels are arranged on the four corners of the lower end of the frame, the seed cutting device is arranged at the rear end of the frame, the two groups of sowing devices are respectively arranged on the lower ends of the left and right sides of the frame, the two groups of conveying devices are respectively arranged on the upper end surfaces of the frames on the left and right sides of the seed cutting device, the lower ends of the seed cutting devices are respectively arranged above the rear ends of the corresponding conveying devices, the seed dropping opening end of each group of sowing devices is arranged on the frame end surface below the front end of the conveying device, and the conveying direction of the two groups of conveying devices is from the rear end of the frame to the front end of the frame.

[0006] The utility model integrates a seed cutting device, a conveying device, a spraying device and a sowing device on the same vehicle body. The seed cutting device can screen potatoes by size and evenly divide them to complete the seed cutting work. The seed potatoes enter the conveying device from the lower end of the seed cutting device, and the conveying device drives the seed potatoes to move forward. During the operation, the spraying device sprays the seed potatoes to prevent and control the occurrence of diseases and insect pests and improve the survival rate of the seed potatoes. When the seed potatoes run to the front end of the conveying device, they fall into the seed dropping tube of the sowing device arranged below the front end of the conveying device. The furrow opener of the sowing device is installed on the lower end surface of the front end of the frame. When the vehicle body moves forward, the furrow opener digs a furrow for sowing in the soil, and the seed potatoes fall into the furrow from the lower end of the seed dropping tube. The soil cover installed on the lower end surface of the rear end of the frame covers the seed potatoes with soil to complete the sowing. The utility model can improve the mechanization level of potato sowing, reduce labor intensity, save costs, and improve planting efficiency. The vehicle body includes a frame and wheels. A push handrail is provided at the rear end of the frame, and the planting personnel can push the vehicle body forward for sowing. A connection part for external power equipment is also provided at the front end of the frame, which can be connected to a self-propelled power equipment such as a tractor, and the tractor pulls the vehicle body for automatic sowing, which saves time and labor and improves planting efficiency.

[0007] Furthermore, the seed cutting device includes a frame, a screening plate and a cutting assembly. The frame is a rectangular structure, including four longitudinal beams and a screening channel, a seed potato conveying channel and a seed drop channel which are arranged nearly horizontally. The screening channel, the seed potato conveying channel and the seed drop channel are all arranged on the four longitudinal beams at an inclined interval with a higher upper end and a lower lower end. The lower ends of the screening channel, the seed potato conveying channel and the seed drop channel are all provided with gaps for the seed potatoes to fall. The screening plate is fixedly connected to the frame at an inclination toward the lower right front and is located above the screening channel. Both ends of the cutting assembly are fixedly connected to the left and right longitudinal beams at the gap at the lower end of the screening channel. The seed potato conveying channel is arranged below the screening channel, and the seed drop channel is arranged below the seed potato conveying channel and its lower ends are respectively arranged above the rear ends of the corresponding conveying devices.

[0008] The seed cutting device is a rectangular structure as a whole, and the screening plate, screening channel, seed potato conveying channel and seed dropping channel are all obliquely arranged on the longitudinal beam of the frame. The screening plate is tiltedly arranged at the top of the frame, the right front end of the screening plate is the lowest point, and the screening channel is located below the screening plate. After the potatoes are classified by size through the screening plate, they fall into the screening channel. Multiple cutters are installed at the lower end of the screening channel. The motor rotates to drive the transmission shaft to rotate, and the cutters installed on the transmission shaft also rotate accordingly to cut the potatoes that slide down into uniform seed potatoes. The cut seed potatoes fall from the gap at the lower end of the screening channel into the seed potato conveying channel located below the screening channel, and then slide down from the gap at the lower end of the seed potato conveying channel and fall into the lowest seed drop channel. The seed drop channel includes a first channel and a second channel. The upper ends of the first channel and the second channel are connected, and the lower ends of the first channel and the second channel are gradually narrowed. At the ends of the first channel and the second channel, seed drop openings extending beyond the left and right sides of the frame are provided. The width of the seed drop opening is set to be close to the width of a seed potato to ensure that the seed potatoes can only fall from the seed drop opening to the rear end of the conveying device piece by piece. A downward guide plate may also be provided at the gap at the lower end of each channel to ensure that all the seed potatoes fall into the channel below.

[0009] Furthermore, the screening plate includes a large potato screening area and a small potato screening area. The large potato screening area includes a large potato dropping hole, which is arranged at the right front end of the screening plate. The small potato screening area is evenly provided with multiple small potato dropping holes. The screening channel includes a large potato channel and a small potato channel. The large potato channel is open at both ends, the right side of the large potato channel is higher than the left side, the upper end opening of the large potato channel is arranged directly below the large potato dropping hole, the small potato channel is an open channel and is arranged on the left side of the large potato channel, and the lower end openings of the large potato channel and the small potato channel are both arranged above the upper end of the seed potato conveying channel.

[0010] The angle between the screening plate and the horizontal plane is 13-15 degrees, and the inclination angle is small, so that the speed of the potatoes rolling down after being poured on the screening plate is relatively slow, and the potatoes can be completely separated by size. The large potatoes will not fall into the small potato drop hole after rolling through the small potato screening area; the small potatoes will not directly fall into the large potato drop hole at the right front end due to the excessive rolling speed, and the large potatoes and small potatoes can be completely separated. The potatoes after screening fall into the corresponding large potato channel and small potato channel from the large potato drop hole and the small potato drop hole respectively, and the large and small potatoes slide to the lower ends of the large potato channel and the small potato channel respectively, and are cut into small pieces by the cutters installed at the lower ends of the large potato channel and the small potato channel. The upper and lower ports of the large potato channel are open, and the upper end opening of the large potato channel is located below the large potato drop hole. The right side of the large potato channel is higher than the left side, so that the small potatoes that fall on the upper end surface of the large potato channel can slide into the small potato channel. This closed design can prevent small potatoes from falling from the small potato drop hole into the large potato channel, ensuring the accuracy of screening. The vehicle body can provide vibration for the screening plate during the movement, so that the potatoes can roll along the screening plate and will not stay on the screening plate.

[0011] Furthermore, the cutting assembly includes a cutting motor, a transmission shaft and multiple cutters. The multiple cutters are arranged at intervals on the transmission shaft and adjacent to the upper end surface of the lower end of the screening channel. Both ends of the transmission shaft are fixedly connected to the left and right side walls of the frame. One end of the transmission shaft is exposed outside the left or right side wall of the frame and is transmission-connected to the cutting motor.

[0012] The transmission shaft of the cutting assembly is arranged horizontally and its two ends are fixedly mounted on the left and right side walls of the frame. One end of the transmission shaft extends out of the side wall of the frame and is connected to the cutting motor. After the cutting motor is started, the transmission shaft is driven to rotate, and the cutter installed on the transmission shaft rotates accordingly to cut the falling potatoes. The number of cutters is set according to actual needs.

[0013] Furthermore, the horizontal distance between adjacent cutters arranged at the lower end of the large potato channel is smaller than the horizontal distance between adjacent cutters arranged at the lower end of the small potato channel.

[0014] The number of cutters installed at the bottom of the large potato channel is greater than that of the small potato channel, and the distance between two adjacent cutters at the bottom of the large potato channel is smaller than that of two adjacent cutters at the bottom of the small potato channel, that is, the cutters at the bottom of the large potato channel are arranged more densely. This can effectively control the uniform cutting of potatoes and prevent the uneven sizes of cut seed potatoes from affecting the planting effect.

[0015] Furthermore, leakage holes are evenly distributed on the seed potato conveying channel and the seed dropping channel.

[0016] After potatoes are cut, starch liquid will flow out and it is very easy to stick to the channel. In order to avoid this situation, leakage holes are evenly arranged on the seed potato conveying channel and the seed dropping channel so that the starch liquid can leak out from the holes. In addition, because of the setting of the leakage holes, the ventilation effect is good, the seed potato incision can dry quickly, and it is not easy for the seed potato to stick to the channel and cannot slide down.

[0017] Furthermore, the seed drop channel includes a first channel and a second channel, both of which are structures that are wide at the top and narrow at the bottom, and the upper ends of the two are connected to each other, and the lower end of the seed potato conveying channel is arranged above the connection between the first channel and the second channel, and the ends of the first channel 1 and the second channel are both provided with seed drop ports, and the two seed drop ports respectively extend out of the frame and are arranged above the rear end of the conveying device on the same side.

[0018] The seed potatoes fall from the seed drop channel and land on the conveying device. After being sprayed, they are transported to the upper opening of the seed drop tube by the conveying device, and then fall into the seed drop tube and into the trench dug by the furrow opener, and are finally covered by the soil to complete the sowing.

[0019] Furthermore, the spraying device includes a medicine box, a submersible pump, a battery, two nozzles and multiple water pipes. The submersible pump is arranged in the medicine box, the battery is fixedly connected to the outer wall and the electric wire is connected to the submersible pump, the two nozzles are respectively connected to the water outlet of the submersible pump through corresponding water pipes, the two nozzles are respectively fixedly connected to the left and right outer walls of the medicine box, and the nozzle of each nozzle is downwardly arranged above the middle of the conveying device on the same side.

[0020] The medicine box of the spraying device is fixedly installed on the front end of the frame, and a submersible pump is installed in the medicine box. The function of the submersible pump is to extract the medicine into the connected water pipe and spray it out from the nozzle, and spray it on the cut seed potatoes on the conveyor chain, which can sterilize the cut of the seed potatoes, ensure the survival rate of the seed potatoes, and prevent and control diseases and insect pests. The submersible pump needs to be powered by a power supply, so a battery needs to be installed on the outer wall of the medicine box, and the battery is connected to the submersible pump wire. The submersible pump can select the appropriate power according to actual needs, and a submersible pump can form multiple water outlets through a water pipe connection. Because there are two conveying devices on the left and right sides of the medicine box seed cutting device, it is necessary to have two nozzles with nozzles fixed downward on the top of the corresponding conveying devices.

[0021] Furthermore, two groups of seeding devices are respectively fixedly connected to the left and right sides of the frame, each group of seeding devices includes a furrow opener, a seed drop tube and a soil cover, the furrow opener, seed drop tube and soil cover on the same side are located in the same straight line, the two furrow openers are respectively fixedly connected to the lower end surfaces on the left and right sides of the front end of the frame, the two soil covers are respectively fixedly connected to the lower end surfaces on the left and right sides of the rear end of the frame, each soil cover is a V-shaped structure and the opening is set forward, the upper ends of the two seed drop tubes are respectively opened on the upper end surfaces on the left and right sides of the frame and are located between the furrow opener and the soil cover, and the lower end opening of the seed drop tube is located below the frame

[0022] After the seed potatoes are sprayed, they are transported by the conveying device to the top of the upper opening of the seed tube of the sowing device, and the seed potatoes fall into the seed tube. The furrow opener is installed on the lower end surface of the front end of the frame, and the soil is furrowed when the vehicle body is moving. The seed tube, furrow opener and soil coverer on the same side are located in the same straight line. The seed tube is located between the furrow opener and the soil coverer. The seed potatoes fall from the seed tube and fall into the groove opened by the furrow opener. As the vehicle body moves, the soil coverer installed on the lower end surface of the rear end of the frame covers the seed potatoes with soil, thereby completing the sowing work. The soil coverer is a V-shaped structure, which can gather the soil accumulated on both sides of the groove inward to bury the seed potatoes. The sowing device consists of two groups, which are respectively arranged on the left and right sides of the frame. The utility model can complete single-ridge double-row sowing, which can meet the sowing methods in most areas.

[0023] Furthermore, each group of conveying devices includes a conveying motor, a conveying chain, a frame and a conveyor belt. The motor and conveying chain of each group are arranged on the frame, the conveyor belt is arranged on the conveying chain, each motor is drivingly connected to the conveying chain on the same side, the lower ends of the two frames are respectively fixedly connected to the upper end surfaces on the left and right sides of the frame, the conveyor belt is arranged below the seed drop port and the nozzle, and the upper end opening of the seed drop tube is arranged below the front end of the conveyor belt.

[0024] Two sets of conveying devices are arranged in conjunction with two sets of sowing devices. The conveying chain moves from back to front. The cut seed potatoes fall onto the conveyor belt and are transported to the front end of the frame. The spraying device sprays the seed potatoes with medicine for sterilization and disinfection, and then continues to transport them forward. When they reach the end of the front end of the conveyor belt, the seed potatoes fall into the upper opening of the seed drop tube arranged below the front end of the conveying chain, slide from the seed drop tube into the groove opened by the furrow opener, and are covered with soil by the soil cover at the rear end to complete the sowing.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] 1. The seed cutting device of the utility model can make the seed potatoes cut out more uniform in size and effectively control the uniform cutting of potatoes, thereby preventing the seed potatoes cut out of different sizes from affecting the planting effect;

[0027] 2. The spraying device of the utility model sprays the seed potatoes with medicine, which can sterilize and disinfect the cuts of the seed potatoes, improve the quality of the seed potatoes, and increase the survival rate of the seed potatoes;

[0028] 3. The utility model integrates the functions of cutting, spraying and sowing, and aims to improve the problem that the existing potato sowing device cannot cut and disinfect potatoes, and the problem that the existing potato cutting device cannot disinfect and sow.
